    T.C. Memo. 2022-91
    JOHANNES LAMPRECHT AND LINDA LAMPRECHT,
    Petitioners
    v.
    COMMISSIONER OF INTERNAL REVENUE,
    Respondent
    —————
    Docket No. 14410-15.                             Filed August 31, 2022.
    —————
    Ps are citizens of Switzerland who lawfully resided
    in the United States, where P–H worked as an investment
    consultant managing investments for himself and his
    clients. Ps filed U.S. income tax returns for 2006 and 2007
    which understated their income in both years by omitting
    income that Ps treated as foreign sourced.
    In 2008 the IRS issued to Swiss Bank a John Doe
    summons which sought to discover the identities of U.S.
    taxpayers using foreign entities and Swiss bank accounts
    to avoid reporting income on their U.S. tax returns.
    In 2010 Ps filed amended returns for 2006 and 2007
    on which they reported the previously omitted income.
    Upon examination of Ps’ 2006 and 2007 returns, R
    determined an accuracy-related penalty under I.R.C.
    § 6662 against Ps for each year on the basis of the tax
    attributable to the income omitted from the original
    returns, and issued to Ps a notice of deficiency. Ps timely
    filed a petition to challenge the penalty determinations in
    the notice of deficiency, arguing (1) that the IRS failed to
    comply with I.R.C. § 6751(b)(1) requiring written
    supervisory approval of penalties, (2) that their amended
    returns for 2006 and 2007 are “qualified amended returns”
    within the meaning of 
    Treas. Reg. § 1.6664-2
    (c)(3),
    Served 08/31/22
    2
    [*2] precluding penalty liability, and (3) that assessment of the
    accuracy-related penalties for 2006 and 2007 is barred by
    the statute of limitations under I.R.C. § 6501.
    Held: The amended returns are not “qualified
    amended returns” under 
    Treas. Reg. § 1.6664-2
    (c)(3)(i)(D)
    because they were filed after the service of a John Doe
    summons.
    Held, further, assessment of the accuracy-related
    penalties is not barred by the statute of limitations under
    I.R.C. § 6501 because the limitations period was suspended
    by the service of the John Doe summons pursuant to I.R.C.
    § 7609(e)(2).
    Held, further, the IRS complied with the written
    supervisory approval requirement of I.R.C. § 6751(b)(1).
    Held, further, Ps are liable for the I.R.C. § 6662
    accuracy-related penalties as determined by R for the 2006
    and 2007 years.

    MEMORANDUM OPINION
    GUSTAFSON, Judge: This case is before the Court pursuant to
    section 6213(a) 1 for redetermination of accuracy-related penalties under
    1 Unless otherwise indicated, statutory references are to the Internal Revenue
    Code (“the Code”, Title 26 of the United States Code) as in effect at the relevant times;
    references to regulations are to Title 26 of the Code of Federal Regulations (“Treas.
    Reg.”) as in effect at the relevant times; and references to Rules are to the Tax Court
    Rules of Practice and Procedure. Some dollar amounts are rounded. Citation in this
    opinion to a “Doc.” refers to a document so numbered in the Tax Court docket record of
    this case, and a pinpoint citation therein refers to the pagination as generated in the
    portable document format (“PDF”) file.
    3
    [*3] section 6662(a) that the Internal Revenue Service (“IRS”)
    determined against petitioners, Johannes and Linda Lamprecht, for the
    tax years 2006 and 2007. Pursuant to section 6212(a), the IRS mailed a
    statutory notice of deficiency (“NOD”) to the Lamprechts on January 9,
    2015, determining accuracy-related penalties under section 6662(a) of
    $124,294 for 2006 and $376,449 for 2007. The NOD determined these
    penalties on the basis of substantial understatements of income tax
    under section 6662(b)(2) and (d). 2 Both parties have moved for summary
    judgment under Rule 121, and the issues for decision are whether a
    genuine dispute of material fact exists with respect to: (1) whether the
    Lamprechts are liable for the accuracy-related penalties imposed by
    section 6662 for the 2006 and 2007 years, and, if so, (2) whether
    assessment of those penalties is barred by the statute of limitations
    under the provisions of section 6501. We hold that the Lamprechts are
    liable for the section 6662 accuracy-related penalties for 2006 and 2007
    as determined by the Commissioner, and that assessment of the
    penalties is not barred by the statute of limitations. For the reasons
    stated below, we will grant the Commissioner’s motion, deny petitioners’
    motion, and enter judgment for the Commissioner as a matter of law.
    Background
    The following facts are derived from the pleadings and the parties’
    respective motions, memorandums, and accompanying declarations
    (including the exhibits attached thereto). Unless noted otherwise, these
    facts are not in dispute.
    The Lamprechts’ business activities
    The Lamprechts are, and have always been, citizens of
    Switzerland. In 2006 and 2007, they held visas entitling them to lawful
    permanent residence in the United States (i.e., “green cards”). The
    Lamprechts maintained residences in Tiburon, California, and
    St. Moritz, Switzerland, and periodically rented their St. Moritz
    residence to third parties.
    Mr. Lamprecht worked in the United States as an investment
    consultant for Trais Fluors Investment Services, Inc. (“Trais Fluors”), a
    2 The NOD also determined, as an alternative basis for the penalties,
    negligence under section 6662(c), but we will grant the Commissioner’s motion and
    sustain the penalties without reaching the issue of negligence. In his answer the
    Commissioner also asserted fraud penalties under section 6663, but he later conceded
    them.
    4
    [*4] California corporation for which he was both an officer and the sole
    shareholder. Mr. Lamprecht received a salary from Trais Fluors, as well
    as interest, dividends, and capital gains from his personal investment
    activities.
    Mr. Lamprecht and UBS
    In the years at issue, Mr. Lamprecht also received commissions
    from the Swiss bank UBS AG (“UBS”) for referrals of business to it. The
    commissions were deposited into one of Mr. Lamprecht’s UBS accounts.
    (As we set out below, the Lamprechts did not report these commissions
    on their original 2006 and 2007 Forms 1040, “U.S. Individual Income
    Tax Return”, but did report them on their Forms 1040–X, “Amended
    U.S. Individual Income Tax Return”.) 3
    Mr. Lamprecht is an owner of Paro, Inc. (“Paro”), 4 an entity
    incorporated under the laws of the British Virgin Islands. In the years
    at issue, Paro maintained a UBS bank account, of which Mr. Lamprecht
    was a beneficial owner.
    Departure from the United States
    Mr. Lamprecht departed the United States on December 9, 2009,
    and submitted U.S. Citizenship and Immigration Service Form I–407,
    “Abandonment of Lawful Permanent Resident Status”, to the American
    Embassy in Bern, Switzerland, on December 21, 2009. Mr. Lamprecht
    also filed Form 8854, “Expatriation Information Statement”, with the
    IRS in December 2010. Mrs. Lamprecht departed the United States on
    October 17, 2010, and surrendered her green card to the U.S. authorities
    in Switzerland on November 30, 2010.
    3  In opposition to the Commissioner’s motion for summary judgment, the
    Lamprechts submitted, as Exhibit 15, a declaration by Mr. Lamprecht that stated: “the
    amounts that I reported on Schedule C[, “Profit or Loss From Business”,] of my
    amended 2006 and 2007 tax returns . . . are commissions that I was paid by UBS A. G.
    (‘UBS’) for placing business with them. The amounts all appear on the UBS
    statements that . . . appear on Exhibit 13”. That “Exhibit 13” appears in our record as
    Doc. 127.
    4 The parties disagree on the percentage of Mr. Lamprecht’s ownership of Paro.
    The Lamprechts contend they own 100% of Paro as community property under the
    laws of the State of California. We need not resolve this dispute.
    5
    [*5] The Lamprechts’ original 2006 and 2007 federal income tax returns
    The Lamprechts engaged a return preparer to prepare their
    original federal income tax returns for the 2006 and 2007 years, and
    they filed those returns early. The 2006 return is treated as having been
    filed on the due date in April 2007, and the 2007 return is treated as
    having been filed on the due date in April 2008. See § 6501(b)(1).
    Their original 2006 return reported income totaling $1,073,761,
    and their original 2007 return reported income totaling $1,705,314. (As
    they now admit, and as we show below, that reporting was short by
    about $1 million for 2006 and about $5 million for 2007.) The original
    returns did not report income from commissions Mr. Lamprecht received
    from UBS (and that were deposited into his UBS accounts) or from
    foreign-source interest, dividends, and capital gains. 5 On Schedule A,
    “Itemized Deductions”, to each return, they claimed itemized
    deductions.
    On their original 2006 return on Schedule B, “Interest and
    Ordinary Dividends”, Part III, “Foreign Accounts and Trusts”, the
    Lamprechts completed line 7a (“At any time during 2006, did you have
    an interest in or a signature or other authority over a financial account
    in a foreign country, such as a bank account, securities account, or other
    financial account?”) by putting an X in the “No” column. They left blank
    line 7b (“If ‘Yes,’ enter the name of the foreign country”). They did the
    same on their original 2007 return.
    The 2008 John Doe summons proceeding
    The Department of Justice (“DOJ”) filed an “Ex Parte Petition for
    Leave to Serve John Doe Summons” 6 in the U.S. District Court for the
    Southern District of Florida, styled as “In the Matter of the Tax
    Liabilities of: John Does”, No. 08-21864 (June 30, 2008). The petition
    5  The Lamprechts do not attribute these omissions to their paid return
    preparer, nor do they otherwise assert “reasonable cause” for their errors under
    section 6664(c). Mr. Lamprecht informed the IRS during examination that the reason
    for his non-reporting was that he “thought that ‘everything Swiss was not taxable in
    the U.S.’” However, because we need not reach in this opinion the issues of negligence
    or fraud, we need not determine his subjective reasons for the errors.
    6 A “John Doe summons” is a third-party summons that “does not identify the
    person with respect to whose liability the summons is issued.” § 7609(f).
    6
    [*6] requested authorization to serve a John Doe summons on UBS
    seeking information regarding the following class of persons:
    United States taxpayers, who at any time during the years
    ended December 31, 2002 through December 31, 2007, had
    signature or other authority . . . with respect to any
    financial accounts maintained at, monitored by, or
    managed through any office in Switzerland of UBS AG or
    its subsidiaries or affiliates and for whom UBS AG or its
    subsidiaries or affiliates (1) did not have in its possessions
    Forms W–9 executed by such United States taxpayers, and
    (2) had not filed timely and accurate Forms 1099 naming
    such United States taxpayers and reporting to United
    States taxing authorities all reportable payments made to
    such United States taxpayers.
    Finding that the UBS John Doe summons met the requirements of
    section 7609(f), the district court authorized its service upon UBS by
    order dated July 1, 2008. UBS did not participate in this ex parte
    proceeding (nor did the Swiss government).
    Service of the summons on UBS
    The IRS served the John Doe summons on UBS on July 21, 2008,
    requesting records regarding: (1) the identities of U.S. taxpayers in the
    specified class; (2) foreign entities established or operated on behalf of
    each U.S. taxpayer in the class; (3) the opening of financial accounts,
    monthly or other periodic statements of activities of such accounts, and
    annual summaries of such accounts; and (4) referrals of each U.S.
    taxpayer in the class to UBS offices in Switzerland. The summons
    required appearance before the IRS in Miami, Florida, on August 8,
    2008, for testimony and production of the requested records.
    The 2009 summons enforcement proceeding
    On February 19, 2009, 7 DOJ filed a petition in District Court for
    the Southern District of Florida to enforce the UBS John Doe summons,
    7  In this same general period, the IRS announced the Offshore Voluntary
    Disclosure Program (“2009 OVDP”). See Statement, IRS Newsroom, “Statement from
    IRS Commissioner Doug Shulman on Offshore Income” (Mar. 26, 2009),
    https://www.irs.gov/newsroom/statement-from-irs-commissioner-doug-shulman-on-
    offshore-income. Through the 2009 OVDP, taxpayers with previously unreported
    7
    [*7] styled as United States v. UBS AG, No. 09-20423. The government
    of Switzerland joined in the enforcement suit as amicus curiae. The
    enforcement suit was ultimately resolved through two related out-of-
    court agreements, both executed August 19, 2009:
    The first agreement, known as the “U.S.-Switzerland
    Agreement”, 8 established an agreed mechanism for exchanging
    information that would “achieve the U.S. tax compliance goals of the
    UBS [John Doe] Summons while also respecting Swiss sovereignty.”
    Under the U.S.-Switzerland Agreement, the IRS would deliver “a
    request for administrative assistance pursuant to Article 26 of the 1996
    Convention Between the United States of America and the Swiss
    Confederation for the Avoidance of Double Taxation with Respect to
    Taxes on Income” 9 to the Swiss Federal Tax Administration (“SFTA”)
    seeking information regarding accounts of U.S. taxpayers maintained at
    UBS in Switzerland.
    The second agreement, known as the “U.S.-UBS Agreement”, was
    the settlement agreement between the United States, the IRS, and UBS,
    by which the parties agreed to three terms pertinent to this opinion:
    First, as to the information sought by the summons, they agreed that
    UBS would produce the documents requested in the UBS John Doe
    summons to the SFTA on a rolling basis pursuant to an agreed-upon
    schedule and that UBS’s compliance would be monitored by the Swiss
    Federal Office of Justice and the Swiss Financial Market Supervisory
    Authority.
    offshore income could avoid potential criminal prosecution if they notified the IRS and
    met other conditions. Taxpayers who did not participate in the 2009 OVDP would be
    subject to the full extent of civil and criminal liability and all available penalties for
    each year. The extended deadline for taxpayers to participate in the 2009 OVDP was
    October 15, 2009. See IRS News Release IR-2009-84 (Sept. 21, 2009). The Lamprechts
    did not participate in the 2009 OVDP, and they have asserted in this case that the
    reason for their non-participation was that they were unable to obtain necessary
    documents from UBS, a contention that the Commissioner argued they are barred from
    making. The parties did not address the 2009 OVDP in their briefing of the cross-
    motions for summary judgment, so we do not address it further here.
    8The U.S.-Switzerland Agreement does not appear in our record, but it is
    described in the second agreement discussed here—the U.S.-UBS agreement.
    9 See generally Convention for the Avoidance of Double Taxation with Respect
    to Taxes on Income, Switz.–U.S., Oct. 2, 1996, T.I.A.S. No. 97-1219.
    8
    [*8] Second, as to the summons enforcement case, the parties agreed
    to its dismissal and expressed their understanding about the effect of
    that dismissal. They agreed as follows:
    Immediately upon the execution of this Settlement
    Agreement, and in no event more than 5 business days
    after its execution, UBS and the United States will file a
    Stipulation of Dismissal, pursuant to Fed. R. Civ.
    P. 41(a)(l)(A)(ii), with the United States District Court for
    the Southern District of Florida. . . . The Parties
    understand that the dismissal of the Action pursuant to
    this paragraph 1 shall, in and of itself, have no effect on the
    UBS Summons or its enforceability.
    Third, as to the UBS John Doe summons itself, the parties agreed
    that the IRS would “withdraw with prejudice” the UBS John Doe
    summons after receiving information concerning bank accounts from
    UBS pursuant to the treaty request for administrative assistance.
    However, the parties agreed that “if UBS fails to comply in any material
    respect with any of its obligations” to produce information, then “the IRS
    is not obligated to withdraw the UBS Summons”. That is, under this
    agreement, although the summons enforcement suit would be promptly
    dismissed, the summons itself would remain pending and potentially
    enforceable until it was “withdrawn with prejudice” after UBS provided
    the information.
    The IRS formally withdrew the UBS John Doe Summons, “with
    prejudice”, on November 15, 2010. Information produced by UBS in
    response to the John Doe summons included the Lamprechts’ account
    information.
    The Lamprechts’ amended 2006 and 2007 federal income tax returns
    In December 2010—after UBS had given its information to the
    IRS and the John Doe summons had been withdrawn—the Lamprechts
    filed amended federal income tax returns for the 2006 and 2007 years,
    which were prepared by a paid preparer. On the amended returns, the
    Lamprechts reported their previously unreported income. Certain
    amounts they reported on their original and amended returns for 2006
    and 2007 compare as follows:
    9
    [*9] Item        2006 original   2006 amended     2007 original   2007 amended
    Adjusted
    $1,073,652       $2,816,833      $1,705,172      $6,930,169
    gross income
    Itemized
    187,338          152,481         202,497        128,460
    deductions
    Total tax           240,393          861,864          461,798      2,344,041
    Thus, the amended returns showed increases in tax liability of
    $621,471 for 2006 and $1,882,243 for 2007. On lines 7a and 7b of
    Schedule B to their amended returns, the Lamprechts answered “Yes”
    to the question whether they had an interest in “a financial account in
    a foreign country” and entered “Switzerland” as the name of the foreign
    country. The Lamprechts concurrently filed Forms TD F 90-22.1,
    “Report of Foreign Bank and Financial Accounts” (“FBAR”), 10 for 2006
    and 2007 to report previously undisclosed foreign bank accounts.
    When they filed their amended returns in December 2010, the
    Lamprechts paid the increased tax liabilities for 2006 and 2007 that
    they reported. (They did not report a liability for penalties nor pay
    them.)
    IRS examination
    The Lamprechts’ 2010 federal income tax return, filed in or before
    April 2011, was selected for examination and was assigned to Revenue
    Agents (“RA”) Norbert Nyereyemhuka and Sandra Lyons.                 The
    Lamprechts did not participate in the examination of their federal
    income tax return by phone conference—only through their attorney,
    Mr. De Vos, who traveled to Dallas, Texas, in September 2014, for a
    meeting with the examiners.
    In a Form 4564, “Information Document Request”, dated
    December 12, 2013, RA Nyereyemhuka requested that the Lamprechts
    provide copies of their original and amended tax returns for the 2003,
    2004, 2005, 2006, 2007, and 2008 years. On February 12, 2014,
    RA Nyereyemhuka submitted to his immediate supervisor, Robert
    Davis, a Form 5345–D, “Examination Request-ERCS (Examination
    Returns Control System) Users”, requesting that the Lamprechts’
    return for the 2007 year be opened for examination for the purpose of
    assessing the section 6662 accuracy-related penalty. The form states,
    10 Form TD F 90-22.1 was the appropriate FBAR form for 2006 and 2007, but
    it was replaced by FinCEN Form 114 starting in January 2014.
    10
    [*10] as the “Reason for Request: To open up 2007 tax year to assess
    penalties on amended return that does not meet the qualified amended
    return criteria.” (Emphasis added.) The form then states: “Follow-Up
    Actions: Open up tax year / Assess accuracy penalty.” (Emphasis added.)
    Mr. Davis approved RA Nyereyemhuka’s request by signing the form.
    RA Nyereyemhuka made an identical request to open the Lamprechts’
    return for the 2006 year for examination to assess the section 6662
    accuracy-related penalty via a Form 5345–D dated April 10, 2014, which
    Acting Supervisory Revenue Agent Michael Anderson approved that
    same day by signing the form.
    The IRS first communicated to the Lamprechts its determination
    that they were liable for the section 6662 accuracy-related penalties for
    the years 2006 and 2007 in a Letter 950 dated July 18, 2014, which
    included copies of Form 4549, “Income Tax Examination Changes”, and
    Form 886–A, “Explanation of Items”, detailing the facts and law
    supporting its determination.
    RA Nyereyemhuka’s group manager later signed a “Civil Penalty
    Approval Form” dated November 4, 2014, again approving assessment
    of the section 6662 accuracy-related penalties against the Lamprechts
    for the 2006 and 2007 years.
    The Statutory Notice of Deficiency for 2006 and 2007
    On January 9, 2015, the IRS mailed to the Lamprechts an NOD
    determining the section 6662 accuracy-related penalties for 2006 and
    2007. Attached to the NOD were Forms 4549–A, “Income Tax
    Examination Changes”, determining section 6662 accuracy-related
    penalties for 2006 and 2007, and Form 886–A providing
    RA Nyereyemhuka’s analysis of the facts and law supporting his
    decision to assert section 6662 accuracy-related penalties for 2006 and
    2007.
    The Lamprechts’ petition
    The Lamprechts challenged the IRS’s determination by timely
    filing a petition with the Tax Court. When they filed their petition, the
    Lamprechts resided in Switzerland. 11 The Lamprechts do not dispute
    the arithmetic of the IRS’s calculations of the accuracy-related penalties
    11 Absent stipulation pursuant to section 7482(b)(2), venue for an appeal in this
    case would be the U.S. Court of Appeals for the District of Columbia. See § 7482(b)(1).
    11
    [*11] for 2006 and 2007 as shown on the NOD, but they dispute the
    applicability of those penalties. The petition makes two primary
    contentions challenging the accuracy-related penalties. First, the
    petition claims that the Lamprechts fixed their own errors and should
    not be penalized. It contends that their amended returns for 2006 and
    2007 are “qualified amended returns” within the meaning of Treasury
    Regulation section 1.6664-2(c)(3), and that therefore there is no
    underpayment to which the accuracy-related penalties may apply.
    Second, the petition claims that assessment of the accuracy-related
    penalties for 2006 and 2007 is barred by the statute of limitations under
    section 6501.
    The parties’ cross-motions for summary judgment
    Following a lengthy series of discovery disputes, 12 the
    Commissioner filed his motion for summary judgment, and the
    Lamprechts cross-moved. Stated simply, the issue for decision is
    whether the Lamprechts are liable for 20% accuracy-related penalties
    (under section 6662(a)) for “substantial understatements” of tax (under
    section 6662(b)(2)) on their original returns for 2006 and 2007. 13 The
    Lamprechts do not dispute that the understatements on their original
    returns were “substantial” (i.e., exceeding the greater of 10% of their tax
    or $5,000, see § 6662(d)), and they do not raise a defense of “reasonable
    basis” under section 6662(d)(2)(B)(ii)(II) nor “reasonable cause” under
    section 6664(c). Rather, they make three other contentions, any one of
    which would carry the day.
    First, the Lamprechts contend that the “initial determination” of
    the penalties was not given written supervisory approval as required by
    section 6751(b)(1) (an issue not raised in the petition, but on which the
    Commissioner bears the burden of production). Second, the Lamprechts
    contend (as in their petition) that their amended returns were “qualified
    amended returns” that cured their errors and preclude penalty liability.
    And third, they continue to contend that the statute of limitations bars
    the assessment of the determined penalties. These are the issues that
    we address in this opinion.

    13 The Commissioner also maintains his alternative position that the penalties
    are warranted by “negligence” under section 6662(b)(1), but he does not assert that
    more fact-intensive contention in his motion for summary judgment.

    [*12]                           Discussion
    I.      General principles of law
    A.    Jurisdiction
    The Lamprechts’ petition was filed pursuant to section 6213(a),
    which grants the Court jurisdiction to redetermine a deficiency in
    federal income tax as determined in an NOD. However, the Lamprechts
    paid their increased federal income tax liabilities for 2006 and 2007
    when filing their amended returns, and the only liabilities at issue are
    the section 6662 accuracy-related penalties. Section 6665(a) provides
    that “the . . . penalties provided by this chapter [68, titled “Additions to
    Tax, Additional Amounts, and Assessable Penalties”] shall . . . be
    assessed, collected, and paid in the same manner as taxes”, and further
    that “any reference in this title [26 U.S.C.] to ‘tax’ imposed by this title
    shall be deemed also to refer to the additions to the tax, additional
    amounts, and penalties provided by this chapter.” Under these
    provisions the Commissioner’s determination that the Lamprechts are
    liable for the section 6662 accuracy-related penalties for 2006 and 2007
    is equivalent to his determining a deficiency in federal income tax for
    those years; and upon the timely filing of their petition, we have
    jurisdiction to redetermine that deficiency. See §§ 6213(a), 6665(a).
    B.    Summary judgment
    The purpose of summary judgment is to expedite litigation and
    avoid unnecessary trials. Fla. Peach Corp. v. Commissioner, 
    90 T.C. 678
    , 681 (1988). The Court may grant summary judgment when there
    is no genuine dispute as to any material fact and a decision may be
    rendered as a matter of law. Rule 121(b); Sundstrand Corp. v.
    Commissioner, 
    98 T.C. 518
    , 520 (1992), aff’d, 
    17 F.3d 965
     (7th Cir. 1994).
    The moving party bears the burden of showing that no genuine
    issue of material fact exists, and the Court will view any factual material
    and inferences in the light most favorable to the nonmoving party.
    Dahlstrom v. Commissioner, 
    85 T.C. 812
    , 821 (1985). Since we will grant
    the Commissioner’s motion for summary judgment, we will draw
    inferences in favor of the Lamprechts.
    C.    Accuracy-related penalty
    Section 6662(a) imposes an “accuracy-related penalty” equal to
    20% of the portion of the underpayment that is attributable to various
    13
    [*13] factors, including a “substantial understatement of income tax”.
    § 6662(b)(2). For the purposes of section 6662(b)(2) and (d)(1)(A), an
    understatement 14 of income tax is “substantial” if it exceeds the greater
    of “10 percent of the tax required to be shown on the return” or $5,000.
    § 6662(d)(1)(A). There is no dispute that the understatements on the
    Lamprechts’ original returns for 2006 and 2007 were substantial, by
    comparison to the corrected amounts that the Lamprechts themselves
    reported on their amended returns.
    The Commissioner bears the burden of production with respect to
    the liability of an individual for any penalty. § 7491(c). To satisfy his
    burden, the Commissioner must present sufficient evidence to show that
    it is appropriate to impose the penalty in the absence of available
    defenses. See Higbee v. Commissioner, 
    116 T.C. 438
    , 446 (2001). Once
    the Commissioner meets his burden of production on penalties, the
    taxpayer must come forward with persuasive evidence that the
    Commissioner’s showing is incorrect. Rule 142(a); Higbee, 
    116 T.C. at 447
    .
    Compliance with the written supervisory approval requirement
    of section 6751(b)(1) is an element of the Commissioner’s burden of
    production on penalties. Graev v. Commissioner, 
    149 T.C. 485
    , 493
    (2017), supplementing and overruling in part 
    147 T.C. 460
     (2016).
    Section 6751(b)(1) provides:
    No penalty under this title [26 U.S.C.] shall be assessed
    unless the initial determination of such assessment is
    personally approved (in writing) by the immediate
    supervisor of the individual making such determination or
    such higher level official as the Secretary may designate.
    As the Tax Court has construed section 6751(b)(1), it requires written
    supervisory approval to be obtained before the IRS formally
    communicates to the taxpayer its determination that the taxpayer is
    liable for the penalty. Clay v. Commissioner, 
    152 T.C. 223
    , 249 (2019),
    aff’d, 
    990 F.3d 1296
     (11th Cir. 2021). 15 The IRS’s compliance with
    14 An “understatement” is defined as the excess of the amount of tax required
    to be shown on the return over the amount of tax which is shown on the return.
    § 6662(d)(2)(A).
    15  Formal communication of an IRS penalty determination implicating
    section 6751(b)(1) may come in any one of multiple forms. In Clay, 
    152 T.C. at 249
    , we
    14
    [*14] section 6751(b)(1) is appropriately considered in a deficiency case.
    See Graev, 
    149 T.C. at 493
    . And if, in so considering, we conclude that
    the IRS failed to secure written supervisory approval for a penalty
    subject to section 6751(b)(1), then we cannot sustain the penalty. See
    
    id.
    D.      Summons enforcement
    “For the purpose of ascertaining the correctness of any return . . .
    [or] determining the liability of any person for any internal revenue tax,”
    section 7602(a)(2) authorizes the Secretary of the Treasury (“the
    Secretary”), acting through the IRS, to summon
    any person having possession, custody, or care of books of
    account containing entries relating to the business of the
    person liable for tax . . . to appear before the Secretary at
    a time and place named in the summons and to produce
    such books, papers, records, or other data, and to give such
    testimony, under oath, as may be relevant or material to
    such inquiry.
    Where the summons identifies the person as to whose tax liability the
    information is sought, the IRS issues the summons without any court
    involvement. However, where the IRS needs information from a third
    party about the tax liability of a person whose identity it does not yet
    know, it may attempt to obtain that information from the third party by
    means of a “John Doe summons”, i.e., a summons “which does not
    held “that the initial determination for purposes of section 6751(b) was . . . when
    respondent issued the RAR [revenue agent’s report] to petitioners proposing
    adjustments including penalties and gave them the right to protest those proposed
    adjustments.” Written supervisory approval must precede the IRS’s initial formal
    communication of a penalty determination to an individual taxpayer, regardless of the
    means of communication. In considering supervisory approval of an assessable penalty
    under section 6707A, the Court of Appeals for the Ninth Circuit construed
    section 6751(b)(1) differently from the Tax Court, so that the burden on the IRS was
    less demanding. See Laidlaw’s Harley Davidson Sales, Inc. v. Commissioner, 
    29 F.4th 1066
    , 1070–1071, 1071 nn.4 & 5 (9th Cir. 2022) (rejecting this Court’s formal
    communication standard for the section 6707A penalty for failure to report
    participation in a listed transaction, and indicating that the initial determination in a
    deficiency case is likely embodied in the NOD), rev’g 
    154 T.C. 68
     (2020). Although this
    case is not appealable to the Ninth Circuit, see § 7482(b)(1), even if we applied the
    Ninth Circuit’s reasoning in Laidlaw’s the Commissioner would still meet his burden
    of production to show compliance with the supervisory approval requirement of
    section 6751(b)(1). We therefore have no occasion here to reconsider our opinions in
    Laidlaw’s or Clay.
    15
    [*15] identify the person with respect to whose liability the summons is
    issued.” § 7609(f). Before the Secretary can serve a John Doe summons,
    section 7609(f) requires him to establish the following in a court
    proceeding: 16
    (1) the summons relates to the investigation of a
    particular person or ascertainable group or class of
    persons,
    (2) there is a reasonable basis for believing that such
    person or group or class of persons may fail or may have
    failed to comply with any provision of any internal revenue
    law, and
    (3) the information sought to be obtained from the
    examination of the records or testimony (and the identity
    of the person or persons with respect to whose liability the
    summons is issued) is not readily available from other
    sources.
    Pursuant to section 7609(h)(1), “the United States district court for the
    district within which the person to be summoned resides or is found
    shall have jurisdiction to hear and determine any proceeding brought
    under subsection . . . (f) [regarding issuance of a John Doe summons].”
    That proceeding for approval of a John Doe summons is “ex parte”, and
    the court’s determinations are “made solely on the petition and
    supporting affidavits.” § 7609(h)(2).
    When a summons is served, the receiving party may sometimes
    voluntarily provide the requested information, and in that circumstance
    the summons will never be judicially enforced. But if the recipient does
    not produce the requested information, then section 7402(b) authorizes
    the United States to bring suit in the appropriate district court to
    enforce the summons, if necessary.
    E.      Statute of limitations for assessment of tax
    Section 6501(a) provides the general rule that “the amount of any
    tax imposed by this title [26 U.S.C.] shall be assessed within 3 years
    after the return was filed.” There is, however, an exception to this
    general 3-year rule in the case of substantial omissions from gross
    16 In such a proceeding, the Secretary is represented by the DOJ, pursuant to
    
    28 U.S.C. § 516
    .
    16
    [*16] income under section 6501(e)(1)(A).          For the purposes of
    section 6501(e)(1)(A), an omission from gross income is “substantial” if
    it is “in excess of 25% of the amount of gross income stated in the
    return”—the circumstance that the Lamprechts acknowledge exists
    here. Where there is a substantial omission from gross income,
    section 6501(e)(1)(A) provides that “the tax may be assessed . . . at any
    time within 6 years after the return was filed.” The parties agree that
    this 6-year period of limitation applies in this case.
    Additionally, section 7609(e) suspends the period of limitations
    for assessment of tax if a summons was issued but remains unresolved.
    Section 7609(e)(2) reads:
    (2) Suspension After 6 Months of Service of
    Summons.—In the absence of the resolution of the
    summoned party’s response to the summons, the running
    of any period of limitations under section 6501 . . . with
    respect to any person with respect to whose liability the
    summons is issued . . . shall be suspended for the period—
    (A) beginning on the date which is 6 months
    after the service of such summons, and
    (B) ending with the final resolution of such
    response.
    Accordingly, if the IRS serves a summons, and that summons is not
    resolved within six months of service, then the period of limitations for
    assessment under section 6501 is suspended from the six-month
    anniversary of service of the summons until its final resolution. (The
    parties disagree about whether such a suspension occurred in this case.)
    II.   Analysis
    The Lamprechts’ amended returns reported tax liabilities of
    $665,400 for 2006 and $2,031,194 for 2007, whereas their original
    returns reported tax liabilities of $43,929 for 2006 (understating the tax
    by $621,471) and $148,951 for 2007 (understating the tax by
    $1,882,243). Because the Lamprechts’ understatements of income tax
    on their original returns greatly exceed 10% of the tax required to be
    shown (i.e., the tax eventually reported on their amended returns), those
    understatements are “substantial” and are therefore subject to the
    accuracy-related penalty of section 6662(a) and (b)(2). See § 6662(d).
    Arithmetically speaking, the parties agree on the amounts of the
    17
    [*17] accuracy-related penalties for the 2006 and 2007 years as
    calculated by reference to the tax on the original returns. However, the
    Lamprechts dispute their liability on the grounds that we now discuss.
    A.     Written supervisory approval under section 6751(b)(1)
    Because the only liabilities at issue in this case are penalties, the
    Commissioner bears the burden of production. See § 7491(c). As we
    have noted, the Commissioner’s burden of production also includes the
    burden to show compliance with the requirement of section 6751(b)(1)
    that the “initial determination” of the penalty be approved in writing by
    the “immediate supervisor”.
    1.     The Commissioner’s showing
    The IRS first formally communicated its determinations of
    section 6662 accuracy-related penalties to the Lamprechts in the
    Letter 950, dated July 18, 2014, which included an examination report
    showing proposed changes to the Lamprechts’ 2006 and 2007 tax
    returns. (The Lamprechts do not point to any previous communication
    that     could   have     embodied     the    “initial   determination”.)
    Section 6751(b)(1) is satisfied where written supervisory approval of the
    “initial determination” of the penalty is obtained before the first formal
    communication of the penalty determination to the taxpayer. Clay,
    
    152 T.C. at 249
    . To show that such approval was obtained here, the
    Commissioner proffers Forms 5345–D, which state that the “Reason” for
    opening the Lamprechts’ 2006 and 2007 returns for examination was “to
    assess penalties on amended return that does not meet the qualified
    amended return criteria”, and that the “Follow-up Actions” would be to
    “Open up tax year” and “Assess accuracy penalty”—i.e., the section 6662
    accuracy-related penalty. (Emphasis added.) This form sufficiently
    identifies the penalty being determined, the reasoning for doing so, and
    the proposal that it is to be “assess[ed]”, thereby demonstrating an
    initial determination that the Lamprechts were liable for section 6662
    accuracy-related penalties for 2006 and 2007. The Forms 5345–D bear
    the immediate supervisors’ signatures, and they are dated February 12,
    2014 (for the 2007 approval), and April 10, 2014 (for the 2006 approval),
    which both predate the Letter 950 issued in July 2014. Because the
    Forms 5345–D reflect initial determinations of the Lamprechts’ liability
    for the section 6662 accuracy-related penalties for 2006 and 2007 and
    predate the first formal communication of the penalties to the
    Lamprechts, the Commissioner has met his burden of production to
    show compliance with section 6751(b)(1).
    18
    [*18]          2.      The Lamprechts’ criticisms
    The Lamprechts resist this conclusion with three criticisms that
    are not well grounded:
    a.      The nature of Form 5345–D
    First, the Lamprechts complain that Form 5345–D, which is used
    to open an examination, is not properly used for supervisory approval of
    a penalty. It is true that Internal Revenue Manual (“IRM”) 20.1.5.1.6(4)
    (Jan. 24, 2012) suggests that “written managerial approval . . . should
    be documented on the Civil Penalty Approval, leadsheet”; but three
    considerations must be kept in view: First, it is also true that in certain
    circumstances the IRM expressly stated that Form 5345–D is used to
    secure supervisory approval of certain penalties. 17 Second, “[i]t is a well-
    settled principle that the Internal Revenue Manual does not have the
    force of law, is not binding on the IRS, and confers no rights on
    taxpayers.” See, e.g., McGaughy v. Commissioner, 
    T.C. Memo. 2010-183
    ,
    
    100 T.C.M. (CCH) 144
    , 148. Third, we have held that no particular form
    is required for written supervisory approval under section 6751(b)(1).
    See, e.g., Palmolive Bldg. Invs., LLC v. Commissioner, 
    152 T.C. 75
    , 86
    (2019). The Commissioner made a showing that, for each year at issue,
    the form twice expressly requested approval to open an examination “to
    assess penalties on amended return” and to “[a]ssess accuracy penalty”.
    (Emphasis added.) The forms that the examining agent produced thus
    reflected not just a request to start an examination but rather his initial
    determinations to assess penalties, and those initial determinations
    were approved by the signatures of his supervisors before formal
    communication of those determinations to the Lamprechts. The
    Lamprechts raise no “genuine dispute” as to these facts.
    17 See, e.g., IRM 20.1.12.6(1) (Aug. 27, 2010) (“If the examiner determines a
    penalty [applicable to incorrect appraisals] is warranted, the examiner will prepare
    Form 5345–D . . . and secure the group manager’s approval”); IRM 4.32.2-12 (June 8,
    2012) (“Use Form 5345–D . . . to establish each tax year there will be a penalty
    assessed”); IRM 4.24.16.1.11 (Sept. 12, 2013) (establishing that supervisory approval
    of proposed penalties in excise tax examinations is given using Form 5345–D). The
    IRM is a sprawling instruction manual, the various parts of which are amended at
    different times, and its penalty-related provisions are scattered throughout. The
    year after these Forms 5345–D were signed, the IRM included an express provision
    that examiners “gain their manager’s approval to open a penalty case” (the action
    taken by Form 5345–D) “[a]fter [the] examiners determine that a penalty is
    warranted.” IRM 20.1.9.2.1(1) (July 8, 2015) (emphasis added).
    19
    [*19]              b.     The IRS’s handling of Form 5345–D
    Second, the Lamprechts question the sequence of events. They
    point out that electronic time-stamps of the digital signatures on the
    Forms 5345–D show that the supervisors signed the forms before the
    agent who made the initial determination of the penalty, and they
    contend that a “manager cannot approve an action which has not yet
    taken place.”        This scrutiny of the process is misdirected.
    Section 6751(b)(1) requires a signature from the supervisor approving
    the penalty, not from the individual making the initial determination.
    See Palmolive Bldg. Invs., LLC, 
    152 T.C. at 86
     (“The statute does not
    require any particular writing by the individual making the penalty
    determination, nor any signature or written name of that individual”).
    If the examiner signs the form at all (as to which section 6751(b)(1) is
    indifferent), it does not matter whether he does so before he submits the
    document to the supervisor or afterwards when he then moves the
    process along.
    c.     The Commissioner’s discovery responses
    Third, the Lamprechts argue that, even if these Forms 5345–D
    would otherwise satisfy the Commissioner’s burden of production under
    section 6751(b)(1), we should preclude the Commissioner from relying
    on these documents. The Forms 5345–D were first produced to the
    Lamprechts on February 12, 2021, when the Commissioner filed his
    motion for summary judgment. The Lamprechts say that he failed to
    produce them earlier in response to a discovery request or in response
    to our order ruling on their motion to compel production of documents,
    and they ask us therefore to preclude the Commissioner from relying on
    them now. This argument ostensibly implicates the important subjects
    of a litigant’s duty to respond conscientiously and honestly to his
    opponent’s discovery requests and the necessity of the Court’s enforcing
    its discovery rules and orders—with preclusive sanctions, where
    appropriate. However, the Lamprechts’ contentions do not fairly
    present the document request or our order on the motion to compel.
    i.     Document Request No. 7
    The document request that the Lamprechts rely on did not
    expressly request Forms 5345–D, nor did it more generally request
    documents to be relied on to show compliance with section 6751(b)(1) (a
    subject that the Lamprechts addressed in a roughly contemporaneous
    motion for summary judgment). Rather, Document Request No. 7
    20
    [*20] requested “[a]ll documents on which you intend to rely at trial.”
    However, because we will grant the Commissioner’s motion for
    summary judgment, there will be no trial in this case, and the set of
    documents to be “rel[ied on] at trial” will be an empty set.
    Moreover, Document Request No. 7 is very broad, difficult for
    even a conscientious recipient to respond to comprehensively when a
    case is not yet ready for trial. What a party will rely on at trial will
    depend on (among other things) what the party learns or obtains before
    that trial, what the parties will stipulate under Rule 91, what the party-
    opponent eventually disputes, and what the Court holds in pretrial
    orders. In the Tax Court, the final deadline to announce the exhibits to
    be offered at trial is provided in a Standing Pretrial Order (which was
    issued in this case on two previous occasions when trial dates were set
    but later continued) that gives a deadline for the pretrial exchange of all
    documents to be used at trial. Of course, a party is entitled to obtain
    documents, through discovery, ahead of that deadline; but discovery
    requests should seek specific information, rather than simply
    attempting to revise the Court’s schedule and move up the deadline for
    the disclosure of all trial exhibits.
    ii.    Motion to compel and order
    The Lamprechts invoke our order with the following contention:
    18.    By its order entered on September 26, 2017,
    the Court ordered Respondent to produce certain classes of
    documents requested by Petitioners and not previously
    produced by Respondent. The Court further stated “The
    Court would expect to preclude Respondent from relying at
    trial upon any responsive document not produced by
    October 13, 2017”. . . .
    ....
    20.   Respondent did not produce the Forms
    5345–D by October 13, 2017.
    21.    Respondent did not produce the Forms
    5345–D on or reasonably after February 20, 2018, the date
    on which he stated that he had written managerial
    approval for the substantial understatement penalty that
    satisfied the requirements of Section 6751(b)(1). . . .
    21
    [*21]        22.    Respondent    never     produced   the   Forms
    5345–D in discovery.
    23.    Consistent with the Order of the Court,
    Respondent should be precluded from relying upon the
    Forms 5345–D to prove compliance under Section 6751(b)
    because the documents were not produced by October 13,
    2017 or a reasonable time thereafter.
    It was not incorrect for the Lamprechts to say that we ordered
    production of “certain classes of documents”—but those classes did not
    include “[a]ll documents on which you intend to rely at trial” (their
    Request No. 7). Rather, we ordered
    that petitioners’ motion to compel production of documents
    is denied, except that it is granted . . . [as to certain
    documents requested in] Request No. 1 . . . . The Court
    would expect to preclude respondent from relying at trial
    upon any responsive document not produced by October 13,
    2017.
    That is, our order denied the Lamprechts’ motion to compel production
    of documents as to Request No. 7 (the request with which they allege
    the Commissioner failed to comply), and the preclusion (at trial) of which
    we warned related to the responsive documents that we did compel.
    Seeing no violation of our order, we will not preclude the Commissioner
    from relying on the Forms 5345–D to show compliance with
    section 6751(b)(1).
    Since there is no genuine dispute, for purposes of Rule 121(b),
    that the Commissioner has met his burden of production as to written
    supervisory approval, we turn to the Lamprechts’ other two contentions.
    B.    “Qualified amended returns”
    1.    Definition and effect
    A penalty-generating “substantial understatement” under
    section 6662(d)(1)(A) is determined by reference to “the amount of the
    tax imposed which is shown on the return”. § 6662(d)(2)(A)(ii). An
    amount not “shown on the return” may yield a penalty. The Lamprechts
    argue that we should look not to the amounts of tax shown (and not
    shown) on their original returns but rather to the amounts of tax shown
    on their amended returns for 2006 and 2007, which reported their entire
    22
    [*22] liabilities and reflected no understatements. The Lamprechts
    contend that these are “qualified amended returns” within the meaning
    of Treasury Regulation section 1.6664-2(c)(3) 18 and as such are the
    proper basis for reckoning whether there was an underpayment to which
    the section 6662 accuracy-related penalty may apply. Section 1.6664-
    2(c)(2) provides: “The amount shown as the tax by the taxpayer on his
    return includes an amount shown as additional tax on a qualified
    amended return (as defined in paragraph (c)(3) of this section)”; and if
    the Lamprechts’ amended returns are “qualified amended returns” as
    they contend, then they indeed made no “understatement” (under
    section 6662(b)(2)) that gave rise to an “underpayment” (under section
    6662(a)).
    The Commissioner contends that the amended returns were not
    “qualified amended returns” because they were filed after the issuance
    of the UBS John Doe summons. 19 He relies for this contention on
    Treasury Regulation section 1.6664-2(c)(3)(i), which defines a “qualified
    amended return” thus:
    A qualified amended return is an amended return . . . filed
    after the due date of the return for the taxable year
    (determined with regard to extensions of time to file) and
    before the earliest of–
    ....
    (D)(1) The date on which the IRS serves a
    summons described in section 7609(f) [i.e., a John
    Doe summons] relating to the tax liability of a
    person, group, or class that includes the taxpayer . . .
    with respect to an activity for which the taxpayer
    18Treasury Regulation section 1.6664-2(c) was a temporary regulation in 2006,
    see 
    Treas. Reg. § 1.6664
    -2T (2006), and was finalized on January 8, 2007, see T.D. 9309,
    2007-
    1 C.B. 497
    . The temporary and final versions contain the same text and are
    nearly identical in format. The final version is reproduced here.
    19 The Lamprechts “[a]ssum[e] for purposes of this argument that the UBS
    Summons was a valid and enforceable summons”, Doc. 163, para. 48; and they refer in
    a footnote, id. n.2, to their “discussion of whether the UBS Summons was a valid and
    enforceable summons” which is given in connection with the statute-of-limitations
    issue. We follow their lead and discuss the validity of the summons in the statute-of-
    limitations context. But if they mean to apply the invalidity argument to this
    “qualified amended return” issue also, then we reject that argument in this context for
    the reasons we discuss below in part II.C in the context of the statute of limitations.
    23
    [*23]        claimed any tax benefit on the return directly or
    indirectly.
    (2) The rule in paragraph (c)(3)(i)(D)(1) of this
    section applies to any return on which the taxpayer
    claimed a direct or indirect tax benefit from the type
    of activity that is the subject of the summons,
    regardless of whether the summons seeks the
    production of information for the taxable period
    covered by such return . . . .
    (Emphasis added.)
    In this case the IRS served the UBS John Doe summons on
    July 21, 2008, but the Lamprechts did not file their amended returns
    until December 2010—long after service of the summons. Therefore, if
    the UBS John Doe summons met the terms of subparagraph (3)(i)(D)(1),
    then the Lamprechts’ amended returns fail to qualify.
    2.     “[C]lass that includes the taxpayer”
    That UBS John Doe summons clearly “relat[ed] to the tax liability
    of a person, group, or class that includes the taxpayer”: It sought
    information regarding U.S. taxpayers with signature or other authority
    over accounts maintained at UBS in Switzerland for whom UBS did not
    have on file a Form W–9, “Request for Taxpayer Identification Number
    and Certification”, and did not issue Forms 1099 for tax years 2002
    through 2007. Consequently, the Lamprechts are clearly within the
    “class” of persons identified in the UBS John Doe summons because:
    (1) they were U.S. taxpayers; (2) Mr. Lamprecht maintained at UBS
    personal and business accounts over which he had signature authority;
    (3) unreported income was deposited into those accounts; and (4) the
    Lamprechts do not allege that UBS either had a Form W–9 on file for
    Mr. Lamprecht or issued to him a Form 1099 reporting income he
    received from UBS.
    3.     “[C]laimed any tax benefit”
    The Lamprechts argue, however, that they did not (in the words
    of subparagraph (3)(i)(D)(2) of the regulation) “claim[] a direct or
    indirect tax benefit from the type of activity that is the subject of the
    [UBS John Doe] summons”. According to the Lamprechts, in order to
    “claim[] a . . . tax benefit” one must make “some affirmative statement
    on the tax return that the taxpayer is entitled to the tax benefit claimed
    24
    [*24] [or] there must be some misstatement on the return itself that
    causes the understatement of tax liability.” The Lamprechts would have
    us distinguish “between a person who omits items or gains from his tax
    return and a person who claims a tax benefit on their tax return,” and
    would have us hold that a taxpayer who omits substantial items of gross
    income on his return does not thereby “claim[] a tax benefit”.
    In our view this argument for a narrow construction triggered
    only by an “affirmative statement” or “misstatement” is not supported
    by the text of the regulation nor by the caselaw and is not actually borne
    out in the facts of the Lamprechts’ returns.
    a.     The text of the regulation
    Treasury Regulation section 1.6664-2(c)(3)(i)(D)(1), as quoted
    above, establishes that, in order to be considered a “qualified amended
    return”, the amended return must be filed before “[t]he date on which
    the IRS serves a [John Doe] summons . . . relating to the tax liability of
    a . . . class that includes the taxpayer . . . with respect to an activity for
    which the taxpayer claimed any tax benefit on the return directly or
    indirectly.” Example 5 of Treasury Regulation section 1.6664-2(c)(5)
    shows the application of that principle and illustrates our issue. In
    Example 5, the IRS serves a section 7609(f) John Doe summons on a
    credit card company requesting the identities of, and information
    concerning, U.S. taxpayers who had signature authority over credit
    cards issued by, through, or on behalf of certain offshore financial
    institutions. The credit card company provides information about the
    taxpayer in response to the John Doe summons. The taxpayer files an
    amended return showing increased tax liability before the IRS contacts
    him concerning an examination of his income tax return, but after the
    John Doe summons had been served on the credit card company.
    Example 5 concludes that, “[u]nder paragraph (c)(3)(i)(D) of this section,
    the amended return is not a qualified amended return because it was
    not filed before the John Doe summons was served on [the credit card
    company].” In Example 5 the only difference described as having been
    reported on the amended return is “an increase in . . . Federal income
    tax liability”, so that the only “tax benefit . . . claimed” on the original
    return was (by implication) a lower income tax liability.
    Here, the UBS John Doe summons sought information about U.S.
    taxpayers who were underreporting gross income using foreign entities
    and offshore UBS accounts. The Lamprechts understated their gross
    income for 2006 and 2007 by omitting all foreign source income from
    25
    [*25] their tax returns, and accordingly they claimed a tax benefit,
    either directly by maintaining implicitly that they were entitled to the
    section 911 foreign earned income exclusion (discussed below), or
    indirectly by understating their tax liabilities and receiving tax savings
    through underpayments. Because the Lamprechts were members of the
    class of persons targeted by the UBS John Doe summons, claimed a tax
    benefit either directly or indirectly with respect to the activity identified
    in the UBS John Doe summons, and did not file their amended returns
    before the UBS John Doe summons was served, their amended returns
    for 2006 and 2007 are not “qualified amended returns”; and therefore,
    the reporting on those amended returns of the originally omitted income
    and the resulting additional tax does not result in that additional tax
    being included in the Lamprechts’ “amount shown as the tax” on their
    returns, for purposes of Treasury Regulation section 1.6664-2(c)(2) and
    section 6662 of the Code. Accordingly, the Lamprechts substantially
    understated their income tax for 2006 and 2007 and are liable for section
    6662 accuracy-related penalties. See § 6662(a), (d).
    U.S. taxpayers are subject to tax on world-wide income. See Huff
    v. Commissioner, 
    135 T.C. 222
    , 230 (2010) (quoting § 61) (“Gross income
    for the purpose of calculating taxable income is defined as ‘all income
    from whatever source derived.’”). Under section 7701(b)(1)(A)(i), a
    lawful permanent resident (such as the Lamprechts were in the years
    at issue) “shall be treated as a resident of the United States.” See also
    Cook v. Tait, 
    265 U.S. 47
    , 56 (1924). The Lamprechts omitted all foreign
    source income from their original 2006 and 2007 tax returns, thereby
    substantially understating their gross income and corresponding tax
    liabilities, and in doing so they received the benefit of understated tax
    liabilities. Furthermore, during the examination of their 2006 and 2007
    income tax returns, when the Lamprechts filed amended returns for
    2006 and 2007 to report foreign income previously unreported, their
    representative asserted that Mr. Lamprecht “did not report his foreign
    source income and earnings on his originally filed returns because he
    thought that ‘everything Swiss was not taxable in the U.S.’”
    There is such a thing as an “[e]xclusion from gross income”,
    provided in section 911, which excludes “foreign earned income”; but this
    exclusion—this tax benefit—is available only for a “qualified
    individual”, § 911(a), which is defined as someone whose tax home is in
    a foreign country, see § 911(d)(1), and Mr. Lamprecht was not such an
    individual in 2006 and 2007. One could say that the Lamprechts’
    omission of their foreign source income was an invalid claim of the
    foreign earned income exclusion under section 911—which amounts to
    26
    [*26] claiming a tax benefit whether affirmatively stated on the return
    or not. To properly claim such an exclusion, one would have to file with
    his income tax return a Form 2555, “Foreign Earned Income”, which the
    Lamprechts did not file. By their reckoning, apparently the taxpayer
    who erroneously excludes the earned income and files the Form 2555
    thereby makes a damning “affirmative statement” that constitutes the
    claiming of a benefit (so he is ineligible thereafter to fix the error on a
    “qualified amended return”); but the person who likewise erroneously
    excludes the earned income but obscures his omission by not reporting
    it on Form 2555 is deemed eligible to fix the error on a “qualified
    amended return” and thereby to avoid the penalty otherwise due on his
    understatement. If this were the rule, it would create a surprising and
    perverse incentive to hide one’s erroneous exclusions. We do not see that
    “affirmative statement” rule in the text of the regulation, which looks
    only to see whether the taxpayer “claimed any tax benefit on the
    [original] return directly or indirectly”.       
    Treas. Reg. § 1.6664
    -
    2(c)(3)(i)(D)(1) (emphasis added).
    b.     The caselaw
    As support for their argument that omitting items from a tax
    return is not the same thing as “claim[ing] any tax benefit,” the
    Lamprechts cite Colony, Inc. v. Commissioner, 
    357 U.S. 28
     (1958), and
    United States v. Home Concrete & Supply, LLC, 
    566 U.S. 478
     (2012). In
    Colony the Supreme Court held that understating gross income on an
    income tax return by misstating costs items or basis is not an “omi[ssion]
    from gross income [of] an amount properly includible therein” for the
    purposes of extending the period of limitations under section 275(c) of
    the 1939 Code (later reenacted as section 6501(e)(1)(A) in the
    1954 Code). Colony, Inc. v. Commissioner, 
    357 U.S. at
    36–37. The
    Supreme Court later extended the holding of Colony to
    section 6501(e)(1)(A) in Home Concrete & Supply LLC, 
    566 U.S. at 490
    .
    These cases both construe an “omi[ssion] from gross income” for the
    purposes of extending the period of limitations under section
    6501(e)(1)(A); they do not address (even tangentially) the question
    whether a taxpayer’s omissions from gross income constitute the
    “claim[ing of] any tax benefit on the return directly or indirectly” for the
    purposes of Treasury Regulation section 1.6664-2(c)(3)(i)(D).           The
    Lamprechts cite these cases for the proposition that “an omission from
    gross income [is] not the same as an overstatement of basis,” and with
    that we agree. Not every error in tax reporting is the same.
    27
    [*27] However, section 1.6664-2(c)(3)(i)(D) looks for a nonspecific “tax
    benefit”.      The holdings of Colony and Home Concrete that a
    misstatement of basis is not the same thing as an omission of income do
    not shed any light on how we should construe “claimed any tax benefit”;
    and we conclude that the broad reach obviously intended by the
    regulation—i.e., “any tax benefit” and “directly or indirectly”—tends
    against a narrow construction of “claimed any tax benefit”.
    Furthermore, in imputing an officer’s tax fraud to a corporation, the
    Court of Appeals for the Tenth Circuit in Ruidoso Racing Ass’n, Inc. v.
    Commissioner, 
    476 F.2d 502
    , 506 (10th Cir. 1973), aff’g in part,
    remanding in part 
    T.C. Memo. 1971-194
    , explained that “[a] tax benefit
    [to the corporation] could arise in two ways, understatement of income
    and overstatement of business expense deductions”, in concluding that
    a corporate officer’s “failure to report bar income reduced total income
    and, hence, produced a tax benefit for the corporation.” Ruidoso did not
    involve a “qualified amended return” analysis, but it illustrates in its
    different context the potential breadth of a “tax benefit”. We are
    satisfied that an understatement of income by omission claims a tax
    benefit within the meaning of Treasury Regulation section 1.6664-
    2(c)(3)(i)(D).
    c.   Affirmative statements on the Lamprechts’
    amended returns
    The Lamprechts’ position about the meaning of “claim[ing] any
    tax benefit” presumes a clean distinction between a mere omission of
    income and an affirmative claim of a tax benefit. The actual facts of the
    Lamprechts’ returns, however, do not bear out this distinction. As is
    often the case, the omission of income from the Lamprechts’ original
    returns affected other reporting on the returns and resulted in their
    originally claiming—affirmatively, one must say—deductions in
    amounts to which they were not entitled (and which they later had to
    reduce on their amended returns).
    As is shown on the table supra p. 9, the Lamprechts elected under
    section 63(e) to itemize deductions on their original and amended
    returns for both 2006 and 2007. The amount of itemized deductions that
    an individual may claim will be limited by section 68(a) if his “adjusted
    gross income [“AGI”] exceeds the applicable amount”. In 2006 that
    28
    [*28] applicable amount was $150,500; in 2007 it was $156,400. 20
    Where AGI exceeded those amounts, the greater one’s AGI, the greater
    was the limitation, resulting in increasingly reduced itemized
    deductions. On their original returns the Lamprechts incorrectly
    reported AGI of $1,073,652 for 2006 and $1,705,172 for 2007; but on
    their amended returns they correctly reported much larger AGI of
    $2,816,833 for 2006 and $6,930,169 for 2007. Consequently, the
    itemized deductions to which they were entitled were overstated on the
    original returns for 2006 as $187,338 and for 2007 as $202,497, and they
    were corrected on the amended returns to $152,481 for 2006 and
    $128,460 for 2007. That is, on their original returns they claimed
    excessive itemized deductions of $34,857 for 2006 and $74,037 for
    2007—totaling $108,894 for the two years.
    In sum, because the Lamprechts incorrectly failed to report on
    their original returns for 2006 and 2007 almost $7 million of their
    foreign income, those returns also claimed (one can say “affirmatively
    claimed”) itemized deductions totaling over $100,000 to which the
    Lamprechts were not entitled. If, as the Lamprechts argue, we must
    look for “some affirmative statement on the [original] tax return that
    the taxpayer is entitled to the tax benefit claimed”, we find such an
    “affirmative statement” on the Schedules A to their 2006 and 2007
    returns. The Lamprechts’ subsequent corrections on the amended
    returns were their admission that, because of the actual magnitude of
    their originally unreported income, they were not entitled to those
    greater amounts of deductions affirmatively claimed on the original
    returns. Therefore, even under the Lamprechts’ narrower construction
    of Treasury Regulation section 1.6664-2(c)(3)(i)(D)(2), their original
    returns “claimed a direct or indirect tax benefit from the type of activity
    that is the subject of the [UBS John Doe] summons”. As a result, the
    amended returns—not filed until after the John Doe summons—were
    not “qualified amended returns”; and we therefore look not to the
    amended returns but to the erroneous original returns to determine
    whether there were substantial understatements of “the amount[s] of
    tax imposed which [were] shown on the return[s]”. We hold that there
    was.
    20 See §§ 1(f)(3), 68(b)(2); IRS Pub. 501, “Exemptions, Standard Deduction, and
    Filing Information” at 1 (2006) (“Some of your itemized deductions may be limited if
    your adjusted gross income is more than $150,500”); IRS Pub. 501, “Exemptions,
    Standard Deduction, and Filing Information” at 1 (2007) (“$156,400”).
    29
    [*29] C.       The period of limitations and the UBS John Doe summons
    1.    The ordinary running of the six-year period of
    limitations
    The returns at issue here were deemed timely filed in April 2007
    and April 2008, and the parties agree that the six-year limitations
    period imposed by section 6501(e)(1)(A) applies. However, the NOD was
    not mailed until January 2015—i.e., more than six years after the filing
    of both of those returns. 21 The Lamprechts contend that assessment of
    the section 6662 accuracy-related penalties against them is barred by
    the statute of limitations for assessment under section 6501. The
    Commissioner contends that, under section 7609(e)(2), the running of
    the six-year limitations period was suspended by the service of the UBS
    John Doe summons, 22 and the Lamprechts argue that it was not.
    2.      The parties’ positions as to the UBS John Doe
    summons under section 7609(e)
    Because (as we explained above) the Lamprechts were members
    of the class of taxpayers identified in the UBS John Doe summons who
    participated in activities that were the subject of the summons, the
    Commissioner contends that, pursuant to section 7609(e), the service of
    the summons suspended the period of limitations for assessment once
    the summons had remained unresolved after 6 months from service.
    21 For 2006 (for which the return was deemed filed in April 2007) the six-year
    period would end in April 2013, which is 21 months short of the January 2015 issuance
    of the NOD. For 2007 (for which the return was deemed filed in April 2008) the six-
    year period would end in April 2014, which is nine months short of the January 2015
    issuance of the NOD. The Commissioner’s position requires that he show a suspension
    or extension of the period of limitations of no less than 21 months.
    22  The Commissioner has in fact three rejoinders to the Lamprechts’ statute-
    of-limitations contention, two of which we do not address here: (1) In his motion for
    summary judgment, the Commissioner asserts that the Lamprechts’ failure to file a
    Form 5741, “Information Return of U.S. Persons with Respect to Certain Foreign
    Corporations”, for an entity called Paro Inc. extended the period of limitations under
    section 6501(c)(8). Because we hold for the Commissioner on the section 7609(e)(2)
    issue, we need not reach section 6501(c)(8). (2) The Commissioner contends—but does
    not advance in his motion for summary judgment—that the period of limitations for
    assessment is open for the Lamprechts’ 2006 and 2007 years under section 6501(c)(1)
    because of fraudulent positions taken on their original returns. The Commissioner
    reserves this argument for trial should his motion for summary judgment be denied.
    The Lamprechts’ cross-motion asks us to hold that fraud is absent and does not extend
    the period; but since we hold for the Commissioner on other grounds, we need not reach
    this fraud issue.
    30
    [*30] The parties agree that the 6-month anniversary of service of the
    UBS John Doe summons is January 21, 2009, but they disagree as to
    the date of the final resolution of the summons. The Commissioner
    asserts that the UBS John Doe summons was not resolved until the IRS
    formally withdrew the summons almost 22 months later on November
    15, 2010. By that reckoning, 22 months is added to the limitations
    period, and the NOD is rendered timely as to both 2006 and 2007.
    The Lamprechts argue, first, that the UBS John Doe summons is
    invalid and unenforceable because it was issued for an improper purpose
    and therefore cannot operate to extend the period for assessment under
    section 7609(e). The Lamprechts also argue that final resolution of the
    UBS John Doe summons occurred not in November 2010 (when the IRS
    withdrew it) but rather on August 19, 2009, when the district court
    entered its order dismissing the summons enforcement case on the basis
    of the stipulation of dismissal filed by DOJ. By that reckoning, the
    service of the summons could have added only about 7 months to the
    limitations period, a suspension that would not render the NOD timely
    for either 2006 (which needed 21 months) or 2007 (which needed 9
    months). We now consider each of the Lamprechts’ two contentions.
    3.     Validity of the summons
    The Lamprechts contend that the John Doe summons did not toll,
    or suspend, the period of limitations because the summons lacked any
    valid purpose. Relying on the declaration of the “head of legal and
    international affairs of the Swiss Federal Banking Commission, a senior
    position in the Swiss Federal government”, the Lamprechts assert that
    “representatives of the Internal Revenue Service” stated that “the UBS
    Summons would be issued to interrupt the running of the statute of
    limitation” and admitted “that no enforcement activity for the UBS
    Summons would take place as long as discussions were underway
    between the United States and Switzerland relating to obtaining
    documents from UBS.” The Lamprechts observe that the documents
    that UBS did eventually produce were the result not of the summons
    but of a simultaneous request by the U.S. government pursuant to
    the tax treaty between the United States and Switzerland,
    and not unilateral measures such as the UBS
    Summons. . . . The IRS stated, however, that they would
    not withdraw the UBS Summons because the withdrawal
    would undo the extension of the statute of limitations that
    it wanted to achieve by issuing the UBS Summons as a
    31
    [*31] John Doe Summons. They also wanted to use the UBS
    Summons as leverage against Switzerland to ensure that
    UBS met its obligations under the UBS Settlement
    Agreement.
    According to the Lamprechts, issuing a John Doe summons solely
    to extend the period of limitations for assessment is an improper
    purpose which undermines its validity and vitiates any effect it might
    have had on the period of limitations. The Lamprechts cite United
    States v. Powell, 
    379 U.S. 48
    , 58 (1964), for the proposition that an
    improper purpose is “to harass the taxpayer or to put pressure on him
    to settle a collateral dispute,[23] or for any other purpose reflecting on
    the good faith of the particular investigation.”
    However, the Supreme Court’s opinion in Powell addressed a
    validity challenge by the summoned party in the district court summons
    enforcement proceeding, not by a class member in his own later tax case.
    The Lamprechts cite no authority for their doubtful propositions
    (1) that, after a district court has approved the validity of a John Doe
    summons for purposes of enforcement against a record-holder (here,
    UBS), the validity may later be challenged by a taxpayer in the John
    Doe class (here, the Lamprechts) in his own collateral proceeding, 24 nor
    (2) that a consequence of a successful challenge of invalidity by a
    member of the John Doe class would be that the summons would have
    no effect on the period of limitations. In the instant case, both UBS and
    the Swiss government were alert and well aware of the district court
    suit for enforcement of the summons, and there is no reason to suppose
    that they overlooked a colorable challenge to the validity of the summons
    at the time and that we therefore ought to remedy their oversight by
    entertaining such a challenge from a member of the John Doe class. But
    if we were to entertain that challenge here, we think that the
    Lamprechts have not made a showing to support the premise of their
    23 Because the summons at issue was a John Doe summons, it could not have
    been issued with an intention to harass in particular the Lamprechts (about whom the
    IRS was apparently ignorant) or to pressure them to settle any collateral dispute.
    Rather, the Lamprechts contend that the improper purpose in this instance was the
    extension of the period of limitations.

    469 U.S. 310
    , 321 (1985)
    (“[Section] 7609(f) provides no opportunity for the unnamed taxpayers to assert any
    ‘personal defenses,’ such as attorney-client or Fifth Amendment privileges that might
    be asserted under §[] 7609(a) and (b) . . . . What § 7609(f) does is to provide some
    guarantee that the information that the IRS seeks through a summons is relevant to
    a legitimate investigation, albeit that of an unknown taxpayer”).
    32
    [*32] challenge: They have not shown that the IRS’s sole purpose for
    the UBS John Doe summons was extending the period of limitations for
    assessment, nor that doing so was an improper purpose.
    The Lamprechts’ own characterization of the IRS’s purpose was
    two-fold: The IRS “wanted to achieve . . . the extension of the statute of
    limitations . . . by issuing the UBS Summons as a John Doe Summons.
    They [i.e., the IRS] also wanted to use the UBS Summons as leverage
    against Switzerland to ensure that UBS met its obligations under the
    UBS Settlement Agreement.” (Emphasis added.) The IRS had two
    potential means 25 to obtain information from UBS—i.e., the John Doe
    summons and the U.S.-Switzerland Agreement provisions—and it
    employed both. The extension of the period of limitations was one of the
    congressionally intended effects of the John Doe summons, and the IRS
    employed the John Doe summons in order to take advantage of that
    consequence, lest its investigation be rendered moot before it could be
    completed. But the IRS also (by the Lamprechts’ account) used the
    pendency of the summons as leverage to prompt Switzerland to
    cooperate with the production of information under the U.S.-
    Switzerland Agreement. The fact that the information was eventually
    produced pursuant to the U.S.-Switzerland Agreement is no indication
    that the John Doe summons was not helpful to that production and is
    no indication that the summons was not issued in good faith.
    The 2009 OVDP and the district court’s holding that the UBS
    John Doe summons satisfied the requirement of section 7609(f) indicate
    the good faith nature of the IRS’s investigation into U.S. taxpayers with
    unreported foreign income. Furthermore, the decision of the parties to
    the enforcement suit to leave the UBS John Doe summons open
    indicates that suspending the statutory period for assessment was not
    the sole purpose of the summons; rather, the IRS was evidently working
    to obtain information (and to maintain its ability to do so). In addition,
    leaving the UBS John Doe summons open was also obviously meant to
    assure compliance with the request for information specified in the U.S.-
    Switzerland Agreement, as is evidenced by the IRS’s eventual
    withdrawal of the summons after the information was obtained from
    25 Where the law grants two means, it is not inherently improper for a party to
    employ both means. For example, a taxpayer may sometimes properly pursue
    information from the IRS both through civil discovery in litigation and through a
    request under “FOIA”—the Freedom of Information Act, 
    5 U.S.C. § 552
    . Under FOIA
    he may avoid objections of irrelevance that might hinder discovery requests, but using
    FOIA to avoid a relevance dispute is not improper.

    [*33] UBS through the agreed channels. We see no impropriety in the
    UBS John Doe summons.
    We hold that the six-year statute of limitations for assessment
    under section 6501(e)(1)(A) was suspended by the operation of
    section 7609(e) because of the issuance of the UBS John Doe summons.
    4.      Final resolution
    Treasury Regulation section 301.7609-5(e)(3) 26 provides:
    For purposes of section 7609(e)(2)(B), final resolution with
    respect to a summoned party's response to a third-party
    summons occurs when the summons or any order enforcing
    any part of the summons is fully complied with and all
    appeals or requests for further review are disposed of, the
    period in which an appeal may be taken has expired or the
    period in which a request for further review may be made
    has expired.
    The Lamprechts contend that final resolution of the UBS John
    Doe summons occurred on August 19, 2009, when the district court
    ordered dismissal of the summons enforcement suit following entry of
    the stipulation of dismissal. (They suggest no alternative date.)
    However, the settlement agreement between the parties to the
    enforcement suit specified that dismissal of the suit would “in and of
    itself, have no effect on the UBS [John Doe] Summons or its
    enforceability” and contemplated compliance with the summons after
    dismissal of the suit through the method agreed to in the US-
    Switzerland Agreement. Because the UBS John Doe summons was not
    yet fully complied with at the time the enforcement suit was dismissed,
    that dismissal of the suit was not the final resolution of the summons.
    The Commissioner contends that final resolution of the UBS John
    Doe summons occurred when the IRS formally withdrew the summons
    on November 15, 2010, after receiving the requested records from UBS
    through the means agreed to in the U.S.-Switzerland Agreement. The
    Lamprechts do not assert (nor make any showing of) an earlier date by
    which UBS had “fully complied” with the summons and “all appeals or
    requests for review” had been “disposed of”. Accordingly, on the record
    before us, we hold that final resolution occurred upon withdrawal of the

    [*34] summons on November 15, 2010. Accordingly, the periods of
    limitation for assessment of tax for 2006 and 2007 were suspended by
    section 7609(e) from January 21, 2009, to November 15, 2010 (i.e., for
    664 days), and thereafter the periods of limitation for assessment of tax
    (as suspended) were set to expire on February 7, 2015 (for 2006), and
    February 7, 2016 (for 2007). Before those expiration dates, the IRS
    mailed the NOD to the Lamprechts on January 9, 2015, within the
    statutory period for assessment, and therefore assessment of the
    section 6662 accuracy-related penalties for 2006 and 2007 is not barred
    by the statute of limitations.
    III.   Conclusion
    Finding no genuine dispute of material fact, we will grant the
    Commissioner’s motion for summary judgment, will deny the
    Lamprechts’ motion for summary judgment, and will enter decision for
    the Commissioner as a matter of law.
    To reflect the foregoing,
    An appropriate order and decision will be entered.
