    Appeal from the United States District Court
    for the Northern District of Texas
    Before BENAVIDES, DENNIS, and SOUTHWICK, Circuit Judges.
    LESLIE H. SOUTHWICK, Circuit Judge:
    Bombardier Aerospace Corporation claims it is not required to remit
    federal excise tax on fees collected from participants in its fractional-aircraft-
    ownership program. The district court disagreed and ruled in favor of the
    Government on cross-motions for summary judgment. We AFFIRM.
    FACTS AND PROCEDURAL BACKGROUND
    During the successive quarterly tax periods in 2006 and 2007, which are
    the ones relevant here, Bombardier Aerospace Corporation operated a
    fractional-aircraft-ownership program called “Flexjet.” Flexjet participants
    bought fractional interests in aircraft, which provided them with on-demand
    access to a fleet of aircraft through a dry lease (i.e., the lease of a plane without
    Case: 15-10468     Document: 00513606497      Page: 2   Date Filed: 07/25/2016
    No. 15-10468
    a flight crew) exchange pool. Bombardier provided all of the management
    services necessary to support Flexjet. Such services included, but were not
    limited to, scheduling maintenance, securing insurance, staffing the aircraft
    with qualified pilots and crewmembers, and maintaining records required by
    the Federal Aviation Administration (“FAA”).
    In exchange for its services, Bombardier assessed three types of fees
    against Flexjet participants:
    • Monthly Management Fees (“MMFs”), or fixed charges covering costs
    associated with aircraft ownership regardless of whether the aircraft
    is flown (e.g., crew salaries, insurance, etc.);
    • Variable Rate Fees (“Variable Fees”), or variable charges covering
    costs associated with flight time (e.g., fuel, weather services,
    communications services, etc.); and
    • Fuel Component Adjustment (“Fuel Fees”), or charges covering fuel
    costs not otherwise included in the other fees (collectively, “fees”).
    Under 26 U.S.C. § 4261(a), any “amount paid for taxable transportation”
    is subject to federal excise tax. “Taxable transportation” includes travel by air
    meeting certain geographic requirements not at issue in this case. See 
    id. § 4262.
    During the relevant tax periods, Bombardier collected Section 4261
    tax on Variable Fees and Fuel Fees assessed against Flexjet participants, and
    remitted that tax to the IRS. It did not, however, remit tax on MMFs. The
    IRS audited Bombardier and assessed excise tax on MMFs collected during
    that time. Bombardier objected, arguing it was not subject to the tax during
    the 11 years prior to the relevant tax periods, even though it had undergone
    two IRS audits, and nothing had changed about its business or the law.
    In May 2012, unable to resolve the dispute administratively, Bombardier
    paid a portion of the MMFs assessment and filed this lawsuit. In its motion
    for summary judgment, Bombardier contended that, as a matter of law, it owed
    2

    No. 15-10468
    no Section 4261 excise tax on any of the fees collected. Because tax on Variable
    Fees and Fuel Fees had already been remitted, Bombardier sought a refund of
    taxes paid on those fees.
    The Government counterclaimed for the unpaid tax on MMFs, plus
    penalties, unassessed interest, and statutory additions. In its cross-motion for
    summary judgment, the Government also argued Bombardier lacked standing
    to bring its refund lawsuit for taxes paid on Variable Fees and Fuel Fees. The
    district court held that the IRS properly assessed tax on the fees, and that
    Bombardier had not met the statutory requirements to seek a refund for any
    overpayment on Variable Fees and Fuel Fees. Bombardier timely appealed.
    DISCUSSION
    We review issues of statutory interpretation and summary judgment de
    novo. In re Lively, 
    717 F.3d 406
    , 408 (5th Cir. 2013) (statutory interpretation);
    Kimbell v. United States, 
    371 F.3d 257
    , 260 (5th Cir. 2004) (summary
    judgment). Summary judgment is appropriate “if the movant shows that there
    is no genuine dispute as to any material fact and the movant is entitled to
    judgment as a matter of law.” FED. R. CIV. P. 56(a).
    I.    Statutory Requirements for a Refund Lawsuit
    Bombardier first seeks a refund for Section 4261 tax paid on Variable
    Fees and Fuel Fees it collected during the relevant tax periods because such
    fees are not “amount[s] paid for taxable transportation.” The district court
    dismissed the claim, however, concluding Bombardier had not met the
    statutory requirements to sue. 1 Under 26 U.S.C. § 6415(a), if a collecting entity
    1 The Government did not argue that Bombardier failed to meet the statutory
    requirements to sue related to the tax paid on MMFs because Bombardier bore the economic
    burden of that tax itself. See McGowan v. United States, 
    296 F.2d 252
    , 253–54 (5th Cir.
    3
    Case: 15-10468       Document: 00513606497          Page: 4     Date Filed: 07/25/2016
    No. 15-10468
    like Bombardier overpays on tax imposed by Section 4261, it may be entitled
    to a credit or refund if it “establishes . . . that [it] has repaid the amount of such
    tax to the person from whom [it was] collected . . . , or obtains the consent of
    such person to the allowance of such credit or refund.” 2
    Here, Bombardier does not contend that it has repaid any of the tax it
    collected on Variable Fees and Fuel Fees to Flexjet participants, or that it has
    obtained the consent of Flexjet participants to receive a refund.                   Instead,
    Bombardier argues none of that is a prerequisite to suit and can be fulfilled
    later in litigation. Bombardier relies largely on the text of Section 6415(a),
    which does not expressly state that a claimant must repay participants or
    obtain consents before it can file a lawsuit, and on two court opinions.
    Bombardier cites one decision where an employer sought a refund for
    the employee portion of an employment tax. Chicago Milwaukee Corp. v.
    United States, 
    40 F.3d 373
    , 374 (Fed. Cir. 1994). Before the lawsuit could be
    filed, a regulation-compliant administrative claim had to be submitted to the
    IRS. 
    Id. A Treasury
    Department regulation in effect at the time required the
    administrative claim to “include a statement that the employer has repaid the
    tax to such employee or has secured the written consent of such employee to
    allowance of the refund.” 
    Id. at 375
    (citing 26 C.F.R. § 31.6402(a)–2(a)(2)
    (1994)). The employer did not fulfill either requirement before pursuing its
    claim. 
    Id. The Federal
    Circuit, noting there was no timing requirement in the
    regulation, held the claim was not barred. 
    Id. at 375
    –76.
    1961). Bombardier did not collect those taxes from Flexjet participants and then remit them
    to the IRS; it paid a portion of the MMF taxes itself when it filed this lawsuit. See 26 U.S.C.
    § 4263(c) (imposing obligation to pay Section 4261 tax on carrier where tax is not paid at time
    transportation is made).
    2 The parties argue about whether this is a standing issue, but the district court
    construed it properly as a “straightforward question of statutory interpretation: whether
    [Bombardier] . . . met the requirements for bringing suit under.” See 26 U.S.C. § 6415(a).
    4
    Case: 15-10468       Document: 00513606497         Page: 5     Date Filed: 07/25/2016
    No. 15-10468
    Comparing Section 6415(a) to the Chicago Milwaukee regulation, a
    district court recently held that “compliance at any time before the refund
    issues” fulfills the purpose of the statute, i.e., “prevent[ing] a company from
    reaping a windfall by recovering taxes already passed on to its customers.”
    NetJets Large Aircraft, Inc. v. United States, 
    80 F. Supp. 3d 743
    , 752 (S.D. Ohio
    2015). Because Section 6415(a) does not state when these requirements must
    be satisfied, the NetJets court concluded that making the requirements a
    prerequisite to suit would “impose[] a harsh burden without good reason.” 
    Id. The NetJets
    case involved a Bombardier competitor that operated a fractional-
    aircraft-ownership program. 
    Id. at 751.
    Like Bombardier, the competitor
    denied liability for Section 4261 tax and did not repay fees collected or seek
    participants’ consent before filing its refund lawsuit. 
    Id. Other cases
    from the Federal Circuit analyzing Section 6415(a), though,
    undermine Bombardier’s dependence on Chicago Milwaukee. For example, the
    Federal Circuit’s predecessor 3 dismissed a Section 6415(a) refund claim where
    the claimant did not bear the economic burden of the tax itself, repay the tax
    to those from whom it was collected, or obtain consents. Epstein v. United
    States, 
    357 F.2d 928
    , 937–38 (Ct. Cl. 1966). The Court of Claims also had held
    that allowing a lawsuit to continue without first fulfilling the requirements
    would defeat the purpose of the statute “to preclude . . . unjust enrichment.”
    Gumpert v. United States, 
    296 F.2d 927
    , 928–29 (Ct. Cl. 1961).
    We agree with the district court, moreover, that Chicago Milwaukee is
    not especially analogous.         That case interprets a regulation that varies
    materially from Section 6415(a). While the Treasury regulation in Chicago
    Milwaukee merely requires a “statement” that the employer has repaid the tax
    3“Court of Claims cases, until overturned by [the Federal Circuit] en banc, are binding
    precedent . . . .” Bankers Trust N.Y. Corp. v. United States, 
    225 F.3d 1368
    , 1373 (Fed. Cir.
    2000).
    5
    Case: 15-10468      Document: 00513606497         Page: 6    Date Filed: 07/25/2016
    No. 15-10468
    or secured consents, the statute at issue here mandates that a claimant
    “establish” that it has fulfilled one of those two requirements. Compare 26
    C.F.R. § 31.6402(a)–2(a)(2) (1994) with 26 U.S.C. § 6415(a). We have held that
    the plain language of a statute controls, “reading it as a whole and mindful of
    the linguistic choices made by Congress.” In re Universal Seismic Assocs., Inc.,
    
    288 F.3d 205
    , 207 (5th Cir. 2002). We add that the Chicago Milwaukee dealt
    with requirements that must be met in filing an administrative claim that
    complies with regulations. 
    See 40 F.3d at 375
    . Here, the question is whether
    repayment or consents are statutory prerequisites to civil action. 4
    Furthermore, our own precedent aligns with the Federal Circuit’s
    interpretation of Section 6415(a). In one case, a district court had rejected a
    Section 6415(a) refund suit because the plaintiff “had not satisfied . . . the
    express [statutory] requirements . . . or the Court-made amelioration by
    showing” it had paid the tax itself. McGowan v. United States, 
    296 F.2d 252
    ,
    253 (5th Cir. 1961). We remanded for a new trial because the evidence was
    insufficient to sustain the district court’s finding that the plaintiff had not
    borne the economic burden of the tax. 
    Id. at 256.
    The district court on remand
    reiterated the prerequisites rule, noting that if “it is admitted that [the
    plaintiff] did not make the refund . . . or obtain consents” required by Section
    6415(a), “that ends the suit . . . .” McGowan v. United States, 
    222 F. Supp. 329
    ,
    330 (S.D. Fla. 1962). Without specifically addressing the prerequisites rule,
    we agreed with the district court’s ruling on a subsequent appeal. McGowan
    v. United States, 
    323 F.2d 655
    (5th Cir. 1963).
    In sum, the district court’s interpretation of Section 6415(a) is consistent
    4Bombardier also contends that Revenue Ruling 69-508, 1969-2 C.B. 262, 
    1969 WL 18851
    , requires that we find in its favor. Revenue Ruling 69-508, though, deals with whether
    the Section 6415(a) requirements are prerequisites to filing a timely administrative claim
    with the IRS, not a civil action.
    6

    No. 15-10468
    with the statute’s plain language and with authority from this and other
    circuits. This outcome does place an additional burden on entities already
    saddled with the responsibility of collecting the tax, but it also prevents unjust
    enrichment. It was proper for the district court to dismiss Bombardier’s refund
    claim.
    II.    Bombardier’s Tax Liability Under Section 4261
    Bombardier next asks us to conclude that because it is not engaged in
    “commercial aviation,” it is not liable for Section 4261 excise tax on any of the
    fees it collects from Flexjet participants. Alternately, Bombardier argues that
    MMFs, as fixed costs unrelated to actual air transportation, are not taxable
    under the statute. We examine these arguments in turn.
    A.    The Proper Test and Its Application
    The district court applied the IRS’s “possession, command, and control”
    test to determine that the fees at issue here are “amount[s] paid for taxable
    transportation.” See 26 U.S.C. § 4261(a). Bombardier’s argument on appeal
    focuses almost exclusively on attacking the test employed and not its
    application. Leaning mostly on legislative history, Bombardier asserts that
    the district court should have used the “commercial aviation” test.
    Bombardier traces its proposed test to a 1970 Congressional enactment.
    See Airport and Airway Revenue Act, Pub. L. No. 91-258, 84 Stat. 219 (1970)
    (“1970 Act”). Through the 1970 Act, Congress deemed an excise tax on the sale
    of aviation fuel that had previously applied to both commercial and
    noncommercial aviation applicable to noncommercial aviation only. 
    Id. At the
    time, “noncommercial aviation” was defined in the fuel tax statute, which is
    separate from Section 4261, as “any use of an aircraft, other than use in a
    business of transporting persons or property for compensation or hire by air.”
    7
    Case: 15-10468    Document: 00513606497     Page: 8   Date Filed: 07/25/2016
    No. 15-10468
    26 U.S.C. § 4041(c)(4) (1970) (current version found at 26 U.S.C. § 4083(b)
    (2004) (now defining “commercial aviation” instead of “noncommercial
    aviation” as “any use of an aircraft in a business of transporting persons or
    property for compensation or hire by air”)). Senate and House Reports on the
    1970 Act provided that, “[i]n general,” noncommercial aviation would be
    subject to fuel tax and commercial aviation would be subject to “tax[] on
    passenger and air freight transportation.” S. REP. NO. 91-706, 
    1970 WL 123227
    (1970); see also H.R. REP. NO. 91-601 (1970), as reprinted in 1970 U.S.C.C.A.N.
    3047, 3084.
    Bombardier contends that supporting its argument is a 2012 amendment
    to Section 4261 providing a three-year reprieve from excise tax to fractional-
    aircraft-ownership programs. See FAA Modernization and Reform Act of 2012,
    Pub. L. No. 112-95, 126 Stat. 11 (2012) (providing exemption from Section 4261
    tax until September 30, 2015) (“2012 Act”). One congressman commented that
    the 2012 Act “reaffirm[ed] that fractional aviation is non-commercial aviation”
    and thus should not be “subject to the commercial ticket tax.” 158 CONG. REC.
    H445-04, 
    2012 WL 339393
    (daily ed. Feb. 3, 2012) (statement of Rep. Tiberi).
    Taking all of this history together, Bombardier deduces that Congress meant
    to restrict Section 4261 tax to fees collected by entities involved in commercial
    aviation only.
    Bombardier asserts that the only circuit court opinion squarely
    addressing this issue to date supports application of the commercial aviation
    test. See Executive Jet Aviation, Inc. v. United States, 
    125 F.3d 1463
    (Fed. Cir.
    1997).   In Executive Jet, the question was whether fees collected by a
    corporation operating an aircraft management program similar to Flexjet were
    “amount[s] paid for taxable transportation” under Section 4261. 
    Id. at 1468–
    70. The lower court applied the possession, command, and control test, and
    held the fees to be taxable. Executive Jet Aviation, Inc. v. United States, No.
    8
    Case: 15-10468     Document: 00513606497      Page: 9   Date Filed: 07/25/2016
    No. 15-10468
    1:95-cv-00007-DGS, slip op. at 12–22 (Fed. Cl. Mar. 29, 1996). The Federal
    Circuit affirmed but examined only whether the corporation was engaged in
    commercial or noncommercial aviation. 
    125 F.3d 1463
    . Because of the extent
    of the corporation’s services, the court said it was in the “business of
    transporting persons . . . for hire by air”; thus, the fees were subject to Section
    4261 excise tax. 
    Id. at 1469.
          In applying the test to its own operations, Bombardier posits that
    because the FAA, the “federal agency tasked with regulating air travel,” has
    conclusively labeled Flexjet’s services as noncommercial, the fees collected are
    not taxable under Section 4261. Bombardier notes that its FAA license is
    noncommercial, that FAA regulations define “commercial” operations similarly
    to Section 4083(b) as transporting persons for “compensation or hire,” and that
    the FAA has determined fractional-aircraft-ownership “management” to be
    distinct from traditional commercial air operations. See, e.g., 14 C.F.R. §
    119.33(a); Regulation of Fractional Aircraft Ownership Programs and On-
    Demand Operations, 68 Fed. Reg. 54520-01, 
    2003 WL 22134765
    (Sept. 17,
    2003). As an example of this distinction, Bombardier points to the FAA’s
    acknowledgment of obvious business-model differences between a commercial
    airline, where the airline — not its passengers — owns the aircraft, and
    Flexjet, where the traveling participants are the owners. See 68 Fed. Reg.
    54520-01, 
    2003 WL 22134765
    .
    The district court, however, concluded that reliance on FAA regulations
    was misplaced. Quoting another recent decision that considered the same
    argument, the district court said there is no authority supporting the
    contention that the way safety regulations categorize Bombardier’s Flexjet
    operations “are ‘controlling’ or ‘applicable’ in a tax dispute.” See NetJets, 
    80 F. 9
        Case: 15-10468       Document: 00513606497          Page: 10     Date Filed: 07/25/2016
    No. 15-10468
    Supp. 3d at 755. 5 The FAA and IRS apparently agree in this regard. See 68
    Fed. Reg. 54520-01, 
    2003 WL 22134765
    (FAA final rule on fractional-aircraft-
    ownership programs providing that “[t]ax law does not govern safety rules”);
    Rev. Rul. 78-75, 1978-1 C.B. 340, 
    1978 WL 42060
    (IRS Revenue Ruling
    providing that “commercial” and “noncommercial” definitions in FAA
    regulations are “not consistent with” tax statutes).
    Rejecting the commercial aviation test, the district court instead
    determined Bombardier’s liability by applying the possession, command, and
    control test. Developed through a series of Revenue Rulings, that test focuses
    on whether the taxed entity, rather than the entity being transported, has
    “possession, command, and control” of the means of transportation and charges
    for its services. See IRS Tech. Adv. Mem. 2004-42-5048, 
    2004 WL 1369063
    (June 18, 2004) (“2004 TAM”) (summarizing pertinent Revenue Rulings);
    Davis v. United States, 
    495 U.S. 472
    , 484 (1990) (Revenue Rulings are given
    “considerable weight where they involve the contemporaneous construction of
    a statute and where they have been in long use.”). Stated another way, where
    a corporation or other entity merely acts as an aircraft owner’s agent by
    5In NetJets, corporations operating a successor to the aircraft management program
    in Executive Jet (NetJets) and a program offering similar services to owners of whole aircraft
    who allowed their aircraft to be used in a charter service for third-party customers (Executive
    Jet Management) claimed that neither model provided “taxable transportation” within the
    meaning of Section 
    4261. 80 F. Supp. 3d at 745
    –46. The corporations argued that the
    commercial aviation test applied, and that FAA regulations deem the businesses
    noncommercial which is dispositive of Section 4261 tax liability. 
    Id. at 753–56,
    761–64.
    As to NetJets, the court concluded that it was collaterally estopped by Executive Jet
    from holding the program did not provide taxable transportation. 
    Id. at 753–54.
    It allowed
    NetJets to avoid liability, though, as to the tax on the MMFs and Fuel Fees because a 1992
    Technical Advice Memorandum issued to NetJets’s predecessor was unclear about which fees
    were taxable; the IRS later conceded in negotiations with the corporation in Executive Jet
    that no tax was due on the MMFs or Fuel Fees. 
    Id. at 749–50.
    As to Executive Jet
    Management, the court applied the possession, command, and control test, to determine that
    a factual dispute existed over whether the program provided taxable transportation within
    the meaning of Section 4261 precluding summary judgment. 
    Id. at 761–62.

    providing limited operational and maintenance services, no tax is due. See IRS
    Tech. Adv. Mem. 2004-42-5048, 
    2004 WL 1369063
    . Where it acts as principal
    by providing a crew and insurance, and maintaining all operations and
    maintenance, among other services, it is providing taxable transportation
    under Section 4261. See 
    id. We agree
    that the possession, command, and control test is the proper
    framework under which to analyze an entity’s Section 4261 tax liability.
    Bombardier’s argument in support of the commercial aviation test fails for a
    number of reasons.
    As an initial matter, the definition of “commercial aviation” in Section
    4083(b), the current version of former Section 4041(c), explicitly applies only
    to the subpart of the Internal Revenue Code dealing with the specific fuel tax
    discussed in that subpart. See 26 U.S.C. § 4083(b). Section 4081(a)(2)(C) also
    makes clear that the fuel tax now applies to both commercial and
    noncommercial aviation, eroding Bombardier’s argument that the fuel tax
    applies only to noncommercial aviation and Section 4261 tax applies only to
    commercial aviation.
    Section 4261, moreover, has remained essentially unaltered since 1956. 6
    See Pub. L. No. 84-796, ch. 725, 70 Stat. 644 (1956). Thus, a statement in a
    congressional report related to the 1970 Act does not persuade us that former
    Section 4041(c)’s definition of “noncommercial aviation” (or current Section
    4083(b)’s    definition     of   “commercial    aviation”)      should   suddenly     be
    determinative of tax liability under Section 4261. See Central Bank of Denver,
    N.A. v. First Interstate Bank of Denver, N.A., 
    511 U.S. 164
    , 185 (1994) (“[T]he
    interpretation given by one Congress . . . to an earlier statute is of little

    changed over time.

    assistance in discerning the meaning of that statute.”). Congress, moreover,
    merely provided in the report that “in general” commercial operations would
    be subject to Section 4261 tax. See S. REP. NO. 91-706, 
    1970 WL 123227
    . The
    IRS has clarified that tax liability under Section 4261, whether the entity taxed
    is categorized as commercial or noncommercial under former Section 4041(c),
    is determined “on a flight-by-flight basis.” See Rev. Rul. 72-360, 1972-2 C.B.
    542, 
    1972 WL 30747
    . Thus, even an entity categorized as “noncommercial”
    under the fuel tax statute may incur tax liability under Section 4261 for some
    flights. See 
    id. We earlier
    mentioned that a congressman commented that the 2012 Act
    “reaffirm[ed] that fractional aviation is non-commercial aviation” and should
    not be “subject to the commercial ticket tax.” 158 CONG. REC. H445-04, 
    2012 WL 339393
    (daily ed. Feb. 3, 2012) (statement of Rep. Tiberi). With respect,
    statements by individual legislators do not reliably reveal “what a majority of
    both Houses of Congress intended when they voted for the statute.”           United
    States v. Ceballos-Torres, 
    218 F.3d 409
    , 414 n.6 (5th Cir. 2000). Furthermore,
    a conference report on the amendment in the 2012 Act expressly provided that
    “[n]o inference is intended” that beyond the three-year reprieve, fractional-
    aircraft-ownership programs are not providing taxable transportation within
    the meaning of Section 4261. See H.R. REP. NO. 112-381 (2012), at 280 n.32. 7
    We decline to draw the inference expressly prohibited by the report.
    Executive Jet is also of little assistance to Bombardier.         While it is
    unclear why the Federal Circuit declined to use the possession, command, and
    control test, the Government correctly notes that the appellate court did not
    hold that the lower court erred in its application of that framework. See
    7   This    report  is    available    at   https://www.gpo.gov/fdsys/pkg/CRPT-

    No. 15-10468
    Executive Jet, 
    125 F.3d 1463
    . Regardless, the decision is not binding on this
    court. It is notable, though, that the outcome in Executive Jet actually weakens
    Bombardier’s position in that the Federal Circuit determined that an aircraft
    management program with services very similar to those provided by
    Bombardier was a commercial operation providing “taxable transportation”
    within the meaning of Section 4261. 
    Id. at 1469.
          Additionally, we do not find merit in Bombardier’s assertion that the
    series of Revenue Rulings the IRS has relied on to refine the possession,
    command, and control test are “patchwork[ed]” and inconsistent, and therefore
    entitled to no deference. Revenue Rulings are the IRS’s “official interpretation”
    of tax law “published for the . . . guidance of taxpayers.”             26 C.F.R.
    § 601.601(d)(2)(i)(a). Where Revenue Rulings “have been in long use,” they are
    entitled to “considerable weight.” 
    Davis, 495 U.S. at 484
    .
    Because the law and its application to the real world is continually
    evolving, it is only natural that guidance in Revenue Rulings evolves too. We
    find a consistent theme, though, in the IRS’s guidance from the earliest
    Revenue Rulings grappling with this issue: where an entity is responsible for
    nearly every service and precondition necessary to transport persons in an
    aircraft, and it charges for those services, it is providing taxable transportation
    – even if the bona fide owner of the aircraft itself is the person traveling. For
    example, one ruling provides that there is no taxable transportation where a
    management company operates an aircraft and keeps it in good repair, but the
    owner retains control over crew and pays operating expenses. See Rev. Rul.
    58-215, 1958-1 C.B. 439, 
    1958 WL 10832
    ; see also Rev. Rul. 60-311, 1960-2 C.B.
    341, 
    1960 WL 12965
    (aircraft owner that leases to others but retains
    possession, command, and control of the aircraft is furnishing taxable
    transportation); Rev. Rul. 74-123, 1974 C.B. 318, 
    1974 WL 34732
    (management
    company operating aircraft owned by federal government providing taxable

    No. 15-10468
    transportation where its services are the same as when using its own aircraft).
    The district court did not err in applying the possession, command, and control
    test.
    Having determined the proper framework for our analysis, we turn to its
    application. Bombardier argues that the evidence in the record shows that it
    is an “agent” for Flexjet participants because participants own the aircraft,
    decide when and where to fly, and sign an FAA-required acknowledgement
    that they are in operational control.       Bombardier contends that it merely
    provides management services.
    The Government, though, presented evidence showing that Flexjet
    contractual agreements provide a leasehold or ownership interest in the
    aircraft to Bombardier during all flights, and allow Bombardier to take
    immediate possession of the aircraft at the time of the fractional interest sale.
    Bombardier arranges for the aircraft to be used, operated, inspected, serviced,
    and tested, and provides other services, such as hangar space and weather and
    communications services. Costs incurred in providing these services are paid,
    with some minor exceptions, by Bombardier. Additionally, Bombardier makes
    all necessary arrangements for flights, maintains all FAA records, furnishes
    pilots and crewmembers, and obtains risk and liability insurance (with
    Bombardier and the participants as insureds). Revenue Rulings teach us that
    ownership is not the determinative factor. See Rev. Rul. 74-123, 
    1974 WL 34732
    .
    Bombardier is in possession, command, and control of the means of
    transportation. Thus, it is required to submit Section 4261 tax on fees collected
    from Flexjet participants. The district court did not err in granting summary
    judgment for the Government.

    No. 15-10468
    B.    MMFs as “Amount[s] Paid for Taxable Transportation”
    Alternately, Bombardier posits that even if Variable Fees and Fuel Fees
    are subject to Section 4261 excise tax, MMFs (Monthly Management Fees)
    cannot be categorized as “amount[s] paid for taxable transportation.” See 26
    U.S.C. § 4261(a). Because the statute’s plain language anticipates taxing fees
    for actual transportation, Bombardier contends that fees going toward fixed
    costs incurred whether or not an aircraft is used are not taxable. Bombardier
    points to an IRS concession prior to the Executive Jet litigation that MMFs are
    not taxable under Section 4261. See 
    NetJets, 80 F. Supp. 3d at 749
    –50.
    This argument fails.    The MMFs must be paid in order for Flexjet
    participants to receive air transportation; therefore, the fees qualify as
    “amount[s] paid for taxable transportation.” Case law from other circuits and
    IRS Revenue Rulings support this conclusion. See generally, e.g., Shell Oil Co.
    v. United States, 
    607 F.2d 924
    , 926–27, 930 (Ct. Cl. 1979) (holding that monthly
    charges for fixed costs like insurance assessed by a helicopter-service company
    are taxable); Rev. Rul. 2006-52, 2006-2 C.B. 761, 
    2006 WL 2991235
    (Section
    4261 tax applies to an “airline’s costs associated with selling tickets” because
    such fees are “generally necessary to the air transportation” provided.).
    The IRS’s concession in the Executive Jet litigation, moreover, occurred
    20 years ago in a case that did not involve Bombardier. A Technical Advice
    Memorandum (“TAM”) issued to and relied on by the corporation in Executive
    Jet provided that “amounts paid to [the corporation] by aircraft owners for air
    transportation” are taxable under Section 4261. IRS Tech. Adv. Mem. 93-14-
    002, 
    1992 WL 465951
    (Apr. 9, 1993) (“1992 TAM”). The 1992 TAM did not,
    however, specify which fees are taxable. 
    Id. It is
    unclear from Executive Jet
    and NetJets why the IRS later agreed that no tax was due on MMFs in
    Executive Jet, but we will not rely on that concession in the face of other
    relevant authority providing that MMFs are not excepted from tax.            See
    15
    Case: 15-10468     Document: 00513606497          Page: 16     Date Filed: 07/25/2016
    No. 15-10468
    
    NetJets, 80 F. Supp. 3d at 749
    –50; Executive 
    Jet, 125 F.3d at 1467
    . The district
    court did not err in concluding that the fees collected by Bombardier, including
    the MMFs, are subject to Section 4261 excise tax.
    III.     Duty of Clarity/Unfair Competitive Disadvantage Principle
    Bombardier next contends that, regardless of its liability for Section
    4261 excise tax on the fees generally, the IRS is precluded by the “duty of
    clarity” and “unfair competitive disadvantage principle” from recovering
    unpaid tax on the MMFs and Fuel Fees collected during the relevant periods.
    A.    Duty of Clarity
    Bombardier primarily relies on a Supreme Court case and two decisions
    interpreting that case to support its “duty of clarity” argument. 8 The Supreme
    Court case involved an employer who reimbursed employees for lunch
    expenses while day-traveling on business. Central Ill. Pub. Serv. Co. v. United
    States, 
    435 U.S. 21
    , 21–22 (1978).                 The Government argued that the
    reimbursements constituted wages, thereby triggering the duty to withhold
    federal income tax. 
    Id. at 24–28.
    The Supreme Court disagreed, emphasizing
    the difference between primary and secondary tax liability: because an
    employer is secondarily liable, its “obligation to withhold [must] be precise and
    not speculative.” 9 
    Id. at 29,
    31–32. During the tax year in question, the Court
    said, there was no regulation or ruling requiring withholding on lunch
    The phrase “duty of clarity” is not found in Central Illinois, and we have not used it
    8
    in a tax context in any decision to date. We adopt Bombardier’s language here to avoid
    confusion.
    9 The Government argues on appeal that Central Illinois should be read narrowly to
    mean only that there is insufficient notice when “no taxpayer could have reasonably
    suspected that it would be obligated” to pay the tax. This argument, however, was not
    presented to the district court; thus, it is waived. See AG Acceptance Corp. v. Veigel, 
    564 F.3d 695
    , 700 (5th Cir. 2009).
    16
    Case: 15-10468    Document: 00513606497      Page: 17    Date Filed: 07/25/2016
    No. 15-10468
    reimbursements. 
    Id. at 32.
    Thus, “it [was] hardly reasonable to require [the]
    employer to fill the gap on its own account.” 
    Id. Similarly in
    a Claims Court case, an employer argued that it had no
    “clear and precise” notice of its duty to withhold taxes from per diem
    allowances paid to workers. General Elevator Corp. v. United States, 
    20 Cl. Ct. 345
    , 347, 352–53 (Cl. Ct. 1990). The Government disagreed, citing as sufficient
    notice an indefinitely suspended Revenue Ruling unrelated to the employer’s
    practices and two other “somewhat similar” rulings. 
    Id. at 353.
    The Claims
    Court, finding in the employer’s favor, said that a secondary tax collector “must
    have adequate notice [of] . . . what the IRS thinks the law is and therefore what
    actions” it must take. 
    Id. (quotation marks
    omitted) (citing Central 
    Illinois, 435 U.S. at 31
    –32). The court said the outdated and vaguely relevant Revenue
    Rulings created a “speculative gap” that made it unreasonable to hold the
    employer “to have received the degree of notice the law requires.” 
    Id. at 354.
          Most recently, the district court handling NetJets granted summary
    judgment in favor of one of the plaintiffs on duty-of-clarity grounds.         See
    NetJets Large Aircraft, Inc. v. United States, No. 2:11-cv-1023, 
    2015 WL 7784925
    (S.D. Ohio Nov. 12, 2015). The relevant plaintiff’s business model
    differs from Bombardier in that it provided management services for wholly-
    owned aircraft who allowed their aircraft to be used in a charter service for
    third-party customers.    
    Id. at *1.
       The court said that because no single
    Revenue Ruling sets forth the possession, command, and control test, and
    because the most factually relevant Revenue Ruling currently in effect
    provides that no tax is due, the IRS failed to provide that plaintiff with “precise
    and not speculative notice of [its] potential tax collection obligation under
    [Section] 4261.” 
    Id. at *9–11
    (citing Rev. Rul. 58-215, 
    1958 WL 10832
    ).
    Here, Bombardier contends that the IRS has taken conflicting positions
    about whether the MMFs collected by the fractional-aircraft-ownership
    17
    Case: 15-10468        Document: 00513606497          Page: 18     Date Filed: 07/25/2016
    No. 15-10468
    industry generally are taxable under Section 4261.                     This inconsistency,
    Bombardier argues, has created the kind of uncertainty not permitted by
    Central Illinois and General Elevator.
    For example, Bombardier again points to the 1992 TAM at issue in
    Executive Jet, which provided that the fees collected by the corporation in that
    case were subject to Section 4261 tax. IRS Tech. Adv. Mem. 93-14-002, 
    1992 WL 465951
    .        The 1992 TAM did not specify which fees collected by the
    corporation were taxable, though, and the IRS later told the corporation that
    it was not liable for unpaid tax on the MMFs. See 
    NetJets, 80 F. Supp. 3d at 749
    –50. Bombardier also argues that the IRS has stated in a Revenue Ruling
    that entities providing certain aircraft management services are not subject to
    Section 4261 tax, which is at odds with other agency pronouncements. See
    Rev. Rul. 58-215, 
    1958 WL 10832
    .               Finally, Bombardier contends that in
    guidance for examiners, the IRS admits that neither the Internal Revenue
    Code “nor any IRS published guidance specifically addresses” the taxability of
    fees collected by fractional-aircraft-ownership programs.                    See INTERNAL
    REVENUE SERV., AUDIT TECHNIQUE GUIDE: AIR TRANSPORTATION EXCISE TAX
    (2008). 10
    Bombardier also asserts that the IRS has been inconsistent in decisions
    and advice specific to its operations. In 1998, based upon the IRS’s concession
    in Executive Jet, Bombardier filed a refund claim for Section 4261 tax paid by
    Jet Solutions, Bombardier’s predecessor, on MMFs collected during tax periods
    in 1995 through 1997. The claim was initially denied, prompting a second
    10 Audit Technique Guides “help IRS examiners during audits by providing insight
    into issues and accounting methods unique to specific industries.” The guide Bombardier
    cites was located at https://www.irs.gov/Businesses/Small-Businesses-&-Self-Employed/Air-
    Transportation-Excise-Tax-ATG-Part-1#Fractional (last visited Apr. 14, 2016). The link on
    June 23, 2016 indicated that the IRS was “reviewing the content . . . and will make it available
    again as soon as possible.”
    18

    No. 15-10468
    audit of tax periods in 1998 through 2005 in which Bombardier had failed to
    collect and remit some of the tax. During the second audit, Bombardier and
    the IRS agreed to request technical advice to settle the issue of whether
    Bombardier owes Section 4261 tax on MMFs. See IRS Tech. Adv. Mem. 2004-
    42-5048, 
    2004 WL 1369063
    . The 2004 TAM issued by the IRS determined that
    Bombardier was liable because MMFs “paid . . . by aircraft owners are . . .
    amounts paid for taxable transportation under [Section] 4261.” 
    Id. Bombardier argues,
    however, that the 2004 TAM was revoked by
    subsequent agreements reached in the 1995-1997 and 1998-2005 audits
    absolving it of liability for those tax years. Citing an IRS memorandum,
    Bombardier said the agreements were the result of an appeals officer’s “legal
    conclusion that MMFs were not payments for taxable transportation.” Thus,
    Bombardier contends that the complaint filed in NetJets years after the
    relevant tax periods was the first notice it received that MMFs may be taxable
    under Section 4261. When the IRS failed to give “contemporaneous ‘precise
    and not speculative’ notice” of its secondary liability, Bombardier argues the
    IRS breached its duty of clarity.
    Granting summary judgment in the Government’s favor, the district
    court concluded that the 2004 TAM sufficiently apprised Bombardier of “what
    the IRS thought the law was and therefore what actions [Bombardier] was
    required to take.” See General 
    Elevator, 20 Ct. Cl. at 353
    . We agree. The 2004
    TAM was issued to Bombardier’s predecessor at Bombardier’s and the IRS’s
    request, and the advice clearly explained that MMFs are taxable under Section
    4261.     IRS Tech. Adv. Mem. 2004-42-5048, 
    2004 WL 1369063
    .                   This
    distinguishes the 2004 TAM from the 1992 TAM at issue in Executive Jet and
    NetJets, which is not applicable to Bombardier, as the 1992 TAM was not clear
    about which fees were taxable. Compare IRS Tech. Adv. Mem. 2004-42-5048,
    
    2004 WL 1369063
    with IRS Tech. Adv. Mem. 93-14-002, 
    1992 WL 465951

    No. 15-10468
    Bombardier’s revocation argument also is unpersuasive. The district
    court found that the 2004 TAM was never nullified because the IRS
    communicated to Bombardier that the audit agreements were the result of the
    unfair competitive disadvantage principle. Bombardier is correct, though, that
    the IRS only mentioned the principle in the March 2007 letter finalizing the
    agreement on the 1998-2005 audit. Bombardier focuses on the March 2006
    letter finalizing settlement related to the 1995-1997 audit. That letter did not
    mention the 2004 TAM, or cite the principle or any other reason why the IRS
    had agreed to forgo collecting tax for those years. When that letter was issued,
    Bombardier posits, the 2004 TAM was revoked.
    The IRS, however, has provided that a TAM is applied:
    [U]ntil it is withdrawn or until the conclusion is
    modified or revoked by a final decision in favor of the
    taxpayer with respect to that issue, the enactment of
    legislation, the ratification of a tax treaty, a decision
    of the United States Supreme Court, or the issuance of
    temporary regulations, final regulations, a revenue
    ruling, or other statement published in the Internal
    Revenue Bulletin.
    Rev. Proc. 2016-2, 2016-1 I.R.B. 102, 
    2016 WL 20934
    . A new TAM may also be
    requested to revoke earlier issued technical advice. 
    Id. We glean
    from this
    that a “final decision” resulting in a TAM’s revocation is in the form of an
    authoritative interpretation of tax law that applies to all taxpayers, like
    Supreme Court decisions or Revenue Rulings, or a definitive statement of the
    law that applies to a specific taxpayer requesting the information based on
    specific facts, like a Technical Advice Memorandum. See 
    id. A settlement
    agreement brokered with the IRS Appeals Office reducing a taxpayer’s liability
    as to certain tax periods is not enough to revoke a TAM. See 
    id. Here, Bombardier
    did not request a new TAM or Private Letter Ruling
    after the 2004 TAM was issued. Section 4261 was not amended in any relevant
    20
    Case: 15-10468    Document: 00513606497      Page: 21   Date Filed: 07/25/2016
    No. 15-10468
    way, the IRS’s published interpretation of the law did not change, and no
    Supreme Court decision was rendered. While a TAM is not precedential and
    does not bind us, see 26 U.S.C. § 6110(k)(3), it does bind the appeals officer and
    the taxpayer to whom it was issued, see 26 C.F.R. § 601.106(f)(9)(viii)(c) (effect
    of TAM). If the advice rendered is unfavorable to the taxpayer, though, the
    Appeals Office may settle that particular issue as if the TAM never existed.
    
    Id. § 601.106(f)(9)(viii)(c).
    Seemingly, that is exactly what occurred here. After
    the 2004 TAM clarified Bombardier’s tax responsibility, the Appeals Office
    exercised its discretion to settle the dispute over tax owed from 1995 to 2005
    as if the advice had never been given. Thus, it may have been reasonable for
    Bombardier to assume that it did not owe any tax in the periods to which the
    settlements related. It was not reasonable, though, for Bombardier to assume
    that the settlements revoked the TAM, a definitive expression of the
    application of Section 4261 to its operations. 
    Id. § 601.105(b)(5)(viii).
          As to the appeals officer’s conclusions, the Government explained in oral
    argument that prior to the 2004 TAM’s issuance, the officer “did in fact take
    the position that [MMFs] were not taxable.” After the 2004 TAM was issued,
    though, the Government posits that the officer’s theory of non-liability shifted
    to the unfair competitive disadvantage principle. Some deposition testimony
    from an appeals officer involved supports this recounting of events.
    Regardless, the opinion of an appeals officer as to Bombardier’s liability during
    specific tax periods does not undermine the effect of the 2004 TAM. See 26
    C.F.R. § 601.105(b)(5)(viii); see also Tucker v. Comm’r, 
    135 T.C. 114
    , 163 (2010)
    (Appeals officers have “adjudicative powers to conduct hearings and to issue
    determinations to resolve those hearings” but do not “possess the power to
    make final decisions for the IRS.”).
    We also do not find that the IRS has been meaningfully inconsistent.
    The 1992 TAM related to Executive Jet applied only to the corporation to which
    21
    Case: 15-10468    Document: 00513606497      Page: 22   Date Filed: 07/25/2016
    No. 15-10468
    it was issued. A “taxpayer may not rely on a TAM issued . . . for another
    taxpayer.” Rev. Proc. 2016-2, 
    2016 WL 20934
    . As previously discussed, the
    1992 TAM is distinguishable because it did not specify which fees were taxable
    under Section 4261. IRS Tech. Adv. Mem. 93-14-002, 
    1992 WL 465951
    . The
    2004 TAM is clear that the MMFs are subject to tax under that statute. IRS
    Tech. Adv. Mem. 2004-42-5048, 
    2004 WL 1369063
    .
    The 1958 Revenue Ruling cited by Bombardier, moreover, involved
    individual aircraft owners that were in greater operational control of their
    wholly-owned aircrafts than Flexjet participants’ control of the fractionally-
    owned aircrafts at issue here.      See Rev. Rul. 58-215, 
    1958 WL 10832
    .
    Regardless, this situation is not akin to Central Illinois and General Elevator.
    As the district court said, Bombardier was not “expected . . . to divine its tax
    collection obligations from such sources as a revenue ruling that had been
    suspended indefinitely.” Bombardier was provided notice of its responsibility
    in the 2004 TAM, which it requested to clarify its obligations.
    Finally, a statement in the Audit Technique Guide, general guidance
    issued to examiners, is unpersuasive. The statement is correct that there was
    no published guidance, in the form of a Revenue Ruling or otherwise, that
    specifically addressed the Section 4261 taxability of MMFs collected by
    fractional-aircraft-ownership program operators.       See AUDIT TECHNIQUE
    GUIDE: AIR TRANSPORTATION EXCISE TAX (2008). The issue here, though, is
    notice of a tax obligation, which the 2004 TAM provided to Bombardier. The
    district court correctly concluded that the summary judgment evidence
    supports a finding that Bombardier “was given notice of a precise and clear
    duty to collect” Section 4261 tax on the MMFs collected during the relevant
    periods. The IRS did not violate any duty of clarity it owed to Bombardier.

    No. 15-10468
    B.      Unfair Competitive Disadvantage Principle
    Bombardier also argues that the “unfair competitive disadvantage
    principle” 11 shields it from liability.          Bombardier cites a Court of Claims
    decision holding that the IRS abused its discretion in issuing conflicting
    rulings to competing taxpayers resulting in unequal tax treatment.
    International Business Machines Corp. v. United States, 
    343 F.2d 914
    , 919 (Ct.
    Cl. 1965). IBM and its competitor requested private letter rulings at the same
    time about the taxability of computer equipment. 
    Id. at 916–17.
    The IRS
    issued an unfavorable ruling to IBM and an erroneously favorable one to its
    competitor. 
    Id. Later, the
    IRS prospectively revoked the competitor’s ruling,
    which resulted in IBM paying more taxes over time. 
    Id. The court
    allowed
    IBM to recover taxes paid during the period that the conflicting rulings were
    in effect. 
    Id. at 925.
           Bombardier claims the IRS has been similarly inconsistent here, such as
    with an alleged IRS concession in litigation with competitor PlaneSense, Inc.,
    related to tax on MMFs and Fuel Fees. See generally Complaint, PlaneSense,
    Inc. v. United States, No. 1:11-CV-00136-PB (D.N.H. March 22, 2011), ECF No.
    1.   It also cites NetJets, where a district court held that a Bombardier
    competitor was not responsible for Section 4261 excise tax on MMFs or Fuel
    Fees because, as an Executive Jet successor, it relied on the 1992 TAM and an
    IRS concession that MMFs and Fuel Fees are not taxable. 
    See 80 F. Supp. 3d at 749
    –50, 756–59. Bombardier asserts that because NetJets holds a 75%
    market share, this outcome creates inequities within the industry.
    We, however, have construed the equitable rule articulated in the 1965
    11  We have referred to this principle as the “duty of consistency” or “equality doctrine.”
    See, e.g., Herrington v. C.I.R., 
    854 F.2d 755
    , 757 (5th Cir. 1988) (citing Bull v. United States,
    
    295 U.S. 247
    (1935)); Western Co. of N. Am. v. United States, 
    699 F.2d 264
    , 276–77 (5th Cir.
    1983). We again adopt Bombardier’s language for clarity’s sake.
    23
    Case: 15-10468       Document: 00513606497          Page: 24     Date Filed: 07/25/2016
    No. 15-10468
    Court of Claims IBM case narrowly. 12 One example concerns an equipment
    manufacturer who pointed out that a different manufacturer had secured a
    private letter ruling exempting it from certain excise taxes. Western Co. of N.
    Am. v. United States, 
    699 F.2d 264
    , 276 (5th Cir. 1983). Citing IBM, the
    company claimed the ruling should apply to it out of fairness, in part because
    the ruling had been on behalf of a company that manufactured trailers and
    chassis used in conjunction with the taxpayer’s own equipment.                      
    Id. We disagreed,
    as a claim of equal treatment required the company to seek its own
    ruling. 
    Id. “It is
    not enough that a private ruling has been issued to one
    similarly situated.” 
    Id. Unlike in
    IBM, we are not faced with dueling IRS rulings issued to
    competitors at the same time based on identical facts. The 1992 TAM, which
    applied only to the corporation in Executive Jet, was issued years before the
    tax periods relevant to this case. The 1992 TAM concluded, moreover, that
    “amounts paid . . . by aircraft owners for air transportation” are taxable under
    Section 4261. IRS Tech. Adv. Mem. 93-14-001, 
    1992 WL 465951
    . It failed to
    specify which fees were taxable. The IRS later agreed with Executive Jet that
    MMFs and Fuel Fees were excepted. See 
    NetJets, 80 F. Supp. 3d at 749
    –50.
    Bombardier’s reliance on NetJets is similarly misplaced. The equitable
    principle at issue in Western Company and IBM requires consistency by the
    IRS.    In NetJets, as in this litigation, the Government has argued that
    fractional-aircraft-ownership program operators owe Section 4261 tax on all
    collected fees. See 
    id. The IRS
    commenced an examination of the competitor
    corporations in NetJets around the same time it began auditing Bombardier.
    12Even the Federal Circuit has interpreted IBM narrowly in subsequent decisions.
    See Florida Power & Light Co. v. United States, 
    375 F.3d 1119
    , 1124 (Fed. Cir. 2004)
    (explaining that IBM is “limited to its facts,” and applies only when the plaintiff taxpayer
    also sought a private letter ruling that contradicts another taxpayer’s private letter ruling).
    24
    Case: 15-10468   Document: 00513606497     Page: 25   Date Filed: 07/25/2016
    No. 15-10468
    
    Id. at 751.
    Thus, the IRS has not treated NetJets more favorably than any
    other entity engaged in the fractional-aircraft-ownership industry. It was the
    district court that ruled in NetJets’s favor. See 
    id. at 749–50.
            As for PlaneSense, Bombardier directs us to one document in the record:
    a stipulation of dismissal of the case by the parties.        See Stipulation of
    Dismissal, PlaneSense, Inc. v. United States, No. 1:11-CV-00136-PB (D.N.H.
    July 26, 2013), ECF No. 25. It is unclear why those parties agreed to dismiss
    their claims, but Bombardier posits the IRS conceded that no tax was due on
    MMFs or Fuel Fees under Section 4261. The district court is correct that the
    scant evidence provided in relation to PlaneSense “would not permit a
    reasonable trier of fact to find that the IRS treated a similarly situated
    taxpayer more favorable than it treated [Bombardier] for the tax years in
    question.” The unfair competitive disadvantage principle has no application
    here. We affirm summary judgment in the Government’s favor.
    IV.     Motion for Leave to Amend Complaint
    Finally, Bombardier argues that the district court erred in denying its
    motion to supplement the complaint with more facts related to the unfair
    competitive disadvantage principle. Considering the late timing of the motion
    and that, as evidenced by our previous analysis, any amendment would be
    futile, the district court did not abuse its discretion in denying the motion. See
    FED. R. CIV. P. 16(b)(4) (requiring a showing of “good cause and . . . the judge’s
    consent” to amend after a scheduling order has been entered); S&W Enters.,
    L.L.C. v. SouthTrust Bank of Ala., NA, 
    315 F.3d 533
    , 535 (5th Cir. 2003).
    The district court decision is AFFIRMED.
