    UNITED STATES TAX COURT
    LAUREL ALTERMAN AND WILLIAM A. GIBSON, Petitioners v.
    COMMISSIONER OF INTERNAL REVENUE, Respondent
    Docket No. 13666-14.                         Filed June 13, 2018.
    Henry G. Wykowski and Matthew A. Williams, for petitioners.
    Cameron W. Carr, Kaelyn J. Romey, and Luke D. Ortner, for respondent.
    MEMORANDUM FINDINGS OF FACT AND OPINION
    MORRISON, Judge: The petitioners, Laurel Alterman and William A.
    Gibson, filed joint income-tax returns for 2010 and 2011. On March 13, 2014, the
    respondent (hereinafter, the “IRS”) issued a notice of deficiency to Alterman and
    Gibson. The notice of deficiency made adjustments to the income of a Colorado
    medical-marijuana business, owned by Alterman, income that was reported on
    -2-
    [*2] Schedules C, “Profit or Loss From Business”, of both returns. The IRS
    determined the following income-tax deficiencies and accuracy-related penalties
    under section 6662(a) for tax years 2010 and 2011.1
    Penalty
    Year           Deficiency           sec. 6662(a)
    2010           $157,821              $31,564
    2011            233,421               46,684
    Alterman and Gibson filed a petition under section 6213(a) for redetermination of
    the deficiencies for both years. We have jurisdiction under section 6214(a).2
    After taking into account concessions by the parties described later in the opinion,
    here are the issues remaining for decision:
    1.    What are the amounts of deductible business expenses for Alterman’s
    medical-marijuana business for tax years 2010 and 2011? We hold that
    petitioners are not entitled to any business-expense deductions. See infra
    Part I.
    1
    Unless otherwise indicated, all references to sections are to the Internal
    Revenue Code of 1986, as amended, and all references to Rules are to the Tax
    Court Rules of Practice and Procedure. All dollar amounts are rounded to the
    nearest dollar.
    2
    Alterman and Gibson resided in Colorado when they timely filed the
    petition. Therefore, any appeal of our decision in this case would go to the U.S.
    Court of Appeals for the Tenth Circuit unless the parties designate the Court of
    Appeals for another circuit. See sec. 7482(b)(1) and (2).
    -3-
    [*3] 2. Are Alterman and Gibson entitled to cost-of-goods-sold allowances for the
    medical-marijuana business in excess of the amounts conceded by the
    IRS in its briefs for tax years 2010 and 2011? The conceded amounts
    are $452,292 for 2010 and $232,772 for 2011. We hold that they are
    not entitled to additional allowances. See infra Part II.
    3.    Are Alterman and Gibson liable for accuracy-related penalties under section
    6662(a) for tax years 2010 and 2011? We hold that they are liable. See
    infra Part III.
    FINDINGS OF FACT
    The parties stipulated some facts, and those facts are incorporated by
    reference. At all times during 2009, 2010, and 2011 Alterman and Gibson were
    married and resided in Colorado. They filed joint returns for these years.
    Setting Up Altermeds, LLC
    During the years at issue, it was not illegal under Colorado law for people to
    use marijuana medically and for a medical-marijuana business to sell marijuana.
    See Colo. Const. art. XVIII, sec. 14. However, both activities were illegal under
    federal law.3 In July 2009, Alterman incorporated Altermeds, LLC.4 She was its
    3
    Under federal law, marijuana is classified as a Schedule I controlled
    substance under the Controlled Substances Act. Pub. L. No. 91-513, secs. 102,
    (continued...)
    -4-
    [*4] sole owner during 2009, 2010, and 2011. Altermeds, LLC, was a separate
    entity under Colorado law. For federal tax purposes, it is a disregarded entity,
    meaning that it is treated as a sole proprietorship of Alterman. See sec. 301.7701-
    2(a), Proced. & Admin. Regs.
    Operation of the Medical-Marijuana Dispensary
    Around September 2009, Altermeds, LLC, opened a retail store under the
    business name “Altermeds”. We refer to this retail store as the “dispensary”. The
    dispensary was in Louisville, Colorado, which is near Boulder, Colorado. The
    dispensary had regular operating hours of Monday through Saturday from 11 a.m.
    to 7 p.m., and on Sunday from 12 p.m. to 5 p.m.
    The dispensary sold smokable marijuana, either as prerolled marijuana
    cigarettes (i.e., joints) or as dried marijuana buds. It also sold marijuana in edible
    form, such as brownies and cakes, and orally-consumed tinctures5. We refer to
    3
    (...continued)
    202, 401, 84 Stat. at 1242, 1247, 1260 (1970) (codified as amended at 21 U.S.C.
    secs. 802, 812, 841 (2012)).
    4
    Before she started Altermeds, LLC, Alterman worked as a real estate agent.
    She continued to work as a real estate agent even while owning and working at
    Altermeds, LLC.
    5
    A marijuana tincture is a liquid containing marijuana and is consumed
    orally, for example, by adding tincture drops to tea.
    -5-
    [*5] Altermeds, LLC’s merchandise that contained marijuana, in any of the types
    of products mentioned above, as its “marijuana merchandise”.
    During 2010 and 2011, the dispensary also sold products that contained no
    marijuana, such as pipes, papers, and other items used to consume marijuana. We
    refer to this type of merchandise as the “non-marijuana merchandise”. In 2009,
    2010, and 2011 Altermeds, LLC, acquired all of its non-marijuana merchandise
    from third-party sellers.
    Altermeds, LLC, did not provide any services.
    Alterman shared the management responsibilities for the dispensary with
    her son, Jack Alterman. Jack worked at the dispensary during the years at issue. It
    was he who usually made the decisions concerning the purchase of marijuana and
    non-marijuana merchandise.6 Alterman was responsible for Altermeds, LLC’s
    recordkeeping and finances, such as making bank deposits, paying for
    merchandise, and paying expenses.
    6
    Jack did not work for Altermeds, LLC, continuously during the years at
    issue. The record is not clear when Jack was not working for Altermeds, LLC, and
    who handled merchandise purchases during his absence.
    -6-
    [*6] Purchases and Production of Marijuana Merchandise By Altermeds, LLC
    During 2009, Altermeds, LLC, did not grow or produce any of its marijuana
    merchandise. It bought all of its marijuana merchandise during that year
    exclusively from third parties.
    During 2010, Altermeds, LLC, continued to acquire marijuana merchandise
    from third-party sellers.
    Effective September 2010, Colorado required medical-marijuana businesses
    to grow at least 70% of the marijuana they sold. Colo. Rev. Stat. sec.
    12-43.3-103(b)(2) (2010). Anticipating this 70% requirement, Altermeds, LLC,
    began renting a warehouse in June 2010 to grow its own marijuana. The
    warehouse, which was in Boulder, was referred to as the “grow site”. When
    Altermeds, LLC, first rented the warehouse, the warehouse needed modifications
    before it could produce marijuana. Altermeds, LLC, hired Michael Boughton and
    Tiffany Weaver in June 2010 to make the necessary modifications. Boughton was
    a person who had previously sold marijuana merchandise to Altermeds, LLC. In
    September 2010, Altermeds, LLC, also hired Joseph Ingoglia to assist with the
    grow site. The only employees who worked at the grow site during 2010 were
    Boughton, Weaver, and Ingoglia.
    -7-
    [*7] While the grow site was being modified, Boughton and Weaver agreed to
    sell marijuana merchandise to Altermeds, LLC, on credit, pursuant to an oral
    agreement with Alterman. In 2010, marijuana was grown in tents in the
    warehouse while the grow site was being modified. The record is unclear as to
    whether the marijuana grown in the tents in 2010 was owned by Boughton and
    Weaver (who then sold it to Altermeds, LLC, on credit) or by Altermeds, LLC. It
    is also unclear whether any of the marijuana grown in the tents during 2010 was
    transferred to the dispensary in 2010.
    During 2010, Altermeds, LLC, made payments to Boughton, Weaver, and
    Ingoglia. The payments to Ingoglia were treated as wage payments by Altermeds,
    LLC. The payments to Boughton and Weaver included payments treated by
    Altermeds, LLC, for federal tax purposes as wage payments and included
    payments not so treated.
    In 2011, Altermeds, LLC, continued to purchase marijuana merchandise
    from third-party sellers. It is unclear whether Altermeds, LLC, purchased
    marijuana from Boughton and Weaver during 2011. From January until May
    2011, Altermeds, LLC, made payments to Boughton and Weaver. All of these
    payments were treated as wage payments for federal tax purposes by Altermeds,
    -8-
    [*8] LLC, although the record does not allow us to say how much of the payments
    were actually for Boughton’s and Weaver’s services as employees.
    Around May 2011, the Colorado Medical Marijuana Board certified that
    Altermeds, LLC’s grow site met the structural and mechanical requirements for
    marijuana cultivation facilities. Altermeds, LLC, fired Boughton and Weaver
    around the same time. Boughton and Weaver credibly testified that when they
    were fired, Altermeds, LLC, still owed them for marijuana that they had sold
    Altermeds, LLC, on credit. The record does not allow us to calculate the exact
    amount owed. Ingoglia continued to work at the grow site for some time after
    April 2011 but ended his employment with Altermeds, LLC, before the end of
    2011. After Ingoglia stopped working for Altermeds, LLC, it is unclear which
    Altermeds, LLC employees worked at the grow site.
    Employees of Altermeds, LLC
    In 2010 and 2011, Altermeds, LLC, employed Boughton, Weaver, Ingoglia,
    and others. The following table summarizes the Forms W-2, “Wage and Tax
    Statement”, issued by Altermeds, LLC, for the years at issue:
    -9-
    [*9]                Employee                  2011              2012
    Jack Alterman                 $10,800           $32,000
    Robert Des Plaines             33,620            48,450
    Samuel Feliciano               13,738             8,788
    Nathan Leake                   15,204            26,100

    Tiffany Weaver                  2,000            24,250
    Joseph Ingoglia                 2,800            25,000
    Chad Terry                        0               4,829
    Adam Locy                         0               8,745
    Jessica Cole                      0               9,466
    Laurel Alterman                   0              14,500
    Total                         95,186           232,358
    The record confirms that Altermeds, LLC, made payments in these amounts to
    these persons. The record does not allow us to say how much of these payments
    was actually for these persons’ services as employees. The overall amounts
    reported on the Forms W-2 as wages equal the wage deductions reported on
    Altermeds, LLC’s Schedules C: $95,186 in 2010 and $232,358 in 2011.
    Some employees worked at the dispensary, some worked at the grow site,
    and some worked at both. Employees at the dispensary sold marijuana
    merchandise and non-marijuana merchandise. According to Alterman, employees
    at the dispensary also engaged in the “trimming” of marijuana. “Trimming” is the
    process of removing stems, seeds, and twigs from a marijuana plant to convert
    - 10 -
    [*10] marijuana to final, salable form. Alterman estimated that of the time spent
    by any particular employee at the dispensary, 40% of that time was occupied by
    trimming. We do not believe that employees working at the dispensary spent
    substantial time trimming because (1) no evidence other than Alterman’s
    testimony supports the assertion that employees working at the dispensary
    trimmed marijuana and (2) other witnesses credibly testified that no trimming took
    place at the dispensary.
    Neither Altermeds, LLC employees nor Alterman recorded the hours
    worked by particular employees at the grow site versus the dispensary. Given the
    lack of information in the record, we cannot determine what part of the payments
    treated by Altermeds, LLC, as employee wages was paid for work performed at
    the grow site versus the dispensary.
    Records of Altermeds, LLC
    During examination, Alterman provided the IRS with receipts that
    corroborated some of the expenses paid by Altermeds, LLC, and some of the
    purchases of merchandise made by Altermeds, LLC.7 None of these receipts are in
    the record.
    7
    The record does not reveal whether the receipts for purchases of
    merchandise given by Alterman to the IRS were receipts for non-marijuana
    merchandise or marijuana merchandise or both.
    - 11 -
    [*11] The record contains Altermeds, LLC’s general ledger for 2010 and 2011.
    We first discuss the notations made in the general ledger for purchases of
    marijuana and non-marijuana merchandise. We refer to these notations as
    “purchase notations”. For each purchase of merchandise, the general ledger
    recorded (1) the date, (2) the dollar amount, and (3) the method of payment. Each
    purchase of merchandise was given one of four types of descriptions in the general
    ledger: (1) smokable, for marijuana buds and pre-rolled joints; (2) edible, for food
    items, tinctures, and other infused items; (3) non-marijuana, for papers and other
    paraphernalia; and (4) a fourth grouping mysteriously labeled “Meds-C”
    (hereinafter, the “undefined merchandise”). The record is unclear as to whether
    the undefined merchandise contained marijuana. Sometimes the identity of the
    seller was noted in the purchase notation; sometimes it was not. The general
    ledger aggregated the total amounts paid for merchandise purchases in a year in
    each of the four descriptive categories of merchandise. The general ledger also
    aggregated the total amounts paid for all merchandise purchases in a year.
    The general ledger tracked the dispensary’s daily receipts in the same four
    merchandise categories as the purchase notations. The general ledger does not
    reflect the dollar amount of each particular transaction. According to the gross
    receipts in the 2010 general ledger, Altermeds, LLC, derived 86.5% of its gross
    - 12 -
    [*12] receipts from smokable marijuana merchandise, 8.6% from edible marijuana
    merchandise, 1.4% from non-marijuana merchandise, and 3.6% from the
    undefined merchandise. For 2011, the percentages are 81.7% from smokable
    marijuana merchandise, 14.2% from edible marijuana merchandise, 3.6% from
    non-marijuana merchandise, and 0.6% from the undefined merchandise.
    We now discuss the notations made in the general ledger with respect to
    expenses (as distinguished from the purchase of merchandise). For each payment
    of an expense, the general ledger shows (1) the date, (2) the dollar amount, (3) the
    type of expense (e.g., utilities, rent, etc.), (4) the payment method (i.e., cash,
    check, credit card, or electronic funds transfer), and (5) sometimes, the identity of
    the payee.
    Altermeds, LLC, paid its expenses, and paid for its merchandise, through
    various alternative methods: (1) checks from three checking accounts written
    directly to vendors, (2) checks from one of three checking accounts (i.e., the
    dispensary account, as described below) to Jack, who then paid cash to the vendor,
    (3) electronic funds transfers from the three checking accounts, (4) a Visa credit
    card, (5) cash paid out of the cash register at the dispensary, or (6) cash paid from
    an unknown source.
    As discussed above, checks were written from three checking accounts.
    - 13 -
    [*13] The first checking account was often used to pay the expenses of the
    dispensary and for merchandise purchases. We refer to this checking account as
    the dispensary account. Checks were written from this account during both 2010
    and 2011. The record contains check-register entries for the checks written during
    2010. The record contains check-register entries for some, but not all, of the
    checks written during 2011. The information in each check-register entry included
    the date and the amount of the check. For checks written for merchandise
    purchases, the check-register entries also sometimes showed the payees. For
    checks written for smokable marijuana, the check-register entries also sometimes
    showed the strains and weights of marijuana purchased. For checks written for
    edibles and non-marijuana merchandise, the check-register entries also sometimes
    showed the quantities purchased. For checks written to pay expenses (as
    distinguished from the purchases of merchandise), the check-register entries also
    showed the general purposes of the payments (e.g., “Costco - supplies”), and
    sometimes showed the payees.
    The second checking account was often used to pay the costs of the grow
    site and also for merchandise purchases. We refer to this second checking account
    as the grow-site account. Although checks were written from this account in 2010
    and 2011, there is no check register in the record for this account.
    - 14 -
    [*14] The third checking account was first used in December 2011. It was
    sometimes used to pay expenses and also for merchandise purchases. No check
    register is in the record for this account.
    In both years at issue, some merchandise purchases and expenses were paid
    with electronic funds transfers, made from all three checking accounts.
    The record contains banks statements for all three checking accounts. For
    the dispensary account, the bank statements cover January 2010 to December
    2011. For the grow-site account, the bank statements cover the period from when
    the account was opened, June 2010, until December 2011. For the third account,
    the bank statements cover December 2011, which is when the account was first
    used. The bank statements contain entries corresponding to all checks written
    from the three accounts during 2010 and 2011. The bank statements contain
    entries corresponding to all electronic funds transfers from all three accounts
    during 2010 and 2011.
    For electronic funds transfers, the bank statements show the date of each
    transfer, the amount of the transfer, and the payee. This set of information is not
    more detailed than the corresponding information in the general ledger for the
    identical electronic funds transfers. A number of entries recorded in the 2011
    general ledger as purchases of smokable marijuana merchandise were paid with
    - 15 -
    [*15] electronic funds transfers. For some of these entries, the payees were home
    improvement stores, such as Home Depot or Lowe’s. We find it improbable that
    these stores sold smokable marijuana to Altermeds, LLC.
    In both years at issue, some merchandise purchases were made with cash
    taken from the dispensary’s register. Altermeds, LLC, kept a daily sales record for
    its dispensary. In addition to recording gross receipts (on a daily basis), this daily
    sales record noted the amount of cash taken from the register for merchandise
    purchases and classified the purchased merchandise into one of the four
    merchandise categories. Occasionally additional details concerning the purchased
    merchandise were recorded on the daily sales record.8
    Some edible marijuana merchandise was purchased during 2011 using cash.
    The source of the cash is unclear.
    Some merchandise was purchased during 2010 by Jack, using cash that he
    acquired when Alterman wrote a check to him. Merchandise was purchased in
    this way when the third-party seller did not wish to receive a check. It appears
    8
    The additional information for these merchandise purchases was no greater
    in detail than what Alterman noted in the most detailed check-register entries for
    purchases of merchandise (i.e., those check-register entries in which Alterman
    noted the strains and weights for smokable marijuana merchandise, and the unit
    quantities for edible marijuana and non-marijuana merchandise).
    - 16 -
    [*16] that the checks used in such an intermediary purchase were drawn from the
    dispensary account and were recorded in the check register.
    In 2010 and 2011, Altermeds, LLC, used a Visa credit card to pay some of
    its expenses and for merchandise purchases. The credit card statements
    (hereinafter, the “Visa statements”) in the record were incomplete, as pages were
    missing for both years. Alterman wrote on the Visa statements descriptions of the
    categories of some of the expenses. Either Alterman or Mark Pendleton,
    Altermeds, LLC’s bookkeeper, went through the Visa statements and aggregated
    certain expenses or merchandise purchases into single sums. These sums were
    then transferred to the general ledger. Thus, for these sums, the general ledger
    entries are not specific to particular payments, but rather a group of payments.
    Pendleton used Alterman’s initial categorizations of Visa card charges when he
    transferred the amounts to the expense or merchandise purchase categories in the
    general ledger.
    As discussed above, the dispensary used daily sales records that tracked its
    gross receipts. Alterman gave the daily sales records to Pendleton to enter into the
    general ledger. Pendleton used the daily sales records to prepare monthly
    statements, but these monthly statements are not in the record. To prepare the
    general ledger, Pendleton relied on documents that Alterman provided to him,
    - 17 -
    [*17] including daily sales records, Visa statements, and receipts. (It is unclear
    whether Alterman provided Pendleton with bank statements. It appears that
    Alterman did provide Pendleton with some deposit slips, i.e., records given to
    Alterman by the bank when Alterman made a particular deposit. However, no
    deposits slips are in the record.) Alterman herself did not verify whether the gross
    receipts in the general ledger were consistent with the amounts stated in the daily
    sales records.
    Tax Reporting
    The income of Altermeds, LLC, was reported on Schedules C attached to
    Alterman and Gibson’s 2010 and 2011 joint returns.
    For 2010, the Schedule C reported gross receipts of $894,922. The
    Schedule C reduced gross receipts by cost of goods sold of $464,119. The
    Schedule C also reported business-expense deductions of $385,489.
    For 2011, the Schedule C reported gross receipts of $657,126. The
    Schedule C reduced gross receipts by cost of goods sold of $253,089. The
    Schedule C also reported business-expense deductions of $384,817.
    The Schedules C reported that cost of goods sold for each year at issue (and
    2009) was computed as follows:

    The Schedules C reported that Altermeds, LLC’s income had been calculated
    using the cash method of accounting.
    For the 2009 tax year, the first year that Altermeds, LLC, was in business,
    Alterman and Gibson’s tax return was prepared by Pendleton.9 Pendleton also
    served as Altermeds, LLC’s bookkeeper during 2009. Pendleton had been
    preparing returns for Alterman and Gibson in years before 2009.
    For the 2010 tax year, Alterman decided instead to use the services of
    Comiskey & Co. (hereinafter, “Comiskey”) to prepare the return.10 Comiskey was
    recommended to Alterman by Jill Lameroux, another medical-marijuana business
    owner. Alterman reviewed the 2010 return before signing it.
    9
    Pendleton attached a separate Schedule C for tax year 2009 to report the
    expenses and income of Alterman’s real estate agent business.
    10
    Comiskey attached a separate Schedule C for tax year 2010 to report the
    expenses and income of Alterman’s real estate agent business.
    - 19 -
    [*19] For Comiskey’s use in preparing the 2010 return, Alterman provided the
    firm with a profit and loss statement and a balance sheet for Altermeds, LLC.11
    She did not provide Comiskey with other records, such as the general ledger or
    receipts. Comiskey apparently used the profit and loss statement and the balance
    sheet to report the various items of cost of goods sold on the Schedule C for
    2010.12 In particular:
    !      $464,119 Total Cost of Goods Sold for 2010. It appears that
    Comiskey transferred the profit and loss statement entry “Total Cost
    of Goods Sold”, in the amount of $464,119, to the 2010 Schedule C
    line item for cost of goods sold, in the same amount. The entry “Total
    Cost of Goods Sold” in the profit and loss statement, in the amount of
    $464,119, was composed of four subtotals for each of the four
    merchandise categories used in the purchase notations in the general
    ledger. The record does not reveal how the profit and loss statement
    computed the subtotals in each of the four merchandise categories.
    11
    The record does not reveal who prepared the profit and loss statement or
    the balance sheet or what information was used to prepare these two documents.
    12
    The record includes the profit and loss statement and balance sheet for tax
    year 2010. No such documents appear in the record for tax years 2009 and 2011,
    and we believe there were no such documents for those years.
    - 20 -
    [*20] !   $0 Beginning Inventory for 2010. It is unclear how Comiskey
    determined the $0 value reported on the 2010 Schedule C for
    beginning inventory. The balance sheet for 2010 reflects only one
    inventory amount, “Total Inventory”, which is presumably the ending
    inventory for 2010. (As explained below, this amount was composed
    of subtotals.)
    !    $12,279 Ending Inventory for 2010. It appears that Comiskey
    transferred the entry in the balance sheet, “Total Inventory”, in the
    amount of $12,279, to the 2010 Schedule C line item for inventory at
    the end of the year, in the same amount. The entry “Total Inventory”
    in the balance sheet, in the amount of $12,279, was composed of
    three subtotals for smokable marijuana ($9,592), edible marijuana
    ($1,275), and non-marijuana merchandise ($1,412). It further appears
    that the balance sheet entry of $12,279 for “Total Inventory”
    corresponds to the same named entry, with the same dollar amount, in
    the 2010 general ledger (to which Comiskey did not have access).
    The 2010 general ledger entry “Total Inventory” was made up of five
    subtotals: smokable marijuana of $9,592; edible marijuana of $1,275;
    non-marijuana merchandise of $1,412; undefined merchandise of $0;
    - 21 -
    [*21]        and another category, “Inventory - Other”, of $0. We are unable to
    trace the documentary source for the $12,279 amount, or its subtotals,
    found in both the general ledger and the balance sheet. It appears that
    these amounts ultimately came from an yearend inventory done by
    Alterman, who testified that she generally performed a physical
    inventory at the end of each year and documented her inventory count
    on paper.13 The record does not reveal whether Alterman assigned
    cost values to the unit quantities in the physical inventory; even if she
    did so, the record does not give us any information about the cost she
    assigned to any particular unit in inventory or how she assigned cost
    to any particular unit for any unit of purchased marijuana and non-
    marijuana merchandise or self-grown marijuana merchandise. Indeed
    the record does not have any physical inventory that Alterman
    committed to paper.
    !    $476,398 Purchase Costs for 2010. The record is unclear as to how
    the $476,398 amount on the 2010 Schedule C for purchase costs of
    13
    A physical inventory is a list of the types of products on hand and unit
    quantities of each type of product at a given time.
    - 22 -
    [*22]         merchandise was computed.14 We note that the aggregated sum of
    “Total Inventory” ($12,279) from the balance sheet and “Total Cost
    of Goods Sold” ($464,119) from the profit and loss statement equals
    the dollar amount for purchase costs of merchandise on the 2010
    Schedule C ($476,398).
    For the 2011 return, Alterman decided to have Pendleton prepare the return
    instead of Comiskey.15 Alterman’s decision to go back to Pendleton was
    motivated by the fact that Comiskey had charged Alterman significantly more for
    preparing the 2010 return than Pendleton had charged for the 2009 return. Also
    Pendleton told Alterman he had experience preparing returns for other medical-
    marijuana businesses. After Pendleton prepared the 2011 return, Alterman
    reviewed it. During 2011, Pendleton continued to work as Altermeds, LLC’s
    bookkeeper (as he had during 2010, even though he had not prepared the 2010
    return). As part of his bookkeeping duties for 2011, he continued to prepare
    monthly statements from documentation Alterman provided to him. He also
    14
    The 2010 general ledger contains a line item (“Total Cost of Goods Sold”)
    that appears analogous to the tax-return line item under which the $476,398
    amount appears. However, the general-ledger item is a different amount,
    $473,485.

    Pendleton attached a separate Schedule C for tax year 2011 to report the
    expenses and income of Alterman’s real estate agent business.

    [*23] created the 2011 general ledger. The 2011 general ledger bizarrely recorded
    that “Total Inventory” was $12,279, which was the same dollar amount recorded
    in the “Total Inventory” entry in the 2010 ledger. The 2011 general ledger also
    showed five subtotals. The 2011 general ledger’s description of each subtotal, and
    the dollar amount of each subtotal, were the same as in the 2010 general ledger.
    We are uncertain why the 2011 Schedule C reported $0 as the beginning
    and ending inventories for 2011. That would mean, implausibly, that Altermeds,
    LLC, had no merchandise on hand at the beginning and end of 2011. As for the
    $253,089 reported on the 2011 Schedule C for purchase costs, we are unsure
    where this amount came from. The analogous entry in the 2011 general ledger
    recorded the amount as $217,089.
    Audit and Statutory Notice of Deficiency
    In 2012, the IRS examined Alterman and Gibson’s 2010 and 2011 returns.
    It focused exclusively on Altermeds, LLC’s Schedules C. Revenue Agent Kelly
    Tipton (hereinafter, “RA Tipton”) was the principal revenue agent who examined
    the returns. Alterman provided RA Tipton with documents, such as receipts and
    daily sales records.
    The notice of deficiency determined that Altermeds, LLC, underreported
    gross receipts by $24,663 and $8,359 for 2010 and 2011, respectively. The notice
    - 24 -
    [*24] allowed costs of goods sold of $388,231 and $1,021 for tax years 2010 and
    2011, respectively. Furthermore, the notice disallowed all of Altermeds, LLC’s
    Schedule C business-expense deductions for tax years 2010 and 2011 on section
    280E grounds, except for depreciation and section 179 expenses in the amounts of
    $49,671 and $719 for tax years 2010 and 2011, respectively.
    The notice also determined accuracy-related penalties under section
    6662(a). RA Tipton made the initial determination to impose accuracy-related
    penalties. The determination was approved by RA Tipton’s supervisor, Tommy D.
    McDonald. Both the initial determination and the approval of the initial
    determination were made before the notice of deficiency was mailed.
    Conceded Issues
    In the petition, Gibson sought innocent-spouse relief from joint and several
    liability for the deficiencies and penalties in the notice of deficiency. At trial,
    Gibson conceded his claim for innocent-spouse relief for both years at issue. At
    trial, Alterman and Gibson conceded that Altermeds, LLC, underreported its gross
    receipts in the amounts stated in the notice of deficiency.
    In the IRS’s brief, the IRS increased the amounts of cost of goods sold it
    conceded for 2010 from $388,231 in the notice of deficiency to $452,292 and for
    2011 from $1,021 to $232,772. The IRS’s brief stated that, for tax year 2010, the
    - 25 -
    [*25] amount conceded in excess of the cost-of-goods-sold allowance in the notice
    of deficiency was made up of the following: $9,580 for rent for the grow site;
    $2,010 for utilities at the grow site; $49,671 for depreciation and section 179
    expenses (the same amount allowed as a deduction in the notice); and $2,800 for
    wages.16 The IRS’s brief stated that, for tax year 2011, the amount conceded in
    excess of the cost-of-goods-sold allowance in the notice of deficiency was made
    up of the following: $22,407 for rent for the grow site; $10,207 for utilities at the
    grow site; $719 for depreciation and section 179 expenses (the same amount
    allowed as a deduction in the notice); $25,000 for wages; $295 for testing of
    marijuana; and $173,123 for purchases of merchandise.17
    OPINION
    The taxpayer bears the burden of proving, by a preponderance of the
    evidence, that the IRS’s determinations in the notice of deficiency are incorrect.
    See Rule 142(a); Welch v. Helvering, 
    290 U.S. 111
    , 115 (1933); Estate of Gilford
    v. Commissioner, 
    88 T.C. 38
    , 51 (1987). This is the burden of persuasion.
    Alterman and Gibson concede that they have the burden of persuasion. With
    16
    The sum of these amounts ($9,580 + $2,010 + $49,671 + $2,800) and
    $388,231 is $452,292.
    17
    The sum of these amounts ($22,407 + $10,207 + $719 + $25,000 + $295 +
    $173,123) and $1,021 is $232,772.
    - 26 -
    [*26] respect to certain issues involving liability for penalties, the IRS has the
    burden of production. This is described in greater detail infra Part III.
    I.    Business-Expense Deductions
    Section 162 allows a deduction for the expenses of carrying on a business.
    Sections 167 and 179 allow deductions for depreciation of assets used in a
    business. Section 280E, however, provides that no deduction is allowed for an
    amount paid or incurred in carrying on a business if the business consists of
    trafficking in controlled substances. Although Alterman and Gibson concede that
    Altermeds, LLC, trafficked in controlled substances, they contend that it had a
    separate business of selling non-marijuana merchandise and that the business-
    expense deductions of this separate business are not disallowed by section 280E.
    Whether selling non-marijuana merchandise was a separate business from selling
    marijuana merchandise is an issue of fact that depends on, among other things, the
    degree of economic interrelationship between the two activities. See Californians
    Helping to Alleviate Med. Problems, Inc. v. Commissioner (CHAMP), 
    128 T.C. 173
    , 183 (2007). Under the circumstances, we hold that selling non-marijuana
    merchandise was not separate from the business of selling marijuana merchandise.
    First, Altermeds, LLC, derived almost all of its revenue from marijuana
    merchandise. Second, the types of non-marijuana products that it sold (pipes and
    - 27 -
    [*27] other marijuana paraphernalia) complemented its efforts to sell marijuana.18
    Altermeds, LLC, had only one unitary business, selling marijuana. See Canna
    Care, Inc. v. Commissioner, 
    T.C. Memo. 2015-206
    , at *12, aff’d, 694 F. App’x
    570 (9th Cir. 2017).
    If, however, selling non-marijuana merchandise were considered a separate
    business, then the expenses of that business would be deductible. See CHAMP,
    
    128 T.C. at 183
    -185 (stating that caregiving services were a business separate
    from provision of marijuana; expenses of providing caregiving services were
    deductible). Alterman and Gibson argue that these deductible expense are
    $54,707.03 in 2010 and $57,517.93 in 2011. These amounts are equal to 40% of a
    list of subtotals in a table in the brief filed by Alterman and Gibson after trial.
    Each subtotal bears a vague description, for example “Non-COGS Utilities”.
    18
    Besides marijuana paraphernalia, Alterman testified that the dispensary
    also sold (1) hats and T-shirts with the name and business logo of Altermeds,
    LLC, (2) magazines about marijuana, (3) and chicken soup. No documentary
    evidence corroborates the existence or extent of these sales. On a preponderance
    of evidence, we find that no such items were sold. Furthermore, these types of
    products as described by Alterman would generally complement the sales of
    marijuana by the dispensary. For example, the hats and T-shirts as described by
    Alterman bore the name and business logo of Altermeds, LLC. Thus, even if
    Altermeds, LLC, sold such hats and T-shirts, selling those items would have
    helped advertise medical marijuana.
    - 28 -
    [*28] However, the brief fails to adequately explain why any portion of those
    subtotals is deductible. In particular the brief fails to:
    !      identify any specific payments that make up these subtotals;
    !      provide record citations to support these subtotals; and
    !      propose findings of facts regarding these subtotals.
    Alterman and Gibson’s argument regarding the amounts of business-expense
    deductions attributable to a putative second business was not briefed properly.
    See Rule 151(e)(3) (brief must include proposed findings of fact with references to
    the record); Rule 151(e)(5) (brief must include arguments regarding any disputed
    questions of fact). Even if we thought that the sale of non-marijuana merchandise
    was a separate business, Alterman and Gibson’s failure to properly brief the
    amount of deductions that would be attributable to this business would preclude us
    from allowing any deductions for the separate business.19
    We now consider whether Alterman and Gibson are entitled to any
    business-expense deductions for Altermeds, LLC, apart from the amounts of
    19
    Although, under the rule in Cohan v. Commissioner, 
    39 F.2d 540
    , 543-544
    (2d Cir. 1930), the Court can estimate the amount of deductible expenses if there
    is a reasonable basis for making such an estimate, Alterman and Gibson do not
    contend the Court should employ the Cohan rule to estimate the business expenses
    of the putative second business. Furthermore, their brief fails to point to any
    evidence that would provide the reasonable basis required for the Court to make
    an estimate under the Cohan rule.
    - 29 -
    [*29] business-expense deductions allegedly attributable to the putative second
    business. Because we consider Altermeds, LLC’s business to consist of
    trafficking in controlled substances, all such deductions are disallowed by section
    280E. Furthermore, Alterman and Gibson, having failed to properly brief their
    entitlement to deductions for business expenses they claim relate to Altermeds,
    LLC’s putative second business, have also failed to properly brief their entitlement
    to deductions for any other business expenses of Altermeds, LLC. They did not
    even allege the amounts of such deductions, much less any specific payments,
    provide record citations, or propose findings of fact. Therefore, we conclude
    Alterman and Gibson are not entitled to any business-expense deductions for
    Altermeds, LLC.20
    20
    This conclusion holds even for depreciation and sec. 179 expenses.
    Alterman and Gibson claimed deductions of $119,639 for 2010 and $11,739 for
    2011 for depreciation and sec. 179 expenses and, as discussed above, the notice of
    deficiency partially allowed deductions for depreciation and sec. 179 expenses
    ($49,671 and $719 for 2010 and 2011, respectively). In their post-trial brief,
    Alterman and Gibson argue that they are entitled to deduct business expenses for a
    second business that did not consist of trafficking in controlled substances, but
    they do not identify among these business expenses any depreciation and sec. 179
    expenses. Furthermore, they argue that the deductions they claimed for
    depreciation and sec. 179 expenses on their Schedules C for 2010 and 2011 should
    be recharacterized as allowances for cost of goods sold of Altermeds, LLC, in its
    business of trafficking in controlled substances. The IRS argues in its post-trial
    brief that sec. 280E disallows all business-expense deductions (including
    depreciation and sec. 179 expenses) for Altermeds, LLC. Furthermore, it
    (continued...)
    - 30 -
    [*30] II.     Cost of Goods Sold
    Alterman and Gibson argue they are entitled to cost-of-goods-sold
    allowances in excess of the amounts the IRS conceded in its briefs. The individual
    income tax is computed on the basis of taxable income. Sec. 1. Taxable income is
    equal to gross income minus deductions. Sec. 63. Cost of goods sold is a
    reduction made in the course of computing gross income. Sec. 1.61-3(a), Income
    Tax Regs. It is not a deduction, see Max Sobel Wholesale Liquors v.
    Commissioner, 
    69 T.C. 477
     (1977), aff’d, 
    630 F.2d 670
     (9th Cir. 1980), and
    therefore it is not disallowed by section 280E, Olive v. Commissioner, 
    139 T.C. 19
    , 32 (2012), aff’d, 
    792 F.3d 1146
     (9th Cir. 2015); sec. 1.162-1(a), Income Tax
    Regs.
    As the taxpayers, Alterman and Gibson must prove the amounts allowable
    as cost of goods sold. See Rule 142(a). A taxpayer is required to maintain
    20
    (...continued)
    concedes that Alterman and Gibson are entitled to cost-of-goods-sold allowances
    in the amounts allowed in the notice of deficiency for depreciation and sec. 179
    expenses and that the amounts are additional to the allowances for cost of goods
    sold allowed in the notice of deficiency. Because Alterman and Gibson failed to
    brief their entitlement to deductions for business expenses related to Altermeds,
    LLC, including depreciation and sec. 179 expenses, and because they argue that
    the amounts of deductions they reported for depreciation and sec. 179 expenses
    should be recharacterized as cost of goods sold, they have waived any argument
    that they are entitled to the deductions allowed by the notice of deficiency for
    depreciation and sec. 179 expenses.

    [*31] sufficient permanent records to substantiate income, including cost of goods
    sold. See sec. 6001; sec. 1.6001-1(a), (d), Income Tax Regs. However, the Court
    may estimate cost of goods sold under a variation of the Cohan rule even when
    cost of goods sold is not fully substantiated, provided that there is a reasonable
    basis for making such an estimate. Cohan v. Commissioner, 
    39 F.2d 540
    , 543-544
    (2d Cir. 1930); Vanicek v. Commissioner, 
    85 T.C. 731
    , 743 (1985); see Olive v.
    Commissioner, 
    139 T.C. at 34
    .
    Properly computed, cost of goods sold equals
    !      the cost of merchandise on hand at the beginning of the taxable year
    (“beginning inventory”), sec. 1.471-3(a), Income Tax Regs.,
    !      plus the cost of merchandise purchased since the beginning of the
    taxable year (“purchase costs”), 
    id.
     para. (b),
    !      plus the direct and indirect cost of producing merchandise
    (“production costs”), 
    id.
     para. (c), sec. 1.471-11, Income Tax Regs.,
    !      minus the cost of inventory on hand at the end of the tax year
    (“ending inventory”), sec. 1.471-1, Income Tax Regs.
    - 32 -
    [*32] Inventories must be recorded in a legible manner, properly computed and
    summarized, and these inventory records must be preserved by the taxpayer. Sec.
    1.471-2(e), Income Tax Regs.21
    Alterman and Gibson contend that the cost-of-goods-sold allowances for
    2010 and 2011 are:
    2010            2011
    Cost of merchandise purchased during the year        $464,119       $253,089
    Cost of merchandise produced during the year        + 136,094      + 164,431
    Total cost of goods sold                             600,213        417,520
    21
    For businesses for which production, purchase, or sale of merchandise is
    an income-producing factor, inventories at the beginning and end of each taxable
    year are necessary. Sec. 1.471-1, Income Tax Regs. Altermeds, LLC, was such a
    business, and therefore was required to use beginning and ending inventories. At
    one point during discovery, Alterman and Gibson asserted that Rev. Proc. 2000-
    22, 2000-
    1 C.B. 1008
    , as modified and superseded by Rev. Proc. 2001-10, 2001-
    1 C.B. 272
    , relieved Altermeds, LLC, of the obligation to account for inventories.
    In response, the IRS filed a memorandum taking the position that Alterman and
    Gibson misinterpreted Rev. Proc. 2000-22, supra. Alterman and Gibson did not
    rely on Rev. Proc. 2000-22, supra, after that. For example, they did not cite Rev.
    Proc. 2000-22, supra, in their briefs. Therefore, they have waived any argument
    that Rev. Proc. 2000-22, supra, relieved Altermeds, LLC, of the obligation to
    account for inventories.
    The Schedules C for Altermeds, LLC, reported that its income was
    calculated using the cash method of accounting. In certain situations, farmers may
    use the cash method of accounting as an alternative to the inventory method.
    Kennedy v. Commissioner, 
    89 T.C. 98
    , 103 (1987). Alterman and Gibson have
    not contended that they are farmers for this purpose and therefore have waived any
    argument that they were entitled to use the cash method of accounting as farmers.
    - 33 -
    [*33] By comparison the IRS concedes that the cost-of-goods-sold allowances for
    2010 and 2011 are:22
    2010        2011
    Total cost of goods sold       $452,292      $232,772
    The IRS makes a threshold argument that the method of computing cost of
    goods sold urged by Alterman and Gibson is improper because it does not account
    for beginning and ending inventories. That their method ignores beginning and
    ending inventories can be seen from the formula supra p. 31: cost of goods sold
    equals beginning inventory, plus purchase costs, plus production costs, minus
    ending inventory. Alterman and Gibson’s argument for cost-of-goods-sold
    allowances relies entirely on purchase costs and production costs. It assumes that
    cost of goods sold equals purchase costs plus production costs. Thus, their
    method leaves out beginning inventory and ending inventory. Such a method is
    indeed improper. See sec. 1.471-1, Income Tax Regs.
    As an alternative argument, Alterman and Gibson contend that the Court
    should estimate, under Cohan, the relevant beginning and ending inventories for
    each year. This task is impossible on this record. To calculate cost of goods sold
    for 2010, the relevant beginning inventory is the inventory on hand at the
    22
    For the calculation of these amounts, see supra notes 16 and 17.

    [*34] beginning of 2010, which is by definition the ending inventory for 2009.
    Fox Chevrolet, Inc. v. Commissioner, 
    76 T.C. 708
    , 722 (1981) (“Bearing in mind
    that beginning inventory for any given year is equal to the ending inventory for the
    prior year, it is easy to see that an error in any year carries forward to every
    subsequent year.”). To estimate ending inventory for 2009, we would first need to
    estimate the types of products and unit quantities on hand at the end of 2009. This
    is called a physical inventory.23 There is no information in the record regarding
    the physical inventory on hand at the end of 2009. Even if we had a physical
    inventory for the end of 2009, we would need to assign a cost to each unit. Ending
    inventory for 2009 is composed solely of merchandise purchased during 2009
    because Altermeds, LLC, did not produce any marijuana in 2009 and because it
    began its operations in 2009. There is no information in the record regarding the
    cost of merchandise purchased by Altermeds, LLC, in 2009.24 Alterman and
    23
    A physical count requires a determination of how many types of products
    are in inventory. See Stephen F. Gertzman, Federal Tax Accounting, para.
    6.08[2][a] (2d ed. 1993). Although we generally understand that the dispensary
    sold products like buds, joints, and brownies (and therefore probably had these
    products on hand at the end of 2009), we do not know enough to determine
    whether each of these should be considered a product type or whether each of
    these groups should be broken into different product types.
    24
    Alterman and Gibson attached a Schedule C for Altermeds, LLC, to their
    2009 return. They reported $0 as beginning inventory, which is the correct

    [*35] Gibson have pointed to no evidence in the record to give us a reasonable
    basis for estimating the ending inventory for 2009.25 In conclusion, there is no
    way for us to estimate the ending inventory for 2009 and therefore the beginning
    inventory for 2010.
    It is also impossible to estimate the ending inventory for 2010. We would
    first need to estimate the physical inventory at the end of 2010, i.e., unit quantities
    by product type. Then, using a cashflow assumption (such as first-in-first-out), we
    would assign a cost value to each unit of physical inventory at the end of 2010 by
    importing a cost value from (1) a unit in the beginning inventory for 2010, (2) a
    unit purchased during 2010, or (3) a unit produced during 2010. Secs. 1.471-1,
    1.471-3, 1.471-11, Income Tax Regs.; see also Stephen F. Gertzman, Federal Tax
    Accounting, paras. 6.06, 6.07, and 6.08 (2d ed. 1993). As explained above,

    amount because Altermeds, LLC, started operating in 2009. They reported no
    production costs. They reported purchase costs of $72,564 but the record does not
    contain evidence to show how this dollar amount was calculated, such as receipts
    for merchandise purchases, a physical inventory or other documentation. Ending
    inventory for 2009 was reported as $0. We find the ending inventory amount
    unreliable. If Altermeds, LLC’s inventory was $0 at the end of 2009, it would not
    have had any inventory on hand. We find this unlikely. Alterman and Gibson
    calculated cost of goods sold using only purchase costs, ignoring ending
    inventory. This is incorrect.
    25
    They reported on Altermeds, LLC’s 2010 Schedule C the beginning
    inventory as zero, but they do not argue that this amount is correct.
    - 36 -
    [*36] however, we do not have the cost values for units in the beginning inventory
    for 2010.26 And, for units purchased during 2010, at most we have aggregate cost
    data, rather than the cost of any particular unit of merchandise.27 And, for units
    produced during 2010, we cannot even tell from the record whether any units of
    any type of marijuana merchandise were produced by Altermeds, LLC, during
    2010.
    To estimate ending inventory for 2011, there are similar problems that are
    magnified by the lack of data from prior years. Furthermore, by 2011, Altermeds,
    26
    The following hypothetical illustrates the importance of knowing the cost
    of beginning inventory. Suppose the following:
    !      In 2009, Altermeds, LLC, buys three joints at different times during
    the year for $3, $4, and $5, respectively.
    !      In 2009, it sells none of these joints. So all three joints are in the
    ending inventory in 2009 (and therefore are in beginning inventory
    for 2010).
    !      In 2010, Altermeds, LLC, sells two of the three joints.
    If we use the first-in-first-out cashflow assumption, then the two joints sold in
    2010 were the $3 and $4 joints. The $5 joint remains in inventory in 2010 and it
    has an inventory cost of $5. The $5 amount is used to compute ending inventory
    for 2010 (along with the cost of all other products in ending inventory). Thus, we
    can compute ending inventory for 2010 only if we know beginning inventory for
    2010.
    27
    The check-register entries contain the most detail in the record concerning
    merchandise purchases. Nevertheless, we cannot determine unit quantities or
    assign unit costs as the entries are minimally informative and incomplete and
    cover only a fraction of the merchandise purchases.

    [*37] LLC, was growing some of its own marijuana, but the record does not
    include inventory documentation for self-grown marijuana.
    It is improper in this case for the Court to estimate beginning and ending
    inventories. The Court need not reach the question of the cost of purchasing
    merchandise or the cost of producing merchandise during the years at issue. These
    amounts are relevant to cost of goods sold only when they are used in combination
    with beginning and ending inventory.28
    We hold that the cost-of-goods-sold allowances for Altermeds, LLC, are
    $452,292 for 2010 and $232,772 for 2011, which are the amounts conceded by the
    IRS.29
    28
    As a further alternative, Alterman and Gibson contend that the Court
    should determine cost of goods sold for each year by multiplying Altermeds,
    LLC’s gross receipts for each year by a ratio similar to the ratio used in Olive v.
    Commissioner, 
    139 T.C. 19
     (2012), aff’d, 
    792 F.3d 1146
     (9th Cir. 2015). In Olive
    v. Commissioner, 
    139 T.C. at 35
    , we estimated the costs of goods sold for a
    medical-marijuana business by multiplying its gross receipts by a comparative
    ratio of gross receipts to costs of goods sold. We determined the comparative ratio
    of gross receipts to costs of goods sold from the testimony of two expert
    witnesses, Henry Levy and Dale Gieringer. 
    Id.
     Alterman and Gibson called Levy
    as an expert witness. However, the Court ruled that his testimony was
    inadmissible and excluded it from evidence. Unlike the record in Olive, the record
    in this case contains no evidence to support a ratio comparison with other medical-
    marijuana businesses.
    29
    It appears that the IRS determined the amounts it conceded by adding
    production costs to purchase costs. However, it does not concede that this is the

    [*38] III.   Section 6662(a) Penalties
    The IRS takes the position that Alterman and Gibson are liable for 20%
    accuracy-related penalties under section 6662(a) because the underpayments of tax
    for 2010 and 2011 are attributable to negligence or, alternatively, to substantial
    understatements of income tax. See sec. 6662(b)(1) and (2).
    Section 6662(a) imposes a penalty equal to 20% of an underpayment that is
    attributable to negligence, or to a substantial understatement of income tax, or to
    various other causes. Sec. 6662(b). An understatement of income tax is generally
    the difference between the correct tax and the tax reported on the return. Sec.
    6662(d)(2)(A). An understatement is substantial if it exceeds the greater of “(i) 10
    percent of the tax required to be shown on the return for the taxable year, or (ii)
    $5,000.” Sec. 6662(d)(1)(A). Negligence includes any failure by the taxpayer to
    keep adequate books and records or to substantiate items properly. Sec. 1.6662-
    3(b)(1), Income Tax Regs. The penalty is not imposed on any portion of an
    underpayment if there was a reasonable cause for such portion and the taxpayer
    acted in good faith with respect to that portion. Sec. 6664(c)(1). Section
    6751(b)(1) provides that certain penalties cannot be assessed unless the initial
    29
    (...continued)
    proper method of calculating cost of goods sold.
    - 39 -
    [*39] determination of the assessment is personally approved in writing by the
    immediate supervisor of the individual making the determination.
    The IRS has the burden of producing evidence that it is appropriate to
    impose the penalty. Sec. 7491(c); Higbee v. Commissioner, 
    116 T.C. 438
    , 446
    (2001). If the IRS has met its burden of production, the taxpayer has the burden of
    persuading the Court that it is inappropriate to impose the penalty, for example,
    because a portion of the underpayment was due to reasonable cause and good
    faith. Higbee v. Commissioner, 
    116 T.C. at 447
    .
    The IRS’s burden of producing evidence includes producing evidence that
    there was a substantial understatement of income tax. Avrahami v. Commissioner,
    149 T.C. __, __ (slip op. at 98) (Aug. 21, 2017). The taxes reported on the returns
    are determinable because the returns are in the record. Whether substantial
    understatements of income tax exist, and if so, in what amounts, will depend upon
    the recalculation of Alterman and Gibson’s 2010 and 2011 tax liabilities taking
    into account (1) their concession regarding underreported gross receipts and
    (2) the holdings in this opinion. We leave these calculations to the parties under
    Rule 155.
    Regardless of whether the underpayments were due to substantial
    understatements of income tax, we hold that they were due to negligence.
    - 40 -
    [*40] Alterman and Gibson did not keep adequate records to compute reliable
    beginning and ending inventories for Altermeds, LLC. Alterman and Gibson
    acted negligently by failing to keep adequate books and records. See sec. 1.6662-
    3(b)(1), Income Tax Regs. The IRS has met its burden of producing evidence that
    the underpayments are due to negligence. Alterman and Gibson have not
    persuaded us otherwise.
    In a deficiency case, the IRS’s burden of production includes the burden of
    producing evidence that it complied with the supervisory-approval requirement of
    section 6751(b)(1) for certain penalties. See Graev v. Commissioner, 149 T.C. __
    (Dec. 20, 2017), supplementing and overruling in part 
    147 T.C. 460
     (2016). The
    IRS satisfied this burden. It introduced a penalty approval form bearing RA
    Tipton’s name and the signature of RA Tipton’s supervisor demonstrating his
    approval. The supervisor testified that RA Tipton had initially determined the
    penalties and that the supervisor had approved the initial determination.
    At trial, Alterman and Gibson objected to the admissibility of the penalty
    approval form. They argued that the penalty approval form contains RA Tipton’s
    expert opinions and that these opinions could be presented only through expert
    testimony. (RA Tipton testified at trial as a fact witness, not an expert witness.).
    We overruled the objection and admitted the penalty approval form into the
    - 41 -
    [*41] record. In post-trial briefing, Alterman and Gibson urge us to reconsider the
    admissibility of the penalty approval form on the same grounds they gave for their
    objection at trial. Their objection was meritless. The IRS offered the penalty
    approval form to show that RA Tipton had initially determined that the penalties
    should be imposed (and that his supervisor approved the initial determination), not
    to show that the penalties are appropriate.
    Alterman and Gibson argue that the IRS did not comply with the
    supervisory-approval requirement because RA Tipton did not allow petitioners
    enough time to fully present a reasonable-cause defense to the accuracy-related
    penalty before he submitted their case to his supervisor. But section 6751(b)(1)
    requires only that the penalty be “personally approved (in writing) by the
    immediate supervisor”. It does not require the supervisor to follow any specific
    procedure in determining whether to approve the penalty.
    Alterman and Gibson argue that there was reasonable cause for their
    underpayments and that they acted in good faith. Taxpayers can demonstrate
    reasonable cause and good faith if they reasonably relied on advice about the
    appropriate tax treatment of their business. Sec. 1.6664-4(c)(1), Income Tax Regs.
    However, Alterman and Gibson neither sought or received advice from Comiskey
    and Pendleton regarding appropriate inventory accounting or the effect of section
    - 42 -
    [*42] 280E. Sec. 1.6664-4(c)(2), Income Tax Regs. Furthermore, Alterman and
    Gibson did not ask whether businesses that sell medical marijuana or violate
    federal drug trafficking laws are taxed differently from other businesses. This lack
    of inquiry evinces their lack of interest in complying with the federal tax laws.
    Sec. 1.6664-4(b)(1), Income Tax Regs. (providing that the most important factor
    in determining whether a taxpayer acted with reasonable cause and in good faith is
    the extent of the taxpayer’s effort to assess his or her proper tax liability for the
    year).
    Alterman and Gibson did not act with reasonable cause and in good faith
    with respect to the 2010 and 2011 underpayments. Therefore, we hold they are
    liable for the accuracy-related penalty for each year.
    In reaching our holdings, we considered all arguments made, and, to the
    extent not mentioned, we conclude that they are moot, irrelevant, or without merit.
    To reflect the foregoing,
    Decision will be entered under
    Rule 155.
