Sec. 301.6621-2T  Questions and answers relating to the increased rate of 

interest on substantial underpayments attributable to certain tax motivated 
          transactions (temporary).

    The following questions and answers relate to the increased rate of 
interest on substantial underpayments attributable to certain tax 
motivated transactions as provided in section 6621(d) of the Internal 
Revenue Code of 1954, as added by section 144 of the Tax Reform Act of 
1984 (Pub. L. 98-369, 98 Stat. 682):
    Q-1. What is the annual interest rate under section 6621 for 
purposes of computing the amount of interest that must be paid under 
section 6601 (relating to interest on underpayments)?
    A-1. In general, the annual interest rate for purposes of section 
6601 is the adjusted rate of interest established under section 6621 (b) 
Sec. 301.6621-1 (``adjusted rate''). If, however, a tax motivated 
underpayment (as defined in A-2 of this section) for a taxable year is 
substantial (as defined in A-7 of this section), section 6621(d) 
provides that the annual rate of interest with respect to the tax 
motivated underpayment is 120 percent of the adjusted rate (``120

[[Page 398]]

percent rate''), rounded to the nearest tenth of a percent.
    Q-2. What is a tax motivated underpayment?
    A-2. A tax motivated underpayment is the portion of a deficiency (as 
defined in section 6211) of tax imposed by subtitle A (income taxes) 
that is attributable to any of the following tax motivated transactions:
    (1) Any instance in which the value of any property, or the adjusted 
basis of any property, claimed on a return is 150 percent or more of the 
amount determined to be the correct amount of such valuation or adjusted 
basis (i.e., a valuation overstatement within the meaning of section 
6659(c)(1));
    (2) Any loss disallowed for any period by reason of section 465(a) 
or any amount included in gross income by reason of section 465(e);
    (3) Any credit disallowed for any period by reason of section 
46(c)(8) or section 48(d)(6);
    (4) Any loss disallowed for any period with respect to a straddle, 
as defined in section 1092(c), but without regard to sections 1092 (d) 
and (e);
    (5) Any use of an accounting method that may result in a substantial 
distortion of income for any period (see A-3 of this section); and
    (6) Any deduction disallowed with respect to any other tax motivated 
transactions (see A-4 of this section).
    Q-3. What accounting methods may result in a substantial distortion 
of income for any period under A-2(5) of this section?
    A-3. A deduction or credit disallowed, or income included, in any of 
the circumstances listed below shall be treated as attributable to the 
use of an accounting method that may result in a substantial distortion 
of income and shall thus be a tax motivated transaction that results in 
a tax motivated underpayment:
    (1) Any deduction disallowed for any period by reason of section 464 
or section 278(b), relating to certain expenses of farming syndicates;
    (2) In the case of a taxpayer who computes taxable income using the 
cash receipts and disbursements method of accounting, any interest 
deduction disallowed for any period by reason of section 461(g), 
relating to prepaid interest, provided the interest is not paid with 
respect to indebtedness incurred in connection with (i) the purchase, 
refinancing, or improvement of the principal residence of the taxpayer, 
or (ii) the purchase of consumer goods by the taxpayer;
    (3) Any interest deduction disallowed for any period because the 
amount of the claimed deduction was computed using a method resulting in 
an amount of interest for a period that exceeds the true cost of the 
indebtedness for the period computed by applying the effective rate of 
interest on the loan to the unpaid balance of the loan for the period 
(i.e., the economic accrual of interest for the period), provided the 
interest is not accrued with respect to indebtedness incurred in 
connection with (i) the purchase, refinancing, or improvement of the 
principal residence of the taxpayer, or (ii) the purchase of consumer 
goods by the taxpayer (see Rev. Rul. 83-84, 1983-1 C.B. 97, and sections 
163(e), 446(b), and 483);
    (4) Any deduction disallowed for any period under section 709, 
relating to organization or syndication expenditures of a partnership;
    (5) In the case of any expenditure described in section 248(b) that 
was incurred by an S corporation, any deduction disallowed because it 
exceeds the amount allowable under section 248, relating to 
organizational expenditures;
    (6) Any deduction disallowed for any period under section 267(a), 
relating to transactions between related taxpayers;
    (7) Any deduction disallowed for any period, or any income required 
to be included for any period, under section 467, relating to certain 
payments for the use of property or services;
    (8) Any deduction disallowed for any period under section 461(i), 
relating to certain deductions of tax shelters; and
    (9) In the case of a taxpayer who computes taxable income using the 
cash receipts and disbursements method of accounting, any deduction 
disallowed for any period because (i) the expenditure resulting in the 
deduction was a deposit rather than a payment, (ii) the expenditure was 
prepaid for tax

[[Page 399]]

avoidance purposes and not for a business purpose, or (iii) the 
deduction resulted in a material distortion of income (see, e.g., Rev. 
Rul. 79-229, 1979-2 C.B. 210).
    Q-4. Are any transaction other than those specified in A-2 of this 
section and those involving the use of accounting methods under 
circumstances specified in A-3 of this section considered tax motivated 
transactions under A-2(6) of this section?
    A-4. Yes. Deductions disallowed under the following provisions are 
considered to be attributable to tax motivated transactions:
    (1) Any deduction disallowed for any period under section 183, 
relatiing to an activity engaged in by an individual or an S corporation 
that is not engaged in for profit, and
    (2) Any deduction disallowed for any period under section 165(c)(2), 
relating to any transaction not entered into for profit.
    Q-5. How is the amount of a tax motivated underpayment determined?
    A-5. Except as provided in A-6 of this section, the amount of a tax 
motivated underpayment is detemined in the following manner:
    (1) Calculate the amount of the tax liability for the taxable year 
as if all items of income, gain, loss, deduction, or credit, had been 
reported properly on the income tax return of the taxpayer (``total tax 
liability''); and
    (2) Without taking into account any adjustments to items of income, 
gain, loss, deduction, or credit that are attributable to tax motivated 
transactions (as defined in A-2 through A-4 of this section), calculate 
the amount of the tax liability for the taxable year as if all other 
items of income, gain loss, deduction, or credit had been reported 
properly on the income tax return of the taxpayer (``tax liability 
without regard to tax motivated transactions'').
    (3) The difference between the total tax liability and the tax 
liability without regard to tax motivated transactions is the amount of 
the tax motivated underpayment.

    Example. Taxpayer A, a calendar year taxpayer, files his 1984 income 
tax return reporting $70,000 of taxable income and $23,171 of tax 
liability. On January 20, 1986, A enters into a closing agreement with 
the Internal Revenue Service that includes the following adjustments;




Section 162 deduction disallowed (not tax motivated)..........    $7,500
Loss disallowed under section 465 (tax motivated--see A-2(2)       5,000
 of this section).............................................
Section 170 deduction disallowed because of a valuation           10,000
 overstatement (tax motivated--see A-2(1) of this section)....
Loss disallowed with respect to a straddle as defined in           7,000
 section 1092(c) (tax motivated--see A-2(4) of this section)..
Other adjustments (none of which are tax motivated)...........     4,000






1. Reported taxable income....................................    70,000
  (Add all adjustments to items of income, gain, loss,           +33,500
   deduction, or credit (including tax motivated transactions
   subject to section 6621(d)))...............................
                                                               ---------
  Tax=$39,685 (``total tax liability'').......................   103,500
                                                               =========
2. Reported taxable income....................................    70,000
  (Add adjustments to items of income, gain, loss, deduction,    +11,500
   or credit other than those with respect to items that are
   tax motivated).............................................
                                                               ---------
  Tax=$28,691 (``tax liability without regard to tax motivated    81,500
   transactions'')............................................
                                                               =========


    The tax motivated underpayment (i.e., the underpayment attributable 
to tax motivated transactions) is $10,994 ($39,685-$28,691). 
Accordingly, the interest on $10,994 would be computed at the 120 
percent rate.
    The remainder of the underpayment (i.e., the underpayment not 
attributable to tax motivated transactions) is $5,520 ($28,691 (tax 
liability without regard to tax motivated items)-$23,171 (tax paid with 
return)). The interest on $5,520 would be computed at the adjusted rate.

    Q-6: How are the amounts of the tax motivated underpayment and the 
underpayment attributable to fraud or negligence detemined if all or a 
portion of the taxpayer's underpayment is attributable to one or more 
tax motivated transactions and all or a portion is subject to the 
addition to tax imposed by section 6653(a)(2) (in the case of an 
underpayment attributable to negligence or intentional disregard) or 
section 6653(b)(2) (in the case of an underpayment attributable to 
fraud)?
    A-6: If all or a portion of the taxpayer's underpayment is 
attributable to tax motivated transactions, and all or a portion is 
attributable to fraudulent or negligent items (i.e., items that

[[Page 400]]

result in an underpayment subject to the addition to tax imposed by 
section 6653 (a)(2) or (b)(2)), the amount of the tax motivated 
underpayment and the underpayment attributable to fraud or negligence is 
determined in the following manner:
    (1) Determine the following amounts;
    (i) The tax liability for the taxable year of the taxpayer as if all 
items of income, gain, loss, deduction, or credit had been reported 
properly on the income tax return of the taxpayer (``total tax 
liability'');
    (ii) The tax liability for the taxable year of the taxpayer as if 
all items of income, gain, loss, deduction, or credit without taking 
into account adjustments to items of income, gain, loss, deduction, or 
credit that are both (a) attributable to tax motivated transactions and 
(b) subject to section 6653(a)(2) or section 6653(b)(2), had been 
reported properly on the income tax return of the taxpayer (``tax 
liability without regard to fraudulent or negligent tax motivated 
items'');
    (iii) The tax liability for the taxable year of the taxpayer as if 
all items of income, gain, loss, deduction, or credit, without taking 
into account adjustments to items of income, gain, loss, deduction, or 
credit that are subject to section 6653(a)(2) or section 6653(b)(2), had 
been reported properly on the income tax return of the taxpayer (``tax 
liability without regard to fraudulent or negligent items'');
    (iv) The tax liability for the taxable year of the taxpayer as if 
all items of income, gain, loss, deduction, or credit, without taking 
into account adjustments to items of income, gain, loss, deduction, or 
credit that are either subject to section 6653(a)(2) or section 
6653(b)(2) or attributable to tax motivated transactions, had been 
reported properly on the income tax return of the taxpayer (``tax 
liability without regard to tax motivated or fraudulent or negligent 
items'').
    (2) The tax motivated underpayment attributable to fraudulent or 
negligent items is the excess of the total tax liability over the tax 
liability determined without regard to fraudulent or negligent tax 
motivated items ((i)-(ii)).
    (3) The tax motivated underpayment is the sum of (a) the tax 
motivated underpayment attributable to fraudulent or negligent items 
((i)-(ii)) plus (b) the excess of the tax liability without regard to 
fraudulent or negligent items over the tax liability without regard to 
tax motivated or fraudulent or negligent items ((iii)-(iv)). Interest on 
this underpayment is computed at the 120 percent rate.
    (4) The underpayment attributable to fraudulent or negligent items 
is the excess of the total tax liability over the tax liability without 
regard to fraudulent or negligent items ((i)-(iii)). The section 6653 
addition to tax is 50 percent of the interest on this underpayment 
computed at the 120 percent rate on an amount equal to the tax motivated 
underpayment attributable to fraudulent or negligent items (computed in 
(2)) and at the adjusted rate on the remainder.

    Example. Taxpayer A, a calendar year taxpayer, files his 1984 income 
tax return reporting $70,000 of taxable income and $23,171 of tax 
liability. On January 20, 1986, A enters into a closing agreement with 
the Internal Revenue Service that includes the following adjustments:




Section 162 deduction disallowed (not tax motivated but           $7,500
 fraudulent or negligent).....................................
Loss disallowed under section 465(a) (tax motivated--see A-        5,000
 2(2) of this section--and fraudulent or negligent)...........
Section 170 deduction disallowed because of a valuation           10,000
 overstatement (tax motivated--see A-2(1) of this section--but
 not fraudulent or negligent..................................
Loss disallowed with respect to a straddle as defined in           7,000
 section 1092(c) (tax motivated--see A-2(4) of this section
 but not fraudulent or negligent).............................
Other adjustments (none of which are tax motivated or              4,000
 fraudulent or negligent).....................................


    The tax motivated underpayment is determined in the following 
manner:




(1)(i) Reported taxable income................................   $70,000
  (Add all adjustment.........................................   +33,500

   are both tax motivated and fraudulent or negligent.........

(iii) Reported taxable income.................................    70,000

[[Page 401]]


  (All adjustments other than those with respect to items that   +21,000
   are fraudulent or negligent)...............................
                                                               ---------
  Tax=$33,435 (``tax liability without regard fraudulent or       91,000
   negligent items'').........................................
                                                               =========
(iv) Reported taxable income..................................    70,000
  (All adjustments other than those with respect to items that    +4,000
   are either tax motivated or fraudulent or negligent).......
                                                               ---------
  Tax=$25,091 (``tax liability without regard to tax motivated    74,000
   or fraudulent or negligent items'')........................


    (2) The tax motivated underpayment attributable to fraudulent or 
negligent items is $2,500 ((i))-(ii) or $39,685-$37,185).
    (3) The tax motivated underpayment is $10,844 ((2)+((iii)-(iv)) or 
$2,500+($33,435-$25,091)). Interest on $10,844 is computed at the 120 
percent rate.
    (4) The underpayment attributable to fraudulent or negligent items 
is $6,250 ((i)-(iii) or $39,685-$33,435). The section 6653 addition to 
tax is 50 percent of the interest on $6,250, computed at the 120 percent 
rate on an amount equal to the tax motivated underpayment attributable 
to fraudulent or negligent items ($2,500) and at the adjusted rate on 
the remainder ($3,750).
    (5) In summary, therefore, the total underpayment is $16,514 (total 
tax liability ($39,685) less reported tax liability ($23,171)) of which 
$10,844 accrues interest at the 120 percent rate and $5,670 ($16,514-
$10,844) accrues interest at the adjusted rate. In addition, $6,250 of 
the underpayment is subject to the section 6653(a)(2) or section 
6653(b)(2) addition to tax. The underlying interest, upon which the 
addition to tax is based, is computed using the 120 percent rate for the 
portion of the underpayment subject to section 6621(d) ($2,500) and the 
adjusted rate for the portion that is not subject to section 6621(d) 
($3,750).
    Q-7. Does the 120 percent rate apply to all tax motivated 
underpayments?
    A-7. No. The 120 percent rate applies only if the tax motivated 
underpayment for the taxable year is substantial. A tax motivated 
underpayment is substantial only if it exceeds $1,000. If, for example, 
a taxpayer has a $600 underpayment attributable to a valuation 
overstatement (within the meaning of section 6659(c)(1)) and a $500 
underpayment attributable to a loss disallowed under section 465(a), the 
amount of the tax motivated underpayment is $1,100. Because the amount 
of the tax motivated underpayment is thus substantial the 120 percent 
rate applies.
    Q-8. How do carryovers affect the amount of the tax motivated 
underpayment and the amount of the underpayment attributable to 
fraudulent or negligent items?
    A-8. For purposes of A-5 and A-6 of this section, a net operating 
loss carryover, capital loss carryover, or credit carryover is treated 
as a deduction or credit in the year in which taken into account. In any 
computation of tax liability required under A-5 or A-6 of this section 
(i.e., total tax liability, tax liability without regard to tax 
motivated transactions, etc.), the amount of such deduction or credit is 
the amount of the carryover determined as if the taxpayer had properly 
reported in each taxable year all items of income, gain, loss, 
deduction, or credit affecting the amount of the carryover other than 
adjustments of a type not taken into account in such computation of tax 
liability. A net operating loss carryback, capital loss carryback, or 
credit carryback is not taken into account, however, in determining the 
amount of the tax motivated underpayment or the amount of the 
underpayment attributable to fraud or negligence for periods before the 
last date prescribed for filing the income tax return for the taxable 
year in which the carryback arises (determined without regard to 
extensions).
    Q-9. What amount is subject to the 120 percent rate if the amount of 
a taxpayer's unpaid tax for a year is less than the taxpayer's 
substantial tax motivated underpayment?
    A-9. The 120 percent rate applies with respect to the lesser of--
    (1) The amount of unpaid tax for the taxable year determined in 
accordance with Sec. 301.6601-1; or
    (2) The substantial tax motivated underpayment for the taxable year.
    Q-10. What is the effective date for the 120 percent rate?

[[Page 402]]

    A-10. The 120 percent rate applies to interest accruing on a 
deficiency attributable to a substantial tax motivated underpayment 
after December 31, 1984, including interest accruing with respect to 
transactions described in A-3 and A-4 of this section, regardless of the 
date prescribed for payment of the tax.

    Example. Taxpayer A files his income tax return on April 15, 1983 
(the last date prescribed for payment of tax for taxable year 1982 under 
section 6601). In January 1985, Taxpayer A files a petition in the Tax 
Court in response to a statutory notice of deficiency for taxable year 
1982, which includes a tax motivated underpayment of $10,000. In 
September 1986, the Tax Court enters a decision for the Internal Revenue 
Service. Under section 6601, interest accrues at the adjusted rate, 
compounded daily, on tax motivated underpayments outstanding before 
January 1, 1985, and at the 120 percent rate, compounded daily, on 
amounts outstanding after December 31, 1984. The underpayment that is 
subject to the 120 percent rate includes both the $10,000 tax motivated 
underpayment and the interest that accrued on the underpayment at the 
adjusted rate from April 16, 1983, through December 31, 1984.

    Q-11. Can a taxpayer stop the running of interest on a tax motivated 
underpayment by application of a remittance?
    A-11. Yes. The running of interest on a tax liability stops on the 
date the remittance (either a payment of tax or a deposit in the nature 
of a cash bond) is received by the Internal Revenue Service, regardless 
of when the liability is assessed or the remittance is actually applied 
against the taxpayer's account. A taxpayer must make a remittance for 
both the tax liability and the interest that has accrued as of the date 
of remittance to stop the running of interest on both the tax liability 
and the accrued interest with respect to the liability. (See Rev. Proc. 
84-58.) Taxpayer cannot make partial remittances applicable only to tax 
motivated underpayments. Under A-9 of this section, the 120 percent rate 
applies to the amount of unpaid tax to the extent that amount does not 
exceed the tax motivated underpayment. Therefore, a partial remittance 
is applied first to any tax due that is not attributable to a tax 
motivated underpayment. The excess of the partial remittance over tax 
that is not attributable to a tax motivated underpayment, if any, will 
then be applied to tax due that is attributable to a tax motivated 
underpayment.
    Q-12. Does the 120 percent rate apply to interest accruing on 
interest, penalties, additional amounts, or additions to tax as provided 
in section 6601(e)(2)?
    A-12. The 120 percent rate applies only to taxes imposed by subtitle 
A (income taxes) and to interest accrued with respect to such taxes. The 
penalties, additional amounts, and additions to tax specified in section 
6601(e)(2) are not imposed by subtitle A and are not, therefore, 
included in the amount of a tax motivated underpayment. They are, 
however, included in the amount of unpaid tax for purposes of A-9 of 
this section.

    Example. Taxpayer A, for taxable year 1984, has a $10,000 tax 
motivated underpayment and a $2,000 addition to tax for a total unpaid 
tax of $12,000. If A makes a $5,000 payment of tax, he will still have a 
$10,000 tax motivated underpayment but will now have only $7,000 of 
unpaid tax. Pursuant to A-9 of this section, therefore, the 120 percent 
rate would apply to the $7,000 of unpaid tax.
