               Additions to the Tax and Additional Amounts


    (a) Addition to the tax--(1) Failure to file tax return. In case of 
failure to file a return required under authority of--
    (i) Subchapter A, chapter 61 of the Code, relating to returns and 
records (other than sections 6015 and 6016, relating to declarations of 
estimated tax, and part III thereof, relating to information returns);
    (ii) Subchapter A, chapter 51 of the Code, relating to distilled 
spirits, wines, and beer;
    (iii) Subchapter A, chapter 52 of the Code, relating to cigars, 
cigarettes, and cigarette papers and tubes; or
    (iv) Subchapter A, chapter 53 of the Code, relating to machine guns, 
destructive devices, and certain other firearms; and

The regulations thereunder, on or before the date prescribed for filing 
(determined with regard to any extension of time for such filing), there 
shall be added to the tax required to be shown on the return the amount 
specified below unless the failure to file the return within the 
prescribed time is shown to the satisfaction of the district director or 
the director of the service center to be due to reasonable cause and not 
to willful neglect. The amount to be added to the tax is 5 percent 
thereof if the failure is for not more than 1 month, with an additional 
5 percent for each additional month or

[[Page 409]]

fraction thereof during which the failure continues, but not to exceed 
25 percent in the aggregate. The amount of any addition under this 
subparagraph shall be reduced by the amount of the addition under 
subparagraph (2) of this paragraph for any month to which an addition to 
tax applies under both subparagraphs (1) and (2) of this paragraph (a).
    (2) Failure to pay tax shown on return. In case of failure to pay 
the amount shown as tax on any return (required to be filed after 
December 31, 1969, without regard to any extension of time for filing 
thereof) specified in subparagraph (1) of this paragraph (a), on or 
before the date prescribed for payment of such tax (determined with 
regard to any extension of time for payment), there shall be added to 
the tax shown on the return the amount specified below unless the 
failure to pay the tax within the prescribed time is shown to the 
satisfaction of the district director, or, as provided in paragraph (a) 
of this section, the Assistant Regional Commissioner (Alcohol, Tobacco 
and Firearms), the director of the service center, to be due to 
reasonable cause and not to willful neglect. Except as provided in 
paragraph (a)(4) of this section, the amount to be added to the tax is 
0.5 percent of the amount of tax shown on the return if the failure is 
for not more than 1 month, with an additional 0.5 percent for each 
additional month or fraction thereof during which the failure continues, 
but not to exceed 25 percent in the aggregate.
    (3) Failure to pay tax not shown on return. In the case of failure 
to pay any amount of any tax required to be shown on a return specified 
in paragraph (a)(1) of this section that is not so shown (including an 
assessment made pursuant to section 6213(b)) within 21 calendar days 
from the date of the notice and demand (10 business days if the amount 
assessed and shown on the notice and demand equals or exceeds $100,000) 
with respect to any notice and demand made after December 31, 1996, 
there will be added to the amount stated in the notice and demand the 
amount specified below unless the failure to pay the tax within the 
prescribed time is shown to the satisfaction of the district director or 
the director of the service center to be due to reasonable cause and not 
to willful neglect. Except as provided in paragraph (a)(4) of this 
section, the amount to be added to the tax is 0.5 percent of the amount 
stated in the notice and demand if the failure is for not more than 1 
month, with an additional 0.5 percent for each additional month or 
fraction thereof during which the failure continues, but not to exceed 
25 percent in the aggregate. For purposes of this paragraph (a)(3), see 
Sec. 301.6601-1(f)(5) for the definition of calendar day and business 
day.
    (4) Reduction of failure to pay penalty during the period an 
installment agreement is in effect--(i) In general. In the case of a 
return filed by an individual on or before the due date for the return 
(including extensions)--
    (A) The amount added to tax for a month or fraction thereof is 
determined by using 0.25 percent instead of 0.5 percent under paragraph 
(a)(2) of this section if at any time during the month an installment 
agreement under section 6159 is in effect for the payment of such tax; 
and
    (B) The amount added to tax for a month or fraction thereof is 
determined by using 0.25 percent instead of 0.5 percent under paragraph 
(a)(3) of this section if at any time during the month an installment 
agreement under section 6159 is in effect for the payment of such tax.
    (ii) Effective date. This paragraph (a)(4) applies for purposes of 
determining additions to tax for months beginning after December 31, 
1999.
    (b) Month defined. (1) If the date prescribed for filing the return 
or paying tax is the last day of a calendar month, each succeeding 
calendar month or fraction thereof during which the failure to file or 
pay tax continues shall constitute a month for purposes of section 6651.
    (2) If the date prescribed for filing the return or paying tax is a 
date other than the last day of a calendar month, the period which 
terminates with the date numerically corresponding thereto in the 
succeeding calendar month and each such successive period shall 
constitute a month for purposes of section 6651. If, in the month of 
February, there is no date corresponding to the

[[Page 410]]

date prescribed for filing the return or paying tax, the period from 
such date in January through the last day of February shall constitute a 
month for purposes of section 6651. Thus, if a return is due on January 
30, the first month shall end on February 28 (or 29 if a leap year), and 
the succeeding months shall end on March 30, April 30, etc.
    (3) If a return is not timely filed or tax is not timely paid, the 
fact that the date prescribed for filing the return or paying tax, or 
the corresponding date in any succeeding calendar month, falls on a 
Saturday, Sunday, or a legal holiday is immaterial in determining the 
number of months for which the addition to the tax under section 6651 
applies.
    (c) Showing of reasonable cause. (1) Except as provided in 
subparagraphs (3) and (4) of this paragraph (b), a taxpayer who wishes 
to avoid the addition to the tax for failure to file a tax return or pay 
tax must make an affirmative showing of all facts alleged as a 
reasonable cause for his failure to file such return or pay such tax on 
time in the form of a written statement containing a declaration that it 
is made under penalties of perjury. Such statement should be filed with 
the district director or the director of the service center with whom 
the return is required to be filed; Provided, That where special tax 
returns of liquor dealers are delivered to an alcohol, tobacco and 
firearms officer working under the supervision of the Regional Director, 
Bureau of Alcohol, Tobacco and Firearms, such statement may be delivered 
with the return. If the district director, the director of the service 
center, or, where applicable, the Regional Director, Bureau of Alcohol, 
Tobacco and Firearms, determines that the delinquency was due to a 
reasonable cause and not to willful neglect, the addition to the tax 
will not be assessed. If the taxpayer exercised ordinary business care 
and prudence and was nevertheless unable to file the return within the 
prescribed time, then the delay is due to a reasonable cause. A failure 
to pay will be considered to be due to reasonable cause to the extent 
that the taxpayer has made a satisfactory showing that he exercised 
ordinary business care and prudence in providing for payment of his tax 
liability and was nevertheless either unable to pay the tax or would 
suffer an undue hardship (as described in Sec. 1.6161-1(b) of this 
chapter) if he paid on the due date. In determining whether the taxpayer 
was unable to pay the tax in spite of the exercise of ordinary business 
care and prudence in providing for payment of his tax liability, 
consideration will be given to all the facts and circumstances of the 
taxpayer's financial situation, including the amount and nature of the 
taxpayer's expenditures in light of the income (or other amounts) he 
could, at the time of such expenditures, reasonably expect to receive 
prior to the date prescribed for the payment of the tax. Thus, for 
example, a taxpayer who incurs lavish or extravagant living expenses in 
an amount such that the remainder of his assets and anticipated income 
will be insufficient to pay his tax, has not exercised ordinary business 
care and prudence in providing for the payment of his tax liability. 
Further, a taxpayer who invests funds in speculative or illiquid assets 
has not exercised ordinary business care and prudence in providing for 
the payment of his tax liability unless, at the time of the investment, 
the remainder of the taxpayer's assets and estimated income will be 
sufficient to pay his tax or it can be reasonably foreseen that the 
speculative or illiquid investment made by the taxpayer can be utilized 
(by sale or as security for a loan) to realize sufficient funds to 
satisfy the tax liability. A taxpayer will be considered to have 
exercised ordinary business care and prudence if he made reasonable 
efforts to conserve sufficient assets in marketable form to satisfy his 
tax liability and nevertheless was unable to pay all or a portion of the 
tax when it became due.
    (2) In determining if the taxpayer exercised ordinary business care 
and prudence in providing for the payment of his tax liability, 
consideration will be given to the nature of the tax which the taxpayer 
has failed to pay. Thus, for example, facts and circumstances which, 
because of the taxpayer's efforts to conserve assets in marketable form, 
may constitute reasonable cause for nonpayment of income taxes may not 
constitute reasonable cause for failure

[[Page 411]]

to pay over taxes described in section 7501 that are collected or 
withheld from any other person.
    (3) If, for a taxable year ending on or after December 31, 1995, an 
individual taxpayer satisfies the requirement of Sec. 1.6081-4(a) of 
this chapter (relating to automatic extension of time for filing an 
individual income tax return), reasonable cause will be presumed, for 
the period of the extension of time to file, with respect to any 
underpayment of tax if--
    (i) The excess of the amount of tax shown on the individual income 
tax return over the amount of tax paid on or before the regular due date 
of the return (by virtue of tax withheld by the employer, estimated tax 
payments, and any payment with an application for extension of time to 
file pursuant to Sec. 1.6081-4 of this chapter) is no greater than 10 
percent of the amount of tax shown on the individual income tax return; 
and
    (ii) Any balance due shown on the individual income tax return is 
remitted with the return.
    (4) If, for a taxable year ending on or after December 31, 1972, a 
corporate taxpayer satisfies the requirements of Sec. 1.6081-3 (a) or 
(b) (relating to an automatic extension of time for filing a corporation 
income tax return), reasonable cause shall be presumed, for the period 
of the extension of time to file, with respect to any underpayment of 
tax if--
    (i) Not less than the amount of tax that would be required as the 
first installment under section 6152(a)(1), if the taxpayer elected to 
pay the tax in installments, is paid on or before the regular due date 
of the return and the second installment is paid on or before 3 months 
after such date,
    (ii) The amount of tax (determined without regard to any prepayment 
thereof) shown on Form 7004, or the amount of tax paid on or before the 
regular due date of the return, is at least 90 percent of the amount of 
tax shown on the taxpayer's Form 1120, and
    (iii) Any balance due shown on the Form 1120 is paid on, or before 
the due date of the return, including any extensions of time for filing.
    (d) Penalty imposed on net amount due--(1) Credits against the tax. 
The amount of tax required to be shown on the return for purposes of 
section 6651(a)(1) and the amount shown as tax on the return for 
purposes of section 6651(a)(2) shall be reduced by the amount of any 
part of the tax which is paid on or before the date prescribed for 
payment of the tax and by the amount of any credit against the tax which 
may be claimed on the return.
    (2) Partial payments. (i) The amount of tax required to be shown on 
the return for purposes of section 6651(a)(2) shall, for the purpose of 
computing the addition for any month, be reduced by the amount of any 
part of the tax which is paid after the date prescribed for payment and 
on or before the first day of such month.
    (ii) The amount of tax stated in the notice and demand for purposes 
of section 6651(a)(3) shall, for the purpose of computing the addition 
for any month, be reduced by the amount of any part of the tax which is 
paid before the first day of such month.
    (e) No addition to tax if fraud penalty assessed. No addition to the 
tax under section 6651 shall be assessed with respect to an underpayment 
of tax if a 50-percent addition to the tax for fraud is assessed with 
respect to the same underpayment under section 6653(b). See section 
6653(d).
    (f) Examples. The provisions of this section may be illustrated by 
the following examples:

    Example 1. (a) Under section 6072(a), income tax returns of 
individuals on a calendar year basis must be filed on or before the 15th 
day of April following the close of the calendar year. Assume an 
individual filed his income tax return for the calendar year 1969 on 
July 20, 1970, and the failure to file on or before the prescribed date 
is not due to reasonable cause. The tax shown on the return is $800 and 
a deficiency of $200 is subsequently assessed, making the tax required 
to be shown on the return, $1,000. Of this amount, $300 has been paid by 
withholding from wages and $400 has been paid as estimated tax. The 
balance due as shown on the return of $100 ($800 shown as tax on the 
return less $700 previously paid) is paid on August 21, 1970. The 
failure to pay on or before the prescribed date is not due to reasonable 
cause. There will be imposed, in addition to interest, an additional 
amount under section 6651(a)(2) of $2.50, which is 2.5 percent (2% for 
the 4 months from April 16 through August 15, and 0.5% for the 
fractional part of the month

[[Page 412]]

from August 16 through August 21) of the net amount due as shown on the 
return of $100 ($800 shown on the return less $700 paid on or before 
April 15). There will also be imposed an additional amount under section 
6651(a)(1) of $58, determined as follows:

20 percent (5% per month for the 3 months from April 16 through      $60
 July 15 and 5% for the fractional part of the month from July
 16 through July 20) of the net amount due of $300 ($1,000
 required to be shown on the return less $700 paid on or before
 April 15).....................................................
Reduced by the amount of the addition imposed under section            2
 6651(a)(2) for those months...................................
                                                                --------
Addition to tax under section 6651(a)(1).......................      $50


    (b) A notice and demand for the $200 deficiency is issued on January 
8, 1971, but the taxpayer does not pay the deficiency until December 23, 
1971. In addition to interest there will be imposed an additional amount 
under section 6651(a)(3) of $10, determined as follows:

Addition computed without regard to limitation:
6 percent (5\1/2\% for the 11 months from January 19, 1971,          $12
 through December 18, 1971, and 0.5% for the fractional part of
 the month from December 19 through December 23) of the amount
 stated in the notice and demand ($200)........................
                                                                --------
Limitation on addition:
25 percent of the amount stated in the notice and demand ($200)      $50
Reduced by the part of the addition under section 6651(a)(1)         $40
 for failure to file attributable to the $200 deficiency (20%
 of $200)......................................................
                                                                --------
Maximum amount of the addition under section 6651(a)(3)........      $10
                                                                ========


    Example 2. An individual files his income tax return for the 
calendar year 1969 on December 2, 1970, and such delinquency is not due 
to reasonable cause. The balance due, as shown on the return, of $500 is 
paid when the return is filed on December 2, 1970. In addition to 
interest and the addition for failure to pay under section 6651(a)(2) of 
$20 (8 months at 0.5% per month, 4%), there will also be imposed an 
additional amount under section 6651(a)(1) of $112.50, determined as 
follows:

Penalty at 5 percent for maximum of 5 months, 25 percent of      $125.00
 $500.........................................................
Less reduction for the amount of the addition under section
 6651(a)(2):
Amount imposed under section 6651(a)(2) for the months in          12.50
 which there is also an addition for failure to file--2\1/2\
 percent for the 5 months April 16 through September 15 of the
 net amount due ($500)........................................
                                                               ---------
Addition to tax under section 6651(a)(1)......................   $112.50
                                                               =========


    (g) Treatment of returns prepared by the Secretary--(1) In general. 
A return prepared by the Secretary under section 6020(b) will be 
disregarded for purposes of determining the amount of the addition to 
tax for failure to file any return pursuant to paragraph (a)(1) of this 
section. However, the return prepared by the Secretary will be treated 
as a return filed by the taxpayer for purposes of determining the amount 
of the addition to tax for failure to pay the tax shown on any return 
and for failure to pay the tax required to be shown on a return that is 
not so shown pursuant to paragraphs (a)(2) and (3) of this section, 
respectively.
    (2) Effective date. This paragraph (g) applies to returns the due 
date for which (determined without regard to extensions) is after July 
30, 1996.
