                               (CONTINUED)
 
Procedure and Administration--Table of Contents
 
Sec.  1.6655-2  Exceptions to imposition of the addition to the tax in 
the case of corporations.

    (a) In general. The addition to the tax under section 6655 will not 
be imposed for any underpayment of any installment of estimated tax if, 
on or before the date prescribed for payment of the installment, the 
total amount of all payments of estimated tax made equals or exceeds the 
amount which would have been required to be paid on or before such date 
if the estimated tax were the least of the following amounts:
    (1) The tax shown on the return for the preceding taxable year, 
provided that the preceding taxable year was a year of 12 months and a 
return showing a liability for tax was filed for such year;
    (2) An amount equal to a tax determined on the basis of the tax 
rates for the taxable year but otherwise on the basis of the facts shown 
on the return for the preceding taxable year and the law applicable to 
such year, in the case of a corporation required to file a return for 
such preceding taxable year; or
    (3) An amount equal to 70 percent of the tax determined by placing 
on an annual basis the taxable income for:
    (i) The first 3 months of the taxable year, in the case of the 
installment required to be paid in the 4th month,
    (ii) Either the first 3 months or the first 5 months of the taxable 
year (whichever results in no addition being imposed), in the case of 
the installment required to be paid in the 6th month,
    (iii) Either the first 6 months or the first 8 months of the taxable 
year (whichever results in no addition being imposed), in the case of 
the installment required to be paid in the 9th month, and
    (iv) Either the first 9 months or the first 11 months of the taxable 
year (whichever results in no addition being imposed), in the case of 
the installment required to be paid in the 12th month.

The taxable income so determined shall be placed on an annual basis by 
first multiplying it by 12, and then dividing the resulting amount by 
the number of months in the taxable year for which the taxable income 
was so determined.
    (4) In the case of a taxpayer whose taxable year consists of 52 or 
53 weeks in accordance with section 441(f), the rules prescribed by 
Sec.  1.441-2(c) shall be applicable in determining, for purposes of 
subparagraph (1) of this paragraph, whether a taxable year was a year of 
12 months and in determining, for purposes of subparagraph (3) of this 
paragraph, the commencement of the 3-month period, or the 3- or 5-month 
period, or the 6- or 8-month period, or the

[[Page 464]]

9- or 11-month period, whichever is applicable. For example, if a 
taxable year begins on December 26, 1956, taxable income for the first 6 
months of such year, for purposes of subparagraph (3) of this paragraph, 
shall be taxable income for the period beginning on December 26, 1956, 
and ending on June 30, 1957, since such taxable year is deemed to 
commence on January 1, 1957, under section 441(f).
    (5) If the end of any accounting period employed by the taxpayer 
(e.g., any of either thirteen 4-week periods or four 13-week periods) 
does not correspond to the termination date of the applicable 3-month, 
or 3- or 5-month, or 6- or 8-month, or 9- or 11-month, period, taxable 
income shall be determined from the beginning of the taxable year to the 
close of the accounting period ending immediately before the termination 
date of the applicable 3-month, or 3- or 5- month, or 6- or 8-month, or 
9- or 11-month, period and to the close of the accounting period within 
which such termination date falls. There shall be determined that 
portion of the difference between the two amounts of taxable income so 
determined which bears the same ratio to the total difference between 
such amounts as the number of days from the close of the first such 
accounting period to the close of such applicable 3-month, or 3- or 5-
month, or 6- or 8-month, or 9- or 11-month, period bears to the total 
number of days between the termination dates of such two accounting 
periods. The portion of the difference between such amounts so 
determined shall then be added to (or subtracted from) taxable income 
determined to the close of the first such accounting period to determine 
taxable income for such applicable 3-month, or 3- or 5-month, or 6- or 
8-month, or 9- or 11-month, period. For example, a taxpayer whose 
taxable year consists of 52 or 53 weeks in accordance with section 
441(f) has a taxable year beginning on December 26, 1956, and thirteen 
4-week accounting periods are employed in determining taxable income. 
Taxable income from December 26, 1956, to the close of the 4-week 
accounting period ending on June 11, 1957, is $200,000, and taxable 
income from December 26, 1956, to the close of the 4-week accounting 
period ending on July 9, 1957, is $228,000. Taxable income for the 6-
month period ending on June 30, 1957, is $219,000 ($200,000+(19x28,000 /
28)).
    (b) Meaning of terms. (1) For the purpose of the exceptions 
described in paragraph (a) of this section, the term tax means the 
excess of the tax imposed by section 11 or 1201(a), or subchapter L, 
chapter 1 of the Code, whichever is applicable, over the sum of $100,000 
plus the credits against tax allowed by sections 32, 33, and 38.
    (2) The credits against the tax allowed by sections 32, 33, and 38, 
are:
    (i) In the case of the exception described in paragraph (a)(1) of 
this section, such credits shown on the return for the preceding taxable 
year,
    (ii) In the case of the exception described in paragraph (a)(2) of 
this section, such credits shown on the return for the preceding taxable 
year, except that if the amount of any such credits would be affected by 
any change in rates, the credits shall be determined by reference to the 
rates applicable to the current taxable year, and
    (iii) In the case of the exception described in paragraph (a)(3) of 
this section, such credits computed under the law and rates applicable 
to the current taxable year.

The provisions of subdivision (ii) of this subparagraph may be 
illustrated by the following example:

    Example. Assume that during the taxable year within which the normal 
tax rate in section 11 changes from 30 percent to 25 percent, 
Corporation X has an underpayment of estimated tax. One-fourth of the 
taxable income of Corporation X for the taxable year preceding that in 
which such underpayment occurs was from sources within foreign country 
Y. The return of Corporation X for such preceding year shows taxable 
income of $325,000 and a tax, without regard to any credits, of 
$163,500. The credit allowed by section 33 on account of taxes paid to 
foreign country Y may not exceed one-fourth of such amount, or $40,875, 
under section 904. The tax for the preceding year, computed by using the 
rates applicable to the year during which the underpayment occurs, would 
be reduced to $147,250 and the limitation under section 904 on the 
credit allowed under section 33 for taxes paid to foreign country Y 
would be reduced to $36,812.50, for purposes of determining the 
applicability of the exception described in paragraph (a)(2) of this 
section.

[[Page 465]]

Therefore, the exception described in paragraph (a)(2) of this section 
will be applicable if, on or before the date prescribed for such 
payment, the total amount paid by Corporation X equals or exceeds the 
amount which would have been required to be paid by such date if the 
estimated tax were $10,437.50 ($147,250 less ($100,000/$36,812.50)).

    (3) For the purpose of the exceptions described in paragraphs (a) 
(1) and (2) of this section, the term ``return for the preceding taxable 
year'' means the income tax return for such year which is required by 
section 6012(a)(2).
    (c) Examples. The application of the exceptions to the imposition of 
the addition to tax may be illustrated by examples employing the 
following statement of facts:

                           Statement of Facts

    Y, a corporation reporting on a calendar year basis, filed a 
declaration on April 15, 1965, showing an estimated tax of $47,100 for 
its taxable year ending December 31, 1965. The first installment of 4 
percent of the estimated tax or $1,884 was paid with the filing of the 
declaration, the second installment in the same amount was paid on June 
15, 1965, and the third and fourth installments of $11,775 (25 percent 
of the estimated tax) each were paid on September 15, 1965, and December 
15, 1965, respectively. Y reported a tax liability of $175,900 on its 
return due March 15, 1966. There was an underpayment in the amount of 
$241.20 on each of the first and second installment dates and $1,507.50 
on each of the third and fourth installments dates determined as 
follows:

(1) Tax as defined in paragraph (b) of this section           $75,900.00
 ($175,900-$100,000)....................................
(2) 70% of item (1).....................................       53,130.00
(3) 4% of item (2)......................................        2,125.20
(4) Deduct amount paid on each of the first and second          1,884.00
 installment dates......................................
                                                         ---------------
(5) Amount of underpayment at each of the first and               241.20
 second installment dates (item (3) minus item (4)).....
                                                         ===============
(6) 25% of item (2).....................................       13,282.50
(7) Deduct amount paid on each of the last two                 11,775.00
 installment dates......................................
                                                         ---------------
(8) Amount of underpayment at each of the third and             1,507.50
 fourth installment dates (item (6) minus item (7)).....
                                                         ===============


The application of each exception described in paragraph (a) of this 
section is determined as follows:
    (1) Assume Y reported a liability of $158,000 on its return for the 
taxable year ending December 31, 1964. If the estimated tax were 
$158,000 reduced by $100,000, or $58,000, the amount which would have 
been required to be paid on or before each of the first and second 
installment dates would be 4 percent of $58,000, or $2,320. The amount 
which would have been required to be paid on or before each of the third 
and fourth installment dates would be 25 percent of $58,000, or $14,500. 
Since these amounts exceed the corresponding amounts actually paid on 
each installment date ($1,884 and $11,775, respectively), the exception 
described in paragraph (a) (1) of this section does not apply.
    (2) As the corporation tax rates under section 11 are different for 
the taxable years ending December 31, 1964, and December 31, 1965, the 
amount of tax determined under paragraph (a)(2) of this section and the 
amounts required to be paid on or before each installment date must be 
determined. The tax liability determined on the basis of the calendar 
year 1965 rates but on the basis of the calendar year 1964 return is 
$151,900 and the estimated tax is $151,900 less $100,000, or $51,900. 
The amount which would have been required to be paid on or before each 
of the first and second installment dates would be 4 percent of $51,900, 
or $2,076, and the amount which would have been required to be paid on 
or before each of the third and fourth installment dates would be 25 
percent of $51,900, or $12,975. Since these amounts exceed the 
corresponding amounts actually paid on each installment date ($1,884 and 
$11,775, respectively), the exception described in paragraph (a)(2) of 
this section does not apply.
    (3) Y determined that its taxable income for the first 3, 5, 6, 8, 
9, and 11 months was $87,500, $155,000, $185,000, $246,000, $288,000, 
and $341,000, respectively. The income for each period is annualized as 
follows:
$87,500x12/3=$350,000
$155,000x12/5=$372,000
$185,000x12/6=$370,000
$246,000x12/8=$369,000
$288,000x12/9=$384,000
$341,000x12/11=$372,000
To determine whether the installment payment made on April 15, 1965, 
equals or exceeds the amount which would have been required to be paid 
if the estimated tax were equal to 70 percent of the tax computed on the 
annualized income for the 3-month period, the following computation is 
necessary:


                                                             3 months

(1) Annualized income...................................        $350,000
(2) Tax on item (1) reduced by $100,000.................          61,500
(3) 70 percent of item (2)..............................          43,050
(4) 4 percent of item (3)...............................           1,722


To determine whether the installment payments made on or before June 15, 
1965, equal or exceed the amount which would have been required to be 
paid if the estimated tax were equal to 70 percent of the tax computed 
on the annualized income for either the 3- or 5-

[[Page 466]]

month period, the following computation is necessary:

------------------------------------------------------------------------
                                            3 months         5 months
------------------------------------------------------------------------
(1) Annualized income.................      $350,000.00      $372,000.00
(2) Tax on item (1) reduced by                61,500.00        72,060.00
 $100,000.............................
(3) 70 percent of item (2)............        43,050.00        50,442.00
(4) 8 percent of item (3).............         3,444.00         4,035.36
------------------------------------------------------------------------

To determine whether the installment payments made on or before 
September 15, 1965, equal or exceed the amount which would have been 
required to be paid if the estimated tax were equal to 70 percent of the 
tax computed on the annualized income for either the 6- or 8-month 
period, the following computation is necessary:

------------------------------------------------------------------------
                                            6 months         8 months
------------------------------------------------------------------------
(1) Annualized income.................      $370,000.00      $369,000.00
(2) Tax on item (1) reduced by                71,100.00        70,620.00
 $100,000.............................
(3) 70 percent of item (2)............        49,770.00        49,434.00
(4) 33 percent of item (3)............        16,424.10        16,313.22
------------------------------------------------------------------------

To determine whether the installment payments made on or before December 
15, 1965, equal or exceed the amount which would have been required to 
be paid if the estimated tax were equal to 70 percent of the tax 
computed on the annualized income for either the 9- or 11-month period, 
the following computation is necessary:

------------------------------------------------------------------------
                                            9 months        11 months
------------------------------------------------------------------------
(1) Annualized income.................      $384,000.00      $372,000.00
(2) Tax on item (1) reduced by                77,820.00        72,060.00
 $100,000.............................
(3) 70 percent of item (2)............        54,474.00        50,442.00
(4) 58 percent of item (3)............        31,594.92        29,256.36
------------------------------------------------------------------------

    The total amounts of all payments of estimated tax actually paid on 
or before the installment dates of April 15, 1965, June 15, 1965, 
September 15, 1965, and December 15, 1965, are $1,884, $3,768, $15,543, 
and $27,318, respectively. Since the total amounts of estimated tax 
actually paid on the first and second installment dates (April 15, 1965, 
and June 15, 1965) exceed the amounts required to be paid on such dates 
if the estimated tax were 70 percent of the tax determined by placing on 
an annualized basis the taxable income for the first 3 months of the 
taxable year, the exception described in paragraph (a)(3) of this 
section applies and no addition to tax will be imposed for the 
installments paid on April 15, 1965, and June 15, 1965. However, since 
the total amount of all payments of estimated tax actually paid on or 
before the third and fourth installment dates (September 15, 1965, and 
December 15, 1965) does not equal or exceed the applicable alternative 
amounts, the addition to the tax with respect to the underpayment of the 
September 15, 1965, and December 15, 1965, installments must be imposed.

    (d) Determination of taxable income for portion of taxable year. In 
determining the applicability of the exception described in paragraph 
(a)(3) of this section, there must be an accurate determination of the 
amount of income and deductions for the appropriate period, that is, for 
the first 3, 5, 6, 8, 9, or 11 months of the taxable year. See paragraph 
(d)(1) of Sec.  1.6654-2 for a description of a similar requirement with 
respect to individuals.
