Sec.  1.6654-2  Exceptions to imposition of the addition to the tax 
in the case of individuals.

    (a) In general. The addition to the tax under section 6654 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 
least of the following amounts:
    (1) The amount which would have been required to be paid on or 
before the date prescribed for payment if the estimated tax were 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. However, this subparagraph 
shall not apply with respect

[[Page 453]]

to any taxable year which ends on or after September 30, 1968, for which 
a tax is imposed by section 51 (relating to tax surcharge), in the case 
of a payment of estimated tax the time prescribed for payment of which 
is on or after September 15, 1968.
    (2) The amount which would have been required to be paid on or 
before the date prescribed for payment if the estimated tax were an 
amount equal to a percentage of the tax computed by placing on an annual 
basis the taxable income for the calendar months in the taxable year 
ending before the month in which the installment is required to be paid. 
That percentage is 80 percent in the case of taxable years beginning 
after December 31, 1966, of individuals not referred to in section 
6073(b) (relating to income from farming or fishing), 70 percent in the 
case of taxable years beginning before January 1, 1967, of such 
individuals, and 66\2/3\ percent in the case of individuals referred to 
inferred to in section 6073(b). With respect to taxable years beginning 
after December 31, 1966, the adjusted self-employment income shall be 
taken into account in determining the amount referred to in this 
subparagraph if net earnings from self-employment (as defined in section 
1402(a)) for the taxable year equal or exceed $400. For purposes of this 
subparagraph:
    (i) Taxable income shall be placed on an annualized basis:
    (A) For taxable years beginning after 1976, by:
    (1) Multiplying by 12 (or the number of months in the taxable year 
if less than 12) the adjusted gross income and the itemized deductions 
for the calendar months in the taxable year ending before the month in 
which the installment is required to be paid,
    (2) Dividing the resulting amounts by the number of such calendar 
months,
    (3) Increasing the amount of the annualized adjusted gross income by 
the unused zero bracket amount, if any, determined by reference to the 
annual ized itemized deductions, or decreasing the amount of the 
annualized adjusted gross income by the excess itemized deductions, if 
any, determined by reference to the annualized itemized deductions (the 
amount resulting under this step is annualized tax table income), and
    (4) Deducting from the annualized tax table income the deduction for 
personal exemptions (such personal exemptions being determined as of the 
date prescribed for payment of the installment).

If the taxpaper would be eligible to use the tax tables on the basis of 
annualized tax table income, the amount which would have been required 
to be paid for purposes of this subparagraph may be determined by 
applying the tax tables to annualized tax table income. the amount 
resulting under (3).
    (B) For taxable years beginning before 1977, by:
    (1) Multiplying by 12 (or the number of months in the taxable year 
if less than 12) the taxable income (computed without the standard 
deduction and without the deduction for personal exemptions), or the 
adjusted gross income if the standard deduction is to be used for the 
calendar months in the taxable year ending before the month in which the 
installment is required to be paid,
    (2) Dividing the resulting amount by the number of such calendar 
months, and
    (3) Deducting from such amount the standard deduction, if 
applicable, and the deduction for personal exemptions (such personal 
exemptions being determined as of the date prescribed for payment of the 
installment).
    (ii) The term ``adjusted self-employment income'' means:
    (A) The net earnings from self-employment (as defined in section 
1402(a)) for the calendar months in the taxable year ending before the 
month in which the installment is required to be paid, computed as if 
such months constituted the taxable year, but not more than
    (B) The excess of:
    (1) For taxable years beginning after 1966, $6,600
    (2) For taxable years beginning after 1971, $9,000,
    (3) For taxable years beginning after 1972, $10,800,
    (4) For taxable years beginning after 1973, $13,200, and

[[Page 454]]

    (5) For taxable years beginning after 1974, an amount equal to the 
contribution and benefit base (as determined under section 230 of the 
Social Security Act) which is effective for the calendar year in which 
the taxable year begins, over the amount of the wages (within the 
meaning of section 1402(b)) for such calendar months placed on an annual 
basis. For this purpose, wages are annualized by multiplying by 12 (or 
the number of months in the taxable year in the case of a taxable year 
of less than 12 months) the wages for such calendar months and dividing 
the resulting amount by the number of such months.
    (3) An amount equal to 90 percent of the tax computed, at the rates 
applicable to the taxable year, on the basis of the actual taxable 
income for the calendar months in the taxable year ending before the 
month in which the the installment is required to ber paid, as if such 
months constituted the entire taxable year. For taxable years beginning 
after December 31, 1966, such computation shall include the tax imposed 
by chapter 2 on the actual self-employment income for such months. For 
purposes of this subparagraph, the term ``actual self-employment 
income'' means:
    (i) The net earnings from self-employment (as defined in section 
1402(a))for such calendar months, computed as if such months constituted 
the taxable year, but not more than
    (ii) The excess of:
    (A) For taxable years beginning after 1966, $6,600,
    (B) For taxable years beginning after 1971, $9,000,
    (C) For taxable years beginning after 1972, $10,800,
    (D) For taxable years beginning after 1973, $13,200, and
    (E) For taxable years beginning after 1974, an amount equal to the 
contribution and benefit base (as determined under section 230 of the 
Social Security Act) which is effective for the calendar year in which 
the taxable year begins, over the amount of wages (within the meaning of 
section 1402(b)) for such months.
    (4) The amount which would have been required to be paid on or 
before the date prescribed for payment if the estimated tax were an 
amount equal to a tax determined on the basis of the tax rates and the 
taxpayer's status with respect to personal exemptions under section 151 
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 an individual required to file a return for such 
preceding taxable year.


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, for purposes of subparagraphs (2) and (3) of this paragraph, the 
number of calendar months in a taxable year preceding the date 
prescribed for payment of an installment of estimated tax. For the rules 
to be applied in determining taxable income for any period described in 
subparagraphs (2) and (3) of this paragraph in the case of a taxpayer 
who employs accounting periods (e.g., thirteen 4-week periods or four 
13-week periods) none of which terminates with the end of the applicable 
period described in subparagraph (2) or (3) of this paragraph, see 
paragraph (a)(5) of Sec.  1.6655-2.
    (b) Meaning of terms. As used in this section and Sec.  1.6654-3:
    (1) The term ``tax'' means:
    (i) The tax imposed by chapter 1 of the Code (other than by section 
56), including any qualified State individual income taxes which are 
treated pursuant to section 6361(a) as if they were imposed by chapter 
1, plus
    (ii) For taxable years beginning after December 31, 1966, the tax 
imposed by chapter 2 of the Code, minus
    (iii) The credits against tax allowed by part iv, subchapter A, 
chapter 1 of the Code, other than the credit against tax provided by 
section 31 (relating to tax withheld on wages), and without reduction 
for any payments of estimated tax, minus
    (iv) In the case of an individual who is subject to one or more 
qualified State individual income taxes, the sum of the credits allowed 
against such taxes pursuant to section 6262(b)(2) (B)

[[Page 455]]

or (C) or section 6262(c)(4) and paragraph (c) of Sec.  301.6362-4 of 
this chapter (Regulations on Procedure and Administration) (relating to 
the credit for income taxes of other States or political subdivisions 
thereof) and paragraph (c)(2) of Sec.  301.6361-1 (relating to the 
credit for tax withheld from wages on account of qualified State 
individual income taxes), and minus
    (v) For taxable years ending after February 29, 1980, the 
individual's overpayment of windfall profit tax imposed by section 4986 
of the Code for the taxable year. For this purpose, the amount of such 
overpayment is the sum of (A) the amount by which such individual's 
aggregate windfall profit tax liability for the taxable year as producer 
of crude oil is exceeded by withholding of windfall profit tax for the 
taxable year, and (B) any amount treated under section 6429 or 6430 as 
an overpayment of windfall profit tax for crude oil removed during the 
taxable year. The deemed payment date in section 4995(a)(4)(B) for the 
amount of windfall profit tax withheld with respect to payments for 
crude oil shall have no effect in the determination of the overpayment 
of windfall profit tax.
    (2) The credits against tax allowed by part IV, subchapter A, 
chapter 1 of the Code, are:
    (i) In the case of the exception described in paragraph (a)(1) of 
this section, the credits shown on the return for the preceding taxable 
year,
    (ii) In the case of the exceptions described in paragraph (a)(2) and 
(3) of this section, the credits computed under the law and rates 
applicable to the current taxable year, and
    (iii) In the case of the exception described in paragraph (a)(4) of 
this section, the credits shown on the return for the preceding taxable 
year, except that if the amount of any such credit would be affected by 
any change in rates or status with respect to personal exemptions, the 
credits shall be determined by reference to the rates and status 
applicable to the current taxable year.

A change in rate may be either a change in the rate of tax, such as a 
change in the rate of the tax imposed by section 1 or section 1401, or a 
change in a percentage affecting the computation of the credit, such as 
a change in the rate of withholding under chapter 3 of the Code or a 
change in the percentage of a qualified investment which is specified in 
section 46 for use in determining the amount of the investment credit 
allowed by section 38.
    (3) The term ``return for the preceding taxable year'' means the 
income tax return for such year which is required by section 6012(a)(1) 
and, in the case of taxable years beginning after December 31, 1966, the 
self-employment tax return for such year which is required by section 
607.
    (c) Examples. The following examples illustrate the application of 
the exceptions to the imposition of the addition to the tax for an 
underpayment of estimated tax, in the case of an individual whose 
taxable year is the calendar year:

    Example (1). A, a married man with one child and a dependent parent, 
files a joint return with his spouse, B, for 1955 on April 15, 1956, 
showing taxable income of $44,000 and a tax of $16,760. A and B had 
filed a joint declaration of estimated tax on April 15, 1955, showing an 
estimated tax of $10,000 which was paid in four equal installments of 
$2,500 each on April 15, June 15, and September 15, 1955, and January 
15, 1956. The balance of $6,760 was paid with the return. A and B have 
an underpayment of estimated tax of $433 (\1/4\ of 70 percent of 
$16,760, less $2,500) for each installment date. The 1954 calendar year 
return of A and B showed a liability of $10,000. Since the total amount 
of estimated tax paid by each installment date equalled the amount that 
would have been required to be paid on or before each of such dates if 
the estimated tax were the tax shown on the return for the preceding 
year, the exception described in paragraph (a)(1) of this section 
applies and no addition to the tax will be imposed.
    Example (2). Assume the same facts as in example (1), except that 
the joint return of A and B for 1954 showed taxable income of $32,000 
and a tax liability of $10,400. Assume further that only two personal 
exemptions under section 151 appeared on the 1954 return. The exception 
described in paragraph (a)(1) of this section would not apply. However, 
A and B are entitled to four exemptions under section 151 for 1955. 
Taxable income for 1954 based on four exemptions, but otherwise on the 
basis of the facts shown on the 1954 return, would be $30,800. The tax 
on such amount in the case of a joint return would be $9,836. Since the 
total amount of estimated tax paid by each installment date exceeds the 
amount which would have been required

[[Page 456]]

to be paid on or before each of such dates if the estimated tax were 
$9,836, the exception described in paragraph (a)(4) of this section 
applies and no addition to the tax will be imposed.
    Example (3). C, who is self-employed (other than as a farmer or 
fisherman), has annualized taxable income of $6,900 for the period 
January 1, 1967, through August 31, 1967, the income tax on which is 
$1,171. For the same period his net earnings from self-employment are 
$5,000 and his wages are $2,000. The estimated tax payments made by C 
for 1967 on or before September 15, 1967, total $1,200. For the purposes 
of the exception described in paragraph (a)(2) of this section, the 
adjusted self-employment income is $3,600, computed as follows:

(1) Net earnings from self-employment..........................   $5,000
(2) $6,600 minus annualized wages ($6,600-3,000 ($2,000x12/8)).    3,600
(3) Lesser of (1) or (2).......................................    3,600



The tax on C's adjusted self-employment income would be $230.40 
($3,600x6.4 percent). Since the total amount of estimated tax paid on or 
before September 15, 1967, exceeds $1,121.12, that is, 80 percent of 
$1,401.40 ($1,171+230.40), the exception described in paragraph (a)(2) 
of this section applies and no addition to tax will be imposed.
    Example (4). D, who is self-employed (other than as a farmer or 
fisherman), has actual taxable income of $3,800 for the period January 
1, 1967, through August 31, 1967, the income tax on which is $586. For 
the same period his net earnings from self-employment are $5,000 and his 
wages are $2,000. The estimated tax payments made by D for 1967 on or 
before September 15, 1967, total $840. For the purposes of the exception 
described in paragraph (a)(3) of this section, the actual self-
employment income for this period is $4,600, computed as follows:

(1) Net earnings from self-employment..........................   $5,000
(2) $6,600 minus wages ($6,600-2,000)..........................    4,600
(3) Lesser of (1) or (2).......................................    4,600



The tax on D's actual self-employment income would be $294.40 
($4,600x6.4 percent). Since the total amount of estimated tax paid by 
September 15, 1967, exceeds $792.36, that is, 90 percent of $880.40 
($586+294.40), the exception described in paragraph (a)(3) of this 
section applies and no addition to tax will be imposed.
    Example (5). E and F, his spouse, filed a joint return for the 
calendar year 1967, showing a tax liability of $10,000. The liability, 
attributable primarily to income received during the last quarter of the 
year, included both income and self-employment tax. Their aggregate 
payments of estimated tax on or before September 15, 1967, total $1,350, 
representing three installments of $450 paid on each of the first three 
installment dates prescribed for the taxable year. Since each 
installment paid, $450, was less then $2,000 (\1/4\ of 80 percent of 
$10,000), there was an underpayment on each of the installment dates. 
Assume that the exceptions described in paragraph (a) (1) and (4) of 
this section do not apply. Actual taxable income for the three months 
ending March 31, 1967, was $2,000 and for the five months ending May 31, 
1967, was $4,500. Actual self-employment income, for the same periods, 
was $2,000 and $4,000, respectively. Since the amounts paid by the April 
15 and June 15 installment dates, $450 and $900, respectively, exceed 
$376.20 and $873.90, respectively (90 percent of the income tax on the 
actual taxable income of $2,000 and $4,500, respectively, determined on 
the basis of a joint return, and the self-employment tax on the actual 
self-employment income of $2,000 and $4,000, respectively), the 
exception described in paragraph (a)(3) of this section applies and no 
addition to the tax will be imposed for the underpayments on the April 
15 and June 15 installment dates. For the eight months ending August 31, 
1967, actual taxable income, assuming E and F did not elect to use the 
standard deduction, was $7,500; net earnings from self-employment were 
$6,000 and wages were $2,700. Since the total amount paid by the 
September 15 installment date, $1,350, was less than $1,381.14 (90 
percent of the income tax on the actual taxable income of $7,500 
determined on the basis of a joint return and the self-employment tax on 
actual self-employment income of $3,900 ($6,600-2,700)), the exception 
described in paragraph (a)(3) of this section does not apply to the 
September 15 installment. Furthermore, the exception described in 
paragraph (a)(2) of this section does not apply, as illustrated by the 
following computation:

(1) Income tax:
    Taxable income for the period ending Aug. 31, 1967        $13,050.00
     (without deduction for personal exemptions) on an
     annual basis ($8,700x12/8).............................
  Deduction for two personal exemptions.....................    1,200.00
                                                             -----------
                                                               11,850.00
    Tax on $11,850 (on the basis of a joint return).........    2,227.00
(2) Self-employment tax:
    Net earnings from self-employment.......................    6,000.00
    Adjusted self-employment income ($6,600-4,050 annualized    2,550.00
     wages ($2,700x12/8))...................................
    Tax on adjusted self-employment income ($2,550x6.4            163.20
     percent)...............................................
(3) Total tax ($2,227.00+163.20)............................    2,390.20
(4) \3/4\ of 80 percent of $2,390.20........................    1,434.12
Amount paid by Sept. 15, 1967...............................    1,350.00



An addition to the tax will thus be imposed for the underpayment of 
$1,550 ($2,000-450) on the September 15 installment.
    Example (6). Assume the same facts as in example (5) and assume 
further that adjusted gross income for the eight months ending August 
31, 1967, was $9,200 and the amount of

[[Page 457]]

deductions (other than the deduction for personal exemptions) not 
allowable in determining adjusted gross income aggregate only $500. If E 
and F elect, they may use the standard deduction in computing the tax 
for purposes of the exceptions described in paragraph (a) (2) and (3) of 
this section. Taxable income for purposes of the exception described in 
paragraph (a)(3) of this section would be reduced to $7,080 ($9,200 less 
$1,200 for two personal exemptions and $920 for the standard deduction). 
The income tax thereon is $1,205.20; income tax and self-employment tax 
total $454.80 ($1,205.20+249.60 ($3,900x6.4 percent)). Since the amount 
paid by the September 15 installment date, $1,350, exceeds $1,309.32 (90 
percent of $1,454.80), the exception described in paragraph (a)(3) of 
this section applies. However, the exception described in paragraph 
(a)(2) of this section does not apply, as illustrated by the following 
computation:

Adjusted gross income for period ending Aug. 31, 1967.......   $9,200.00
Adjusted gross income annualized ($9,200x12/8)..............   13,800.00
Taxable income annualized ($13,800 minus $1,200 for two        11,600.00
 personal exemptions and $1,000 for the standard deduction).
Tax on $11,600 (on basis of joint return)...................    2,172.00
Self-employment tax on adjusted self-employment income            163.20
 ($2,550x6.4 percent)
Total tax ($2,172.00+163.20.................................    2,335.20
\3/4\ of 80 percent of $2,335.20............................    1,401.12
Amount paid by Sept. 15, 1967...............................    1,350.00


    Example (7). G was a married individual, 73 years of age, who filed 
a joint return with his wife, H, for the calendar year 1956. H, who was 
70 years of age, had no income during the year. G had taxable income in 
the amount of $7,000 for the eight-month period ending on August 31, 
1956, which included $2,000 of dividend income (after excluding $50 
under section 116) and $900 of rental income. The $7,000 figure also 
reflected a deduction of $2,400 for personal exemptions ($600x4), since 
G and H are both over 65 years of age. The application of the exception 
described in paragraph (a)(2) of this section to an underpayment of 
estimated tax on the September 15 installment date may be illustrated by 
the following computation:

Taxable income for the period ending Aug. 31, 1956 (without   $14,100.00
 deduction for personal exemptions) on an annual basis
 ($9,400x12/8)..............................................
Deduction for personal exemptions...........................    2,400.00
                                                             -----------

Tax (on the basis of a joint return)........................    2,642.00
Dividends received for 8-month period.......................    2,050.00
Less: Amount excluded from gross income under section 116...       50.00
                                                             -----------
Dividends included in gross income..........................    2,000.00
Dividend income annualized ($2,000x12/8)....................    3,000.00

 $3,000)....................................................
                                                             -----------
Tax less dividends received credit..........................    2,522.00
Retirement income (as defined in section 37(c)) includes:
  Dividend income (to extent included in gross income)......    2,000.00
  Rental income.............................................      900.00
                                                             -----------
Total retirement income.....................................    2,900.00
Limit on amount of retirement income under section 37(d)....    1,200.00
Retirement income credit under section 37 (20 percent of          240.00
 $1,200)....................................................
                                                             -----------

Amount determined under the exception described in paragraph    1,198.05
 (a)(2) of this section (\3/4\ of 70 percent of $2,282).....


    Example (8). C, an unmarried individual for whom another taxpayer is 
entitled to a deduction under section 151(e), has adjusted gross income 
of $4,000 for the period January 1, 1977, through August 31, 1977. All 
of C's income is non-exempt interest. For the same period C, who is 
entitled to one personal exemption, has itemized deductions amounting to 
$300. C is entitled to no credits other than the general tax credit. C 
filed a declaration of estimated tax on April 15, 1977, and on or before 
September 15, 1977, makes estimated tax payments for 1977 which total 
$460. For purposes of determing whether the exception described in 
paragraph (a)(2) of this section applies, the following computations are 
necessary:

Adjusted gross income for the period ending Aug. 31,           $6,000.00
 1977, on an annual basis ($4,000 x 12/8)............
Itemized deductions for the period ending Aug. 31,                450.00

    The exception described in paragraph (a)(2) applies, and no addition 
to tax will be imposed.
    Example (9). An unmarried taxpayer entitled to one exemption, has 
adjusted gross income of $16,000 and itemized deductions of $2,000 for 
the period for the period January 1, 1977, through August 31, 1977. D 
has no net earnings from self-employment and is entitled to no credits 
other than the general tax credit. D files a declaration of estimated 
tax on April 15, 1977, and on or before September 15, 1977, makes 
estimated tax payments for 1977 which total $3,000. For purposes of

    The exception described in paragraph (a)(2) does not apply.

    (d) Determination of taxable income for installment periods--(1) In 
general. (i) In determining the applicability of the exceptions 
described in paragraph (a) (2) and (3) of this section, there must be an 
accurate determination of the amount of income and deductions for the 
calendar months in the taxable year preceding the installment date as of 
which the determination is made, that is, for the period terminating 
with the last day of the third, fifth, or eighth month of the taxable 
year. For example, a taxpayer distributes year-end bonuses to his 
employees but does not determine the amount of the bonuses until the 
last month of the taxable year. He may not deduct any portion of such 
year-end bonuses in determining his taxable income for any installment 
period other than the final installment period for the taxable year, 
since deductions are not allowable until paid or accrued, depending on 
the taxpayer's method of accounting.
    (ii) If a taxpayer on an accrual method of accounting wishes to use 
either of the exceptions described in paragraphs (a) (2) and (3) of this 
section, he must establish the amount of income and deductions for each 
applicable period. If his income is derived from a business in which the 
production, purchase, or sale of merchandise is an income-producing 
factor requiring the use of inventories, he will be unable to determine 
accurately the amount of his taxable income for the applicable period 
unless he can establish, with reasonable accuracy, his cost of goods 
sold for the applicable installment period. The cost of goods sold for 
such period shall be considered, unless a more exact determination is 
available, as such part of the cost of goods sold during the entire 
taxable year as the gross receipts from sales for such installment 
period is of gross receipts from sales for the entire taxable year.
    (2) Members of partnerships. The provisions of this subparagraph 
shall apply in determining the applicability of the exceptions described 
in paragraphs (a) (2) and (3) of this section to an underpayment of 
estimated tax by a taxpayer who is a member of a partnership.
    (i) For purposes of determining taxable income, there shall be taken 
into account:
    (A) The partner's distributive share of partnership items set forth 
under section 702,
    (B) The amount of any guaranteed payments under section 707(c), and
    (C) Gains or losses on partnership distributions which are treated 
as gains or losses on sales of property.
    (ii) For purposes of determining net earnings from self-employment 
(for taxable years beginning after December 31, 1966) there shall be 
taken into account:
    (A) The partner's distributive share of income or loss, described in 
section 702(a)(9), subject to the special rules set forth in section 
1402(a) and Sec. Sec.  1.1402(a)-1 to 1.1402(a)-16, inclusive, and
    (B) The amount of any guaranteed paments under section 707(c), 
except for payments received from a partnership not engaged in a trade 
or business within the meaning of section 1402(c) and Sec.  1.1402(c)-1.

In determining a partner's taxable income and, for taxable years 
beginning after December 31, 1966, net earnings from self-employment, 
for the months in his taxable year which precede the month in which the 
installment date falls, the partner shall take into account items set 
forth in sections 702 and 1402(a) for any partnership taxable year 
ending with or within his taxable

[[Page 459]]

year to the extent that such items are attributable year which precede 
the month in which the installment date falls. For special rules used in 
computing a partner's net earnings from self-employment in the case of 
the termination of his taxable year as a result of death, see section 
1402(f) and Sec.  1.1402(f)-1. In addition, a partner shall include in 
his taxing after December 31, 1966, net earnings from self-employment, 
for the months in his taxable year which precede the month in which the 
installment date falls guaranteed payments from the partnership to the 
extent that such guaranteed payments are includible in his taxable 
income for such months. See section 706(a), section 707(c), paragraph 
(c) of Sec.  1.707-1 and section 1402(a).
    (iii) The provisions of subdivision (i) (A) and (B) of this 
subdivision (ii) of this subparagraph may be illustrated by the 
following examples:

    Example (1). A, whose taxable year is the calendar year, is a member 
of a partnership whose taxable year ends on January 31. A must take into 
account, in determining his taxable income for the installment due on 
April 15, 1973, all of his distributive share of partnership items 
described in section 702 and the amount of any guaranteed payments made 
to him which were deductible by the partnership in the partnership 
taxable year beginning on February 1, 1972, and ending on January 31, 
1973. A must take into account, in determining his net earnings from 
self-employment, his distributive share of partnership income or loss 
described in section 702(a)(9), subject to the special rules set forth 
in section 1402(a) and Sec. Sec.  1.1402(a)-1 to 1.1402(a)-16, 
inclusive.
    Example (2). Assume that the taxable year of the partnership of 
which A, a calendar year taxpayer, is a member ends on June 30. A must 
take into account in the determination of his taxable income and net 
earnings from self-employment for the installment due on April 15, 1973, 
his distributive share of partnership items for the period July 1, 1972, 
through March 31, 1973; for the installment due on June 15, 1973, he 
must take into account such amounts for the period July 1, 1972, through 
May 31, 1973; and for the installment due on September 15, 1973, he must 
take into account such amounts for the entire partnership taxable year 
of July 1, 1972, through June 30, 1973 (the date on which the 
partnership taxable year ends).
    (3) Beneficiaries of estates and trusts. In determining the 
applicability of the exceptions described in paragraph (a) (2) and (3) 
of this section as of any installment date, the beneficiary of an estate 
or trust must take into account his distributable share of income from 
the estate or trust for the applicable period (whether or not actually 
distributed) if the trust or estate is required to distribute income to 
him currently. If the estate or trust is not required to distribute 
income currently, only the amounts actually distributed to the 
beneficiary during such period must be taken into account. If the 
taxable year of the beneficiary and the taxable year of the estate or 
trust are different, there shall be taken into account the beneficiary's 
distributable share of income, or the amount actually distributed to him 
as the case may be, during the months in the taxable year of the estate 
or trust ending within the taxable year of the beneficiary which precede 
the month in which the installment date falls. See subparagraph (2) of 
this paragraph for examples of a similar rule which is applied when a 
partner and the partnership of which he is a member have different 
taxable years.
    (e) Special rule in case of change from joint return or separate 
return for the preceding taxable year--(1) Joint return to separate 
returns. In determining the applicability of the exceptions described in 
paragraph (a) (1) and (4) of this section to an underpayment of 
estimated tax, a taxpayer filing a separate return who filed a joint 
return for the preceding taxable year shall be subject to the following 
rule: The tax:
    (i) Shown on the return for the preceding taxable year, or
    (ii) Based on the tax rates and personal exemptions for the current 
taxable year but otherwise determined on the basis of the facts shown on 
the return for the preceding taxable year, and the law applicable to 
such year,

shall be that portion of the tax which bears the same ratio to the whole 
of the tax as the amount of the tax for which the taxpayer would have 
been liable bears to the sum of the taxes for which the taxpayer and his 
spouse would have been liable had each spouse filed a separate return 
for the preceding taxable year. For rules with respect to the allocation 
of joint payments of estimated tax, see section 6015(b) and Sec.  
1.605(b)-1(b).

[[Page 460]]

    (2) Examples. The rule in paragraph (i) of this paragraph may be 
illustrated by the following examples:

    Example (1). H and W filed a joint return for the calendar year 1955 
showing taxable income of $20,000 and a tax of $5,280. Of the $20,000 
taxable income, $18,000 was atributable to H, and $2,000 was 
attributable to W. H and W filed separate returns for 1956. The tax 
shown on the return for the preceding taxable year, for purposes of 
determining the applicability of the exception described in paragraph 
(a)(1) of this section to an underpayment of estimated tax by H for 
1956, is determined as follows:

Taxable income of H for 1955............................         $18,000
Tax on $18,000 (on basis of separate return)............           6,200
Taxable income of W for 1955............................           2,000
Tax on $2,000 (on basis of separate return).............             400
Aggregate tax of H and W (on basis of separate returns).           6,600
Portion of 1955 tax shown on joint return attributable             4,960
 to H (6200/6600x5280)..................................


    Example (2). Assume the same facts as in example (1) and that H and 
W file a joint declaration of estimated tax for 1956 and pay estimated 
tax in amounts determined on the basis of their eligibility for three 
rather than two exemptions for 1956. H and W ultimately file separate 
income tax returns for 1956. Assume further that the exception described 
in paragraph (a)(1) of this section does not apply. The tax based on the 
tax rates and personal exemptions for 1956 but otherwise determined on 
the basis of the facts shown on the return for 1955 and the law 
applicable to 1955, for purposes of determining the applicability of the 
exception described in paragraph (a)(4) of this section to an 
underpayment of estimated tax by H for 1956, is determined as follows:

Taxable income of H and W for 1955 based on additional           $19,400
 personal exemption for 1956................................
Tax on 1955 income based on joint return rate for 1956......       5,076
Portion of 1955 tax attributable to H (computed as in          5900/6300
 example (1) but allowing benefit of additional exemption to
 H).........................................................
Portion of tax attributable to H based on tax rates and           $4,754
 personal exemptions for 1956 but otherwise on facts on 1955
 return ($5900/6300x$5,076).................................



    Example (3). Assume that H and W had the same taxable income in 1972 
as in 1955, and that they filed a joint return for 1972 and separate 
returns for 1973. Assume further that H's taxable income for 1972 
included net earnings from self-employment in excess of the $9,000 
maximum base for the self-employment tax for 1972, and that the joint 
return filed by H and W for 1972 showed tax under Chapter 1 (other than 
section 56) and tax under Chapter 2 totaling $5,055. The tax shown on 
the return for 1972, for purposes of determining the applicability of 
the exception described in paragraph (a)(1) of this section to an 
underpayment of estimated tax by H for 1973, is determined as follows:

Taxable income of H for 1972............................         $18,000
Chapter 1 tax (other than section 56 tax) on $18,000 (on           5,170
 basis of separate return)..............................
Self-employment income of H for 1972....................           9,000
Chapter 2 tax on $9,000.................................            $675
                                                         ---------------
Total of such taxes.....................................          $5,845
Taxable income of W for 1972............................           2,000
Chapter 1 tax (other than section 56 tax) on $2,000 (on              310
 basis of separate return)..............................
                                                         ---------------
Aggregate tax on H and W (on basis of separate returns).          $6,155
Portion of 1972 tax shown on joint return attributable         $4,800.40
 to H (5845/6155x$5,055)................................



    (3) Separate return to joint return. In the case of a taxpayer who 
files a joint return for the taxable year with respect to which there is 
an underpayment of estimated tax and who filed a separate return for the 
preceding taxable year:

    (i) The tax shown on the return for the preceding taxable year, for 
purposes of determining the applicability of the exception described in 
paragraph (a)(1) of this section, shall be the sum of both the tax shown 
on the return of the taxpayer and the tax shown on the return of the 
taxpayer's spouse for such preceding year, and

    (ii) The facts shown on both the taxpayer's return and the return of 
his spouse for the preceding taxable year shall be taken into account 
for purposes of determining the applicability of the exception described 
in paragraph (a)(4) of this section.

    (4) Example. The rules described in subparagraph (3) of this 
paragraph may be illustrated by the following example:

    Example. H and W filed separate income tax returns for the calendar 
year 1954 showing tax liabilities of $2,640 and $350, respectively. In 
1956 they married and participated in the filing of a joint return for 
that year. In the filing of a joint return for that year. Thus, for the 
purpose of determining the applicability of the exceptions described in 
paragraph (a)(1) and (4) of this section to an underpayment of estimated 
tax for the year

[[Page 461]]

1955, the tax shown on the return for the preceding taxable year is 
$2,990 ($2,640 plus $350).
