    CHAPTER I--INTERNAL REVENUE SERVICE, DEPARTMENT OF THE TREASURY 
                               (CONTINUED)
 
PART 1_INCOME TAXES--Table of Contents
 
Sec. 1.668(b)-1A  Tax on distribution.

    (a) In general. The partial tax imposed on the beneficiary by 
section 668(a)(2) shall be the lesser of:
    (1) The tax computed under paragraph (b) of this section (the 
``exact'' method), or
    (2) The tax computed under paragraph (c) of this section (the 
``short-cut'' method),

except as provided in Sec. 1.668(b)-4A (relating to failure to furnish 
proper information) and paragraph (d) of this section (relating to 
disallowance of short-cut method). For purposes of this paragraph, the 
method used in the return shall be accepted as the method that produces 
the lesser tax. The beneficiary's choice of the two methods is not 
dependent upon the method that he uses to compute his partial tax 
imposed by section 668(a)(3).
    (b) Computation of partial tax by the exact method. The partial tax 
referred to in paragraph (a)(1) of this section is computed as follows:
    (1) First, compute the tax attributable to the section 666 amounts 
for each of the preceding taxable years. For purposes of this paragraph, 
the ``section 666 amounts'' for a preceding taxable year are the amounts 
deemed distributed under section 666(a) on the last day of the preceding 
taxable year, plus the amount of taxes deemed distributed on such day 
under section 666 (b) or (c). The tax attributable to such amounts in 
each prior taxable year of the beneficiary is the difference between the 
tax for such year computed with the inclusion of the section 666 amounts 
in the beneficiary's gross income and the tax for such year computed 
without including them in such gross income. Tax computations for each 
such year shall reflect a taxpayer's marital, dependency, exemption, and 
filing status for such year. To the extent the undistributed net income 
of a trust deemed distributed in an accumulation distribution includes 
amounts received as an accumulation distribution from another trust, for 
purposes of this paragraph they shall be considered as amounts deemed 
distributed by the trust under section 666(a) on the last day of each of 
the preceding taxable years in which such amounts were accumulated by 
such other trust. For example, assume trust Z, a calendar year trust, 
received in its taxable year 1975 an accumulation distribution from 
trust Y, a calendar year trust, that included undistributed net income 
and taxes of trust Y for the taxable years 1972, 1973, and 1974. To the 
extent an accumulation distribution made by trust Z in its taxable year 
1976 includes such undistributed net income and taxes, it shall be 
considered an accumulation distribution by trust Z in the taxable year 
1976 and under section 666(a) will be deemed distributed on the last day 
of the preceding taxable years 1972, 1973, and 1974.
    (2) From the sum of the taxes for the prior taxable years 
attributable to the section 666 amounts (computed in accordance with 
subparagraph (1) of this paragraph), subtract so much of the amount of 
taxes deemed distributed to the beneficiary under Sec. Sec. 1.666(b)-1A 
and 1.666(c)-1A as does not exceed such sum. The resulting amount, if 
any, is the partial tax, computed under the exact method, for the 
taxable year in which the accumulation distribution is paid, credited, 
or required to be distributed to the beneficiary.
    (3) The provisions of this paragraph may be illustrated by the 
following example:

    Example. (i) Assume that in 1979 a trust makes an accumulation 
distribution of $15,000 to A. The accumulation distribution is allocated 
under section 666(a) in the amounts of $5,000 to 1971, $4,000 to 1972, 
and $6,000 to 1973. Under section 666 (b) and (c), taxes in the amounts 
of $935, $715, and $1,155 (totaling $2,805) are deemed distributed in 
1971, 1972, and 1973, respectively.
    (ii) A, the beneficiary, had taxable income and paid income tax in 
1971-73 as follows:

------------------------------------------------------------------------
               Year                   Taxable income          Tax
------------------------------------------------------------------------
1971..............................     $10,000             $2,190
1972..............................      12,000              2,830
1973..............................      14,000              3,550
------------------------------------------------------------------------

    (iii) Taxes attributable to the section 666 amounts (paragraph (i) 
of this example) are $6,979, computed as follows:

                                  1971

Taxable income including section 666 amounts         $15,935
 ($10,000 + $5,000 + $935)........................
Tax on $15,935...............................................     $4,305
Less: Tax paid by A in 1971..................................      2,190
                                                   ------------

Tax attributable to 1971 section 666 amounts.................      2,115

                                  1972

Taxable income including section 666 amounts         $16,715
 ($12,000 + $4,000 + $715)........................
Tax on $16,715...............................................     $4,620
Less: Tax paid by A in 1972..................................      2,830
                                                   ------------
Tax attributable to 1972 section 666 amounts.................      1,790

                                  1973

Taxable income including section 666 amounts          $21,155
 ($14,000 + $6,000 + $1,155)......................
Tax on $21,155...............................................     $6,624
Less: Tax paid by A in 1973..................................      3,550
                                                   ------------
Tax attributable to 1973 section 666 amounts.................      3,074
Total tax attributable to section 666 amounts:
  1971............................................     $2,115
  1972............................................      1,790
  1973............................................      3,074
                                                   -----------
    Total.........................................      6,979


    (iv) The partial tax computed under the exact method is $4,174, 
computed by subtracting the taxes deemed distributed ($2,805) from the 
tax attributable to the section 666 amounts ($6,979).

    (c) Computation of tax by the short- cut method. (1) The tax 
referred to in paragraph (a)(2) of this section is computed as follows:
    (i) First, determine the number of preceding taxable years of the 
trust on the last day of which an amount is deemed under section 666(a) 
to have been distributed. For purposes of the preceding sentence, the 
preceding taxable years of a trust that has received an accumulation 
distribution from another trust shall include the taxable years of such 
other trust in which an amount was deemed distributed in such 
accumulation distribution. For example, assume trust Z, a calendar year 
trust, received in its taxable year 1975 an accumulation distribution 
from trust Y, a calendar year trust, that included undistributed net 
income of trust Y for the taxable years 1972, 1973, and 1974. To the 
extent an accumulation distribution made by trust Z in its taxable year 
1976 includes such undistributed net income, it shall be considered an 
accumulation distribution by trust Z in the taxable year 1976 and under 
section 666(a) will be deemed distributed on the last day of the 
preceding taxable years 1972, 1973, and 1974. For purposes of this 
subparagraph, such number of preceding taxable years of the trust shall 
not include any preceding taxable year of the trust in which the 
undistributed net income deemed distributed is less than 25 percent of 
(a) the total amounts deemed under section 666(a) to be undistributed 
net income from preceding taxable years divided by (b) the number of 
such preceding taxable years of the trust on the last day of which an 
amount is deemed under section 666(a) to have been distributed without 
application of this sentence. For example, assume that an accumulation 
distribution of $90,000 made to a beneficiary in 1979 is deemed 
distributed in the amounts of $29,000 in each of the years 1972, 1973, 
and 1974, and $3,000 in 1975. The number of preceding taxable years on 
the last day of which an amount was deemed distributed without reference 
to the second sentence of this subparagraph is four. However, the 
distribution deemed made in 1975 ($3,000) is less than $5,625, which is 
25 percent of (a) the total undistributed net income deemed distributed 
under section 666(a) ($90,000) divided by (b) the number of such 
preceding taxable years (4), or $22,500. Therefore, for purposes of this 
subparagraph the accumulation distribution is deemed distributed in only 
3 preceding taxable years (1972, 1973, and 1974).
    (ii) Second, divide the amount (representing the accumulation 
distribution and taxes deemed distributed) required under section 668(a) 
to be included in the income of the beneficiary for the taxable year by 
the number of preceding taxable years of the trust on the last day of 
which an amount is deemed under section 666(a) to have been distributed 
(determined as provided in subdivision (i) of this subparagraph). The 
amount determined under this subdivision, including taxes deemed 
distributed, consists of the same proportion of each class of income as 
the total of each class of income deemed distributed in the accumulation 
distribution bears to the total undistributed net income from such 
preceding taxable years deemed distributed in the accumulation 
distribution. For example, assume that an amount of $50,000 is deemed 
distributed under section 666(a) from undistributed net income of 5 
preceding taxable years of the trust, and consists of $25,000 of 
interest, $15,000 of dividends, and

[[Page 206]]

$10,000 of net rental income. Taxes attributable to such amounts in the 
amount of $10,000 are also deemed distributed. The amount determined 
under this subdivision, $12,000 ($50,000 income plus $10,000 tax divided 
by 5 years), is deemed to consist of $6,000 in interest, $3,600 in 
dividends, and $2,400 in net rental income.
    (iii) Third, compute the tax of the beneficiary for each of the 3 
taxable years immediately preceding the year in which the accumulation 
distribution is paid, credited, or required to be distributed to him,
    (a) With the inclusion in gross income of the beneficiary for each 
of such 3 years of the amount determined under subdivision (ii) of this 
subparagraph, and
    (b) Without such inclusion.

The difference between the amount of tax computed under (a) of this 
subdivision for each year and the amount computed under (b) of this 
subdivision for that year is the additional tax resulting from the 
inclusion in gross income for that year of the amount determined under 
subdivision (ii) of this subparagraph. For example, assume that a 
distribution of $12,000, is includible in the income of each of the 
beneficiary's 3 preceding taxable years when his income (without the 
inclusion of the accumulation distribution) was $20,000, $30,000, and 
$40,000. The inclusion of $12,000 in income would produce taxable income 
of $32,000, $42,000, and $52,000, and the tax attributable to such 
increases would be $4,000, $5,000, and $6,000, respectively.
    (iv) Fourth, add the additional taxes resulting from the application 
of subdivision (iii) of this subparagraph and then divide this amount by 
3. For example, if these additional taxes are $4,000, $5,000, and $6,000 
for the 3 preceding taxable years, this amount would be $5,000 
($4,000+$5,000+ $6,000 divided by 3).
    (v) Fifth, the resulting amount is then multiplied by the number of 
preceding taxable years of the trust on the last day of which an amount 
is deemed under section 666(a) to have been distributed (previously 
determined under subdivision (i) of this subparagraph). For example, if 
an amount is deemed distributed for 5 preceding taxable years, the 
resulting amount would be five times the $5,000 amount.
    (vi) Sixth, the resulting amount, less so much of the amount of 
taxes deemed distributed to the beneficiary under Sec. Sec. 1.666(b)-1A 
and 1.666(c)-1A as does not exceed such resulting amount, is the tax 
under the short-cut method provided in section 668(b)(1)(B).
    (2) The computation of the tax by the short-cut method may be 
illustrated by the following example:

    Example: In 1971, X creates a trust which is to accumulate its 
income and pay the income to Y when Y reaches 30. Y is 19. Over the 11 
years of the trust, the trust earns $1,200 of interest income annually 
and has expenses each year of $100 allocable to the production of 
income. The trust pays a total tax of $1,450 on the accumulated income. 
In 1981, when Y reaches 30, the $9,550 of accumulated undistributed net 
income and the $1,100 of current net income are distributed to Y. Y is 
treated as having received a total distribution of $11,000 (the $9,550 
accumulation distribution plus the taxes paid by the trust which are 
deemed to have been distributed to Y). The income of the current year 
(1981) is taxed directly to Y. The computation is as follows: $11,000 
(accumulation distribution plus taxes) divided by 10 (number of years 
out of which distribution was made) equals $1,100. The $1,100 added to 
the income of the beneficiary's preceding 3 years produces increases in 
tax as follows:

  1980................................................       $350
  1979................................................        300
  1978................................................        250
                                                       -----------------
    Total.............................................        900



$900 (total additional tax) divided by 3 equals $300 (average annual 
increase in tax). $300 (average annual increase in tax) times 10 equals 
$3,000, from which is deducted the amount of taxes ($1,450) paid by the 
trust attributable to the undistributed net income deemed distributed. 
The amount of tax to be paid currently under the short-cut method is 
therefore $1,550.

    (d) Disallowance of short-cut method. If, in any prior taxable year 
of the beneficiary in which any part of the accumulation distribution of 
undistributed net income is deemed to have been distributed under 
section 666(a) to such beneficiary, any part of prior accumulation 
distributions of undistributed net income by each of two or more other 
trusts is deemed under section 666(a) to have been distributed to such 
beneficiary, then the short-cut method under paragraph (c) of this 
section may

[[Page 207]]

not be used and the partial tax imposed by section 668(a)(2) shall be 
computed only under the exact method under paragraph (b) of this 
section. For example, assume that, in 1978, trust X makes an 
accumulation distribution of undistributed net income to A, who is on 
the calendar year basis, and part of the accumulation distribution is 
deemed under section 666(a) to have been distributed on March 31, 1974. 
In 1977, A had received an accumulation distribution of undistributed 
net income from both trust Y and trust Z. Part of the accumulation 
distribution from trust Y was deemed under section 666(a) to have been 
distributed to A on June 30, 1974, and part of the accumulation 
distribution from trust Z was deemed under section 666(a) to have been 
distributed to A on December 31, 1974. Because there were portions of 
accumulation distributions of undistributed net income from two other 
trusts deemed distributed within the same prior taxable year of A 
(1974), the 1978 accumulation distribution from trust X may not be 
computed under the short-cut method provided in paragraph (c) of this 
section. Therefore the exact method under paragraph (b) of this section 
must be used to compute the tax imposed by section 666(a)(2).
