(a) General rule. Section 331(d)(2)(A) of the Tax Reform Act of 1969 excludes certain accumulated income from the tax imposed by section 668(a)(2) by providing certain exceptions from the definition of an “accumulation distribution.” Any amount paid, credited, or required to be distributed by a trust (other than a foreign trust created by a U.S. person) during a taxable year of the trust beginning after December 31, 1968, and before January 1, 1974, shall not be subject to the tax imposed by section 668(a)(2) to the extent of the portion of such amount that (1) would be allocated under section 666(a) to a preceding taxable year of the trust beginning before January 1, 1969, and (2) would not have been deemed an accumulation distribution because of the provisions of paragraphs (1), (2), (3), or (4) of section 665(b) as in effect on December 31, 1968, had the trust distributed such amounts on the last day of its last taxable year beginning before January 1, 1969. However, the $2,000 de minimis exception formerly in section 665(b) does not apply in the case of any distribution made in a taxable year of a trust beginning after December 31, 1968. Amounts to which this exclusion applies shall reduce the undistributed net income of the trust for the preceding taxable year or years to which such amounts would be allocated under section 666(a). However, since section 668(a)(2) does not apply to such amounts, no amount of taxes imposed on the trust allocable to such undistributed net income is deemed distributed under section 666 (b) and (c).

(b) Application of general rule. The rule expressed in paragraph (a) of this section is applied to the exceptions formerly in section 665(b) as follows:

(1) Distributions from amounts accumulated while beneficiary is under 21. (i) Paragraph (1) of section 665(b) as in effect on December 31, 1968, provided that amounts paid, credited, or required to be distributed to a beneficiary as income accumulated before the birth of such beneficiary or before such beneficiary attains the age of 21 were not to be considered to be accumulation distributions. If an accumulation distribution is made in a taxable year of the trust beginning after December 31, 1968, and before January 1, 1974, and under section 666(a) such accumulation distribution would be allocated to a preceding taxable year beginning before January 1, 1969, no tax shall be imposed under section 668(a)(2) to the extent the income earned by the trust for such preceding taxable year would be deemed under § 1.665(b)-2(b)(1) to have been accumulated before the beneficiary's birth or before his 21st birthday. The provisions of this subparagraph may be illustrated by the following example:

(ii) As indicated in paragraph (a) of this section, a distribution of an amount excepted from the tax otherwise imposed under section 668(a)(2) will reduce undistributed net income for the purpose of determining the effect of a future distribution. Thus, under the facts of the example in subdivision (i) of this subparagraph, the undistributed net income for the trust's taxable year 1968 would be reduced by the amount of the distribution allocated to that year under section 666(a).

(2) Emergency distributions. Paragraph (2) of section 665(b) as in effect on December 31, 1968, provided an exclusion from the definition of an accumulation distribution for amounts properly paid or credited to a beneficiary to meet his emergency needs. Therefore, if an accumulation distribution is made from a trust in a taxable year beginning before January 1, 1974, and under section 666(a) such accumulation distribution would be allocated to a preceding taxable year of the trust beginning before January 1, 1969, no tax shall be imposed under section 668(a)(2) if such distribution would have been considered an emergency distribution under § 1.665(b)-2(b)(2) had it been made in a taxable year of the trust beginning before January 1, 1969. For example, assume a trust on a calendar year basis in 1972 makes an accumulation distribution which under § 1.665(b)-2(b) (2) would be considered an emergency distribution and under section 666(a) the distribution would be allocated to the years 1967, 1968, and 1969. To the extent such amount is allocated to 1967 and 1968, no tax would be imposed under section 668(a)(2).

(3) Certain distributions at specified ages. Paragraph (3) of section 665(b) as in effect on December 31, 1968, provided an exclusion (in the case of certain trusts created before January 1, 1954) from the definition of an accumulation distribution for amounts properly paid or credited to a beneficiary upon his attaining a specified age or ages, subject to certain restrictions (see § 1.665(b)-2(b)(3)). Therefore, a distribution from a trust in a taxable year beginning after December 31, 1968, will not be subject to the tax imposed under section 668(a)(2) to the extent such distribution would be allocated to a preceding taxable year of the trust beginning before January 1, 1969, if such distribution would have qualified under the provisions of § 1.665(b)-2(b)(3) had it been made in a taxable year of the trust to which such section was applicable.

(4) Certain final distributions. Paragraph (4) of section 665(b) as in effect on December 31, 1968, provided an exclusion from the definition of an accumulation distribution for amounts properly paid or credited to a beneficiary as a final distribution of the trust if such final distribution was made more than 9 years after the date of the last transfer to such trust. Therefore, amounts properly paid or credited to a beneficiary as a final distribution of a trust in a taxable year of a trust beginning after December 31, 1968, and before January 1, 1974, will not be subject to the tax imposed under section 668(a)(2) to the extent such distribution would be allocated to a preceding taxable year of the trust beginning before January 1, 1969, if such final distribution was made more than 9 years after the date of the last transfer to such trust. The provisions of this subparagraph may be illustrated by the following example:
