§ 665.
(b)
Accumulation distribution
For purposes of this subpart, except as provided in subsection (c), the term “accumulation distribution” means, for any taxable year of the trust, the amount by which—
(1)
the amounts specified in paragraph (2) of section 661(a) for such taxable year, exceed
(2)
distributable net income for such year reduced (but not below zero) by the amounts specified in paragraph (1) of section 661(a).
For purposes of section 667 (other than subsection (c) thereof, relating to multiple trusts), the amounts specified in paragraph (2) of section 661(a) shall not include amounts properly paid, credited, or required to be distributed to a beneficiary from a trust (other than a foreign trust) as income accumulated before the birth of such beneficiary or before such beneficiary attains the age of 21. If the amounts properly paid, credited, or required to be distributed by the trust for the taxable year do not exceed the income of the trust for such year, there shall be no accumulation distribution for such year.
(e)
Preceding taxable year
For purposes of this subpart—
(1)
In the case of a foreign trust created by a United States person, the term “preceding taxable year” does not include any taxable year of the trust to which this part does not apply.
(2)
In the case of a preceding taxable year with respect to which a trust qualified, without regard to this subpart, under the provisions of subpart B, for purposes of the application of this subpart to such trust for such taxable year, such trust shall, in accordance with regulations prescribed by the Secretary, be treated as a trust to which subpart C applies.
