§661 Deduction for estates and trusts accumulating income or distributing corpus

Title 26 › Subtitle Subtitle A— - Income Taxes › Chapter CHAPTER 1— - NORMAL TAXES AND SURTAXES › Subchapter Subchapter J— - Estates, Trusts, Beneficiaries, and Decedents › Part PART I— - ESTATES, TRUSTS, AND BENEFICIARIES › Subpart Subpart C— - Estates and Trusts Which May Accumulate Income or Which Distribute Corpus › § 661

Summary

Estates and trusts (except trusts covered by subpart B) can deduct from their taxable income the amounts they are required to pay out or properly pay or credit during the year. That includes income that must be paid now and other amounts paid or required to be paid for that year. The deduction is treated as made up of the same mix of income types as the estate’s or trust’s distributable net income, in the same proportions, unless the trust document says otherwise. The IRS has rules for splitting deductions. No part of the deduction is allowed if, after that split, it would be an item not included in the estate’s or trust’s gross income.

Internal Revenue Code — Source: USLM XML via OLRC

(a)In any taxable year there shall be allowed as a deduction in computing the taxable income of an estate or trust (other than a trust to which subpart B applies), the sum of—
(1)any amount of income for such taxable year required to be distributed currently (including any amount required to be distributed which may be paid out of income or corpus to the extent such amount is paid out of income for such taxable year); and
(2)any other amounts properly paid or credited or required to be distributed for such taxable year;
(b)The amount determined under subsection (a) shall be treated as consisting of the same proportion of each class of items entering into the computation of distributable net income of the estate or trust as the total of each class bears to the total distributable net income of the estate or trust in the absence of the allocation of different classes of income under the specific terms of the governing instrument. In the application of the preceding sentence, the items of deduction entering into the computation of distributable net income (including the deduction allowed under section 642(c)) shall be allocated among the items of distributable net income in accordance with regulations prescribed by the Secretary.
(c)No deduction shall be allowed under subsection (a) in respect of any portion of the amount allowed as a deduction under that subsection (without regard to this subsection) which is treated under subsection (b) as consisting of any item of distributable net income which is not included in the gross income of the estate or trust.
