26 U.S. Code § 215 - Alimony, etc., payments
In the case of an individual, there shall be allowed as a deduction an amount equal to the alimony or separate maintenance payments paid during such individual’s taxable year.
For purposes of this section, the term “alimony or separate maintenance payment” means any alimony or separate maintenance payment (as defined in section 71(b)) which is includible in the gross income of the recipient under section 71.
No deduction shall be allowed under this section with respect to any payment if, by reason of section 682 (relating to income of alimony trusts), the amount thereof is not includible in such individual’s gross income.
1984—Pub. L. 98–369 amended section generally, substituting present provisions for provisions which had declared in: subsec. (a) a general rule as to allowance of deduction for amounts includible under section 71 in the gross income of the wife, payment of which was made within husband’s taxable year, and prohibited any deduction with respect to any payment where by reason of section 71(d) or 682 the amount thereof was not includible in husband’s gross income; and subsec. (b) cross reference to definitions of husband and wife in section 7701(a)(17).
