Topic no. 452, Alimony and separate maintenance

Amounts paid to a spouse or a former spouse under a divorce or separation instrument (including a divorce decree, a separate maintenance decree, or a written separation agreement) may be alimony or separate maintenance payments for federal tax purposes.

A payment is alimony or separate maintenance if all the following requirements are met:

Payments not alimony or separate maintenance

Not all payments under a divorce or separation instrument are alimony or separate maintenance. Alimony or separate maintenance doesn't include:

Child support is never deductible and isn't considered income. Additionally, if a divorce or separation instrument provides for alimony and child support, and the payer spouse pays less than the total required, the payments apply to child support first. Only the remaining amount is considered alimony.

Tax treatment of alimony and separate maintenance

Generally, alimony or separate maintenance payments are deductible by the payer spouse and includible in the recipient spouse's income if paid under a divorce or separation agreement executed before 2019.

You can't deduct alimony or separate maintenance payments made under a divorce or separation agreement (1) executed after 2018, or (2) executed before 2019 but later modified if the modification expressly states the repeal of the deduction for alimony payments applies to the modification. Alimony and separate maintenance payments you receive under such an agreement are not included in your gross income.

Reporting taxable alimony or separate maintenance

If you paid amounts that are considered taxable alimony or separate maintenance, you may deduct from income the amount of alimony or separate maintenance you paid whether or not you itemize your deductions. Deduct alimony or separate maintenance payments on Form 1040, U.S. Individual Income Tax Return or Form 1040-SR, U.S. Tax Return for Seniors (attach Schedule 1 (Form 1040), Additional Income and Adjustments to Income PDF ). You must enter the social security number (SSN) or individual taxpayer identification number (ITIN) of the spouse or former spouse receiving the payments or your deduction may be disallowed and you may have to pay a $50 penalty.

If you received amounts that are considered taxable alimony or separate maintenance, you must include the amount of alimony or separate maintenance you received as income. Report alimony received on Form 1040 or Form 1040-SR (attach Schedule 1 (Form 1040) PDF ) or on Form 1040-NR, U.S. Nonresident Alien Income Tax Return (attach Schedule NEC (Form 1040-NR) PDF ). You must provide your SSN or ITIN to the spouse or former spouse making the payments, otherwise you may have to pay a $50 penalty.
