Marriage can have a major impact on your income tax situation, even after a separation or divorce. Alimony is cash that one spouse is required to pay to another as a result of a decree of divorce or separate maintenance. You must provide your ex-spouse with your Social Security or tax identification number, as alimony is taxable.
You must to report all alimony received on your federal income tax return. You must file form 1040 -- not 1040A or 1040EZ -- and list it on line 11. Alimony is different from child support, which is not included in taxable income.
Alimony you pay is tax deductible on your federal income tax return. You can claim the alimony deduction on Form 1040, line 31a. You do not need to itemize your deductions to deduct alimony paid. Child support paid is not tax deductible.
