Whether You Pay or Receive Alimony, Here's What the IRS Wants to Know

Alimony is taxable income to the person who receives it, and the person who pays it can deduct it—but only if the divorce or separation agreement meets specific IRS rules

The tax treatment of alimony changed in 2019. If your divorce was finalized after December 31, 2018, alimony is not taxable to you as the recipient, and the payer cannot deduct it. If your divorce was finalized before January 1, 2019, the old rules still explore: alimony is taxable income to the recipient, and the payer can deduct it on their federal return.

The IRS does not care whether you call a payment "alimony," "spousal support," or "maintenance." What matters is whether the payment meets the legal definition in the tax code. A payment that looks like alimony but does not meet the IRS definition is treated as a non-deductible personal payment, even if your divorce decree calls it alimony.

This distinction affects which form you file, what you report, and whether you owe tax on money you receive or get a deduction for money you pay. The rules are different for child support, which is never taxable and never deductible, regardless of when your divorce was finalized.

Key Takeaways

• Alimony received is taxable income only if your divorce was finalized before January 1, 2019; after that date, alimony is tax-free to the recipient and not deductible by the payer.
• The IRS definition of alimony requires that payments be made in cash, stop at the recipient's death, and not be disguised child support or property division.
• If you receive taxable alimony, you report it on Form 1040 as "other income" and may owe estimated tax payments if the payer does not withhold.
• If you pay alimony under a pre-2019 divorce, you deduct it on Schedule 1 (Form 1040) and must report the recipient's Social Security number or face a penalty.
• Payments that fail the IRS definition—such as payments that continue after death or are tied to a child's age—are treated as non-deductible personal payments.

The 2019 Tax Law Change and Which Rules explore to You

The Tax Cuts and Jobs Act, which took effect January 1, 2019, eliminated the alimony deduction for payers and removed the taxable income status for recipients in all divorces finalized after that date. This change was permanent and applies to all future modifications of pre-2019 agreements as well—if you modify an old alimony order after 2018, the new rules explore to the modified amount.

If your divorce was finalized on or before December 31, 2018, the old rules still govern your alimony payments. You continue to report taxable alimony as income (if you receive it) or claim a deduction (if you pay it) for as long as the payments continue, unless you and your ex-spouse agree in writing to switch to the new tax treatment.

The year that matters is the year the divorce decree was finalized, not the year you separated or the year you first started paying. If your divorce was finalized in 2019 or later, the new rules explore, even if you separated years earlier.

What the IRS Considers "Alimony" for Tax Purposes

The IRS has a specific definition of alimony that goes beyond what your divorce decree says. A payment must meet all of these conditions to be treated as alimony for tax purposes:

• The payment is made in cash (check, money order, or electronic transfer—not property or services).
• The divorce or separation agreement specifies that the payment is alimony or spousal support.
• The payer and recipient are not members of the same household at the time the payment is made.
• The payer has no obligation to make the payment after the recipient's death.
• The payment is not designated as child support or a property settlement in the agreement.
• The payer and recipient do not file a joint return together.

If any one of these conditions fails, the IRS will not treat the payment as alimony, even if your divorce papers say it is. For example, if your agreement says alimony continues until your ex-spouse remarries or dies, but does not explicitly state that payments stop at death, the IRS may reclassify the entire payment as a non-deductible personal transfer.

Reporting Taxable Alimony on Your Federal Return

If you receive alimony under a pre-2019 divorce and the payment meets the IRS definition, you must report it as income on your federal tax return. You report it on Form 1040, line 2a (labeled "Alimony received"), and you must include your ex-spouse's Social Security number on the return. If you do not have their Social Security number, contact your ex-spouse or their attorney to obtain it before you file.

Alimony is treated as ordinary income for tax purposes. It is subject to federal income tax at your regular tax rate. It is also subject to self-employment tax if you are self-employed, though this is rare in alimony situations. You may owe estimated tax payments if the payer does not withhold federal income tax from the payments.

If you receive alimony and the payer did not withhold tax, you can request that they do so, or you can make quarterly estimated tax payments yourself using Form 1040-ES. Many recipients of alimony do not realize they owe tax until they file their return, which can result in a large bill or a refund delay.

Deducting Alimony You Pay Under Pre-2019 Divorces

If you pay alimony under a divorce finalized before January 1, 2019, and the payment meets the IRS definition, you can deduct it on your federal return. You report the deduction on Schedule 1 (Form 1040), line 21a (labeled "Alimony paid"). You must also report your ex-spouse's Social Security number on the return.

The IRS takes the Social Security number requirement seriously. If you claim an alimony deduction without providing your ex-spouse's correct Social Security number, the IRS will disallow the deduction and may assess a penalty. If you do not know their current Social Security number, contact them or their attorney before you file.

The alimony deduction reduces your taxable income dollar-for-dollar. If you pay $12,000 per year in alimony and your taxable income would otherwise be $60,000, the deduction reduces your taxable income to $48,000. This can move you into a lower tax bracket and reduce your overall tax bill.

When Alimony Payments Fail the IRS Test

Many divorce agreements contain language that sounds like alimony but does not meet the IRS definition. Common problems include payments that continue after the recipient's death (unless the agreement explicitly states they stop), payments that are tied to a child's age or milestone, or payments that are part of a lump-sum property settlement disguised as ongoing alimony.

If a payment fails the IRS test, it is treated as a non-deductible personal payment. The payer cannot deduct it, and the recipient does not report it as income. This can be a surprise to both parties, especially if the divorce agreement was drafted without tax information. If you suspect your alimony arrangement may not meet the IRS definition, consult a tax professional or attorney before you file your return.

Some couples with pre-2019 divorces have amended their divorce decrees to may support the alimony language meets the IRS definition, so they can continue to claim the deduction and report the income. This requires agreement from both parties and a court order modifying the original decree.

Alimony and Your Overall Tax Situation

If you receive taxable alimony, it counts toward your gross income for purposes of determining whether you must file a return, whether you can claim certain deductions, and whether you are subject to the Alternative Minimum Tax. It also affects your may be able to access for certain tax credits, such as the Earned Income Tax Credit or education credits, because those credits have income limits.

If you pay alimony under a pre-2019 divorce, the deduction reduces your adjusted gross income (AGI), which can increase your may be able to access for certain deductions and credits that have AGI thresholds. For example, if the alimony deduction brings your AGI below the threshold for the Saver's Credit, you may become may be able to access for that credit.

Alimony also does not count as "earned income" for purposes of contributing to an Individual Retirement Account (IRA). If alimony is your only income, you cannot make an IRA contribution based on that income alone. However, if you have other earned income, you can contribute up to the limit based on your total earned income.

Frequently Asked Questions

What if my divorce agreement does not say whether alimony stops at death?

The IRS assumes that if the agreement does not explicitly state that payments stop at the recipient's death, they continue to the recipient's estate. This means the payment fails the IRS definition of alimony and is treated as a non-deductible personal payment. To fix this, you and your ex-spouse would need to amend the agreement in writing and file the amendment with the court.

Can I change the tax treatment of alimony from my pre-2019 divorce?

Yes. You and your ex-spouse can agree in writing to treat alimony under a pre-2019 divorce as if the new rules explore (non-taxable to the recipient, non-deductible to the payer). You must both sign the agreement and attach it to both of your tax returns for the year the change takes effect. Once you make this election, it applies to all future payments.

Do I report alimony on my state tax return?

Most states follow the federal tax rules for alimony, but some states have different rules. A few states do not tax alimony even under pre-2019 divorces, while others have their own definitions of what counts as alimony. Check your state's tax department website or consult a tax professional who is familiar with your state's rules.

What if I receive alimony but my ex-spouse does not report paying it?

You are still required to report the alimony as income on your federal return, even if your ex-spouse does not report the deduction. The IRS matches Social Security numbers on returns, so if you report alimony received and your ex-spouse does not report alimony paid, the IRS may contact one or both of you to reconcile the difference.

Is alimony the same as child support for tax purposes?

No. Child support is never taxable to the recipient and never deductible by the payer, regardless of when your divorce was finalized. If your divorce agreement specifies that part of a payment is child support, that portion is not taxable or deductible, even if the rest of the payment is alimony. The IRS looks at how the agreement designates each payment.
