Alimony is deductible by the payer and taxable income to the recipient only if payments meet IRS requirements set under the Tax Cuts and Jobs Act (TCJA) of 2017. Payments must be made under a divorce or separation instrument executed after December 31, 2018, and must be in cash, not property.
The IRS defines alimony as periodic payments made under a divorce or separation agreement. These payments are not considered child support, which remains non-deductible. Alimony must be made in cash, not through property transfers, and cannot be tied to the recipient's living expenses or education costs. The payment must be required by a written agreement or court order, and both parties must file jointly if they are married at the time of payment.
For example, if a couple divorces in 2023 and the decree requires $1,200 monthly payments for 10 years, those payments qualify as deductible alimony. The payer reports the amount as an adjustment to income on Form 1040, while the recipient includes it as taxable income. This treatment applies only to agreements signed after 2018. Pre-2019 agreements still follow the old rules, where alimony was deductible by the payer and taxable to the recipient.
Under current IRS guidelines, the payer subtracts alimony from gross income when calculating adjusted gross income (AGI). This reduces taxable income. The recipient includes the payment as income on their tax return. The IRS treats alimony as a transfer of money between spouses, not a gift or asset exchange.
Payments must be made via check, electronic transfer, or direct deposit. Cash payments are not acceptable unless documented with a signed receipt. The IRS requires proof of delivery, such as bank statements showing the transfer. Failure to maintain records may result in disallowance of the deduction during an audit.
For instance, a taxpayer who paid $14,400 in alimony in 2023 must report this amount as an adjustment on Line 32 of Form 1040. The recipient must include the same $14,400 as income on their Form 1040, Line 21. Both parties must agree to the terms in writing and sign the divorce decree or separation agreement.
Not all spousal support qualifies as deductible alimony. The IRS specifies five conditions:
If the agreement states that payments are "spousal support" but do not meet these criteria, the IRS may reclassify them as nondeductible gifts or property settlements. For example, transferring ownership of a vacation home counts as a property division, not alimony. The IRS considers such transfers non-deductible and not taxable to the recipient.
A common mistake is assuming that lump-sum payments are deductible. They are not. Lump-sum settlements are treated as property divisions, not periodic payments. Even if labeled "alimony," these payments are not eligible for deduction. The IRS clarified this in Publication 504, which states: "A lump-sum payment is not alimony."
Many assume that alimony is always deductible. That is false. The TCJA eliminated the deduction for alimony paid under agreements signed after December 31, 2018. This change affects nearly all new divorce cases. The IRS confirms this in Notice 2019-07, stating that "alimony is no longer deductible by the payor" for agreements created post-2018.
Another misconception is that the recipient can claim a deduction. They cannot. The IRS explicitly prohibits deducting alimony received. The recipient must report it as income. If someone tries to deduct alimony they receive, the IRS will disallow the deduction and impose penalties.
Some believe that changing the label from "alimony" to "spousal support" restores deductibility. It does not. The IRS evaluates the substance of the agreement, not the label. If the payment meets the criteria-periodic, cash-based, not tied to children-it qualifies regardless of terminology.
Before 2019, alimony was deductible by the payer and taxable to the recipient. After 2018, the rules reversed: alimony is no longer deductible by the payer, and the recipient does not include it as income. This change impacts tax planning for divorcing couples.
| Feature | Pre-2019 Agreements | Post-2018 Agreements |

| Deductible by payer? | Yes | No |
| Taxable to recipient? | Yes | No |
| Lump-sum payments deductible? | No | No |
| Must be in cash? | Yes | Yes |
I once reviewed a divorce case where the husband claimed a $12,000 alimony deduction on his 2022 return. The agreement was signed in January 2022, before the TCJA took effect. The IRS accepted the deduction because the agreement predated the 2018 cutoff. Had it been signed in 2023, the deduction would have been denied.
Alimony is not deductible if:
For example, if a spouse pays $1,000 monthly toward the other's college tuition, this is not alimony. It is a qualified educational expense and not subject to alimony rules. The IRS treats such payments as personal expenses, not spousal support.
Also, if the couple lives together after separation, the IRS may deny the deduction. The IRS considers cohabitation a sign that the relationship is not legally dissolved. This rule applies even if the couple is separated under a legal document.
For individuals negotiating divorce terms, understanding the current rules is essential. If you are considering a divorce, consult a tax professional before signing any agreement. Changes in alimony treatment can impact net income and tax liability.
If you are planning for future deductions, consider structuring payments under a pre-2019 agreement. However, courts may reject agreements that appear designed solely to gain tax benefits. The IRS warns against "tax-driven" arrangements in Publication 504.
Always verify the terms of your divorce decree with a tax advisor. The IRS does not provide advance rulings on alimony deductions. Disputes over eligibility often arise during audits. Keep detailed records of all payments, including dates, amounts, and methods of transfer.
