Alimony and Taxes: What the Tax Cuts and Jobs Act Means for Your Divorce in 2026

How Alimony Is Taxed Under the Tax Cuts and Jobs Act

The Tax Cuts and Jobs Act (TCJA), signed December 22, 2017, rewrote the federal tax treatment of alimony. Section 11051 of the TCJA repealed Internal Revenue Code § 215 — the provision that let the paying spouse deduct alimony payments — and § 71, which had required the receiving spouse to report the payment as taxable income.

The new tax law applies to any divorce or separation agreement executed after December 31, 2018. For those post-2018 orders, alimony is no longer deductible by the payer and no longer taxable to the recipient on a federal return. The Internal Revenue Service treats the payment as a private transfer between former spouses.

The TCJA change is permanent for new divorces — it does not sunset with the rest of the individual tax cuts. So in 2026, any new alimony order signed today follows the post-TCJA rule.

Pre-2019 vs Post-2019 Alimony Tax Rules

The cutoff date matters: a divorce or separation agreement executed on December 31, 2018 still follows the old tax rules forever — even in 2026. An agreement executed one day later follows the new rules. The IRS keys everything off the execution date of the order, not the date the marriage ended.

One exception: a pre-2019 order modified after January 1, 2019 can elect the new rules — but only if both parties agree and the modification expressly says the TCJA treatment applies. Otherwise, modifying an old order does not flip it to the new tax law automatically.

Federal Tax Treatment of Alimony Payments

For any divorce or separation agreement executed after December 31, 2018, alimony payments have no federal tax footprint. The paying spouse cannot deduct the payment, and the receiving spouse does not include it in gross income. The Internal Revenue Service treats the transfer the same way it treats a gift between unrelated people — outside the income tax system.

For pre-2019 agreements, the federal tax treatment is the opposite. The paying spouse claims an above-the-line deduction on Schedule 1 of Form 1040, and the receiving former spouse reports the same amount as taxable income. Both sides must report the recipient’s Social Security number to prove the payment matches.

Is Alimony Taxable Income for the Receiving Spouse?

For post-2018 orders, no. Alimony is not taxable income to the receiving spouse on the federal return. The recipient doesn’t report it, doesn’t pay income tax on it, and doesn’t include it in adjusted gross income.

For pre-2019 orders, yes. The receiving spouse reports the full payment as taxable income on Schedule 1 of Form 1040. The recipient effectively pays income tax at their own marginal rate, which is usually lower than the payer’s — that arbitrage is exactly why Congress repealed the old rule.

Can the Paying Spouse Deduct Alimony from Federal Tax?

Under the current tax law, no. For any divorce or separation agreement executed on or after January 1, 2019, the paying spouse cannot deduct alimony from federal tax. The deduction is gone — the payer covers the alimony with after-tax dollars.

For pre-2019 agreements, the deduction is still available and still above-the-line, meaning the payer doesn’t need to itemize to claim it. It reduces adjusted gross income directly, which can also reduce phase-outs on other credits. That’s the part of the old rule that survives for older orders.

State Tax Treatment of Alimony

State tax doesn’t always follow federal. Some states — including California, New York, New Jersey, Massachusetts, and a handful of others — kept the old rule at the state level. In those states, the paying spouse can still deduct alimony on the state return, and the receiving spouse reports it as taxable income for state purposes.

That creates a split: alimony might be invisible on the federal return but very real on the state return. If you live in a state that still follows the pre-TCJA tax rules, check your state’s tax instructions — or talk to a tax professional — before assuming the federal answer applies.

Alimony vs Child Support: Tax Differences

Child support has always been outside the income tax system. The paying spouse can’t deduct child support, and the receiving spouse doesn’t report it as taxable income — regardless of whether the order was signed in 1995 or 2026. TCJA didn’t change that; it only changed alimony.

That distinction matters when an order bundles spousal support and child support together. The IRS can recharacterize a payment that’s really child support but is labeled alimony — particularly if it drops on a child-related event like a kid turning 18 or graduating. Get the labeling right in the divorce or separation agreement to avoid a later dispute with the Internal Revenue Service.

Separate Maintenance and Tax Rules

Separate maintenance is a court-ordered support payment when spouses live apart but aren’t divorced. For federal tax purposes, the IRS treats separate maintenance the same way it treats alimony — same TCJA rules, same January 1, 2019 cutoff date. The payer can’t deduct it on the federal return, and the recipient doesn’t include it in taxable income, so long as the separate maintenance order was executed after December 31, 2018.

Voluntary support — money one spouse pays the other without a court order — isn’t alimony or separate maintenance for tax purposes. It doesn’t qualify for the old deduction even under pre-2019 rules, and it’s also not taxable to the recipient. The IRS needs a written divorce or separation agreement, court order, or decree to apply the alimony tax rules at all.

What Counts as Alimony for Tax Purposes?

Even for pre-2019 orders, not every payment between former spouses qualifies. To count as alimony for federal income tax, the payment must be in cash (no property transfers), made under a written divorce or separation agreement, paid to or for a spouse or former spouse, and end at the recipient’s death. The spouses must also not file a joint return and not live in the same household when the payment is made.

Property settlements aren’t alimony either. Transfers of property between former spouses under a divorce or separation agreement are governed by IRC § 1041 — a non-recognition rule that means neither side reports gain or loss. The transferring spouse can’t deduct it, and the receiving spouse takes the asset at the original cost basis. Don’t mistake a lump-sum property buyout for deductible alimony, even on a pre-2019 order.
