Alimony & taxes after the TCJA — 2026 guide for payors and payees
The 2017 Tax Cuts and Jobs Act fundamentally changed how alimony is taxed. For divorces finalized after December 31, 2018, the old "deductible for payor / taxable for payee" rule is gone. Here's the full picture for 2026 — including what happens if your divorce predates the TCJA.
The old rule (pre-2019 divorces)
Under the rules that applied before the TCJA:
- The payor could deduct alimony payments from gross income — an "above-the-line" deduction available even without itemizing.
- The payee had to include alimony received in gross income and pay ordinary income tax on it.
This treatment still applies to divorces or separation agreements that were:
- Executed (signed and entered) before January 1, 2019, and
- Have not been modified after December 31, 2018, with the modification explicitly adopting the new rules.
The new rule (post-2018 divorces)
For divorce or separation agreements executed after December 31, 2018:
Payor (paying spouse)
❌ No deduction. Alimony payments are made from after-tax dollars. You cannot deduct them on your federal return.
Payee (receiving spouse)
✅ Not taxable income. Alimony received is not included in gross income and is not subject to federal income tax.
This is a significant shift. Under the old rule, the tax benefit flowed to the higher-earner (payor) via the deduction, which often made alimony more negotiable. Under the new rule, there is no tax benefit to either party — the payor pays from after-tax dollars and the payee receives a tax-free payment.
How the TCJA affects negotiated settlements
The loss of the payor's deduction effectively increases the after-tax cost of alimony for the payor. This has several practical consequences for divorce negotiations:
- Lower settlement amounts: Since the payor can no longer offset the cost with a deduction, payors may push harder for lower alimony amounts. Payees may need to adjust expectations accordingly.
- Gross-up negotiations: Some attorneys negotiate a "gross-up" — a slightly higher alimony amount to approximate what the payee would have netted under the old rules.
- Lump-sum vs. periodic: A lump-sum property settlement is neither deductible nor taxable for either party, making it relatively more attractive to payors compared to periodic alimony under the new rules.
- Retirement account splits (QDROs): These remain non-taxable to the payee at the time of the transfer, making them a popular negotiating tool for replacing some periodic alimony.
What about state income taxes?
Most states conform their tax code to federal tax law — so the TCJA changes generally apply at the state level too. However, a handful of states did not conform to the TCJA alimony changes and still allow payors to deduct alimony (or require payees to report it) under state law:
- California — does not conform to TCJA; alimony is still deductible for the payor and taxable for the payee under California income tax law.
- Massachusetts — generally conforms to pre-TCJA federal law for most provisions.
Always check with a tax professional in your state — this is an area where federal and state treatment can diverge significantly.

Use the calculator
Our alimony calculator estimates monthly gross payment amounts. Remember that post-2018 alimony is paid from after-tax dollars — so the real cost to the payor is higher than it appears in the estimate. A divorce attorney and CPA can model the full after-tax impact for your specific situation.
