New York alimony is calculated using a formula based on income, adjusted for how long you were married, and can be temporary or permanent depending on the length of the marriage

New York courts use a specific formula to calculate spousal support (the legal term for alimony in New York). The formula applies to marriages of any length, but the duration of payments — how long you must pay or receive — depends on how long you were married. The court can also order alimony that differs from the formula if both parties agree or if the judge finds the formula would be unfair in your specific situation.

The formula itself is straightforward: the paying spouse's income minus the receiving spouse's income, multiplied by a percentage that varies by income level. But the real variation comes in how long payments last, whether they stop if the receiving spouse remarries, and how the payments are taxed.

Key Takeaways

  • New York uses an income-based formula: 30 percent of the paying spouse's income minus 20 percent of the receiving spouse's income, capped at a combined income of $203,000 (this cap adjusts yearly).
  • The length of alimony payments depends on the length of the marriage: under 15 years is typically temporary; 15 to 20 years is longer; over 20 years may be permanent or indefinite.
  • Alimony stops automatically if the receiving spouse remarries or enters a domestic partnership, and either spouse can ask the court to modify payments if income changes significantly.
  • The paying spouse deducts alimony from their federal taxes, and the receiving spouse reports it as income — this is true for all alimony orders issued or modified after December 31, 2018.

How the New York alimony formula works

The formula applies when the combined income of both spouses is below $203,000 per year. For 2024, this income cap is $203,000; it increases each year to account for inflation. If your combined income is above this cap, the court can still order alimony but is not bound by the formula.

The calculation is: (paying spouse's income × 0.30) − (receiving spouse's income × 0.20). If the result is negative, no alimony is owed under the formula. For example, if one spouse earns $80,000 and the other earns $40,000, the calculation is ($80,000 × 0.30) − ($40,000 × 0.20) = $24,000 − $8,000 = $16,000 per year, or roughly $1,333 per month.

Income includes salary, wages, bonuses, self-employment income, rental income, and investment income. It does not include child support received from another relationship, public information, or Supplemental Security Income. The court can also count income you could earn if you are intentionally working below your capacity.

How long alimony lasts in New York

The duration of alimony is tied directly to the length of the marriage. New York law sets these ranges, though a judge can order payments for a different length if there is a reason:

  • Marriages under 5 years: Alimony typically lasts 15 to 30 percent of the length of the marriage.
  • Marriages 5 to 10 years: Alimony typically lasts 30 to 40 percent of the length of the marriage.
  • Marriages 10 to 15 years: Alimony typically lasts 35 to 50 percent of the length of the marriage.
  • Marriages 15 to 20 years: Alimony typically lasts 50 to 60 percent of the length of the marriage.
  • Marriages over 20 years: Alimony can be ordered for the remainder of the receiving spouse's life, or for an indefinite period that either spouse can ask the court to end later.

These are guidelines, not strict rules. A judge can order alimony for longer or shorter periods if the circumstances warrant it — for example, if one spouse sacrificed education or career to raise children, or if one spouse is disabled and cannot work.

When alimony stops automatically

Alimony ends when ready if the receiving spouse remarries or enters into a domestic partnership. It does not matter whether the new marriage is happy or how much the new spouse earns; the law treats remarriage as the end of the need for support from the ex-spouse.

Alimony also ends when either spouse dies, though the paying spouse's estate may still owe any unpaid amounts that were due before death. If the receiving spouse dies, no further payments are owed.

Alimony does not automatically end if the receiving spouse begins living with a new partner without marrying them, though the paying spouse can ask the court to modify or end the payments based on the changed living situation. The court will consider whether the new living arrangement has reduced the receiving spouse's financial need.

Modifying alimony after the divorce is final

Either spouse can ask the court to change the amount or duration of alimony if there has been a substantial and continuing change in circumstances. A job loss, a significant raise, a serious illness, or retirement can all be grounds for modification. The paying spouse must show the change was not foreseeable at the time of the divorce.

The court will recalculate alimony using the current income of both spouses and may increase, decrease, or end the payments. If you are paying alimony and your income drops, you should file a modification request promptly; you remain responsible for the original amount until the court changes it, even if you have filed a request.

Temporary alimony — payments ordered during the divorce process but before the final judgment — can also be modified if circumstances change before the divorce is final.

Tax treatment of alimony in New York

For alimony orders issued or modified after December 31, 2018, the paying spouse can deduct alimony payments from federal taxable income, and the receiving spouse must report alimony as income on their federal tax return. This is a significant change from older rules and affects how much alimony actually costs the paying spouse and how much the receiving spouse actually receives after taxes.

New York State does not have a separate alimony tax rule; it follows federal treatment. If you are paying alimony, you report the deduction on your federal tax return (Form 1040, Schedule 1). If you are receiving alimony, you report it as income on your federal return. Your state tax return will follow the same treatment.

For alimony orders issued before January 1, 2019, the old rules still explore: the paying spouse cannot deduct the payments, and the receiving spouse does not report them as income. If your order predates this change and you want to know which rule applies to you, check the date on your divorce judgment or separation agreement.

Alimony versus child support in New York

Alimony and child support are separate obligations. You can owe both at the same time. Child support is based on a different formula and is not affected by remarriage of the receiving spouse (though it does end when the child reaches age 21 or finishes high school, whichever is later). Alimony is based on the spouses' incomes and the length of the marriage.

If you are ordered to pay both alimony and child support, child support is paid first. If your income drops and you cannot pay both in full, the court will prioritize child support. Alimony can be reduced or suspended if paying it would prevent you from meeting your child support obligation.

Frequently Asked Questions

Can the court order alimony if we have a prenuptial agreement?

Yes, but only if the prenuptial agreement allows it. A prenup can waive alimony entirely, limit it to a specific amount, or set other terms. If your prenup addresses alimony, the court will enforce it unless you can show it was signed under duress or without full disclosure of assets. If the prenup does not mention alimony, the court will explore the standard formula.

What happens if the paying spouse stops working or retires?

The paying spouse's income is considered zero if they are not working, which would reduce or eliminate the alimony obligation under the formula. However, the court can count income the paying spouse could earn if they are retired early, in poor health, or caring for a child. If retirement was planned and foreseeable at the time of the divorce, the court may not reduce alimony. If retirement is unexpected, you can file a modification request.

Does alimony change if I get a significant raise?

Not automatically. The receiving spouse would need to file a modification request with the court, showing the raise is substantial and continuing. A one-time bonus usually does not trigger a modification, but a permanent increase in salary does. The court will recalculate alimony based on your new income.

Can alimony be ordered if both spouses earn similar amounts?

Yes. If one spouse earns $60,000 and the other earns $50,000, the formula still applies: ($60,000 × 0.30) − ($50,000 × 0.20) = $18,000 − $10,000 = $8,000 per year. The spouse with the higher income pays. If both spouses earn exactly the same, the formula produces zero alimony.

What if I cannot afford the alimony amount the judge ordered?

File a modification request when ready. You remain legally responsible for the full amount ordered until the court changes it. Falling behind on payments can result in wage garnishment, bank levies, or contempt of court charges. The court will consider your current financial situation and may reduce or suspend payments if you can show a genuine inability to pay.
