Alimony by State: How Spousal Support Works Across the U.S.
Last reviewed: March 2026
Alimony — also called spousal support or spousal maintenance — varies dramatically from state to state. Some states use statutory formulas that produce relatively predictable outcomes. Others leave the amount and duration almost entirely to the judge's discretion. A few have abolished permanent alimony altogether, while others still allow it for long marriages. Try our free alimony calculator to see an estimate based on your state's approach.
This guide provides an overview of how each of the 50 states approaches alimony. Use it as a starting point to understand what you might expect in your state — but keep in mind that your specific outcome depends on many factors, including the length of your marriage, each spouse's income, and the judge assigned to your case. No guide can predict your result with certainty.

Which States Have Alimony Formulas?
A minority of states use income-based formulas to calculate alimony amounts or duration. Illinois uses a straightforward formula: 33.33% of the higher earner's net income minus 25% of the lower earner's net income, capped at 40% of the combined income. New York applies a similar formula using the difference between 2/3 of the higher earner's income and 25% of the lower earner's income. Colorado applies advisory guidelines when combined income falls below $240,000, recommending 40% of the higher earner's monthly adjusted gross income minus 50% of the lower earner's.
The majority of states — including Pennsylvania, Ohio, Georgia, and Virginia — leave both the amount and duration of alimony entirely to judicial discretion. In these states, judges weigh statutory factors like income disparity, marriage length, age, health, and each spouse's contributions. This means outcomes can vary significantly depending on the judge and the facts presented. Even in formula states, courts retain the ability to deviate when circumstances warrant it, so formulas represent a starting point rather than a guarantee.
How Long Does Alimony Last by State?
Alimony duration depends heavily on state law and marriage length. States with duration formulas tie the length of support to the length of the marriage. For example, Massachusetts caps alimony at 50% of the marriage length for marriages of 5–10 years and 60% for 10–15 years. Texas caps duration at 5 years for marriages of 10–20 years and 10 years for marriages over 30 years. Kansas limits alimony to one-third of the marriage length, with a hard cap of 121 months.
In judicial discretion states, duration is far less predictable. Judges consider factors like the recipient's ability to become self-supporting, the standard of living during marriage, and each spouse's age and health. States like New Jersey and Connecticut still allow indefinite alimony for long marriages, while Indiana limits rehabilitative alimony to just 3 years. Utah caps alimony duration at the length of the marriage. For state-specific duration details, see our alimony duration guides for each state.
States That Have Eliminated Permanent Alimony
The trend in American family law is moving away from permanent alimony. Florida made the biggest headlines in 2023 when Governor DeSantis signed SB 1416, eliminating permanent alimony entirely and replacing it with durational support capped at a percentage of the marriage length. Massachusetts enacted the Alimony Reform Act of 2011, which created duration brackets and ended the presumption of permanent alimony that had previously applied in practice for long marriages.
Texas has never allowed traditional permanent alimony — court-ordered maintenance has strict duration and amount caps. Indiana similarly restricts alimony to rehabilitative support capped at 3 years. Kansas limits support to 121 months. Several other states, including Utah and New Hampshire, impose duration caps tied to marriage length. However, states like New Jersey, North Carolina, West Virginia, Oregon, and Connecticut continue to allow permanent or indefinite support for long marriages with significant income disparity. Reform efforts remain active in many of these states, so the landscape continues to evolve.
- Formula — The state has a statutory formula that calculates duration (and sometimes amount) based on the length of the marriage. Outcomes are more predictable, though courts can still deviate.
- Advisory guidelines — The state has non-binding guidelines that courts commonly follow. Provides a framework but allows flexibility.
- Cap — Duration is capped at the length of the marriage or some other limit, but the amount is discretionary.
- Judicial discretion — No formula or guidelines. The judge considers statutory factors and determines both amount and duration. Outcomes vary widely depending on the facts and the judge.
Important context
Before reviewing the state-by-state table, keep these key points in mind:
Federal tax treatment changed in 2019. Under the Tax Cuts and Jobs Act (TCJA), for divorce agreements executed after December 31, 2018, alimony payments are no longer deductible by the payer and not taxable income to the recipient at the federal level. This changed the economics of spousal support for everyone, regardless of state. For divorces finalized before 2019, the old rules (payer deducts, recipient pays tax) still apply unless modified.
The table below shows general duration approaches, not amounts. Alimony amounts depend on income, need, standard of living, and many other factors that vary by case. Duration is more structured in some states, which is why it is the focus here.
These are guidelines, not guarantees. Even in states with formulas, courts can deviate based on the specific facts of a case. In states with judicial discretion, outcomes can differ significantly from judge to judge. Treat this as a starting point for understanding your state's framework, not as a prediction of your outcome.

Now that you've seen how your state compares, calculate your estimated alimony using your specific income and marriage details.
Knowing your state's formula is the starting point — but formulas don't tell you whether the amount actually covers your expenses for the next 20 years. DivorceSmart Pro runs your state's formula against your real expenses and projects the result forward so you can identify where gaps may appear.
Key patterns across states
States with statutory formulas
A handful of states — including Massachusetts (M.G.L. c.208 s.49), Illinois (750 ILCS 5/504(b-1)), Florida (SB 1416), Texas (Tex. Fam. Code s.8.054), Kansas (K.S.A. 23-2904), Delaware (13 Del. Code s.1512), and New Hampshire (RSA 458:19-a) — have enacted statutory formulas that tie alimony duration to the length of the marriage. These formulas provide more predictability, though courts can still deviate in unusual circumstances.
States that have reformed alimony recently
Florida made headlines in 2023 by abolishing permanent alimony entirely (SB 1416, effective July 1, 2023). Massachusetts enacted the Alimony Reform Act in 2011, creating duration brackets based on marriage length. Several other states have considered similar reforms. The trend in recent years has been toward more structured, time-limited alimony, though many states still allow indefinite support for long marriages.
The 20-year marriage threshold
Across many states, the 20-year mark is a significant threshold. In Massachusetts, marriages of 20+ years may result in indefinite alimony. In New Jersey, 20+ years opens the door to permanent alimony. In Florida, 20+ years triggers the highest durational percentage (75% of marriage length). If your marriage is near the 20-year mark, the timing of your divorce filing could meaningfully affect your alimony outcome.
Restrictive vs. generous states
Texas and Indiana are among the most restrictive states for alimony. Texas caps court-ordered maintenance at $5,000/month and limits duration to 5–10 years. Indiana limits rehabilitative alimony to 3 years unless a spouse is incapacitated. On the other end, states like New Jersey, North Carolina, Oregon, and West Virginia still allow permanent or indefinite maintenance, particularly for long marriages with significant earning disparities.
