Alimony / Spousal Support Framework
Alimony (also called spousal support or maintenance) is separate from asset division. Typical amount: 20-40% of the income gap between spouses. Duration varies by state + marriage length. AAML benchmark formula: Alimony = (30% × payor's gross income) − (20% × recipient's gross income), recipient's total income (wages + alimony) capped at 40% of combined gross.
Four types of alimony: (1) Temporary (pendente lite): during proceedings. (2) Rehabilitative: enables lower-earner to gain skills — most common short marriages. (3) Durational: fixed period tied to marriage length. (4) Permanent: long marriages (usually 20+) or disability/age. Many states eliminated 'permanent' label post-2014 reforms.
Post-TCJA federal tax treatment (permanent): for divorces executed AFTER December 31, 2018, alimony is NOT deductible for payer AND NOT taxable for recipient. Major shift — removed the historical tax arbitrage favoring alimony over property settlement. Pre-2019 agreements retain old rules unless modified. California exception: SB 711 created state-level deduction for payer (CA state tax only, post-2019 agreements) — federal/state mismatch.
Alimony FAQs
How much alimony will I pay or receive?
20-40% of income gap typical. AAML formula: (30% × payer gross) − (20% × recipient gross), capped at 40% of combined gross. Example: payer earns $150K, recipient $30K: alimony = ($45K) − ($6K) = $39K/year ($3,250/month). Recipient total ($30K + $39K = $69K) is 38% of combined $180K — under 40% cap. State-specific variations apply — MA, TX, IL have different formulas.
How long does alimony last?
Short marriages (<5 years): typically no alimony OR 1-2 years rehabilitative. Mid (5-15 years): typically half the marriage length (rehabilitative or durational). Long (20+ years): indefinite or permanent in some states (NJ eliminated permanent label 2014, but durations can still be lengthy). MA formula: 50% of marriage length for 0-5 year marriages, scaling up. CA presumption: half the marriage length for marriages under 10 years.
Is alimony tax-deductible?
Federal: depends on date of divorce. Divorces executed AFTER December 31, 2018: alimony NOT deductible for payer, NOT taxable for recipient (TCJA change, permanent). Pre-2019 divorces: retained old rules (deductible/taxable) unless modified + expressly adopting new rules. California state tax: SB 711 created a state-level deduction for post-2019 agreements — mismatch with federal. Check with tax professional — complex transition rules.
Can I stop paying alimony if my ex remarries?
Usually YES — remarriage is automatic termination of alimony in most states. File motion to terminate as soon as remarriage occurs — don't unilaterally stop (could be contempt). Some states also terminate or reduce for cohabitation (living with new partner as if married) — tests vary: shared residence + financial interdependence + public hold-out as couple. CA + NJ have robust cohabitation reduction statutes.
Can alimony be modified after divorce?
YES — upon 'substantial change in circumstances'. Common grounds: (1) job loss / income reduction, (2) income increase, (3) disability / health change, (4) payer retirement at normal retirement age, (5) recipient cohabitation, (6) recipient remarriage. File motion to modify in court that issued original order. NOT retroactive — alimony owed at current rate until court modifies. File promptly on change.
What's the difference between rehabilitative and permanent alimony?
Rehabilitative: short-term support (1-5 years typical) to enable lower-earning spouse to gain education, skills, or re-enter workforce. Common for short marriages + able-bodied recipients. Durational: fixed period, typically longer (5-10 years), tied to marriage length. Permanent: long marriages or disability/age — continues until death, remarriage, or retirement. Most states have eliminated 'permanent' label post-2014 but long-duration durational alimony still common.
Does my ex-spouse's fault affect alimony?
Most states — NO (no-fault divorce). Marital misconduct (affair, DV) irrelevant to alimony amount. Exceptions — fault matters: North Carolina, Virginia, Georgia, a few others. In fault-states: proven infidelity can increase support to innocent spouse or reduce to guilty spouse. DV victims in CA get mandatory enhancement under Family Code §4320(i). Consult state-specific attorney.
Is lump-sum alimony possible instead of monthly payments?
YES — 'alimony in gross' or 'lump-sum alimony'. Calculated as present value of stream of payments. Non-modifiable once paid (no future reductions possible). Advantages: financial independence, no ongoing payor-recipient relationship. Disadvantages: tax treatment varies (may be treated as property settlement, may not); recipient can't claim hardship modification. Consult tax + divorce attorney — structure matters enormously.
Is there an alimony formula in your state?
Usually not — and that is the single most misunderstood fact about spousal support. Only 8 of 51 jurisdictions bind their courts to an actual formula; in 38 the amount is up to the judge, guided by statutory factors. Where a formula or hard cap exists, it is quoted below with the statute it comes from. Rows marked “temporary only” apply while the divorce is pending, not after.
| State | Amount rule | The formula / cap | Duration | Authority |
|---|---|---|---|---|
| Alabama | Judge's discretion | No formula — statutory factors | Rehabilitative alimony: limited duration not to exceed 5 years absent extraordinary circumstances, aimed at enabling the recipient to acquire the ability to preserve the marital economic status quo. Periodic alimony: eligibility period not to exceed the length of the marriage (measured to the date of filing of the divorce complaint), UNLESS the marriage lasted 20 years or longer, in which case there is no statutory time limit — subject to a court finding that deviation from these time limits is equitably required. | Ala.

| Arizona | Binding formula | A.R.S. §25-319(B), amended eff. 9/24/2022, directs the Arizona Supreme Court to establish Spousal Maintenance Guidelines; 'The amount of spousal maintenance resulting from the application of the guidelines shall be the amount of spousal maintenance ordered by the court, unless the court finds in writing that applying the guidelines would be inappropriate or unjust' — a rebuttable statutory presumption. The guideline AMOUNT itself is produced by the official Spousal Maintenance Calculator (self-sufficiency-based, using U.S. BLS Consumer Expenditure Survey per-capita data), not a simple hand percentage; deviating from the resulting amount range requires written findings addressing the guideline's factor list. | Per the Arizona Spousal Maintenance Guidelines (Ariz. Sup. Ct. Admin. Order 2023-119, amended AO 2025-101 eff. 9/1/2025), duration RANGES apply by marriage length (months from marriage date to service of the dissolution/legal-separation petition), and the statute does not authorize deviation from these ranges: <24 mo → 3-12 mo; 24-<60 mo → 6-36 mo; 60-<120 mo → 6-48 mo; 120-<192 mo → 12-60 mo; ≥192 mo → 12 months up to 144 months (12 years) or 50% of the marriage length, subject to the 'Rule of 65' (if the party seeking maintenance is ≥42 years old, the marriage is ≥192 months, and that party's age plus marriage-length-in-years is ≥65, the duration is fully discretionary/case-by-case with no fixed range). | A.R.S. § 25-319(B) (2022 Ariz.

| California | Advisory guidelinetemporary only | Temporary support only: courts use county guideline calculators (e.g. the Santa Clara guideline); post-divorce support is discretionary under Fam. Code § 4320 | For POST-DIVORCE support (Fam. Code §4320(l), a separate regime from the temporary formula): 'the goal that the supported party shall be self-supporting within a reasonable period of time. Except in the case of a marriage of long duration as described in Section 4336, a "reasonable period of time" for purposes of this section generally shall be one-half the length of the marriage.' This is a soft guideline, not a hard cap — the court retains full discretion to order more or less. For marriages of 'long duration' (presumptively ≥10 years under Fam. Code §4336), there is no automatic termination date and the court retains jurisdiction indefinitely. | Cal. Fam. Code §§ 3600, 4320(l), 4336 |
| Colorado | Advisory guideline | If marriage duration ≥3 years and combined annual adjusted gross income ≤$240,000: guideline amount = 40% of the parties' combined monthly adjusted gross income minus the lower-income party's monthly adjusted gross income (floored at $0 if negative). If the award is NOT taxable to the recipient/deductible by the payor, the guideline amount is instead 80% of that figure when combined monthly income ≤$10,000, or 75% when combined monthly income is $10,001-$20,000 (no reduction specified above $20,000/mo in the statute's percentage brackets). Above $240,000 combined annual income, this amount methodology does not apply and the court instead uses the general factors list (C.R.S. §14-10-114(3.5)). | Guideline term (in whole months) is read off a statutory table keyed to marriage duration (in whole months) via a rising percentage-of-marriage-length multiplier, e.g.: 36 mo marriage → 31.00% → 11 mo term; 90 mo → 40.00% → 36 mo term; 150 mo (12.5 yrs) and beyond → capped at 50.00% of marriage-months as the term. For marriages over 20 years (240 mo), the court may award a term of years or an indefinite term, but may not award less than the 20-year guideline term without specific findings supporting a reduced term. | C.R.S. § 14-10-114(3)(b), (e) |

Applies only where the parties' combined GROSS income is under $500,000 and the payor has no support obligation from a prior relationship; if guideline maintenance plus child support would exceed 50% of the payor's net income, the court may switch to non-guideline maintenance instead. 750 ILCS 5/504(b-1)(1)(A). | Guideline duration = length of the marriage at filing, multiplied by a fixed statutory factor: <5yr=.20; 5-<6=.24; 6-<7=.28; 7-<8=.32; 8-<9=.36; 9-<10=.40; 10-<11=.44; 11-<12=.48; 12-<13=.52; 13-<14=.56; 14-<15=.60; 15-<16=.64; 16-<17=.68; 17-<18=.72; 18-<19=.76; 19-<20=.80.

Income is defined per the Massachusetts Child Support Guidelines, but EXCLUDES: (1) capital gains/dividend/interest income derived from assets already equitably divided under c.208 §34, and (2) gross income already counted for a child support order.

Gross income (as defined in RSA 458:19, V) is first reduced by amounts actually paid for child support/alimony and health-insurance or other specified expenses for the other party; the payee's income is then increased by any child support received for the parties' joint children.

| Tennessee | Judge's discretion | No formula — statutory factors | No mathematical duration formula. Four types: rehabilitative alimony (time-limited, to reach earning capacity comparable to marital standard of living); alimony in futuro (periodic, until death or remarriage of recipient — used only when rehabilitation is not feasible); transitional alimony (fixed term, for a spouse who needs short-term adjustment help but not rehabilitation); alimony in solido (fixed lump/total sum, generally non-modifiable except by agreement). Statute states explicit legislative preference for rehabilitative and transitional (time-limited) alimony over long-term alimony in futuro whenever economic rehabilitation is feasible. | Tenn. Code Ann. § 36-5-121 |
| Texas | Hard cap only | Maintenance may not exceed the lesser of $5,000 per month or 20% of the paying spouse's average monthly gross income (Tex. Fam. Code § 8.055(a)). This dollar/percentage ceiling was set by 2011 amendment (Acts 2011, 82nd Leg., R.S., H.B. 901, § 4, eff. Sept. 1, 2011), raising it from the prior $2,500/20% cap. | Duration capped by marriage length under § 8.054: 10–<20 yrs → maintenance may not continue more than 5 years after the order; 20–<30 yrs → not more than 7 years; 30+ yrs → not more than 10 years. Courts must limit duration to the shortest reasonable period unless the recipient's ability to earn sufficient income is substantially or totally diminished due to a physical or mental disability, duty as custodian of an infant/young child requiring substantial care, or another compelling impediment — in which case indefinite maintenance with periodic review is possible (linked to eligibility under § 8.051(2)(A)/(C)). | Tex. Fam. Code §§ 8.054–8.055 (current version; amount cap set by 2011 amendment, in force since Sept. 1, 2011) |
| Utah | Judge's discretion | No formula — statutory factors | Except where the court finds extenuating circumstances or good cause (found at any time before termination), alimony may not be ordered for a period longer than the length of the marriage (Utah Code § 81-4-502(7)). Time a party pays temporary alimony during the pendency of the divorce counts toward this duration cap. This is a real statutory ratio rule (duration ≤ marriage length) even though the AMOUNT itself remains fully discretionary. | Utah Code § 81-4-502 (current as of Jan. 1, 2025; recodified from former Utah Code § 30-3-5 as part of the 2024/2025 Domestic Relations Code recodification, S.B. 119 (2025)) |
| Vermont | Advisory guideline | Non-binding statutory guideline table at 15 V.S.A. § 752(b)(9), listed as one of nine non-exclusive factors: suggested support = X% of the difference between the parties' gross incomes, where X depends on marriage-length band — 0 to <5 yrs: 0-16%; 5 to <10 yrs: 12-29%; 10 to <15 yrs: 16-33%; 15 to <20 yrs: 20-37%; 20+ yrs: 24-41%. | Same guideline table (non-binding) suggests duration as a % of marriage length, by the same bands: 0 to <5 yrs → no alimony or short-term alimony up to 1 year; 5 to <10 yrs → 20-50% of marriage length (1-5 yrs); 10 to <15 yrs → 40-60% (4-9 yrs); 15 to <20 yrs → 40-70% (6-14 yrs); 20+ yrs → 45%+ (9-20+ yrs). No presumption attaches; the statute requires the award be 'in such amounts and for such periods of time as the court deems just, after considering all relevant factors, including' this guideline — courts have 'broad discretion' per case law and need not make findings to deviate. | 15 V.S.A. § 752(b)(9) (as amended through 2019, No. 131 (Adj. Sess.), § 300) |
| Virginia | Binding formulatemporary only | Presumptive pendente lite (temporary, pre-final-decree) spousal support = difference between (a) 26% of payor spouse's monthly gross income and 58% of payee spouse's monthly gross income, if the parties have minor children in common; or (b) 27% of payor's monthly gross income and 50% of payee's monthly gross income, if no minor children in common. Rebuttable presumption — court may deviate for good cause shown (e.g. current financial circumstances, tax-exemption impact). Applies identically in both Juvenile & Domestic Relations District Court (§ 16.1-278.17:1) and Circuit Court (§ 20-103(E)-(J)). | No formula for the general award: court decrees periodic payments for a defined duration, periodic payments for an undefined duration, a lump sum, or any combination, 'in its discretion' (§ 20-107.1(C)), based on 13 non-exclusive factors (obligations/needs/resources, standard of living, marriage duration, earning capacity/education, contributions, fault where relevant, etc., § 20-107.1(E)). Contested cases require written findings identifying which factors supported the ruling (§ 20-107.1(F)). One partial exception: if the court reserves a party's right to receive support in the future rather than deciding it now, there IS a rebuttable statutory presumption that the reservation period equals 50% of the time between the date of marriage and the date of separation (§ 20-107.1(D)) — a real duration formula, but only for this specific 'reservation of support' mechanism, not for ordinary awards. | Va. Code § 20-107.1; temporary: Va. Code § 16.1-278.17:1 (2007, c. 909; amended 2020, c. 651) and Va. Code § 20-103(E)-(J) (parallel circuit-court version) |

Method. Each row cites the current statute (checked against post-2019 amendments — several states rewrote their formulas after the federal tax reform). “Advisory guideline” means a published formula courts may consult but need not follow. Statutes change; the linked authority controls if this table ever disagrees with it. Legal information, not legal advice.
