Spousal support payments are not taxable or deductible in California for divorce or separation agreements signed on or after January 1, 2026. For agreements signed between January 1, 2019, and December 31, 2025, the person paying still deducts alimony payments on the California return and the recipient spouse still reports them as state income, even though neither applies under federal law. For agreements signed before 2019, the old tax treatment applies at both levels: the payer deducts, the recipient reports.
The date on your agreement decides which rule you follow. That single fact is now the most important tax question in a California divorce, and it is the one most people get wrong.
Spousal Support Tax Rules Changed Twice: Federal in 2019, California in 2026
For most of the last century, spousal support (what the IRS calls alimony) worked the same way everywhere. The person paying took a tax deduction for every dollar of alimony paid. The former spouse receiving it reported every dollar as alimony income on their income tax return. Because the payer was usually in a higher tax bracket, the deduction shifted income to the lower bracket and the family as a whole paid less tax. That tax savings was built into almost every support negotiation.
The federal Tax Cuts and Jobs Act ended that arrangement. The federal rules changed for any divorce decree or separation agreement executed after December 31, 2018: alimony paid is no longer deductible, and alimony received is no longer counted as income on federal tax returns. The same rule covers separate maintenance payments made under a separate maintenance decree. Agreements signed before that date were grandfathered and keep the old treatment, unless they are later modified and the modification specifically adopts the new rule.
California did not follow. From 2019 through 2025, the state kept the California alimony deduction for the payer and required the recipient to report alimony as taxable income for California purposes. The same payment was not deductible on the federal return but was still considered taxable income on the Form 540, which forced California taxpayers to treat it two different ways on two different returns.
That gap closed on January 1, 2026. Senate Bill 711, the Conformity Act of 2025, brought California in line with the federal treatment for agreements executed on or after that date. The Franchise Tax Board confirmed the change in its February 2026 Tax News and updated its alimony guidance to match.
Which Spousal Support Tax Rule Applies to You: The Three Agreement Dates
Everything turns on when your divorce or separation instrument was executed. “Executed” means signed and entered as an order or judgment, not the date you separated or the date you filed.
Agreements signed before January 1, 2019
Federal: payer deducts, recipient reports income.
California: payer deducts, recipient reports income.
Both returns match. Nothing changed for you in 2019 or 2026.
Agreements signed January 1, 2019 through December 31, 2025
Federal: no deduction for the payer, no income to the recipient.
California: payer deducts on Schedule CA, recipient reports on Schedule CA.
This is the split-treatment group. Under California law the payer gets a state deduction but no federal deduction. The recipient owes California tax on support but no federal tax. Both spouses need a Schedule CA adjustment on every tax return, and beginning with the 2025 tax year the FTB requires you to list the month and year your agreement was executed on that schedule.
Agreements signed on or after January 1, 2026
Federal: no deduction, no income.
California: no deduction, no income.
Spousal support payments are tax-neutral at both levels. The payer pays with after-tax dollars. The recipient keeps every dollar. There is nothing to deduct, nothing to report, and no Schedule CA adjustment.
Pre-2026 agreements that get modified
A modification does not automatically move you into the 2026 rule. A pre-2026 order modified after January 1, 2026 keeps its original California treatment unless the modification expressly states that the SB 711 amendments apply. The same logic applies at the federal level for pre-2019 orders. If you are modifying an existing order, this one sentence in the modification controls thousands of dollars in tax, and it should be a deliberate choice, not an accident
Who Pays Tax on Spousal Support in California: Payer vs. Recipient
If you pay spousal support
Under a 2026 or later agreement, you get no deduction anywhere. The federal rules treat alimony payments as a personal expense, the same as rent or groceries, and California now does the same. A $4,000 monthly support order costs you $4,000 in after-tax income. If you are in a combined federal and California marginal bracket near 45 percent, you need roughly $7,300 of gross earnings to fund that payment. Under a 2019 to 2025 agreement, you still deduct the $4,000 on your California return, which recovers part of the cost at the state level only. Under a pre-2019 agreement, you deduct it on both returns.
If you receive spousal support
Under a 2026 or later agreement, support is not considered income. You owe nothing on it, federal or state, and it does not count toward your adjusted gross income for other purposes. Under a 2019 to 2025 agreement, you still report alimony received as California income and pay state tax on it. Under a pre-2019 agreement, you report the alimony income on both returns.
Temporary spousal support vs. long-term support
Temporary support ordered while the case is pending and long-term support ordered at judgment follow the same tax rule. What matters is the date the order was executed, not whether it is temporary or permanent. A temporary order entered in December 2025 and a judgment entered in March 2026 can fall under different California rules in the same case.
Which Payments Qualify as Alimony Under Federal and California Law
Not all payments between former spouses are considered alimony. The deduction and income rules above apply only to certain payments that meet the alimony definition, and that test matters most for agreements executed before January 1, 2026, where the payer still deducts on the California return (and on both returns for pre-2019 agreements). Whether alimony taxation applies depends on how the payment is structured, not on what the parties call it.
To qualify, the payment must be required by a divorce decree, a separate maintenance decree, or a written separation agreement. Voluntary payments made outside a court order or written agreement do not qualify, no matter how regular they are. The payment must be made in cash or its equivalent to or for a former spouse, and the obligation must end at the recipient’s death. The spouses must file separate tax returns and, once legally separated or divorced, must live in separate households.
Noncash property settlements, lump-sum payments that divide community property, and payments to keep up property the payer still owns are not alimony. Child support is never alimony. A spousal support order that bundles several kinds of payments should spell out which portion is support, because each piece has different tax impacts.
How the 2026 Spousal Support Tax Change Affects Negotiations
Removing the deduction does not change how much the paying spouse earns or how much the receiving spouse needs. It changes how much of the payer’s income is left after tax, and that shows up in the numbers. Tax neutrality does simplify one part of the negotiation: neither side has to model the other’s bracket to understand what a dollar of support is worth. But it also removes the shared savings that used to make a higher support figure easier to agree on.
California temporary support guidelines are run through tax-aware software that accounts for the deductibility of support when calculating each party’s net disposable income. With no deduction at either level, the same incomes produce a different guideline result than they did a year ago. Family Code section 4320, which governs long-term support, directs the court to consider each party’s tax consequences. Both of those mechanisms now operate without a state deduction.
In practice, this means three things. First, every support figure negotiated before 2026 that assumed a California deduction is now worth less to the payer than it was when it was calculated. Second, trading support for property has become more attractive in some cases, because a larger share of community property is an after-tax transfer with no ongoing tax drag. Third, modification requests on 2019 to 2025 orders need to be evaluated carefully, because adopting the new rule in a modification gives up the payer’s state deduction permanently.
Running those numbers correctly requires someone who reads both the Family Code and the Revenue and Taxation Code. As a Certified Family Law Specialist and licensed CPA, Charles M. Green models the after-tax result of a proposed support order in-house rather than sending the question out to a separate accountant and waiting for the answer to come back.
What Is Not Spousal Support for Tax Purposes
Several payments get confused with spousal support and don’t follow the spousal support rules.
Child support has never been deductible by the payer or taxable to the recipient at either level. SB 711 does not touch it. The child tax credit is a separate question that follows the custodial parent and the dependency rules, not the support order.
A lump-sum property settlement labeled “support” in a judgment is not spousal support for tax purposes if it is actually dividing community property. Community property income earned before the date of separation is already split between the spouses on their returns, and a payment that equalizes that division is a property transfer, not alimony. Mislabeling it can trigger a dispute with the FTB or the IRS.
Payments that continue after the recipient’s death, or payments between spouses still living in the same household, do not qualify as spousal support under the federal definition that California now follows. Payments that continue after the recipient’s death, or payments between spouses still living in the same household, do not qualify as spousal support under the federal definition that California now follows.
When to Have a CPA-Attorney Review a Support Order Before You Sign
Review before signing if any of these apply: your agreement was signed between 2019 and 2025, and either party is requesting a modification; you are deciding between a support award and a larger property share; the paying spouse has income from a business, stock compensation, or multiple states; or either party will be filing returns in a state other than California.
A support order that is correct under family law but wrong under tax law still costs real money every April. Charles M.

Frequently Asked Questions About Spousal Support and Taxes in California
Is spousal support taxable in California?
Spousal support is not taxable in California for agreements executed on or after January 1, 2026. For agreements executed from January 1, 2019 through December 31, 2025, the recipient reports support as income on Schedule CA (540) and pays California tax on it. Pre-2019 agreements follow the older rule at both levels.
Is alimony tax deductible in 2026?
Alimony is not tax deductible in 2026 for agreements executed on or after January 1, 2026, on either the federal Form 1040 or the California Form 540. Payers under 2019 to 2025 agreements still deduct alimony on the California return only. Payers under pre-2019 agreements deduct on both returns.
Does California follow the federal alimony tax rules?
California follows the federal alimony tax rules for agreements executed on or after January 1, 2026, under Senate Bill 711. California did not adopt the 2019 federal changes for agreements executed between January 1, 2019 and December 31, 2025, so those taxpayers still adjust alimony on Schedule CA each year.
Is temporary spousal support taxable?
Temporary spousal support follows the same tax rule as long-term support. The date the order was executed decides the treatment, not whether the support is temporary or permanent. A temporary order executed after December 31, 2025 is not deductible or taxable at the federal or California level.
If my divorce was final before 2019, do the old rules still apply?
The old rules still apply if your divorce agreement was executed before January 1, 2019. The payer deducts support and the recipient reports it as income on both the federal and California returns. That treatment continues unless the order is modified and the modification expressly adopts the newer rule.
Is child support taxable or deductible?
Child support is not taxable to the recipient and not deductible by the payer at either the federal or California level. That rule has never changed. Senate Bill 711 affects only spousal support, and the child support guideline calculation under Family Code section 4055 is not altered by the 2026 tax change.
