For divorce agreements executed on or after January 1, 2026, alimony (spousal support) is not taxable income for the recipient and not tax-deductible for the payer under both California state and federal law. Senate Bill 711, signed into law on October 1, 2025, ended California's 7-year divergence from federal tax treatment established by the Tax Cuts and Jobs Act of 2017. This change eliminates the state tax deduction that California payers previously enjoyed, reducing guideline spousal support amounts by approximately 8% to 10%.

How SB 711 Changed California Alimony Taxes in 2026
Senate Bill 711, chaptered on October 1, 2025, as Chapter 231 of the Statutes of 2025, conforms California's personal income tax treatment of spousal support to the federal Internal Revenue Code. For any divorce or separation agreement executed on or after January 1, 2026, the paying spouse cannot deduct alimony payments on their California state tax return, and the receiving spouse does not report those payments as taxable income. This eliminates the complex dual-filing system that existed from 2019 through 2025 when federal and California rules differed.
The practical impact is significant for divorce negotiations. Family law software used by California attorneys and judges now calculates guideline spousal support amounts approximately 8% to 10% lower than pre-2026 calculations. This reduction accounts for the payer losing the California state tax deduction benefit. A payer previously in the 9.3% California tax bracket who paid $5,000 monthly in support effectively paid $4,535 after the state deduction. Under SB 711, that same payer now pays the full $5,000 with no tax offset.
The Three Date Categories for California Alimony Taxation
California alimony tax treatment depends entirely on when your divorce agreement or court order was executed. Understanding which category applies to your situation is essential for accurate tax filing and financial planning.
Category 1: Agreements Executed January 1, 2026 or Later
For divorce or separation agreements finalized on or after January 1, 2026, alimony payments receive identical treatment under federal and California state law. The paying spouse cannot deduct spousal support payments on either federal Form 1040 or California Form 540. The receiving spouse excludes alimony from taxable income on both returns. No adjustments or schedules are required when filing California returns, simplifying tax preparation significantly.
Category 2: Agreements Executed January 1, 2019 Through December 31, 2025
Divorce agreements executed during this 7-year window created a split between federal and state tax treatment. Under federal law (the Tax Cuts and Jobs Act), alimony payments from these agreements are not deductible by the payer and not taxable to the recipient. However, California did not conform to federal law during this period. For California state income tax purposes, the paying spouse could still deduct spousal support payments on their California return, and the receiving spouse had to report those payments as taxable income on their California state tax return.
This dual treatment required careful tax planning. A paying spouse needed to track alimony separately for federal (no deduction) and state (deduction allowed) purposes. Recipients needed to exclude alimony from federal income but include it on their California return. This complexity is why SB 711 was enacted to bring California into conformity.
Category 3: Agreements Executed Before January 1, 2019
Divorce agreements and court orders executed before January 1, 2019, generally follow the traditional alimony tax rules. The paying spouse can deduct alimony payments on both federal and California state returns. The receiving spouse must include alimony as taxable income on both returns. These pre-2019 agreements remain grandfathered under the old rules unless specifically modified to adopt the new tax treatment.
How Modifying an Existing Order Affects Alimony Taxes
Changing an existing spousal support order does not automatically change which tax rules apply. Under Cal. Fam. Code § 4320, if your spousal support order was made before January 1, 2026, and you modify it after December 31, 2025, the original tax laws from the first order continue to apply. The only exception is if your new modified order expressly states that the SB 711 tax amendments apply to the modification.
This grandfathering provision has important strategic implications. A paying spouse with a pre-2026 California agreement who still enjoys the state tax deduction should carefully consider whether any modification is worth potentially losing that benefit. Conversely, a receiving spouse under a 2019-2025 agreement who currently pays California state tax on support might benefit from a modification that expressly adopts SB 711 rules, eliminating their state tax liability on those payments.
IRS Requirements for Deductible Alimony (Pre-2019 Agreements Only)
For those with grandfathered agreements executed before January 1, 2019, the IRS maintains specific requirements that must be satisfied for alimony to remain deductible under the old rules.
Payments must be made in cash, check, or money order. Transferring property, providing services, or making payments in kind does not qualify as deductible alimony. Payments must be required under a divorce decree, separation agreement, or court order. The document must specifically designate the payments as alimony, spousal support, or spousal maintenance. Payments cannot be designated as child support or property settlement.
The payer must report alimony on Schedule 1 of Form 1040 and must include the recipient's Social Security number or Individual Taxpayer Identification Number. Failure to include this information may result in a $50 penalty and potential disallowance of the deduction. The payer and recipient cannot file a joint return with each other and cannot be members of the same household at the time payments are made.
California Spousal Support Calculation Under Family Code 4320
California courts determine spousal support by weighing 14 statutory factors listed in Cal. Fam. Code § 4320. Unlike child support, which follows a mathematical formula, spousal support is discretionary. Judges have broad authority to weigh these factors based on the specific circumstances of each case.
The first factor examines each party's earning capacity sufficient to maintain the marital standard of living. This includes evaluating the supported spouse's marketable skills, the job market for those skills, and the time and expenses needed to acquire appropriate education or training to develop those skills. The marital standard of living serves as the reference point against which all other factors are measured.
Other critical factors include the extent to which the supported spouse contributed to the other spouse's education, training, career, or professional license during the marriage. Courts also consider the supporting party's ability to pay based on earning capacity, assets, and standard of living. The needs of each party based on the established marital standard, the obligations and assets (including separate property) of each party, and the impact of dependent children on the supported spouse's ability to work are all evaluated.
Domestic violence convictions trigger specific provisions under Cal. Fam. Code § 4324.5 and Cal. Fam. Code § 4325 that may reduce or eliminate a spousal support award. The court also has discretion to consider any other factors it determines just and equitable.
Duration of Spousal Support in California
California distinguishes between short-term and long-term marriages when determining spousal support duration. For marriages lasting less than 10 years, courts typically order support for one-half the length of the marriage. A 6-year marriage might result in 3 years of spousal support, providing the supported spouse time to become self-supporting.
For marriages of 10 years or longer, often called "long-term marriages," there is no automatic termination date. The court retains jurisdiction to modify or extend support indefinitely unless the parties agree otherwise. This does not mean support continues forever, but rather that the court maintains authority to address changing circumstances. The supported spouse's duty to become self-supporting within a reasonable time remains a factor the court considers.
California Divorce Filing Requirements and Costs
Under Cal. Fam. Code § 2320, at least one spouse must have been a California resident for 6 months and a resident of the filing county for 3 months immediately before filing the divorce petition. The residency requirement applies to only one spouse. If your spouse meets the requirements but you do not, the spouse meeting requirements can file. If neither spouse meets requirements, you may file for legal separation (which has no residency requirement) and convert to divorce once residency is established.
The filing fee for a Petition for Dissolution of Marriage in California is $435. If the other spouse files a Response, an additional $435 filing fee applies, bringing total court costs to $870 for a contested divorce. As of January 1, 2026, SB 1427 allows qualifying couples to file a single Joint Petition (Form FL-700) for one shared $435 filing fee, eliminating the need for formal service of process entirely.
Fee waivers are available for those who qualify under Judicial Council Form FW-001. Eligibility includes household income at or below 125% of federal poverty guidelines, receipt of public benefits such as CalWORKs, Medi-Cal, or CalFresh, or inability to afford basic living expenses and court fees. Process server costs range from $50 to $100 for service via county sheriff or $75 to $200 for a private process server.
Tax Planning Strategies for California Spousal Support
The SB 711 changes require divorcing California couples to recalibrate their negotiation strategies. Under the old rules, the tax deduction effectively subsidized spousal support payments, allowing payers to offer higher gross amounts knowing the after-tax cost was lower. With that deduction eliminated for 2026 agreements, payers have less financial flexibility.
For agreements executed between 2019 and 2025, strategic timing of modifications matters. A recipient currently paying California state tax on support (because they're in the 2019-2025 window) might benefit from a modification that expressly adopts SB 711 rules. However, the payer would lose their state deduction. Negotiating other terms in exchange for agreeing to adopt SB 711 treatment could benefit both parties.
Couples finalizing divorce in late 2025 had a brief window to preserve the state tax deduction by executing agreements before January 1, 2026. Those agreements remain grandfathered unless expressly modified to adopt SB 711. For those negotiating now, the tax implications are neutral since both federal and state treatment are identical.
Comparison: Alimony Tax Rules by Agreement Date
| Agreement Date | Federal Treatment (Payer) | Federal Treatment (Recipient) | CA State Treatment (Payer) | CA State Treatment (Recipient) |
|---|---|---|---|---|
| Before Jan 1, 2019 | Deductible | Taxable Income | Deductible | Taxable Income |
| Jan 1, 2019 - Dec 31, 2025 | Not Deductible | Not Taxable | Deductible | Taxable Income |
| Jan 1, 2026 or Later | Not Deductible | Not Taxable | Not Deductible | Not Taxable |
Reporting Alimony on Your Tax Returns
For 2026 agreements, tax reporting is straightforward. Neither the payer nor recipient reports alimony on their federal Form 1040. On California Form 540, no adjustments are needed since California now conforms to federal treatment. The alimony payments are tax-neutral to both parties.
For 2019-2025 agreements, the split treatment requires careful reporting. On your federal return, do not report alimony paid or received. On your California Form 540, the payer claims the deduction on Schedule CA, and the recipient adds the income on Schedule CA. This dual-track reporting continues until the agreement is modified to adopt SB 711 or the support obligation terminates.
For pre-2019 agreements, report alimony on both federal and California returns using the traditional rules. The payer deducts on Form 1040 Schedule 1 (line 19a) and California Schedule CA. The recipient includes alimony as income on Form 1040 Schedule 1 (line 2a) and California Schedule CA.
