California's Senate Bill 711 eliminates the confusing split tax treatment of spousal support that has plagued divorcing couples since 2019. Starting January 1, 2026, alimony payments are neither deductible for the payer nor taxable income for the recipient at both federal AND California state levels for new agreements—creating complete tax neutrality for the first time in seven years.
Key Facts: California SB 711
| Item | Detail |
|---|---|
| What Happened | Governor Newsom signed SB 711 (Conformity Act of 2025), aligning California with federal alimony tax rules |

| Who's Affected | All new divorce and separation agreements executed after December 31, 2025 |
| Key Change | Spousal support becomes non-deductible for payers, non-taxable for recipients |

| Financial Impact | Support amounts may decrease 8-10% to account for lost tax benefit |
Why This Matters Legally
This legislation resolves a seven-year compliance nightmare that forced California divorcing couples to maintain two separate tax treatments for the same spousal support payments. For agreements signed between January 1, 2019, and December 31, 2025, payers could not deduct alimony on their federal returns but could deduct it on California state returns—requiring Schedule CA adjustments and creating audit risk for taxpayers who misunderstood the distinction.
The California Franchise Tax Board explicitly stated they "do not conform to the federal Alimony changes effective January 1, 2019, through December 31, 2025," creating what attorneys and CPAs called the "mismatch years." SB 711 finally closes this gap.
According to the FTB's legislative analysis, the bill's stated purpose is "to simplify the preparation of California income tax returns, the filing process for taxpayers, and the administration of California income tax laws."
How California Law Handles Spousal Support After SB 711
California Family Code governs spousal support calculations, while tax treatment now follows the federal Internal Revenue Code provisions established by the 2017 Tax Cuts and Jobs Act. Here's how the three eras break down:
Pre-2019 Agreements (Before December 31, 2018)
Spousal support remains fully deductible for payers and fully taxable for recipients under both federal and California law. These agreements are unaffected by SB 711 unless parties voluntarily modify them.
"Mismatch Era" Agreements (January 1, 2019 – December 31, 2025)
These agreements continue operating under split treatment: not deductible federally but deductible on California state returns. Recipients must report payments as California taxable income even though federal law excludes them. This treatment continues indefinitely unless parties modify the agreement AND explicitly state that SB 711 applies.
Post-2025 Agreements (January 1, 2026 Forward)
Complete tax neutrality applies. Spousal support is neither deductible for payers nor taxable for recipients at either federal or California state levels. No Schedule CA adjustments required—the California return simply follows the federal treatment.
The Modification Trap
Critically, modifying a pre-2026 agreement does NOT automatically switch parties to the new tax treatment. Both federal and California law require that the modification "expressly provides that Senate Bill 711 (2025-2026) amendments apply to such modification." Without this explicit language, the old split treatment continues.
Financial Impact on Support Calculations
The elimination of state tax deductibility changes the economics of spousal support negotiations. Family Law Software's analysis illustrates this with a concrete example:
For a payer earning $200,000 annually and a recipient earning $25,000:
- Payer's California state tax increases from $15,359 to $17,383 annually (approximately $2,024 more)
- Calculated spousal support decreases from $1,813 to $1,675 monthly
- This represents roughly an 8% reduction in support amounts
The logic is straightforward: when payers lose the state tax deduction, they have less disposable income to pay support. Courts and mediators factor this reduced after-tax income into guideline support calculations, resulting in lower nominal support amounts even though the recipient's after-tax benefit may remain similar.
Practical Takeaways
-
For divorces finalizing before December 31, 2025: Your agreement locks in the split tax treatment permanently unless you later modify with explicit SB 711 adoption language. Consider whether this benefits or disadvantages your situation.
-
For divorces finalizing January 1, 2026 or later: Expect support calculations to reflect the new tax neutrality. Nominal support amounts will likely be 8-10% lower than they would have been under the old deductible model, but recipients keep the full amount without state tax liability.
-
For existing agreements considering modification: Adding SB 711 adoption language is a significant decision. Higher-income payers generally benefit from keeping the old deductible treatment; recipients in higher tax brackets may prefer the new non-taxable treatment. Run the numbers with a CPA before modifying.
-
For tax preparation: The 2025 tax year (filed in early 2026) is the final year of the mismatch period for agreements signed during 2019-2025. Ensure your Schedule CA properly reflects the California deduction/inclusion that differs from your federal return.
-
For prenuptial agreements: Existing prenups that specify spousal support terms should be reviewed. Tax treatment assumptions built into those agreements may no longer reflect reality.
Frequently Asked Questions
Does SB 711 affect my existing divorce agreement?
No, existing agreements continue under their original tax treatment indefinitely. SB 711 only applies to agreements executed after December 31, 2025, or to modifications that explicitly adopt the new rules. Your pre-2026 agreement maintains the split treatment (deductible on California returns, not deductible federally) until you choose to change it.
Will my spousal support amount change in 2026?
Your existing court-ordered support amount does not automatically change. However, if you negotiate new support or modify existing support after January 1, 2026, calculations will reflect the new tax-neutral treatment—typically resulting in 8-10% lower nominal amounts since payers no longer receive the California state deduction.
Can I opt into the new tax treatment for my 2019-2025 agreement?
Yes, but only through a formal modification that explicitly states SB 711 applies. Both parties must agree, and the modification must contain specific language referencing the new law. Simply filing taxes differently without a modified agreement would be improper and could trigger audit issues.
How do I report spousal support on my 2025 California return?
For agreements executed during the 2019-2025 mismatch period, payers deduct spousal support on Schedule CA as a subtraction from federal AGI. Recipients add spousal support on Schedule CA as an addition to federal AGI. This adjustment is required because the amounts do not appear on your federal return but must appear on your California return.
Does this change affect child support?
No. Child support has always been tax-neutral—neither deductible for payers nor taxable for recipients at both federal and California state levels. SB 711 only affects spousal support (alimony) payments, bringing them into alignment with the child support treatment that has existed for decades.
