California's SB 711, chaptered as Chapter 231 of the Statutes of 2025, ends the state spousal support tax deduction for any order executed on or after January 1, 2026. Payers can no longer deduct alimony and recipients no longer report it as income on California returns, and guideline software now calculates support roughly 8-10% lower to offset the lost deduction.

Why this matters legally
SB 711 eliminates a 7-year gap between federal and California tax treatment of spousal support. The federal Tax Cuts and Jobs Act (TCJA) removed the alimony deduction for divorces finalized after December 31, 2018, but California kept its state-level deduction in place. According to Family Law Software, that split forced practitioners to run two sets of tax calculations — one federal, one state — for every California support award since 2019.
As of January 1, 2026, the split is gone. Under SB 711, spousal support paid on orders executed on or after that date is no longer deductible for the paying spouse, and it is no longer taxable income for the receiving spouse on California returns. This is a definitive change, not a proposal: the bill was chaptered as Chapter 231 of the Statutes of 2025 and applies to new and modified orders based on their execution date. Orders finalized before January 1, 2026 generally retain their existing California tax treatment unless later modified in a way that triggers the new rule.
How California law handles this
The practical mechanics run through two provisions. First, guideline temporary spousal support in California has long been calculated using formulas that assumed the payer received a tax deduction. With that deduction eliminated at the state level, family-law software vendors have recalibrated their formulas — the payer no longer gets a tax break, so the pre-tax support figure drops roughly 8-10% to reach the same after-tax outcome for both households. This adjustment is automatic within the software but discretionary for judges reviewing the numbers.
Second, Cal. Fam. Code § 4320 governs permanent (long-term) spousal support and lists the factors courts must weigh. Section 4320(j) directly requires courts to consider "the immediate and specific tax consequences to each party." Because SB 711 changes those tax consequences, judges setting or modifying support on or after January 1, 2026 must factor in that the payer no longer deducts the payments and the recipient no longer reports them as California income. Attorneys should expect courts to scrutinize the tax math on every § 4320 analysis going forward.
It is worth distinguishing temporary from permanent support here. Temporary support, typically set under local guideline formulas while a case is pending, sees the most direct 8-10% software adjustment. Permanent support under § 4320 is discretionary and fact-driven, so the effect there depends on how each judge weighs the new tax reality against the statutory factors.
Practical takeaways
-
Check your order date. The rule turns entirely on when the order is executed. Orders dated on or after January 1, 2026 lose the California deduction; orders finalized in 2025 or earlier generally keep their prior treatment unless modified.
-
Recalculate before you settle. If you negotiated a support number in 2025 assuming a deduction, that figure may no longer produce the after-tax result you expected. Ask your attorney to re-run the numbers in updated guideline software.
-
Reconsider modifications carefully. Modifying a pre-2026 order could pull it under the new tax rules. Under Cal. Fam. Code § 4320, a court reviewing a modification will weigh the current tax consequences, which may change the strategic value of reopening an award.
-
Document the tax assumptions in your settlement. Marital settlement agreements should state clearly how the parties treated the tax impact so there is no ambiguity if the order is later modified or enforced.
-
Coordinate federal and state planning. Federal treatment has been deduction-free since 2019; now California matches it. This actually simplifies planning going forward — one consistent rule — but transitional cases straddling both regimes need careful review.
If you are negotiating or modifying spousal support in California right now, the timing of your order matters more than it has in years. A qualified California family law attorney can run current guideline calculations, model the after-tax outcome for both spouses, and advise on whether to finalize before or after any relevant date.
