The state tax deduction that California spousal support payers have relied on for years is gone. For any support order dated January 1, 2026 or later, payers can no longer deduct payments on their California return, and recipients no longer report those payments as state income. That’s not just a tax-time inconvenience. It changes how support gets negotiated, calculated, and structured from the moment a divorce begins.
At Joel S. Seidel & Associates, we’ve guided San Fernando Valley clients through decades of California family law changes, with over 60 years of combined legal experience across our team. SB 711 is one of the more consequential developments we’ve seen in spousal support law in recent years, and it affects residents whose cases are heard at the Van Nuys Courthouse in ways that aren’t widely understood. Whether you’re negotiating a new order, holding a pre-2026 agreement, or considering a modification, the financial picture looks different than it did even six months ago.
What SB 711 Actually Changed
Governor Newsom signed SB 711 on October 1, 2025. Effective January 1, 2026, it amended the California Revenue and Taxation Code so the state now mirrors the federal treatment of alimony established by the Tax Cuts and Jobs Act (TCJA), the 2017 federal law that eliminated the alimony deduction for federal tax purposes starting in 2019. Since 2019, a gap had existed between federal and California treatment: payers couldn’t deduct spousal support on their federal return but could still claim it on California Form 540, while recipients had to report it as California taxable income even though it was excluded from federal gross income. SB 711 closes that gap. The California Franchise Tax Board (FTB) has confirmed that for support orders dated on or after January 1, 2026, alimony payments are non-deductible for payers and excluded from gross income for recipients on all state filings. Both levels are now fully tax-neutral.
Which Orders the Law Affects and Which It Doesn’t
Three distinct tax regimes now coexist in California depending on when the support order was entered. Understanding which category applies to your order is the starting point for any financial analysis.
- Orders entered before January 1, 2019: These follow traditional rules at both levels. The payer deducts and the recipient reports income on federal and California returns alike.
- Orders entered between January 1, 2019 and December 31, 2025: These remain on the split system. No federal deduction for the payer, no federal income for the recipient, but the California deduction and California income treatment both remain active.
- Orders entered on or after January 1, 2026: Fully tax-neutral at both levels. No deduction, no taxable income, at either the federal or state level.
SB 711 doesn’t automatically convert existing orders. A pre-2026 support order continues under its original tax treatment unless the parties modify it with language that expressly states SB 711 applies. Modifying a pre-2026 order after January 1, 2026 without invoking SB 711 in the modification language keeps the old split treatment in place; including that language switches the order to the new tax-neutral rules. That choice is a negotiation point, not an automatic outcome, and getting it wrong is difficult to undo.
How SB 711 Affects Support Calculations
The tax shift has a direct impact on how support amounts are computed. California courts use the DissoMaster program to calculate guideline figures for temporary spousal support. Because the payer no longer receives a state tax deduction on support payments, their after-tax income is effectively lower than the DissoMaster would have reflected under prior law. Family law practitioners are seeing guideline figures come out roughly 8 to 10 percent lower than pre-2026 formulas produced under similar income assumptions.
For permanent support, courts apply the multi-factor analysis under California Family Code Section 4320, which governs long-term spousal support determinations. Section 4320(j) specifically requires courts to consider the immediate and specific tax consequences to each party. Under the new rules, eliminating the deduction increases the real after-tax cost of every dollar the payer sends while reducing the recipient’s tax burden on every dollar received. Any temporary support figures run before January 1, 2026 should be recalculated using updated tax inputs before they’re used in settlement discussions or court presentations.
What This Means for Payers & Recipients Right Now
The practical financial impact differs depending on which side of the support obligation you’re on.
Payers Under a New or Pending Order
Each dollar of spousal support now costs the full nominal amount with no state tax offset. A payer in California’s 9.3% bracket paying $5,000 per month would have saved approximately $465 monthly under the prior California deduction. That benefit is gone for 2026 orders. Support negotiations that don’t account for this shift will produce agreements that feel very different once the payer’s net cash position is calculated correctly.
Recipients Under a New or Pending Order
Payments received under a 2026 order are fully tax-free at both levels. That means a lower gross support amount can produce the same net monthly income that a higher pre-2026 figure would have delivered after state tax. A recipient’s attorney who understands this dynamic will approach support negotiations differently than one applying pre-2026 assumptions.
Payers Under a Pre-2026 Order
The loss of the deduction on new orders may constitute a material change in circumstances supporting a modification petition under California Family Code Section 3651. Courts evaluate such petitions individually, and the tax law change alone does not determine the outcome of a modification request. For payers whose support obligations now look significantly different on an after-tax basis, a review of whether modification is appropriate is worth having.
Negotiation & Settlement Strategy Under the New Rules
Settlement discussions that began in 2025 and are concluding now need to be rebuilt on post-SB 711 net income figures. Support amounts, duration, and property division that were balanced under the old tax assumptions may no longer reflect the actual financial realities of both parties. An agreement that looked fair in October 2025 may underpay or overpay once the deduction disappears from the calculation.
Several structural tools can help offset the impact of the changed after-tax economics. Property division allocations, retirement account distributions, and lump-sum support buyouts all interact with the support obligation in ways that go beyond the tax change itself. When the situation warrants it, we work with forensic accountants and vocational evaluators to help the court and opposing counsel understand the full financial picture, including post-SB 711 after-tax impacts for both parties. A marital settlement agreement drafted with those figures in mind gives both spouses a clearer picture of what they’re actually agreeing to.
One detail that belongs in every 2026 settlement agreement or modification: if the parties intend the new tax-neutral rules to apply, that election should appear explicitly in the document. Ambiguity about which tax regime governs a modified or newly drafted order is the kind of drafting problem that surfaces years later at tax time, usually in a way that benefits nobody.
Getting the Classification Right Matters
The financial consequences of misclassifying an order (or omitting key language from a modification) can compound over years of payments. For Northridge residents whose cases are handled at the Van Nuys Courthouse, working with attorneys who understand both the legal mechanics of SB 711 and the local court context makes a meaningful difference in how these agreements are structured and what they actually produce financially.
