California Senate Bill 711, effective January 1, 2026, eliminates the state-level tax deduction for spousal support payments, conforming California to the federal Tax Cuts and Jobs Act of 2017. Paying spouses in California can no longer deduct alimony on state tax returns, and receiving spouses no longer report it as taxable income. For a state where the median household income exceeds $95,000 and divorce rates affect roughly 160,000 couples annually, this changes the financial calculus of every support negotiation going forward.

California Was One of the Last Holdouts
California maintained its state-level alimony deduction for nearly seven years after Congress eliminated the federal version. When the Tax Cuts and Jobs Act (TCJA) took effect on January 1, 2019, it ended the longstanding federal rule allowing paying spouses to deduct alimony and requiring receiving spouses to report it as income. That federal change applied to all divorce agreements executed after December 31, 2018.
California, however, did not automatically conform. Under Cal. Rev. & Tax Code § 17201, the state selectively conforms to the Internal Revenue Code, and the legislature chose to preserve the deduction at the state level. This created a split system where California payers could still deduct spousal support on their Form 540 state return even though they could not deduct it on their federal 1040.
That split ended when Governor Newsom signed SB 711 into law. As of January 1, 2026, California fully conforms to the TCJA treatment of alimony. The California Franchise Tax Board has confirmed that spousal support payments are now non-deductible for payers and excluded from gross income for recipients on all state filings.
How This Changes Divorce Negotiations in California
The elimination of the state deduction fundamentally shifts how attorneys and mediators structure spousal support. Under the old regime, the tax deduction created a financial incentive that benefited both parties. A paying spouse in the top California income tax bracket of 13.3% could effectively reduce the real cost of every dollar of support by 13.3 cents at the state level. That savings often translated into higher gross support amounts, because the payer could afford to be more generous when the government was subsidizing part of the payment.
Consider a concrete example. A paying spouse earning $300,000 annually and ordered to pay $5,000 per month ($60,000 per year) in spousal support previously saved approximately $7,980 annually on their California state tax bill alone (at the 13.3% marginal rate). That savings is now gone. The same $60,000 payment now costs the full $60,000 after tax at the state level.
For receiving spouses, the change is a net positive on paper. Under the old rules, a recipient reporting $60,000 in spousal support as state taxable income might have owed $3,600 to $5,400 in additional California taxes depending on their bracket. That liability disappears entirely under SB 711.
The net effect, however, is that the total tax burden on spousal support shifts entirely to the payer. When support was deductible for payers and taxable for recipients, the tax hit was distributed between both parties (and often landed in a lower bracket on the recipient side). Now 100% of the tax cost sits with the paying spouse, which creates downward pressure on support amounts.
What California Family Code Says About Support Calculations
California courts determine spousal support under Cal. Fam. Code § 4320, which lists roughly 15 factors judges must consider. Among them are the tax consequences to each party, codified at Cal. Fam. Code § 4320(j). This factor now weighs differently. Courts must account for the fact that the paying spouse receives zero tax benefit from support payments at either the federal or state level.
For temporary support, most California counties use the Santa Clara guideline or similar formulas that historically factored in the tax deduction. Those formulas have already been updated at the federal level post-TCJA, but practitioners who were still adjusting for the California state deduction must now remove that variable entirely.
Modification of existing orders is governed by Cal. Fam. Code § 3651, which requires a material change of circumstances. The loss of the state tax deduction alone may constitute such a change for payers with pre-2026 California-specific support agreements that were calculated assuming the deduction would continue. Any paying spouse with an existing order should consult with their attorney about whether a modification petition is warranted.
Practical Takeaways
-
Review any pending divorce settlement. If you are currently negotiating spousal support in California and your agreement has not been finalized, recalculate all numbers without the state deduction. Agreements drafted before January 1, 2026, that assumed the deduction will overstate what the payer can actually afford.
-
Existing orders may be modifiable. Paying spouses with orders entered before 2026 that explicitly factored in the California state tax deduction should evaluate whether the loss of that deduction constitutes a changed circumstance under Cal. Fam. Code § 3651.
-
Expect lower gross support amounts going forward. Without the tax subsidy, payers have less capacity to pay, and courts weighing tax consequences under Cal. Fam. Code § 4320(j) will account for the increased after-tax cost.
-
Recipients keep more of each dollar. While gross support amounts may decrease, recipients no longer owe California income tax on the support they receive. The net-to-recipient calculation changes, and in some brackets, recipients may come out roughly even despite lower gross payments.
-
Update your financial software and tax planning. Tools like Family Law Software have already updated their California modules. Anyone using spreadsheets or older calculators for support negotiations needs to remove the state deduction variable.
Frequently Asked Questions
Does SB 711 affect spousal support orders entered before 2026?
SB 711 changes the tax treatment, not the support order itself. Orders entered before January 1, 2026, remain enforceable at the same dollar amount. However, payers who lose the state deduction may petition for modification under Cal. Fam. Code § 3651 by demonstrating a material change in circumstances. The tax impact alone could support such a petition, particularly for payers in the 9.3% to 13.3% state brackets.
Can I still deduct spousal support on my federal taxes?
No. The federal alimony deduction was eliminated by the Tax Cuts and Jobs Act for all agreements executed after December 31, 2018. California SB 711 now mirrors this federal treatment at the state level. As of 2026, spousal support is non-deductible on both federal Form 1040 and California Form 540 for all new and modified agreements.
How much will this cost paying spouses in California?
The cost depends on the payer's marginal state tax rate and the support amount. A payer in the 13.3% top bracket paying $60,000 annually in spousal support loses approximately $7,980 per year in state tax savings. A payer in the 9.3% bracket paying the same amount loses roughly $5,580 annually. These are real dollars that previously offset the cost of support.
Will California courts order lower spousal support amounts now?
California courts are required to consider tax consequences under Cal. Fam. Code § 4320(j), and the elimination of the deduction increases the after-tax cost to payers. This creates downward pressure on support amounts. While each case depends on its specific facts, attorneys and family law commentators broadly expect average gross support awards to decrease by 5% to 15% to reflect the new tax reality.
Does this affect child support calculations in California?
Child support has never been tax-deductible in California or under federal law, so SB 711 does not directly change child support calculations under Cal. Fam. Code § 4055. However, because spousal support is factored into the child support formula as part of each parent's net disposable income, a change in spousal support amounts can indirectly shift child support obligations.
