As the year winds down, many California families begin reviewing their financial landscape. If you pay or receive spousal support, year-end is a good time to review your current orders, assess tax implications, and plan for potential changes.
How California courts calculate spousal support
Spousal support (also known as alimony) is determined using a two-part approach in California:
-
Temporary (or pendente lite) support: Calculated using a standard formula — often via court-approved software like Xspouse — based largely on each party’s income.
-
Permanent support: Determined during or after divorce proceedings, considering broader factors under Family Code §4326, such as:
-
Length of the marriage
-
Standard of living during the marriage
-
Each spouse’s earning capacity
-
Age and health
-
Domestic responsibilities and childcare
-
Courts in Riverside and San Bernardino counties typically rely on Xspouse for temporary orders but shift to a more comprehensive analysis for long-term support decisions.

Tax changes and how they affect spousal support
Since the 2018 Tax Cuts and Jobs Act, spousal support is no longer tax-deductible for the payor nor taxable income for the recipient — for agreements executed after December 31, 2018. This change:
-
Eliminates the year-end tax planning incentive for some payors
-
It can significantly affect how much support is negotiated or modified

Can spousal support be modified due to job changes or inflation?
Yes. California courts allow for modification of spousal support when there’s a material change in circumstances. Common reasons include:
-
Job loss or reduced income
-
Retirement
-
Increased income or remarriage of the supported spouse
-
Inflation is affecting the cost of living
We recently helped a Riverside father reduce his support order after losing his job and experiencing a 40% drop in income. The court found the change substantial enough to warrant a downward modification.

Year-end tips for payors and recipients
Before December 31, take time to:
-
Review your current support order with an attorney if your income or expenses have changed
-
Document any changes in financial status that could support a future modification request
-
Adjust your tax withholding if you’re paying or receiving significant support
-
Speak with a tax professional to prepare for potential filing impacts
FAQ: Spousal Support & Year-End Planning
Can I deduct spousal support on my taxes?
Only if your order was finalized before January 1, 2019. Newer orders are not deductible.
Do I need a court order to change support?
Yes. Even if both parties agree, support changes must be court-approved to be legally enforceable.
Is inflation a valid reason to modify support?
Potentially. If inflation significantly alters your cost of living or ability to meet needs, courts may consider it alongside other financial shifts.
As financial and legal conditions change, year-end is a strategic time to assess your support obligations. Whether you’re looking to reduce payments, seek additional support, or ensure compliance, legal review now can save you trouble in the new year.
