As the calendar year closes, divorcing or separating couples in California face more than emotional decisions—they also face key financial deadlines. Whether you’re deep in the divorce process or just considering separation, year-end financial planning can significantly impact your outcome.
Why timing matters in divorce
The end of the year affects everything from taxes to support calculations. Taking action before December 31 can:
-
Help you claim key tax benefits or avoid penalties
-
Freeze marital asset accumulation before year-end
-
Clarify obligations for spousal or child support in the new year
One San Bernardino client we advised was able to finalize a property agreement just before year-end, ensuring her separate income wouldn’t be counted as marital property.
Tax issues to consider
Here are some important tax-related factors divorcing couples should evaluate:
-
Filing status: Your marital status on December 31 determines how you file
-
Dependency exemptions: Decide who claims children for tax purposes
-
Spousal support deductibility: New tax rules have eliminated federal deductions for alimony
-
Asset transfers: Some transfers may have capital gains or tax consequences

Year-end strategies for asset division
Planning your division of assets by year-end can:
-
Prevent disputes over holiday spending or bonuses
-
Provide a clean cut-off for income earned and debts incurred
-
Allow for year-end valuations of retirement accounts and investments
If both parties agree, you can sign a marital settlement agreement even if the divorce won’t be finalized until the new year.
How to prepare before December 31
To approach year-end wisely:
-
Review all financial documents: Tax returns, bank statements, credit reports
-
Track income and spending: Especially for joint accounts or upcoming bonuses
-
Consider temporary orders: For support or control of assets
-
Meet with legal and financial advisors: To time filings and agreements properly
-
Prioritize agreement on key financial issues: Even partial settlements help
