Taxes can make alimony complicated—especially in California, where the rules don’t always match up with federal laws. With major changes to the tax code coming in 2025, understanding how alimony is taxed has never been more important.
Whether you’re paying or receiving alimony, knowing how these rules impact your finances is key to making informed decisions.
The Evolution of Alimony Tax Law
Consider two California residents paying identical amounts in alimony—one divorced in 2018, the other in 2020. While their state taxes remain the same, their federal tax situations differ dramatically due to recent legislative changes.
Before 2019: The Old Rules
Under the old federal system, alimony payments were:
- Deductible for Payers: This meant that if you were paying alimony, you could reduce your taxable income by the amount you paid, lowering your overall tax bill.
- Taxable for Recipients: The alimony you received was considered taxable income, similar to a paycheck, and you had to report it on your tax return.
This setup often benefited both parties, encouraging higher alimony payments since the payer saved on taxes, and the recipient’s lower tax bracket meant smaller tax bills.
The 2019 Tax Cuts and Jobs Act (TCJA)
The Tax Cuts and Jobs Act (TCJA) was signed into law on December 22, 2017, with many of its provisions, including significant changes to alimony tax treatment, taking effect on January 1, 2019.
Under the TCJA, alimony agreements finalized after December 31, 2018, no longer qualify for federal tax deductions. Alimony payments are now treated like personal expenses, meaning:
- Payers cannot deduct payments on their federal tax returns.
- Recipients no longer need to report alimony as taxable income.
This change simplified tax filing for recipients but increased the financial burden for payers, who lost a substantial tax benefit that often influenced divorce negotiations.
How Alimony Is Taxed Today
The way alimony is taxed depends on two things: federal laws and California state rules. Here’s what the current system looks like:
Federal Alimony Tax Rules
The federal government follows two sets of rules based on when your divorce agreement was finalized:
- Before 2019: Alimony is tax-deductible for payers and taxable income for recipients.
- After 2018: Alimony is not deductible for payers or taxable for recipients. This shift came from the 2019 Tax Cuts and Jobs Act (TCJA).
California Rules for Spousal Support Taxes
California didn’t adopt the federal changes. Instead, it sticks with the pre-2019 system:
- Payers can deduct alimony on their state tax returns, no matter when the agreement was finalized.
- Recipients must report alimony payments as taxable income on California state returns.
Why This Dual System Matters
If you’re dealing with both federal and California taxes, you need to calculate them separately. This dual taxation setup can lead to filing errors and unnecessary penalties if records aren’t kept properly.
Seeking guidance from a tax professional can help simplify this process and ensure compliance.
What’s Changing in 2025?
Several tax provisions from the TCJA are set to expire, which could reshape how alimony payments are taxed and calculated. Here are the big ones:
SALT Deduction Cap Expiration
Currently, federal law caps state and local tax (SALT) deductions at $10,000 annually. For Californians who pay substantial property and state income taxes, this cap has created a heavier federal tax burden, often straining financial resources further.
But with the SALT cap set to expire in 2025, there’s an opportunity to rethink your tax strategy—especially when it comes to alimony.
If you’re paying $15,000 a month in alimony and $30,000 annually in state and property taxes. Under today’s rules, you can only deduct $10,000 of those taxes on your federal return.
When the cap expires, however, you could deduct the entire $30,000, reducing your federal tax liability significantly.
This change could free up more disposable income, which might influence how alimony payments are negotiated or recalculated in the future.
Qualified Business Income Deduction (QBI) Ends
The QBDI gives small business owners a 20% deduction on qualified business income. This deduction reduces the taxable amount used in spousal support calculations, often resulting in lower alimony obligations.
Once this deduction disappears in 2025, business owners may face higher tax burdens, potentially impacting their ability to meet alimony obligations.
Alimony Modifications
As financial conditions shift under the new tax rules, courts may be more willing to revisit alimony agreements. If rising taxes impact your ability to make payments, requesting a modification could help ease the strain.
However, changing an alimony agreement can also impact your taxes, so it’s important to understand the rules before making any updates. Here’s what to keep in mind:
- For Pre-2019 Agreements: If you modify an agreement finalized before 2019, it might lose its old tax treatment (deductions for payers, taxes for recipients) unless it’s explicitly stated that the original rules still apply. Without this clarification, the IRS may apply the newer rules.
- For Post-2018 Agreements: Changes to these agreements generally stick with the newer federal rules. That means no deductions for payers and no income reporting for recipients.
Documentation Requirements for Tax Compliance
California’s dual tax system makes proper record-keeping a must if you’re paying or receiving alimony. Without clear documentation, you risk audits, penalties, or missed deductions. Here’s what you’ll need to stay compliant:
Federal Requirements
To satisfy federal tax authorities, you’ll need the following:
- Divorce or Separation Agreement: Ensure your agreement clearly states alimony payment terms, amounts, and conditions. If modifications are made, include those records as well.
- Proof of Payment: Retain records such as canceled checks, bank statements, or digital payment receipts that show alimony payments have been made. These are essential if the IRS requests proof.
- Residence Information: For alimony to qualify, both parties typically need to maintain separate households. Keep records of housing costs or lease agreements to demonstrate this.
- Death Provisions in the Agreement: Alimony payments must terminate upon the recipient’s death to qualify as alimony under IRS guidelines. Ensure this is explicitly stated in your agreement.
California-Specific Requirements
- Separate State Records: California allows deductions even if the IRS doesn’t. Keep clear records for state filings.
- Modified Agreements: If your agreement changes, state whether it follows the old (pre-2019) or new federal tax rules.
- XSPOUSE Reports: California courts have transitioned to using XSPOUSE software to calculate alimony, replacing the older DissoMaster™ system. Be sure to save these reports for your records, as they are vital for documentation and potential future modifications.
