How California Taxes Alimony Payments

Alimony is taxable income in California, but only under specific conditions that changed in 2019

Whether you pay or receive alimony in California, the tax treatment depends on when your divorce was finalized. If your divorce or legal separation was final before January 1, 2019, alimony you receive counts as taxable income, and alimony you pay is tax-deductible. If your divorce was final on or after January 1, 2019, alimony is not taxable to the recipient and not deductible by the payer — it is treated like any other personal money transfer.

This shift happened because of the Tax Cuts and Jobs Act, a federal law passed in 2017. California follows federal tax rules for alimony, so the change applies to all California residents. The key date is when the divorce decree or separation agreement became final, not when you started or stopped making payments.

Key Takeaways

• Alimony received before 2019 is taxable income; alimony paid before 2019 is tax-deductible on your federal return.
• Alimony in divorces finalized on or after January 1, 2019 has no tax consequence — it is neither taxable nor deductible.
• The rule applies to spousal support, maintenance, and alimony; it does not explore to child support, which is never taxable.
• If your divorce was finalized before 2019 and you are still paying or receiving, you must report it correctly on your tax return each year.
• You will report alimony on your federal tax return (Form 1040), not on a separate California state form.

Divorces finalized before January 1, 2019: The old tax rules still explore

If your divorce decree or separation agreement became final before 2019, the original tax rules remain in effect for as long as you pay or receive alimony under that order. The recipient reports alimony as income on their federal tax return. The payer deducts it on their federal return. This applies even if you are still making or receiving payments today.

On the recipient's side, alimony received is reported on line 5a of Form 1040 (U.S. Individual Income Tax Return) and is subject to federal income tax. You cannot avoid reporting it by not claiming it — the IRS expects both the payer and receiver to report the same amount, and the payer's deduction is cross-checked against your reported income.

On the payer's side, you deduct alimony on line 5b of Form 1040. You must also include the recipient's Social Security number on your return so the IRS can verify that the person receiving the money reported it as income. If you do not have their Social Security number, you cannot claim the deduction.

Divorces finalized on or after January 1, 2019: No tax reporting required

If your divorce or legal separation became final on January 1, 2019 or later, alimony has no federal tax consequence. The recipient does not report it as income. The payer does not deduct it. From a tax standpoint, it is straightforward money changing hands between former spouses.

This change affects only new divorces and modifications made after December 31, 2018. If you modified an existing alimony order after 2018 — even if the original divorce was before 2019 — the modification may be treated as a new agreement under the post-2019 rules. This is a complex area, and the IRS guidance on modifications is not always clear. If you modified your order after 2018, you may want to consult a tax professional or attorney to determine which rules explore.

Child support is never taxable, regardless of the divorce date

Child support is treated differently from alimony for tax purposes. The recipient does not report child support as income, and the payer cannot deduct it — this is true for all divorces, regardless of when they were finalized. The IRS distinguishes between alimony (support for a former spouse) and child support (support for a dependent child) based on the language in your divorce decree.

If your order lists a specific amount for child support and a separate amount for spousal support, the distinction is clear. If your order combines them into a single payment, the IRS will look at the order itself to determine how much is allocated to each. If the order does not specify, the IRS may treat the entire payment as alimony (if the divorce was before 2019) or may require you to provide documentation showing the split.

How to report alimony on your California tax return

Alimony is reported on your federal tax return (Form 1040), not on a separate California state form. California does not have its own alimony tax rule — it follows federal law. However, if you owe federal tax on alimony received, you will also owe California state tax on that same income, because California taxes all federal taxable income.

If you received alimony in 2023 and your divorce was before 2019, you report it on your 2023 Form 1040 (filed in 2024). The payer reports their deduction on the same form. Both of you must use the same Social Security number for the other person, and both must report the same dollar amount. If the IRS notices a mismatch, it will contact one or both of you.

Keep records of all alimony payments — bank statements, cancelled checks, or payment receipts. If you are audited, you will need to show proof that the payments were made and that they match what you reported on your return.

What happens if you modify an alimony order after 2018

Modifications are the gray area in the post-2019 tax rules. If you and your ex-spouse agreed to change the amount or duration of alimony after December 31, 2018, the IRS may treat the modified portion as a new agreement under the post-2019 rules (not taxable, not deductible). However, the original portion under the original order may still follow the pre-2019 rules (taxable and deductible).

The IRS guidance on this is limited, and different tax professionals interpret it differently. If you modified your order after 2018, you should document the modification in writing and consider consulting a tax professional before filing your return. Some modifications are treated as terminations of the old order and creation of a new one; others are treated as amendments to the existing order. The distinction matters for tax purposes.

Frequently Asked Questions

Do I have to report alimony I received if I did not receive a 1099 form?

Yes, if your divorce was finalized before 2019, you must report alimony as income even if you do not receive a 1099. The payer is not required to issue a 1099 for alimony payments. You are responsible for reporting it based on the amount you actually received. Keep your own records of deposits and payments.

What if the payer and I disagree on the amount of alimony paid?

The IRS will expect both of you to report the same amount. If there is a discrepancy, the IRS may contact one or both of you. If you genuinely disagree on the amount, you should resolve it with your ex-spouse or through your attorney before filing. If you cannot agree, document your position and be prepared to explain it if audited.

Does California state tax treat alimony differently than federal tax?

No. California follows federal tax law for alimony. If alimony is taxable under federal rules, it is taxable under California rules. If it is not taxable federally, it is not taxable in California. You report alimony on your federal return, and California taxes it the same way.

If I pay alimony, can I deduct it even if the recipient does not report it as income?

If your divorce was before 2019, you can claim the deduction on your return, but the IRS will cross-check it against what the recipient reported. If the recipient does not report the income, the IRS will likely contact one or both of you. You cannot deduct alimony if the recipient fails to report it — that is their tax problem, not yours, but it may trigger an audit for both of you.

What if my divorce was finalized before 2019 but I just started paying alimony now?

The tax treatment is based on when the divorce was finalized, not when payments began. If the divorce was before 2019, alimony is taxable and deductible, even if you are paying it years later. Report it on your return for the year you actually made the payment.
