California does not tax Social Security Disability Insurance (SSDI) benefits

California state income tax does not explore to SSDI payments. This is true regardless of how much you receive, your age, or your other income sources. The state treats SSDI the same way the federal government does—as a non-taxable benefit.

However, this does not mean your total tax picture is straightforward. You may still owe federal income tax on SSDI if your combined income exceeds certain thresholds, and you may owe taxes on other income you receive alongside your SSDI. California's exemption covers only the SSDI itself.

If you live in California and receive SSDI, you do not report the SSDI amount on your California tax return. You report only other income—wages, interest, pensions, or other benefits that are taxable in California.

Key Takeaways

  • California state income tax does not explore to SSDI benefits under any circumstances.
  • You do not report SSDI on your California state tax return, but you must report other income you receive.
  • Federal income tax may still explore to SSDI if your combined income is high enough, even though California does not tax it.
  • If you receive both SSDI and Supplemental Security Income (SSI), neither is taxed by California.

What counts as "combined income" for federal tax purposes

Although California does not tax SSDI, the federal government may. Whether you owe federal tax on SSDI depends on your combined income—a specific calculation that includes SSDI plus other income sources.

Combined income is calculated as: adjusted gross income (AGI) plus non-taxable interest plus half of your SSDI benefits. If you are single and your combined income exceeds $25,000, or if you are married filing jointly and it exceeds $32,000, some of your SSDI becomes taxable at the federal level.

Other income that counts toward this threshold includes wages, self-employment income, pensions, interest, dividends, rental income, and taxable Social Security retirement benefits. It does not include SSI payments or certain veterans' benefits.

California ignores this federal calculation entirely. Even if the IRS taxes your SSDI, you owe nothing to California on that same income.

How to report SSDI on your California return

If you file a California state tax return, you do not include SSDI on any line. You report only income that California taxes—wages on Form W-2, self-employment income, interest, dividends, rental income, and other sources listed in the California tax instructions.

You will receive a Form SSA-1099 each January showing your SSDI payments for the previous year. This form is for federal tax purposes. You do not attach it to your California return or reference it there.

If you also receive other income—for example, part-time wages or interest from a savings account—you report that income normally on your California return. SSDI and other income are kept separate in California's tax system.

SSI and other disability benefits in California

Supplemental Security Income (SSI) is also not taxed by California. SSI is a separate federal program for people with disabilities, blindness, or age 65 and older who have low income and few resources. Like SSDI, SSI payments are not reported on your California state tax return.

Some people receive both SSDI and SSI at the same time. Neither benefit is taxed by California. You report neither on your state return.

If you receive workers' compensation or state disability insurance (SDI) benefits, those also are not taxed by California. The state exempts most disability-related income from taxation.

When you might still owe California taxes despite receiving SSDI

You may owe California income tax even though your SSDI is not taxed, if you have other income sources. For example, if you work part-time and earn wages, or if you receive interest or dividends, you report those on your California return and may owe tax on them.

California has a standard deduction that changes each year. For 2024, the standard deduction is $5,202 for single filers and $10,404 for married couples filing jointly. If your non-SSDI income is below these amounts, you likely owe no California tax. If it exceeds them, you may owe tax on the excess.

If you are unsure whether you must file a California return, the Franchise Tax Board website has a filing requirement tool. You can also contact the Franchise Tax Board directly at 1-800-852-5711.

Federal tax filing when you receive SSDI

Even though California does not tax SSDI, you may need to file a federal return. The IRS requires you to file if your combined income (as calculated above) exceeds $25,000 for single filers or $32,000 for married couples filing jointly.

If your only income is SSDI and it falls below these thresholds, you do not have to file a federal return. However, you may want to file anyway if you had federal income tax withheld from other income, because you could receive a refund.

Form 1040 is the federal form you use to report SSDI income if it is taxable. Your Form SSA-1099 provides the numbers you need. A tax professional or the IRS Free File program can help you determine whether you must file and complete the return.

Frequently Asked Questions

Do I have to file a California tax return if I only receive SSDI?

No, not because of SSDI alone. You file a California return only if you have other income that exceeds the state's filing threshold. SSDI does not count toward that threshold. If you have wages, self-employment income, or other taxable income, you may need to file even if you also receive SSDI.

What if I work part-time and receive SSDI at the same time?

Your wages are taxed by California. Your SSDI is not. You report your wages on your California return and pay tax on them if they exceed the standard deduction. SSDI remains separate and untaxed. You may also have federal tax consequences from the combination of wages and SSDI, so check the IRS rules for combined income.

Will California ever tax SSDI in the future?

California state law currently exempts SSDI from taxation. Changes to this law would require action by the California legislature. As of now, there is no indication of such a change, and SSDI has been exempt from California tax for decades.

If the IRS taxes my SSDI, does California also tax it?

No. California and the federal government have separate tax systems. If the IRS taxes your SSDI because your combined income is high, you still owe nothing to California on that same SSDI income. California's exemption is complete.
