California does not tax Social Security benefits

California state income tax does not apply to Social Security income, whether you receive retirement, survivor, or disability benefits. This is true regardless of your total income or filing status. If Social Security is your only income source, you will owe no California state tax on it.

The federal government also does not tax Social Security benefits for most people. However, the federal rules are more complex: if you have other income above certain thresholds, up to 85 percent of your benefits may become taxable at the federal level. California has no such rule. Your state tax liability depends only on non-Social Security income.

This distinction matters because you may owe federal tax while owing nothing to California, or vice versa. A tax professional or the IRS can help you determine your federal obligation, but California's position is straightforward: Social Security income is not taxed by the state.

Key Takeaways

  • California does not tax Social Security retirement, survivor, or disability benefits under any circumstances.
  • You may still owe federal income tax on Social Security if your other income exceeds certain thresholds, but this does not affect your California state tax.
  • If Social Security is your only income, you will owe no California state income tax.
  • Other income you receive—such as wages, pensions, or interest—is still subject to California tax, even if you also receive Social Security.
  • You should file a California tax return if you owe federal tax, even if you owe nothing to the state.

What income does California tax if you receive Social Security

California taxes all income sources except Social Security. If you receive wages, a pension, interest, dividends, rental income, or self-employment income, those are all subject to California state tax. The presence of Social Security income does not shield these other sources from taxation.

Your California tax rate depends on your total non-Social Security income. California uses a progressive tax system with rates ranging from 1 percent to 13.3 percent depending on your income bracket. You can find your bracket and calculate your estimated tax using the California Franchise Tax Board website or a tax calculator.

If you are unsure whether a specific income source is taxable in California, the Franchise Tax Board publishes a guide to taxable and nontaxable income. You can also contact them directly by phone or through their website.

Filing requirements when you receive Social Security

You must file a California tax return if your non-Social Security income exceeds the filing threshold for your age and filing status. The threshold varies by year and by whether you are single, married, or head of household. For 2024, a single person age 65 or older must file if their non-Social Security income exceeds approximately $20,000; a single person under 65 must file if non-Social Security income exceeds approximately $15,000. These amounts change annually.

Even if you owe no California tax, you may need to file to claim the California Earned Income Tax Credit or other refundable credits. You should also file if you had federal tax withheld from any income source, because you may receive a refund.

The Franchise Tax Board publishes updated filing thresholds each year on its website. You can also call them to confirm whether you must file based on your specific situation.

Federal taxation of Social Security is separate from California

The federal government taxes Social Security benefits differently than California does. If you have income from sources other than Social Security, the IRS may tax up to 85 percent of your benefits. This happens when your "combined income"—which includes half your Social Security benefits plus all other income—exceeds $25,000 for single filers or $32,000 for married couples filing jointly.

California does not use this federal formula. Even if the IRS taxes your Social Security, California will not. You may owe federal tax while owing nothing to the state, or you may owe state tax on other income while owing nothing to the federal government on your Social Security.

The IRS provides a worksheet to calculate whether your Social Security is taxable at the federal level. You can also contact the IRS directly or work with a tax professional to determine your federal obligation.

Reporting Social Security on your California return

You do not report Social Security income on your California tax return because it is not taxable in California. However, you must report all other income sources: wages, self-employment income, pensions, interest, dividends, and rental income all go on your return.

If you file a federal return, you will report your Social Security income there (even though most of it will not be taxed). Your California return is separate and does not require Social Security to be listed.

When you file, use Form 540 (California Resident Income Tax Return) or Form 540-NR (Nonresident or Part-Year Resident Income Tax Return) depending on your residency status. Both forms ask for income from various sources, but Social Security is not among them.

Special situations: Supplemental Security Income and other programs

Supplemental Security Income (SSI) is different from Social Security retirement or disability benefits. SSI is a needs-based program for people with low income and limited resources. California does not tax SSI payments, and neither does the federal government. If you receive SSI, you will not owe tax on those payments in California or federally.

If you receive both Social Security and SSI, neither is taxable in California. However, you may have other income that is taxable. For example, if you work part-time and receive both Social Security and SSI, your wages are taxable in California even though your benefits are not.

Some people also receive benefits from the California Department of Social Services, such as CalFresh or CalWORKs. These are not taxable income in California or federally. Again, any wages or other income you earn separately is still taxable.

Frequently Asked Questions

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

No. If Social Security is your only income, you have no filing requirement in California because Social Security is not taxable. However, if you had any federal tax withheld or you are due a refund, you may want to file anyway to recover that money.

What if I receive Social Security and a small pension?

Your Social Security is not taxable in California, but your pension is. You must file a California return if your pension income exceeds the filing threshold for your age and filing status. The threshold for 2024 is approximately $15,000 to $20,000 depending on your age and whether you are single or married.

Will receiving Social Security affect my California tax rate on other income?

No. Your California tax rate depends only on your non-Social Security income. Social Security does not count toward your income bracket or affect your tax rate on wages, pensions, or other sources.

Can I claim Social Security income as a deduction on my California return?

No. You cannot deduct Social Security because it is not taxable income in California. Deductions apply only to taxable income sources.

If I move out of California, will I owe tax on Social Security to another state?

Most states do not tax Social Security, but a few do. If you move, check the tax laws of your new state. You can contact that state's tax authority or a tax professional to learn whether Social Security is taxable there.
