California does not tax Social Security benefits, even if your federal return does

If you receive Social Security in California, the state will not tax those payments. California is one of a small group of states that exempts Social Security income entirely from state income tax. This is true regardless of how much you earn from other sources, whether you file a federal return that includes Social Security income, or what your total household income is.

The federal government may tax your Social Security benefits depending on your combined income—but California will not. This distinction matters because your federal tax bill and your California tax bill are calculated separately, using different rules.

Key Takeaways

  • California does not tax Social Security benefits at the state level, even if the federal government taxes them on your federal return.
  • Your combined income (wages, interest, half of Social Security benefits) determines whether the federal government taxes your benefits, not California.
  • You still file a California state return if you owe federal income tax or meet other filing requirements, but Social Security income is excluded from California taxable income.
  • If you moved to California from another state, your Social Security was likely already exempt in your previous state as well.

Why California exempts Social Security from state tax

California has excluded Social Security benefits from state income tax since 1992. The law treats Social Security as a form of insurance benefit rather than earned income, similar to how workers' compensation and certain disability payments are handled.

This exemption applies to all Social Security recipients living in California, regardless of age or income level. You do not need to request the exemption or file a special form—it is automatic. When you file your California state return, Social Security income straightforward does not appear in the calculation of what you owe.

How federal taxation of Social Security works differently

The federal government uses a different test. If your combined income exceeds certain thresholds, the IRS taxes up to 85 percent of your Social Security benefits. Combined income means your adjusted gross income plus non-taxable interest plus half of your Social Security benefits.

For 2024, if you file as single and your combined income exceeds $25,000, you may owe federal tax on some of your benefits. If you file as married filing jointly, the threshold is $32,000. These thresholds have not changed since 1984, so more beneficiaries cross them each year as wages and investment income rise.

California does not use this combined-income test. The state straightforward excludes all Social Security from taxable income, period. So you could have $100,000 in combined income and owe federal tax on your benefits while owing nothing to California.

What to report on your California state return

When you file your California Form 540 (the state income tax return), you report your federal adjusted gross income as a starting point. However, California then subtracts out the Social Security income that was included in that federal number. The result is your California taxable income, which is typically lower than your federal taxable income.

You do not need to file a California return at all if your only income is Social Security, even if you file a federal return. However, if you have wages, self-employment income, interest, dividends, or other income sources, you file normally and straightforward benefit from the Social Security exemption automatically.

Keep your Social Security statement (Form SSA-1099) with your tax records. This form shows how much you received during the year and is what you use to calculate both your federal and California tax positions.

Other states that do not tax Social Security

Thirteen states do not tax Social Security benefits: Alabama, Alaska, Florida, Georgia, Illinois, Iowa, Kentucky, Louisiana, Mississippi, Nevada, Pennsylvania, South Carolina, Tennessee, and Texas. If you moved to California from one of these states, you were already exempt. If you moved from a state that does tax Social Security (such as Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, or Vermont), you now benefit from California's exemption.

The rules vary by state. Some states exempt Social Security but tax other retirement income like pensions or 401(k) withdrawals. California exempts Social Security but does tax pensions, 401(k) distributions, and IRA withdrawals at the state level.

Retirement income that California does tax

While Social Security is exempt, California taxes most other retirement income. If you receive a pension from a government or private employer, California includes that in your taxable income. The same applies to 401(k) withdrawals, traditional IRA distributions, and annuity payments.

Military pensions receive a partial exemption: California excludes up to $20,000 per year of military retirement pay from state income tax. Federal employee pensions do not receive this exemption in California.

Long-term capital gains, interest, and dividends are all taxed by California at the state level. So if you have a diversified retirement income mix—Social Security, a pension, and investment income—only the Social Security portion escapes California tax.

Frequently Asked Questions

If I move out of California, will I still be exempt from California tax on my Social Security?

No. You owe California income tax only on income earned while you were a California resident. Once you move, you file a part-year return for the months you lived in California and a resident return for your new state. Your new state's rules on Social Security explore to benefits received after you move.

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

Not unless you have other income that triggers a filing requirement. Social Security alone does not require you to file a state return. However, if you have wages, self-employment income, or other sources, you file normally and benefit from the Social Security exemption automatically.

What if the federal government taxes my Social Security—do I owe California anything?

No. Federal taxation and California taxation are separate. You can owe federal tax on your benefits and owe nothing to California. The state exemption is complete and does not depend on your federal tax situation.

Does California tax Supplemental Security Income (SSI)?

No. California also exempts SSI from state income tax. SSI is a needs-based program for low-income seniors, blind individuals, and disabled people, and it is treated the same way as Social Security for California tax purposes.

If I worked in California but now live elsewhere, do I still get the exemption?

The exemption applies based on where you live when you receive the benefits, not where you worked. If you live in California, your Social Security is exempt. If you move to another state, that state's rules explore to your benefits going forward.
