California does not tax Social Security benefits

California is one of the states that does not impose state income tax on Social Security payments. If you receive Social Security retirement, survivor, or disability benefits, you will not owe California state income tax on those payments, regardless of how much you receive or what other income you have.

This is different from federal income tax. The federal government may tax your Social Security benefits depending on your total income, but California will not. The state's tax code specifically excludes Social Security from taxable income.

This protection applies to all types of Social Security payments: retirement benefits, spousal benefits, survivor benefits for family members, and Supplemental Security Income (SSI). It also applies whether you receive benefits directly or as a representative payee managing benefits for someone else.

Key Takeaways

  • California does not tax Social Security benefits at the state level, so you will not owe California income tax on these payments.
  • The federal government may still tax your Social Security depending on your total income, even though California does not.
  • This protection covers all types of Social Security: retirement, spousal, survivor, and SSI benefits.
  • Other retirement income you receive — pensions, 401(k) withdrawals, investment income — is still subject to California state tax.
  • If you file a California state tax return, you do not report Social Security as income on that return.

How federal taxation of Social Security works

While California does not tax Social Security, the federal government may. Whether your benefits are taxed federally depends on your "combined income," which is calculated as your adjusted gross income plus nontaxable interest plus half of your Social Security benefits.

If your combined income exceeds certain thresholds, up to 50 percent or 85 percent of your Social Security benefits may be subject to federal income tax. For 2024, the thresholds are $25,000 for single filers and $32,000 for married couples filing jointly. These thresholds have not changed since 1984, so more people are affected each year as incomes rise.

You can estimate your federal tax liability using the Social Security Administration's online calculator, or you can ask a tax preparer to run the numbers. The IRS Form 1040 includes worksheets to calculate taxable Social Security if you need to file federally.

What income counts toward the federal threshold

Combined income includes wages, self-employment income, interest, dividends, capital gains, rental income, and distributions from retirement accounts. It also includes half of your Social Security benefits themselves, which is why even modest other income can push you over the threshold.

Some types of income do not count: California state tax refunds, life insurance proceeds, and certain municipal bond interest. If you have very little income besides Social Security, you may not owe federal tax on your benefits even if you file a return.

Pensions and 401(k) withdrawals count as income for this calculation. If you are retired and drawing from multiple sources, your tax preparer should review all of them together to see whether your Social Security will be taxed federally.

Filing taxes in California when you receive Social Security

You may still need to file a California state tax return even though Social Security is not taxed. California requires you to file if your income from other sources exceeds the filing threshold for your age and filing status. For 2024, the threshold is $20,824 for single filers age 65 and older.

When you file, you do not report Social Security on your California return. You report only your other income: wages, pensions, retirement account withdrawals, investment income, and any other taxable sources. The state tax form will not have a line for Social Security income.

If you owe federal income tax on your Social Security, you will report that on your federal return (Form 1040), not on your California return. The two tax systems are separate, and California's lack of taxation on Social Security means you will have a lower state tax bill than you would in a state that does tax these benefits.

Other California retirement income that is taxed

While Social Security escapes California taxation, other retirement income does not. Distributions from traditional IRAs, 401(k)s, and 403(b) plans are fully taxable as California income. Pension payments from public or private employers are also taxable in California.

Roth IRA distributions are not taxed if the account has been open for five years and you are at least 59½. However, if you withdraw earnings before meeting these conditions, those earnings are taxable in California.

If you have substantial retirement income from pensions or retirement accounts, you may owe significant California state tax even though your Social Security is protected. A tax preparer can help you understand your total tax picture and explore whether you should adjust withholding or make estimated tax payments.

Planning around California's tax treatment

Because California does not tax Social Security but does tax other retirement income, some people structure their retirement to maximize Social Security relative to other sources. This is not always possible — your Social Security amount is set by your earnings history and the age you claim — but it is worth understanding as part of your overall picture.

If you are still working and receiving Social Security, California taxes your wages normally. The state does not reduce your tax burden because you are also receiving benefits. Your total tax liability depends on all your income combined.

If you are considering moving to California or leaving the state, Social Security taxation is one factor to weigh, but not the only one. Some states tax Social Security and some do not; some have no state income tax at all. A tax professional can compare your situation across states if you are making a move.

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 and it is below the filing threshold, you do not have to file. However, if you have other income — wages, pensions, investment income — you may need to file even though your Social Security itself is not taxed. Check the current filing threshold for your age and status on the Franchise Tax Board website.

Will I owe California taxes if my Social Security is taxed federally?

No. Federal taxation and California state taxation are separate. You can owe federal tax on your Social Security and still owe zero California state tax on it. Your federal tax bill depends on your combined income; your California bill does not include Social Security at all.

Are SSI (Supplemental Security Income) payments taxed in California?

No. SSI is not taxed by California, just like Social Security retirement and disability benefits. However, SSI is also not taxed federally. If you receive SSI, you generally will not owe income tax to either the state or federal government on those payments.

If I move out of California, will my Social Security be taxed?

It depends on which state you move to. Some states tax Social Security and some do not. A few states have no income tax at all. If you are considering a move, research that state's tax treatment of Social Security before you go, as it can affect your retirement income significantly.

Does California tax my spouse's Social Security if we file jointly?

No. California does not tax Social Security for anyone, whether you are filing alone or jointly. Your spouse's benefits are also excluded from California taxable income, though they may be subject to federal tax depending on your combined household income.
