California does not tax Social Security benefits

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

The federal government may tax your Social Security benefits depending on your combined income, but California itself does not. This distinction matters because it means you keep more of your Social Security payment in California than you would in many other states.

Key Takeaways

  • California exempts all Social Security benefits from state income tax, with no income limit or exception.
  • Federal tax on Social Security depends on your combined income (Social Security plus other earnings), not on California's rules.
  • If you have other income besides Social Security, you may owe California tax on that income, but not on the Social Security portion.
  • You do not need to report Social Security as income on your California tax return, though you may still need to file for other reasons.

What counts as combined income for federal tax purposes

The federal government uses a formula called "combined income" to decide whether your Social Security is taxable. Combined income means your adjusted gross income plus nontaxable interest plus half of your Social Security benefits. If this total exceeds certain thresholds, part of your benefit becomes taxable at the federal level.

For 2024, if you file as single and your combined income exceeds $25,000, you may owe federal tax on up to 50 percent of your benefits. If it exceeds $34,000, you may owe federal tax on up to 85 percent of your benefits. For married couples filing jointly, the thresholds are $32,000 and $44,000. These thresholds have not changed since 1984, so they affect more people each year as incomes rise.

California does not use this formula. The state simply does not tax Social Security at all, regardless of your combined income or any other factor.

Other income you receive alongside Social Security

If you have income from sources other than Social Security—such as wages, self-employment, pensions, interest, dividends, or rental income—California will tax that income according to its state tax brackets. Social Security itself remains untaxed, but your other earnings do not.

For example, if you receive $20,000 in Social Security and $15,000 in pension income, California taxes only the $15,000 pension portion. You will still owe federal tax on part of your Social Security if your combined income crosses the federal threshold, but California's portion of your bill comes only from the pension.

Whether you need to file a California tax return

You do not file Social Security on your California return because it is not taxable income in the state. However, you may still need to file a California return if you have other income that exceeds the filing threshold for your age and filing status.

For 2024, the California filing threshold for a single person age 65 or older is $20,824 in gross income. For a married couple filing jointly where at least one spouse is 65 or older, it is $41,648. These thresholds apply only to income that California taxes—so again, Social Security does not count toward them.

If your only income is Social Security, you do not need to file a California return. If you have other income, check whether it exceeds your threshold. You may still want to file even if you are not required to, because you might be owed a refund or a tax credit.

Federal filing requirements when you receive Social Security

Federal tax rules are separate from California's. You may need to file a federal return even if you do not file in California. The federal threshold for Social Security recipients depends on your combined income, not just your Social Security amount.

For 2024, if you are single and your combined income is $14,600 or more, you must file a federal return. If you are married filing jointly and your combined income is $29,200 or more (or $23,200 if only one spouse has Social Security), you must file. These thresholds are higher than California's because they account for the federal standard deduction.

The IRS provides a worksheet to calculate whether your Social Security is taxable at the federal level. You can find this on the IRS website or ask a tax preparer to walk you through it.

States that do tax Social Security, and why California differs

Thirteen states tax Social Security benefits to some degree: Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, Vermont, and West Virginia. Most of these states tax only a portion of benefits or only for higher-income recipients. A few tax all benefits the same way they tax other income.

California chose not to tax Social Security at all. This is a state policy decision, not a federal rule. Some states exempt Social Security entirely; others tax it partially or fully. If you move to another state, your Social Security tax situation may change, so it is worth checking the rules of your new state before you relocate.

Frequently Asked Questions

Do I report Social Security on my California tax return?

No. California does not require you to report Social Security income on your state return because it is not taxable in the state. You only report other income sources, such as wages, pensions, or interest.

Will I owe federal tax on my Social Security even though California does not tax it?

Possibly. Federal tax on Social Security depends on your combined income, which is a separate calculation from California's rules. You may owe federal tax while owing nothing to California, or vice versa. Check your combined income against the federal thresholds to know for sure.

What if I move to another state—will my Social Security still be tax-free?

It depends on which state you move to. Thirteen states tax Social Security to some degree. If you move to one of them, your Social Security may become taxable under that state's rules. Check the tax laws of your new state before you relocate.

Do I need to file a California return if Social Security is my only income?

No, you do not need to file a California return if Social Security is your only income. However, you may still need to file a federal return depending on your combined income and the federal thresholds for your filing status.

If I have a pension and Social Security, how much of each is taxed in California?

California taxes your pension according to its tax brackets but does not tax your Social Security at all. Only the pension portion counts toward your California tax bill. Your federal tax bill may include part of your Social Security if your combined income exceeds the federal threshold.
