California does not tax Social Security benefits

California state income tax does not apply to Social Security payments. This is true whether you receive retirement benefits, survivor benefits, or disability benefits through Social Security. The state treats Social Security income as exempt from taxation, separate from how the federal government handles it.

However, you may still owe federal income tax on your Social Security benefits depending on your total income. The federal threshold is based on your "combined income" — a calculation that includes half of your Social Security plus all other income sources. If your combined income exceeds $25,000 (single filer) or $32,000 (married filing jointly), you may owe federal tax on up to 85 percent of your benefits.

California's exemption applies only to state taxes. It does not change what you owe to the IRS, and it does not change how Social Security interacts with other California benefits like Supplemental Security Income (SSI) or In-Home Supportive Services (IHSS).

Key Takeaways

  • California state income tax does not apply to any Social Security benefits you receive, whether from retirement, disability, or survivor programs.
  • Federal income tax may still apply to your Social Security benefits if your combined income (half your benefits plus other income) exceeds $25,000 for single filers or $32,000 for married filers.
  • Social Security income still counts as income when determining your may be able to access for other California assistance programs like SSI or IHSS.
  • You do not need to report Social Security income on your California state tax return, but you may need to report it on your federal return.

How federal taxation of Social Security works

The federal government uses a formula to determine whether your Social Security is taxable. Start by adding half of your annual Social Security benefit to all your other income — wages, pensions, interest, rental income, and other sources. This total is your "combined income."

If your combined income is below $25,000 (single) or $32,000 (married filing jointly), you owe no federal tax on your benefits. If it exceeds those thresholds, up to 50 percent of your benefits may be taxable. If your combined income exceeds $34,000 (single) or $44,000 (married), up to 85 percent of your benefits may be taxable.

The IRS sends you a Form SSA-1099 each January showing how much you received in benefits during the previous year. You use this figure to calculate your federal tax liability. Many people with Social Security as their only income owe no federal tax at all.

Social Security income and other California programs

Even though California does not tax Social Security, the state counts it as income when you apply for other assistance. SSI, IHSS, CalFresh (food assistance), and Medi-Cal all treat Social Security as countable income. Receiving Social Security can reduce your benefit amount or make you ineligible for these programs.

SSI has a monthly income limit of $943 for individuals and $1,415 for couples (2024 figures; these change yearly). If your Social Security benefit exceeds these amounts, you will not receive SSI. IHSS and CalFresh have higher income limits, but Social Security still counts toward them.

If you receive both Social Security and SSI, the SSI program will reduce your monthly payment dollar-for-dollar for every dollar of Social Security you get. This is called "deemed income." You should report all Social Security income to the Social Security Administration when you apply for SSI or when your benefits change.

What documents show your Social Security income

The Social Security Administration sends you a Form SSA-1099 each January. This form shows your total benefits for the previous calendar year. You use it to file your federal tax return and to report income to other agencies.

Your Social Security statement (available at ssa.gov) shows your current monthly benefit amount. When you apply for other California programs, you will usually need to provide either your SSA-1099, a recent benefit statement, or a letter from Social Security showing your monthly payment. Some programs accept a bank statement showing regular Social Security deposits.

If you have not received an SSA-1099 by early February, you can request one by calling Social Security at 1-800-772-1213 or by visiting your local Social Security office.

Reporting Social Security on your California tax return

You do not report Social Security income on your California state tax return. California Form 540 (the state income tax form) does not have a line for Social Security benefits because the state does not tax them. If you file a California return, you simply omit Social Security from your income calculation.

You may still need to file a California return even if you owe no state tax. This is true if you have other income sources — wages, pensions, or self-employment income — that exceed California's filing threshold. The threshold varies by age and filing status; for 2024, it is $20,824 for single filers under 65.

If you file a federal return (which you may need to do even if you owe no federal tax), you will report your Social Security on Form 1040. Your tax software or a tax preparer can walk you through this calculation.

What happens if you work while receiving Social Security

If you are under your full retirement age and you earn wages from work, Social Security will reduce your benefits. For 2024, Social Security deducts $1 in benefits for every $2 you earn above $23,400 per year. The year you reach full retirement age, the limit is higher and applies only to earnings before the month you reach full retirement age.

Once you reach full retirement age, you can earn as much as you want without any reduction to your benefits. California does not tax your Social Security, but it does tax your wages. If your wages push you over California's filing threshold, you will owe state income tax on those wages.

The earnings limit applies only to work income, not to other sources like pensions, investments, or rental income. Social Security counts only wages and self-employment income toward the limit.

Frequently Asked Questions

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

No. If Social Security is your only income source, you do not need to file a California state return. However, you may want to file a federal return to claim the Earned Income Tax Credit or other federal credits, even if you owe no tax.

Will getting Social Security affect my CalFresh or Medi-Cal benefits?

Yes. Social Security counts as income for both programs. Your benefit amount may be reduced, or you may become ineligible, depending on how much you receive and your other income. Contact your county social services office to report your Social Security income and see how it affects your benefits.

What if I moved to California from another state — do I owe back taxes on Social Security?

No. California does not tax Social Security for any year, regardless of when you moved to the state or where you lived previously. If another state taxed your Social Security before you moved, that state's rules applied then, but California will not tax it going forward.

Can I exclude Social Security from my income when applying for housing assistance?

It depends on the program. Some housing programs count Social Security as income; others do not. Contact the program directly — your local housing authority, a nonprofit housing organization, or the landlord's assistance program — to ask whether Social Security is counted. Many programs have different rules.

Do I need to report Social Security to the IRS if I do not file a federal tax return?

Not necessarily. If your combined income is below the federal threshold ($25,000 single, $32,000 married), you owe no federal tax and do not need to file. However, if you have other income sources or if you want to claim credits, filing may benefit you even if you owe no tax.
