California does not tax SSDI payments, even though the federal government may

California is one of the few states that does not tax Social Security Disability Insurance (SSDI) benefits at the state level. This means if you receive SSDI in California, you will not owe state income tax on those payments, regardless of how much you receive or what other income you have.

However, the federal government may still tax your SSDI depending on your total income for the year. The fact that California skips its own tax does not change your federal tax situation. You may still need to file a federal return and potentially pay federal tax on a portion of your benefits.

This is a real advantage for California residents on SSDI, but it only covers state tax. Understanding both the state and federal picture helps you plan what you actually owe.

Key Takeaways

  • California does not tax SSDI benefits at the state level, so you owe no California state income tax on those payments.
  • The federal government may tax up to 85 percent of your SSDI if your combined income exceeds certain thresholds, even though California does not.
  • Combined income includes SSDI, wages, interest, and half of any Social Security retirement benefits you receive.
  • You may still need to file a federal tax return even if you owe no California tax, depending on your total income.
  • Supplemental Security Income (SSI) is never taxed at either the state or federal level, and SSI is different from SSDI.

Why California does not tax SSDI

California has a state law that excludes SSDI from taxable income. This is a choice the state made, not a federal requirement. Some states tax SSDI and some do not—California chose not to.

This means you fill out your California state tax return the same way whether you received $500 in SSDI that year or $50,000. The amount does not appear as taxable income on your state return. If SSDI is your only income, you typically will not owe California state tax.

Federal tax on SSDI still applies in California

Even though California does not tax SSDI, the federal government does—but only under certain conditions. The federal rule depends on your combined income, which is calculated in a specific way.

Combined income means: your SSDI amount, plus any wages you earned, plus interest and dividends, plus half of any Social Security retirement benefits you receive. If your combined income is below $25,000 (or $32,000 if you are married filing jointly), you owe no federal tax on your SSDI.

If your combined income exceeds those thresholds, you may owe federal tax on up to 50 percent or 85 percent of your SSDI, depending on how far over the threshold you go. This is a federal calculation that happens the same way in California as it does in every other state.

How to figure out if you owe federal tax on SSDI

The Social Security Administration sends you a form called SSA-1099-Soc each January. This form shows how much SSDI you received in the previous year. You use this number to calculate your combined income.

To learn about any of your SSDI is taxable at the federal level, add up: your SSDI amount (from the SSA-1099-Soc), any wages you earned, any interest or dividends, and half of any Social Security retirement benefits. If the total is under $25,000 (single) or $32,000 (married filing jointly), you owe no federal tax on SSDI.

If the total is higher, you can use the IRS worksheet in Publication 915 to calculate exactly how much of your SSDI becomes taxable. Many people find it easier to work with a tax preparer who understands SSDI, because the calculation is not straightforward.

What counts as income when calculating federal tax

The federal government counts several types of income when deciding whether your SSDI is taxable. Wages from work count. Interest from a savings account counts. Dividends from investments count. Rental income counts.

Half of any Social Security retirement benefits you receive also counts, even though those benefits themselves are not taxed in California either. This rule catches people who receive both SSDI and retirement benefits, or who receive SSDI and then later switch to retirement benefits.

Income that does not count includes: Supplemental Security Income (SSI), which is a different program entirely; gifts; loans; returns of your own money; and certain other sources. If you are unsure whether something counts, the IRS Publication 915 lists the full rules.

SSI is never taxed in California or federally

If you receive Supplemental Security Income (SSI) instead of SSDI, the tax situation is simpler: SSI is never taxed, in California or at the federal level. SSI is a needs-based program for people with low income and resources, while SSDI is an insurance program based on work history.

Some people receive both SSI and SSDI at the same time. If you do, the SSI portion is never taxed. Only the SSDI portion may be taxed federally if your combined income is high enough.

Filing a federal return even if you owe no California tax

Just because you owe no California state tax does not mean you can skip filing a federal return. The federal threshold for filing is different from California's threshold.

If your combined income (including SSDI) is above $14,600 (for a single person under 65 in 2024), you must file a federal return, even if you owe no tax. The exact threshold changes each year and depends on your age and filing status. Check the IRS website or Publication 915 for the current year's threshold.

Filing even when you owe no tax can be worth it, because you may be may have access to to refundable credits like the Earned Income Tax Credit, which can result in a refund.
