Does California Tax Social Security Benefits in 2026?
No, California does not tax Social Security benefits. Whether you receive retirement, disability, or survivor benefits, the state leaves them out of your California taxable income, even though the federal government may still tax part of the same benefits.
Key takeaways
- California does not tax Social Security benefits, whatever your income or filing status.
- Federal tax is separate: up to 85% of benefits can be federally taxable.
- Combined income is AGI plus tax-exempt interest plus half your benefits.
- California still taxes pensions and traditional 401(k) and IRA withdrawals.
- Subtract any federally taxable Social Security on Schedule CA (540) for California.
The short answer: no California tax on Social Security
The state excludes United States Social Security benefits from taxable income, and the same exclusion covers equivalent Tier 1 railroad retirement benefits. The California Franchise Tax Board states this in its Schedule CA instructions: the taxable Social Security amount is entered as a subtraction, so it does not carry into your California tax calculation.
The exemption has no income cap and no phase-out. A retiree living only on Social Security and a retiree with a large pension are treated the same way on this point: California taxes neither of their benefits. Other income can still be taxed, but it does not turn Social Security into California-taxable income.
Why you can still owe federal tax on the same benefits
Federal and state tax are two separate calculations. The Social Security Administration explains that you may have to pay federal tax on up to 85% of your benefits if your combined income exceeds $25,000 as an individual filer or $32,000 on a joint return. Combined income is adjusted gross income plus tax-exempt interest plus one-half of your annual Social Security benefits.
Tax-exempt interest still counts toward that test, while only half your benefits enter it. The percentages below are the share of benefits counted as taxable income, not your tax rate. Any taxable portion is then taxed at your ordinary federal rate.
| Filing status | Combined income | Share federally taxable | California tax |
|---|---|---|---|
| Single, head of household, survivor | Up to $25,000 | 0% | None |
| Single, head of household, survivor | $25,000 to $34,000 | Up to 50% | None |
| Single, head of household, survivor | Over $34,000 | Up to 85% | None |
| Married filing jointly | Up to $32,000 | 0% | None |
| Married filing jointly | $32,000 to $44,000 | Up to 50% | None |
| Married filing jointly | Over $44,000 | Up to 85% | None |
These thresholds have not been adjusted for inflation like benefit amounts have, so a modest pension can push a retiree over a line that once affected far fewer people. Couples filing separately who lived together face a $0 federal base amount, so use the full worksheet in that case.
Worked example: the same benefits, two different tax bills
The example below is illustrative only, using round numbers to show the federal phase-in, with no tax-exempt interest in either case. It is not a filing calculation for any real return.
Example A, single filer. You receive $24,000 a year in Social Security and have $20,000 of other adjusted gross income. Combined income is $20,000 plus half of $24,000, or $32,000. That sits in the $25,000 to $34,000 band, so the federal taxable portion is phased in: half of the $7,000 excess over $25,000, or $3,500. California tax on the Social Security itself is $0.
Example B, married couple filing jointly. The couple receives $36,000 a year in Social Security and has $40,000 of other adjusted gross income. Combined income is $40,000 plus half of $36,000, or $58,000, above the $44,000 second threshold. The federal result is $17,900 of taxable Social Security: $6,000 from the first tier, half of the $12,000 band between $32,000 and $44,000, plus 85% of the $14,000 excess over $44,000, or $11,900. That is below the 85% cap of $30,600. California tax on the Social Security itself is $0.
Example B has far more federally taxable Social Security, yet both pay no California tax on their benefits.
What California does tax in retirement
The exemption is narrow, and that is where most California retirement tax bills come from. California generally taxes pension payments, traditional 401(k) distributions, and traditional IRA withdrawals as ordinary income, at graduated state rates. Neither has a general state exemption; the question is how much taxable income each produces in a year.
Qualified Roth IRA and Roth 401(k) withdrawals are the notable exception, generally tax-free at both levels when federal conditions are met. Part-time earnings, investment, rental, and capital gains income are taxed on their own terms, with no special California long-term capital gains rate.
How to handle it on your returns
Start with your federal return, because California starts from federal adjusted gross income. If part of your Social Security was federally taxable, it is already inside that figure. For California, subtract it on Schedule CA (540), line 6, as the Franchise Tax Board instructs. Residents use Schedule CA (540); nonresidents and part-year residents use Schedule CA (540NR) and make the same adjustment. Tax software usually does this, but check the subtraction is present before filing.
Withholding aimed at the federal bill does not create a California bill on Social Security, and a low California bill does not mean the federal bill is also low. Keep both returns together: the federal figure shows what was counted federally, and the California subtraction shows what was removed for state purposes. California also taxes residents on worldwide income, so a new resident is taxed by California on pensions and withdrawals wherever earned, while Social Security remains exempt. By contrast, states with no state income tax charge no state tax on pensions or withdrawals either. For the pension side, see our guide to pension versus 401(k) plans.
