How California taxes retirement income
California uses a graduated state income-tax system that runs from 1% up to 13.3% on taxable income. Federal pension income — including FERS and CSRS annuities — and Thrift Savings Plan (TSP) withdrawals are taxed as ordinary income. There is no state-level carve-out, which puts California in the same bucket as states like Idaho and Nebraska that tax federal pensions in full. The states that exempt federal pensions (Hawaii, Illinois, Mississippi, Pennsylvania, and several others) are noticeably better for federal retirees.
Military retirement pay has historically been taxed in full as well. California recently passed legislation introducing limited exemptions for some military retirees, but the rules are complex, vary by income, and may change again. Verify current treatment with the California Franchise Tax Board or a California-licensed tax professional. Social Security retirement benefits are not taxed by California — they pass through state taxation entirely (federal taxation may still apply depending on your provisional income).
What you'll actually pay (worked examples)
Example 1 — FERS retiree, $90k pension + $30k Social Security
An FERS retiree drawing a $90,000 annual pension and $30,000 in Social Security (single filer) reports the $90,000 pension as California taxable income. Social Security is excluded. After the standard deduction, taxable income is roughly $84,500. Applying California's graduated brackets (1% to 9.3% up to about $375k of taxable income), state tax is approximately $4,000 – $5,000 per year. Over a 25-year retirement, that's $100,000 to $125,000 in cumulative state tax — money a retiree in Nevada or Washington wouldn't pay at all.
Example 2 — Military retiree, $50k retired pay + $20k VA disability
A military retiree drawing $50,000 in retired pay and $20,000 in VA disability compensation (married filing jointly, no other income). VA disability is federally tax-free and not California taxable income. Whether the $50k of military retirement is taxable depends on California's current military-retirement rules, which are in flux. If fully taxable, California state tax would be roughly $1,200 – $1,800 per year. Over a 30-year retirement, that compounds to roughly $45,000 – $65,000. If a partial exemption applies, the cost is lower.
These figures are estimates using California 2025 brackets and the standard deduction. Your actual tax depends on filing status, total income, deductions, credits, and the most current state law. Verify with a CA-licensed tax professional before making relocation or retirement decisions.
Compared to neighboring states
- Nevada: No state income tax. A retiree moving from California to Nevada keeps every dollar of their pension untouched at the state level.
- Washington: No personal income tax. (Note: there is a state-level capital gains tax above $250k, but it does not apply to pension or wage income.)
- Arizona: Taxes pension income, but at a flat rate around 2.5% — meaningfully lower than California's 6-9% bracket for typical retirees.
- Oregon: Taxes federal pensions, but exempts the portion attributable to federal service before October 1, 1991. Top bracket is 9.9%. Roughly comparable to California for most retirees.
Domicile and residency considerations
California aggressively pursues former residents who continue to source income from the state. If you're considering relocating to a tax-free state, it's not enough to buy a house elsewhere — California uses a "facts and circumstances" test that looks at where you spend the most time, where your driver's license is, where you bank, where you vote, where your doctors and dentists are, and where your closest family lives. Pension income paid to a former California resident who has properly established domicile elsewhere is generally not subject to California state tax under federal law (4 USC § 114), which prevents source-state taxation of pension income paid to non-residents.
For active-duty military retirees and federal employees still working in California, the rules are different. Plan a relocation carefully and ideally consult a tax professional with California experience before the year you intend to retire.

Common questions
Does California tax federal pensions?
Yes. California fully taxes Federal Employee Retirement System (FERS) and Civil Service Retirement System (CSRS) pension income at ordinary state income-tax rates. Unlike many states (Hawaii, Illinois, Mississippi, Pennsylvania, and others), California offers no carve-out or exemption for federal pension income.
Does California tax military retirement pay?
California historically taxed military retirement pay in full. Recent legislative changes have introduced limited exemptions for some retirees, but California is still one of the least military-friendly states for retirement-pay taxation. Verify the current rules with the California Franchise Tax Board (FTB) or a CA-licensed tax professional before relying on any specific exemption.
Does California tax Social Security?
No. California is one of the majority of states that fully exempt Social Security retirement benefits from state income tax. This applies to your monthly SS retirement check including any cost-of-living adjustments. Federal taxation of SS still applies depending on your provisional income.
What is the effective state-tax rate for a typical federal retiree in California?
Most federal retirees in California fall into the 6% to 9.3% marginal bracket on their pension and TSP withdrawals, with an effective rate between 4% and 7% after accounting for the standard deduction and the SS exemption. The headline 13.3% top rate only applies to taxable income over roughly $1 million — not relevant for typical retirees.
How does California compare to neighboring states for retirement?
Nevada has no state income tax at all. Washington state has no income tax (but does tax some capital gains over $250k). Arizona taxes pensions but caps the top rate around 2.5%. Oregon taxes federal pensions but exempts the portion attributable to pre-October 1991 federal service. California is the highest-tax option among Western states for retirees with pension income.
