Does California Tax Pensions? Social Security, 401k & CalPERS
California taxes pension income in a way that differs from some other states.
It has a reputation as a high-tax state for retirees. That reputation is accurate to some extent.
For retirees receiving pension payments, the state’s tax treatment of those benefits can affect their overall retirement income and tax liability.
The rules vary based on factors such as residency and the type of pension received.
Are Social Security Benefits Taxed in California?
California does not tax Social Security benefits.
All Social Security included in federal adjusted gross income gets subtracted right back.
A retiree living on $30,000 of Social Security alone, with no other income, owes exactly $0 in California tax on it.
Note: This exemption also applies to Railroad Retirement Tier I benefits.
But, Tier II railroad benefits are exempt only to the extent they are treated as a Social Security equivalent. Any portion that does not qualify as a Social Security equivalent may still be subject to taxation.
California Taxation of Retirement Income Sources
Unsurprisingly, this is where California’s reputation catches up with it.
Any qualified-plan distribution, such as IRAs, 401(k)/403(b)/457 accounts, or pension annuities, is fully taxable as ordinary income to a California resident, to the extent it’s attributable to pre-tax contributions.
| Retirement Income Source | Taxable in California? | California Tax Treatment |
|---|---|---|
| Private Pensions (Corporate Pension Plans, 401(a), 403(b) Pension Plans) |
Yes | Ordinary income tax (1%–12.3%; up to 13.3% at highest incomes). |
| Public Pensions (CalPERS, CalSTRS, Federal Civil Service, Military Retirement) |
Yes (limited military exception) | Ordinary income tax (1%–12.3%). No general pension exemption. Military retirees may exclude up to $20,000/year (2025–2029) if eligible. |
| 401(k), 403(b), and 457 Plan Distributions (Traditional) |
Yes | Ordinary income tax (1%–12.3%; up to 13.3%). Pre-tax withdrawals fully taxable; early withdrawals may trigger CA 2.5% penalty. |
| Traditional IRA Distributions | Yes | Ordinary income tax (1%–12.3%; up to 13.3%). Taxable portion follows federal rules; nondeductible basis recovered tax-free. |
| Roth IRA Distributions (Qualified) |
No | Tax-free (0%). California conforms to federal qualified Roth IRA treatment. |
| Roth 401(k) Distributions (Qualified) |
No | Tax-free (0%). Qualified withdrawals not included in CA taxable income. |
| Qualified Annuities (Pre-tax Funded) |
Yes | Ordinary income tax (1%–12.3%; up to 13.3%). Entire taxable portion treated like pension income. |
| Nonqualified Annuities (After-tax Funded) |
Partially | Tax on earnings only (1%–12.3%; up to 13.3%). Return of principal/basis is tax-free. |
Does Residency Affect Taxation in California?
| Your Status | Usually Means | California Taxes | Example |
|---|---|---|---|
| Resident | CA is your home or you live there permanently. | Worldwide income. | Live in San Diego → CA taxes wages, investments, retirement, and rental income. |
| Part-Year Resident | You moved into or out of CA during the year. | Worldwide income while a CA resident + CA-source income while a nonresident. | Move from Arizona to CA in July → CA taxes income earned after moving. |
| Nonresident | Your home is outside California. | CA-source income only. | Live in Nevada → CA taxes California wages, rental income, or business income. |
Full-year residents
California taxes residents on everything, regardless of where the income originated.
All residents are taxed on all income, including income sourced from outside California.
Tax Tip: Once you become a full-year California resident, your pension is generally taxed by California even if it comes from an employer in another state.
But, Social Security benefits remain exempt. Military pensions follow the same residency rule but may qualify for California’s new $20,000 military retirement income exclusion, if eligible.
Part-year residents
If you move into or out of California mid-year, the tax treatment splits along the calendar.
- During the months you’re a resident, everything is taxable, regardless of source.
- During the months you’re not, only California-source income is taxable.
Example:
A taxpayer moved to California on May 1 and received an out-of-state pension of $2,000 per month.
Before The Move: The January through April payments ($8,000) were received while the taxpayer was not a California resident, so they were not subject to California income tax.
After The Move: The taxpayer received eight monthly payments from May through December, totaling $16,000. Because these payments were received while the taxpayer was a California resident, the $16,000 is taxable by California.
Tax Planning Strategies for California Retirees
Given how few exemptions California offers, most planning here comes down to timing and account structure rather than finding a loophole.
None of these strategies eliminate California’s tax reach entirely; that’s simply not on offer here.
But combined and coordinated with federal planning, they can somewhat meaningfully soften what is, by most state comparisons, one of the less forgiving tax environments for retirement income in the country.
