Frequently asked questions
What are California's 2024 income tax brackets?
Single: 1% ($0–$10,412), 2% ($10,412–$24,684), 4% ($24,684–$38,959), 6% ($38,959–$54,081), 8% ($54,081–$68,350), 9.3% ($68,350–$349,137), 10.3% ($349,137–$418,961), 11.3% ($418,961–$698,274), 12.3% ($698,274–$1M), 13.3% (above $1M). The 13.3% rate includes the 1% Mental Health Services Tax on income above $1 million.
Does California tax Social Security benefits?
No — California does not tax Social Security benefits, unlike the federal government (which taxes up to 85%). California also does not tax SDI benefits received. However, pension income, IRA distributions, and 401k withdrawals are fully taxable by California.
Does California have AMT?
Yes — California has its own Alternative Minimum Tax at 7% (compared to federal AMT of 26–28%). California's AMT applies if your regular CA tax falls below the AMT calculation. Most middle-income taxpayers are not affected, but those with large itemized deductions or incentive stock options may be.
When is the California tax deadline?
April 15 (same as federal), or October 15 with an automatic 6-month extension (extension to file only — taxes owed must be paid by April 15 to avoid penalties). California FTB charges 5% penalty per month for late filing, plus 0.5% per month for late payment.

CA vs Federal: key conformity differences
California does not conform to: 401k/403b pre-tax treatment (CA taxes these contributions now), federal bonus depreciation (CA uses its own depreciation schedule), the $10K SALT cap (no California analog), Roth IRA income limits (CA follows federal here). California does conform to: HSA treatment, mortgage interest deduction, charitable contribution deduction.
