California Income Tax: Graduated Brackets Up to 13.3%
California uses a progressive income tax with 9 brackets from 1% to 12.3%, plus the 1% Mental Health Services Tax on taxable income over $1 million, for a top rate of 13.3%, the highest state income tax rate in the US. California first subtracts its own standard deduction ($5,900 single, $11,800 joint or head of household) and then a personal exemption credit ($158 single, $316 joint) from the tax.
Like federal taxes, California's system is marginal — only the income within each bracket is taxed at that bracket's rate. Combined with federal taxes (10%–37%), California residents can face a total marginal rate of up to 50.3% on their highest dollars of income.
California Tax Brackets for 2026 (Single Filer)
The 2026 California brackets for single filers (the FTB schedule indexed 3.4% for inflation) apply to taxable income after the standard deduction:
- 1% on income from $0 to $11,456
- 2% on income from $11,456 to $27,157
- 4% on income from $27,157 to $42,861
- 6% on income from $42,861 to $59,498
- 8% on income from $59,498 to $75,197
- 9.3% on income from $75,197 to $384,109
- 10.3% on income from $384,109 to $460,927
- 11.3% on income from $460,927 to $768,213
- 12.3% on income over $768,213
- +1% Mental Health Services Tax on taxable income over $1,000,000 (13.3% top rate)
Joint filers' bracket thresholds are roughly double. Example: a single filer earning $60,000 has California taxable income of $54,100, owes $1,731 on the brackets and about $1,573 after the $158 exemption credit (2.6% of gross).
Your marginal rate is the rate on your last dollar of income. Your effective rate (total tax divided by total income) is always lower because of the progressive structure.
Tips to Lower Your California Tax
Maximize pre-tax retirement contributions to reduce both federal and California taxable income. The 2026 401(k) limit is $24,500 ($32,500 with catch-up for age 50+). California does not use the federal standard deduction: this calculator applies California's own standard deduction and exemption credit, and ignores California itemized deductions, dependent credits and the renter's credit.
Income Tax Calculator California: 2026 SDI, Mental Health Surtax, and Filing Deadlines
Two California-specific items beyond the base brackets: (1) the State Disability Insurance (SDI) payroll tax — for 2026 the SDI rate is 1.3% on ALL wages with NO wage cap since the cap was permanently removed effective 2024 per SB 951. On a $200,000 salary that is $2,600 in SDI alone. SDI is a payroll tax, so it is not included in this income tax estimate. (2) The 1% Mental Health Services Tax (MHST) surtax adds another 1% on taxable income above $1,000,000, which is what makes the top marginal rate 13.3% (12.3% top bracket + 1% MHST). This calculator includes the MHST. Per the California Franchise Tax Board personal filing page, the 2026 CA return is due April 15, 2027 (automatic 6-month extension to October 15, 2027, but tax owed must still be paid by April 15). Add SDI (1.3% of wages) to the income tax calculator california output for the full-year cost. Last updated: 2026-07-15.
