California Income Tax Calculator

What Are California Income Tax Brackets?

California uses a progressive income tax system with nine brackets ranging from 1% to 13.3%. Enter your gross pay and filing status in the calculator above to estimate the state tax portion of your paycheck. The 13.3% top rate is the highest state income tax rate in the country, but it applies only to taxable income exceeding $1 million. Most California workers fall in the 4-9.3% range, with the 9.3% bracket covering income from approximately $68,351 to $349,137 for single filers - a wide band that captures most middle-to-upper-middle-class earners.

California Tax Brackets for Single Filers

1%: $0-$10,412. 2%: $10,413-$24,684. 4%: $24,685-$38,959. 6%: $38,960-$54,081. 8%: $54,082-$68,350. 9.3%: $68,351-$349,137. 10.3%: $349,138-$418,961. 11.3%: $418,962-$698,271. 12.3%: $698,272-$1,000,000. 13.3%: above $1,000,000 (includes the 1% mental health services surtax). At $80,000 taxable income: tax approximately $3,800 (effective rate 4.75%). At $120,000: approximately $6,900 (5.75%). At $200,000: approximately $13,700 (6.85%). The 9.3% bracket is the critical range for most professional workers in California.

California Standard Deduction and Exemptions

California standard deduction is much lower than the federal amount: $5,363 for single filers and $10,726 for married filing jointly (2024). The federal standard deduction is $14,600/$29,200. This means more income is taxable at the state level than at the federal level. California personal exemption credit: $144 per person ($288 for married filing jointly). Dependent credit: $433 per dependent. These modest credits do little to offset the high brackets. California does not conform to the federal standard deduction, so workers accustomed to the larger federal deduction are often surprised that their California taxable income is $9,000+ higher than their federal taxable income.

California Capital Gains and Investment Income Tax

Unlike the federal system (which taxes long-term capital gains at preferential 0-20% rates), California taxes all capital gains as ordinary income at the full progressive rate. A California resident in the 9.3% bracket who sells stock for a $50,000 long-term gain: federal tax at 15% = $7,500. California tax at 9.3% = $4,650. Total capital gains tax: $12,150. In Texas (no state tax): total tax $7,500. The California premium on investment income is a major factor for investors, retirees drawing from taxable accounts, and anyone selling appreciated assets. This treatment makes tax-advantaged accounts (Roth IRA, 401(k)) even more valuable for California residents.

How Does California Tax Affect High Earners?

Above $349,137 single: rates jump from 9.3% to 10.3%, then 11.3% at $418,962, 12.3% at $698,272, and 13.3% above $1 million. Combined with the 37% top federal rate and 3.8% net investment income tax: total marginal rate reaches 54.1% on income above $1 million. A tech worker with $1.5 million in total compensation (salary plus RSU vesting): the $500,000 above $1 million is taxed at 13.3% state ($66,500) plus 37% federal ($185,000) = $251,500 in tax on that $500,000 increment alone. This top-end taxation drives high-earner migration to no-tax states and fuels political debate about California competitiveness versus revenue needs.

California Itemized Deductions

California allows itemized deductions but with important differences from federal rules. Mortgage interest: deductible on up to $1 million in acquisition debt (California did not conform to the 2017 federal $750,000 cap). State and local taxes: not deductible on the California return (you cannot deduct state tax paid from state taxable income). Charitable contributions: deductible, generally following federal rules. Medical expenses: deductible above 7.5% of California AGI. Property taxes: deductible on the California return (no state-level SALT cap). These differences mean your California itemized total may be higher or lower than your federal itemized amount depending on your specific deductions.

California Tax Credits That Reduce Your Bill

California Earned Income Tax Credit (CalEITC): up to $3,529 for families with qualifying children and income below $30,950. Young Child Tax Credit: additional $1,117 for CalEITC recipients with a child under 6. Renter Credit: $60 for single filers ($120 MFJ) with AGI below $50,746 ($101,492 MFJ). Child and Dependent Care Credit: percentage of federal credit amount. These credits provide meaningful relief for lower-income California residents but phase out at income levels well below the median household income in expensive metro areas. Higher-income taxpayers have few credits available and bear the full weight of the progressive rate structure.

Filing California State Tax Returns

California tax returns (Form 540) are due April 15, matching the federal deadline. The Franchise Tax Board (FTB) administers state income tax. CalFile (California free e-filing system) is available for simple returns. California conforms to many but not all federal tax provisions - notable non-conformities include HSA deductions (not recognized), the SALT deduction cap (California uses its own rules), and certain business deductions. Part-year residents file Form 540NR and allocate income between California and non-California sources. Former residents who maintain California-source income (rental property, business income, stock options from California employment) continue to owe California tax on that specific income even after establishing residency elsewhere.
