🌴 What is the California Income Tax?
California imposes a state income tax on all residents using a progressive bracket system with 10 tax rates ranging from 1% to 13.3%. The 13.3% top rate makes California the highest state income tax jurisdiction in the United States as of 2025. This rate applies only to income above $1 million and includes the 1% Mental Health Services Tax (Proposition 63) that was added in 2004.
Beyond state income tax, California workers pay California SDI (State Disability Insurance) at 1.1% on all wages with no cap since Senate Bill 951 took effect in January 2024. This funds California's paid family leave and short-term disability programs. On top of CA taxes, residents also pay federal income tax and FICA (Social Security at 6.2% and Medicare at 1.45%). For a $100,000 earner, the combined state and federal tax burden is typically 20-25% of gross income.
A common source of confusion is California's standard deduction. For 2025, single filers can deduct $5,202 from their California return, but $15,000 from their federal return. This gap means your California taxable income is about $9,800 higher than your federal taxable income for the same gross income. Workers who contribute to a 401(k) or traditional IRA receive a federal deduction for those contributions but not a California deduction, increasing California taxable income further.
This calculator uses 2025 California FTB (Franchise Tax Board) tax brackets and the 2025 federal brackets from the IRS. It provides an estimate for wage earners with standard deductions. If you have significant itemized deductions, capital gains, business income, or other adjustments, use the official California FTB online estimator or consult a California CPA for precise calculations.

❓ Frequently Asked Questions

What is the California income tax rate for 2025?
California has 10 tax brackets for 2025 ranging from 1% on the first $10,756 of taxable income (single) to 13.3% on income above $1 million. The 13.3% top rate includes the 1% Mental Health Services Tax. Most middle-income Californians fall in the 6% to 9.3% bracket range.
How is California income tax calculated?
California uses a progressive tax system. First, subtract the CA standard deduction ($5,202 for single filers in 2025) from gross income to get taxable income. Then apply the marginal rates: 1% on the first $10,756, 2% on the next tier, and so on up to 13.3%. Only the income within each bracket is taxed at that rate, not all income.
Does California have a state income tax for all residents?
Yes. California imposes a state income tax on all residents earning above the minimum filing threshold. For 2025, single filers with gross income over $18,536 must file. The tax applies to wages, self-employment income, rental income, capital gains, and most other income types.
What is California SDI and how much is it?
California State Disability Insurance (SDI) is a payroll deduction that funds short-term disability and paid family leave benefits. For 2025, the SDI rate is 1.1% with no wage base cap (since SB 951 effective January 2024). On a $100,000 income, SDI is $1,100. On a $300,000 income, SDI is $3,300.
Does California have a standard deduction and how does it compare to federal?
Yes, but California's standard deduction is much lower than the federal deduction. For 2025: CA single standard deduction is $5,202 vs. federal $15,000. CA married filing jointly is $10,404 vs. federal $30,000. This means your California taxable income is substantially higher than your federal taxable income, which is one reason CA residents pay high effective state tax rates.
What is the effective California income tax rate for a $100,000 salary?
At $100,000 for a single filer in 2025: CA taxable income = $100,000 - $5,202 = $94,798. Applying the CA brackets gives approximately $6,060 in CA tax, a CA effective rate of about 6.1%. Federal tax adds another $13,000 to $14,000. SDI adds $1,100. Total effective combined rate is roughly 20-22% of gross income.
Is California the highest taxed state in the US?
California has the highest top marginal state income tax rate at 13.3%, but high-income Californians effectively pay high combined rates. Median-income residents pay effective CA state rates of 4-7%, which is high but not always the highest after accounting for local taxes. States like New Jersey and Connecticut also impose very high combined tax burdens when including property taxes. Hawaii has a high marginal rate (11%) that kicks in at lower income levels.
How do California taxes compare to Texas or Florida?
Texas and Florida have zero state income tax. A California resident earning $150,000 single pays roughly $10,000 to $11,000 in CA state income tax (effective rate about 7%). That same income in Texas or Florida pays $0 in state income tax. However, Texas and Florida have higher property taxes and sometimes higher sales taxes that offset some of the difference.
