California taxes your income on a sliding scale, not a flat rate
California does not have a single income tax rate. Instead, it uses a progressive tax system where the percentage you pay increases as your income rises. The state has 13 tax brackets, ranging from 1% on the lowest incomes to 13.3% on the highest. The rate you pay depends on which bracket your taxable income falls into, not on your total earnings.
This means two people earning different amounts will pay different percentages. Someone earning $20,000 pays a lower rate than someone earning $200,000. You only pay the higher rate on the income that falls into that bracket — not on all your income.
California also adds a 1% Mental Health Tax on income over $1 million, which is separate from the regular brackets. This brings the top rate to 13.3% for the highest earners.
Key Takeaways
- California's tax brackets range from 1% to 13.3%, and the rate you pay depends on your filing status and total income.
- You only pay the higher rate on income that falls into the higher bracket, not on all your earnings.
- The 2024 tax brackets are adjusted each year for inflation, so the income ranges that trigger each rate change annually.
- Your filing status — single, married filing jointly, head of household — determines which bracket your income falls into.
- A 1% Mental Health Tax applies to income over $1 million on top of the regular tax brackets.
The 13 tax brackets and how they work
California's Franchise Tax Board publishes the tax brackets each year, adjusted for inflation. For the 2024 tax year, the brackets for a single filer start at 1% on income up to roughly $10,000, then move through 2%, 4%, 6%, 8%, 9.3%, 10.3%, 11.3%, 12.3%, and 13.3%. Each bracket has a different income range, and those ranges shift slightly each year.
The brackets are different for married couples filing jointly, heads of household, and married people filing separately. A married couple filing jointly reaches the top bracket at a higher income level than a single person does, which is why filing status matters.
To find your bracket, you take your taxable income — not your gross income — and match it to the range for your filing status. Taxable income is what remains after you subtract deductions and credits. The Franchise Tax Board publishes a tax table each year that shows the exact brackets and the tax owed at each level.
Why California's rate is higher than many other states
California's top rate of 13.3% is among the highest in the country. Only a handful of states have rates that high or higher. This reflects California's approach to funding state services through income tax rather than relying as heavily on sales tax or property tax as other states do.
The Mental Health Tax, added in 2021, was designed to fund mental health and substance use disorder services. It applies only to income over $1 million, so it affects a smaller portion of filers than the regular brackets do.
How to find your exact tax bracket and what you owe
The Franchise Tax Board website publishes tax tables and bracket information each year. You can also use the state's tax calculator or work with a tax preparer to determine your bracket based on your filing status and taxable income.
Your W-2 or 1099 shows your gross income, but your taxable income is lower once you subtract the standard deduction or itemized deductions. California allows you to claim the same deductions as the federal government, plus some state-specific ones. Once you know your taxable income, you can look it up in the bracket table for your filing status.
If you owe California state income tax, it is withheld from your paycheck if you are an employee, or you pay estimated tax quarterly if you are self-employed. The amount withheld depends on the W-4 form you file with your employer.
Deductions and credits that lower your taxable income
California allows you to reduce your taxable income through deductions. The standard deduction for 2024 varies by filing status and age — it is higher if you are 65 or older. You can also itemize deductions if they exceed the standard deduction, though fewer people do this since the standard deduction increased in recent years.
Tax credits are different from deductions. A credit reduces the tax you owe dollar-for-dollar, while a deduction reduces the income that is taxed. California offers credits for things like dependent care, education expenses, and low-income workers. These can significantly lower your final tax bill.
Special situations: Self-employed and business income
If you are self-employed, you pay California income tax on your net business income using the same brackets as employees. However, you also owe self-employment tax to the federal government (Social Security and Medicare), which is separate from income tax. California does not have a separate self-employment tax.
Business owners can deduct business expenses — supplies, equipment, rent, wages — before calculating taxable income. This can lower the bracket you fall into. You file Schedule C with your California return to report business income and expenses.
How inflation adjustments change your bracket each year
California adjusts the income ranges for each bracket annually based on inflation. This means the dollar amount that triggers each rate changes every year, usually upward. In years with high inflation, the adjustments are larger.
This adjustment is important because without it, people earning the same amount in real terms would move into higher brackets over time straightforward due to inflation — a phenomenon called bracket creep. The annual adjustment prevents that from happening automatically, though your income may still grow faster than inflation and move you into a higher bracket.
Frequently Asked Questions
Do I have to pay California income tax if I live out of state but work in California?
Yes, if you earned income in California, you owe California tax on that income regardless of where you live. California taxes residents on all income and nonresidents on California-source income only. You may be able to claim a credit on your home state's return for taxes paid to California to avoid double taxation.
What is the difference between California's tax rate and the federal tax rate?
California and the federal government both tax income, but they use separate tax systems with different brackets and rates. You pay both. Federal tax is withheld from your paycheck separately from California tax. Your federal return and California return are filed independently, though the income reported is usually the same.
Does California tax retirement income and Social Security?
California does not tax Social Security benefits. Retirement income from pensions and 401(k) withdrawals is taxed as ordinary income using the same brackets. If you receive a pension from a government employer, some or all of it may be exempt from California tax under specific rules.
How do I know if I owe California income tax?
You owe California income tax if your income exceeds the threshold for your filing status and age. The threshold is based on the standard deduction. If your income is below the standard deduction, you generally do not owe tax. The Franchise Tax Board website lists the current thresholds for each filing status.
Can I reduce my California tax by moving to another state?
If you move out of California, you stop owing California tax on income earned after you leave, but you still owe tax on income earned while you were a resident. California considers you a resident based on where you maintain a home and where your financial and personal ties are located, not just where you claim residency.
