Introduction
This California income tax calculator shows what you really take home from your pay. Type in your pay, pick your filing status, and see your federal tax, California state tax, Social Security, Medicare, and State Disability Insurance (SDI) in one place.
It covers tax years 2021 through 2025. You can enter pay by the hour, day, week, two weeks, month, or year. You can also add your 401(k), IRA, dependents, credits, and either the standard deduction or your itemized deductions.
The results show your take-home pay, your marginal tax rate, and your average (effective) tax rate. You also get a full tax breakdown, step-by-step math, charts, a "taxberg" that shows the taxes your employer pays, and a table that compares California to every other state.
Use it to plan a budget, check a paycheck, compare filing as single or married, or see how a raise or a bigger 401(k) changes your tax. All numbers are estimates, so use them as a guide, not as tax advice.
How to use our California Income Tax Calculator
Enter your pay, filing status, and a few deductions. The calculator shows your California tax, federal tax, FICA, SDI, and your take-home pay, plus a step-by-step breakdown and a state-by-state comparison.
Tax Year: Pick the year you want. This sets the tax brackets, standard deductions, credits, and SDI rate used in the math.
Pay Frequency: Choose how you get paid: hourly, daily, weekly, biweekly, monthly, or yearly. The tool turns that into a yearly amount for you.
Gross Income: Type your pay before any taxes come out. Match it to the pay frequency you picked above.
Filing Status: Choose Single, Married Filing Jointly, Married Filing Separately, or Head of Household. This changes your brackets and deduction.
City or County: Type your California city or county. Most places have no local income tax, so you can leave the default.
Deduction Type: Pick the standard deduction or itemized. Standard is the easy choice and works for most people.
Total Itemized Deductions: Only shows if you chose itemized. Enter the full amount of your write-offs, like mortgage interest and gifts to charity.
401(k) Contribution: Enter what you put in your traditional 401(k) for the year. This lowers both your federal and California taxable income.
Traditional IRA Contribution: Enter your yearly IRA amount. The tool checks the income limits and applies the part you can deduct.
Number of Dependents: Use the plus and minus buttons for 0 to 12 dependents. You get a California dependent credit and the federal Child Tax Credit.
Other Pre-Tax Deductions: Enter other federal-only pre-tax amounts. These cut your federal income but not your California income.
Estimated Tax Credits: Add any credits you expect. They come off your California tax first, then your federal tax.
Compare Filing Statuses: Turn the switch on and pick a second status to see both side by side.
Calculate My Taxes: Click it to see your results. Use the pay period tabs to view amounts per hour, week, month, or year, and hit Reset to start over.
California Income Tax: What You Need to Know
California has a state income tax on top of federal income tax. It uses tax brackets, so the more you earn, the higher the rate on your top dollars. Rates run from 1% to 12.3%, plus a 1% extra tax (called the Mental Health Services Act surtax) on taxable income over $1 million. That makes California's top rate one of the highest in the country.
How Your California Tax Is Figured Out
- Start with gross pay. This is your pay before anything is taken out.
- Subtract pre-tax items. A traditional 401(k) and a deductible traditional IRA lower the income California taxes.
- Subtract a deduction. You take either the California standard deduction (much smaller than the federal one) or your itemized deductions, whichever is bigger.
- Apply the brackets. Each slice of income is taxed at its own rate.
- Subtract exemption credits. California gives a personal exemption credit and a credit for each dependent. These come straight off your tax bill, not off your income.
Other Money Taken From Your Paycheck
- Federal income tax: seven brackets from 10% to 37%.
- Social Security: 6.2% of wages, up to a yearly wage limit.
- Medicare: 1.45% of all wages, plus 0.9% more on high wages.
- California SDI: State Disability Insurance, which also pays for Paid Family Leave. Starting in 2024, the wage cap was removed, so all of your wages are charged.
California cities and counties do not charge their own income tax. So living in Los Angeles, San Diego, or San Francisco does not change your state income tax. Sales tax is a different story.
Marginal Rate vs. Effective Rate
Your marginal rate is the rate on your next dollar earned. Your effective rate (or average rate) is your total tax divided by your total pay. The effective rate is always lower, because your first dollars are taxed at low rates. A raise is taxed at your marginal rate, but it never pushes your whole paycheck into a higher rate. The same idea applies to a bonus.
Taxes Your Employer Pays
Your employer also pays taxes on your job that never show on your pay stub: a matching 6.2% for Social Security, a matching 1.45% for Medicare, federal unemployment tax (FUTA), and California unemployment insurance (UI) and Employment Training Tax (ETT). Add these up and the true cost of employing you is more than your salary. If you work for yourself, you pay both halves.
Easy Ways to Lower Your California Tax
- Put more into a traditional 401(k). It cuts both federal and California taxable income.
- Check if a traditional IRA deduction works for you. California follows the federal rules here, and a Roth IRA can still make sense for tax-free growth later.
- Itemize if your deductions beat the small California standard deduction. California still allows some write-offs the federal system limits, like full state and local tax rules being different.
- Claim every dependent credit you qualify for.
- Adjust your withholding so you are not overpaying all year.
- Watch your investment sales. Gains are taxed as ordinary income in California.
