      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 with our California paycheck calculator, 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, much like our hourly to salary calculator.

      Gross Income: Type your pay before any taxes come out. Match it to the pay frequency you picked above. Not sure of the figure? Try the gross pay calculator or the annual income calculator.

      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. The taxable income calculator shows how each choice moves your bottom line.

      Total Itemized Deductions: Only shows if you chose itemized. Enter the full amount of your write-offs, like mortgage interest and gifts to charity. Homeowners can estimate the tax piece with the property tax calculator.

      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 — see the traditional IRA calculator for growth over time.

      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. Your AGI calculator result helps you sanity-check this line.

      Estimated Tax Credits: Add any credits you expect. They come off your California tax first, then your federal tax. Expecting money back? Check the tax refund calculator.

      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 — handy alongside the biweekly paycheck calculator — 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

      1. Start with gross pay. This is your pay before anything is taken out.
      2. Subtract pre-tax items. A traditional 401(k) and a deductible traditional IRA lower the income California taxes.
      3. Subtract a deduction. You take either the California standard deduction (much smaller than the federal one) or your itemized deductions — whichever is bigger.
      4. Apply the brackets. Each slice of income is taxed at its own rate.
      5. 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 (see the Social Security tax calculator).
      • Medicare — 1.45% of all wages, plus 0.9% more on high wages. Both are covered in the payroll tax calculator.
      • 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 — the California sales tax calculator shows how local rates stack up.

      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, which you can model with the bonus tax calculator.

      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 — the self-employment tax calculator and 1099 tax calculator handle that case.

      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 — use the tax withholding calculator.
      • Watch your investment sales. Gains are taxed as ordinary income in California, so run the numbers with the capital gains tax calculator.

      Thinking of moving? Compare California with a no-income-tax state using the Texas paycheck calculator or the Florida paycheck calculator, and weigh housing and daily costs with the cost of living calculator. For a plain look at any state's rules, try the state tax calculator.

      These numbers are estimates for planning. Your real tax return can differ. Talk to a tax pro or check the California Franchise Tax Board (FTB) for your exact case.

      Frequently asked questions

      Does this calculator show my tax refund or how much I owe?

      No. It shows your total tax bill for the year, not your refund. A refund depends on how much was already taken out of your paychecks. If your withholding was more than the tax shown here, you get money back. If it was less, you owe.

      Should I put my Roth 401(k) money in the 401(k) box?

      No. The 401(k) box is for traditional (pre-tax) money only. Roth 401(k) and Roth IRA money is put in after tax, so it does not lower your taxable income this year. Leave those out or your results will be too low.

      What is the California SDI rate for 2025?

      It is 1.2% of all your wages. There is no wage cap. The cap was removed starting in 2024, so high earners pay SDI on every dollar. Before 2024, only wages under a yearly limit were charged.

      What is the highest California tax rate?

      The top bracket rate is 12.3%. On taxable income over $1 million, a 1% Mental Health Services Act surtax is added, so the top rate becomes 13.3%. The calculator adds this surtax for you.

      How big is the California standard deduction?

      For 2025 it is $5,732 for Single and Married Filing Separately, and $11,464 for Married Filing Jointly and Head of Household. That is much smaller than the federal standard deduction, which is why many people owe California tax even with low federal tax.

      How much are the California exemption credits worth?

      For 2025 the personal exemption credit is $154 per filer ($308 for joint filers) and each dependent adds $475. These come straight off your California tax bill, not off your income.

      Why does adding a dependent lower my federal tax so much?

      Each dependent adds the federal Child Tax Credit of up to $2,000. That is a dollar-for-dollar cut in federal tax. It starts to shrink once income passes $200,000 ($400,000 for joint filers). California's dependent credit is much smaller.

      Why doesn't the Other Pre-Tax Deductions box lower my California tax?

      That box is for items California does not follow, like some federal-only pre-tax benefits. It cuts your federal income only. Use the 401(k) and IRA boxes for things that lower both federal and California income.

      Can I enter more than 12 dependents?

      No. The stepper stops at 12. If you have more, the extra dependent credits are small, so add them by hand to the Estimated Tax Credits box (about $475 each for California in 2025).

      Does this work for self-employed or 1099 income?

      Not exactly. This tool figures FICA at the employee rate of 7.65%. Self-employed people pay both halves (15.3%) and can deduct half. Use a self-employment tax tool for that. The California bracket math here still applies.

      I moved to California in the middle of the year. Can I still use this?

      Only as a rough guide. The tool treats you as a full-year California resident. Part-year residents and nonresidents file Form 540NR and only pay California tax on part of their income, so your real bill will be lower.

      Does the calculator include CalEITC or the renter's credit?

      No. Credits like the CalEITC, Young Child Tax Credit, and renter's credit are not built in. If you qualify, type the amount into the Estimated Tax Credits box. It comes off your California tax first.

      Are the employer taxes in the Taxberg exact?

      They are close estimates. Social Security (6.2%) and Medicare (1.45%) are fixed. FUTA, California UI, and ETT are charged only on the first $7,000 of wages, and the UI rate here uses the 3.4% new-employer rate. Older companies often pay a different UI rate.

      How accurate is the state-by-state comparison table?

      It is a rough estimate for ranking states, not a filing tool. It holds your federal tax and FICA steady and uses each state's main brackets and standard deduction. It leaves out local city taxes, special credits, and state payroll taxes like SDI in other states.

      Do California cities charge their own income tax?

      No. No California city or county charges a personal income tax. Living in Los Angeles, San Diego, San Jose, or San Francisco does not change your state income tax. Some cities charge business or payroll taxes, but those hit employers, not your paycheck.

      Does California tax my Social Security benefits?

      No. California does not tax Social Security retirement benefits. The federal government may tax part of them. This calculator is built for wage income, so it is not the right tool for a retiree living mostly on benefits.

      Why does my number change when I switch tax years?

      Every year has its own brackets, standard deductions, credit amounts, Social Security wage base, and SDI rate. Brackets get adjusted for inflation, so the same salary usually shows a slightly lower tax in a later year.

      Can I use this to see the tax on a bonus or a raise?

      Yes. Add the bonus or raise to your gross income and compare the new take-home pay to the old one. The next-dollar box below your results also shows the tax on an extra $1,000 right away.

      What if I picked itemized but my total is small?

      The tool protects you. It uses the larger of your itemized total or the standard deduction, for both federal and California. Since California's standard deduction is small, itemizing helps in California more often than it does federally.
