California Tax Calculator

California runs one of the most tiered income tax systems in the country, with more brackets than most states and the highest top marginal rate of any state in the nation. A surtax layers onto the very highest earners as well, and unlike many states, California taxes capital gains as ordinary income rather than at a preferential rate. This calculator walks your income through every California bracket to show your exact state tax.

How California income tax works

  • California applies many brackets in sequence, so your income is taxed in layers as it rises.
  • A surtax applies on top of the standard brackets for income above a very high threshold.
  • Capital gains are taxed the same as ordinary wage income — there's no reduced state rate for long-term gains.

Frequently asked questions

How is California income tax calculated?

California uses a long tiered bracket schedule, so each slice of your income is taxed at its own rate, with an added surtax at the very top. The calculator applies every bracket to your entered income and shows your marginal and effective rates.

Does California tax Social Security benefits?

No. California excludes Social Security benefits from state taxable income.

Does California tax capital gains differently from wages?

No — California taxes capital gains as ordinary income at the same bracket rates as wages, with no reduced rate for long-term holdings. That makes California comparatively expensive for investors selling appreciated assets.

How much state tax will I pay in California?

It depends heavily on your total taxable income, since California's brackets span a wide range of rates. Enter your income above for an exact breakdown.
