California uses progressive tax brackets. The rate shown is the TOP marginal rate, not your actual effective rate — your real state tax bill will likely be lower than this estimate suggests, especially at lower incomes.
Estimates based on 2026 published rates. State tax law changes frequently — verify current figures with your state's Department of Revenue. Not tax advice.
What is this tool?
Provides a rough estimate of US state income tax based on your income and state of residence, since state tax rates and structures vary widely — some states have no income tax at all.
How to use it
Select your state and enter your income, and an estimated state tax liability is calculated based on that state's general rate structure.
State tax rules include many state-specific deductions and credits this general estimate can't account for — treat the result as a starting point for planning, not a substitute for your actual state tax return.
