Overview

California uses progressive rates from 1% to 13.3%. Understanding how California’s tax system works helps you accurately predict your paycheck and plan your finances throughout the year.

2025 Tax Rates

California uses a progressive income tax structure. Lower income is taxed at lower rates (starting at 1%), and higher income is taxed at higher rates (up to 13.3%). Only the income in each bracket is taxed at that bracket’s rate — not your entire income.

Standard Deduction

California provides a state standard deduction of $4,803 for single filers and $9,606 for married filing jointly. This amount is subtracted from gross income before your state tax rate is applied, lowering your overall state tax burden.

Who Must File in California?

Generally, any resident of California who earns income above the filing threshold must file a state income tax return. The California Department of Revenue sets annual filing thresholds, which roughly correspond to the standard deduction amounts.

How California Tax Affects Your Paycheck

Your employer withholds California state income tax from each paycheck based on your W-4 equivalent form and expected annual income. On a $75,000 annual salary, a single filer in California can expect to pay approximately $4,266–$9,336 in state income taxes annually.

Tips to Reduce Your California State Tax Bill

  • Contribute to a pre-tax 401(k) — reduces both your federal and state taxable income
  • Maximize HSA and FSA contributions if available through your employer
  • Claim all applicable deductions — California may allow deductions beyond the standard deduction
  • Review your withholding each year to avoid underpayment penalties

Filing Deadlines

California’s state income tax return is generally due on April 15, aligning with the federal deadline. An automatic extension to October 15 is usually available, but any tax owed must still be paid by April 15 to avoid penalties.

How California Compares to Neighboring States

California borders Oregon, Nevada, Arizona. Compared to its neighbors, California’s top rate of 13.3% places it among the higher-tax states in the region.
