California has the highest statewide base sales tax rate in the U.S. – 7.25% – and local district taxes bring the total to between 7.25% and over 10.5% depending on where you buy, for example about 9.5–9.75% in Los Angeles. Local rates change often – check your exact rate with the state revenue department for large purchases.

Tips

  • Tax figures here are estimates for planning – your actual tax depends on credits, deductions and local rules.
  • Check the tax year and filing status before you rely on a result.
  • Use gross (before-tax) figures unless a field asks for take-home pay.
  • When in doubt, confirm with the tax authority’s own calculator or a tax professional.

Common mistakes to avoid

  • Confusing marginal and effective tax rates.
  • Adding sales tax to a price that already includes it.
