State base vs. combined rate

The rate shown is each state's statewide base sales tax. Most places add county and city taxes on top, so the rate on your receipt is usually higher. Enter your local add-on to get the combined rate. Five states — Alaska, Delaware, Montana, New Hampshire, and Oregon — have no statewide sales tax. Rates change, so verify against your state's current schedule.

How it’s calculated

Tax = amount × (state base rate + local rate). State base rates are statewide figures; local taxes vary by address.

Worked example

$100 in California at the 7.25% base rate is $7.25 tax for $107.25, before any local add-on.

Common mistakes

  • Treating the state base rate as the final combined rate.
  • Forgetting five states have no statewide sales tax.

Where it is used
