Sales tax isn’t a single national rate — each state sets its own, and local governments add more. Here are the 2026 combined rates (Tax Foundation midyear edition).
Average combined rates by state (2026)
| State | State rate | Avg. local | Combined |
|---|---|---|---|
| Tennessee | 7.00% | 2.61% | 9.61% |
| Washington | 6.50% | 3.07% | 9.57% |
| California | 7.25% | 1.78% | 9.03% |
| New York | 4.00% | 4.54% | 8.54% |
| Texas | 6.25% | 1.95% | 8.20% |
| Florida | 6.00% | 0.98% | 6.98% |
How to calculate it
Tax = Price × combined rate — $200 at 8% = $16 of tax.
The sales tax calculator computes the exact amount for any of the 50 states, including the reverse calculation (what the pre-tax price was).
Rates change at midyear: the data above is the 2026 midyear edition from the Tax Foundation, the standard reference for combined state and local sales tax rates.
