Sales tax calculator
To add sales tax, multiply the price by the rate and add it on: $100 at 8.25% is $108.25. To back tax out of a total, divide the total by one plus the rate: $108.25 divided by 1.0825 is $100. Enter the amount and your combined state and local rate.

Rates vary by address. Check your state's rate lookup for the exact rate. An estimate, not tax advice.
How do I calculate sales tax?
Multiply the price by the rate. Then add that to the price. The rate is your state rate plus any county, city and special district rates for the place of sale, so two stores in the same state can charge different totals.
How do I calculate sales tax backwards?
If you only have the total, divide it by one plus the rate. A $54.13 receipt at 8.25% was $50.00 before $4.13 of tax. Owners use this to split card deposits and marketplace payouts into sales and tax collected.
| State | Statewide rate |
|---|---|
| Texas | 6.25%, up to 8.25% with local |
| Florida | 6% plus county surtax |
| California | 7.25% plus district taxes |
| New York | 4% plus local |
| Delaware, Montana, New Hampshire, Oregon, Alaska | No statewide sales tax (Alaska allows local) |
