Add sales tax to a price, or work backward from a total to the pre-tax price. Pick a state to load its 2026 base rate, then add your local rate for the exact figure.
The formulas
Total = price × (1 + rate). To remove tax from a total: price = total ÷ (1 + rate). Example: $107.25 at 7.25% is $100.00 before tax.
$100 purchase in large states (state rate only)
| State | State rate | Total on $100 |
|---|---|---|
| California | 7.25% | $107.25 |
| Texas | 6.25% | $106.25 |
| New York | 4% | $104.00 |
| Florida | 6% | $106.00 |
| Washington | 6.5% | $106.50 |
| Illinois | 6.25% | $106.25 |
Cities and counties add their own tax on top — combined rates above 9% are common in parts of Louisiana, Tennessee, Arkansas, Washington and Alabama. Alaska, Delaware, Montana, New Hampshire and Oregon have no statewide sales tax.
