How this calculator works
Sales tax is the price multiplied by the combined rate — the state rate plus any city, county or special-district rate. To find the price before tax inside a total, divide the total by 1 plus the rate.
State rates are from the Tax Foundation’s July 1, 2026 table. Local rates vary by address, so enter yours for an exact figure. Many states exempt or reduce tax on groceries and some other items.
Assumptions and tips
- The item is fully taxable at the general rate.
- Alaska, Delaware, Montana, New Hampshire and Oregon have no statewide sales tax, though some Alaska localities do.
Worked example
Using the default values in the calculator above:
| Input | Value |
|---|---|
| Calculation | Add tax to a price |
| Amount | $100 |
| State | Texas |
| Local (city/county) rate | 0 % |
| Result | Value |
|---|---|
| Total with tax | $106.25 |
| Sales tax | $6.25 |
| Combined rate used | 6.25 % |
| State rate | 6.25 % |
| Typical combined rate (state + average local) | 8.2 % |
Step by step:
- Combined rate = state rate + local rate
- Tax = $100 × rate ÷ 100
- Total = price + tax

Common mistakes to avoid
- Using only the state rate — in most states, city and county taxes add 1–5 percentage points.
- Subtracting the rate from a tax-included total (e.g. $108.25 − 8.25%) instead of dividing by 1.0825.
