How to use
- 1Pick your state and enter the price.
- 2Use the state's average local rate, or type your exact local rate (find it on your receipt or your state revenue site).
- 3Choose whether the amount is before tax or already includes tax.
How it's calculated
Total = price × (1 + (state rate + local rate) ÷ 100). To back tax out of a total: price = total ÷ (1 + rate ÷ 100).
