Sales Tax FAQ

What is the average sales tax rate in the US?▼
The average combined state and local sales tax rate in the US is about 7.12%. Rates vary from 0% (Oregon, Montana, Delaware) to over 10% in some localities.
How do I find the pre-tax price from a total?▼
Divide the total by (1 + tax rate as decimal). For example, if total is $108 with 8% tax: $108 / 1.08 = $100 pre-tax price.
