Sales tax is a consumption tax charged on the sale of goods and certain services. In the United States, sales tax is imposed by state and local governments, resulting in varying rates across the country. There is no federal sales tax.
Sales tax rates range from 0% in states like Oregon, Montana, and Delaware to over 10% in some cities when combining state, county, and city taxes. The combined rate is the sum of all applicable tax jurisdictions. Five states have no state sales tax, but some localities within those states may impose their own.
The formula is straightforward: Tax Amount = Pre-Tax Price x Tax Rate. To find the pre-tax price from a total, use: Pre-Tax Price = Total / (1 + Tax Rate). This reverse calculation is useful when you know the total paid and need to determine how much was tax.
