About SalesTax4Me

SalesTax4Me is a free US sales tax calculator covering all 50 states and Washington D.C. Calculate the tax on any purchase, reverse-calculate the pre-tax price from a receipt total, build a shopping cart, and explore every state's combined rate.

We use combined rates (state + average local) from Tax Foundation and Sales Tax Institute data, updated for 2024/2025. All calculations run in your browser — no data is collected or sent anywhere.

Rates shown are combined state + average local rates. Your actual rate depends on your specific city and county. We are not tax professionals. Always verify with your local tax authority or a qualified accountant for business use.
