Sales tax in the US
State and local rates
Sales tax is set by state and sometimes county or city. Rates range from 0% (Oregon, Montana) to over 10% in some cities.
Tax-exempt items
Groceries, prescription drugs, and some clothing may be exempt or taxed at a reduced rate depending on your state.
Online purchases
Since the 2018 South Dakota v. Wayfair ruling, most online retailers collect sales tax based on the buyer's location.
Reverse calculation
If you know the total but need the pre-tax amount, use "Remove tax from total" mode — useful for expense reporting.
For estimation only. Actual tax may vary based on jurisdiction and product type. Not tax advice.
