Tax Rate
--
Sales tax in the United States varies wildly — from 0% in Oregon to over 9% in parts of Tennessee and Louisiana — so the sticker price is rarely what you actually pay. Pick a state (combined rates for all 50 plus DC built in) or enter a custom rate, type the amount, and see the true total.
How to Use
- Enter the amount: Type the pre-tax price.
- Choose a state: The combined rate appears automatically.
- Or set a custom rate for an exact local rate or a non-US tax like VAT.
- Read the breakdown: Tax and total update live as you type.
How US Sales Tax Works
The US has no national sales tax: 45 states set their own rates, and thousands of counties and cities stack local taxes on top — so the same purchase can cost 6% in one town and 9.5% a few miles away.
Since the 2018 South Dakota v. Wayfair ruling, states can require online sellers to collect tax based on the buyer’s location, so most large stores charge your local rate at checkout. Unlike VAT — collected at every production stage and baked into listed prices — US sales tax hits only at the final sale, on top of the sticker price.
