Divide to remove · combined rates apply

Rates vary by state, county and city, and combined rates in the same state can differ by several points. Some goods are exempt or taxed at a reduced rate. Check the rate for the exact address of the sale.

Sales tax is the price multiplied by the rate. A $100 item at 7% costs $107. Working backwards, divide the total by 1.07 rather than subtracting 7%, which would give $99.51 and be wrong.

How to calculate sales tax

1 Choose whether you are adding tax or removing it.

2 Enter the amount and the combined rate for the location.

3 Read the tax and the total separately.

4 Use the combined state plus local rate, not just the state figure.

Combined rates are what actually apply, and they are rarely the state rate alone. A state at 6.25% can have counties and cities adding two or three points on top, so the rate at one address differs from the rate a few miles away. Sourcing rules add another layer: most states tax based on where the buyer takes delivery rather than where the seller sits, which is why online sellers deal with thousands of rate combinations rather than fifty.
