How to Calculate Sales Tax

One rate, two directions — add it on or back it out.

1

Pick a direction

"Add tax (forward)" starts from a pre-tax price and adds the tax. "Remove tax (reverse)" starts from a tax-included total and works out what the tax was.

2

Enter the amount and rate

Type the amount and the tax rate as a percentage, or click a state in the table to fill in its base rate. Remember to add local rates for an exact figure.

3

Read the breakdown

The pre-tax amount, sales tax, and total update instantly as you type, so you can compare rates or check a receipt in seconds.

Frequently Asked Questions

How do I calculate sales tax?
Multiply the pre-tax price by the tax rate as a decimal (rate ÷ 100), then add it to the price. For example, $100 at 8% is $100 × 0.08 = $8 tax, for a $108 total.
How do I calculate reverse (backward) sales tax?
Divide the tax-included total by 1 plus the rate as a decimal. A $108 total at 8% is $108 ÷ 1.08 = $100 pre-tax, so the tax was $8.
Does this include local sales tax?
The rate table lists each state's base rate only. City, county, and district taxes add on top, so your actual rate may be higher. Enter your full combined rate for an exact figure.
Which states have no sales tax?
Five states have no statewide sales tax: New Hampshire, Oregon, Montana, Alaska, and Delaware. Alaska still allows local sales taxes.
