Sales Tax Calculator

Sales tax is a percentage added to a pre-tax price at the point of sale, and the rate depends on where you buy — the table below gives the statewide base rate for all 50 US states plus the District of Columbia. Add sales tax to a pre-tax price, or back it out of a tax-included total. Enter any rate, or click a state in that table to use its base rate.

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. Sales tax is charged on what you spend from your take-home pay; to work out how much of your paycheck is left after income tax and deductions, use the Paycheck Calculator.

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. The calculator does both halves at once: type the pre-tax amount and the rate, or click a state in the rate table to fill the rate in, and it shows the tax and the tax-included total together. Amounts are rounded to the cent, so a $19.99 item at 8.25% works out to $1.65 tax and a $21.64 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. Switch the calculator to reverse mode and it runs that division for you, reporting the pre-tax price and the tax portion separately — useful for splitting a receipt when only the gross total is printed. Do not subtract the rate from the total instead: taking 8% off $108 gives $99.36, which is 64 cents wrong, because the rate applies to the smaller pre-tax base rather than to the total.
Does this include local sales tax?
Local sales tax is not included — 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. The five are often remembered by the initials NOMAD: New Hampshire, Oregon, Montana, Alaska, Delaware. Alaska is the one that catches people out, because with no state rate its boroughs and cities set their own, so a purchase there can still carry several percent at the register. Delaware charges businesses a gross receipts tax instead, which is built into shelf prices rather than added at checkout.
