How do I calculate sales tax?

Multiply the pre-tax price by the tax rate as a decimal. A $50 item at 7% sales tax has $50 × 0.07 = $3.50 in tax, for a $53.50 total.

How do I back sales tax out of a total?

Divide the total by (1 + tax rate ÷ 100). A $53.50 total at 7% tax has a pre-tax price of $53.50 ÷ 1.07 = $50, and $3.50 of tax.

Are the state rates here the full rate I'll pay?

These are state base rates only. Cities, counties, and special districts add 1–4% on top in most states. For an exact rate, look up the destination ZIP code on your state revenue department's site.

Which states have no sales tax?

Five states have no statewide sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon. Alaska does allow local sales taxes.

Do I charge tax to out-of-state customers?

If you're a US business, you generally need to collect sales tax in any state where you have economic nexus — most commonly $100k in sales or 200 transactions per year into that state. Check each state's threshold.

Sales Tax Calculator

Add sales tax to a pre-tax price, or back it out of a tax-included total. Pick a US state to auto-fill the base rate, or type your own combined rate (state + local).

Quick answerTo add tax: total = price × (1 + rate ÷ 100). To remove tax: pre-tax = total ÷ (1 + rate ÷ 100). A $50 item at 7% sales tax becomes $53.50; a $53.50 total at 7% tax was $50 before tax.

How sales tax is calculated

Sales tax is a percentage of the pre-tax price, added at checkout. To add: multiply the price by (1 + rate). To back tax out of a total: divide the total by (1 + rate). The rate is the sum of the state rate plus any local (city, county, special district) rates that apply at the buyer's address.
