How to use US Sales Tax by State

  1. Pick your state — its 2025 statewide base sales-tax rate loads automatically.
  2. Add your local city/county rate in the local-rate field to get the full combined rate.
  3. Choose a mode: 'Add tax' to add tax onto a price, or 'Remove tax' to pull it out of a tax-inclusive total.
  4. Read the total at the top and the net / tax / gross breakdown below.

Common use cases

  • Checkout totals. Add your state and local sales tax to a shelf price so you know exactly what you'll pay at the register.
  • Receipts and reimbursement. Reverse the tax out of a tax-inclusive total to find the pre-tax price for expense reports and accounting.
  • Pricing across states. Compare what the same product costs after tax in different states when the base rates differ.

Tips

  • The built-in figures are statewide base rates — most cities and counties add a local rate on top, so enter yours for the exact total.
  • Five states levy no statewide sales tax: Alaska, Delaware, Montana, New Hampshire and Oregon (though some Alaska localities charge a local tax).
  • Use 'Remove tax' whenever a price already includes tax and you need the pre-tax amount.

Troubleshooting

The total is lower than what I actually paid.
The state figure is only the base rate. Add your city and county rate in the local-rate field — combined rates can be several points higher.
My state shows a 0% base rate.
That state has no statewide sales tax. If your locality charges a local tax (as some Alaska boroughs do), enter it in the local-rate field.
Reversing tax by subtracting the percentage gives a different number.
Tax is charged on the net price, so you divide the gross by (1 + rate) rather than subtracting the percentage. The tool does this correctly.

Frequently asked questions

Are the state sales tax rates up to date for 2025?
Yes. Each state's 2025 statewide base rate is built in. Local city and county rates change more often and vary by location, so you enter those yourself.
Why is the tax lower than what I paid in a store?
The state rate is only the base. Most cities and counties add a local sales tax on top — enter your local rate to get the exact combined total.
Which states have no sales tax?
Alaska, Delaware, Montana, New Hampshire and Oregon have no statewide sales tax. Some Alaska localities still charge a local sales tax.
How do I find the price before tax?
Switch to 'Remove tax' mode and enter the tax-inclusive total. The tool divides by (1 + combined rate) to give the correct pre-tax price.
Is anything I enter uploaded?
No. The calculator runs entirely in your browser — nothing is sent to a server.
