How our sales tax calculator works

1

Enter the base price

Type the pre-tax price. This is the amount before any sales tax is added, usually shown as the subtotal on a receipt.

2

Choose your state

Select your state from the dropdown. The calculator uses the most recent combined state and average local sales tax rate.

3

Add or remove tax

Switch between Add Tax (to compute the total with tax included) and Remove Tax (to extract the pre-tax price from a tax-inclusive total).

Key things to know about our sales tax calculator:

  • Sales tax rates: Range from 0% (DE, MT, NH, OR) to over 9.5% (CA, LA, TN). Most states allow local add-ons, so city rates can be 1-2% higher than state rates.
  • Tax on tax: Some jurisdictions require tax on shipping fees or service charges. Check your local rules for edge cases.
  • Use for invoicing: Use the sales tax calculator to generate accurate receipts, file sales tax returns, or set up tax-inclusive pricing.
