What It Does
Calculate sales tax for any US state or Canadian province. Select your state or province to apply the correct rate, then choose whether to add tax to a net amount or remove tax from a gross amount.
Worked Example
Adding 6.25% Texas state tax to $100: tax = 100 × 0.0625 = $6.25. Gross price = $100 + $6.25 = $106.25. Removing tax: $106.25 ÷ 1.0625 = $100.

Local Context
US sales tax rates vary by state from 0% (Alaska, Delaware, Montana, New Hampshire, Oregon) to 7.25% (California). Canada uses GST (5% federal) or HST (11-15% combined) depending on the province. Quebec also charges QST (9.975%) on top of GST. Unlike EU VAT which is included in displayed prices, US and Canadian sales taxes are typically added at checkout.
