🧮 Sales Tax Calculator
Official 2026 state sales tax rates for all 50 states + DC (Tax Foundation, as of Jan. 1, 2026).
About These Rates
The "average combined rate" is the statewide rate plus a population-weighted average of local (city/county) rates, sourced from the Tax Foundation's 2026 state and local sales tax report. Actual local rates vary significantly by city and county — for an exact rate, check your local jurisdiction or use the custom rate option.
Frequently Asked Questions
Which US states have no sales tax?
Five states have no statewide sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon. Alaska
does allow local governments to levy their own sales taxes, so some Alaska municipalities still have a
small combined rate.
Why does my local rate differ from the state rate?
Most states allow cities, counties, and special districts to add their own local sales tax on top of the
state rate. This is why the same state can have very different combined rates from one city to the next —
the "average combined rate" here is a population-weighted state average, not any single city's exact rate.
Guide: understanding your result
- Sales tax = price × combined rate (state + county + city + special districts).
- States without a statewide sales tax: Alaska, Delaware, Montana, New Hampshire, Oregon (some allow local sales taxes).
- Many states exempt or reduce tax on groceries and prescription drugs.
Worked example
A $1,200 purchase at a combined rate of 8.25% costs $99.00 in tax, for a total of $1,299.00. To remove tax from a total, divide by (1 + rate): $1,299.00 ÷ 1.0825 = $1,200.00.
