This sales tax rate calculator is powered by the same technology used by our sales tax software, except that this tool does not scrub the provided address against the US Postal Service database. Use it to calculate sales tax for any address in the United States. It’s perfect if you need to look up the tax rate for a specific address or zip code. It’s a simple tax rate finder for all US address locations, that returns data based on state and local tax rates.

For any address, you can find the state sales tax rate, as well as all local sales tax rates, and the combined total effective tax rate.

We are happy to offer this tool free of use for anyone needing to find a tax rate by address or who needs a sales tax calculator.

Rates returned by this calculator are deemed accurate but not guaranteed. Do not construe this information as professional or legal advice. Your use of this tool does not imply a professional relationship.

How Does this Sales Tax Calculator Work

In order to determine the correct tax rate, we first need to pinpoint the address to rooftop accuracy. Normal address-related boundaries such as cities and ZIP Codes are different than sales tax boundaries, so trying to use just the address components themselves doesn’t work.

When you enter an address above, we “scrub” it using US Postal Service address data, along with our geotargeting service, to determine the correct sales tax rate for the specific location you request. If you enter an invalid address, however, we will fall back to USPS’s “preferred city”.

Once we know the exact location, we can provide a breakdown of all taxes that apply to a given address. Depending on the location, this may include state sales tax, county sales tax, city sales tax, shopping district taxes, transit authority taxes, and more. The sum of all applicable rates is the effective, total sales tax rate for that location.
