Sales Tax API (Application Program Interface)

Subscribe to Sales Tax API email updates. 

The Minnesota Department of Revenue offers a Sales Tax Application Program Interface (Sales Tax API) that connects an online retailer’s sales site and Minnesota’s sales tax rate information, using a nine-digit ZIP code.

Why use the Sales Tax API?

The Sales Tax API is an efficient service that will automatically find the general state and local sales tax rate for any location in Minnesota for each of your sales transactions. You no longer need to do quarterly updates for rates and boundaries information when using the Sales Tax API.

The results do not include special local taxes—such as admissions, entertainment, liquor, lodging, and restaurant taxes—that may also apply. For more information, see Local Sales Tax Information.
