Sales Tax API Terms of Use


The Minnesota Department of Revenue offers a Sales Tax Application Program Interface (hereafter “Sales Tax API”) that provides sales tax rate information upon receipt of a nine-digit ZIP code. The Sales Tax API is used to find the general state and local sales tax rate for any location in Minnesota. The results do not include special local taxes—such as admissions, entertainment, liquor, lodging, and restaurant taxes—that may also apply. This document covers the terms of service and technical documentation pertaining to the Sales Tax API.

Registration and Limits

Subscriber and Registration

A subscriber is a person or organization registered with the department to gain access to the Sales Tax API.

To access the Sales Tax API as a subscriber, you must provide certain information (such as identification or contact details) as part of the registration process for the Sales Tax API, or as part of your continued use of the Sales Tax API. Any registration information you give to the department must always be accurate and kept up-to-date.  You will inform us promptly of any updates.

Permitted Access

Once you have registered, the department will give you a subscriber ID and password.   You may not share the subscriber ID with others outside your organization, nor may you package, distribute, or sell it to any other person or entity.  Your subscriber ID is for you or your company to use in accordance with the transaction limit of 100 transaction per 15 minutes. The counter is reset every 15 minutes.  After the reset, the system will respond to new requests.

Note to software distributors and developers: If you plan to distribute software with the Sales Tax API embedded, please be aware of the transaction limit set for each subscriber.

Service Terms

Any subscriber choosing to use the Sales Tax API should have the tools and staff available to support their process. The department does not provide training or implementation services related to the Sales Tax API.

Availability and Downtime

The Sales Tax API is available 24 hours a day, 7 days a week, except during monthly system patching or downtime as part of application updates. Subscribers can sign up to receive email updates about alerts and details regarding downtime.


Modifications to Sales Tax API are available in the test region for 30 days before a production release with exception to urgent issues. Subscribers can sign up to receive email updates about changes.

The department may modify the terms or any portion of the terms; for example, to reflect changes to the law or changes to the Sales Tax API. You should look at the terms regularly. We'll post notice of modifications to the terms within the documentation of Sales Tax API through email. Changes will not apply retroactively and will become effective no sooner than 30 days after they are posted. But changes addressing new functions for the Sales Tax API or changes made for legal reasons will be effective immediately. If you do not agree to the modified terms for the Sales Tax API, you should discontinue your use of the Sales Tax API. Your continued use of the Sales Tax API constitutes your acceptance of the modified terms.
