Frequently Asked Questions
What is a GIS?
One of the primary elements of the SUTS System allows businesses to easily, and with the aid of free technology, identify the correct taxing jurisdictions related to the sale of a taxable good or service. The Geographic Information System (GIS) now allows businesses to look up the specific sales tax rate for an individual address. The GIS not only shows state sales tax information, but it also includes sales tax information for counties, municipalities, and special taxation districts. This system allows for a complete tax rate to be determined so the correct tax is collected from customers in real-time.
Also, if your internal point of sale system supports it, the GIS information can be accessed through an Application Programming Interface (API).This API can automatically reference current tax information directly from the CDOR. Please note that the Department will need to verify that you have registered for an account for the Remittance Portal before using the API. Additionally, in some instances, the base map from Google cannot resolve some queries where, for example, “county road” is abbreviated as C.R. This issue is being investigated by Google Maps staff and should be resolved shortly.
What is an API?
The new GIS includes an API, which is short for "application programming interface," which is a software intermediary that allows two systems to talk to one another. An API assists you in automating your point of sale (POS) system by automatically retrieving the most up-to-date sales tax rate calculation information from the GIS database for the transaction.
How do I integrate and use the SUTS API?
Once you have fully registered for the Sales & Use Tax System (SUTS) at Colorado.gov/Revenue/SUTS, you can email an access request to the E-File Unit at firstname.lastname@example.org. Please include your Colorado Account Number (CAN) in the subject line of the email request.
Once the E-File Unit verifies your SUTS registration, you will receive an "API key" via email. This digital key is a string of letters and numbers that will be unique to you/your business. Please note that third-party, pre-packaged, point of sale systems typically do not allow API key customization. The API key is for businesses that have their own point of sale systems and software.
