Sales & Use Tax System (SUTS)

Geographic Information System is Online and Available

Colorado retailers are advised pursuant to sections 39-26-104(3)(c)(III)(B) and 39-26-105.2(2), C.R.S., that the Geographic Information System (GIS) described in those sections is now online and available for retailers to use in determining the jurisdictions to which tax is owed and to calculate appropriate sales and use tax rates for individual addresses.

Beginning July 1, 2021, all retailers will be required to apply the destination sourcing rules.  The Department does not have the authority to grant exceptions to these rules.

What is SUTS?

SUTS is the new Sales & Use Tax System from the Colorado Department of Revenue. The SUTS System is a one-stop portal that allows you to do all manner of tasks related to collecting and remitting sales and use tax in an easy, automated and seamless fashion. The system has the following capabilities:

  • Accurately look up sales and use tax rates by address
  • Single point of remittance and a uniform remittance form
  • Taxability and exemption matrix
  • Ability to calculate tax rates on items with differing tax rates in the same jurisdiction
  • A record of the history of any changes

Remittance Portal

The primary element of the SUTS System is the Remittance Portal. This portal allows you to file your retail sales tax returns for state, state-collected, and participating home-rule self-collecting taxation jurisdictions in one place.

Note: For special event sales tax, businesses should continue to use Revenue Online to e-file their special event sales tax returns (DR 0098). 

Geographic Information System (GIS)

Another element 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.
