Geographic Information System (GIS)
The Geographic Information System(GIS) now allows Colorado taxpayers 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.
How to Use the Geographic Information System

See the Sales Tax Filing Information web page for more information.
