Please remember that you must claim the state sales tax refund (TABOR refund) when filing your state income tax return. If you claimed a 2023 refund, the TABOR refund will be combined and issued out with your refund. Unlike the 2022 Colorado cashback, no separate check will be issued.

Select a tab title below to learn how to look up sales and use tax rates as well as location (jurisdiction) codes.


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.

You may e-file for multiple locations using approved XML software or request to file by spreadsheet, both of which are uploaded in Revenue Online. See the Sales Tax Filing Information web page for more information.

  • DR 1002 Document: This document lists the sales and use tax rates for all Colorado cities, counties, and special districts.
