How to Apply for a Colorado Sales Tax License

The Colorado sales tax license (in other parts of the country, may be called a reseller's license, a vendor's license or a resale certificate) is for state and state-administered sales and use taxes. Sometimes taxpayers refer to this as a business registration, but it is an application for a Colorado sales tax account or sales tax license. Most Colorado sales tax license types are valid for a two-year period and expire at the end of each odd-numbered year.

In Colorado, services are not subject to sales tax. In general, tangible personal property is subject to sales and use taxes in Colorado. For reference, see ยง39-26-102(15)(a)(I) C.R.S.

Please Note: These licenses will only cover state and state-collected tax jurisdictions. If you are in a home-rule (home rule) city, contact that city for their license requirements. Find out which cities are home-rule.
