Vendors – Licensing and Taxes

All vendors are responsible for their own licensing and the collection and payment of taxes on all sales.

For more information and proper forms contact the Colorado Department of Revenue.

The current tax rate for items sold at the Mart is 4.75% (as of September 11, 2014). To verify this and obtain other tax information, please visit the Adams County Sales Tax site by clicking here. Denver Mart is located in Unincorporated Adams County, west of Box Elder Creek. Adams County has a phone number on that webpage so you can call if you need to.

The State of Colorado collects all taxes including taxes for Adams County. There is no city tax because the Mart is in unincorporated Adams county.

Please verify that these amounts have not changed.
