On Nov. 4, 2003, the electors of Arapahoe County voted to impose a 0.25% County Open Space sales and use tax on the sale of tangible personal property at retail and the furnishings of certain services within the County as provided in Section 29-2-105(1)(d), C.R.S. This tax is equal to 25 cents on every $100 spent. The tax is effective Jan. 1, 2004 through Dec. 31, 2023 for the purpose of preserving open space in Arapahoe County. 

This tax is to be remitted to the Colorado Department of Revenue on the same form that is currently used to remit state sales tax, Form DR 0100. Arapahoe County allows a vendor fee of 0.5% to cover the retailer’s expenses for collecting and remitting the sales tax as allowed by state law.

Please see the links below for more information on the Open Space sales and use tax. Businesses with questions can call 303-795-4620 or email finance@co.arapahoe.co.us.
