Per Colorado Revised Statutes (C.R.S.) §43-4-218, Colorado imposes a retail delivery fee on deliveries by motor vehicle to a location in Colorado with at least one item of tangible personal property subject to state sales or use tax.

The retailer or marketplace facilitator that collects the sales or use tax on the tangible personal property sold and delivered, including delivery by a third party, is liable to remit the retail delivery fee. Deliveries include when any taxable goods are mailed, shipped, or otherwise delivered by motor vehicle to a purchaser in Colorado.
