To be a vendor of tangible products at a special event (craft sales, etc.), you must obtain a special events permit from the State of Colorado, Department of Revenue. At an event held within the City limits of Fort Morgan, both City (3.0%) and State (2.9%) sales tax (total of 5.9%) must be charged to all customers and paid to the State of Colorado (Fort Morgan is a state-collected City).
The only permit or license required is the State of Colorado Special Events Permit. Also, the State has a special tax return form that must be used.
