General Business License
Colorado does not have a statewide general business license requirement. Businesses must register their entity with the Colorado Secretary of State and obtain a sales tax license from the Colorado Department of Revenue if selling taxable goods or services. Many municipalities require a local business license — Denver, Aurora, Colorado Springs, and Boulder all have their own business licensing programs with state-set annual fees that vary by program.

Home-Based Business Rules
Colorado municipalities regulate home-based businesses through local zoning ordinances. Denver allows home occupations with restrictions on customer visits (typically 1 person at a time), no exterior display, and no storage of commercial vehicles. Colorado State law preempts local regulations that would completely prohibit home-based businesses. The Colorado Cottage Food Act specifically authorizes home-based food production with certain limitations.
