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 fees ranging from $25 to $500 annually.
