Denver
Do you need a business license in Denver?
Denver has no general business license; the city licenses a defined list of regulated activities through its Department of Excise and Licenses, and the registration most Denver businesses actually need is tax-side: a Denver sales tax license from the city's Department of Finance for retail sales, because Denver is a home-rule city that collects its own sales tax, alongside the Colorado state sales tax license.

No general license, a real licensed-activity list
Denver's Department of Excise and Licenses issues licenses for a defined list of regulated activities: retail food establishments, liquor and cannabis businesses, short-term rentals, security guards and firms, child care, body art, and dozens more. If your activity is not on the list, there is no general Denver business license to obtain. Contractor licensing is separate, running through the city's Community Planning and Development department with trade licenses and permits for the work itself.
The home-rule sales tax trap
Colorado is unusual: home-rule cities administer their own sales taxes independently of the state. A business making retail sales in Denver needs a Denver sales tax license from the city's Department of Finance and files Denver returns, in addition to the Colorado sales tax license from the state Department of Revenue. Businesses that assume the state license covers the city discover the gap at audit time, and the same pattern repeats in other Colorado home-rule cities.
The Colorado layer
Entities register with the Colorado Secretary of State, trade names file there as well, and the state sales tax license comes from the Colorado Department of Revenue for taxable sales. Regulated professions and industries license through the Department of Regulatory Agencies (DORA). Our Colorado business license page covers the state stack in full.
How to proceed
Check whether your activity appears on the Excise and Licenses list and apply with the city if it does, obtain the Denver sales tax license for retail sales alongside the state license, and clear zoning and building permits for any physical location. Cornerstone manages the Colorado and multi-state layer, entity work, state sales tax licensing, and DORA industry licenses, and flags the home-rule city registrations your footprint adds; the city licenses issue from Denver's departments to the operator.
The Colorado state layer
City requirements sit on top of Colorado's state-level rules: entity registration, tax permits, and industry licenses. Check both layers together.
Colorado business license requirementsFrequently asked questions
Does a home-based business in Denver need a license?
Only if the activity itself is licensed or the business makes retail sales. Home occupations operate under Denver's zoning rules, and a home-based retailer still needs both the Denver and Colorado sales tax licenses.
Is the Denver sales tax license the same as Colorado's?
No. Denver administers its own sales tax as a home-rule city, so the city license and returns are separate from the state's. Retailers in Denver hold both and file with both.
Do contractors need a Denver license?
Yes, contractors performing regulated work in Denver license through Community Planning and Development, with license classes by trade and permits pulled per project. State-level requirements, electrical and plumbing licensing through DORA, sit alongside the city's program.
