Colorado Business Licensing Requirements

Getting your Colorado sales tax license is just one step. Depending on your business type and location, you may need additional licenses and registrations. Here is an overview of common Colorado business requirements.

Secretary of State Registration

Most Colorado businesses must register with the Colorado Secretary of State. This includes:

• Limited Liability Companies (LLCs)
• Corporations (S-Corp, C-Corp)
• Limited Partnerships
• Trade Name Registrations (DBA)

Sole proprietors using their legal name do not need to register with the Secretary of State, but those using a business name should file a trade name statement.

Register online at sos.state.co.us or through mybiz.colorado.gov.

Federal Employer Identification Number (EIN)

If your business has employees, operates as a corporation or partnership, or files certain tax returns, you need an EIN from the IRS. This is also called a Federal Tax ID.

Apply free at irs.gov/ein. The process takes about 10 minutes online, and you receive your number immediately.

Local Business Licenses

Many Colorado cities and counties require a local business license. Requirements and fees vary by location. Check with:

• Your city clerk’s office
• Your county clerk and recorder

Major cities like Denver, Colorado Springs, Boulder, and Aurora have their own licensing requirements separate from state registration.

Professional Licenses

Certain professions require state licensure through the Colorado Department of Regulatory Agencies (DORA):

• Contractors (general, electrical, plumbing)
• Real estate agents and brokers
• Cosmetologists and barbers
• Accountants (CPAs)
• Architects and engineers
• Healthcare professionals

Verify requirements at dora.colorado.gov.

Industry-Specific Licenses

Depending on what you sell or do, additional permits may be required:

• Food Service: Colorado Department of Public Health and Environment license, plus local health department permits
• Liquor Sales: Colorado Liquor Enforcement Division license
• Cannabis: Marijuana Enforcement Division license (separate from retail)
• Motor Vehicle Dealers: Colorado Auto Industry Division license
• Childcare: Colorado Department of Human Services license
• Agriculture: Colorado Department of Agriculture permits

Home-Based Businesses

Colorado is relatively friendly to home-based businesses. However, you may still need:

• Local business license
• Home occupation permit (zoning compliance)
• Sales tax license (if selling taxable items)

Check your local zoning ordinances before operating from home, especially in HOA communities.

Periodic Report Requirements

Colorado LLCs and corporations must file a Periodic Report with the Secretary of State annually.

• Filing window: Your anniversary month through the end of the following month
• Fee: $10 online

Failure to file can result in administrative dissolution of your business entity.
