All persons engaged in business in the City are required to have a City Sales and Use Tax Business License. There are three types of business licenses. The paperwork required for each license varies by business type.
Types of Licenses and Forms
Please complete and send the appropriate form to...

There is no fee for any of the licenses, and no annual renewal requirement. However, commercial businesses must obtain a certificate of occupancy inspection prior to opening. The paperwork for this certificate is included with the licensing forms, and there is a $25.00 fee required at the time the application is submitted.
If you have questions about a building permit or a certificate of occupancy you may contact the Building Department at 303-538-7250 or visit their web page at Building Permits Home.
If your business discontinues operations in Thornton for any reason, please notify the Revenue Division in writing that you would like to cancel your license.
Special Case Businesses
Additional paperwork or licensing may be required for certain businesses such as those selling liquor, pawn brokers, and massage therapists. Please contact the City Clerk’s office at 303-538-7230 or visit the City Clerk Page to see if additional paperwork is required for your type of business.
