Online Tax Filing System

Commerce City uses an online tax filing system called MUNIRevs. With this system, the city no longer provides paper tax forms or booklets. The city requests that your business register for and take advantage of the online filing process.

The online filing portal allows businesses to create a free account that enables them to directly file and pay:

  • Sales and use taxes
  • Accommodations taxes
  • Marijuana sales and excise taxes
  • Public Improvement Fees (PIF)
  • Telephone utility occupation taxes  

Payments are processed through the Colorado Statewide Internet Portal Authority (SIPA), ensuring a very high level of security. There is a $1 per payment processing fee for e-checks, which is less than the total cost of printing and mailing the tax return and a check. Payment can also be made by credit card, however, there is a 75 cents surcharge and a 2.25% fee.

Please Note:

  • Before you file your taxes, please visit the Business License page to review license requirements based on the location of your business.
  • Commerce City does not require annual renewal of the general sales and use tax business license.
