Colorado LLC Fees (2026): What the State Charges and the 3 Best LLC Services

If you are starting a limited liability company in Colorado in 2026, our recommendation is Mainstay Filing ($199), CO Registered Agent.org ($199) and Colorado Registered Agent.co ($199), in that order. Here is what the state itself will ask of you: $50 to file, then $25 every year for the periodic report. Across three years, that puts Colorado at 10th of 50 on state cost.

What we would pick in Colorado

Five weighted criteria set the order (see the method): three-year fees 33%, filings covered 26%, and then renewal terms, fit with Colorado rules and a clear state fee.

Our top choice

1. Mainstay Filing: best for one price for filing and ongoing upkeep

Year 1 is $199, later years $199, and the state fee is separate

Mainstay Filing ranks first for you since a $199 yearly price replaces three separate jobs: the Colorado formation, the registered agent and the periodic report.

Plan on spending $200 more than at CO Registered Agent.org over three years, in exchange for fewer filings left for you to do.

Each renewal includes the periodic report, and the $25 state fee is billed at cost.
