Colorado Secretary of State (SOS)

State of Colorado Seal

In addition to complying with local, state, and federal regulations, businesses operating in Colorado are required to establish an entity name with the Secretary of State’s Office (SOS).  This includes establishing business names, such as d/b/a’s, fictitious names, and trade names along with the required submission of regular and ongoing reporting to the SOS.

With estimates of over 600,000 thousand businesses operating in Colorado, businesses are often targeted with government services schemes relating to the Secretary of State's requirements. 

One of the most prevalent scheme relates to deceptive mailers that appear similar to an official government document notifying businesses of the Periodic and Annual Reporting requirements in Colorado. 

Common Characteristics:

  • Almost exclusively originates via the mail.
  • Documents appear to originate from a government agency and/or references official agency executives and agency contact information;
  • Scheme references Periodic or Annual reporting requirements of the Secretary of State’s Office;
  • Costs associated with the reporting requirements generally exceed $200.00; and include
  • Veiled threats of high penalties and fees for not complying.   

The best way to avoid becoming a victim of this scam is to understand what the operating requirements are within Colorado and familiarize yourself with the associated fee structure.  Periodic reports cost as little as $10.00 to file.  The Secretary of State offers several resources and tips to help a business register and comply with reporting requirements. 

  • Always work directly with the Colorado Secretary of State’s Office.
  • Sign-up for the SOS’s email notification alert system.  As the SOS’s Office does not send mailing postcards, this system will alert you when your business must file a periodic report and will also notify you of any changes made to your business record.
  • Understand what forms are required by the Secretary of State.
