Who needs a statement of trade name (DBA) in Colorado?

Issued by Colorado Secretary of State, at step 1 of 6 in the opening sequence: set up the business.

Every kind of business in Colorado

The Colorado table lists this for every kind of business.

Needed whenever the business trades under any name other than the owner’s legal name or the LLC’s registered name; an LLC and a sole proprietor both file with the Secretary of State, not the county. File it before the sales tax license, which asks for the trade name.
