- Prepare the DBA filing. The Colorado Secretary of State requires the legal name of the owner, the DBA name, business address, and a description of business activities.
- Pay the $20 state fee and submit. File online with the Colorado Secretary of State or use File.Business to handle it for you at the state cost.

Start my Colorado DBADBA vs LLC in Colorado: which do you need?
A DBA is a name registration, not a business structure. It does not provide liability protection, separate tax treatment, or formal recognition as a business entity. If you want personal liability protection while operating under a brand name in Colorado, you typically form an LLC and then optionally file a DBA for additional brands.

Processing time with the Colorado Secretary of State varies. Online filings are typically processed within 2 to 5 business days. We submit the filing the same day you order.
How long is a Colorado DBA valid?
1 years from filing date. You must renew before expiration to keep the name registration active.
Do I need an EIN if I file a DBA in Colorado?
Only if you have employees, file certain tax forms, or open a business bank account in the DBA name. Sole proprietors with no employees can use their SSN. Get an EIN.

Does a Colorado DBA protect my brand from others using the same name?
A DBA only reserves the name with the Colorado Secretary of State. For broader brand protection, file a federal trademark with the USPTO.
