DBA Filing in Colorado: Cost, Steps & How to File

DBA Filing in Colorado sits at the intersection of state, county, and city rules — which is why nobody gives you a single checklist. Below is that checklist, put together from the Colorado Secretary of State and Department of Revenue's own guidance, so you know what you're actually on the hook for before you start filing.

Timeline

1–30 days

Renewal

Every 5 years in most states (California, New York, Texas)

Who needs it

sole proprietors, partnerships, and LLCs operating under a name different from the legal registered name

Steps to file a DBA (fictitious business name) in Colorado

Step 1: Search the county's DBA database to confirm the name isn't already taken
Step 2: File a DBA / fictitious business name (FBN) statement at the county clerk's office
Step 3: Pay the county filing fee
Step 4: In some states (California, Georgia, others), publish the DBA in a local newspaper for 4 consecutive weeks
Step 5: Return the newspaper's proof of publication to the county
Step 6: Use the DBA on all business marketing, receipts, and bank accounts
