DBA registration

30 steps across 6 sections

1. When Is A Dba Needed?

  • Sole proprietors who want to operate under a business name rather than their personal name (e.g., "Jane Smith" doing business as "Jane's Bakery")
  • Partnerships operating under a name other than the partners' combined legal names
  • LLCs or corporations using a different name from their registered entity name (e.g., "Smith Holdings LLC" doing business as "Main Street Coffee")
  • Banks and financial institutions often require a DBA on file before opening a business bank account under the trade name
  • Multiple brands — a single LLC operating several distinct business lines may file separate DBAs for each

2. County Vs. State Filing

  • County-level filing: Some states (e.g., New York, California, Florida) require DBA registration at the county clerk's office in the county where the business operates
  • State-level filing: Other states (e.g., Colorado, Oregon) require filing with the Secretary of State
  • Both: A few states require filing at both levels
  • Multi-county/multi-state: If operating in multiple counties or states, you must file in each jurisdiction where you do business

3. Cost

  • Low end: Missouri ($7), Virginia ($10), Colorado ($20)
  • Mid range: Most states charge $20-$50
  • High end: Georgia ($150-$200), New York City area (higher due to publication requirements)
  • National average: Approximately $20-$50

4. Publication Requirements

  • New York: Must publish in two newspapers (one daily, one weekly) for six consecutive weeks in the county of filing. Publication costs can run $200-$1,000+ depending on the county (Manhattan is most expensive)
  • California: Must publish in a newspaper of general circulation in the county once a week for four consecutive weeks within 30 days of filing
  • Florida: Requires one-time publication in a local newspaper
  • Arizona, Nebraska, Pennsylvania: Also have publication requirements with varying terms

5. Renewal Period

  • Most states require renewal every 1 to 5 years
  • Common renewal periods: California (5 years), New York (no expiration but must refile if address changes), Florida (no expiration), Texas (10 years with assumed name certificates)
  • Failure to renew can result in the DBA lapsing, forcing you to refile from scratch and potentially losing the name to someone else
  • Some states send renewal reminders; many do not — track your own deadlines

6. Steps Process

  • Choose your DBA name — Pick a name that is not already in use in your jurisdiction
  • Search for name availability — Check your state/county database and the USPTO trademark database to avoid conflicts
  • Determine filing location — Identify whether your state requires county, state, or both filings
  • Complete the registration form — Provide your legal name, DBA name, business address, and type of business
  • Pay the filing fee — Fees range from $10 to $200 depending on jurisdiction
  • Publish if required — In states with publication requirements, arrange newspaper publication within the required timeframe
  • File proof of publication — If publication was required, file the affidavit of publication with the filing authority
  • Use the DBA — Open a bank account, sign contracts, and market under your new name
  • Set a renewal reminder — Calendar the renewal date so the DBA does not lapse

Common Mistakes

  • Assuming a DBA provides legal protection
  • Not searching for existing names
  • Forgetting publication requirements
  • Filing in only one jurisdiction
  • Letting the DBA lapse

Pro Tips

  • File the DBA before opening your bank account
  • Search the USPTO trademark database
  • Keep copies of all filings and publication affidavits
  • Consider an LLC instead
  • File early
