How to Register for a DBA

File a DBA to operate under a business name different from your legal entity name — costs $10-$100 depending on jurisdiction.

1. Check if you need a DBA. You need a DBA if your operating name differs from your legal entity name. sole proprietors using anything other than their legal name need one. LLCs and corporations need one only if operating under a name not registered with the state.
2. Search name availability. Check your county clerk or state database for name conflicts. Most jurisdictions require your DBA name be distinguishable from existing registrations. Some states maintain online databases; others require in-person or phone inquiries.
3. File the registration. Submit your DBA application to the county clerk (most common) or state agency. Include your legal name, proposed DBA name, business address, and nature of business. Pay the filing fee, typically $10-$100.
4. Publish if required. Many jurisdictions require newspaper publication of your DBA filing. Publication periods range from one to four weeks in a local newspaper. Publication costs typically run $50-$200 depending on your area.
5. Update business accounts and contracts. Notify your bank to add the DBA name to business accounts. Update vendor contracts, customer agreements, and marketing materials. Keep your DBA certificate accessible for banking and contract verification.
6. Track renewal requirements. Most DBAs expire after 5 years, though some jurisdictions require renewal every 1-3 years. Mark your renewal date and budget for re-filing fees. Expired DBAs can trigger banking holds and contract issues.
