You need a DBA in Connecticut when your business operates under a name different from its legal name. Common cases:
- A sole proprietor in Connecticut doing business under a brand name instead of their legal name

How to file a DBA in Connecticut: 5 steps
- Choose your DBA name. Search the Connecticut business name database to confirm the name is available. It must not be deceptively similar to existing registered names.
- Verify name compliance. Connecticut prohibits names that imply a corporation (Inc., Corp.) unless your entity actually is one. Avoid restricted words.
- Prepare the DBA filing. The Town Clerk requires the legal name of the owner, the DBA name, business address, and a description of business activities.
- Pay the $10 state fee and submit. File online with the Town Clerk or use File.Business to handle it for you at the state cost.
- Track the 5-year renewal. Connecticut DBAs expire and require renewal. We track this for you automatically with our compliance calendar.

Start my Connecticut DBADBA vs LLC in Connecticut: 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 Connecticut, you typically form an LLC and then optionally file a DBA for additional brands.

Connecticut DBA frequently asked questions
How long does it take to file a DBA in Connecticut?
Processing time with the Town Clerk 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 Connecticut DBA valid?
5 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 Connecticut?
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.
Can I file a DBA in Connecticut for an out-of-state LLC?
Yes. If your LLC is registered in another state and does business in Connecticut, you typically need to foreign-qualify in Connecticut first, then file the DBA.
Does a Connecticut DBA protect my brand from others using the same name?
A DBA only reserves the name with the Town Clerk. For broader brand protection, file a federal trademark with the USPTO.
