Starting a Business

Trade name registration

State law requires all businesses to register their “Trade Name(s)” within the local Town Municipality where the business is registered to do business, and file a Personal Property Declaration Form at the Office of the Tax Assessor.

A “Trade Name” Certificate form requires a filing fee of $5.50 per document.  If you have a name change, dissolve the business or relocate to another municipality, you must file another Trade Name Certificate.  In New Haven, the place to file is:

City of New Haven
City/Town Clerk’s Office
200 Orange St, room 202
New Haven, CT 06510
(203) 946-8346
