Connecticut Modernizes DBA Filing Requirements: What Businesses Need to Know

Changes introduced under Public Act 24-111 aim to standardize the way trade names—commonly known as DBAs (Doing Business As)—are registered and maintained in Connecticut. While the updates mark a shift toward more centralized and modern processes, they also introduce new filing requirements that businesses must be prepared to meet.

New Expiration and Renewal Requirements

One of the most notable changes is the introduction of a five-year expiration period for all trade names filed on or after January 1, 2025. Under the previous rules, trade names in Connecticut did not expire, which made long-term recordkeeping inconsistent across towns. With the new law in place, trade names will now automatically expire five years after the date of registration unless actively renewed.

For businesses that filed trade names before January 1, 2025, the state has provided a transition period. These existing registrations will remain valid until December 31, 2029, after which they must be renewed to remain active. This update adds a new layer of ongoing maintenance that businesses must track to avoid losing rights to their trade names.

Standardized Filing Location and Increased Fees

Previously, businesses operating in multiple towns within Connecticut were required to file trade names in each town. Public Act 24-111 simplifies this by requiring businesses to register their trade names only in the town where they are primarily operated. This reduces duplication and aligns with the state’s goal of improving the accuracy and accessibility of trade name records.

The updated law also introduces a fee increase from $10 to $20. While the increase is modest, it reflects the additional administrative oversight and upcoming system improvements the state is making.

Out-of-state businesses with a physical location or office in Connecticut will now need to register their trade name in the town where that location exists. If the business has multiple offices in Connecticut, it must select one as its principal location and register there. For businesses without a physical presence in the state, trade name registration should be completed in the town where the company’s registered agent is located.
