Step 2: Choose a Registered Agent
When starting an LLC in Connecticut, Choosing a registered agent is essential. This person will handle legal documents and state mail for your LLC. According to Connecticut LLC regulations, the agent must be a resident of Connecticut or an authorized business entity within the state. Although you can update the registered agent’s address later, choosing someone reliable is crucial. Many LLCs select one of their members as the registered agent for convenience.

Step 4: Create an Operating Agreement
