What is a Connecticut registered agent?
A registered agent is a point of contact, either a person or company, that you select to receive important documents or tax notices on behalf of your company. This isn’t someone who merely collects your mail, this person will receive tax or government notifications and legal documents such as service of process should your business be sued. It’s an important role and one that every business owner should think about before setting up a company.

How does an owner select a registered agent in Connecticut?
To select a registered agent for your LLC, the person or company needs to be listed on the LLC formation documents that are filed with the Connecticut Secretary of State. This document is called the Certificate of Organization (sometimes referred to as Articles of Organization or Articles of Incorporation) and will require the registered agent’s name and agent’s address. Filing these forms will ensure this information is on public record with the Secretary of the State.
Can I be my own registered agent in Connecticut?
Yes. A business owner can be their own registered agent. Most entrepreneurs fill the role themselves, especially if they want to save money. However, you can select a friend, employee, or even a registered agent service to take on the responsibility.
Who can be a registered agent in Connecticut?
Regardless of whether a business owner chooses an individual or a business entity, a Connecticut registered agent must fulfill the following requirements:
- The agent must be an adult 18 years or older
- The agent’s street address (which will be used as the registered office) must be a physical address in Connecticut, not a P.O. box or virtual office
- Consistently be available during normal business hours on normal business days (Monday through Friday, 9 a.m. to 5 p.m.)
- If the agent is a business they must be in good standing with the state
- If the agent is an individual they must be a resident of Connecticut
Why would a company choose to work with a registered agent service?
A registered agent service is beneficial to many owners. If you don’t want to serve as your own registered agent or aren’t comfortable with someone else filling this role, a service is ideal. Additional benefits of a registered agent service include:
- Convenience. With a registered agent service in charge of accepting official documents, it’s more convenient. You don’t have to feel as though you’re tied to a desk and can go about your day as usual. Most services also provide an online account where you can easily and securely access any documents you might need at any time. A registered agent service provides a convenience factor for many entrepreneurs.
- Peace of mind. With a registered agent service, a business owner knows that nothing will be missed. All documents will be received by a trusted company that will contact you when something comes in. Many companies have same-day scanning and mail forwarding services that also help to provide peace of mind.
- Privacy. Some of the documents that a registered agent receives are best kept private. Service of process papers, for example, which is served when a company is sued, is something you’d probably like to keep confidential. To do so, a registered agent service should accept the paperwork at an off-site location.
- A registered office. Not every business owner is a Connecticut resident or has a physical address to list as their registered office, as some may be relocating or conducting business from another state. By using a registered agent service, you’ll be able to use the agent’s business address as your registered office to easily satisfy this state requirement.

A registered agent in Connecticut is a person or business entity designated to receive legal documents, tax notices, and official government correspondence on behalf of your LLC or corporation. Under Connecticut General Statutes § 34-243g, every business entity formed or registered in Connecticut must continuously maintain a registered agent with a physical street address in the state. The registered agent must be available during normal business hours to accept service of process — meaning lawsuit notifications, subpoenas, and other legal filings. You can serve as your own registered agent, appoint a trusted individual, or hire a professional registered agent service. Most Connecticut business owners choose a professional service for privacy, reliability, and compliance peace of mind.
No. If a business entity fails to maintain a registered agent or the agent cannot be found at the designated address, the state may serve legal documents through alternative means, and the business risks losing its good standing. Business owners can verify their registered agent status and file changes through the Connecticut Secretary of State website.
When selecting a registered agent in Connecticut, ensure the agent can reliably receive and forward time-sensitive legal documents. Missing a service of process notice could result in a default judgment against your business. Professional registered agent services provide consistent availability, privacy protection, and compliance monitoring that individual agents may not offer.
