What is a Registered Agent? Every state requires one.

A Registered Agent is the official point of contact between a US business entity and the state where it is registered. Every LLC, Corporation, and similar entity must designate a Registered Agent with a physical address in the state, available during business hours to accept legal notices and state correspondence.

Formal Definition

A Registered Agent (also called Resident Agent in Michigan and a few other states, Statutory Agent in Arizona and Ohio, or Agent for Service of Process in California) is a person or company designated to accept legal notices and official state correspondence on behalf of a business entity.

In plain English

Here is what that actually means.

The role exists for a simple reason: when a court, state agency, or other party needs to deliver formal documents to a business (a lawsuit, a tax notice, an annual report reminder), they need to know where to deliver them. The Registered Agent address is that delivery point, and it is on the public state record.

The Registered Agent does not run the business, does not have management authority, and does not control money. The role is purely administrative: receive documents during business hours, forward them to the business owner promptly. That is it.

Every state requires every LLC and Corporation to designate a Registered Agent in the state of formation. If you foreign-qualify in additional states (operate in states beyond your home state), you also need a Registered Agent in each of those states. Failing to maintain a Registered Agent can result in state-imposed dissolution.

How it compares

Related concepts side by side.

Registered Agent vs Owner
The Registered Agent receives documents. The owner runs the business. They can be the same person (if owner has a physical state address and is available during business hours), but they serve different functions.
Registered Agent vs Office Address
The Registered Agent address is for legal service. The principal office address is where the business actually operates. They can be different addresses.
Registered Agent vs Statutory Agent
Different names for the same role. Arizona and Ohio call it "Statutory Agent." Michigan calls it "Resident Agent." California calls it "Agent for Service of Process." Same function.
FAQ

Common questions.

What is a registered agent?
A registered agent is the person or company you designate to receive legal documents and official state mail on your business's behalf, and every state requires each LLC and corporation to have one with a physical in-state address. Without a valid agent, the state can refuse filings or revoke your standing. We serve as your agent and keep the record current.
Can I be my own registered agent?
Yes, if you have a physical address in the state and are available during business hours, but your address becomes public and you risk missing a lawsuit if you are out. Most owners use a service for privacy and reliability. We can take the role so the business is not tied to your availability.
What does a registered agent do?
It receives service of process, lawsuits and subpoenas, plus official state mail like annual report reminders and tax notices, and forwards them to you promptly. Timely forwarding matters because a missed lawsuit can lead to a default judgment. We scan and forward your documents the same day.
Why does the state require a registered agent?
So there is always a reliable, public point of contact to receive legal and government notices during business hours, which protects both you and anyone who needs to reach the company. A business without a valid agent loses that reliability and its good standing. We provide dependable coverage so nothing is missed.
What happens if my agent resigns or lapses?
It is a common cause of losing good standing: with no valid agent on record, the state stops reaching you and can move the entity toward administrative dissolution. You must name a replacement promptly. We provide continuous service and update the state record so there is never a gap. See changing agents.
Does the agent's address show publicly?
Yes: the agent's name and address are part of the public filing, which is why owners who use their home address lose privacy. A commercial agent's address appears instead of yours. We provide a business address for the role so your personal address stays off the public record.
Can one agent cover multiple states?
Each state requires an agent physically located there, so an entity registered in several states needs coverage in each, which a national provider handles under one account. We coordinate agent service everywhere you are registered, including any foreign registrations.
Do I need an agent before I file?
Yes: you must name the agent on the formation document, so it has to be lined up before you file with the state, or the filing is rejected. We put the agent in place as part of forming or registering your entity so the filing goes through the first time.
Does File.Business provide registered agent service?
Yes: we act as your registered agent in any state, keep the state record current, scan and forward service of process and state mail the same day, and track the deadlines those notices carry, so the role is handled reliably.
