Every LLC in the United States is required by law to have a registered agent. That requirement shows up during formation - your state asks for a registered agent name and address when you file your Articles of Organization. But most first-time business owners are not sure what a registered agent actually does, whether they can fill the role themselves, or why it matters beyond checking a box. This guide answers all of it clearly.

What a Registered Agent Is
A registered agent is a person or company designated to receive official legal and government documents on behalf of your LLC. Every US state requires LLCs to maintain a registered agent with a physical street address in the state where the LLC is registered.
The registered agent's address is the official point of contact for your business in the eyes of the state. When the government sends a notice, or when someone files a lawsuit against your LLC, those documents go to your registered agent first. The agent then forwards them to you so you can respond in time.
Some states use slightly different terminology. Maryland, for example, calls this role a "resident agent" rather than a registered agent. New York uses "registered agent" but has its own specific service-of-process rules. The function is the same across all states: someone who can reliably receive official documents on your behalf during business hours.
What a Registered Agent Actually Does
The registered agent role sounds simple, but the practical responsibilities matter to the health of your LLC.
Receives service of process. This is the most important function. If your LLC is sued, the plaintiff's process server will deliver the lawsuit documents to your registered agent's address. Your registered agent receives them and forwards them to you immediately. Missing a lawsuit notice because your registered agent was unavailable or had the wrong address can cause you to lose the case by default, without ever having a chance to defend yourself.
Receives state and government notices. Tax notices, compliance warnings, annual report reminders, and correspondence from the Secretary of State all go to your registered agent. These documents often have deadlines. If they arrive late or are forwarded to an old address, you may miss critical filing windows.
Maintains a reliable physical address. Your registered agent must maintain a physical street address (not a PO Box) in the state where your LLC is registered and must be available there during normal business hours on every business day. This ensures there is always a real place for official documents to arrive.
Stays current with your information. A good registered agent service scans and emails received documents immediately so you get them no matter where you are. They do not hold documents or wait for you to check a mailbox.
Quick note on Maryland
Maryland calls this role a "resident agent," not a registered agent. The requirement is the same: a physical Maryland address, available during business hours. Maryland LLCs are filed through the State Department of Assessments and Taxation (SDAT), not the Secretary of State.
Who Can Be a Registered Agent
The requirements for who can serve as a registered agent vary slightly by state, but the basics are consistent across all 50 states.
The registered agent must be either an individual person or a business entity authorized to operate in the state. An individual must be 18 years or older and must have a physical street address in the state (a PO Box is not acceptable). A business entity can serve as a registered agent if it is registered to do business in that state.
The registered agent must be available at their listed address during normal business hours on every business day. This is not optional - state statutes specify availability as a requirement, and if a process server arrives and no one is there to receive documents, the state can consider your registered agent requirements unmet.
Can You Be Your Own Registered Agent?
Yes. In most states, you can serve as your own registered agent as long as you meet the requirements: you must be 18 or older, have a physical street address in the state where your LLC is registered, and be available at that address during normal business hours every business day.
If you live in the same state where your LLC is registered and work from home or an office with a physical address, you technically qualify. Many first-time LLC owners do this to save money on a registered agent service.
However, there are practical reasons why many business owners eventually move away from this arrangement.
- Your personal address becomes public record. Registered agent information is filed publicly with the state. If you list your home address, it appears in the state's business database and can be found by anyone doing a business search.
- You must be physically present. If you travel, work remotely, or simply step away from your office, there may be times when no one is available to receive documents at your address. Process servers document their attempts, and unavailability can create complications.
- You cannot use a PO Box. If you work from home and prefer not to list your home address publicly, a PO Box is not a valid alternative. It must be a physical street address.
- You cannot form an LLC in another state. If you want to register your LLC in Wyoming, Delaware, or any state where you do not live or have a physical address, you cannot serve as your own registered agent. You need a professional service with an address in that state.
Why Most Owners Use a Professional Registered Agent Service
A professional registered agent service solves every limitation listed above. For a small annual fee, a service provides a permanent physical address in any state you need, handles all incoming documents, and forwards them to you electronically the same day they arrive.
Your personal home address stays off public records. You can travel or work wherever you want without worrying about being available at a specific address during business hours. If you form LLCs in multiple states, one service can cover all of them. If you form an anonymous LLC for privacy purposes, a professional registered agent is an essential part of keeping your name out of public state databases.
Professional registered agent services typically cost between $49 and $299 per year. The cost is generally tax-deductible as a business expense. Brendat includes registered agent service in the Standard and Premium formation packages, so you do not need to set it up separately.

What Happens If You Don't Have a Registered Agent
Every state requires an active, valid registered agent for every LLC in good standing. Failing to maintain one has real consequences.
Your LLC falls out of good standing. States track whether registered agent requirements are met. If your agent resigns, moves, or becomes unreachable, and you do not update your registered agent with the state, your LLC can be flagged as out of compliance. Losing good standing means you cannot sign contracts, obtain financing, or open business accounts in some states until the status is corrected.
You may miss a lawsuit. If your registered agent cannot be reached and a process server cannot deliver lawsuit documents, the court may allow the case to proceed without you. A default judgment can be entered against your LLC, meaning the plaintiff wins simply because you were not notified in time to respond.
Your LLC can be administratively dissolved. If your LLC remains out of good standing for long enough, the state can dissolve it entirely. Reinstating a dissolved LLC typically costs more than the original formation fee and requires filing additional paperwork. In some states, the original LLC name may no longer be available after dissolution.
Staying current with registered agent requirements is one of the most basic parts of LLC annual compliance. It is not a formality to skip.
Registered Agent Requirements by State
The core requirement is the same in every state: a physical in-state address available during business hours. But there are some state-specific details worth knowing when forming an LLC outside your home state.
Wyoming. Wyoming does not require member names on Articles of Organization, making the registered agent especially important for privacy. The agent's address is public, but member names are not. This is one of the reasons Wyoming is a popular state for LLC formation by non-residents.
Delaware. Delaware has its own specific registered agent ecosystem. Because so many corporations and LLCs are formed in Delaware by out-of-state and international owners, there are many professional registered agent services specializing in Delaware. Delaware requires the agent to be either a Delaware resident or a business entity authorized to operate in Delaware.
Maryland. Maryland uses the term "resident agent" and requires the agent to have a Maryland address. LLCs are filed through the State Department of Assessments and Taxation, not the Secretary of State. If you are forming a Maryland LLC, make sure you use the correct terminology when searching for a service.
California. California requires the registered agent to be either a California resident or a registered corporate agent authorized by the California Secretary of State. The state maintains a list of approved corporate agents for this purpose.
New York. New York has a unique system for service of process. The New York Secretary of State is automatically designated as the agent for service of process for all LLCs registered in New York. However, you still need to provide a registered agent address for the state to forward documents to you.
Important
If you are forming an LLC in a state you do not live in, you cannot use a PO Box as your registered agent address. The agent must have a real physical street address in that state, open and staffed during business hours. Most professional services meet this requirement automatically.
How to Choose a Registered Agent Service
If you decide to use a professional service rather than serving as your own registered agent, here is what to look for.
Physical address in the state you need. Confirm the service has a real, staffed physical address in your LLC's state of registration. Ask specifically about the address - some services use shared mailroom addresses that may not meet state requirements.
Same-day document scanning and forwarding. When a lawsuit notice or compliance deadline arrives, time matters. Choose a service that scans documents and emails them to you on the same day they arrive, not weekly or on a batch schedule.
Multi-state coverage if needed. If you operate LLCs in more than one state, look for a service that can cover all of them from a single account so you do not juggle multiple vendors.
Transparent annual pricing. Some services advertise low first-year prices and then raise rates significantly at renewal. Confirm the ongoing annual fee before you sign up.
Compliance reminders included. A registered agent service that also sends you annual report reminders and compliance deadline alerts saves you from the administrative overhead of tracking multiple state deadlines on your own. You can also track state deadlines with the Brendat annual report tracker.
How to Change Your Registered Agent
If you need to change your registered agent because you hired a professional service, your current agent resigned, or your contact information changed, the process is straightforward but requires a formal state filing.
You file a Statement of Change of Registered Agent (the form name varies by state) with your state's Secretary of State or equivalent office. There is usually a small filing fee, typically between $25 and $50. The change takes effect when the state processes the filing, which can take a few days to a few weeks depending on the state.
Your new registered agent must consent to the appointment before you file. Professional services handle this consent documentation as part of their onboarding process. When you use Brendat to change your registered agent, the paperwork is handled for you.
Do not stop using your current registered agent until the change is officially processed and confirmed by the state. There is a window during the transition when documents could arrive at either address, and you want both covered until the state record is updated.
Frequently Asked Questions
What does a registered agent do?
A registered agent receives official government and legal mail on behalf of your LLC, including service of process (lawsuit notices), tax notices, and annual report reminders. They must be available at a physical in-state address during normal business hours every business day.
Can I be my own registered agent?
Yes, if you have a physical street address in the state where your LLC is registered and are available there during business hours. However, this means your personal address becomes public record and you must always be reachable at that address on business days. Most owners prefer a professional service for privacy and flexibility.
What happens if I don't have a registered agent?
Failing to maintain a registered agent puts your LLC out of good standing with the state, which can lead to loss of liability protection, inability to enter contracts, and eventual administrative dissolution. Lawsuit notices may also go undelivered, causing you to lose a case by default.
How much does a registered agent cost?
Professional registered agent services typically range from $49 to $299 per year depending on the provider and features included. Brendat includes registered agent service in the Standard and Premium LLC formation plans.
Can a registered agent be in a different state than where I live?
Yes. The registered agent must have a physical address in the state where your LLC is registered, not where you personally live. If you form an LLC in Wyoming but live in Texas, you need a Wyoming registered agent. This is one reason professional services are widely used by out-of-state and international LLC owners.
