Registered agent: what they do, who needs one
A registered agent (RA) is a legal designation: the person or company authorized to receive lawsuits, government notices, and tax correspondence on the LLC's behalf. Every state requires one. Every state requires the RA to have a physical street address in the state of formation. The role sounds bureaucratic, but it sits at the center of two things every LLC owner cares about: staying in good standing with the state, and keeping a home address off the public internet. This guide explains what a registered agent does, the legal requirements an agent has to meet, the trade-offs between serving as your own agent and hiring a service, and what happens when an LLC lets the role lapse.
What a registered agent actually is
A registered agent, sometimes called a statutory agent (Arizona, Ohio) or a resident agent (Maryland, Michigan, Nevada), is the official point of contact between an LLC and the outside legal world. When someone sues the company, a court mails a notice, or the Secretary of State sends an annual-report reminder, those documents go to the registered agent's address on file. The agent then forwards them to the people who run the LLC.
The role is narrow on purpose. A registered agent is not a manager, an accountant, a lawyer, or a decision-maker. Designating an agent does not give that person or company any authority over the business, its money, or its filings. The agent exists for one reason: to guarantee that the state and the courts always have a reliable, monitored address where official mail can be delivered and legally considered "received."
The three jobs of a registered agent
- Accept service of process. When an LLC is sued, a process server hand-delivers the complaint and summons to the registered agent. This is the single most consequential function. Legal deadlines start running from the moment those documents are served, whether or not the owner has seen them yet.
- Receive state and tax correspondence. Annual-report reminders, franchise-tax notices, and other official mail from the Secretary of State and the state revenue department are routed to the agent.
- Forward everything promptly. The agent passes documents to the LLC's owners or managers; national services typically scan and email the same day they receive an item.
That is the entire job. A registered agent does not file taxes, submit annual reports, or run any part of the business unless the owner separately pays for those add-on services.
Why every state legally requires one
An LLC cannot be formed or kept active without a registered agent on file. The Articles of Organization, the document that creates the LLC, must name a registered agent and list a valid in-state address before the state will approve the filing. There is no opt-out and no exception; the requirement applies to single-member LLCs run from a kitchen table the same way it applies to multi-state operating companies.
The legal logic is straightforward. A limited liability company is a separate legal "person" that can sue and be sued, but a company has no body to hand a lawsuit to. The registered agent solves that problem by giving the company a fixed, accountable human (or company) at a known address. It guarantees due process: a plaintiff always has a legitimate place to serve papers, and the courts can trust that the LLC was properly notified. Because the requirement is ongoing, not just at formation, an LLC must keep a valid agent on file for its entire life. Letting the role lapse is treated the same as abandoning the company's address.
What a registered agent must meet
Every state imposes the same core requirements, with minor wording differences:
- A physical street address in the state of formation. The address must be a real location where someone can physically receive hand-delivered documents. PO boxes do not qualify, and mailbox-rental storefronts (UPS Store, FedEx Office) generally do not either, because no one is stationed there to accept legal service.
- Availability during normal business hours. The agent has to be reachable at that address during standard weekday business hours so a process server can deliver papers in person.
- Consent to the role. An agent, whether an individual or a company, must agree to serve. A business cannot name a random person or address without permission; many states require the agent to sign or otherwise acknowledge acceptance.
- Eligibility. The agent must be an individual at least 18 years old who resides in the state, or a company authorized to do business there. The LLC can name a member, a manager, or a commercial service, but it generally cannot list itself as its own agent.
Option A: be your own registered agent
Any owner who has a physical address in the state of formation can serve as the LLC's own registered agent. The headline appeal is cost: it is free, with no annual service fee. For a local business operated from a fixed commercial address with predictable weekday hours, naming yourself can be a reasonable choice.
The trade-offs are real, though, and they are mostly about privacy and presence:
- The address becomes public record. The registered-agent address is published in the state's online business registry, where customers, competitors, marketers, or strangers can look it up. For a home-based business, that means listing a home address on the public internet.
- Lawsuits arrive in person. Service of process is delivered face-to-face. An owner serving as their own agent can be handed a lawsuit at home or in front of customers and staff, with no buffer.
- Physical presence is mandatory. The agent has to be at the listed address during business hours. That is a poor fit for owners who travel, work remotely, keep irregular hours, or run a business with no fixed storefront.
- Moving creates compliance work. Every time the address changes, the LLC has to file an updated registered-agent address with the state — an easy step to forget.
In short, being your own agent saves money but spends privacy and flexibility. Owners who value either tend to outgrow the DIY approach quickly.
Option B: a commercial registered agent service
A commercial registered agent is a company that serves as the agent of record for a yearly fee, typically $35 to $300 depending on the provider and state. The service maintains a staffed street address in the state, accepts documents on the LLC's behalf, and forwards them, usually by scanning and emailing the same day.
What that fee buys:
- Privacy. The service's address appears in the public registry instead of the owner's home or office. This is the main reason home-based founders pay for an agent.
- Reliable, professional handling. A staffed office never misses a delivery because someone was on vacation, in a meeting, or out sick. That eliminates the risk of an unreceived lawsuit.
- Mail forwarding and document scanning. Most providers digitize incoming mail and route it through an online dashboard, so documents are accessible from anywhere.
- Compliance reminders. Many services track annual-report and franchise-tax deadlines and send reminders, which reduces the chance of a missed filing.
- Multi-state coverage. National providers act as agent in all 50 states under one account, which is essential for any LLC that registers as a foreign LLC in additional states.
On pricing, the market splits into rough tiers: small boutique services at $35–$50; national mid-tier providers around $100–$150 (Northwest is widely known for a privacy-by-default model at about $125/year, Bizee around $119); and premium providers at $199–$299 (ZenBusiness around $199, LegalZoom around $249). For most LLCs, the $100–$150 tier covers everything needed without overpaying for the premium label.
Be your own agent vs. a commercial service
| Factor | Be your own RA | Commercial RA service |
|---|---|---|
| Annual cost | $0 | ~$35–$300/year |
| Privacy | Your address is public record | Their address is public, yours stays off the registry |
| Availability requirement | You must be present during business hours | Staffed office handles it for you |
| Multi-state coverage | Only states where you have an address | All 50 states under one account |
| Lawsuit delivery | Served to you in person, possibly publicly | Received discreetly, then forwarded |
| Best for | Local, fixed-address businesses on a tight budget | Home-based, remote, traveling, privacy-focused, or multi-state owners |
What happens if an LLC lets the role lapse
Failing to maintain a registered agent, or missing a service of process because no one was at the listed address, carries escalating consequences:
- Default judgments. If an LLC is sued and the lawsuit is delivered to a stale or unstaffed agent address, the owner may never see it. The case can proceed without the company's knowledge, and a court can enter a default judgment: the LLC loses automatically and may owe money before anyone realizes a lawsuit existed.
- Loss of good standing. When the state cannot reach the LLC because the agent moved, resigned, or stopped responding, the company is flagged as "Not in Good Standing." That status can block financing, contracts, and the ability to expand into other states.
- Administrative dissolution. If the lapse continues, the state can administratively dissolve the LLC, legally shutting it down. Reinstatement is usually possible but requires paying back fees, penalties, and a reinstatement filing fee, and the liability shield may be compromised for the period the company was dissolved.
The registered-agent requirement is one of the easiest ongoing obligations to overlook and one of the most expensive to ignore.
How to change your registered agent
Switching agents is routine and intentionally simple. The LLC files a change-of-agent form (commonly titled a Statement of Change of Registered Agent) with the Secretary of State, naming the new agent and address. Many states charge a small fee, and several charge nothing at all.
The most common reasons to change are switching from a DIY arrangement to a commercial service (or between services), an owner moving out of state, or a current agent resigning. When an agent resigns, the LLC typically has a statutory window (often 30 to 60 days, depending on the state) to name a replacement before good-standing problems begin. Filing the change quickly keeps the company compliant and prevents any gap in coverage.
The privacy angle: keeping an owner's name off public record
For owners who care about anonymity, the registered agent is only half the privacy equation. The other half is how the state handles member and manager names on the public filing. A handful of states, notably Wyoming, New Mexico, and Nevada, do not require the LLC to list its members on the public formation document. Combining one of those states with a commercial registered agent keeps both the owner's name and home address off the public record: the agent's address shows up in the registry, and no member name is published at all.
This is the core mechanism behind so-called "anonymous LLCs." It is worth being precise about what it does and does not do: it keeps ownership out of the casual public record, but it does not hide ownership from the IRS, banks, or courts that have legal authority to compel disclosure. For founders weighing where to form, the interaction between agent privacy and state disclosure rules is covered in depth in the best states to form an LLC guide.
Where the registered-agent cost fits
A registered agent is one recurring line item in the total cost of running an LLC, alongside the state filing fee, annual report fees, and any franchise taxes. Owners who serve as their own agent pay nothing for the role; those who hire a service add roughly $35–$300 a year.

Frequently asked questions
Can I be my own registered agent?
Yes, in your home state. The legal requirement is a physical street address in the state of LLC formation, available during business hours to receive legal mail and tax notices. A residential address qualifies. The trade-off is privacy and convenience: the address becomes part of the LLC's public record, and the LLC owner must be physically present at the address to receive service of process during business hours. Many home-based LLC owners hire a registered agent service specifically to avoid having a home address on the LLC's public filing.
Do I need a registered agent in every state where my LLC does business?
Every state where the LLC is registered — whether as a domestic LLC in its state of formation or as a foreign LLC in another state where it has foreign-qualified — requires a registered agent. An LLC operating in five states needs five registered agents if it is registered in all five. National registered agent services (Northwest, ZenBusiness, LegalZoom) cover all 50 states with a single account, which simplifies multi-state compliance and consolidates billing.
What happens if my registered agent moves or quits?
The LLC has a statutory window — typically 30 to 60 days depending on the state — to designate a replacement registered agent and file a Statement of Change of Registered Agent with the Secretary of State. Failure to maintain a registered agent results in the LLC being marked as 'Not in Good Standing' and eventually being administratively dissolved by the state. Reinstating an administratively dissolved LLC is possible but requires paying back-fees, penalties, and the reinstatement filing fee.
How much should I pay for a registered agent service?
The market range is $35 to $300 per year nationally. The cheapest tier ($35 to $50) is small boutique RA services with limited features. The mid-tier ($100 to $150) is national providers like Northwest ($125) and Bizee ($119) with online dashboards, document scanning, and compliance reminders. The premium tier ($199 to $299) is ZenBusiness ($199) and LegalZoom ($249), with renewal pricing that exceeds boutique options. For most LLCs, $100 to $150 buys adequate service without overpaying.
Can I use a PO Box as my registered agent address?
No. Every state requires the registered agent address to be a physical street address — usually called a 'street address' or 'physical street address' on the filing form to distinguish from a PO Box. The legal reason: the registered agent must be available to accept service of process in person, and a PO Box cannot accept hand-delivered legal documents. Mailing-service businesses (UPS Store, FedEx Office) that provide street-addressed mailbox rentals do not satisfy the requirement either, because no person is available to accept legal mail at those locations.
What does a registered agent actually do?
Three functions. First, accept service of process — the legal document a process server delivers when the LLC is sued. Second, receive tax notices and other official correspondence from the Secretary of State and state revenue agency. Third, forward those documents to the LLC owner promptly (national services typically scan and email same-day). The registered agent is not a manager, decision-maker, or representative — purely a point of contact for legally required deliveries.
