What Is a Registered Agent?

A registered agent is the person or company an LLC names on its public record to receive lawsuits and official state mail at a street address in the state where the company is registered, during business hours. Every state but a couple requires one, the role goes by four different names, and the company that has none can lose a lawsuit it never heard about.

That is the whole definition. The rest of this guide is what the agent actually receives, why the states care so much about the address, who is allowed to do the job, whether you should do it yourself, and what the states do to a company that lets the role lapse.

What a registered agent receives

The agent exists so that there is always one place where the company can be reached by people who have a legal right to reach it. Three kinds of paper arrive there.

• Service of process. When the LLC is sued, the summons and complaint are handed to the agent. In most states the deadline to answer, often 20 or 30 days, runs from that moment whether or not the owner ever sees the papers. An agent who is not at the address, or who sits on the envelope, can hand the plaintiff a default judgment.
• Official state mail. The Secretary of State (or the state's equivalent) writes to the agent about the company's record: confirmations, corrections, the reminder that the annual or biennial report is due, the late notice after it was not filed, and the warning that administrative dissolution is coming.
• Other legal notices. Subpoenas for records, garnishment orders, tax notices in some states, and anything else a court or agency is required to deliver to the company's address of record.

Notice what is not on the list: customer mail, bank statements, packages. A registered agent is not a mailing address or a virtual office, and most agent agreements say so. Some agents forward ordinary mail for a fee, but the legal role is narrow by design.

Statutory agent, resident agent, agent for service of process

The role is the same everywhere; the word is not. Each state's LLC statute names the agent, and the state's forms follow the statute. If you form in Arizona you will be asked for a statutory agent, in Michigan for a resident agent, in California for an agent for service of process. Searching for "registered agent" on those states' sites can leave you thinking the requirement does not exist. It does.

The statute's own term was read on the official page for 51 of 51 jurisdictions in November 2026; a state whose statute we have not yet read is listed under "registered agent", the term its forms use. California, Nebraska, New Jersey, South Carolina, Vermont and West Virginia say agent for service of process; Minnesota and Pennsylvania say registered office; Kansas, Maryland, Massachusetts, Michigan and Rhode Island say resident agent; Arizona and Ohio say statutory agent.

A few states add a wrinkle. Minnesota and Pennsylvania require a registered office, a street address in the state for legal papers, and make naming an agent at that office optional; an agent or a commercial provider at that address does the same job, and the states' own forms still say registered agent. New York designates the Secretary of State as the agent for every LLC and makes a separate registered agent optional, so a New York LLC lists a mailing address to which the state forwards process instead. West Virginia's formation form makes the agent optional too. Everywhere else the agent is mandatory from the day the company is formed, whatever the statute calls it; where a statute's word differs from the state's own forms (New Jersey's statute says agent for service of process, its forms say registered agent), the state page says so.

Who can be a registered agent

The requirements are nearly identical across the country, because they all serve the same purpose: a process server has to be able to walk up to a door and hand papers to a person.

• A street address in the state. Not a PO box, not a mail drop, not a virtual office. Several states say in the statute that the registered office must be the agent's business address, and most reject a filing that lists a box number.
• Present in business hours. The agent, or someone at the agent's office, has to be there to accept delivery during normal business hours. A home address qualifies only if someone is reliably home.
• An adult resident of the state, or a company authorized there. An individual agent must live in the state (a few states say "resident" and mean it) and be at least 18. A business may serve if it is registered to do business in the state; several states also keep a list of commercial registered agents that have filed a listing statement.
• Not the LLC itself. Most states bar a company from being its own agent. A member or manager can serve as an individual, but the LLC cannot name itself. Kansas is the exception in our research: it lets the entity serve as its own resident agent.
• Consent. The agent must have agreed to serve. 13 jurisdictions put that consent on the formation filing itself, as a signature or an affirmation (Arizona, Colorado, Connecticut, Florida, Kentucky, Louisiana, Maryland, Massachusetts, Nevada, New Mexico, Ohio, Washington and Wyoming); the rest expect the company to hold the agent's consent in its records.

The state-by-state version of those rules, with who may serve and whether the agent signs in each state, is the 51-row table at registered agent requirements by state. Of the 51 jurisdictions, 49 require an agent on the formation filing and 2 (New York and West Virginia) do not.

Being your own agent or hiring one

Any owner who lives in the formation state and keeps regular hours at one address can be the agent for free, and many do. The decision turns on two things the free option gives up: privacy and availability.

Being your own agent works well for an owner who forms in the state they live in, works from a fixed commercial address with regular hours, and does not mind that address being public. It works badly for an owner who works from home, travels, forms in another state, or plans to move. The second group is who registered agent companies exist for.

A middle path some owners take is naming a trusted person: a spouse, an accountant, a lawyer with an office in the state. That is allowed everywhere, but the person is taking on a legal duty, and if they move or retire the company has to file a change just as it would for a commercial agent.

Do you need a registered agent in every state?

You need one in every state where the company is registered, not just where it was formed. An LLC formed in Wyoming that does business in Colorado must register in Colorado as a foreign LLC, and Colorado will ask for a Colorado registered agent on that registration. The home-state agent cannot cover a second state, because the point of the rule is a physical address inside the state's borders.

This is one of the hidden costs of forming out of state. Two registrations mean two agents, two annual reports, and two sets of state fees. The guide on whether you need a registered agent walks through when the home-state choice is the cheaper one.

What happens without a registered agent

A company has no agent when it never named one where it should have, when the agent resigned and nobody replaced them, or when the agent moved and the address on the record went stale. The consequences arrive in roughly this order.

1. Papers are served another way. Most statutes say that when the agent cannot be found with reasonable diligence, process may be served on the Secretary of State, or by mail to the company's last known address, and that service counts. The lawsuit proceeds whether or not the owner opens the mail.
2. Default judgment. A company that does not answer a complaint loses by default. Setting a default aside later is possible but expensive, and courts are not sympathetic to a company that failed to keep the one address the law required.
3. Loss of good standing. The state's notices about reports and fees go to the stale address too, so the report is missed, late fees accrue, and the company falls out of good standing. Banks and counterparties check that status.
4. Administrative dissolution or revocation. Failing to maintain an agent is a stated ground for administrative dissolution in most LLC acts, usually after a notice period of 60 days or so. Reinstatement means a new agent, every missed report, and a reinstatement fee.

Where the state's own page or statute spells out the consequence, we quote it below; 44 of 51 jurisdictions were read in November 2026. A state that is not listed has the same general rules; its specific language was not yet confirmed on an official page, and the state page says so.

What a registered agent costs

The state charges nothing for the agent itself. Naming one is part of the formation filing, and naming yourself costs nothing beyond the filing fee you already pay. The state charges only when you change agents later: among the 49 jurisdictions whose change-of-agent fee we read on an official page, 9 charge nothing (Arkansas, Idaho, Indiana, Iowa, Massachusetts, Montana, Oregon, Virginia and Washington) and the rest charge $5 to $100. A few states let the annual report name the new agent at no extra charge.

A commercial agent charges a yearly fee for the address, the staffed hours and the forwarding. The fee buys three things the free option cannot: an address that is not yours on the public record, someone always present to accept papers, and the same arrangement in any state where you register. Ours is listed in the application with its price on the review screen, and an LLC that already exists can switch to our agent at any time. If you form through our sister site, you can add the agent while you form on America LLC Filing.

When you compare agents, read past the first-year price. Ask what the renewal costs, how documents are delivered (same-day scan or paper mail), whether cancelling is a click or a phone call, and whether the agent files the change-of-agent form for you when you switch.

How to change your registered agent

Changing agents is one state filing, usually called a statement of change of registered agent, with a modest fee or none, and in some states it can be done on the annual report. The new agent must consent, the old one stays on the record until the state accepts the change, and the company's other registrations (IRS, bank, licenses) should be updated if they used the old address. The 51-state table of forms, fees and portals is in How to change your LLC's registered agent.

For your own state's rules in one place, including who may serve, whether the agent signs the filing, what becomes public and the change-of-agent form, open the state page: for example Texas, California, Florida, New York or Wyoming, or pick any state from the full list.
