Registered Agent for an LLC: Requirements, Cost & How to Choose (2026)

A registered agent is a person or business entity designated to receive official legal documents, tax notices, and service of process on behalf of your LLC. Every state requires LLCs to maintain a registered agent with a physical street address in the state of formation. This ensures government agencies and courts can reliably contact your business, and failure to maintain a registered agent can result in administrative dissolution, missed lawsuit deadlines, or loss of good standing.

What it is

A registered agent (also called a statutory agent, resident agent, or agent for service of process) is legally required under state LLC statutes to accept service of process—meaning lawsuits, subpoenas, and other legal papers—as well as correspondence from the Secretary of State and state tax authorities. The agent must have a physical street address in the state where your LLC is registered; P.O. boxes are not permitted. Most states allow you to serve as your own registered agent if you meet residency and availability requirements, or you can hire a commercial registered agent service.

The registered agent's name and address appear on your public formation documents and annual reports, making them visible in state business registries. If your LLC operates in multiple states (foreign qualification), you must appoint a separate registered agent in each jurisdiction. Registered agents must be available during normal business hours to accept documents, and they are responsible for promptly forwarding any correspondence to the LLC's principal office.

State variations

New York (NY): New York does not use the term 'registered agent'; instead, LLCs must designate the Secretary of State as the agent for service of process and provide a separate address where the Secretary will forward documents. This address must be maintained current with the Department of State.
California (CA): California requires the agent for service of process to be either a California resident, a California corporation, or an out-of-state corporation registered with the California Secretary of State. The agent's address is publicly listed on Form LLC-1 and Statement of Information (Form LLC-12).
Nevada (NV): Nevada mandates both a registered agent and a separate list of commercial registered agents maintained by the Secretary of State. The agent must have a Nevada street address and consent in writing (Form and Acceptance of Appointment) filed with the Articles of Organization.

Common mistakes to avoid

Using a P.O. box as the registered agent address. State statutes require a physical street address where process servers can deliver documents in person. Listing a P.O. box will cause your filing to be rejected by the Secretary of State.
Serving as your own agent without understanding availability requirements. If you designate yourself, you must be present at the registered address during business hours every weekday. Missing service of a lawsuit can result in a default judgment against your LLC.
Failing to update the registered agent when moving or changing services. If your agent relocates or you switch providers, you must file an amendment with the state. Outdated information can lead to missed legal notices and administrative dissolution.
Assuming one agent covers all states. Each state where your LLC is registered or qualified to do business requires its own in-state registered agent. Operating without a compliant agent in a foreign jurisdiction can void your authority to do business there.
Neglecting to notify the LLC when documents arrive. The registered agent's duty is to forward correspondence immediately. Delays in internal communication can cause missed court deadlines or lapses in compliance.

Frequently asked questions

Can I be my own registered agent for my LLC?

Yes, in most states you can serve as your own registered agent if you are a resident of the state and have a physical street address there. However, this means you must be available at that address during standard business hours every weekday to accept legal documents, and your home or business address will be part of the public record.

How much does a registered agent service cost?

Commercial registered agent services typically charge between $100 and $300 per year per state. Northwest Registered Agent, for example, offers annual plans starting around $125. Pricing varies based on service level, multi-state discounts, and whether mail forwarding or compliance reminders are included.

What happens if I don't have a registered agent?

Operating without a registered agent or failing to maintain a current agent on file violates state law and can result in the administrative dissolution of your LLC, loss of good standing, inability to defend lawsuits, and personal liability for members. Most Secretaries of State will send a notice of non-compliance before involuntary dissolution.

Do I need a different registered agent in each state where I do business?

Yes. If you qualify your LLC as a foreign entity in another state, that state requires you to appoint a registered agent with a physical address in that jurisdiction. Each state's Secretary of State enforces this requirement independently.

Can a registered agent resign, and what should I do if they do?

Yes, a registered agent can resign by providing written notice to the LLC and filing a resignation with the Secretary of State, typically with 30-60 days' notice depending on state statute. You must appoint a replacement and file the necessary amendment before the resignation becomes effective to avoid falling out of compliance.
