Home / Articles / Every LLC needs a registered agent. Here is what they do, whether you can be your own, and when a professional service is worth the cost.

What Is a Registered Agent and Do You Need One?

Every LLC in the United States must name a registered agent. The requirement is simple; the consequences of ignoring it are not. This covers what a registered agent actually does, what your options are, and how to decide which approach makes sense for your business.

The Short Answer

Every LLC needs a registered agent, no exceptions there. Whether you need to pay for one is a separate question: you can serve as your own for free if you have a reliable in-state address and can be present during business hours. A paid service earns its cost mainly for privacy, a travel-heavy schedule, or an LLC registered in more than one state.

A registered agent is a person or business designated to receive legal documents and official government mail on behalf of your LLC during normal business hours. Every state requires a physical street address in the state of formation, not a P.O. box. Failing to maintain one can cost your LLC its good standing, trigger administrative dissolution, or (the real risk) cause you to miss a lawsuit notice and lose by default without ever knowing you were sued.

What Does a Registered Agent Actually Do?

The registered agent has two core responsibilities:

  1. Receive service of process. This means accepting lawsuits, subpoenas, and other legal notices delivered by a process server or sheriff. These documents are time-sensitive. Missing them can result in a default judgment against your LLC without you ever knowing you were sued.
  2. Receive official state mail. Annual report reminders, tax notices, and correspondence from your Secretary of State are delivered to your registered agent's address.

The registered agent is not responsible for running your business or providing legal advice. The job is narrow: be present during business hours and forward what arrives. Requirements vary by state, so confirm specifics with your Secretary of State or a qualified attorney.

The SBA guide to choosing a business structure puts the registered agent requirement in context alongside other LLC compliance basics.

Do You Legally Need a Registered Agent?

Yes. Every state requires LLCs to keep a registered agent with a physical street address in that state. A P.O. box is not accepted anywhere. If you register your LLC in multiple states, each state needs its own registered agent.

Can You Be Your Own Registered Agent?

Yes, in most states. You need to be an adult individual (not just a business name), have a physical street address in the state of formation, and be present at that address during normal business hours, typically 9 a.m. to 5 p.m. Monday through Friday. If you cannot reliably check that box, the role is harder to hold than it sounds.

When to Use a Professional Registered Agent Service

A professional registered agent service is a company that holds the role for you, for an annual fee. It maintains a physical office in each covered state and accepts documents on your behalf during business hours.

Hiring a professional service makes sense in any of these situations:

The free LLC cost calculator includes registered agent fees in its first-year cost estimate alongside state filing fees and other startup costs.

How Much Does a Registered Agent Cost?

Serving as your own registered agent costs nothing beyond the usual formation fees. Hiring a professional service typically runs $100 to $300 per year per state. Many services discount for multi-year prepayments or for bundling multiple states, so multi-state accounts often cost less per state than paying one at a time.

How to Choose a Registered Agent Service

When shopping for a service, the features that matter most:

Before signing up, confirm the service is itself in good standing with the Secretary of State in each state it covers. A legitimate service is a registered business entity in those states. You can verify this on each state's Secretary of State website in a few minutes.

FAQs

Can I change my registered agent after forming my LLC?

Yes. File a change of registered agent form with your state, pay the small filing fee, and the change takes effect once the state processes it. Most states turn this around quickly, though exact timing varies.

What happens if my registered agent is not available when papers are served?

The process server may leave documents or attempt redelivery. Repeated failures to accept service can expose your LLC to serious legal complications, including a default judgment if a lawsuit notice is missed entirely. Consistent availability is the whole point of the requirement.

Does my registered agent have to be in the state where my LLC was formed?

Yes. Your registered agent must have a physical street address in the state where the LLC is registered. Registered in Delaware means you need a Delaware registered agent. Registered to do business in Texas means you need a separate Texas registered agent. Each state is independent.

Can an attorney or accountant serve as my registered agent?

Yes, in most states. Any adult individual with a physical street address in the state can serve, including an attorney or accountant who offers it as a service. Before agreeing, confirm they will be at that address during business hours and have a reliable process for forwarding documents the same day they are received.
