Yes. Every LLC, in every state, must continuously maintain a registered agent — it's a condition of existing, not an optional extra. The agent is your LLC's official point of contact: a person or company with a physical street address in the state where you formed, available during normal business hours to receive lawsuits (called "service of process"), tax notices and state correspondence, and forward them to you. What's genuinely optional is who fills the role and what you pay for it — from $0 doing it yourself to $249/yr for a premium service. This guide covers the rules, your options with real prices, and how to decide.

What does a registered agent actually do?

Three jobs. Receive legal papers: if your LLC is sued, the court papers are served on your agent — miss them and you can lose a lawsuit by default without ever knowing it existed. Receive official mail: annual report reminders, tax notices and state correspondence go to the agent's address. Be findable: the agent's name and address sit in the public record so anyone — courts, the state, the public — can reach your business formally. A good commercial agent also scans and uploads documents the day they arrive and reminds you about filing deadlines; a DIY agent is you, remembering all of that yourself.

What are the rules for a registered agent?

  • Physical street address in the formation state. Not a PO Box, not a virtual mailbox in most cases — a real address where a person can be handed documents.
  • Available during normal business hours whenever process might be served.
  • An adult individual or an authorized company. In most states the LLC itself cannot serve as its own agent, but an owner, member or employee individually can.
  • One agent per state. Form in one state and register as a foreign LLC in another, and you need an agent with an address in each state.
  • Always current. If your agent moves or resigns and you don't update the state, your LLC can fall out of good standing — the state must always have a working address for you.

Registered agent address vs. business address: what's the difference?

Founders mix up three addresses, and they are not interchangeable. Your registered agent address is the in-state street address on file for legal service — it must be physical, staffed during business hours, and it appears in the public record. Your principal business address is where the company is headquartered for state records; it can be your office or home and is also typically public. Your mailing address is simply where ordinary correspondence goes and can safely be a PO Box. A commercial registered agent only replaces the first one — but because the agent address is the most exposed of the three, that single change is what keeps your home address out of the public listing for many home-based businesses.

What are your registered agent options, and what do they cost?

There are three routes, and the prices below are from our registered agent comparison (checked October 2026):

OptionCostBest for
Yourself (DIY)$0Founders with a stable in-state street address who are present during business hours
Northwest Registered Agent$125/yrPrivacy-focused founders; a well-known agent-only specialist
ZenBusiness$199/yrFounders already using its formation/compliance platform
LegalZoom$249/yrFounders who formed through LegalZoom and want everything in one account

A fourth route — naming a trusted adult friend, family member or your accountant/lawyer with an in-state address — costs $0 too, but make sure they understand the job and will be at that address for years. Note that "free first year" agent offers bundled with formation services renew at the full rate; compare the renewal price, not the teaser. And whatever you choose, the agent fee is on top of your state fees — see both together in the LLC cost calculator.

Should you be your own registered agent, or hire a service?

DIY makes sense if you have a commercial address or don't mind your home address being public, you (or someone reliable) are physically there during business hours, and your LLC is in your home state. It saves $125–$249 every year, forever.

A service earns its fee if any of these sound like you:

  • You work from home. Your agent address is public record — a service keeps your home address off it.
  • You travel, work irregular hours, or might move. Missed service of process can mean a default judgment; a service's whole job is never missing it, and you don't have to update the state every time you relocate.
  • You're registered in multiple states — one provider covers all of them with one dashboard, instead of a different arrangement per state.
  • You'd like deadline insurance. Most services remind you about annual reports and compliance dates, the filings whose late fees quietly eat new businesses.

How do you change your registered agent later?

You're never locked in. Changing agents is a routine state filing — typically a short form (often called a Statement of Change) filed with the same agency that holds your Articles, and many states charge little or nothing for it, though fees and forms vary by state. Your state's cost page links the official site with the current form. Two timing tips: appoint the new agent before removing the old one so there's no gap in coverage, and if you're switching to DIY, use an address you expect to keep — every move means another update filing.

Frequently asked questions

Can I be my own registered agent?

Yes, in every state — as long as you're an adult with a physical street address in the state where the LLC is formed and you're available at that address during normal business hours. It costs $0. The trade-offs are privacy (your address becomes public record) and reliability (you must never miss legal papers). Full decision framework in the section above.

Can I use a PO Box as my registered agent address?

No. States require a physical street address where documents can be hand-delivered during business hours, and a PO Box doesn't qualify. A commercial agent service solves this by lending you their real address — one of the main reasons founders pay for one.

What happens if my LLC doesn't have a registered agent?

You can't complete formation without naming one, and letting the appointment lapse afterward can push your LLC out of good standing and toward administrative dissolution. Worse, lawsuits don't wait: if there's no working agent to serve, you may learn about a case only after a default judgment. Keep the appointment current — it's the cheapest compliance there is.

Do I need a different registered agent for each state?

Yes — an agent must have a physical address in each state where your LLC is formed or foreign-registered. That's one reason multi-state businesses use a national service: one provider, one bill, coverage in every state. See how foreign registration works in our foreign LLC guide, and compare providers in the registered agent comparison.
