What Is a Registered Agent and Do I Need One for My LLC?

By Bill Stilwell · Last reviewed October 17, 2026

The short answer

A registered agent is the person or company that receives lawsuits and official government papers for your business. The U.S. Small Business Administration (SBA) says limited liability companies (LLCs), corporations, partnerships, and nonprofit corporations need one before they file, and the agent must be located in the state where you register. You can often serve as your own agent or hire a service. Either way, keep a current record of the agent’s name, address, and acceptance, and update the state right away when anything changes.

What this means

Every state wants a reliable way to reach your business. The registered agent is that contact. When someone sues the business, or the state sends a notice about annual reports or taxes, the papers go to the agent at a physical address during business hours.

The agent can be:

You or another owner, if you have a physical address in the state and can be there during business hours
An employee or a trusted person who meets the state’s rules
A registered agent service, a company that does this for a yearly fee

The address must be a real street address in the state. Most states don’t allow a post office (P.O.) box for this.

The outline also asks you to keep the agent record (8.7.6). That means writing down the agent’s name, address, phone, email, the date they agreed to serve, and how they’ll forward papers to you.

Made-up example: Pine Hollow Pet Grooming LLC lists the owner as its agent at her home address. Two years later she moves. She updates her Google profile but forgets the state. A notice about her annual report goes to the old house. She finds out months later when the bank asks why the state shows her LLC as not in good standing.

Why it matters

Missed lawsuits. If papers go to an old address, a court can rule against the business before you even know about the case.
Missed state notices. Annual report reminders and penalty notices can go unanswered, and the business can fall out of good standing (see 9.1.5 State Good Standing).
Privacy. The agent’s address is part of the public state record. Data sites often copy it.
Filing gets blocked. The SBA says you need an agent before you file, so this can hold up formation.

Who this applies to

Every LLC, corporation, limited partnership, and nonprofit corporation needs a registered agent in its formation state. If you register as a foreign business in another state, you need an agent there too (see 9.1.6 Foreign Qualification).

Sole proprietors and general partnerships that never filed with the state usually don’t need one.

How to do it

Decide who will serve. Serving yourself saves the fee but puts your address in public records and requires someone to be there during business hours. A service costs money but keeps your address private and handles forwarding.
Confirm the person or company agrees. Some states ask the agent to sign or consent on the filing.
Check the address rules. It must be a physical address in the state. Read your Secretary of State’s instructions.
List the agent on your formation filing (see 9.1.1 Formation-State Registration).
Write the agent record. In your Master Business Record (see 5 Master Business Record), list the agent’s name, street address, phone, email, the date they accepted, the yearly fee and renewal date if it’s a service, and how papers get forwarded to you.
Test forwarding. If you use a service, log in to its portal and confirm alerts go to an inbox you check.
Update the state when anything changes. If you move or switch services, file the state’s change of agent form before the old agent stops serving.
Check the public record after any change to confirm the state shows the new agent.

What proof to keep

The formation filing showing the agent
The agent’s written consent, if your state uses one
The service agreement and renewal receipts, if you hire a service
Any change of agent filing and the state’s confirmation
A dated screenshot of the agent section of your state record

Keep these with your formation documents (see 8.7.1 Formation Documents).

Common mistakes

Letting a service lapse. If you stop paying, the service may resign as your agent. The state then has no one to send papers to.
Moving without updating the state. Updating Google, your bank, and your website but not the state record is very common.
Using an address you can’t staff. If no one is there during business hours, papers can’t be delivered.
Ignoring scam mail. Agents forward real notices, but owners also get official-looking offers. Check every notice against your Secretary of State’s site.
No backup. If you serve as your own agent and travel a lot, important papers may sit unopened.

When to get help from a pro

An attorney if you’ve been served with papers, if you’re unsure who can serve in your state, or if you’re registering in several states. Ask:

Can I serve as my own agent here, and what are the risks?
What happens if legal papers went to an old agent address?

Bill’s note

[Bill: add a short opinion. For example, whether you’d use a registered agent service to keep your home address off public records, and how that connects to keeping a home address off Google Maps.]

Questions people ask

Can I be my own registered agent? In many states, yes, if you have a physical address in the state and can be there during business hours. Check your state’s rules.

What does a registered agent do? Receives lawsuits and official state papers for your business and passes them to you.

Should I use a registered agent service? It can make sense if you want to keep your address out of public records, travel often, or work from home. It costs a yearly fee.

How do I change my registered agent? File your state’s change of agent form, usually with your Secretary of State, and confirm the public record updates.

Is the registered agent address public? Usually yes. It’s part of your state business record.

Audit check

Question: Does the state record show a current registered agent at a valid in-state street address, and does the business keep a written agent record?
Pass looks like: State record matches the agent record. Agent consent or service agreement on file. Forwarding tested. Renewal date tracked.
Fail looks like: Old address. Lapsed service. No one available during business hours. No internal record.
Evidence to collect: Dated screenshot of the state record, agent agreement or consent, and the Master Business Record entry.
