Registered Agent: What It Is, What They Do, and How to Choose One (2026)

What a Registered Agent Is and What They Actually Do

A registered agent (also called a statutory agent, resident agent, or agent for service of process, depending on the state) is the officially designated recipient of legal and government documents for your LLC. The registered agent is your business's permanent, reliable mailbox for anything official.

What a registered agent receives on your behalf:

• Service of process: When someone sues your LLC, a process server physically delivers the lawsuit papers (the summons and complaint) to your registered agent. This is the most critical function: if the registered agent misses this delivery, you may not know you have been sued, and the court can issue a default judgment against your LLC without your participation.
• State government correspondence: Annual report reminders, notices from the Secretary of State, tax correspondence, and notices about your LLC's good standing status.
• Compliance notices: Warnings if your LLC is at risk of administrative dissolution for missing annual report filings or fee payments.
• Official filings from the state: Copies of your LLC formation documents and any state-initiated changes.

The registered agent does not manage your business, make decisions, or have any ownership interest. They are purely a legal mailbox with a physical address who accepts documents and forwards them to you.

Legal Requirements in Every State

Every US state requires every LLC to maintain a registered agent at all times. The requirements are consistent across all 50 states, with minor state-specific variations:

• Physical street address required. The registered agent must have a physical street address in the state where the LLC is registered. PO boxes, mailbox store addresses (like UPS Store boxes), and virtual mail services are not acceptable in any state. A process server must be able to physically deliver documents.
• Must be available during normal business hours. The registered agent must be physically present at the registered address during standard business hours (typically 9 AM to 5 PM, Monday through Friday) to accept documents.
• Must be an eligible person or entity. The registered agent must be either: an individual adult (18 or older) who is a resident of the state, or a business entity (corporation, LLC) that is authorized to do business in that state.
• Must consent to the appointment. In most states, the registered agent must consent to serving in that role. Some states (Florida, for example) require the registered agent to sign the Articles of Organization as formal confirmation.
• Must be continuously maintained. You cannot let the registered agent role lapse. If your registered agent withdraws, moves, or becomes unavailable, you must file a Statement of Change of Registered Agent with the state immediately. An LLC without an active registered agent faces delinquency and potential administrative dissolution.

The registered agent's name and address appear in your Articles of Organization: a public record searchable by anyone, including data brokers, marketers, and anyone who searches your business name.

Why Missing a Document Is Catastrophic

The stakes for missing service of process are not theoretical. Here is exactly what happens:

1. A plaintiff files a lawsuit against your LLC.
2. The court issues a summons directing the defendant (your LLC) to respond by a specific date.
3. A process server attempts to deliver the summons to your registered agent's address.
4. If the registered agent is unavailable, has moved, or does not forward the document promptly: you do not know about the lawsuit.
5. The response deadline passes with no response from your LLC.
6. The plaintiff moves for a default judgment: the court rules in their favor automatically, without hearing your side.
7. The plaintiff now has a legal judgment and can pursue collection, including bank account levies and liens.

Default judgments happen. They are not rare. And they are extraordinarily difficult to overturn. The registered agent is the one mechanism preventing this scenario, which is why reliability is the most important factor when choosing one.

DIY Registered Agent vs. Professional Service

For home-based business owners, being your own registered agent means your home address is permanently tied to your business in a searchable public database. Data brokers harvest these records. This leads to unsolicited sales calls, physical junk mail to your home, and in some cases unwanted attention that raises safety concerns. For $125/year, most home-based business owners find this a worthwhile trade.

Cost Comparison: Major Registered Agent Services (2026)

Prices as of May 2026. CT Corporation is primarily for mid-market and enterprise businesses. Bizee and ZenBusiness privacy policies reviewed May 2026. "Data selling" means sharing customer contact information with marketing partners.

Northwest stands out for combining the second-lowest price ($125/year) with the strongest privacy policy (no data selling) and what most reviewers rate as the best customer support. Bizee is $6/year cheaper but permits sharing data with marketing partners.

How to Choose a Registered Agent Service

The five factors that actually matter:

1. Reliability and physical presence. The service must have actual offices in all states where you need coverage, not just a mailing address. Northwest maintains physical offices in all 50 states. This is the core requirement: the agent must be physically present to accept service of process.
2. Document handling speed. When a document arrives, how quickly does the service scan and notify you? Some services only notify you by mail; others upload a digital scan the same day. Same-day electronic notification is the standard to look for. Northwest scans every document locally, unlike many services that only scan certain documents.
3. Privacy policy. Read whether the service sells your contact information to third-party marketers. This determines whether using the service results in increased spam calls and emails. Northwest does not sell data. Bizee's privacy policy permits it.
4. Total multi-year cost. Compare true 3-year costs including formation fees, not just annual RA fees in isolation. A service advertising "$0 formation" with $199/year RA costs more over 3 years than Northwest's $39 formation with $125/year RA.
5. State coverage for foreign qualifications. If you expect to expand your LLC to other states, you need a registered agent in each state. Services that offer multi-state discounts (Northwest discounts for 10+ states) reduce the cost of expansion.

How to Change Your Registered Agent

You can change your registered agent at any time. The process:

1. Choose a new registered agent and get their consent to serve (most professional services handle this automatically when you sign up).
2. File a Statement of Change of Registered Agent (or equivalent form) with your state's Secretary of State. This is typically a simple 1-page form.
3. Pay the state filing fee, typically $20 to $50.
4. The change takes effect when the state processes the filing, usually within a few business days.

You should change your registered agent immediately if: your current agent resigns or goes out of business, you move to a new state and need a local agent, or you are dissatisfied with your current service's reliability or pricing.

Registered Agent Requirements for Foreign LLCs

When your LLC expands into additional states (called "foreign qualification"), you need a separate registered agent in each additional state. This is the same requirement as your home state: a physical address in that state, available during business hours.

If you form a Wyoming LLC and foreign qualify in Texas, you need a Wyoming registered agent and a Texas registered agent. If you then expand to Florida, you need a Florida registered agent as well. Each state must always have a designated agent.

Professional registered agent services that operate nationally can cover all your states through a single account, often with multi-state discounts. Northwest charges $125/year per state for 1 to 9 states and discounts to $100/state for 10 to 50 states, making national coverage manageable for businesses with multi-state operations.

Our Analysis: 3-Year Cost of DIY vs. Professional Service

We modeled the true 3-year cost of DIY registered agent (yourself) versus Northwest, accounting for the privacy benefit and the realistic risk cost of the DIY approach.

The real question is whether $375 over 3 years (or $250 if using Northwest for formation) is worth keeping your home address off public databases, having a professional handle document receipt so you can travel freely, and getting compliance reminders to prevent missing annual report deadlines.

For most home-based business owners, the answer is yes. The $125/year cost is less than $11/month. The alternative: your home address is permanently associated with your business in state databases that data brokers actively harvest, and you must be available at home during all business hours or risk missing a lawsuit notification.

FAQ

What is a registered agent for an LLC?

A registered agent is a person or company with a physical street address in your LLC's formation state who receives official legal documents (lawsuits, government notices) on your LLC's behalf. Required in every state for every LLC at all times. Their address is public record.

Can I be my own registered agent?

Yes, in most states, if you have a physical street address (not a PO box) in the state and are available there during normal business hours. Downsides: your home address becomes public record and you must always be physically available at that address during business hours, every business day.

How much does a registered agent cost?

Professional registered agent services cost $99 to $299/year. Northwest Registered Agent: $125/year. Bizee: $119/year. ZenBusiness: $199/year. LegalZoom: $249/year. DIY (yourself): $0 but your home address becomes public.

What happens if my LLC has no registered agent?

An LLC without an active registered agent faces delinquency status with the state and risks administrative dissolution, which voids your liability protection. If a lawsuit is filed during this time, you may not receive notice and face a default judgment. Always maintain a registered agent at all times.

Can I change my registered agent?

Yes, at any time. File a Statement of Change of Registered Agent with your state's Secretary of State. The fee is typically $20 to $50. The change takes effect when the state processes the filing, usually within a few business days.

What is service of process?

Service of process is the official legal procedure for delivering a lawsuit to the defendant. A process server physically delivers the summons and complaint to the registered agent's address. The registered agent then forwards it to you. Missing service of process can result in a default judgment against your LLC, because courts proceed without you if you do not respond by the deadline.
