Can I be my own registered agent in Illinois?

Yes, if you are an individual who lives in Illinois and you are reliably available at an Illinois street address that serves as the registered office. A member, manager, officer or employee can serve. The LLC or corporation itself cannot act as its own agent, and a P.O. box alone is not an acceptable registered office.

How much does it cost to change a registered agent in Illinois?

The Secretary of State charges $25 to file a statement of change of registered agent and/or registered office, on Form LLC-1.36/1.37 for LLCs or BCA-5.10/5.20 for corporations. Expedited handling adds $50. LLCs in good standing can file the change online; card payments carry a processor fee.

How much is a registered agent in Illinois?

Serving as your own agent is free. Commercial registered agent services commonly charge roughly $50 to $300 a year, based on national providers' published prices; that is a market estimate, not a state fee. The only state charges are $25 when you change agents and the yearly annual report ($75 for an LLC).

What happens if my Illinois registered agent resigns?

The agent must mail you a copy of its resignation at least 10 days before filing it, and the resignation cannot take effect sooner than 30 days after filing. You then have 60 days after the notice to put a new agent on record. Missing that deadline makes the company delinquent and not in good standing.

Illinois Registered Agent Requirements in 2026: Who Can Serve, How to Change and What It Costs

Q: When is the Illinois LLC annual report due and what is the late fee?

The report is due before the first day of the LLC's anniversary month, the month it was formed, and costs $75. If it is still unfiled by the first day of the second month after the anniversary month, a $100 penalty applies, plus $100 for each further year of delinquency. Continued non-filing leads to administrative dissolution.

Every LLC and corporation on the Illinois Secretary of State's register must name a registered agent: a person or company in Illinois that accepts lawsuits and official notices for the business. It looks like a box to tick on the formation form, but the agent is a continuing legal duty, and Illinois attaches penalties, loss of good standing and eventually dissolution to getting it wrong. This guide explains the statute, who can serve, the choice between doing it yourself and paying a service, how to change agents, what happens when one resigns, and how the annual report ties in. Fees come from the Limited Liability Company Act's fee schedule and the Secretary of State's filing pages, checked in October 2026.

Quick answer

Under 805 ILCS 180/1-35, every Illinois LLC must continuously maintain a registered agent and registered office in Illinois. The agent can be an Illinois resident (including you) or a business entity authorized to do business in Illinois, but not the company itself. Changing agents costs $25 on Form LLC-1.36/1.37 (BCA-5.10/5.20 for corporations), and the LLC annual report costs $75 each year.

Being your own agent is free; commercial agents are a market cost of roughly $50–$300 a year
A resigning agent must give you notice 10 days before filing; replace it within 60 days
Late annual report: $100 penalty, then dissolution if still unfiled
No reachable agent? Plaintiffs can serve the Secretary of State instead
Reinstating a dissolved LLC costs $200 plus everything owed

What a registered agent does in Illinois

The registered agent is the company's official address for legal papers. When someone sues your LLC, the process server delivers the summons and complaint to the agent at the registered office. Subpoenas, garnishment notices and some state correspondence go there too. The agent's job is to be available at that address during normal business hours, accept what arrives, and pass it to the company quickly so that deadlines to respond are not missed. The time to respond to a lawsuit is short, so a few days' delay in forwarding can matter.

The agent does not run the business, does not act as your lawyer and has no authority to sign for the company beyond accepting service. The registered office is also not necessarily where you work. For corporations, the Business Corporation Act says expressly that the registered office need not be the same as the place of business; what matters is that the agent's own business office is the registered office.

Illinois records the agent's name and the registered office address in its public business database. Anyone can look up your company and see both, which is why privacy is one of the main reasons owners hire a service rather than listing their home.

Who can be a registered agent: the statutory rules

For LLCs (805 ILCS 180/1-35). Each LLC, and each foreign LLC authorized in Illinois, must continuously maintain in the state a registered agent and a registered office. The agent must be either an individual resident of Illinois or another person, meaning a business entity, authorized to transact business in Illinois. The Secretary of State's guide for organizing LLCs adds that the agent may be, but does not have to be, an organizer, manager, member or employee, and that the LLC may not act as its own agent.

For corporations (805 ILCS 5/5.05). An individual agent must be an Illinois resident whose business office is identical with the registered office. An entity agent can be a domestic or foreign corporation, LLC, limited partnership or limited liability partnership that is authorized to do business in Illinois, is authorized by its stated purpose to act as an agent, and has a business office identical with the registered office. A corporation cannot be its own agent.

The registered office. The office must be an Illinois street or road address, or a rural route and box number. The Secretary of State's forms say plainly that a P.O. box alone is not acceptable, and the address must match the agent's business office. A virtual mailbox or mail-forwarding address does not meet the requirement, because nobody is there to accept service in person.

Being your own agent vs hiring a service

Serving yourself. It costs nothing, and for an owner with a shop or office in Illinois that is staffed every weekday, it is often the sensible choice. The trade-offs are privacy and availability. Your address is public on the Secretary of State's records, and if a process server arrives while you are on a job site or on holiday, the risk of a missed lawsuit falls on you. If you run the business from home, your home address becomes the company's public legal address.

Hiring a commercial agent. You pay a yearly fee and the provider's Illinois office becomes your registered office. Most services scan and email documents on the day they arrive, and many send reminders for the annual report. For owners who live outside Illinois, a service is the practical answer, since a non-resident individual cannot serve. Illinois does not run a separate licensing scheme for commercial agents, so check a provider's track record and exactly how it notifies you before you sign up. Prices commonly fall somewhere between $50 and $300 a year based on national providers' published prices; treat that range as a market estimate rather than an official figure.

A trusted third party. Some owners name their accountant or lawyer, who already works from an Illinois office and handles legal papers routinely. Get their written agreement and agree how they will forward documents.

Naming the agent when you form the company

When you file articles of organization for an Illinois LLC ($150, or $250 in total for 24-hour service), you enter the registered agent's name and the registered office address. A series LLC costs $400. Corporations name the initial agent and office in their articles of incorporation, and foreign companies do the same when they apply for authority to do business in Illinois.

Line up the agent before you file. If you use a service, sign up first and copy its exact name and Illinois street address into your filing. A mismatch between the name and address on file makes service harder and can trigger a rejection. Keep the agent's contact details with your company records and give them a current email for forwarding.

Changing your registered agent or registered office

An LLC changes its agent, its registered office, or both, by filing a statement of change on Form LLC-1.36/1.37. Corporations use Form BCA-5.10/5.20, and the change of agent must be authorised by a resolution of the board of directors. The fee for either is $25, with an optional $50 for expedited handling.

Changing your Illinois registered agent

1
Line up the new agent
Confirm the person or company agrees to serve, and get their exact name and Illinois street address.
2
Check your company is in good standing
Only LLCs in good standing can file the change online. If an annual report is overdue, file it first.
Tip: Overdue reports and penalties block other filings until they are cleared.
3
File the statement of change
Online through the Secretary of State's agent-change service, or on Form LLC-1.36/1.37 (BCA-5.10/5.20 for corporations) by mail or in person.

4
Pay $25
Card payments online carry a payment processor fee. Expedited handling costs $50 more.
5
Tell the old agent and keep the record
Cancel the old service so it stops billing you, and save the filed statement with your company records.

Annual report timing. Unlike some states, Illinois does not let you change the agent inside the online annual report. The Secretary of State's instructions tell filers to submit the annual report showing no changes and then file the agent change separately. So budget $25 for any switch, whenever you make it.

When your agent moves. The statute lets the agent itself change the registered office address for the companies it represents under section 1-37. If a commercial agent relocates within Illinois, it should handle that filing, but look up your company afterwards to confirm the new address shows.

When an agent resigns

An agent may resign at any time, but section 1-35 sets a process. The agent must send you a copy of the resignation notice by registered or certified mail to your principal office at least 10 days before filing it with the Secretary of State. The notice must name the company and the agent, give the current registered office, state the effective date and the principal office address the agent used. The effective date cannot be sooner than 30 days after the notice is filed.

You then have 60 days after the agent's notice to place a new agent on record. If you miss that deadline, section 50-15 declares the company delinquent and not in good standing, and the Secretary of State's form warns of a $100 penalty for failing to appoint and maintain an agent within the 60 days. Failing to maintain an agent is also one of the statutory grounds for administrative dissolution in section 35-25.

The notice goes to the principal office address on file. If that address is out of date, you may never see it. Commercial agents most often resign because an invoice went unpaid, so keep billing contact details current too.

What happens if you have no agent

Service on the Secretary of State. Section 1-50 makes the Secretary of State your agent for service when the company fails to appoint or maintain an agent, or when the agent cannot be found with reasonable diligence at the registered office. It also applies to a dissolved LLC for five years after dissolution, and to foreign LLCs whose authority has been revoked or withdrawn. The plaintiff serves the Secretary of State with the papers and the statutory fee, mails notice by registered or certified mail to your last registered office and to any other address likely to reach you, and files an affidavit of compliance. The case then proceeds. If the mail goes to an address nobody checks, the first you hear of the lawsuit may be a default judgment.

Loss of good standing and dissolution. While delinquent, the Secretary of State will not file other documents for the company, such as amendments, and will report it as not in good standing to anyone who asks, which can derail a bank loan, a licence renewal or a sale. Persisting in the default can end in administrative dissolution.

The annual report, penalties and reinstatement

Every Illinois LLC and foreign LLC files an annual report, which confirms the registered agent and office along with the company's managers or members. It is due before the first day of the company's anniversary month, the month in which it was formed or admitted, and costs $75. Series LLCs pay an extra $50 for each series with a certificate of designation. The duty to file is yours whether or not you receive a reminder.

If the report is still not filed by the first day of the second month after the anniversary month, the Secretary of State can impose a $100 penalty, plus another $100 for each year or part of a year from the second year of delinquency. The Secretary of State's instructions describe the sequence: the company is first delinquent, moves to penalty status if unfiled 60 days after the due date, and is administratively dissolved if still unfiled 120 days after it became delinquent. When you file online, every penalty accrued to date must be paid with the report.

Reinstatement for $200 plus all reports, fees and penalties

Corporations pay a $75 annual report fee plus franchise tax, due before the first day of the anniversary month. A late report adds a penalty of 10% of the franchise tax due, and late franchise tax adds 2% a month or part of a month.

Reinstatement. A dissolved LLC can apply for reinstatement on Form LLC-35.40/45.65 for $200, filing with it every delinquent annual report and paying all fees and penalties. If the agent or office changed while the company was dissolved, a statement of change goes in with the application. The Secretary of State's form notes that a dissolved LLC's name is not available to another LLC until three years after the notice of dissolution, so reinstating within that time keeps your name safe.

Illinois registered agent costs: worked examples

A Chicago contractor as his own agent. Tomás forms an LLC in March for $150, naming himself as agent at his office on the Northwest Side, where his office manager is present every weekday. His agent cost is $0. His first annual report, due before March 1 of next year, costs $75. When he moves offices two years later, he files a statement of change for $25.

A remote founder in Wisconsin. Priya forms an Illinois LLC for a Chicago warehouse lease but lives in Milwaukee, so she cannot serve herself. She hires a commercial agent for about $125 a year (market estimate) and names it in her articles. Her first-year cost is $150 plus about $125, roughly $275, and from then on about $200 a year including the $75 report.

A home business owner who wants privacy. Jordan listed his Oak Park home as the registered office. He switches to a commercial agent mid-year: about $125 a year for the service plus $25 for the statement of change, roughly $150 for the first year.

A company whose agent resigned. A Peoria LLC's commercial agent resigns over an unpaid invoice and mails notice to a principal office the owners left last year. Nobody responds within 60 days, the company becomes delinquent, and its next annual report also goes unfiled. To recover, the owners file the overdue report with the $100 penalty and a $25 statement of change naming a new agent: $75 + $100 + $25 = $200, before any penalty for the missed agent deadline. Had they waited until dissolution, reinstatement alone would add $200.

Common mistakes

Using a P.O. box or virtual mailbox. The registered office must be a street address where the agent is actually present. Mail-drop addresses are rejected or, worse, accepted and then fail when a process server visits.

Naming someone who moves out of Illinois. An individual agent must be an Illinois resident. If your agent moves away, they stop qualifying; file a change.

Leaving the principal office address stale. Resignation notices and Secretary of State mail go to the address on file. Update it whenever you move.

Waiting for the annual report to change agents. Illinois handles the agent change as a separate $25 filing, so there is no saving in waiting, and a resignation starts a 60-day clock.

Assuming the agent files your annual report. Some services do it as an add-on; many only send a reminder. The filing and the $75 fee stay with you.

What to do next

Look up your company on the Secretary of State's business entity search and confirm the agent and registered office shown are right. If you are forming a new LLC, decide whether you will serve yourself or hire a service, check your name with our LLC name checker, and then work through local licensing in our Illinois business license guide. If a lender or buyer asks for proof that your company is current, see our guide to the certificate of good standing. For how agents work elsewhere, compare our Georgia, Texas and Delaware guides.
