Operating in Illinois With a Business Formed Elsewhere
A clean Illinois registered agent setup for $99 per year. You get the office address on file, scanned legal mail, and compliance reminders ahead of state deadlines.
Your company was organized under another state's law, and now part of its work happens in Illinois: people on payroll here, a local office, or a regular flow of Illinois jobs. Illinois calls that company "foreign," and a foreign LLC has to be admitted by the Secretary of State before it transacts business in the state.
The admission filing names an Illinois registered agent, so you need one in place first.
Triggers for Illinois Foreign Qualification
The Illinois Limited Liability Company Act requires admission "before transacting business in this State" but never says what that phrase covers. Section 45-47 of the Act takes the opposite approach and lists nine activities that, on their own, are not transacting business:
- Bringing, defending, or settling any court case or other proceeding
- Holding member or manager meetings and handling other internal affairs
- Maintaining bank accounts
- Keeping an office or agent solely to transfer and register the company's own securities
- Making sales through independent contractors
- Soliciting orders, by mail or through employees or agents, when each order needs acceptance outside Illinois to become a contract
- Owning real or personal property here, with nothing more
- One isolated deal completed within 120 days, as long as it is not part of repeated deals of a like nature
- Having a member or manager who lives in Illinois
That list is not exhaustive. A local office, employees based here, or repeated Illinois deals of the same kind are not on it, and those are the situations where the question usually comes up. For a close call, ask an Illinois business attorney.
Your Illinois Registered Agent's Role
Under Section 1-35 of the Act, every LLC admitted to do business here must continuously maintain both an Illinois registered agent and an Illinois registered office. Your agent:
- Is the person or company on whom lawsuits and other legal process can be served
- Receives mail the Secretary of State sends, which goes to the registered office address
- Must be an Illinois resident, or a business entity authorized to act as an agent in Illinois; the LLC cannot be its own agent
The Secretary of State asks for a registered office at an Illinois street address that is identical to the agent's business office. A P.O. box alone, or a "c/o" address, is not acceptable. When an agent resigns, a new one has to be on record within 60 days.
How to Foreign-Qualify
Ready when you are. Ordering takes about five minutes.
Order HereStep 1: Certificate of Good Standing. Order a certificate of good standing or existence from the official who keeps LLC records in your home state. Form LLC-45.5 says the certificate must be authenticated within the last 60 days, so request it close to the date you plan to file.
Step 2: Appoint an Illinois registered agent. Pick an Illinois resident or a business entity authorized to serve as an agent here, with an Illinois street address for the registered office.
Step 3: File with the Illinois Secretary of State. An LLC files Form LLC-45.5, the Application for Admission to Transact Business, in duplicate with the Department of Business Services in Springfield. Include the certificate and the $150 filing fee, paid by certified check, cashier's check, Illinois attorney's check, C.P.A.'s check or money order. Form LLC-45.5 is not among the Secretary of State's online services, so it goes on paper. The form also asks when the company first conducted business in Illinois, if it already has. If your name is not available here, submit Form LLC-1.20 with the application to adopt an assumed name, and use that name for Illinois business. A foreign corporation uses Form BCA 13.15, the Application for Authority to Transact Business in Illinois, instead.
Step 4: Wait for approval. No standard processing time is published for Form LLC-45.5. Expedited handling costs $100 more and has to be requested in person at the Springfield or Chicago office.
Step 5: Meet ongoing obligations. Every year, the $75 annual report is due ahead of the first day of the anniversary month, meaning the month in which your admission was filed. A late report leaves the company not in good standing; if it is still missing when the second month after the anniversary month begins, the Secretary of State can add a $100 penalty, plus $100 for each year from the second year on, and an unfiled report is grounds for revoking your admission. Keep your registered agent current, and handle any Illinois Department of Revenue filings that apply to you, such as Form IL-1065, the Partnership Replacement Tax Return, for an LLC taxed as a partnership with income allocable to Illinois. When you leave, file Form LLC-45.40, the Application for Withdrawal, for $5.
Risks of Operating Without Registration
A foreign LLC that does business in Illinois without being admitted:
- Cannot maintain a civil action in any Illinois court until it is admitted, though it can still defend one
- Owes the state every fee it would have paid had it been admitted on time and filed its reports, along with the penalties those carry
- Is liable for a penalty of $2,000, plus $100 per month or fraction of a month it keeps operating unadmitted, if it is not admitted within 60 days of starting business here
- Can be sued by the Attorney General to restrain it from transacting business in Illinois
- Has made the Secretary of State its appointed agent to receive any notice, process, or demand
Its contracts stay valid, and members are not personally liable for company debts simply because the LLC was never admitted.
