What Is an Illinois Registered Agent?
A registered agent is a person or business that is designated to accept service of process (legal mail) on behalf of your Illinois business. Illinois law requires registered businesses to have a registered agent. You’ll also need to include your registered agent’s name and address on state formation documents you file with the Illinois Secretary of State.
Registered agents in Illinois must:
- Accept legal documents and official mail on behalf of your Illinois business and deliver them to you as fast as possible.
- Have a physical address (no P.O. Boxes) in the state of Illinois where they can accept legal documents (service of process) and official mail like tax notices. This location is called a registered office.
- Maintain normal business hours (9 AM to 5 PM).
These are just the minimum legal requirements for registered agents in Illinois. At Northwest, we believe in going above and beyond expectations to ensure top speed, security, privacy, and support for all of our clients.
Yes. Choose or hire an agent first, then form your LLC or corporation. The Secretary of State’s Corporations Division will reject your business registration filing if you don’t include your registered agent’s contact information when you submit your documents.
When you hire Northwest as your registered agent in Illinois, you’ll find all the forms and instructions you need to complete your filing instantly after you place an order.
There are a few reasons a registered agent is needed for your Illinois business:
- State law (Illinois Compiled Statutes 805 ILCS 180/1-35) requires all legitimate, registered businesses to appoint one.
- The Secretary of State will reject your business filing if you don’t appoint a registered agent.
- A registered agent requirement gives the public and the state a reliable way to contact your business.
You can be your own business’s registered agent in Illinois. However, the role’s requirements mean most business owners hire a registered agent service instead. Why? Because even though being your own registered agent is free, an Illinois registered agent’s name and address becomes part of the public record. Additionally, a registered agent is required to be available to accept service of process during normal business hours.
Serving a registered agent is legal proof of notification. Whether you receive the documents your Illinois registered agent signs for or not, once they accept the documents, you’ve legally been notified. This is a serious responsibility and we don’t take it lightly. Here’s how it works:
- A process server, the county sheriff, or any third party will walk into our Springfield office and hands us the documents (service of process), then we sign for them.
- The process server then gives an affidavit (a receipt of service) to the court which states that they served us.
- If you’ve hired us, long before the server hands in their affidavit to the court, you’ve received your documents because we scanned them to your online account within minute of having been served.
- Perform an Illinois business name search.
- Type in the name of the company you’re searching for.
- Find the registered agent’s name and registered office street address in the search results.
If you want to legally notify a business through their Illinois registered agent service, just send a certified letter directly to the registered agent at their registered office address.
How Do I Change My Illinois Registered Agent?
Changing your registered agent in Illinois is pretty straightforward. Here’s how it works:
- File a Statement of Change of Registered Agent form with the Illinois Secretary of State.
- If you have a corporation, you file Form BCA 5.10/5.20, Statement of Change of Registered Agent and/or Registered Office.
- If you have an LLC, you file Form LLC-1.36/1.37, Statement of Change of Registered Agent and/or Office.
- If you place an order with us, the form will be available instantly.
- It’s a simple process, but for more info, see our change your Illinois registered agent page.
