In this guide, we unpack who can be a registered agent for Illinois LLCs and provide a list of well-rated commercial registered agent providers in the Land of Lincoln.

Who can be a registered agent for an LLC in Illinois?
A registered agent is a person or business entity you appoint to receive official correspondence and legal documents on behalf of your LLC.
The incoming correspondence can include tax notices, compliance reminders from the Illinois Secretary of State, and legal notices (including service of process).
Any private person can be a registered agent for an Illinois LLC provided that they are:
- Above legal age (over 18).
- A resident of Illinois and has a street address in the state (it needs to be a physical address, not a P.O. box).
- Committed to being available at the registered office during normal business hours year-round in case service of process arrives.
If you don’t fit the above criteria (or prefer not to take this obligation), you can appoint a commercial registered agent service provider instead.
Your LLC is required by law to maintain a registered agent — failure to do so may result in losing good standing with the state. You will also need to update your registered agent information every year when you file an annual report for your LLC.
