Who Can Serve as Your Illinois Registered Agent?
Option 1: Yourself (LLC Owner/Manager)
You can serve as your own registered agent if you are an Illinois resident with a physical Illinois address. This is free but means your address will be public record, and you must be at that address during business hours.
Option 2: Another Individual
A trusted friend, family member, or employee who is an Illinois resident with a physical address can serve as your registered agent.
Option 3: Commercial Registered Agent Service
Professional registered agent services ($50–$300/year) provide a reliable registered address, forward documents promptly, and maintain your privacy. This is the most popular option for business owners who work remotely or travel frequently.

- Be physically present (or have someone present) at the registered address during business hours
- Accept service of process and forward documents to the LLC promptly
- Maintain a current Illinois street address on file with the Secretary of State
