Illinois Registered Agent

All limited liability companies (LLCs) and corporations in Illinois are required to appoint a registered agent.

Your Illinois registered agent can be yourself, a partner, or a registered agent service. Many small business owners use a service because they:

  • Offer a higher degree of privacy 
  • Reduce risk
  • Give owners the freedom to be absent from their registered office address during regular business hours

We’ll help you make the right choice for your business.

Recommended: Northwest Registered Agent offers free registered agent services with LLC or corporation formation ($29 plus state fees).

An Illinois registered agent serves as your business’s point of contact with the state and will also receive service of process in the event that a lawsuit is filed against you. 

Appointing a registered agent in Illinois is a legal requirement for both LLCs and corporations. This can be a registered agent service or an individual, so long as they:

  • Are at least 18 years old.
  • Have a physical address in Illinois.
  • Are always available during regular business hours at their registered office address.

  • Flexibility: Working with a third-party service — instead of acting as your own agent — will allow you to operate with more flexibility on a day-to-day basis. This is because you will not need to be present at your business’s address during normal business hours. 
  • Privacy: Since your registered agent’s name will become publicly searchable as soon as your LLC or corporation is registered, you can choose to hire a third-party service in order to protect your private information. 
  • Legal compliance: Several service providers offer additional compliance-related features, such as annual report reminders.

Can You Be Your Own Registered Agent?

Yes you can.

Being your own agent can be a good idea if you are operating with a relatively small budget. This is because it can be done free of charge, and so you will not need to pay for a third-party service (i.e., around $90 per year.). 

Having said that, it is important to consider the drawbacks of acting as your own agent before making a final decision. 

For example, acting as your agent will mean that you will need to always be physically present in your business’s address during regular business hours; you will also be solely responsible for going through all paperwork sent to you via the SOS. 

If you are forming a new LLC, it will make sense to hire a formation service that includes a free year of registered agent services. These can charge as little as $29 per formation (excluding state fees). 

If you are forming an LLC but prefer to file the paperwork yourself and act as your own registered agent, take a look at our How to Start an LLC in Illinois guide.

Benefits of Using a Registered Agent Service

Many businesses choose to use a registered agent service when they form an LLC. This is because it can offer a number of benefits, including:

  • Legal compliance: A registered agent service will ensure that you don’t miss an important legal document or notification (e.g., service of process, etc.) as a result of not being in your office (or as a result of a human error). 
  • Improved privacy: If you act as your own agent, your name and address will become public record on the Illinois Business Search. Using a registered agent service will help keep your information private.
  • Discretion: When it comes to legal disputes, you will want to avoid receiving lawsuit-related documents in front of your clients and/or some employees. 
  • Better storage: Your service will generally scan all documents received and upload them online in PDF form. This means that you will always be able to access them online, and won’t have to worry about losing an important document. 

A registered agent service can also be beneficial if you plan to expand into other states as a foreign LLC. This is because, otherwise, you would need to find an individual or business entity that is a resident — or is allowed to transact business — in each state that you want to register in.
