Certificate of Authority in Illinois – Filing Service

Foreign Corporation in Illinois

If you are a corporation headquartered in another state and want to do business in Illinois, you will need a Certificate of Authority to operate in Illinois. You can get one by submitting paperwork as a foreign corporation with the Illinois Secretary of State, Corporations Division. After you submit your forms, the State of Illinois will return a filed certificate of authority to you. An Illinois foreign corporation is not to be confused with an out-of-country corporation. Any corporation not actually formed (created) in the State of Illinois is considered to be a foreign corporation.

We only charge for the state filing fees plus $100 to prepare and file the Foreign Illinois corporation Certificate of Authority form with the Illinois Secretary of State, Corporations Division. We also will obtain the documentation needed from your home state of incorporation to file your documents.

If you want to do the filing yourself: you just need to sign up for our Illinois registered agent service and the Illinois foreign corporation form is in your client account immediately. As an added bonus, we’ve included some filing tips on how to make the filing with the state. You are required to have a registered agent in Illinois anyway, so we try to make the process simple and easy for you, whether you want us to submit your papers or you want to do the filing yourself.

What Are My Next Steps?

Simply sign up for registered agent service first. You then can look at the foreign corporation form in your account online and also at our filing tips. If you decide not to do the filing yourself, you just click the “Add services” tab from your account, and add our filing services for $100 plus the state filing fees. Your account shows real time status of our work in progress. Once we are done with your Illinois foreign corporation registration, we always upload the filing in your online account, email it to you, and send you the original filed documents by mail.
