Operating In Illinois as a Corporation from Another State

You can operate in Illinois if your corporation is located in another state. For example, my corporation was filed in Delaware. You should look into the pros and cons of the corporation laws in each state to decide what works best for you and your company.

In order to operate in Illinois you must file for permission to do business in Illinois. The IL Secretary of State will then assign you an Illinois File Number which you will need to complete the Reg-1 Form for your Resale ID.  When you complete the Reg-1 you will put the letter "F" before your file number, denoting foreign. If your corporation was located in Illinois you would put a "D" before your file number, denoting domestic. You will still file your sales tax in Illinois for sales made within the state, but you will renew your corporation annually in the state where it is filed. You can also obtain the Illinois DBA name for your corporation.
