A DBA name is commonly referred to as an “assumed name” in this state.
In Illinois you can file your DBA (aka trade name, assumed name or fictitious business name) yourself with your local County Clerk’s office. Or, use a legal document service such as LegalZoom to handle the entire process for you.
LegalZoom charges $99.00 (plus state filing fees) for Illinois DBA’s. Click here to learn more about pricing.
