Registering a DBA in Illinois

Illinois has separate procedures for filing DBA (also called "Assumed Business Name"), depending on the type of company filing it:

1. DBA filed by an individual (sole proprietorship) or general partnership is called "assumed name", and it is registered by filing Assumed Name Certificate with the County Clerk in the county in which the business is located. (and not with Secretary of State's Office). The fee to file an assumed name certificate varies depending on the county. Application must be notarized prior to filing.

   KEEP IN MIND: Illinois requires to publish the Assumed Business Name Certificate of Registration Notice in a general circulation newspaper in the county of registration. Learn more about Illinois publication requirements here.
