Registering an Assumed Business Name

Businesses registering an assumed business name must:
  1. Complete an application
    Carefully read the instructions for submitting the Assumed Name Application.

  2. Submit legal notice
    Learn state requirements for completing a Copy of a Legal Notice to be Published.

  3. Publish the legal notice
    Specifications and deadlines for submitting the Legal Notice to local print media.

Fees

The filing fee for an initial application is $50. If the business is conducted at more than one location, an additional fee of $2 per additional location is charged.

Other requirements

If the original Assumed Name Certificate changes in any way (i.e. name or address changes, additions or deletions) the business must submit notification to the Cook County Clerk's office.

By state law, businesses are required to file an Assumed Business Name Certificate in each county in which the person(s) conducts, transacts or intends to transact business under the assumed name (i.e., any county in which a business maintains an address).

Contact the appropriate county office for information about registering business names in other nearby counties.
