Do I Have to Register My DBA in Illinois?

Illinois DBA Registration

Under Illinois law, businesses must register alternative names by filing for a DBA if they operate under a name different than their legal name. Sole proprietorships must register any name besides the owner’s. Corporations and LLCs don’t need a DBA unless using a business name different from their formation certificate. Before filing, check the Secretary of State’s website to see if the desired name is available.

Registering a DBA in Illinois

To register a DBA in Illinois:

  • For sole proprietorships and general partnerships, search for an available business name with the Secretary of State or your county clerk. Then file the certificate of assumed name with your county clerk.
  • For LLCs and corporations, search the Secretary of State’s database to ensure the desired DBA name is available and meets requirements. Then file the assumed business name application.

Filing fees for DBAs depend on the year registered and business structure. Fees range from $30-150 for sole proprietorships and partnerships. For LLCs and corporations, fees vary by year.
