STATE COMPANY GUIDE
Overview and reading notes
Illinois official navigation: Illinois Secretary of State Business Services. This department provides formation, registration and status services for LLCs, Corporations, LPs and LLPs; Illinois tax registration does not replace entity formation by the Secretary of State. The state's specific filing fees, expedited fees, document fields and processing times have not been individually verified here. Before filing, check the current state forms and fee schedule; figures from other states are not applied.
The following sections separately describe registration, annual reports, tax and account opening in state materials; company formation is not treated as equivalent to authorisation to conduct regulated financial business.
