When the Illinois Annual Report is due

Illinois LLCs file an Annual Report every year. It is due before the first day of the LLC's anniversary month each year (the month it was formed).

What the Annual Report asks for

It confirms or updates what the state holds about your LLC. Expect to give:

  • The LLC's name and Illinois file number
  • The principal office and mailing address
  • Your registered agent's name and address in Illinois
  • The members or managers, as your state's form asks

If something has changed since the last filing, such as a new member or manager, update your operating agreement first so the two match.

If you miss it

The LLC falls out of good standing on Illinois's records. Most states also add a late penalty, and many administratively dissolve an LLC whose report stays unfiled. Without good standing, banks and partners ask questions, some contracts cannot be signed, and a dissolved LLC has to file for reinstatement. The sources below set out exactly what Illinois does.

State tax on Illinois LLCs

Illinois follows the federal classification: an LLC taxed as a partnership files Form IL-1065 and pays Personal Property Replacement Income Tax on its Illinois net income; an LLC taxed as a corporation files IL-1120 (or IL-1120-ST for an S corporation); a single-member disregarded LLC has no separate Illinois return

How to file

File with the Illinois Secretary of State, Department of Business Services, online. Have your file number and your current agent and address details ready.
