Illinois annual report filing for LLCs and corporations
Illinois LLCs file an annual report, Form LLC-50.1, with the Secretary of State before the first day of their anniversary month, every year. Corporations file their own annual report on the same anniversary cycle, together with Illinois franchise tax.

Who has to file the Illinois annual report?
LLCs
Every Illinois LLC files Form LLC-50.1, or the same report online, before the first day of its anniversary month: the month its articles of organization became effective.
Corporations
Illinois for-profit corporations file the Domestic Corporation Annual Report (Form BCA 14.05) before the first day of their anniversary month, and pay franchise tax computed on paid-in capital with it.
One Illinois quirk: a change of registered agent cannot ride along on the annual report. It takes Form LLC-1.36/1.37 or the Secretary of State’s separate online change application, so an agent switch and an annual report are two filings.
When is it due?
The deadline is the day before the anniversary month begins, not the end of that month. An LLC whose articles took effect in March must have its report in by the last day of February. Owners used to states that allow the whole anniversary month are the ones most often caught by it.
Where is it filed?
Reports go to the Illinois Secretary of State, Department of Business Services, either online or on Form LLC-50.1.
What happens if the Illinois annual report is late?
A late filing penalty applies if the report is not filed within sixty days after the due date. The Secretary of State then sends a notice of delinquency; an LLC that does not correct the default within 120 days of that notice is administratively dissolved. Corporations get 90 days rather than 120, and unpaid franchise tax is a ground for dissolution too.

How does LLCity file the Illinois annual report?
We file it for you, entity by entity, and keep the next date on your schedule. State fees are confirmed with you before anything is filed.
We date each Illinois entity from the month its articles took effect, and set the deadline at the end of the month before it.
For corporations, we collect the paid-in capital figure the report needs before the deadline, so the franchise tax is computed correctly.
We file each report with the Secretary of State and send you the filed copy.
If an agent or office change is due, we file it separately, because Illinois will not take it on the annual report.
Several Illinois entities?
Illinois dates each entity from its own anniversary, so a portfolio spreads across the year, and LLCs and corporations need different information. We keep both on one schedule and ask you only for what each report needs.
What else recurs in Illinois?
Every recurring Illinois filing on our compliance calendar, labelled by the entity it belongs to. Fees are set by the state and confirmed with you before anything is filed.
