Illinois Annual Report: deadline, fees, and what happens if you miss it
When it's due
Due every year before the first day of the entity's anniversary month (first report due the year after formation).
What it costs
$75 for LLCs; corporations pay $75 plus franchise tax.
If you miss it
Late filings add penalties, and continued failure leads to administrative dissolution — after which the entity can't legally transact business or defend its name in Illinois.
Worth knowing
Illinois doesn't publish standing through automated registry checks — put the anniversary month on the calendar, or let StandingChecker track it.
