Illinois Is Due on the First of the Month
Most anniversary states give you the whole month. Illinois gives you none of it. The Annual Report is due on the first day of the entity's anniversary month, which means an LLC organised on 20 June has a June 1 deadline, three weeks before the date it thinks of as its birthday. Owners who assume the ordinary month-end pattern file on the 20th, discover a $100 penalty waiting, and cannot understand what they did wrong. Nothing about the anniversary date is wrong; the assumption about which end of the month counts is.
The filing goes to the Illinois Secretary of State through the Department of Business Services portal at apps.ilsos.gov. It confirms the entity name and file number, the principal office, the registered agent and registered office address in Illinois, and the managers or officers and directors required for the entity type. A corporation also reports the information Illinois uses for its franchise tax calculation, which is why the corporate cost of the annual report sits at $100 while an LLC pays $75.
Who files and what the form carries
Every domestic LLC and corporation on the Illinois register files, as does every entity foreign-qualified to do business in the state. The report is the only routine opportunity Illinois gives you to correct the register without a separate filing, so the officer list, the manager list and the principal office all belong in it. Anything the report cannot carry, such as the legal name itself, needs an amendment first; the boundary is set out in our Illinois amendment guide. The registration route for out-of-state entities is covered in the Illinois foreign qualification guide.
The shortest dissolution clock in the region
Illinois moves to administrative dissolution after 18 months of non-compliance. Neighbouring states run 24 or 36. Eighteen months means an entity that misses one report and then misses the next is already inside the dissolution window, without ever having skipped two full calendar years of trading. Combined with a $100 penalty that attaches immediately and interest that runs on top, Illinois is the least forgiving state in this group on both the money and the clock.
Fee, Deadline and What the Portal Validates

| Item | Value |
|---|---|
| Report name | Annual Report |
| Filing frequency | annual |
| Deadline | First day of the anniversary month |
| LLC filing fee | $75 |
| Corporation fee | $100 |
| Late penalty | $100 + interest |
| Processing time | 5-10 business days |
| Filing agency | Illinois Secretary of State |
The penalty is larger than the LLC fee and equal to the corporate one. In practical terms an Illinois filer who is one day late pays more than double, and unlike most states the arrears keep growing because interest runs alongside the flat charge. Illinois is one of the few places where the honest advice is to file the report even if you are unsure about a detail, because a corrected filing later costs nothing while a late one costs $100.
Processing and the practical cutoff
Standard processing runs 5 to 10 business days. Because the deadline is the first of the month, a filer aiming for the deadline is really aiming for the middle of the preceding month. An entity with a September anniversary should be submitting in the third week of August, not in the first days of September. That two-week shift, applied to a deadline that already sits a month earlier than most people assume, is the single most useful correction an Illinois filer can make.
File your annual report
If you would rather not do this yourself, we pull your record from the state, prefill every field, and track the deadline for next year. Or keep reading and file it on your own. This guide covers everything you need either way.
Penalties and the Illinois Dissolution Clock
Illinois is the state in this group where the arithmetic of a lapse becomes serious fastest, because the penalty is large, interest accrues, dissolution arrives at 18 months and reinstatement requires the Department of Revenue to sign off.
One, two and three missed years in dollars
For an LLC each missed year carries the $75 report and the $100 penalty, so one missed year clears at $175, two at $350 and three at $525, before interest. For a corporation each missed year carries the $100 report and the $100 penalty, so one clears at $200, two at $400 and three at $600, again before interest. Add the $200 Application for Reinstatement once the entity has been dissolved and a three-year LLC lapse settles at $725 in state charges, a corporate one at $800. Interest runs on top of both, and neither figure includes the accounting needed to satisfy the tax clearance requirement.
What you lose before you lose the entity
The delinquent flag appears on the public record well before dissolution, and the Illinois Certificate of Good Standing stops being available while a report is outstanding. That certificate costs $25 on standard handling with 5 to 10 business day turnaround, or $50 expedited in 1 to 2 business days, and Illinois issues it with the entity's franchise tax status shown on the face of the document, which makes it unusually informative to the counterparty reading it. A blocked certificate in Illinois therefore tells a buyer or a lender more than a blocked certificate elsewhere would. Details are in the Illinois Certificate of Good Standing guide.
Reinstatement and the Revenue Department
After administrative dissolution Illinois allows 60 months to reinstate. The Application for Reinstatement costs $200 and takes 10 to 20 business days, which is the longest processing window of any filing described here. The expensive part is not the fee. Illinois requires tax clearance before it restores an entity, so every dormant year has to be reported and settled with the Department of Revenue first, including years with no activity at all. Our Illinois reinstatement guide sets out the sequence, the reinstatement service handles the filing at a fixed $249 in service fees, and the Illinois dissolution guide covers closing deliberately, which is materially cheaper than lapsing.
Three Illinois Filings in Practice
Example 01: a Chicago single-member LLC
A freelance UX researcher organised a single-member LLC in Chicago on 22 April, which gives her an April 1 deadline every year rather than an April 22 one. Action taken: after a first year in which she nearly filed three weeks late, she moved the reminder to March 10, confirms her registered agent's Cook County street address, confirms herself as sole manager, and submits. Real cost: $75 to the Secretary of State. Timeline: eight minutes on the portal, accepted six business days later. Outcome: current for the year, with $100 in penalty avoided by the calendar change alone.
Example 02: a Naperville corporation changing its officers
A Naperville engineering corporation with nine shareholders replaced its president in September and added a second vice president in January. Illinois collects both changes on the annual report rather than through a separate officer filing. Action taken: the report filed in the third week of January, ahead of a February 1 deadline, listed the incoming president, added the vice president, removed the outgoing officer, and updated the registered office to the firm's new suite. Real cost: $100, the corporate annual report fee, with no separate charge for the officer changes. Timeline: filed January 19, accepted January 27. Outcome: the register matches the board consent on file, which is what the corporation's surety examined before renewing its bonding line.
Example 03: a foreign-qualified LLC filing in three states
A commercial signage LLC formed in Illinois qualified in Indiana and Wisconsin as its installation work spread across the state line. The three states use three different clocks. Action taken: the owner recorded Illinois at $75 due on the first day of the anniversary month, Indiana at $32 due in the anniversary month but only every second year, and Wisconsin at $25 due at the end of the anniversary quarter. Real cost: $100 in most years and $132 in the years the Indiana Business Entity Report falls due. Timeline: roughly 30 minutes a year. Outcome: no lapse in any state, and the biennial Indiana filing stopped disappearing in the years it was not due. The cross-state picture is in .
Five Mistakes on the Illinois Annual Report
Mistake 1: Filing only when the notice arrives
What it is: using the Secretary of State reminder as the trigger to act. Why it happens: the reminder normally arrives, and for several years the system appears to work. Consequence: notices follow the address on the register, so a stale address silently ends the reminders, and in Illinois the first missed cycle costs $100 plus interest rather than a token penalty. Prevention: calendar the first day of the anniversary month yourself, with an alert in the middle of the preceding month, and treat the state notice as confirmation only.
Mistake 2: Assuming the deadline is the end of the anniversary month
What it is: filing during the anniversary month because that is how most anniversary states work. Why it happens: Illinois is the exception, and exceptions are learned the expensive way. Consequence: a filing made on the anniversary date itself is up to a month late, and the penalty attaches even though the owner filed inside what they believed was the window. Prevention: write the rule as first day of the anniversary month in every calendar entry, and never store the deadline as the anniversary date.
Mistake 3: Confirming a registered office that has moved
What it is: accepting the prefilled registered agent and registered office because they were right last year. Why it happens: the portal presents the existing record and confirming is faster than verifying. Consequence: Illinois treats service delivered to the registered office as good service whether or not anyone is there to receive it, so a lapsed office address turns into a default judgment against a business that never saw the claim. Prevention: confirm the agent still consents and still holds an Illinois street address, and file a change of registered agent when it is wrong. The requirement is set out in the Illinois registered agent guide.
Mistake 4: Assuming a dormant year needs no report
What it is: skipping the report because the entity did not trade, or because an owner expects a fee waiver for a dormant company. Why it happens: several states charge nothing for a dormant filing, and the instinct travels. Consequence: Illinois charges the full $75 or $100 regardless of activity, adds $100 when the report is late, and dissolves at 18 months, which is faster than a dormant company usually gets around to noticing. Prevention: file the report every year the entity exists, and if it will not be used again, close it deliberately rather than letting it lapse.
Mistake 5: Waiting for an initial report Illinois does not require
What it is: expecting a separate first filing within 90 days of formation before the annual cycle begins. Why it happens: neighbouring and comparable states do impose one, and formation checklists written for a national audience mention it. Consequence: Illinois has no initial report, so the first obligation is the annual report on the first day of the first anniversary month, and an owner waiting for a first-year notice simply misses it. Prevention: on the day formation is approved, calculate the first anniversary month and diarise its first day. Forming the entity is covered in how to start an Illinois LLC.
Building an Illinois Filing Routine
Practice 1: Work a month ahead of the anniversary
Set the reminder for the middle of the month before the anniversary month. That covers the 5 to 10 business day processing window and leaves room for one rejection and refile before the first of the month. In Illinois that buffer is worth $100 plus interest every time it is used.
Practice 2: Reconcile the record before you confirm it
Check the registered agent's consent and Illinois street address, the principal office, the manager or officer list and the exact entity name against the formation document. Illinois validates hard on the name and the file number, and a mismatch discovered on the last working day before the first of the month cannot be fixed in time.
Practice 3: Keep the Illinois record together
Hold the file number, filed reports, franchise tax correspondence, the registered agent agreement and the current certificate in one place. Illinois puts franchise tax status on the face of its certificates, so the tax and register records need to agree before anyone else reads them. Our compliance monitoring watches that status, and the annual report filing service handles the submission.
How File.Business Handles Illinois Annual Reports
File.Business files the Illinois Annual Report for entities on our compliance service. We take the anniversary from the register and set the deadline to the first of that month rather than the last, pull the current record from the Department of Business Services so the submission matches, surface anything that needs an amendment or a registered office change first, file ahead of the deadline, pay the $75 or $100 state fee, and confirm acceptance. Given an 18-month dissolution clock and a $100 penalty that begins accruing interest immediately, Illinois rewards the buffer more than any other state in this group. Illinois registered agent service and good-standing monitoring are included. Scope and pricing are on the Illinois annual report page.
Illinois annual report FAQ
When is the Illinois annual report due?
On the first day of the entity's anniversary month, not the last. An LLC organised on 20 June has a June 1 deadline every year. Filing during the anniversary month rather than before it is late, and a $100 penalty plus interest attaches immediately.
How much does the Illinois annual report cost?
The Illinois Annual Report fee is $75 for LLCs and $100 for corporations. Payment is made in the Department of Business Services portal at the time of filing. Late filings add a $100 penalty plus interest, which is more than the LLC fee itself.
Where do I file the Illinois annual report?
Online at apps.ilsos.gov, the Illinois Secretary of State Department of Business Services portal. Standard processing runs 5 to 10 business days, so an entity with a September anniversary should be submitting in the third week of August rather than in early September.
What happens if I miss the Illinois deadline?
A $100 penalty plus interest attaches and the entity is flagged delinquent, which blocks the $25 Certificate of Good Standing. Three missed years cost an LLC $525 and a corporation $600 before interest. Illinois administratively dissolves after 18 months, the shortest clock in the region, and reinstatement then costs $200 and requires Department of Revenue tax clearance.
How long does Illinois allow for reinstatement?
Sixty months from administrative dissolution. The Application for Reinstatement costs $200 and takes 10 to 20 business days once filed, but the tax clearance requirement usually sets the real timetable, because every dormant year has to be reported and settled with the Department of Revenue before the Secretary of State will restore the entity.
Do foreign LLCs need to file an Illinois annual report?
Yes. An LLC or corporation foreign-qualified in Illinois files the annual report on the same first-of-the-anniversary-month schedule as a domestic entity, at the same fee. The report filed in your formation state does not satisfy the Illinois requirement.
Can File.Business file my Illinois annual report?
Yes. We set the deadline to the first of the anniversary month, validate every field against the Department of Business Services record, file ahead of the deadline, pay the $75 or $100 state fee and confirm acceptance. Illinois registered agent service and good-standing monitoring are included with the compliance service.
