What happens if I file my Illinois LLC annual report late?

Illinois gives you a short window past the deadline and then charges a penalty that compounds. Under Illinois law, the annual report is due before the first day of your LLC's anniversary month. If it is still not on file by the first day of the second month after that anniversary month, the law adds a $100 penalty on top of the $75 report fee, then another $100 for each year or fraction of a year beginning with the second year you stay delinquent. An LLC three years behind can owe $300 in penalties on top of $225 in unpaid report fees. An LLC that stays delinquent can be administratively dissolved by the Secretary of State, which ends its authority to carry on business other than winding up. Illinois law gives 120 days from the date of the notice of delinquency, after which the Secretary of State must dissolve the company. Reinstating an administratively dissolved Illinois LLC costs $200 under Illinois law, on top of the back report fees and penalties. File the overdue report through the Business Services section of ilsos.gov as soon as you notice the miss.

How do I file my Illinois LLC annual report?

File the annual report with the Illinois Secretary of State, Department of Business Services, either online at ilsos.gov or on paper. The fee is $75 either way, and a series LLC adds $50 for each series. Online filers pay by credit card or electronic check and get an immediate confirmation, which avoids mail delays. To file by mail, send the completed annual report form with a check payable to the Secretary of State to the Department of Business Services. Have your Illinois file number, registered agent name and address, principal place of business, and current member or manager details ready before you start. The report is due before the first day of your LLC's anniversary month under Illinois law, and the $100 statutory penalty attaches once you pass the first day of the second month after that anniversary month. The Illinois Secretary of State publishes no standard processing time for this filing, so file early rather than counting on same-day turnaround.

How much does it cost to file an Illinois LLC annual report?

The filing fee for an Illinois LLC annual report is $75, payable to the Illinois Secretary of State, and the amount is the same whether you file online through the Business Services portal or by mail. A series LLC pays $75 plus $50 for each series. Online filers can pay by credit card, debit card, or electronic check during the filing process; mail filers include a check or money order with the completed report sent to the Department of Business Services in Springfield. Treat the $75 as a recurring annual cost of keeping the LLC in good standing and file before the first day of your anniversary month. If the report goes past the first day of the second month after that anniversary month, Illinois law adds $100, plus another $100 for each year or fraction of a year from the second year of delinquency onward. Related filings are priced separately: a certified copy or a certificate of good standing costs $25, and reinstatement after administrative dissolution costs $200.

When is my Illinois LLC annual report due?

Illinois ties the deadline to your own formation date rather than one statewide date. Under Illinois law the annual report is due before the first day of your LLC's anniversary month, the month in which the Secretary of State accepted your articles of organization. If your LLC was formed in March, each year's report should be on file before March 1. Illinois does not penalize you the instant that day passes. The $100 penalty attaches only once you have failed to file before the first day of the second month after the anniversary month, so a March LLC reaches the penalty on May 1. Do not treat that later date as the deadline, because each additional year of delinquency adds another $100. The fee is $75 and the report is filed with the Secretary of State online or by mail through ilsos.gov. Check the file-stamped date on your articles of organization for the exact month, then set a recurring reminder for the month before it.

Are there any exemptions from filing Illinois LLC annual reports?

All active Illinois LLCs file an annual report with the Illinois Secretary of State every year, $75 plus $50 per series for a series LLC, before the first day of the anniversary month. There is no small-business, no-revenue, or first-year exemption. An LLC that has wound up and put articles of dissolution on record stops filing from that point forward. An LLC the Secretary of State has already administratively dissolved cannot file a standard annual report at all; it applies for reinstatement, which costs $200 under Illinois law, and pays the back report fees and penalties. Being dormant is not an exemption either: an inactive LLC that files nothing still picks up the $100 penalty once it passes the first day of the second month after its anniversary month, and another $100 for each year or fraction of a year from the second year on. Confirm your LLC's current status with the business entity search at ilsos.gov before assuming you owe nothing.

How do you file the Illinois LLC annual report?

Do You Need a Paid Service to File?

No. You can file this report yourself, using the filing method in the table above, and pay only the state's own fee shown there, with no service fee on top.

Hiring a registered agent service is a separate choice, and it is optional too. Every LLC must keep a registered agent, but in most states the LLC's owner, or another individual who qualifies, may serve as its registered agent themselves, generally subject to that state's rules on keeping a street address in the state and being available there during normal business hours. The Illinois registered agent requirements set out what Illinois itself asks.

Registered agent services for Illinois LLCs

Affiliate disclosure: Northwest Registered Agent, Bizee, ZenBusiness and LegalZoom pay us a commission if you sign up through our link, at no extra cost to you. We list only the registered agent services we have an affiliate relationship with, so this is not a survey of the whole market.

This list is not scored. The four are listed cheapest annual renewal first, and every claim below is about the services listed here rather than the whole market.

Northwest Registered Agent$125/yr renewal
Best for: Privacy-focused owners and anyone who just needs an agent, not a formation bundle
Bizee$149/yr renewal
Best for: A free first year (some visitors are being shown shorter free periods, so confirm at checkout), renewing at $149/yr, if you're comfortable with the BBB caveat
ZenBusiness$199/yr renewal
Best for: First-time founders forming a new LLC who want phone, email and chat support
LegalZoom$249/yr renewal
Best for: Complex structures that want attorney consultations, which come with LegalZoom's $299 formation plan (and, in one version of its plans, the $249 plan) rather than this renewal price

Note: Bizee holds a C rating from the BBB and is not accredited. BBB's profile carries a live alert describing a pattern of complaints about unexpected charges, difficulty canceling and filing delays, and Bizee has posted a response to it. We flag this so you can make an informed choice.

This guide is general information, not legal or tax advice, and reading it does not create an attorney-client relationship. It reports what each state publishes about filing deadlines, fees, and the consequences of missing them, with the sources this page cites. It cannot tell you what your own company owes: the date turns on when and where you formed, states change these rules between our reviews, and in several states an entity-level tax falls due in a year when no report does. Confirm your own dates with the filing office named on this page before you rely on one here, because missing a deadline can cost the company its good standing or, in many states, its existence.
