The Connecticut Annual Report
The centerpiece of ongoing compliance is the annual report, filed with the Secretary of the State. Nearly every Connecticut LLC has to file it, and it is what tells the state your company is still active and its information is current.
What the annual report is, and is not
The report is a status update, not a financial disclosure. You are confirming or updating:
- Your LLC's name and your principal office and mailing addresses.
- At least one member or manager.
- Your registered agent.
- Your business email address and NAICS industry code.
The state fee is $80. You are not reporting revenue, profit, expenses, or any financial figures. It is a short, informational filing whose purpose is to keep the state's public record on your LLC accurate.
Connecticut's online-only rule
Here is the Connecticut-specific detail that trips people up: by statute the annual report is filed by electronic transmission, through Business.CT.gov, and a paper exemption is granted only on request for good cause. You log in (or create an account) and select "File annual report." The state does not accept a paper annual report. If you are used to mailing forms, this one is different. There is no paper path. Everything goes through the Business One Stop portal.
The Deadline and How the Window Works
Connecticut gives you a defined window each year rather than a single due date scattered across the calendar.
When it is due
Your first report is due the year after your LLC is formed. From then on, the filing window opens January 1 and closes March 31 every year, and you can file any time inside it. The state emails the address you provided about a month before the report is due (or mails a postcard if it has no email). Because the deadline is the same for all LLCs rather than tied to your formation anniversary, it is easy to set a recurring reminder and knock it out early in the year.
Why filing early is smart
There is no advantage to waiting until late March, and there is a real downside: portal issues, forgotten passwords, or a busy week can push you past the deadline. Filing in January or February gives you margin. If something goes wrong, you have time to fix it before March 31 rather than scrambling at the last minute.
Set a system, not just a memory
The most reliable owners do not rely on remembering. They put a January reminder on the calendar every year, or they use a service that tracks the window for them. Because the report is annual and the date is fixed, a simple recurring reminder is enough to never miss it.
What Happens If You Miss It
Missing the annual report is not a minor slip, even though Connecticut charges no late fee for it. The consequences build the longer it goes unaddressed.
No Certificate of Legal Existence
The Secretary of the State is direct about the first consequence: if your annual report is overdue, you can't get a Certificate of Legal Existence. That is the document banks, lenders, buyers, and other states ask for as proof your LLC is in good standing, so an overdue report can stall a loan, a contract, or a foreign registration.
Dissolution by forfeiture
Under section 34-267g, once an LLC is more than one year in default, the Secretary may email a notice that its rights and powers are prima facie forfeited. Unless the report is filed within three months of that notice, the LLC is dissolved by forfeiture. A dissolved LLC has lost its active status and can't carry on business except to wind up.
Reinstatement
Reinstatement after forfeiture is possible, but it is a real filing: a certificate of reinstatement ($120), the consent of a majority in interest of the members, an annual report for the current year, any penalties, and an agent appointment. The math always favors keeping current: the annual report is a predictable $80, while reinstatement is a larger, avoidable cost.
Other Ongoing Obligations
The annual report is the headline, but a few other things need to stay current for the LLC to remain genuinely compliant.
Keep your registered agent valid
Your registered agent must remain valid for the life of the LLC: a Connecticut resident or a business entity registered in Connecticut. If the agent moves, resigns, or is no longer available, file a Change of Agent ($50) so the record shows a valid agent. An outdated agent leaves the LLC technically non-compliant and risks missed legal documents, even if your annual report is current.
Keep addresses accurate
If your principal office or mailing address changes, update it. The annual report is the routine place to do this, but if a change happens mid-year and matters for receiving mail, keep the record correct.
Stay current on taxes
Compliance with the Secretary of the State is separate from tax compliance. Connecticut taxes pass-through income at the member level, offers a Pass-Through Entity Tax through the Department of Revenue Services that has been elective since January 1, 2024, and collects sales and use tax if you sell taxable goods or services. Federal filings follow your tax structure: Schedule C, Form 1065, or an S-corp return. Being in good standing with the state does not mean your taxes are handled; those are their own obligations.
Maintain your internal records
Connecticut does not require you to file an operating agreement, but keeping one current (updating it when ownership, management, or contributions change) is part of running the LLC properly and preserving the liability shield.
How Mainstay Filing Keeps You Compliant
For owners who would rather not track the window themselves, we monitor your annual report deadline and can prepare and file the report for you inside the January 1 to March 31 window, using the current information on file. Because we serve as your registered agent, we also keep that piece valid and catch the state notices that flag any compliance issue.
The value here is not complexity: the annual report itself is simple. The value is never missing it. A single forgotten year can start the slide toward dissolution by forfeiture and reinstatement costs, and a reminder-and-file service exists precisely so that never happens. We are a filing and agent service, not a tax preparer or law firm; your income and sales tax filings still go through your accountant, and legal questions still go to an attorney. What we own is the Secretary of the State compliance calendar, so your LLC stays in good standing year after year.
Frequently asked questions
When is the Connecticut LLC annual report due?
The filing window runs from January 1 through March 31 each year. You can file any time inside that window. The deadline is the same for every Connecticut LLC rather than tied to your formation date, which makes it easy to set a fixed annual reminder. Filing early leaves margin in case of portal or login issues.
Can I file the Connecticut annual report by mail?
No. Connecticut's annual report is online-only, filed through Business.CT.gov. The state does not accept a paper version. This is a common surprise for owners used to mailing forms. There is no paper path for this particular filing.
What happens if I miss the annual report deadline?
There's no late fee, but you can't get a Certificate of Legal Existence while the report is overdue. Once the LLC is more than a year in default, the state may email a forfeiture notice, and if you don't file within three months, the LLC is dissolved by forfeiture. Reinstating it takes a $120 certificate plus the current report, so keeping current is always the cheaper path.
Is the annual report a tax filing?
No. It is a compliance filing that updates your registered agent, addresses, and management information with the Secretary of the State. It reports no financial figures. Your federal and Connecticut tax returns are entirely separate obligations filed with the IRS and the Department of Revenue Services.
What else do I have to keep current besides the annual report?
Keep a valid registered agent (a Connecticut resident or a registered business entity) at all times, keep your principal and mailing addresses accurate, and stay current on your federal and Connecticut taxes. Maintaining an up-to-date operating agreement is also good practice. Being in good standing with the Secretary of the State does not cover your tax obligations. Those are separate.
