Connecticut LLC Annual Report: Due Date, Fee and Late Penalty

Connecticut LLC annual report rules at a glance

State fees verified October 2026 and set by the state, not by us. Deadlines, penalties and dissolution rules are Connecticut's, read from its statutes and the pages of the Connecticut Secretary of the State; the statutes are cited in the text.

How Connecticut's annual report works

Connecticut gives every LLC the same window: the annual report is filed with the Secretary of the State between January 1 and March 31 each year, whatever the formation date, through the business.ct.gov portal with a CT.gov account. Corporations in Connecticut run on their own anniversary dates, but for an LLC the March 31 date is fixed.

The state fee is $80, the same for a domestic or a foreign LLC (Connecticut's corporation reports cost more). The report confirms the principal office and mailing address, the registered agent, and the name and address of at least one member or manager, and it asks for the LLC's NAICS code and an email address for state notices.

Connecticut charges no late fee on an LLC annual report. The Secretary of the State's own FAQ answers the question directly: there is no additional fee or penalty for filing after the due date. What Connecticut does require is order: a past-due report can only be filed once every earlier year's report has been filed first.

Who files it and what the form asks

Every Connecticut LLC on the state's active record owes the annual report for each report year, whether or not it did any business; an LLC that has stopped trading still owes it until it files articles of dissolution. A member, manager or someone they authorize signs it, and in practice the owner, the registered agent or the company's accountant files it.

The form confirms what the state already holds: the principal office and mailing address, the registered agent and registered office, and the people who run the LLC, with the Connecticut-specific fields described above. What matters is that anything that changed during the year is corrected here, because the state sends its notices, including the next year's reminder, to the addresses on the report.

Changing the registered agent is best treated as a separate filing in Connecticut: the annual report confirms the agent on record, and the state's statement of change names the new one. Owners who switch agents usually file the change first so the report shows the right agent. We can make the switch for you, and the Connecticut registered agent rules cover who may serve. Every state's change form and fee is in how to change a registered agent.

When the Connecticut annual report is due

Connecticut uses one date for every LLC: March 31, every year. The state starts accepting the report on January 1, so the filing window runs from then to the due date, and filing in the first weeks of it is the simplest way never to meet the penalty.

There is no grace period: the day after the due date the report is late. Connecticut keeps accepting that year's report through December 31 of the report year; after that the consequences below take over.

Your first annual report

The first annual report is due March 31 of the year after the LLC was formed: formed any time in 2026, first report by March 31, 2027. Nothing is owed in the formation year itself.

The state fee and the late penalty

The state fee is $80 a year. It is set by Connecticut and published on the state's own schedule; anyone who files for you pays the same amount to the state, and the state fee is shown separately wherever the filing is sold.

Connecticut charges no late fee. That does not make the deadline soft: the state's response to a missed report is the status change and dissolution process described next, not a fee, and a reinstatement costs more than the report ever did.

If you missed the Connecticut annual report

A Connecticut LLC that leaves its report unfiled is administratively dissolved by the Secretary of the State after notice; the state's record shows one missed report is enough. Connecticut's reinstatement is a single flat filing, $120 in state fees, that already includes the annual report the state requires with it, so unlike Florida the cost does not grow with the years missed. A Certificate of Legal Existence ($50 state fee) is the document a bank asks for afterwards.

The ladder is the same everywhere: a late fee where the state has one, then loss of good standing (which blocks a certificate of good standing and the loans, contracts and registrations that need one), then administrative dissolution or revocation, then reinstatement. Our guide to reinstating a dissolved LLC walks through the steps and the state fees in every state, and we file reinstatements. Until the LLC is dissolved, the cheapest fix is almost always to file the report now.

Before you file the Connecticut annual report

The filing itself takes minutes once the details are to hand; most of the time lost on an annual report is spent hunting for them. Have ready:

• The LLC's Connecticut file or entity number, as it appears on the articles or on the Connecticut Secretary of the State business search; the Connecticut Secretary of the State requires an online account tied to the record, so set that up before the deadline week.
• The registered agent's current name and Connecticut street address; if the agent has changed, file the change first.
• The principal office and mailing address as they should read for the coming year.
• The names and addresses the Connecticut form asks for (above), spelled as the state has them.
• A card for the $80 state fee.
• The signer's name and capacity: member, manager or authorized person.

Save the state's confirmation when it arrives. It is the proof of filing a bank, a lender or a buyer will ask for, and the date on it is the date the state goes by.

How Connecticut compares with its neighbors

Connecticut's annual report is due March 31, with a state fee of $80. Next door:

• New York: a biennial statement due the last day of the anniversary month ($9 state fee, no late fee).
• Massachusetts: an annual report due the anniversary date of formation ($520 state fee, no late fee).
• Rhode Island: an annual report due May 1 ($50 state fee, $25 late penalty).

An LLC registered to do business in more than one of these states owes each state's report on each state's calendar; the formation state's filing never covers a foreign registration, and the due dates rarely line up.
