Connecticut LLC Annual Report: Due Date, Fee and What Happens If You Miss It

How the Annual Report works in Connecticut

Connecticut LLCs file an annual report with the Secretary of the State every year between January 1 and March 31, for $80. That fixed first-quarter window has applied to LLCs since 2018, so owners who remember the older anniversary-month rule, which still applies to Connecticut corporations, often file at the wrong time. The report is online only through a Business.CT.gov account, and it asks for more than many states: a six-digit NAICS code, a business email address, the registered agent's acceptance details, and the name, business address and residence address of at least one member or manager. The Secretary of the State emails a reminder about a month before the due date. There is no entity-level tax with it, since the old $250 business entity tax was repealed. The real risk of skipping it is dissolution by forfeiture once the LLC is a year behind.

First report: A new LLC files its first annual report in the January 1 to March 31 window of the year after it is formed; the Business Inquiry screen shows the assigned first due date.

Next statewide deadline after October 30, 2026: March 31, 2027. If a deadline falls on a weekend or holiday, check whether Connecticut moves it to the next business day.

If you miss the deadline

• The Secretary of the State does not list a separate late fee for LLC annual reports; the consequence of not filing is dissolution by forfeiture.
• Once an LLC is more than one year in default of its annual report, the Secretary of the State may email a notice that its rights are presumptively forfeited; if the report is not filed within three months of the notice, a certificate of dissolution by forfeiture is filed and the LLC is dissolved (C.G.S. 34-267g). Without a current report the LLC also cannot obtain a Certificate of Legal Existence.
• Fixing a dissolved or forfeited LLC is covered in our Connecticut LLC reinstatement guide.

How to file the Connecticut Annual Report

• Online only: log in to a Business.CT.gov account, search for the LLC by name or Business ID (ALEI), and file and pay by card. The report requires a six-digit NAICS code and a business email address.
• What becomes public: The report lists the principal office and mailing address, the registered agent, and the name, title, business address and residence address of at least one principal (member, manager or managing member).
• Filed or paid alongside it: No entity-level tax is paid with the report. Connecticut's former $250 biennial business entity tax was repealed by Public Act 19-117 and is not billed for 2019 and later periods.

What Connecticut charges over five years

Counts only the formation fee and the Annual Report fee. No entity-level tax is paid with the report. Connecticut's former $250 biennial business entity tax was repealed by Public Act 19-117 and is not billed for 2019 and later periods. Registered agent service, if you use one, typically adds $100 to $300 a year.

Mistakes Connecticut owners make

• Filing in the anniversary month, as Connecticut corporations do, instead of the January 1 to March 31 window that applies to LLCs.
• Trying to mail a paper annual report, when Connecticut accepts LLC annual reports only online.
• Leaving out the six-digit NAICS code or a principal's residence address, both of which the report requires.
• Paying a third-party solicitation that charges well above the $80 state fee for a report the owner can file directly.
