Connecticut LLC compliance in 2026: the $80 annual report due between January 1 and March 31, registered agent rules, the repealed entity tax, and filing steps.
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 the penalty for missing a deadline can be administrative dissolution of the company.
Frequently Asked Questions
Nothing is added to the bill. Connecticut charges no late fee on a delinquent LLC annual report, and neither Conn. Gen. Stat. 34-243u nor the Secretary of the State's fee schedule provides a penalty, so the report still costs $80 whenever you file it.
What you lose in the meantime is standing. A delinquent LLC cannot get a certificate of legal existence and good standing, which is the document banks, lenders, landlords, and counterparties routinely ask to see. Left alone, it escalates: under Conn. Gen. Stat. 34-267g, once an LLC is more than one year in default the Secretary may send electronic notice that the company's rights and powers are prima facie forfeited, and if the report is still not filed within three months of that notice the Secretary files a certificate of dissolution by forfeiture.
Restoring a forfeited LLC costs $120 for a Certificate of Reinstatement, plus each $80 report you skipped.
File the outstanding report at business.ct.gov/business-services as soon as you notice the gap. Because there is no penalty, catching up costs only the fee itself.
File through the Connecticut Secretary of the State's Business Services portal at business.ct.gov/business-services. The older portal.ct.gov/sots address redirects there. Conn. Gen. Stat. 34-247k(a) requires the report to be delivered by electronic transmission, so online is the normal route, with paper available only under an exemption granted by the Secretary of the State. Log in, open your LLC by its business ID, and confirm the principal office address, mailing address, registered agent name and address, and the names and addresses of your managers or members. The fee is $80, paid during submission, and the portal confirms the filing immediately. The window is the same for every Connecticut LLC: after January 1 and before April 1, so March 31 is the last day, regardless of the month you formed the company. If your LLC was formed this calendar year, your first report is not due until that window next year. Save the confirmation with your records, since the annual report is what keeps your LLC eligible for a certificate of legal existence and good standing.
Yes. You can act as your own registered agent for a Connecticut LLC if you have a Connecticut street address, not a P.O. box, and are there during business hours to accept service of process. Consider what that means in practice. Lawsuits, state notices, and tax correspondence come to you personally, and a summons that is delivered but not acted on can turn into a default judgment. Your address also becomes part of the public record, which matters if you work from home. Connecticut's $120 Certificate of Organization fee already covers the appointment of your registered agent at formation, and changing agents later is a separate filing with the Secretary of the State. Many owners hire a commercial registered agent service, typically around $125 a year, for reliable receipt of documents, a business address on the public record, and someone tracking the January to March report window. If you cannot count on being at a Connecticut address during business hours, use a service.
About $200 in state fees. The Certificate of Organization is $120 under Conn. Gen. Stat. 34-243u(a)(3), the same amount whether you file online or on paper, and that fee includes appointment of your registered agent. The $80 annual report follows, and the timing matters: Conn. Gen. Stat. 34-247k(c) puts the first report in the window after January 1 and before April 1 of the year following the calendar year in which the LLC was formed, so an LLC formed in 2026 pays $120 in 2026 and its first $80 report between January 1 and March 31, 2027. That $200 total sits about $32 below the national average, though 28 states are cheaper still. Optional extras are real but avoidable: 24-hour expedited service is $50 per transaction and online only, a name reservation is $60, a certified copy is $55, a certificate of existence is $50, and a commercial registered agent runs around $125 a year. There is no publication requirement and, since Public Act 19-117 repealed the Business Entity Tax, no separate entity-level tax to budget for. File at business.ct.gov/business-services and set a reminder for the January to March window.
