How to File
1
Access the Connecticut Business Services Portal
Start at business.ct.gov/business-services, the Secretary of the State's Business Services home. The older portal.ct.gov/sots address now redirects there. Have your LLC's business ID and current company details ready before you begin.
2
Complete the Annual Report
Confirm your LLC's name, principal office address, mailing address, registered agent details, and the names and addresses of your managers or members. Conn. Gen. Stat. 34-247k(a) requires the report to be delivered by electronic transmission, so filing online is the standard route. Paper filing is allowed only if the Secretary of the State grants an exemption for lack of capability or other good cause.
3
Pay the $80 Filing Fee
The fee is $80 per year under Conn. Gen. Stat. 34-243u(a)(15)(B), for both domestic LLCs and registered foreign LLCs. It was only $20 for report years before July 1, 2020, so older cost guides understate it. Pay through the portal and keep the confirmation.
4
Review and Submit
Check every field before you submit, because the annual report is the record the state and third parties rely on for your registered agent and principal office. Once accepted, the filing appears in the Secretary of the State's business records search.
5
Maintain Records
Save the filing confirmation with your LLC records and set a reminder for the next window, which opens January 1 and closes March 31. If your LLC was formed this calendar year, your first report is not due until that window in the following year.

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
Connecticut charges no late fee. Neither Conn. Gen. Stat. 34-243u nor the Secretary of the State's fee schedule provides any penalty for a late LLC annual report, so the fee stays $80 whenever you file it. The consequence of not filing is forfeiture rather than a fee. Under Conn. Gen. Stat. 34-267g, once an LLC is more than one year in default of filing its annual report, the Secretary may send electronic notice that the company's rights and powers are prima facie forfeited. If the report is still not filed within three months of the sending of that notice, the Secretary files a certificate of dissolution by forfeiture. Before that point, a delinquent LLC also loses its certificate of legal existence and good standing, which is what banks, lenders, and counterparties usually ask to see. Getting a forfeited LLC back costs $120 for a Certificate of Reinstatement, plus the $80 reports you missed. If you are behind, file the outstanding report at business.ct.gov/business-services now rather than waiting for a notice.
File through the 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 filing is the normal route; paper is available only if the Secretary of the State grants an exemption for lack of capability or other good cause.
The report asks you to confirm your LLC's name and business ID, principal office address, mailing address, registered agent name and address, and the names and addresses of your managers or members. The fee is $80, the same for domestic LLCs and registered foreign LLCs.
The filing window runs after January 1 and before April 1 each year, which makes March 31 the last day. Connecticut charges no late fee, but an LLC more than one year in default can be dissolved by forfeiture under Conn. Gen. Stat. 34-267g.
Filing online takes only a few minutes and gives you immediate confirmation. Save it with your records.
$80 a year, paid to the Connecticut Secretary of the State. Conn. Gen. Stat. 34-243u(a)(15)(B) sets that amount for any report year on or after July 1, 2020, and business.ct.gov confirms the same $80 for domestic and registered foreign LLCs alike. Before July 2020 the fee was $20, which is why older guides and forum posts quote a much smaller number. There is no separate late fee, so a report filed after the deadline still costs $80. There are also no exemptions, discounts, or reduced rates based on revenue or activity. What non-filing costs is your standing: an LLC more than one year in default can be dissolved by forfeiture, and a Certificate of Reinstatement is $120 on top of the missed $80 reports. For most Connecticut LLCs the $80 report is the only recurring state charge, since the old $250 biennial Business Entity Tax was repealed. Budget $80 each January and file before March 31 at business.ct.gov/business-services.
Connecticut's annual report is due after January 1 and before April 1 of each calendar year, so March 31 is the last day to file. The window is the same for every LLC regardless of the month it was formed. The first report follows the same window one year later: Conn. Gen. Stat. 34-247k(c) provides that the first annual report must be filed after January 1 and before April 1 of the year following the calendar year in which the LLC was formed, so an LLC formed at any point in 2026 files its first $80 report between January 1 and March 31, 2027 and owes no report in 2026 itself.
The fee is $80, and Connecticut charges no late fee if you miss the date. What a missed report risks is standing: the LLC loses its certificate of legal existence and good standing, and under Conn. Gen. Stat. 34-267g an LLC more than one year in default can be dissolved by forfeiture three months after the Secretary sends notice.
Set a calendar reminder for early March so you have time to confirm your registered agent and member details.

No. Every LLC on the Connecticut Secretary of the State's active records files an annual report each year, domestic and registered foreign alike, and there are no exemptions based on size, revenue, or activity. A dormant LLC that earned nothing still files to keep its certificate of legal existence and good standing.
The $80 fee is owed whatever the LLC's operating status, and it does not change if you file late, because Connecticut has no late fee. The obligation ends only when the LLC itself leaves the active rolls, either through a voluntary dissolution filing or through dissolution by forfeiture under Conn. Gen. Stat. 34-267g after more than a year in default. Forfeiture is not a shortcut, since a Certificate of Reinstatement costs $120 plus the missed reports.
One exemption does exist, but it is about method rather than obligation: Conn. Gen. Stat. 34-247k(a) requires electronic filing, and the Secretary of the State can excuse that for a filer who lacks the capability or shows other good cause. File at business.ct.gov/business-services before March 31.
