Ready to file your annual report?
Go directly to the Connecticut Secretary of State portal.
Connecticut imposes a $25 late fee for annual reports filed after March 31st with the Connecticut Secretary of the State. If your LLC misses this deadline, you must file Form LLC-1.1 (Annual Report) and pay both the standard $150 filing fee and the $25 penalty fee, totaling $175.
Continuing non-compliance triggers administrative dissolution proceedings initiated by the Secretary of the State. Once dissolved, your LLC loses good standing status, meaning you cannot legally conduct business in Connecticut, enter contracts, or sue in state courts. The state may also assess additional penalties and interest charges.
Critically, creditors and customers may view your dissolved status as grounds to challenge your liability protections, potentially exposing your personal assets to claims.
File Form LLC-1.1 immediately with the Secretary of the State's office at www.ct.gov/sots, even if late, to halt dissolution proceedings and restore compliance status.
Connecticut LLCs must file their annual report through the Connecticut Secretary of State's online portal at sos.ct.gov. Log in with your business credentials and complete Form LLC-1065, providing current registered agent information, principal place of business, and member details. The $80 filing fee is non-refundable and must be paid via credit card through the secure portal during submission. Your report is due by the last day of the month in which your LLC was formed—missing this deadline triggers a $25 monthly penalty and potential administrative dissolution. The portal generates immediate confirmation once payment processes successfully. This annual filing maintains your LLC's good standing status and legal protection for members. Complete your 2026 filing immediately by logging into the Secretary of State's portal to identify your specific deadline month.
Yes, you can serve as your own registered agent for your Connecticut LLC if you maintain a Connecticut street address (not a PO Box) and are consistently available during business hours to receive legal documents and service of process. However, this requires significant personal commitment. You must respond to all documents within strict timeframes—missing a summons or lawsuit notice could result in a default judgment against your LLC. The Connecticut Secretary of the State's office (which processes all filings) requires your registered agent information on Form LLC-1, and any changes demand a formal amendment filing and associated fees. Most Connecticut LLC owners delegate this responsibility to professional registered agent services ($75–$150 annually) to ensure documents are never missed, maintain personal privacy by keeping home addresses off public records, and gain peace of mind knowing compliance deadlines won't slip through the cracks. If you choose self-representation, establish a reliable mail system and calendar alerts immediately.
Connecticut's total first-year cost for an LLC is $200, consisting of the $120 filing fee for the Certificate of Formation submitted to the Connecticut Secretary of the State and the $80 annual report fee due by June 1st of your first full calendar year of operation. This positions Connecticut $23 below the national average, making it a cost-competitive jurisdiction for LLC formation. The practical implication for owners is significant: you'll pay this $200 upfront investment without hidden state-level formation surcharges common in other states. However, note that this figure excludes optional costs like professional registered agent services (typically $75–$150 annually) or legal consultation fees. To move forward, prepare your Certificate of Formation with the required business information and file it directly through the Secretary of the State's online portal at portal.ct.gov, then set a calendar reminder for your annual report deadline.
