How to File a CT LLC Annual Report: Deadline, Fee, and Reinstatement

Every Connecticut LLC must file a CT LLC annual report with the Secretary of the State between January 1 and March 31 each year and pay an $80 fee.¹ Filing happens online through the Business.CT.Gov portal and usually takes under fifteen minutes once your information is in front of you. Miss the deadline and your LLC risks losing good standing and, eventually, being dissolved by the state.

When the Report Is Due

Connecticut law requires every domestic LLC, and every foreign LLC registered to do business in the state, to file after January 1 and before April 1 each calendar year.¹ March 31 is the last day to file on time. The state’s forms-and-fees page lists the window the same way.²

If your LLC was formed partway through the year, your first report isn’t due until the following calendar year. An LLC formed in August 2025 files its first report between January 1 and March 31, 2026.¹ Foreign LLCs follow the same rule: the clock starts the calendar year after you register in Connecticut.

What to Have Ready Before You Log In

The portal won’t let you save a half-finished report, so gather everything first:

Your LLC’s legal name, exactly as it appears on the original articles of organization.
Your business street address and mailing address, each with street, city, state, and zip.
Your six-digit NAICS code identifying your industry.
The name and address of at least one member (if member-managed) or one manager (if manager-managed).
The name and Connecticut address of your current registered agent.

Connecticut’s filing page confirms the required fields: business email and street address, owner’s addresses, registered agent details, principal’s name and title, and NAICS code.³

You Can’t Change Your Registered Agent Through This Form

The annual report displays your current registered agent, but you can’t update it here. A new agent has to formally accept the appointment, which the report doesn’t accommodate, so you file a separate agent-change form on the same portal under “Agent Change.”⁴

How to File and Pay

All annual reports must be filed electronically through Business.CT.Gov.⁵ The steps:

Create a Business.CT.Gov account or sign in with your existing credentials.
Select “Manage your business” and locate your LLC by name or business ID number.
Review the pre-filled information and update anything that has changed, such as a new business address or a different manager.
On the summary screen, check the spelling of names and the accuracy of addresses.
Pay the $80 fee. The portal accepts Visa, Mastercard, Discover, and American Express; paper checks aren’t accepted online.⁶
Submit. The portal shows a confirmation screen and emails a receipt to the address on file.

The $80 fee is set by statute and applies to every LLC regardless of size or revenue.⁷ Keep the confirmation with your LLC’s records. If a filing date is ever disputed, that receipt is your proof.

What Happens If You Miss March 31

Connecticut doesn’t charge a late fee, but the consequences reach further than money. The immediate hit is that you can no longer obtain a Certificate of Legal Existence, which banks, lenders, landlords, and potential business partners often require.⁸ Routine transactions can stall without it.

Once your report is more than a year overdue, the Secretary of the State may email the address on file warning that your LLC’s rights and powers are considered forfeited. You then have three months from that notice to file. If you don’t, the Secretary files a certificate of dissolution by forfeiture, which terminates your LLC’s legal existence. A copy of the dissolution certificate goes to the LLC’s email on record, and notice is posted on the Secretary of the State’s website for sixty days.⁹

A dissolved LLC can’t enter into contracts, sue in court, or conduct business under its name. Personal liability protection may also be compromised during the period of dissolution.

Reinstating a Dissolved LLC

If your LLC has been dissolved for failure to file, you can reinstate it and keep the original formation date through the same Business.CT.Gov portal.¹⁰ To file online, your registered agent must be a Connecticut resident, and you’ll need your correct NAICS code and business email.

Reinstatement means filing every missing annual report and paying the $80 fee for each one. Three years behind means $240 in back report fees before any reinstatement filing costs. Once reinstated, your LLC receives an annual report due date for the year after reinstatement.¹⁰

The Annual Report Is Not a Tax Filing

Filing the annual report does not satisfy any tax obligation with the Connecticut Department of Revenue Services. Connecticut doesn’t impose a franchise tax on LLCs, but multi-member LLCs treated as partnerships federally may need to file Form CT-1065/CT-1120SI, and the state’s optional pass-through entity tax, once elected, is irrevocable and requires annual filing of Form CT-PET.¹¹ If you have employees, state withholding and unemployment insurance filings run separately through the Department of Labor. Track the March 31 report deadline and your tax deadlines on the same calendar; one doesn’t excuse the other.
