Connecticut LLC Annual Report Due by March 31 Since the 2018 Change

Why a Connecticut LLC’s Formation Month Doesn’t Set Its Due Date

Until 2018, a Connecticut LLC filed in its anniversary month, by the last day, as Connecticut corporations still do. The rule now in section 34‑247k of the Connecticut General Statutes gives one window to every LLC, so older instructions that send an LLC to its anniversary month describe the pre-2018 rule or a corporation’s report.

“Subsequent annual reports must be filed with the Secretary of the State after January first and before April first of each calendar year thereafter.”

Connecticut General Statutes § 34‑247k(c)

The same subsection places the first report in the calendar year that follows formation, or after a foreign LLC’s Connecticut registration. The statute counts to “before April first” and calls the $80 a filing fee, so CGS § 1‑3a, which carries a license or permit fee due on a weekend to the next business day, may not reach it; the tool marks the Friday for 2029 and 2030.

The $80 Connecticut LLC Annual Report Fee, Once $20

The $80 annual report filing fee comes from § 34‑243u(a)(15). Since the report is filed online only, § 34‑247k(e) lets the Secretary of the State exempt, on request, an LLC unable to file or pay electronically.

$80

Annual report, every year§ 34‑243u(a)(15); a foreign LLC pays the same $80, a foreign corporation $435.

$25

Amended annual report, when details changeRequired since January 1, 2025 when a detail other than the name changes between two reports (§ 34‑247k(g)); a change in the 30 days before the due month goes in the next report.

$50

Change of registered agentThe change of agent certificate under § 34‑243u(a)(4); an amended annual report can also update the agent.

$0

Filing after March 31No late fee appears in the statute’s fee list.

Articles that still quote a $20 fee predate July 2020: § 34‑243u keeps $20 only for a report “concerning any year prior to July 1, 2020.” The Business Entity Tax, once collected by the Department of Revenue Services, “no longer exists” under Public Act 19‑117, and an LLC with a corporate tax election deals with the DRS corporation business tax separately while still filing this $80 report.

What Business.CT.gov Asks for in the Annual Report

The report has no mail-in form: Business.CT.gov states that all annual reports must be filed online, and the content requirements sit in § 34‑247k(a). Questions go to the Secretary of the State’s Business Services Division at bsd@ct.gov or through a support ticket.

1. Sign in to Business.CT.gov, or create an account with a name, username, email address, mobile number and password, confirmed by a code sent by email.
2. Choose “File annual report” and find the LLC by its name or its Business ID (on Secretary of the State notices).
3. Bring the details below up to date: they must be accurate as of the date of signing (§ 34‑247k(b)).
4. Pay $80 by Mastercard, Visa, Discover or American Express. An email follows saying whether the report was accepted; an incomplete one is returned for correction.

• Principal officeStreet address and mailing address.
• One member or managerName, business address and residence address (§ 34‑247k(a)); one is the legal minimum.
• Registered agentIts name and address, as on file.
• Email addressA valid one, required on every report.Required since January 1, 2025
• NAICS codeThe North American Industry Classification System code of the LLC’s activity.
• Foreign LLCs onlyHome jurisdiction, any alternate name, and the office address that jurisdiction requires.

The email field carries more weight than it looks. Since Public Act 24‑111 took effect on January 1, 2025, §§ 34‑267g and 34‑275g have the Secretary of the State send a dissolution or revocation notice, and the certificate that follows it, to the email on record instead of by mail, so the warning reaches only the email address last on the Secretary of the State’s records.

What Changes for a Late Connecticut LLC, and When It Is Forfeited

A late Connecticut annual report still costs $80, with no surcharge: asked about an additional or penalty fee, the Secretary of the State’s annual report FAQ answers “No.” What stops is the Certificate of Legal Existence, Connecticut’s good standing certificate, which isn’t issued while a report is missing.

1. March 31, 2026Last day to file the 2026 report.
2. April 1, 2026Overdue: no fee added, no Certificate of Legal Existence.
3. After April 1, 2027More than one year in default: under § 34‑267g, the Secretary of the State “may notify” the LLC by email, whenever the default comes to the office’s attention.
4. Three months after that emailUnless the report is filed, a certificate of dissolution by forfeiture, posted 60 days on the Secretary of the State’s site. The office’s notice page counts 90 days from the date printed on the notice.

A foreign LLC has no one-year cushion in the statute. § 34‑275g lists a missing annual report as a cause for revoking its registration after a notice of at least 20 days.

A Forfeited Connecticut LLC Can Be Reinstated at Any Time

Section 34‑267b allows reinstatement “at any time after its dissolution,” unless the Superior Court ordered the dissolution. The certificate of reinstatement costs $120, not $50, and goes in with the annual report for the current year, an appointment of a registered agent and the written consent of “a majority in interest of the members.”

Online filing

From “Manage your business,” then “Reinstatement”; the agent must be a Connecticut resident, and the NAICS code and business email must be correct.

Review time

One business day with expedited filing, usually 3 to 5 business days without it.

Name

If another business now holds the name, the LLC takes an available name as part of the reinstatement (§ 34‑267b(b)(4)).

Next report

Due in the January to March window of the year after reinstatement.

The Revocation Date a Returning Foreign LLC Must Use

A foreign LLC with a revoked registration files a new foreign registration rather than a reinstatement. As the date it began business in Connecticut, the Secretary of the State asks for the date the certificate of revocation was filed; another date can bring a foreign penalty letter.

When the LLC Has Stopped Doing Business

Not filing doesn’t close a Connecticut LLC. According to the Secretary of the State’s FAQ, an entity stays active, and keeps receiving annual report notices, until a dissolution or withdrawal is on file, and Business.CT.gov says no “final annual report” is needed.
