Connecticut Corporate Certificates: Filing, Fees, and Good Standing

Connecticut corporate certificates are the documents a business files with the Secretary of the State to create, change, or close its legal existence in the state. The right certificate depends on your entity type and what you’re trying to do, and fees run from $120 for a domestic LLC to $385 for a foreign stock corporation. Miss a required filing and you can lose access to Connecticut courts, rack up monthly penalties, or have your entity administratively dissolved.

Which Certificate You File

Every filing starts with matching your situation to the correct document. There are four common ones.

Forming a Domestic Corporation

A domestic corporation comes into legal existence by filing a Certificate of Incorporation with the Secretary of the State under Connecticut General Statutes Section 33-636.1FindLaw. Connecticut General Statutes Title 33 Corporations – 33-636 The certificate carries the corporate name, authorized shares, initial registered office and agent, each incorporator’s name and address, a valid email, and the corporation’s NAICS code. The name must be distinguishable from names already on file, so a quick records search before you submit avoids a rejection.

Forming a Domestic LLC

LLCs file a Certificate of Organization under Section 34-247 instead.2Justia. Connecticut Code 34-247 – Formation of Limited Liability Company Certificate of Organization It does the same job as a Certificate of Incorporation but is tailored to the LLC structure, requiring the company name, principal office address, and registered agent.

Registering a Foreign Entity

A business formed in another state needs permission before transacting business in Connecticut. Foreign corporations obtain a Certificate of Authority under Section 33-920.3Justia. Connecticut Code 33-920 – Authority to Transact Business Required Foreign LLCs file a Foreign Registration Statement under Section 34-275b, listing the company name, home jurisdiction, principal office, a Connecticut registered agent, and at least one manager or member.4Connecticut General Assembly. Connecticut Code Chapter 613a – Uniform Limited Liability Company Act Both filings generally require proof of good standing from the home state.

Changing or Closing an Entity

When something in your articles changes — name, share structure, registered agent — file a Certificate of Amendment.5Business.CT.gov.

What Each Filing Costs

Fees are set by entity type and document, and all are non-refundable.

The Secretary of the State accepts electronic payments for online filings and checks or money orders for paper submissions. Foreign entity filings usually need additional paperwork, such as a certified copy of the formation documents from the home state.

How and Where to File

Filings go through the online portal at Business.CT.gov, by mail, or in person. The portal is the fastest route by a wide margin. Most online submissions are accepted automatically with immediate confirmation, and you can pay fees and track status in the same place. If you need faster turnaround, expedited service runs $50 per transaction and completes within 24 hours, but it’s only available on online filings — a mailed submission cannot be expedited.13Business.CT.gov. Expedited Services

Mail filings require the paper form and a check or money order, and processing takes longer because of mailing time and manual entry. Incomplete forms get returned, which adds more delay. In-person submissions give you a direct handoff at the Secretary of the State’s office, but the online portal already provides instant confirmation, so the practical gain is small.

Reserving a Name First

If you’re not ready to file formation documents, you can lock in your business name for 120 days by submitting an Application for Reservation of Name with a $60 fee.12Connecticut Secretary of the State. Application for Reservation of Name The clock starts on the filing date. Reservations are useful when you’re still gathering paperwork or waiting on financing. Run a name search in the Secretary of the State’s records before reserving, because the name still has to meet Connecticut’s distinguishability requirements.

Fixing Mistakes After Filing

If a certificate goes in with an error, you don’t have to start over. A Certificate of Correction fixes inaccuracies in a previously filed document. The filing identifies the original submission, states what was wrong, and gives the corrected information. Once accepted, the correction relates back to the original filing date. The fee is $20 for nonstock corporations under the statutory schedule, and fees for other entity types vary.14Justia. Connecticut Code 33-1013 – Fees Payable to Secretary of the State

A correction is not an amendment. Corrections fix clerical mistakes: a misspelled name, a wrong address, a transposed number. Amendments reflect a deliberate business decision, like a new name or a change in authorized shares. If the fix is substantive rather than clerical, you may need shareholder or member approval and should file an amendment.

Keeping the Entity in Good Standing

Formation is not a one-time filing. Connecticut requires annual reports from stock and nonstock corporations, LLCs, limited partnerships, and limited liability partnerships.15Business.CT.gov. File Annual Report For LLCs and foreign LLCs, the report is filed electronically between January 1 and April 1, with the first report due the year after formation or registration. It must list the company name, principal office, at least one manager or member with address, and the registered agent.4Connecticut General Assembly. Connecticut Code Chapter 613a – Uniform Limited Liability Company Act Corporations follow a similar annual cycle. Reports missing required information are returned for correction.

What Happens If You Don’t File

Noncompliance penalties scale fast, and they differ depending on what you skipped.

Foreign Entities Operating Without Authority

A foreign corporation that transacts business in Connecticut without a Certificate of Authority cannot sue in any Connecticut court until it registers. On top of that, it owes every fee and tax it would have paid, plus a $300 penalty for each month or partial month it operated unregistered. If the corporation obtains its certificate within 90 days of starting business in the state, the monthly penalty does not apply.16Justia. Connecticut Code 33-921 – Consequences of Transacting Business Without Authority

Administrative Dissolution

A domestic corporation more than one year behind on annual reports, or without a registered agent, can be administratively dissolved.17Justia. Connecticut Code 33-890 – Grounds for Administrative Dissolution The Secretary of the State sends an electronic notice to the corporation’s last email on file, and the company has three months to cure the problem. If it doesn’t, the Secretary files a certificate of administrative dissolution. A dissolved entity cannot enter contracts, conduct transactions, or defend itself in court. The same risk applies to LLCs that fail to file annual reports.

Reinstatement is available. The business keeps its original formation date, but it must submit a reinstatement application, bring all overdue reports current, and pay what it owes.18Business.CT.gov. Reinstating a Business A business that keeps operating after dissolution without reinstating exposes its members or officers to personal liability for obligations taken on during that period.
