No court order needed: if the entity has no registered agent, or the agent cannot with reasonable diligence be served, the corporation may be served by registered or certified mail, return receipt requested, addressed to the secretary of the corporation at its principal office (LLCs: addressed to the company at its principal office, or by similar commercial delivery service). Service is effective at the earliest of receipt, the signed return-receipt date, or five days after deposit in the mail.
Administrative Dissolution. LLC: parallel 'dissolution by forfeiture' - a delinquent LLC that has failed to maintain a registered agent gets electronic-mail notice; unless it files an appointment of a registered agent within three months, the Secretary files a certificate of dissolution by forfeiture. The dissolved LLC continues only to wind up or apply for reinstatement.
Reinstatement Fee. Reinstatement after administrative dissolution requires payment of all penalties and forfeitures plus a reinstatement fee ($150 corporate application for reinstatement, § 33-617(a)(15); $120 LLC certificate of reinstatement, § 34-243u(a)(11)), a current annual report, tax-clearance statements (corporations), and an appointment of a registered agent.

How the gate works.
Governance rules
7 governance rules are recorded for Connecticut - the organizational and annual meetings, action by written consent, and whether bylaws or an operating agreement are mandatory. Each verified rule links to the statutory text it was verified against, quoted verbatim below.
Organizational meeting required · applies to
corporations ·
yes
If initial directors are named in the certificate of incorporation, the initial directors shall hold an organizational meeting... to complete the organization of the corporation by appointing officers, adopting bylaws
Annual meeting required · applies to
corporations ·
yes
a corporation shall hold a meeting of shareholders annually at a time stated in or fixed in accordance with the bylaws... The failure to hold an annual meeting... does not affect the validity of any corporate action.
Operating agreement required · applies to
LLCs ·
no
"Operating agreement" means the agreement, whether or not referred to as an operating agreement and whether oral, implied, in a record or in any combination thereof, of all the members
Action by written consent allowed · applies to
LLCs ·
yes
Matters in the ordinary course of the activities of the company shall be decided by the affirmative vote or consent of a majority in interest of the members.
TOWN Clerk of the town where business is principally transacted (CGS §35-1, ch. 620). Connecticut has no county-level filing - footprint 'counties' normalized to towns: 'East Hartford County' = Town of East Hartford; 'Stamford County' = City of Stamford Town Clerk. No state-level DBA filing (SOTS only publishes forms/guidance).
5 years from issuance (law change effective Jan 1, 2025); certificates filed before Jan 1, 2025 expire Dec 31, 2029
Renewal
Same 6-month window for post-2025 certificates, BUT legacy (pre-1/1/2025) trade names may be renewed at ANY time before 12/31/2029, and the renewed certificate runs 5 years from the date the town clerk accepts the renewal (not from the 2029 expiration)
Connecticut prohibits transacting business under any assumed or fictitious name unless a trade name certificate has been issued by the town clerk of the town where the business is principally transacted. The chapter was rewritten by P.A. 24-111 effective January 1, 2025: former § 35-1 was repealed and replaced by §§ 35-1a to 35-1e, which add Secretary of the State prescribed forms, a statewide electronic search system, and a five-year certificate term.
Where it is filed
The application is filed, on a form prescribed by the Secretary of the State, with the town clerk of the town where the business is or will be principally transacted (Connecticut has no county-level filing). The Secretary of the State maintains an electronic system for town clerks to process applications, with statewide public searching.
Publication
Chapter 620 contains no newspaper-publication requirement; the process is application, acknowledgment before an authority qualified to administer oaths, and issuance of the certificate by the town clerk.
Term and renewal
A trade name certificate is valid for five years from the date of issuance. Certificates issued before January 1, 2025 expire December 31, 2029 unless renewed.
Name restrictions
Partnerships, common-law trusts, associations, and individuals using a trade name may not use 'bank,' 'banking,' 'banker,' 'bankers,' 'trust' or 'savings' in the name (with narrow exceptions). Separately, § 35-1e restricts using an assumed name containing a Connecticut municipality's name in printed advertising in a way that misleadingly suggests the business is located there.
Assumed names for registered entities
A foreign corporation whose real name is unavailable in Connecticut may obtain a certificate of authority under a fictitious name (containing a corporate indicator) adopted by certified board resolution filed with its application. A foreign LLC with a noncomplying name must adopt an alternate name to register, and after registering may also transact business under a chapter 620 assumed name.
Penalties
Transacting business in violation of §§ 35-1a to 35-1e is punishable by a fine of up to $500, imprisonment up to one year, or both. Failure to comply is also deemed an unfair or deceptive trade practice under the Connecticut Unfair Trade Practices Act (CUTPA).

Common questions
Where do I file a trade name (DBA) in Connecticut?
With the town clerk of the town where the business is or will be principally transacted, on a form prescribed by the Secretary of the State (Conn. Gen. Stat. § 35-1a(b)). The Secretary of the State also maintains an electronic system for town clerks that provides statewide public searching of trade name certificates (§ 35-1c(b)).
How long is a Connecticut trade name certificate valid?
Five years from the date of issuance. It can be renewed during the window starting six months before expiration and ending on the expiration date, for another five years. Certificates issued before January 1, 2025 expire December 31, 2029 unless renewed (Conn. Gen. Stat. §§ 35-1a(d)-(e), 35-1b(a)).
Does registering a Connecticut trade name give me exclusive rights to the name?
No. The statute states that nothing in the chapter requires a town clerk to determine that a certificated trade name is unique in the town of filing or any other town in the state (Conn. Gen. Stat. § 35-1d(c)).
What are the penalties for doing business in Connecticut without a required trade name certificate?
A fine of up to $500, imprisonment of up to one year, or both, and the failure to comply is also deemed an unfair or deceptive trade practice under CUTPA (Conn. Gen. Stat. § 35-1d(d)).

○Pending review
What it is called
Corporation Business Tax
Administering agency
Connecticut Department of Revenue Services (DRS)
Basis of the tax
income-based (greater of 7.5% of net income or capital base/net worth mill tax, capital base phasing out through income year 2027), with $250 flat minimum
Minimum
$250
Due date
15th day of the month following the due date of the corresponding federal return (May 15 for calendar-year C corps); extension to the 15th day of the 11th month
Corporations
true - every corporation (or association taxable as a corporation) carrying on business or having the right to carry on business in CT files Form CT-1120 (combined unitary groups file CT-1120CU); S corporations are generally not subject to the CBT (pass-through regime)
LLCs
false unless taxed as a corporation - LLCs classified as corporations for federal tax pay the CBT; default (partnership/disregarded) LLCs pay no entity-existence tax since the $250 biennial Business Entity Tax ended for any tax period beginning after 12/31/2018 (P.A. 19-117)
The tax does not reach LLCs - a positive finding in the record.
