Updated September 4, 2026. Quick answer: a dissolved Connecticut corporation reinstates by filing Certificate of Reinstatement (Corporation – Stock & Nonstock), filed with the Connecticut Secretary of the State, Business Services Division under Conn. Gen. Stat. § 33-892 (reinstatement following administrative dissolution); see also § 33-891 (effect of administrative dissolution) and § 33-893 (appeal from refusal of reinstatement) – Title 33, Chapter 601, the Connecticut Business Corporation Act for $300, with no statutory deadline to do it.
If you’d rather have the reinstatement filed for you
Bizee can prepare and file the Connecticut reinstatement paperwork described above on your behalf. State filing fees and any back taxes owed are separate, and you pay those directly either way.
Bizee’s BBB rating, verified directly against BBB’s own listing on September 2, 2026: a C, not accredited. BBB’s own finding: the business “has failed to resolve underlying cause(s) of a pattern of complaints,” with 83 complaints filed. Most complaints we found described difficulty canceling recurring services and strict refund policies, worth knowing before you hand over a card for the year-two renewal. Check BBB’s current listing yourself before you buy; a rating we didn’t just verify is worse than none.

The filing, and what Connecticut calls it
Connecticut calls this process ‘reinstatement.’ It is triggered when the Secretary of the State has administratively dissolved a business corporation (most commonly for a defaulted annual report) under the Connecticut Business Corporation Act. Under § 33-892(a), a dissolved corporation may apply to the Secretary of the State for reinstatement at any point after the effective date of dissolution. Once the Secretary approves the application and files a Certificate of Reinstatement, the reinstatement relates back to the effective date of the dissolution and the corporation is treated as if the dissolution had never occurred.
How long you have to reinstate
Connecticut sets no deadline for reinstating a dissolved corporation. Conn. Gen. Stat. § 33-892(a) allows a dissolved corporation to apply for reinstatement ‘after the effective date of dissolution’ with no stated outer time limit. The statute’s own official history note confirms this was a deliberate change: Public Act 96-271 amended § 33-892(a) to ‘delete the three-year time limitation on reinstatement after dissolution,’ effective January 1, 1997. Connecticut previously imposed a 3-year reinstatement window but eliminated it decades ago. That does not mean waiting is free; back fees and penalties keep accruing the whole time the entity sits dissolved. (Conn. Gen. Stat. § 33-892(a); History note to § 33-892 citing P.A. 96-271, S. 121, 254)
What you must pay before it goes through
Connecticut will not reinstate the corporation until every year it sat delinquent is paid for. Before the Secretary of the State will issue a Certificate of Reinstatement, the application must be accompanied by: (1) payment of all penalties and forfeitures the corporation has incurred, plus a reinstatement fee; (2) an annual report for the current year; (3) up-to-date statements from the Commissioner of Revenue Services and the unemployment compensation administrator confirming taxes/contributions are paid, not owed, or adequately secured; and (4) appointment of a registered agent. The official reinstatement form lists a combined filing fee of $300 (stock) or $160 (nonstock), stated to ‘include annual report fee’ – separate penalty/forfeiture/back-tax amounts are billed outside that flat fee. (Conn. Gen. Stat. § 33-892(a)(3)(A)-(D); CT Secretary of the State, Certificate of Reinstatement form, rev. 05/01/2020)
Whether your name is still yours
Your original name is not guaranteed to still be yours. Yes – the statute directly contemplates that another entity may take the corporation’s name while it is administratively dissolved. If, at the time of reinstatement, ‘the name of the corporation to be reinstated is no longer available,’ the application must be accompanied simultaneously by an amendment to the certificate of incorporation adopting a new, available name. Check Connecticut’s business-name database before assuming the reinstatement filing will go through under the old name. (Conn. Gen. Stat. § 33-892(a)(2))
What the filing costs
Connecticut’s Certificate of Reinstatement (Corporation – Stock & Nonstock), filed with the Connecticut Secretary of the State, Business Services Division carries a $300 filing fee. Per the Secretary of the State’s official Certificate of Reinstatement form (rev. 5/1/2020): $300 for a stock (for-profit) business corporation, $160 for a nonstock corporation; stated to ‘include annual report fee.’ Does NOT include any separate penalties, forfeitures, or delinquent-tax amounts required under § 33-892(a)(3)(A).
What this page does not answer
Reinstating the entity at the state level and squaring things up with the IRS are two separate processes. Late federal returns, penalty abatement requests, and reinstating a lapsed EIN’s associated accounts are governed by federal law, not by Connecticut’s corporation statute, and this page does not source them. We have the state-filing answer at primary and the federal-cleanup answer not at all.
This page covers a for-profit business corporation. If you are reinstating an LLC in Connecticut instead, the filing, fee and statute are different: see reinstating an LLC in Connecticut.
