2023 Connecticut General Statutes › Title 33 - Corporations › Chapter 601 - Business Corporations › Section 33-921. - Consequences of transacting business without authority.

(a) A foreign corporation transacting business in this state without a certificate of authority may not maintain a proceeding in any court in this state until it obtains a certificate of authority.
(b) The successor to a foreign corporation that transacted business in this state without a certificate of authority and the assignee of a cause of action arising out of that business may not maintain a proceeding based on that cause of action in any court in this state until the foreign corporation or its successor obtains a certificate of authority.
(c) A court may stay a proceeding commenced by a foreign corporation, its successor, or assignee until it determines whether the foreign corporation or its successor requires a certificate of authority. If it so determines, the court may further stay the proceeding until the foreign corporation or its successor obtains the certificate.
(d) A foreign corporation is liable to this state, for the years or parts thereof during which it transacted business in this state without a certificate of authority, in an amount equal to (1) all fees and taxes which would have been imposed by law upon such corporation had it duly applied for and received such certificate of authority to transact business in this state, and (2) all interest and penalties imposed by law for failure to pay such fees and taxes. A foreign corporation is further liable to this state, for each month or part thereof during which it transacted business without a certificate of authority, in an amount equal to three hundred dollars, except that a foreign corporation which has obtained a certificate of authority not later than ninety days after it has commenced transacting business in this state shall not be liable for such monthly penalty. Such fees and penalties may be levied by the Secretary of the State. The Attorney General shall bring such action as he may deem necessary to recover any amounts due the state under the provisions of this subsection including an action to restrain a foreign corporation against which fees and penalties have been imposed pursuant to this subsection from transacting business in this state until such time as such fees and penalties have been paid.
(e) Notwithstanding subsections (a) and (b) of this section, the failure of a foreign corporation to obtain a certificate of authority does not impair the validity of its corporate acts or prevent it from defending any proceeding in this state.

History: P.A. 94-186 effective January 1, 1997; P.A. 97-228 deleted Subsec. (d)(3) re penalty of $2,000 for each year or part thereof during which a foreign corporation transacts business without a certificate of authority, replacing said annual penalty with a penalty of $165 for each month or part thereof that a foreign corporation transacts business without a certificate of authority and rephrasing provision re grace period, effective July 1, 1997; P.A. 98-137 amended Subsec. (d) to revise grace period by providing that a corporation is not liable for the monthly penalty if it has obtained a certificate of authority “not later than ninety days after it has commenced transacting” business in this state rather than not being liable “for the first three months or part thereof during which it transacted business without such certificate”, effective July 1, 1998; P.A. 98-219 revised effective date of P.A. 98-137, but without affecting this section; P.A. 09-83 amended Subsec. (d) to increase penalty from $165 to $300 for each month or part thereof that a foreign corporation transacts business without a certificate of authority and to make a technical change.
Foreign corporation that sought to recover credit card debt from consumer and that did not have a physical presence or employees in this state was “transacting business in interstate commerce” under Sec. 33-920(b)(11), and was not prohibited from maintaining action for failure to obtain a certificate of authority. 128 CA 843.
