Conn. Gen. Stat. § 33-217: Annual license fee.

Any such corporation shall pay, during January of each year, to the Secretary of the State, a license fee of fifty dollars. If such fee is not paid on or before February first, a penalty of fifty dollars shall be added thereto, and such fee, together with such penalty, shall thereafter bear interest at the rate of nine per cent per annum. The Attorney General shall have power to collect such fee, penalty and interest thereon in the same manner as provided in section 12-28; provided the Attorney General may, upon such terms as he may prescribe, remit, either in whole or in part, the amount of such fees, penalty and interest thereon, when, in his opinion, it would be inequitable to enforce collection thereof.
