N.Y. Tax Law § 273
In every case where an adhesive stamp shall be used to denote the payment of the tax provided by this article, the person using or affixing the same shall write or stamp thereupon the initials of his name and the date upon which the same shall be attached or used, and shall cut or perforate the stamp in a substantial manner, so that such stamp cannot be again used; and if any person makes use of an adhesive stamp to denote the payment of the tax imposed by this article, without so effectually canceling the same, such person shall be deemed guilty of a misdemeanor, and upon conviction thereof shall pay a fine of not less than two hundred nor more than five hundred dollars or be imprisoned for not less than six months, or both, in the discretion of the court.
