N.Y. Real Prop. Tax Law § 950
Upon the settlement of the account of taxes of a collecting officer in any city or town, the county treasurer shall, if requested, and if the collecting officer has fully paid over or duly accounted for all the taxes which he was by law to collect, give to such collecting officer or any of his sureties a written certificate of such settlement, duly acknowledged. Upon the filing thereof in the office of the clerk where the undertaking is recorded, the clerk shall enter satisfaction of such undertaking. The filing of the satisfaction shall discharge the lien of the undertaking upon the real property of the collecting officer and his sureties, but in no way shall impair the liability of the collecting officer and his sureties upon the undertaking for a failure on the part of the collecting officer to pay over moneys collected by him.
