New York Consolidated Laws, Real Property Tax Law - RPT § 1588. Posted tax roll

Notwithstanding any provision of law to the contrary, information regarding date of payment of taxes, the receipt number and related information need not be posted on the tax roll or other printed record of payment if that information is entered into the data file and retained by means of electronic data processing.  This information must be stored so that it can be made readily available to the public in legible form.  At the conclusion of the period for the redemption of property from taxes which become a lien on such roll, a copy of the posted tax roll shall be produced in either a paper format or archival quality microform and be permanently retained as a public record.
