N.Y. Comp. Codes R. & Regs. tit. 20, § 79.2
(b) Every dealer of cigarettes, including agents licensed to purchase and affix stamps, shall take a physical inventory of all cigarettes possessed in this State as of the close of business on June 30, 2010. In addition, every dealer who is a licensed agent shall take a physical inventory of all unaffixed cigarette tax stamps possessed as of the close of business on such date. Because it may be impossible to take a physical inventory of cigarettes in all vending machines that are on location throughout the State, a dealer may take as many physical inventories of the contents of such machines as is possible with available personnel. For those machines that cannot be physically inventoried as of the close of business on June 30, 2010, cigarettes may be accounted for at one-half of the normal fill capacities of such machines, as reflected in the individual inventory records maintained for such machines.
(c) Returns and payments.
