a) Every cultivator shall keep books and records of all sales of cannabis, together with invoices, bills of lading, sales records, copies of bills of sale, monthly inventories, inventories prepared as of December 31 of each year, and other pertinent papers and documents. [35 ILCS 120/7]
b) All books and records and other papers and documents that are required by this Section and the Law to be kept shall be kept in the English language and shall, at all times during business hours of the day, be subject to inspection by the Department or its duly authorized agents and employees. [35 ILCS 120/7] Records shall be maintained at the physical location of the cultivator. All books and records kept by a cultivator pursuant to rules adopted by the Department of Agriculture to implement the Act shall, at all times during business hours of the day, be subject to inspection by the Department or its duly authorized agents and employees. The Department shall also have access to the cultivator's automated data processing and/or point of sale system.
c) Books and records and other papers reflecting gross receipts received during any period with respect to which the Department is authorized to issue notices of Tax liability shall, for purposes of this Part, be preserved until the expiration of that period unless the Department, in writing, authorizes their destruction or disposal prior to that expiration. The Department will not issue a notice of Tax liability on and after each July 1 and January 1 covering gross receipts received during any month or period of time more than 3 years prior to that July 1 and January 1, respectively. [35 ILCS 120/7] However, if the Department allows a cultivator to destroy books and records prior to the expiration of the preservation period, the cultivator is not relieved of any obligation to maintain books and records under any rule or regulation adopted by another State agency to implement the Act.
