Illinois Additional Proof of Delivery (POD) is a document that provides evidence of delivery of goods to a customer in Illinois. It is an official record of the transfer of goods from a seller to a customer that is required to be retained by the seller for a period of three years. There are two types of Illinois POD: POD 1 and POD 2. POD 1 is used by legal entities that are registered in Illinois and are required by law to collect and remit sales tax. It is a document that must be signed by the customer and includes information such as the invoice number, the name and address of the customer, the date of delivery, the description of the goods, and the sales tax amount. POD 2 is used by non-registered entities and is a document that must be signed by the customer and includes information such as the invoice number, the name and address of the customer, the date of delivery, the description of the goods, the quantity delivered, and the sales tax amount. Both types of POD are used to provide evidence of delivery and serve as official records of the transfer of goods from a seller to a customer. They are critical documents for businesses in Illinois that are required to collect and remit sales tax.
