Rule 22.
Example 1: ABC is a retailer that sells widgets for a sales price of $10.00 each. ABC offers a quantity discount of $2.00 per widget if the customer purchases 10 widgets. Customer purchases 10 widgets at a sales price of $80.00. The taxable sales price of the widgets is $80.00.
Example 2: ABC is a retailer that sells musical instruments. ABC sells a baby grand piano to a customer for a sales price of $25,000.00. ABC's contract with the customer provides that if the customer pays $20,000.00 within 60 days, ABC must reduce the price of the piano to $20,000.00. The customer pays in 59 days. The taxable sales price of the property is $20,000.00. However, when the sale is first reported by ABC it must include gross proceeds of $25,000.00 on its return and remit the appropriate tax. If ABC collected tax from the customer on the $5,000.00 discount, ABC shall refund its customer before taking a credit or seeking a refund.
Example 3: ABC is a retailer that sells widgets manufactured by XYZ for a sales price of $10.00. XYZ mails manufacturer coupons to the public for $2.00 off per widget. ABC and XYZ have an agreement that XYZ will reimburse ABC $2.00 per widget sold when the coupon is presented. The agreement requires ABC to pass this discount on to its customers. A customer presents XYZ's coupon to ABC and ABC sells the customer a widget for $8.00. The taxable sales price of the widget for purposes of the seller's liability is $10.00. Even though the retailer only charged the purchaser a sales price of $8.00, the seller may collect the full 60 cents from the purchaser to reimburse itself for the sales tax due on the transaction in accordance with section 23(1) of the General Sales Tax Act, 1933 PA 167, MCL 205.73.
Example 4: XYZ, a non-profit member association and service organization, has agreements with various merchants and service providers under which XYZ's members are entitled to discounts. Membership in XYZ is based on a fee and is not available to the public free of charge. ACME Hotel Group is a merchant that provides its accommodations throughout this state to XYZ members at a discount under such an agreement. Depending on the location within this state, XYZ reimburses ACME Hotel Group in an amount equal to or less than the amount of the discount. At one of ACME Hotel Group's locations, a $100.00 hotel room is rented at a 10% discount to a XYZ member who pays $90.00 with the remaining $10.00 paid to ACME Hotel Group by XYZ. At another ACME Hotel Group location, a $100.00 hotel room is rented at a 10% discount to a XYZ member who pays $90.00 with only $6.00 of the remaining $10.00 paid by XYZ to ACME Hotel Group. ACME Hotel Group absorbs the remaining $4.00 to have the hotel room rented out. Use tax is due on the full consideration paid to ACME Hotel Group by the XYZ member and XYZ. In the first transaction, use tax of $6.00 is due on the consideration received by ACME Hotel Group of the $100.00 purchase price, while in the second transaction, use tax of $5.76 is due on the consideration of $96.00 received by ACME Hotel Group.
