77.54 Annotation Under ss. 77.51 (15b) (a) and 77.52 (1) (a), the sales tax applies to the “sales price”—that is, the total amount of consideration paid for a sale, lease, or service, with no deductions for the seller’s or lessor’s costs. The sale of aircraft parts and maintenance, however, is exempt from sales tax under sub. (5) (a) 3. and s. 77.52 (2) (a) 10. When a lessor or lessee buys aircraft repairs or engine maintenance directly, that transaction is tax-exempt. But when a lessor passes those costs along to its lessees as part of the total amount of consideration in a lease, that transaction is taxable. When a lessor leases its aircraft, it is not selling aircraft repairs or engine maintenance. It is leasing an aircraft. Thus, the total lease price is taxable. Citation Partners, LLC v. DOR, 2023 WI 16, 406 Wis. 2d 36, 985 N.W.2d 761, 20-1683.

77.55(2m) (2m) There is exempted from the computation of the amount of sales tax the sales price from sales of railroad crossties to a common or contract carrier, shipped wholly or in part by way of the purchasing carrier under a bill of lading, whether the freight is paid in advance or the shipment is made freight charges collect, to a point outside this state if the property is transported to the out-of-state destination for use by the carrier in the conduct of its business as a carrier. Interruption of the shipment for storage, drying, processing or creosoting of the railroad crossties in this state does not invalidate the exemption under this subsection.

77.585 77.585 Return adjustments.

77.585(1) (1) 

77.585(1)(a) (a) In this subsection, “bad debt” means the portion of the sales price or purchase price that the seller has previously reported as taxable under this subchapter, and for which the seller has paid the tax, and that the seller may claim as a deduction under section 166 of the Internal Revenue Code. “Bad debt” does not include financing charges or interest, sales or use taxes imposed on the sales price or purchase price, uncollectible amounts on tangible personal property or items, property, or goods under s. 77.52 (1) (b), (c), or (d) that remain in the seller’s possession until the full sales price or purchase price is paid, expenses incurred in attempting to collect any debt, debts sold or assigned to 3rd parties for collection, and repossessed property or items.

77.585(1)(b) (b) A seller may claim as a deduction on a return under s. 77.58 the amount of any bad debt that the seller writes off as uncollectible in the seller’s books and records and that is eligible to be deducted as a bad debt for federal income tax purposes, regardless of whether the seller is required to file a federal income tax return. A seller who claims a deduction under this paragraph shall claim the deduction on the return under s. 77.58 that is submitted for the period in which the seller writes off the amount of the deduction as uncollectible in the seller’s books and records and in which such amount is eligible to be deducted as bad debt for federal income tax purposes. If the seller subsequently collects in whole or in part any bad debt for which a deduction is claimed under this paragraph, the seller shall include the amount collected in the return filed for the period in which the amount is collected and shall pay the tax with the return.

77.585(1)(c) (c) For purposes of computing a bad debt deduction or reporting a payment received on a previously claimed bad debt, any payment made on a debt or on an account is applied first to the price of the tangible personal property, or items, property, or goods under s. 77.52 (1) (b), (c), or (d), or service sold, and the proportionate share of the sales tax on that property, or items, property, or goods under s. 77.52 (1) (b), (c), or (d), or service, and then to interest, service charges, and other charges related to the sale.

77.585(1)(d) (d) A seller may obtain a refund of the tax reported for any bad debt amount deducted under par. (b) that exceeds the amount of the seller’s taxable sales as provided under s. 77.59 (4), except that the period for making a claim as determined under s. 77.59 (4) begins on the date on which the return on which the bad debt could be claimed would have been required to be submitted to the department under s. 77.58.

77.585(1)(e) (e) If a seller is using a certified service provider, the certified service provider may claim a bad debt deduction under this subsection on the seller’s behalf if the seller has not claimed and will not claim the same deduction. A certified service provider who receives a bad debt deduction under this subsection shall credit that deduction to the seller and a certified service provider who receives a refund under this subsection shall submit that refund to the seller.

77.585(1)(f) (f) If a bad debt relates to the retail sales of tangible personal property, or items, property, or goods under s. 77.52 (1) (b), (c), or (d), or taxable services that were sourced to this state and to one or more other states, as determined under s. 77.522, the total amount of such bad debt shall be apportioned among the states to which the underlying sales were sourced in a manner prescribed by the department to arrive at the amount of the deduction under par. (b).

Effective date text 1. “Bad debt” means the portion of the sales price or purchase price that the seller has previously reported as taxable under this subchapter, and for which the seller has paid the tax, and that the seller or lender may claim as a deduction under section 166 of the Internal Revenue Code. “Bad debt” does not include financing charges or interest, sales or use taxes imposed on the sales price or purchase price, uncollectible amounts on tangible personal property or items, property, or goods under s. 77.52 (1) (b), (c), or (d) that remain in the seller’s possession until the full sales price or purchase price is paid, expenses incurred in attempting to collect any debt, debts sold or assigned to 3rd parties for collection, not including dual purpose credit debts and private label credit debts, and repossessed property or items.

Effective date text 2. “Dual purpose credit card” means a credit card that may be used as a private label credit card or to make purchases from persons other than the seller whose name or logo appears on the card or the seller’s affiliates or franchisees, if the credit card issuer is able to determine the sales receipts of the seller and the seller’s affiliates or franchisees apart from any sales receipts of unrelated persons.

Effective date text 3. “Dual purpose credit debt” means accounts and receivables that result from credit sale transactions using a dual purpose credit card, but only to the extent the account or receivable balance resulted from purchases made from the seller whose name or logo appears on the card.

Effective date text 4. a. “Lender” means any person who owns a private label credit debt, an interest in a private label credit debt, a dual purpose credit debt, or an interest in a dual purpose credit debt, if the person purchased the debt or interest directly from a seller who remitted the tax imposed under this subchapter or from a third party or if the person originated the debt or interest pursuant to the person’s contract with the seller who remitted the tax imposed under this subchapter or with a third party.

Effective date text b. “Lender” includes any person who is a member of the same affiliated group, as defined under section 1504 of the Internal Revenue Code, as a lender or is an assignee or other transferee of a lender.

Effective date text 5. “Private label credit card” means any charge card or credit card that identifies a seller’s name or logo on the card and that may be used only for purchases from that seller or from any of the seller’s affiliates or franchisees.

Effective date text 6. “Private label credit debt” means accounts and receivables that result from credit sale transactions using a private label credit card, but only to the extent the account or receivable balance resulted from purchases made from the seller whose name or logo appears on the card.

Effective date text (b) A seller may claim as a deduction on a return under s. 77.58 the amount of any bad debt that the seller or lender writes off as uncollectible in the seller’s or lender’s books and records and that is eligible to be deducted as a bad debt for federal income tax purposes, regardless of whether the seller or lender is required to file a federal income tax return. A seller who claims a deduction under this paragraph shall claim the deduction on the return under s. 77.58 that is submitted for the period in which the seller or lender writes off the amount of the deduction as uncollectible in the seller’s or lender’s books and records and in which such amount is eligible to be deducted as bad debt for federal income tax purposes. If the seller or lender subsequently collects in whole or in part any bad debt for which a deduction is claimed under this paragraph, the seller shall include the amount collected in the return filed for the period in which the amount is collected and shall pay the tax with the return.

Effective date text (bm) For purposes of par. (b), a seller may compute the seller’s bad debt deduction using an estimate, if the department approves the method for computing the estimate. The department may audit the seller’s books and records to review the estimate and adjust the estimate as necessary to reflect the actual allowable bad debt amount.

Effective date text (c) For purposes of computing a bad debt deduction or reporting a payment received on a previously claimed bad debt, any payment made on a debt or on an account is applied first to the price of the tangible personal property, or items, property, or goods under s. 77.52 (1) (b), (c), or (d), or service sold, and the proportionate share of the sales tax on that property, or items, property, or goods under s. 77.52 (1) (b), (c), or (d), or service, and then to interest, service charges, and other charges related to the sale. If payment is received on an account for which the balance reflects multiple sales transactions, the payment is applied to the sales transactions in the same order in which the sales transactions occurred.

Effective date text (d) A seller may obtain a refund of the tax reported for any bad debt amount deducted under par. (b) that exceeds the amount of the seller’s taxable sales as provided under s. 77.59 (4), except that the period for making a claim as determined under s. 77.59 (4) begins on the date on which the return on which the bad debt could be claimed would have been required to be submitted to the department under s. 77.58.
