In a vehicle sale, which fee paid to the seller or dealer is considered taxable?

• A. Document preparation fee
• B. SMOG fee paid to the seller/dealer
• C. Registration fee
• D. License plate fee

Answer: (B)

When a vehicle is sold, sales tax in Wisconsin is applied to the amount the buyer pays to the seller as part of the purchase, including fees charged by the seller that are tied to completing the sale. The SMOG (emissions) fee paid to the dealer is such a charge—it's collected by the seller in conjunction with the vehicle sale and thus becomes part of the tax base. Other items like a document preparation fee are dealer charges that aren’t treated the same way in this context, and fees paid to the DMV for registration or for license plates are government fees—not charges the seller collects as part of the sale—so they aren’t taxed by the dealer in the same manner. So the SMOG fee is the taxable one in this scenario.
