Wis. Admin. Code § Tax 11.26
(1) General rule.
(2) Taxes, fees, and charges included as part of sales price and purchase price. The following taxes, fees, and charges are included in the sales price and the purchase price, regardless of whether they are separately stated on the invoice, bill of sale, or other similar document given by the seller to the purchaser, except as provided in sub. (3):
(d) A federal, county, or municipal fuel tax included in the price of alternate fuels and general aviation fuel subject to sales tax.
Example: Fuel taxes are included in the price of fuel used in aircraft, boats, and for other nonhighway use. The taxes are included in the sales price.
(3) Taxes, fees, and charges excluded from sales price or purchase price. Section 77.51 (12m) (b) 3. and (15b) (b) 3., Stats., exclude from the sales price and purchase price any taxes legally imposed directly on the purchaser that are separately stated on the invoice, bill of sale, or similar document that the seller gives to the purchaser. Section 77.51 (12m) (b) 3m. and (15b) (b) 3m., Stats., exclude from the sales price and purchase price taxes imposed on the seller that are separately stated on the invoice, bill of sale, or similar document that the seller gives to the purchaser if the law imposing or authorizing the tax provides that the seller may, but is not required to, pass on to and collect the tax from the user or consumer. Therefore, the following taxes, fees, and charges are excluded from the sales price or the purchase price if they are separately stated on the invoice, bill of sale, or similar document given to the purchaser:
(j) The federal excise tax imposed on the first retail sale of heavy trucks and trailers under section 4051 of the Internal Revenue Code.
Note: Section Tax 11.26 interprets s. 77.51 (12m) and (15b) and 77.54 (37), Stats.
Note: The interpretations in s. Tax 11.26 are effective under the general sales and use tax law on and after September 1, 1969, except: (a) The exclusion for federal and Wisconsin motor vehicle excise taxes refunded became effective December 1, 1997, pursuant to 1997 Wis.
