Wis. Stat. § 78.51 — Theft of alternate fuels tax moneys

All sums paid by a purchaser of an alternate fuel to an alternate fuels dealer as alternate fuels taxes which have not been paid to the state are public moneys, the property of the state of Wisconsin. Any alternate fuels dealer who fails or refuses to pay over to the state the tax on an alternate fuel at the time required in this chapter, or who fraudulently withholds or appropriates or otherwise uses such moneys or any portion thereof belonging to the state is guilty of theft and shall be punished as provided by law for the crime of theft, irrespective of whether that alternate fuels dealer has or claims to have any interest in such moneys so received by that dealer.
