78.57(4)(4) Issue. If the application and the bond under sub. (9), if that bond is required, are approved, the department shall issue a license in as many copies as the licensee has places of business for which a general aviation fuel license is required.

78.57(9)(a)(a) To protect the revenues of this state, the department may require any person liable to the department for the tax imposed by this subchapter to place with it, either before or after a general aviation fuel license is issued, security in an amount which the department determines. The amount of security required may be increased or decreased as the department deems necessary, but may not exceed 3 times the licensee’s average monthly liability for taxes under this subchapter, as estimated by the department. If an applicant or licensee fails or refuses to place such security, the department may refuse to issue or may revoke the license. If any taxpayer is delinquent in the payment of taxes imposed by this subchapter, the department may, upon 10 days’ advance written notice, recover the taxes, interest, penalties, cost and disbursements from the taxpayer’s security placed with the department. No interest may be paid or allowed by the state to any person for the deposit of the security.

78.57(9)(b)(b) The security required by this subsection may be in the form of a surety bond furnished to the department payable to the state to secure payment of any and all general aviation fuel taxes, interest and penalties accrued under this subchapter, together with costs and disbursements incurred in the collection thereof. The department shall prescribe the form and contents of the bond.

78.57(9)(c)(c) Section 78.11 (2) to (4), regarding motor vehicle fuel licensees’ bonds, also applies to bonds furnished by general aviation fuel applicants and licensees under this subsection.

78.58(1)(a)(a) For the purpose of determining the amount of the licensee’s liability to the state for the tax imposed by this subchapter, except as provided in par. (b), each general aviation fuel licensee shall, not later than the 20th day of each month, file a monthly report for the next preceding month. The licensee or the licensee’s duly authorized agent shall sign the report.

78.58(1)(b)(b) The department may allow a licensee whose tax liability is less than or equal to $500 per quarter to file on a quarterly basis. The licensee shall file the quarterly report for the next preceding quarter on or before the 20th day of each quarter.

78.58(2)(2) Reports of others. Any person, not a general aviation fuel licensee, who places any general aviation fuel in the fuel supply tank of an aircraft in this state upon which the general aviation fuel tax has not been paid or the liability therefor has not been incurred by any general aviation fuel licensee in this state, shall file a report and make payment of the tax on the general aviation fuel and shall be subject to this chapter in the same manner as is provided for general aviation fuel licensees.

78.58(3)(3) Computation of tax. Each general aviation fuel licensee at the time of making the monthly or quarterly report shall compute and pay the full amount of the general aviation fuel tax for the next preceding month or quarter, which shall be computed as follows: the number of gallons of general aviation fuel placed into the fuel supply tanks of an aircraft or into bulk storage facilities by the general aviation fuel licensee, multiplied by 0.06 and the resulting figure expressed in dollars.

78.59(1)(1) Notice required. Whenever any general aviation fuel licensee ceases to perform any of the acts for which a general aviation fuel license is required, the licensee shall notify the department in writing. The notice shall give the date of cessation and, in the event of sale or transfer of the business, the name and address of the purchaser or transferee thereof.

78.59(2)(2) Final report. Every general aviation fuel licensee shall, upon such cessation, sale or transfer of the business or upon the cancellation or revocation of a license, make a report as required in s. 78.58 and pay all general aviation fuel taxes and penalties due the state.

78.6078.60 Theft of general aviation fuel tax moneys. All sums paid by a purchaser of general aviation fuel to any general aviation fuel dealer as general aviation fuel taxes, which have not theretofore been paid to the state, are public moneys, the property of this state. Any general aviation fuel dealer who fails or refuses to pay over to the state the tax on general aviation 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 such general aviation fuel dealer has or claims to have any interest in such moneys so received.

78.6178.61 Presumption. For the purpose of enforcing this chapter, it is prima facie presumed that all general aviation fuel received by a general aviation fuel dealer or a general aviation fuel user into storage and dispensing equipment designed to fuel aircraft is to be transferred or delivered by the dealer or user into the supply tanks of aircraft.
