VERIFICATION
    I declare that I have examined this return and, to the best of my knowledge, it is true, correct, and complete. I understand that the penalty for willfully filing a false return shall be a fine not to exceed $1,000 or imprisonment in a penal institution other than the penitentiary not to exceed one year, or both a fine and imprisonment.
          ...............      ......................
          Date                 Signature of purchaser,
                               transferee, or donee
    The return and payment from the purchaser, transferee, or donee shall be submitted to the Department within 30 days after the date of purchase, donation, or other transfer or the date the aircraft is brought into the State, whichever is later. Payment of tax shall be a condition to securing registration of the aircraft from the Division of Aeronautics of the Department of Transportation.
    When a purchaser, transferee, or donee pays the tax imposed by Section 10-15 of this Law, the Department (upon request therefor from the purchaser, transferee, or donee) shall issue an appropriate receipt to the purchaser, transferee, or donee showing that he or she has paid such tax to the Department. The receipt shall be sufficient to relieve the purchaser, transferee, or donee from further liability for the tax to which the receipt may refer.
