Except as otherwise provided in section 39-27-102 for persons that export gasoline, every person not a licensed distributor who uses any gasoline in this state or who has in his or her possession any gasoline, other than that contained in the ordinary fuel tank attached to a motor vehicle or aircraft, upon which a licensed distributor has not paid or is not liable for the tax imposed in this part 1 shall file a sworn statement with the executive director of the department of revenue on or before the twenty-sixth day of the calendar month on such form as the executive director prescribes and furnishes, showing the amount of gasoline so used and held, and shall pay to the executive director the tax imposed on all such gasoline. This section does not apply to a user who is exempt from taxation under section 39-27-102.5(9).
