Wisconsin Statutes Taxation (Ch. 70 to 79) § 77.08. Supplemental severance tax

At any time within one year after any cutting should have been reported, the department of natural resources after due notice to the owner and opportunity to be heard, and on evidence duly made a matter of record, may determine whether the quantity of wood products cut from any such land, did in fact substantially exceed the amount on which the severance tax theretofore levied was based, and if so shall assess a supplemental severance tax which, in all respects, shall have the same force and effect as the former severance tax, except only it shall not be a lien on any property the title of which has passed to a purchaser for value without notice.
