Net New Construction

​The Wisconsin Department of Revenue's Equalization Bureau issues the Net New Construction Report. This report provides municipalities and counties with net new construction numbers for levy limits and the Expenditure Restraint Program (ERP).


Report includes

  • Amount of net new construction - this amount is new construction reduced by any demolition or destruction of buildings, and may include corrections to the prior year
  • Levy limit percent - is a percentage calculated by dividing the current year net new construction by the prior year Equalized Value of a municipality or county

Net New Construction Report vs. Statement of Changes in Equalized Value Report

  • Net New Construction Report - reports net construction numbers that include new construction reduced by any demolition or destruction of buildings, and may include corrections to the prior year
  • Statement of Changes in Equalized Values Report - the new construction column reports the total new construction and higher land utility for each class. The column does not include removal of buildings (demolition) or corrections to the prior year.
