Municipal Tax Incremental Finance (TIF) (Sec. 66.1105, Wis. Stats.) Territory Subtraction Amendment (subtracting parcels)

A municipality may amend boundaries of an active Tax Incremental District (TID) up to four times, by subtracting whole parcels currently within the TID boundaries.

To amend an active TID, email the completed territory amendment forms and required documents to the Wisconsin Department of Revenue (DOR).

Note on subtraction forms

  • List the subtracted parcels' values at the time they were added to the TID. If parcels were added in multiple years, submit separate Territory Subtraction Workbooks (in Excel format).
  • If numerous parcels are subtracted, it may be easier to list the remaining parcels instead of the subtracted ones. Contact DOR to discuss whether it is best to list the subtracted parcels or the remaining parcels

Due date/process

  • If the municipal resolution is adopted by September 30, use the "Attach Documents" button below to email the required forms and supporting documents to DOR by October 31
  • The municipality amends a TID by subtracting the parcels' original values from the base value
  • DOR certifies the amended base value after January 1 of the year following the amendment
  • TIF Fee – your municipality notifies DOR that it amended a TID, DOR posts a bill in My Tax Account
