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

A municipality may amend boundaries up to four times by subtracting whole parcels that are contiguous to the existing boundaries.

To amend an active Tax Incremental District (TID), the municipality must submit the completed territory amendment forms with supporting documents to the Wisconsin Department of Revenue (DOR).


  • List the values of the subtracted parcels 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 document the remaining parcels instead of the subtracted ones. Contact DOR to discuss which option is best.

Due date/process

  • If the municipal resolution is adopted by September 30, the application forms and supporting documents are due 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
  • Tax Incremental Financing Remittance Fee – after notifying DOR of the amended TID, we will issue a bill through "My Tax Account"
