Tax Incremental Finance (TIF) Base Value Redetermination (sec. 66.1105, Wis. Stats.)

​​​A municipality may request a base value redetermination for a Tax Incremental District (TID) in a decrement situation, under state law (sec. 66.1105(2)(aj), Wis. Stats.).

Requirements

  • TID must be created under state law (sec. 66.1105, Wis. Stats.); TIDs created under other sections are not eligible
  • TID's current year value is at least 10% below the TID's base value for two consecutive years (decrement)
    (see TID Statement of Changes Report)
    • The date of the municipality's redetermination resolution determines the two consecutive years
    • Example: if the municipal resolution is adopted May 21, 2023, the 2021 and 2022 values must be 10% below the TID's current base value
  • Only one base value redetermination is allowed during a TID's life

Due date/process

  1. Follow the TID Checklist
  2. Adopt the municipal resolution by September 30 of the amendment year
  3. Notify tif@wisconsin.gov within 60 days after adopting the amendment resolution
  4. Email required documents to tif@wisconsin.gov by October 31 of the amendment year:
  5. Pay the one-time DOR fee in My Tax Account by October 31 of the amendment year
  6. DOR emails a recertification letter before March of the year after the amendment year
    • DOR sets the base value to the equalized value on the date of the municipal resolution

Decrement Determination Examples

Example 1: TID created with a base value = $49,621,600
YearEqualized ValueCalculationDecline
2020
44,595,00044,595,000 - 49,621,600 = -5,026,200 / 49,621,600 =10.13%
2021
44,595,00044,595,000 - 49,621,600 = -5,026,200 / 49,621,600 =10.13%
Value decreased by 10% and was 10% lower for two consecutive years
TID qualifies for a redetermination — new base value is $44,595,000

Example 2: TID created with a base value = $8,113,400
YearEqualized ValueCalculationDecline
2020
6,513,8006,513,800 - 8,113,400 = -1,599,600 / 8,113,400 =19.72%
2021
6,852,6006,852,600 - 8,113,400 = -1,260,800 / 8,113,400 =15.54%
Value decreased by 10% for two consecutive years and met the requirement, even though the TID value increased from 2020 to 2021
TID qualifies for a redetermination — new base value is $6,852,600

Example 3: TID created with a base value = $56,813,200
YearEqualized ValueCalculationDecline
2020
53,843,10053,843,100 - 56,813,200 = -2,970,100 / 56,813,200 =5.23%
2021
49,582,60049,582,600 - 56,813,200 = - 7,230,600 / 56,813,200 =12.73%
TID does not qualify for a redetermination because 2020 TID value had only a 5% decline
If 2022​ results in a decline of at least 10%, the TID would qualify for a base redetermination
