Guidelines for Warranted Changes

  • If DOR determines any changes to the preliminary values are warranted, we will make the changes before certifying the values
  • DOR will make changes to preliminary values following these thresholds:
    • Greater than 2% of the Equalized Value or TID Value – will adjust the 2023 value
    • 2% or less of the Equalized Value or TID Value – will make an adjustment to the 2024 value
    • We will not apply value changes resulting from an amended Municipal Assessment Report (MAR) filed after the second Monday in June. These changes will become an adjustment to the 2024 Equalized Value.
    • If necessary, DOR will contact the municipal assessor to discuss and confirm changes
