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 percent of the Equalized Value or TID Value – will adjust the 2017 value
    • 2 percent or less of the Equalized Value or TID Value – will make an adjustment to the 2018 value
    • We will not apply value changes resulting from an amended Municipal Assessment Report (MAR) or Tax Incremental District Report (TAR) filed after the second Monday in June. These changes will become an adjustment to the 2018 Equalized Value.
    • If necessary, DOR will contact the municipal assessor to discuss and confirm changes


  • August 7 – Deadline for municipalities to contact an Equalization Bureau District Office about the preliminary values
  • August 15 – DOR will publish the 2017 Final Equalized Values, TID Values, Net New Construction Report and County Apportionment Report, and notify stakeholders
