2020 Assessment and Tax Roll XML Schema Changes

  • No schema changes for 2020
  • Reminders from 2019
    • Counties may submit all municipalities at one time using two separate files – one for personal property and one for real property
      • This works best if you send a single zipped folder for each property type
        Image shows a single zip file
      • Make sure the zipped folder only contains xml files
        Image shows a list of xml files
      • Do not include internal folders in your zip file
        Image shows internal folders that should not be included
    • Counties can continue to submit one municipality at a time
    • Send DOR your public (redacted) data to maintain consistency with providing any data
