Schema Information

2021 Summary of Changes

  • No schema changes for 2021
  • Reminders:
    • Counties may submit all municipalities at one time using two separate files – one for personal property and one for real property
    • Counties can continue to submit one municipality at a time
    • Send DOR your public (redacted) data to maintain consistency with providing any data

Prepare the File

  • Name each file with its corresponding DOR Co-muni code – to improve the file names and quickly identify which file belongs to a specific municipality
  • Upload one municipality at a time – to make the file easier to locate when working together to troubleshoot issues
  • Upload one county at a time - send a zip file with all municipality files included
    • Send a single zipped folder for each property type
    • Make sure the zipped folder only contains xml files
    • Do not include internal folders in your zip file

DOR Review

  • Test files are processed individually
  • To help us respond to questions, DOR's acknowledgement email contains the file name as it is stored in our system

If you have any questions, contact us at OTAS@wisconsin.gov or (608) 266-7750.
