To: Municipal Clerks and Treasurers

The Wisconsin Department of Revenue (DOR) posted the 2018 Statement of Assessment (SOA) on our website. You must electronically file (e-file) the SOA using our e-file form or file transfer.


General form information

  • Due date: June 11, 2018 or after your Board of Review (BOR)
  • You do not need to inform us if your BOR is held after June 11, 2018
  • Assessed values:
    • SOA is a summary of each district's assessed value (real and personal property)
    • Provide an assessed value for each district, even if it has no tax levy
  • SOA also includes parcel counts and acreage of exempt real property

2018 form updates

  • Reporting of locally assessed personal property – machinery, tools and patterns is no longer required (Sec. B, Line 12)
  • The managed forest lands rates were updated for 2018

File transfer

  • Your text file must follow the current SOA File Layout
  • DOR cannot process files with incorrect district codes
  • Do not include manufacturing values in your file
  • You must include the assessor name and accurate phone number
  • Receipt number is confirmation your file was sent to DOR. If we are unable to process it, we will contact you.

Why is accurate filing important?

  • DOR uses SOA values to certify school district, technical college and special district Equalized Values; this process begins September 1
  • If we do not receive a completed SOA, we will estimate the assessment data based on the prior year SOA values
  • DOR posts all final SOAs on our website. After a final SOA is posted, you may still amend it, if needed. However, we will not update the final SOA on our website or calculate a new aggregate ratio.
  • If you submit an amended SOA, DOR will process it and you should use the corrected values to calculate tax rates
