To: Trusted E-Service RETR software providers

The Wisconsin Department of Revenue (DOR), State and Local Finance Division is making enhancements and upgrades to our Real Estate Transfer Return (RETR) application, which rolls out in early 2025.

XML – RETR Data File (Schema) Information

As part of this upgrade, DOR will publish a new XML RETR data file schema in the near future, which will apply business rules for our new online RETR filing system.

RETRV​0.3 schema package will contain:

• RealEstateTransferReturn.xsd – this is the schema
• Sample1.xml – XML sample that validates properly against the schema
• Documentation folder – containing:
• RETR Types.xlsx – spreadsheet with information on enumeration values in the schema
• RETR_Documentation.doc – general documentation for the schema. (Note: This is a reference document and is intended to be searched, but not read cover to cover)

Next steps – DOR will:

• Provide the new RETR schema to software providers who currently offer the ability to file RETRs with DOR using their software
• We'll inform you when the new schema package is published and available
• DOR will answer questions about the new schema
• Ask software providers to test file transmissions with DOR
• When DOR has the testing endpoints set up, we'll communicate that with you – allowing you to test the new schema
• If there are updates during DOR testing – we'll notify you of the updated schema
• Note: You will receive an acknowledgement from each test WISDAL informing you whether the test file worked
• Provide the production end points when enabled – closer to January 2025
