  • Granting different authority to different representatives takes a separate form for each.
  • You can also email it to DORPOA@wisconsin.gov, or mail it to Mail Stop 5-77, Wisconsin Department of Revenue, PO Box 8949, Madison WI 53708-8949.
  • Questions about the form: 608-266-2486.

Questions

What is the Wisconsin DOR fax number for Form A-222?
