Transmitting Electronic Returns - Software Developer Specifications for ST-12
The Wisconsin Department of Revenue currently offers two methods of transmitting ST-12's.
- HTTPS upload. You navigate to our ST-12 page and use the Ready to Transfer button, identify your file and click an upload button. Be sure to identify whether this is a test file by checking the appropriate radio button. Upon a successful transfer you will receive a receipt number, we will then email the acknowledgement to the email address you included in the AckAddress element in the electronic ST-12.
- REST web transfer. This will require you (or your software vendor) to write code to make the transfer. REST is like a web Service but without using the SOAP protocol. Upon a successful transfer you will receive a receipt number, we will then email the acknowledgement to the email address included in the AckAddress element in the electronic ST-12. Please contact your DOR representative for the proper URL and other pertinent information about programming for a REST transfer.
