Withholding WT-6 and Batch Payments Electronic File Transmission

The Wisconsin Department of Revenue is pleased to offer employers the option of paying via this secure Internet process. Employers, and/or their representatives, transmit payment data in an electronic file over the Internet.

This file allows employers to send an electronic funds transfer (EFT) for the full amount of payment along with the information necessary to identify the amount that is credited to each individual employee.
