Form WT-7 Electronic Filing Mandate - 3 Options

All employers and preparers are required to electronically file their Employer's Annual Reconciliation of Wisconsin Income Tax Withheld From Wages (Form WT-7) with one of three options:

My Tax Account -- Our free online business tax service. If you already use My Tax Account, you will see the WT-7 labeled as the Tax Year 20XX period under your withholding account on the WT-7 Reconciliation Tab. Learn how to register for My Tax Account.

Telefile -- Enter your WT-7 information using a touch tone phone. Call TeleFile using a touch tone phone: 608-261-5340 (Madison) or 414-227-3895 (Milwaukee).

eFile Transmission -- This option is for employers who have purchased commercial software for preparing the Form WT-7 or tax preparers who have programmed their own software to our specifications.

You can find more information about how to electronically file your Form W-2s on our Form W-2 Data File Transfer web page and on My Tax Account.

Note: We do not support electronic filing of PDF versions of Form WT-7s.
