To electronically file a Wisconsin fiduciary income tax return for an estate or trust, you can either:

  • Use the department's free Wisconsin e-file application; or
  • Purchase and use third-party software.

While the department does not charge for electronic filing of tax returns, third-party vendors typically charge a fee for their software products and services. These products vary in price and features. Filers should keep in mind:

  • Software is supplied directly by the developer of that software, not the Wisconsin Department of Revenue. In most cases, you can download or purchase software from an Internet site and pay with a credit card.
  • The purchase price of the software may or may not include preparation of the returns. Electronic filing of your returns may require that you pay an additional fee to the software vendor at the time of filing.
  • Filers should keep a copy of the return and acknowledgement for their records.

Approved Vendor List

These sites are approved by the Wisconsin Department of Revenue (DOR). Their software products have been tested to ensure DOR can receive and process the tax return; however, DOR does not guarantee any aspect of the software, its features or performance. Please make sure the software vendor company supports all of the forms and schedules you need to electronically file your fiduciary, estate or trust tax return.
