More Wisconsin taxpayers could take advantage of free on-line tax filing. Merideth Helgerson with the Wisconsin Department of Revenue says FreeFile is an electronic option for Wisconsin taxpayers, to file their state taxes for free. About 100,000 individual returns came through the state's FreeFile system last year, so there's plenty of potential for more people to take advantage of it. And you can get your return in as little as three to five days, another good reason to do FreeFile. If you have a tax preparer do your taxes for you, chances are they're already filing electronically
