I am filing my taxes and have discovered a peculiarity, when entering my wifes W-2's. We live in Michigan, 100 % of the time. I work in Mi and my wife works across the border in WI. Until this year, her company has always, just taken out MI taxes. This year, her company changed hands and they started taking out taxes in both Mi and Wi. The Mi taxes were the bulk of the deductions, with a small percentage for Wi. While entering the W-2's, it shows I owe the state of Wi taxes due. This has never happened before, and the company always deducted and paid the taxes to the state of MI, our state of residency. Is this something new and do I need to now file a Wi retrurn as well. She has worked in WI well over 25 years and we've never had to file in Wi before.
