BEWARE OF UW-STOUT or any college within the University of Wisconsin system! I withdrew from the online graduate program due to a medical issue during the withdrawal period. UW-Stout charged me $3,000 without written notice until I received a letter 1 year later from the Wisconsin Department of Revenue. Apparently, UW-Stout turn outstanding student balances over to the Dept of Revenue in order to collect the debt as a tax so they can garnish your income tax refund (or wages) if you cannot afford a payment plan. How is this legal?
