Somebody could be holding a bunch of money for you, but it’s going away if you don’t beat the deadline. If you haven’t filed taxes in a few years, I-R-S spokesman Christopher Miller says you may have a tax refund waiting for you. Estimates are that almost 22-thousand people in Wisconsin could still get about 20-million dollars in unclaimed refunds. The deadline is April 18th. Miller says that’s when the three-year window to claim the refund money closes. The average refund will be about 750-dollars.
