(From Yahoo Finance)
In Wisconsin, the state is expected to take a tax bite equal to 7.65 percent or the top tax rate, deducting another $36.5 million.
That brings the overall tax tab up to about $213 million. From the lump sum value of $477 million, this would mean the take home pay is around $264 million.
