Legal teams at some of the "Big Box" stores have been successful in getting the state of Michigan to refund large chunks of property tax dollars, and that has some local governments facing some big shortfalls.   63rd State Rep. Dave Maturen has been charged with looking into the issue to see what changes the state might propose to the sytem.   It's a complicated issue.   Businesses pay property tax based on the cost paid to buy land and build a facility.   But many are convincing the Tax Tribunal in Lansing to reduce it, based on the value of an empty, abandoned store.   Rep. Maturen joined WBCK's Tim Collins on the Richard Piet Show on Monday morning.
