LANSING — A delay in changing the tax math for big-box stores could cost local governments big bucks for generations, say supporters of a bill that would stop the stores from claiming big tax breaks. “That’s the really scary thing,” said Greg Seppanen, a former Marquette County commissioner fighting low tax assessments as part of the county’s Citizens for Fair Share. The Michigan Tax Tribunal hears appeals from taxpayers who think their municipality has over-assessed the value of their property. In 2013, the tribunal agreed with a big-box store that said the value of its property had more to do with their business and less to do with property characteristics. This ushered in a wave of big-box stores demanding tax breaks and pointing to vacant big-box stores as evidence that local governments were overcharging them.
