The high-octane political fight over taxes at the Capitol got a new source of fuel Wednesday: a statewide study that finds lower- and middle-income households are hit hardest by Minnesota's tax system.
"Minnesota's tax system is more regressive than it was a decade ago," acting Revenue Commissioner Dan Salomone said Wednesday. "Despite a slight improvement over the last study, the system remains notably more regressive than the historical average since 1991."
The study found that 90 percent of the state's earners paid an average of 12.3 percent of their income in state and local taxes in 2008. The wealthiest 10 percent of households earning more than $130,000 paid an average of 10.3 percent.
The study also found the gap between top earners and the rest of the population has widened over the past decade and that local property taxes -- a highly regressive tax -- make up a larger share of the overall tax mix.
Minnesota House Speaker Kurt Zellers said the message to him is that elected leaders unwisely raised sales and gas taxes in recent years. He said it also strengthens Republicans' call to cut income tax rates.
Zellers, R-Maple Grove, said the answer is to lower taxes on those shouldering most of the burden rather than raising them at the high end.
The findings come just as the Republican-controlled Legislature is preparing steep cuts to local government aid, which DFL Gov. Mark Dayton says will trigger further property tax increases.
But in a sign that they can only go so far, Republicans appeared Wednesday to be caving to pressure from suburban leaders upset about proposed aid cuts.
