At a very high level, assuming you itemize, it depends on your marginal tax rate. Most people will be in a (combined Federal and Minnesota) 30%+ marginal tax rate. For example, the 25% federal tax bracket for married couples starts at $73,800, which puts you at ~ a 7% Minnesota tax bracket, for a total of 32%. The 28% federal tax bracket for married couples starts at $148,850, which puts you in ~ an 8% Minnesota tax bracket, for a total of 36%. The tax brackets reach a combined 49.45% for the highest earning individuals. The tax brackets can be found in multiple spots online. Hope that helps.
