To allow Detroit to continue to uniquely impose an income tax of 2.5 percent on residents and 1.25 percent on nonresidents. Other cities are allowed to impose individual income taxes at 1 percent for residents and 0.5 percent for non-residents; this is one of many laws that provides unique privileges or powers for "a city with a population greater than 750,000." The bill would lower that to 600,000 to accommodate Detroit's ongoing population decline.
