Today, Detroit no longer meets the threshold and is trying to get the law changed to permit them to continue to charge the tax.
What logic! People moving out in droves and city wants to continue a tax making it more expensive to live there.
There are a bunch of Michigan cities with less than 1 million in population that charge a city income tax.
For instance: Grand Rapids (pop. 188,000); Muskegon (pop. 40,000)
