Living in Pontiac MI but working in Detroit MI

You will pay 1.20% to Detroit and 1% to Pontiac.  If you lived and worked in Detroit, you would pay 2.4% to Detroit.

Thanks. Is this calculated from Adjusted Gross Income?

No,, the Detroit city tax return applies to compensation for work done in the city for nonresidents.  The Pontiac MI resident tax return does not use the Adjusted Gross Income.   @FM23
