detroit city tax Anyone else have an issue where working days allocation is not correctly calculating the wages?

I work remotely 40% of the time, so income should be reduced by 40% when I go to the allocation of working days, but my Federal Wages and Detroit Wages remain exactly the same. The adjustment is not adjusting.

Same issue. Need Turbo Tax to respond when they will provide an update or do we need to file manually to Detroit.

I figured it out. The app is not straightforward. Make sure to enter the correct days worked in the city and 260 for days in the year. Then enter your days off plus holiday, those two should not equal 260. Once that is in, you should see the correct calculation.

That did not work. But, go to the Form and Find Form 5121 in the Michigan Forms. Go to Part 3 where the calculation takes place. Column F is the issue and not calculating correctly. Right click on the cell and goto override in the box. You can enter the proper percentage and it should work. Good luck.
