While entering my information in the 2024 Michigan software I noticed an error in the calculation of the penalty for those who submit Michigan estimated tax payments that are too low (and thus subject to penalties). Line 25 should be equal to Line 23 multiplied by Line 24 (in my case this is 10%), however, the software is actually multiplying by "10" instead of "0.10", see photo attached. (Yes, I under payed by one whole dollar in the first qtr!)
Note incorrect calculation, should be $0.10
