Received a Letter of Adjustment from Michigan Department of Treasury. They zeroed out my 2025 form 4884 retirement and pension benefits subtraction. The letter provided no reason for the adjustment, just the adjustment to zero and the following collator adjustments due to that change, zeroing out our refund and ending with a balance due.
I have completely reviewed my 2025 Michigan Income Tax Return and found no errors.
Curious if anyone knows the reason for this adjustment or if this is happening to many people from Michigan.
