Penalty Payment Refunds

Issue: Taxpayers who filed estimated payments and included the penalties for underpayment with their return may have received a refund equal to that penalty.

Solution Tracker

If a taxpayer receives an unexpected payment from Treasury – whether in the form of a check or direct deposit – they should return that payment and notify us via Michigan Treasury eServices.

Taxpayers can also use Michigan Treasury eServices to determine if they have an amount due. Notice of Assessments will be sent in the coming weeks, if the penalty payment has not been received prior to assessments being issued.

To return a payment to Treasury, mail the uncashed check and a statement on why you are returning the check such as “Treasury issued in error” back to Treasury at:
