Why am I selected for review and/or receive a Letter of Inquiry every year?

Why am I selected for review and/or receive a Letter of Inquiry every year?

All returns are subject to a manual review by the Michigan Department of Treasury. 

Selection for review one tax year does not increase or decrease the chance of your return being selected in future years.

Michigan law prevents the Department from discussing specific criteria for review of returns. If the review results in an adjustment to your return, you will receive a letter of explanation.
