🚨🚨🚨🚨 State Refund
FYI
As of April 2026, the Michigan Department of Treasury is addressing a widespread "glitch" involving incorrect tax adjustment notices sent to numerous residents. This issue is occurring alongside significant delays in refund processing due to a major system transition.
The "Notice of Adjustment" Glitch
The Issue: Many taxpayers have recently received "Notice of Adjustment" letters that incorrectly claim they owe additional money or that their refunds have been reduced.
Cause: Reports from tax professionals indicate the glitch is "fairly widespread" and stems from the Treasury's implementation of a new processing system.
Action Required: If you receive a notice that seems incorrect, verify your status through the official Michigan Treasury eService portal. Do not immediately pay a demanded balance without verifying its accuracy.
Refund Status "Pending Review"
Many filers are seeing their refund status stuck in "Pending Review" or "Manual Review" for 6–8 weeks or longer.
System Transition: The state is moving to a new software platform, which has slowed down real-time status updates.
Common Flagged Credits: Returns containing the Home Heating Credit or the Earned Income Tax Credit are facing longer processing times as they require extra verification.
Identity Verification: You may receive a letter asking you to complete an Identity Confirmation Quiz. This is a legitimate security step; your refund will not proceed until this is completed on the official Michigan Treasury site.
Alert: Scam Letters and Texts
The Department of Treasury has warned of high-quality scam letters circulating during this glitch.
Red Flags: Letters that use aggressive language, threaten immediate property seizure, or provide an unofficial toll-free number for payment are likely scams.
Verification: The official customer service number for individual income tax questions is 517-636-4486.
Text Scams: The state does not send text messages regarding tax debts or refunds. If you receive a text with a link, it is a phishing attempt.
