Treasury is aware of concerns regarding notices and returns processing and we are committed to addressing these problems directly and transparently.

We fully recognize the frustration this situation has created for both tax preparers and taxpayers. In addition, we understand many tax preparers are bearing the brunt of taxpayer frustration, and for that, we apologize.

Although these issues are limited in scope, this situation is frustrating and disappointing to us all. The transition from our 40-year-old legacy system to the modernized system (used by many other states) was successful, with fewer than 4% of the 5 million returns affected by the issues identified. The new system allows for a more effective and efficient administration of Michigan’s Individual Income Tax.

However, we recognize it comes with opportunities for improvement and we appreciate your patience as we work through them. Your feedback directly informs the corrective work we are prioritizing.

Here are the steps Treasury is taking to respond:

We have created a Solution Tracker to document known issues, their status, and planned resolutions. This will help us stay aligned, keep you informed, and ensure accountability across teams.
We are actively making changes and corrections as issues are brought to us. Several updates have already been implemented, and additional changes, including a review of all letters prior to the next tax season, are in process based on practitioner feedback and internal review.
Customer service capacity has been evaluated, and we have implemented a Request for Call Back feature within Michigan Treasury eServices so we can connect with taxpayers who have been unable to get through . Our goal is to respond to these requests within 3 business days. Treasury’s new phone system with increased capacity and customer service enhancements will be launched in July.
We understand that the cumulative impact of these issues has eroded trust, and rebuilding that trust will take consistent action and open communication. Your partnership is essential in that process. Your feedback directly informs the corrective work we are prioritizing.

We will continue to update the Solutions Tracker as concerns or issues are identified.

Update on Recent Taxpayer Correspondence
Michigan Department of Treasury sent this bulletin at 04/29/2026 08:45 AM EDT

Treasury Update
Taxpayer Correspondence Issue
Good morning, Tax Professionals,

Thank you for bringing recent taxpayer letter concerns to our attention so quickly. We want to acknowledge that an error occurred in certain letters related to estimated payments and credit carryforwards, and we sincerely apologize for the confusion this has caused.

As we were adjusting our new system to improve efficiency, an unintended issue was introduced that affected the way information was displayed in these letters. Importantly, taxpayer prepayments are properly accounted for and reflected correctly in Michigan Treasury eServices.

To use Michigan Treasury eServices, visit www.michigan.gov/mitreasuryeservices. For individual income tax, taxpayers will access the MiTreasury eServices – Citizen portal and tax professionals will access the MiTreasury eServices - Business portal.

Taxpayers do not need to take any action currently. Corrected letters will be issued once we confirm the system is functioning as intended and we have accurately identified all impacted taxpayers, which we expect will be before these taxpayers' appeal rights expire. If a taxpayer disagrees with their notice and has not received a correction before appeal rights expire as stated on the original letter, they should exercise their right to appeal.

We currently believe the issue is limited to letters dated between April 7–28, 2026. Although Treasury stopped sending these letters on April 20, some taxpayers may continue to receive them as they move through the postal system.

If there are concerns regarding letters outside of the date range above, or unrelated to prepayments and credit carryforwards, please respond to the letter as instructed using Michigan Treasury eServices or US Mail.

We are grateful to our association partners for alerting us promptly and sharing detailed information. Your responsiveness allowed us to identify the issue quickly and begin the resolution process. The Tax Year 2025 Return Processing Updates webpage now includes a link to a solution tracker which captures known issues and their status. I hope this is helpful for you and your clients.

Thank you for being a valued partner.

Sincerely,

Kavita Kale
Deputy Treasurer of Revenue Services
