MARQUETTE — The Michigan Department of Treasury has announced that 95% of individual income tax returns have been completed for the filing season, representing a key milestone for the tax filing season that opened on Jan. 26.

The 95% achievement represents that most tax returns received before the April 15 filing deadline have been processed. As of June 8, Treasury processed more than 5.12 million individual income tax returns and issued over $3.43 billion in refunds since the filing season opened on January 26. The average refund was $901.

“I want to thank our taxpayers and tax professionals for their patience during individual income tax season,” said Deputy State Treasurer Kavita Kale, who oversees Treasury Revenue Services service area. “The Michigan Department of Treasury replaced a 40-year-old legacy system with a modern, commercial off-the-shelf product capable of doing end-to-end tax administration. This was the equivalent of moving from a landline phone to a smart phone. The 95% milestone is an important benchmark for processing returns and matches year-to-date progress compared to previous years.”
