Because Treasury has started issuing the expanded Michigan EITC supplemental check payments for tax year 2022, it is no longer necessary to view or manually update your address. If you moved between last year and now, please be sure your new address is on your 2023 individual income tax return filing.
Treasury: Annual State Individual Income Tax System Maintenance Begins on Friday
December 08, 2023
System maintenance will begin this week in preparation for next year's individual income tax filing season, according to the Michigan Department of Treasury.
Effective after 5 p.m. on Friday, Dec. 8, the state Treasury Department will suspend processing state individual income tax returns due to tax systems being converted for the upcoming 2024 tax filing season. Individuals will be able to file and check the status of returns and receive refunds after Jan. 8, 2024.
Most timely filed refunds for tax year 2022 have been processed.
"I want to thank taxpayers for their patience as we conduct our annual system maintenance in preparation for the 2024 individual income tax filing season," said Deputy State Treasurer Glenn White, who oversees the state Treasury Department's Revenue Services programs. "The processing of tax returns and issuing of refunds will resume in early January. We look forward to serving taxpayers in the new year."
At the close of each calendar year, the Michigan Department of Treasury undergoes system maintenance in preparation for the upcoming individual income tax filing season. The Internal Revenue Service and other states have similar end-of-the-year maintenance schedules.
For the 2023 filing season, the state Treasury Department processed nearly 5.2 million 2022 tax year individual income tax returns, with a typical refund around $760.
Although individual income tax return processing will be suspended until early next year, taxpayers can continue to ask questions through Treasury eServices. The online platform enables taxpayers to ask state income tax-related questions when convenient.
