MARQUETTE – Taxpayers have about a month to file their state individual income tax return, according to the Michigan Department of Treasury.

State individual income tax returns must be filed electronically or postmarked through the U.S. Postal Service by 11:59 p.m. on Wednesday, April 15. For more information about e-filing, go to www.mifastfile.org.

“We are just about at the halfway point of the filing season,” said Deputy State Treasurer Kavita Kale, who oversees Treasury’s Revenue Services programs. “Taxpayers still have plenty of time to file their state individual income tax returns. For the most accurate returns, consider electronic filing or using a reputable preparer. Taking time out of your schedule and filing today ensures you receive all the tax credits and deductions you are entitled to receive.”

To date, more than 2.4 million returns have been processed, providing more than $1.43 billion in refunds.

For the benefit and convenience of taxpayers, both federal and state of Michigan individual income tax returns are due April 15, 2026. Taxpayers who owe tax must make outstanding payments by April 15, 2026.

“We appreciate the public’s patience during this unusually busy period and encourage taxpayers to carefully review their returns before filing to help reduce errors,” Kale added.
