LANSING, MI — State income tax returns are due in less than a month, a press release from The Michigan Department of Treasury noted on Monday.

State income tax returns must be submitted electronically or postmarked through the U.S. Postal Service by 11:59 p.m. on Monday, April 15, the release said.

“The end of tax season is quickly approaching,” said Deputy State Treasurer Glenn White, who oversees treasury’s tax administration programs. “To avoid delays or penalties for late filing, we encourage all taxpayers to file their Michigan taxes before the deadline.”

Utilizing electronic filing and direct deposit is fast, safe and secure, the press release said. Last year more than 4.2 million Michigan taxpayers e-filed, which accounts for nearly 85 percent overall.

Printed tax forms are available at public libraries, post offices in northern Michigan and the Upper Peninsula, Department of Health and Human Services county offices, and treasury field offices.

For the convenience of taxpayers, both federal and state tax returns are due on Monday, April 15.
