LANSING, Mich. – With taxpayers required to either e-file or mail their state individual income tax returns by midnight tonight, the Michigan Department of Treasury (Treasury) has some tips to help last-minute filers submit an accurate return.

To ensure an accurate income tax return is filed with the state of Michigan:

• File electronically. Taxpayers can go to www.michigan.gov/mifastfile to learn more about e-filing options.  
• Mail a paper return to the right address. To avoid processing delays, paper filers should carefully follow tax form instructions when sending a paper return to a specific address.
• Fill in all requested information. When entering information on the tax return, take the time to ensure information is accurate. Information on paper returns should be legible and easy to read.  
• Review all figures. While software catches and prevents many errors on e-filed returns, math errors remain common on paper returns.  
• Get the right routing and account numbers. Requesting direct deposit of a state tax refund is convenient and enables the taxpayer to access their money faster. Make sure the financial institution's routing and account numbers entered on the return are accurate.  
• Sign and date the return. If paper filing a joint return, both spouses must sign and date the return. Most e-file software platforms allow electronic signatures.  
• Submit all the required forms. Paper filers should carefully follow the instructions and attach all forms as indicated. If possible, use a paperclip, binder clip or rubber band to hold all documents together.  
• Owe tax? Taxpayers can pay their outstanding tax balance by check, money order, eCheck, debit or credit card.

Need an extension?

Individual taxpayers who need additional time to file a return beyond the April 18 deadline can request an extension to Oct. 16, 2023. Taxpayers can request additional time to file by using MI Form 4, Instructions for Application for Extension of Time to File Michigan Tax Returns.

Taxpayers requesting additional time to file should also estimate their tax liability and pay any taxes owed by April 18, 2023, to avoid additional interest and penalties. An extension to file is not an extension to pay.

Michigan taxpayers who have questions about or need help with their individual income tax returns or refunds can digitally connect with the state Treasury Department through its Treasury eServices platform. In addition, taxpayers can call the Treasury Customer Contact Center at 517-636-4486.
