Where to mail your Michigan state tax return

Key facts

• Michigan splits paper Form MI-1040 returns by address: return with payment (tax owed) vs. return without payment (refund, credit, or zero due) — mailing to the wrong one can delay processing.
• Make checks or money orders payable to the "Michigan Department of Treasury".
• These two addresses have no street line — like the IRS, Michigan routes them on the dedicated ZIP code alone.
• A mailed return is generally considered filed on time if it is postmarked by the state filing deadline — sign and date it, since an unsigned return isn't considered filed.
• PostPal prints your return and hands it to USPS the next business day for $5 — no printer, envelope, or trip to the post office.
