Michigan Form MI-1040-V is the Individual Income Tax e-file Payment Voucher that taxpayers send to the Michigan Department of Treasury along with a check or money order when they owe a balance on their MI-1040 return. The voucher routes the payment to the correct account, prevents the check from being lost, and stops the state from posting the money to the wrong tax year. Filers who mail a payment without this voucher often see their check held in suspense for weeks, which then triggers automatic penalty and interest billing under the Michigan Income Tax Act.
Owing tax is stressful, but the voucher itself is short and forgiving when handled with care. The Michigan Treasury processes more than 5 million individual income tax returns each year, and roughly 1 in 5 paper payments arrives with a missing or mismatched voucher, the single most common cause of misapplied payments. This guide walks you through the form line by line, with named examples, three full scenarios, and the exact mailing address for the 2025 MI-1040-V (revised 09-25) used for tax year 2025 returns due April 15, 2026.

What the Form Is and Who Must File It
Michigan Form MI-1040-V is a payment voucher, not a tax return. It tells the Michigan Department of Treasury which taxpayer the attached check belongs to, which tax year it applies to, and how much is being paid. The voucher is authorized under the Michigan Income Tax Act, MCL 206.1 et seq., which gives Treasury the power to collect individual income tax and to require identifying information with each payment.
You must file MI-1040-V if you owe a balance on your MI-1040 and you are paying that balance by check or money order through the mail. This includes filers who e-filed their return through the IRS or a paid preparer but chose to mail the payment separately. You do not need MI-1040-V if you pay electronically through Michigan Treasury Online (MTO), if you pay by debit or credit card through the state’s authorized payment processor, or if you set up direct debit from your bank when you e-filed.
The voucher does not apply to City of Detroit returns, which use the separate City Income Tax e-file Payment Voucher (Form 5122). It also does not apply to estimated quarterly payments, which use Form MI-1040ES. Filing the wrong voucher routes your money to the wrong account and forces a manual transfer that can take six to eight weeks. Maria Lopez, a Detroit resident, learned this the hard way when she sent her city tax payment with an MI-1040-V and received a “balance due” notice three months later, even though her check had already cleared.
Before You Start: Documents and Information You Need
Gather everything before you sit down. Stopping mid-form to hunt for a Social Security number is the most common reason filers transpose digits on the voucher. The pre-filing checklist below covers every item Michigan Treasury expects when matching your voucher to your account.
- Your completed MI-1040 return. You need the final balance-due figure from line 33 of your 2025 MI-1040 so the voucher amount matches. A mismatch triggers a manual review.
- Your Social Security number (SSN). Treasury matches the voucher to your account by SSN, not by name. A wrong SSN sends your money to a stranger’s account.
- Your spouse’s SSN if filing jointly. The order on the voucher must match the order on the MI-1040 itself. Reversed SSNs are a top-ten reject reason.
- Your full legal name as it appears on the MI-1040. Nicknames, missing middle initials, or a married name not yet updated with the SSA can hold the payment.
- Your current mailing address. Treasury sends penalty notices and refunds to this address, so an old address may delay or lose correspondence.
- The tax year you are paying. Tax year 2025 returns are due April 15, 2026, and the voucher must say 2025 in the tax year box.
- A check or money order payable to “State of Michigan.” Cash is not accepted by mail, and checks made out to “Michigan Treasury” or “IRS” are returned unprocessed.
- A blue or black ink pen. Treasury’s optical scanners reject pencil, red ink, and gel pens that bleed.
- A windowed or plain #10 envelope and a Forever stamp (or more for heavy mail). Underpaid postage delays the payment past the deadline, which is treated as a late payment.
- A copy machine, scanner, or phone camera. Always keep a copy of the voucher and the front of the check before mailing.
If any item is missing, stop. A voucher mailed without one of these pieces of information is more likely to bounce back or sit in suspense than to post correctly.
Where to Get the Form and How to Access It
The current voucher is the 2025 MI-1040-V (Rev. 09-25), posted on the Michigan Treasury individual income tax forms page. The PDF is fillable on screen, which is the cleanest way to complete it because the typed entries align perfectly with the scanner’s read zones. Print the completed voucher on plain white 8.5” x 11” paper at 100% scale; do not shrink to fit, because shrinking moves the data outside the scanner’s read box.
You can also pick up a paper copy at any Treasury field office in Lansing, Detroit, Sterling Heights, Grand Rapids, or Escanaba, and most public libraries in Michigan stock the form during filing season. If your tax software generated the voucher for you, that printout is acceptable as long as the barcode at the bottom is dark and unsmudged. Marcus Chen, a TurboTax user in Ann Arbor, learned that a faded barcode on a low-toner printer caused his $1,400 payment to post two weeks late.
Do not use a prior-year voucher to pay a current-year balance. The pre-printed tax year and the scanline encode the year, and Treasury’s system will reject or misapply the payment. If you are paying a prior-year balance because you filed late, use that year’s specific MI-1040-V, available in the prior-year forms archive.
Step-by-Step: How to Fill Out MI-1040-V Line by Line
The voucher has only a handful of fields, but each one matters. Use the exact field names and box labels printed on the official 2025 MI-1040-V. Work top to bottom, in blue or black ink, and write inside the boxes. Sample entries below are italicized so you can tell them apart from instructions.
Tax Year Box (Top of Form)
The tax year box asks which year’s tax you are paying. Enter the four-digit calendar year shown on your MI-1040 return — for a 2025 return filed in 2026, write 2025. Print clearly inside the small box at the top right; the scanner reads only this exact spot.
For a fiscal-year filer (rare for individuals), enter the year the fiscal year ends. Janet Pierce, a fiscal-year sole proprietor whose year ends June 30, 2026, writes 2026 in the box.
The most common mistake is writing the year you are mailing the voucher (2026) instead of the tax year you are paying for (2025). The direct consequence is that your check posts to your 2026 estimated account, leaves your 2025 balance unpaid, and triggers a delinquency notice within 60 days. A misconception filers carry is that “the year on my check is what counts.” Treasury ignores the check date for posting; it uses the voucher’s tax year box.
Filer’s First Name, Middle Initial, and Last Name
This field asks for the primary filer’s full legal name. Write your first name, middle initial, and last name exactly as they appear on the first name line of your MI-1040. Use all capital letters if you are completing it by hand, because handwriting in mixed case confuses the scanner.
A specific entry looks like MARIA E LOPEZ in the name boxes. If your name has a suffix such as JR or III, place it after the last name with a single space.
The most common edge case is a recently changed name (marriage, divorce, court order). If the SSA still has your old name on file, use the old name on the voucher and update SSA before next year’s filing. The mistake of using a new married name not yet on file with SSA causes the voucher to fail the name-control match, and Treasury will hold the payment until you respond to a written notice. A misconception is that nicknames are fine; they are not — Bob fails when SSA has ROBERT.
Filer’s Full Social Security Number
This field asks for the primary filer’s nine-digit SSN. Write it in the format 123-45-6789, including the dashes, in the boxes provided. The SSN is the single most important entry on the voucher because Treasury matches the payment to the account by SSN.
For example, MARCUS T CHEN enters 387-22-9041 in the SSN boxes. Double-check against your Social Security card, not from memory.
A nuance arises for taxpayers who use an Individual Taxpayer Identification Number (ITIN). Enter the ITIN in the same field, also in 9XX-XX-XXXX format. The mistake of transposing two digits sends your payment to a stranger’s account, and recovering it requires a written affidavit and can take 90 days. A misconception is that the SSN on the check is enough; the scanner reads only the voucher SSN, not the check.
Spouse’s First Name, Middle Initial, and Last Name (Joint Filers Only)
This field asks for the spouse’s full legal name on a joint return. Complete it only if you filed Married Filing Jointly on your MI-1040. Use the same all-caps format and the same name order as on the return.
A sample entry reads DAVID R LOPEZ. If filing single, head of household, or married filing separately, leave this entire line blank.
The common edge case is a spouse with a different last name. Enter each name exactly as on each spouse’s Social Security card. The mistake of leaving the spouse’s name off a joint payment can cause Treasury to credit only one spouse’s account, which can later trigger a “missing spouse” notice and a refund hold. A misconception is that “we share an account, so one name is enough” — Treasury indexes joint accounts by both SSNs and both names.
Spouse’s Full Social Security Number (Joint Filers Only)
This field asks for the spouse’s nine-digit SSN on a joint return. Enter it in the 123-45-6789 format directly under the spouse’s name, and make sure the order — filer first, spouse second — matches the MI-1040.
For example, joint filers MARIA E LOPEZ (387-22-9041) and DAVID R LOPEZ (412-88-3320) enter Maria’s SSN in the filer box and David’s 412-88-3320 in the spouse box.
The most common edge case is filers who reverse the order from year to year. Pick the order that appears on your MI-1040 and stick with it. The mistake of swapping SSNs causes the payment to post to the secondary spouse’s account, and the primary’s account shows a balance due. A misconception is that “Treasury will figure it out” — the system is automated and will not reorder names without a written request.
Address (Number, Street, and Suite/Apartment)
This field asks for your current mailing address. Enter the street number, street name, and apartment, suite, or unit number on one line, in all caps, exactly as it appears on your MI-1040.
A sample entry reads 4218 W GRAND RIVER AVE APT 7. Use the U.S. Postal Service’s standard abbreviations (AVE, BLVD, ST, RD).
The common nuance is a P.O. Box. If you receive mail at a P.O. Box, enter PO BOX 4218 on the street line and leave the suite line blank. The mistake of using an old address means any Treasury correspondence — including a refund of overpayment — goes to the wrong place and can be returned undeliverable. A misconception is that “the post office will forward it” — Treasury mail is often marked “Do Not Forward,” especially refund checks.
City, State, and ZIP Code
This field asks for the city, two-letter state abbreviation, and five- or nine-digit ZIP code. Enter them in the boxes provided, in all caps.
A sample entry reads DETROIT MI 48202-1843. The nine-digit ZIP is preferred because it speeds Treasury’s mail handling, but a five-digit ZIP is accepted.
For an APO/FPO/DPO address, write the city as APO, FPO, or DPO, the state as AE, AP, or AA, and use the assigned military ZIP. The mistake of writing the full state name (Michigan) instead of the abbreviation (MI) causes the scanner to fail, and your voucher is kicked to manual processing. A misconception is that ZIP+4 is optional everywhere — it is, but adding it cuts processing time in half during peak season.
Amount of Payment
This field asks how much you are paying with the voucher. Enter the dollar amount, with cents, in the boxes on the right side of the form. Do not use a dollar sign, do not use commas, and do not round to whole dollars unless your MI-1040 is rounded.
A sample entry for a $1,247.63 payment looks like 1247.63. The amount must match the check exactly; if the check is for $1,247.63, the voucher must say 1247.63.
The common edge case is a partial payment. You may pay less than the full balance due, but interest and penalty continue to accrue on the unpaid portion under MCL 205.23. The mistake of mismatching the voucher amount and the check amount stops the payment in suspense; Treasury holds it until a clerk reconciles the difference, often weeks later. A misconception is that “the check controls” — the voucher amount is what posts to your account first, and a mismatch triggers manual review.
Signature and Date Lines
The MI-1040-V does not require a signature on the voucher itself; your signature on the MI-1040 covers the payment. There is no date line on the voucher. If your tax software added a signature block, you may sign it, but it is not required by Treasury.
The most common misconception is that an unsigned voucher will be rejected. It will not. Treasury cares about the SSN match, the tax year, and the dollar amount, not a signature on the voucher.
The Check or Money Order Itself
While not part of the voucher, the check is part of the package and is the most-failed step. Make the check payable to “State of Michigan.” Write your last four SSN digits and “2025 MI-1040” in the memo line, like XXXX-9041 2025 MI-1040. Sign the check in blue or black ink, and confirm the numeric and written amounts match.
Do not staple, paperclip, or tape the check to the voucher. Treasury’s mail openers run sheets through high-speed machines that jam on metal. The mistake of stapling the check causes the voucher to tear, the scanner to reject it, and the package to fall to manual handling. A misconception is that “I should staple them so they don’t separate” — Treasury keeps them together by envelope, not by staple.
Three Filled-Out Examples Using Real Scenarios
Below are three complete walkthroughs of named filers. Each table shows what the filer enters in the major fields of the 2025 MI-1040-V.
Scenario 1: W-2 Employee With Under-Withholding (Maria Lopez, Detroit)
Maria is a single nurse who owes $487.20 because her hospital under-withheld after a midyear raise. She e-filed her MI-1040 through TurboTax and is mailing the payment.
| Form Section | What Maria Enters |
|---|---|
| Tax Year Box | 2025 |
| Filer’s First Name, MI, Last Name | MARIA E LOPEZ |
| Filer’s SSN | 387-22-9041 |
| Spouse’s Name | (blank — single filer) |
| Spouse’s SSN | (blank — single filer) |
| Address | 4218 W GRAND RIVER AVE APT 7 |

| Amount of Payment | 487.20 |
| Check Payable To | State of Michigan |
| Memo Line on Check | XXXX-9041 2025 MI-1040 |
Scenario 2: Self-Employed Schedule C Filer (Marcus Chen, Ann Arbor)
Marcus runs a freelance web-design business and owes $3,812.45 because he did not make estimated payments. He files single.
| Form Section | What Marcus Enters |
|---|---|
| Tax Year Box | 2025 |
| Filer’s First Name, MI, Last Name | MARCUS T CHEN |
| Filer’s SSN | 512-66-8807 |
| Spouse’s Name | (blank — single filer) |
| Spouse’s SSN | (blank — single filer) |
| Address | 905 PACKARD ST |

| Amount of Payment | 3812.45 |
| Check Payable To | State of Michigan |
| Memo Line on Check | XXXX-8807 2025 MI-1040 |
Marcus should also review Form MI-2210 because he likely owes an underpayment penalty for skipping estimated payments.
Scenario 3: Retired Joint Filers With Pension Income (Janet and Robert Pierce, Traverse City)
Janet (68) and Robert (71) are retired and owe $1,156.00 on pension and IRA distributions. They filed Married Filing Jointly with Janet listed first on the MI-1040.
| Form Section | What the Pierces Enter |
|---|---|
| Tax Year Box | 2025 |
| Filer’s First Name, MI, Last Name | JANET A PIERCE |
| Filer’s SSN | 281-44-7755 |
| Spouse’s First Name, MI, Last Name | ROBERT L PIERCE |
| Spouse’s SSN | 281-44-2210 |

| Amount of Payment | 1156.00 |
| Check Payable To | State of Michigan |
| Memo Line on Check | XXXX-7755 2025 MI-1040 |
How to File the Completed Form
Mail the MI-1040-V and your check or money order — without staples, paperclips, or your MI-1040 return — to:
Michigan Department of Treasury P.O. Box 30774 Lansing, MI 48929-0774
This address is only for MI-1040-V payments. Do not include your MI-1040 return; returns go to a different P.O. Box listed in the MI-1040 instructions. Use a Forever stamp for a single voucher and check, or weigh the envelope if you include extra documents. The deadline for tax year 2025 is April 15, 2026; if April 15 falls on a weekend or holiday in a future year, the deadline rolls to the next business day.
If you prefer not to mail a check, four electronic options skip the voucher entirely. The first is direct debit through Michigan Treasury Online (MTO), which is free and posts in 1–2 business days. The second is a debit card payment through the state’s authorized processor, which charges a flat fee (around $3.95 in 2026). The third is a credit card payment through the same processor, which charges roughly 2.3% of the payment. The fourth is direct debit scheduled when you e-file through tax software, which is free and lets you pick a debit date up to the deadline. Keep proof of filing in every case: a Certificate of Mailing from USPS for paper, the MTO confirmation number for electronic, or the processor’s emailed receipt for card payments.
What Happens After You File
Treasury opens, scans, and posts the voucher within 7–14 business days during peak season (March through May), and within 3–5 business days the rest of the year. Your check typically clears your bank within that same window. If the check has not cleared after three weeks, call the Treasury Individual Income Tax line at 517-636-4486 before stopping payment, because a stop-payment fee plus a returned-check penalty under MCL 205.19 is far worse than waiting another week.
Once the payment posts, you can confirm it through your MTO account, which shows real-time balance and payment history. If the payment posts but you still see a balance because of penalty or interest, Treasury will mail an Intent to Assess notice with the breakdown. If the payment is misapplied — most often to the wrong tax year — call Treasury and request a journal transfer; they will not move the funds without a verbal or written request from you.
Penalty under Michigan law is 1% per month, capped at 25%, of the unpaid tax, plus interest at a rate set semiannually by Treasury (recent rates have hovered between 8% and 10% APR). Both run from April 15 until the date Treasury receives the payment, so even a partial payment with the voucher reduces the running total.
Mistakes to Avoid When Filling Out the Form
- Writing the wrong tax year in the year box. The payment posts to the wrong year and your real balance stays open.
- Transposing two digits in the SSN. Your money lands in a stranger’s account, and recovery takes up to 90 days.
- Reversing the filer and spouse SSNs on a joint voucher. The primary spouse’s account shows a balance due even after the check clears.
- Stapling the check to the voucher. The scanner rejects torn vouchers, dropping the payment to slow manual processing.
- Mailing the MI-1040 with the voucher. Returns and payments go to different P.O. Boxes; combining them delays both.
- Making the check payable to “IRS” or “Michigan Treasury.” The check is returned, and your payment is treated as never received.
- Using a prior-year voucher. The pre-printed scanline routes the money to the wrong tax year.
- Mismatch between voucher amount and check amount. The payment goes to suspense until a clerk reconciles by hand.
- Using pencil or red ink. The optical scanner cannot read non-standard ink and rejects the voucher.
- Skipping the memo line on the check. A check without an SSN reference is the hardest type of payment to trace if the voucher gets separated.
- Sending cash by mail. Cash is not accepted and will not be returned if lost in transit.
- Underpaying postage. A returned envelope means the payment is late and penalty starts running from April 16.
Do’s and Don’ts
- Do print the voucher at 100% scale on plain white paper — shrinking moves the data outside the scanner’s read box.
- Do use blue or black ink in all caps — it is the only ink the optical scanner reliably reads.
- Do mail the voucher far enough in advance to be postmarked by April 15 — the postmark, not the delivery date, controls timeliness.
- Do keep a photocopy of the voucher and the front of the check — proof of payment if Treasury cannot find your record.
- Do verify the SSN order matches your MI-1040 — a mismatch on a joint return causes posting errors.
- Do call Treasury at 517-636-4486 if the check has not cleared after 21 days — early action prevents penalty escalation.
- Don’t staple, tape, or paperclip the check to the voucher — it tears the form during scanning.
- Don’t include any other forms in the same envelope — the payment P.O. Box is sorted differently than the return P.O. Box.
- Don’t round the amount unless your MI-1040 is rounded — the amounts must match to the cent.
- Don’t use a printout from a prior tax year — the year-specific scanline misroutes the payment.
- Don’t send cash, foreign checks, or starter checks without your printed name — Treasury will not deposit them.
- Don’t assume the post office will forward Treasury mail — most Treasury correspondence is marked “Do Not Forward.”
Pros and Cons of Filing on Your Own vs. With Help
Most filers can complete the MI-1040-V on their own. The voucher is short, and a tax professional adds little value at this stage if the underlying MI-1040 is already done. Still, there are tradeoffs worth weighing before you mail.
Pros of filing on your own:
- Lower cost. No preparer fee on a voucher that takes five minutes to complete — preparers typically bundle voucher prep into their flat fee anyway.
- Faster turnaround. You control when the envelope hits the mailbox; a preparer’s office may sit on it overnight.
- Direct accuracy. You know your own SSN and address better than anyone else, eliminating data-entry errors.
- Privacy. Your name, SSN, and balance stay in your hands rather than crossing a third-party desk.
- Empowerment for next year. Once you fill out one voucher, future ones are routine, even if you owe tax three years in a row.
Cons of filing on your own:
- No second set of eyes. A small typo in the SSN can cause months of headache that a preparer would have caught.
- No reminder system. A CPA tracks deadlines for you; on your own, the April 15 date is yours alone to remember.
- Penalty miscalculation. If you are paying late, a preparer can calculate the exact penalty and interest so you pay once, not twice.
- No representation if Treasury contests. If the payment is misapplied, a preparer with a power of attorney can call Treasury for you under Form 151.
- Limited troubleshooting if the check is lost. A pro has direct lines to Treasury practitioner units that move faster than the public line.
FAQs
Do I need to file MI-1040-V if I e-filed my return?
Yes. If you e-filed your MI-1040 but are mailing a check or money order to pay the balance, you must include MI-1040-V so Treasury can match the payment to your account.
Do I need MI-1040-V if I pay online through MTO?
No. Electronic payments through Michigan Treasury Online identify you automatically, so the paper voucher is unnecessary and should not be sent.
Can I pay by credit card with MI-1040-V?
No. The voucher is for checks and money orders only. Credit and debit card payments go through the state’s authorized third-party processor and skip the voucher.
Should I staple my check to the voucher?
No. Treasury’s high-speed mail openers jam on staples and tear the voucher, dropping your payment into slow manual processing.
What address do I mail MI-1040-V to?
Yes, there is one specific address: Michigan Department of Treasury, P.O. Box 30774, Lansing, MI 48929-0774, used only for MI-1040-V payments.
Can I include my MI-1040 return in the same envelope?
No. Returns and payment vouchers go to different P.O. Boxes, and combining them delays the processing of both.
Whose name goes first on a joint voucher?
Yes, the same name listed first on your MI-1040 must go first on the voucher; reversing the order causes posting errors.
What do I write in Box “Amount of Payment” if I’m paying only part of what I owe?
Yes, partial payments are allowed — write the exact amount of the check, with cents, knowing penalty and interest still accrue on the unpaid balance.
Do I sign the MI-1040-V?
No. The voucher does not require a signature; your signature on the MI-1040 covers the payment.
What tax year do I write if I’m paying for 2025 in April 2026?
Yes, write 2025 in the tax year box because the voucher follows the tax year, not the mailing year.
Can I use last year’s MI-1040-V if I print one off?
No. Each year’s voucher has a year-specific scanline; using last year’s form misroutes your payment.
What if my name changed after marriage but SSA still shows my old name?
Yes, use the old name on the voucher to match SSA records, then update SSA before next year’s filing season.
Is there a penalty for paying after April 15?
Yes. Michigan charges 1% per month (up to 25%) of the unpaid tax plus interest set semiannually under MCL 205.23.
Can I pay with a money order instead of a check?
Yes. Money orders payable to “State of Michigan” are accepted; write your last four SSN digits and “2025 MI-1040” on the memo line just like a check.
