The 1040-V is a form you mail with a check or money order to pay federal income tax directly to the IRS
A 1040-V payment voucher is a sheet of paper the IRS sends you when you owe federal income tax and want to pay by mail. It is not a bill — it is a routing slip. You tear it off, attach it to your check or money order, and mail both to the IRS address printed on the voucher. The IRS uses the voucher to match your payment to your tax return and your account.
You only receive a 1040-V if you file a paper tax return and owe money at the end. If you file electronically or owe nothing, the IRS does not send one. If you file on paper and owe tax, the 1040-V comes in the same envelope as your return instructions.
The voucher itself is small — usually a tear-off stub at the bottom of your tax return package. It has your name, address, Social Security number, and the amount you owe printed on it. The IRS uses this information to post your payment to the correct account.
Key Takeaways
- A 1040-V voucher comes with paper tax returns when you owe federal income tax and must be mailed with your payment to the IRS.
- You send the voucher with a check or money order only — the IRS does not accept credit cards or electronic transfers through the mail.
- The voucher includes your name, address, Social Security number, and tax amount so the IRS can match your payment to your account.
- If you file electronically or owe no tax, you will not receive a 1040-V; electronic filers can pay through the IRS website or phone instead.
- Mailing a payment with a 1040-V typically takes 7 to 14 days to reach the IRS, so send it early if your tax deadline is near.
When the IRS sends you a 1040-V
The IRS includes a 1040-V voucher only when specific conditions are met. You must file a paper return (not electronically), and your return must show that you owe tax. If you are due a refund or break even, no voucher arrives.
The voucher comes in the same mailing as your tax return instructions and forms. If you order forms from the IRS by phone or download them from IRS.gov, the 1040-V is included in the package. You do not request it separately — it is automatic for anyone filing Form 1040 on paper who expects to owe.
If you file electronically through tax software or a tax preparer, you will not receive a 1040-V. Electronic filers have other payment options built into the filing process itself.
How to use the 1040-V voucher to pay
The process is straightforward. Tear the voucher off your tax return package along the perforation line. Write your check or money order for the amount shown on the voucher. Do not send cash — the IRS will not process it.
Attach the voucher to the front of your check or money order with tape or a staple. Write your Social Security number on the back of the check as well, even though it is already on the voucher. This creates a second point of identification if the voucher becomes separated from the check.
Place the voucher and check in an envelope and mail to the address printed on the voucher itself. That address changes by state and region, so use the one on your specific voucher, not a general IRS address. The voucher tells you whether to use certified mail or regular mail — follow those instructions.
Keep a copy of the voucher and a record of the check number for your records. If the payment does not post within 30 days of mailing, you will need this information to trace it.
Payment timing and when to mail
The IRS must receive your payment by the tax deadline — typically April 15 — for it to count as on-time. Mailing a check takes 7 to 14 days depending on distance and postal service speed. If your deadline is April 15 and today is April 10, mailing is too risky.
For payments close to the deadline, use an electronic method instead: pay through IRS.gov, call the IRS at 1-800-829-1040, or use an approved payment processor. These methods post immediately or within one business day and do not require a voucher.
If you mail early — say, in February or March — the 1040-V method is reliable. The IRS processes mailed payments and posts them to your account within 2 to 3 weeks of receipt. If you mail on time but the IRS does not receive it, the postmark date on the envelope is your proof of timely mailing, and the IRS will not charge a late penalty.
What happens after you mail the voucher and payment
The IRS receives your envelope, removes the voucher, and scans it to match your payment to your account. The check is deposited into an IRS bank account. This process typically takes 2 to 3 weeks from the date the IRS receives your mail.
You can check the status of your payment on IRS.gov using the "Where's My Refund?" tool, even though you are paying rather than receiving a refund. The tool shows when the IRS received and posted your payment. If you do not see it posted within 30 days of mailing, contact the IRS at 1-800-829-1040 with your check number and voucher copy.
If the check is lost in the mail, the IRS will not charge you a penalty as long as you can show the postmark date. You will need to stop payment on the original check and mail a new one with a new voucher, or use an electronic payment method to pay the remaining balance.
Why use a 1040-V instead of other payment methods
Most people do not choose the 1040-V — they use it because they file on paper. If you file electronically, you have faster and more reliable options: paying through IRS.gov, using a payment processor, or paying by phone. These methods post within one business day and you get immediate confirmation.
The 1040-V is useful only if you prefer to file on paper and want to pay by check or money order. It is free, requires no credit card, and creates a paper trail. But it is slow compared to electronic payment, and if the mail is delayed, you risk missing the deadline.
If you file on paper but want to pay faster, you can still use electronic payment methods. You do not have to use the 1040-V just because you received one. Pay through IRS.gov, by phone, or through an approved payment processor instead — all of these work whether you filed on paper or electronically.
Common mistakes with the 1040-V voucher
The most common error is mailing the payment without the voucher. The IRS can still match the payment to your account if your check has your Social Security number on it, but it takes longer and may cause delays in posting. Always attach the voucher.
Another mistake is sending cash. The IRS will not process it, and you will lose the money. Use a check or money order only.
A third error is using the wrong mailing address. The address on your specific voucher is the correct one — do not use a general IRS address you find online. Each region has a different address, and mailing to the wrong one delays processing.
Finally, do not mail the payment too close to the deadline. If April 15 is fewer than 10 days away, use electronic payment instead. A mailed check that arrives on April 16 is late, even if you mailed it on time.
Frequently Asked Questions
Do I have to use the 1040-V voucher if I received one?
No. The voucher is optional. If you file on paper but want to pay faster, you can pay through IRS.gov, by phone at 1-800-829-1040, or through an approved payment processor. These methods post within one business day and do not require a voucher.
What if I lost the 1040-V voucher?
You can still mail a payment, but include your Social Security number, tax year, and the amount owed on a separate sheet of paper. The IRS will match it to your account. However, using electronic payment is faster and more reliable if you have already lost the voucher.
Can I pay with a credit card using the 1040-V voucher?
No. The 1040-V voucher is for checks and money orders only. If you want to pay by credit card, you must use an approved payment processor through IRS.gov. These processors charge a fee, typically 1.87% to 2.35% of the amount paid.
How do I know if my mailed payment was received?
Check the status on IRS.gov using the payment tracking tool, or call 1-800-829-1040 with your check number and voucher copy. The IRS typically posts mailed payments within 2 to 3 weeks of receipt. If you do not see it posted within 30 days of mailing, contact the IRS to trace it.
What if my check bounces after I mail it with the 1040-V?
The IRS will attempt to deposit the check. If it bounces, the IRS will send you a notice demanding payment plus a penalty for the returned check. Pay immediately by electronic methods to avoid additional penalties and interest charges.
