Form 1040-V (Payment Voucher), is an optional form that you can mail the IRS if you're paying your taxes by check.
- If you're paper-filing and paying via check, we'll include your 1040-V with your tax return printout, along with mailing instructions.
- If you're e-filing and paying via check, we'll prepare your 1040-V right after you e-file so you can print it out.
- If you're paying through an installment agreement, you can download the form and mailing instructions from the IRS.
You can omit the 1040-V if you make sure your name, address, Social Security number or ITIN, tax year, related tax form number (like Form 1040), and daytime phone number are on the check.
