Form 1040-V is a payment voucher used with Forms 1040, 1040A, and 1040EZ. If you have a balance due, send a 1040-V with your payment to speed processing.

Don't send cash for payments to the IRS. If paying by check:

• Make the check payable to the “U.S. Treasury.”
• Make sure your name and address are on the check.
• In the check’s memo section, write:
  • Form number you’re filing:
    • “2012 Form 1040”
    • “2012 Form 1040A”
    • “2012 Form 1040EZ”
  • Daytime phone number
  • Social Security number (SSN). If filing a joint return, write the first SSN shown on the return.
• When writing the payment amount on the right side of the check, write the number like this: $XXX.XX. Don’t use a dash or slash ("$XXX-" or "xx / 100").
