How to fill out Form 1040-V (Payment Voucher)
Complete your Form 1040 first

Fill in your personal information
Enter your name, address, and Social Security number on the voucher exactly as they appear on your Form 1040. If filing jointly, include both names and SSNs.
Enter the payment amount
Write the amount you are paying in the payment amount box. This should match the balance due on your Form 1040.
Prepare and mail your payment
Make your check or money order payable to "United States Treasury." Write your SSN, daytime phone number, and "Form 1040" on the payment. Mail the voucher and payment together to the IRS address listed in the instructions for your state.
