I thought I paid my federal taxes on-line with my credit card. It isn't showing up on my account. Do I need to send a check?

If you believe the credit card payment didn't go through you can try again to pay online at https://www.irs.gov/payments.

Otherwise you would need to mail a check or money order for the Federal taxes due. You would need to include the Form 1040-V payment voucher with  your payment. The voucher would be included in your printed tax return. You can also obtain the voucher at the following website https://www.irs.gov/pub/irs-pdf/f1040v.pdf (mailing instructions found on page 2).

 Make your check or money order payable to “United States Treasury. Make sure your name and address appear on your check or money order.

 Also be sure to enter your daytime phone number and your SSN on your check or money order. If you have an Individual Taxpayer Identification Number (ITIN), enter it wherever your SSN is requested. If you are filing a joint return, enter the SSN shown first on your return. Also enter “2016 Form 1040,” “2016 Form 1040A,” “2016 Form 1040EZ,” or “2016 Form 1040NR,” whichever is appropriate.
