Due to an error on our e-file submission, the IRS rejected the final tax payment sent with a 1040. For various reasons, we DO NOT want to now pay electronically...we need to send a paper check. I can find instructions on the IRS website about a 1040-V (and where to mail it). My question is, since the return was already sent and accepted electronically (except for the payment), do we need to send the entire 1040 (and attachments) at this point, or just the 1040-V + paper check?
You only mail the Form 1040-V and your check for the federal taxes owed.
just the 1040-V and payment. follow the instructions for the info that needs to be on the check so it is applied to your a/c. mailing will result in further delay which may increase the penalties and interest for late payment. send by a method where you get proof of delivery. there have been some horror stories lately of undelivered mailed by the USPS. in addition, the USPS postmaster general has ordered workers not to work overtime to deliver the mail.
