Attachment A

Acknowledgement of Risk with Email

I acknowledge that there are risks associated with email, such as the possibility that sensitive taxpayer information could be intercepted and viewed by unauthorized persons. I understand the importance of securing email using appropriate encryption, particularly when transmitting sensitive or confidential tax-related information. I understand that SecureZIP and compatible utilities only encrypt the email attachment and not the subject line or the body of the email itself, and that confidential information should not be included in the subject line, the body of the email itself, or the file name of the attachment. By signing this agreement, I understand that sensitive or confidential information should be sent only by compressed and encrypted email attachments in communicating with the IRS.

Even with encryption it is possible electronic communications could be intercepted. I acknowledge that the United States Government does not guarantee the security of data transmitted electronically by email and accepts no liability, regardless of fault, for any loss or damage sustained without negligence of United States Government employees.

(Name of Taxpayer) (Title of Individual Signing Acknowledgment)

*SIGNATURE: _______________________________

DATE: _______________________________

*Signature must be from any person who could sign the return of the taxpayer, not a representative. If the taxpayer is a corporation, the signature must be from an officer of the corporation.
