Who can use Secure Messaging?

Individuals and authorized employees of your company will be able to use secure messaging relating to your LB&I case. You will interact directly with a LB&I representative.

How Secure Messaging works

IRS Secure Messaging is similar to a web-based email service. Messages can be securely sent to you by IRS representatives and you may respond and include document attachments pertaining to your LB&I case.

The IRS will save all messages as a digital record of your communications with us. You'll be notified when you have a secure message waiting for you via a notification email to the address(s) provided on the signed consent.

The notification will include a link to your secure messaging center. In order to protect your privacy and reduce the potential for identity theft, we will send no personal information within the notification email.
