C-2423 Fax Transport
Revision 24-3; Effective Sept. 1, 2024
All Programs
Fax machines must be placed in a secure area and staff should refrain from faxing FTI, when possible. There must be trusted staff at both the sending and receiving fax machines. When faxing is required, staff must use Form H1864. The form must accompany all faxed documents that contain IRS data when transferred from one office to another or from an office to a banking institution for verification purposes. The sender ensures the receiver acknowledges the receipt of the information and retains this form for five years.
