If you are an existing e-Services user and you cannot successfully authenticate online, you have an option called exception processing by phone. You may call the IRS and a customer service representative will ask a series of questions related to your current and prior year tax return information including income information documents. For exception processing, call the e-Help desk at 1-888-841-4648 (select your language, then prompt 1 and remain on the line until an assistor picks up) 7:30 a.m. Eastern to 7 p.m. Eastern.
