Why do I need last years adjusted gross income (AGI) to e-file?
The IRS requires that taxpayers who e-file a return to enter the adjusted gross income from the prior year return. This is how the IRS confirms your identity. If you cannot provide last year’s return, or you can’t find your AGI, you can call the IRS at 800-829-1040. You must provide some identifying information to the IRS, such as Social Security number, in order to receive your prior AGI by phone.
