Requesting AGI from the IRS
If you don't have your tax return from the prior year, you can call the IRS at 800-829-1040 to verify your AGI from the prior year. Alternatively, you can request a free copy of a transcript of your tax return from the prior year to check your AGI. To order a transcript, call the IRS at 800-908-9946 or go to the IRS website to view your transcript online or order a copy by mail. You must provide your name, date of birth, Social Security number, filing status from your last return and address from your last return.
