Check your most recent tax return
Look for the line labeled “Adjusted Gross Income” or “AGI”
Use the AGI from your prior-year federal tax return
If you filed electronically, review your tax software or IRS e-file confirmation
If you filed on paper, check Form 1040, line 11
If you amended your return, use the AGI from the original return unless instructed otherwise
If you cannot find it, request a tax transcript from the IRS
If you are e-filing and need verification, enter the prior-year AGI exactly as shown on your return or transcript
