Tax guide

How do I find last year’s AGI?

To find your prior-year Adjusted Gross Income (AGI), look on a copy of the tax return you filed last year.

For years before 2018:

  • On a Form 1040EZ, your AGI will be on Line 4.
  • On a Form 1040A, your AGI will be on Line 21.
  • On a Form 1040, your AGI will be on Line 37.

For 2018 to the present:

  • 2018: Line 7 on Form 1040
  • 2019: Line 8b on Form 1040
  • 2020: Line 11 on Form 1040

If you filed with 1040.com, we’ll automatically carry forward your prior-year AGI to validate your identity when you file this year. You can also sign in and view a completed copy of your return from last year. In the upper left-hand corner of the PDF, you will see which main tax form your return was filed on.
