How do I find last year’s AGI?

Updated for filing 2021 tax returns

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

Your 2020 AGI will be on Line 11 of 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.

Still waiting on your 2020 tax return to be processed? Or simply didn't file last year? Here's what to put for prior-year AGI.

The location of AGI is different depending on the year. For years before 2018, the location of your AGI depends on the form you filed:

Form 1040EZ: Line 4
Form 1040A: Line 21
Form 1040: Line 37

For 2018 to the present, your AGI is located as follows:

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