Your AGI is your adjusted gross income, and you’ll need your prior-year AGI to validate your electronically filed (e-filed) tax return.

The questions and answers below will help you find your AGI.

Do you have your 2016 tax return?

If yes, find your AGI here:

  • Line 37 of Form 1040
  • Line 21 of Form 1040A
  • Line 4 of Form 1040EZ

Did you pay someone to prepare your tax return last year?

  • If yes, ask him or her for a copy of last year’s tax return.

Are you a new or returning TaxSlayer?

  • If you’re a new TaxSlayer, just take a look at your prior-year tax return for the info you need.
  • If you’ve slayed your taxes with us before, we’ll automatically pull the data from your prior-year tax return.

Do you have an Identity Protection (IP) PIN (via a CP01A)?

  • If yes, you can use it to verify who you are, but you’ll still need to enter your AGI.

Are you over age 16 and filing for the first time?

  • Enter zero as your AGI.

Are you under age 16 and filing for the first time?

  • You must print, sign, and mail your tax return to the IRS. Mail paper returns here.

Do you need a tax return transcript, which shows your AGI?

 You have two options:

  1. Getting your transcript online gives you instant access to your AGI.
  2. Getting your transcript by mail takes 5 to 10 days for delivery.
