Your Prior Year Adjusted Gross Income or AGI

Prior Tax
Year AGI

Important: The information below is for entering 2017 Adjusted Gross Income (AGI) amounts on 2018 Tax Returns. However, the procedure will mostly be the same for entering 2018 AGI's on 2019 Tax Returns. We will update this page as soon as the IRS starts accepting 2019 Tax Returns in 2020. 

Your Prior-Year AGI is the Adjusted Gross Income (or AGI) on last year's tax return (2017). The IRS uses your AGI to establish your identity so you can e-File your 2018 tax return. You only need a prior-year AGI if you are e-filing your tax return to the IRS. An incorrect AGI will result in a tax return rejection by the IRS and/or State Tax Agency.

Your 2017 Tax Year Adjusted Gross Income

1) If you e-filed your 2017 tax return on follow these steps:

Sign into your account and view/download your PDF tax return file from the My Account page. The same line numbers as above apply.

2) If you filed elsewhere and you do have a copy of your 2017 1040 Tax Return Form, identify the exact form/line number for your AGI: 

  • On IRS Form 1040EZ your AGI is on Line 4
  • On IRS Form 1040A your AGI is on Line 4
  • On IRS Form 1040 your AGI is on Line 4

3) If you did NOT e-file your 2017 tax return on and you don't have a copy of your 2017 1040 click Get A Transcript Online now. This is a free service provide by the IRS. Your prior year AGI will be on the transcript. 

Keep in mind, if you filed a tax amendment for 2017 and as a result your Adjusted Gross Income changed, you need to use that new AGI amount and not the AGI amount on your originally filed 2017 tax return as stated on one of the 1040 forms listed above.

Once your return got accepted via we suggest you come back the year later to prepare and eFile your taxes and your AGI will be in your account.

How To Enter Your 2017 AGI on

Once you have your 2017 AGI sign into your tax return and follow the instructions below: 

  • Click File on the left menu.
  • You will see your refund/balance due amount. Click Continue.
  • Your return will be completed and when it is finished, click Continue. Click View Return if you want to view/print your forms. This is highly recommended so that you can see the final return that you submit to the IRS and also to make sure that you haven't entered anything incorrectly.
  • Next is the Efile Selection screen. Make sure you select the return(s) you want to efile and click Continue.
  • Select if you want to have your refund mailed or deposited and click Continue.
  • You will be asked if you (or your spouse, if your filing status is Married Filing Jointly) filed a tax return last year. Select Yes and click Continue. If you did not efile or file a tax return last year, answer No. We will automatically enter 0 as the number to verify your identity with the IRS (0 is your AGI for 2017 since you did not have any income that year or you did not file a return).
  • If you select Yes for filing a tax return last year, the next screen is To E-file, You Must Identify Yourself to the IRS. Enter your AGI in the box next to the Enter last year's AGI line. If you are filing a joint tax return, enter the same AGI for you and your spouse (if you or your spouse did not file or efile a tax return last year, enter 0 in the appropriate AGI field). Once you have entered your AGI(s), click Continue. (Note: the image below is for informational purposes only and is not interactive.) If you cannot locate your Prior Year AGI, you will need to print your return, sign it, and mail it to the IRS so it can be filed. There is no need for IRS acceptance when you mail in your return since the AGI is not needed to establish your identity.

How to enter prior-year AGI

  • Identify Protection (IP) PIN - You are asked if you (and/or your spouse) received an Identity Protection PIN from the IRS. This 6-digit PIN is assigned to a victim of identity theft and is sent to you in a letter from the IRS via certified mail. Click Yes if you received one and enter the IP PIN on the next screen, otherwise click No.
  • Personal Identification PIN - You are asked to create any 5-digit PIN to electronically sign your return. This can be any five numbers you choose except 00000 or 12345 or all the same digits such as 55555.
  • Click Continue and on the next screen, check the I'm not a robot box and click the E-file to send your return.
  • You are done! You will receive an email confirming that your return has been accepted by the IRS. You should hear back from the IRS in 24 - 48 hours concerning the status of your return. If you do not receive an email, make sure you do not have a spam filter blocking it. If your return is rejected, don't worry, you can sign into your account and see the reason why the IRS rejected it with step-by-step instructions to correct and resubmit your return.

Important: You can efile your tax return as many times as you need to at no extra charge. Simply correct your AGI and efile or re-submit your tax return again.
