How do I find last year's AGI?

Explains how to find your prior-year AGI for e-filing, including where to locate it on Form 1040, what to enter if you didn’t file last year, and how to resolve AGI mismatch rejections.

You can find last year's AGI on Line 11 of your prior-year IRS Form 1040 (your 2025 return). If you didn't file a tax return last year, enter $0 as your AGI.

Your adjusted gross income (AGI) is your total income after certain adjustments. The IRS may use your prior-year AGI to verify your identity when you e-file your tax return.
​

Important: Enter your AGI exactly as it appears on your prior-year return. If it doesn't match IRS records, your return may be rejected and you'll need to correct it before resubmitting.

The fastest ways to find your AGI

1. Check last year’s tax return

If you have a copy of your return, look at Line 11 on your 2025 IRS Form 1040. That number is your AGI.
​
​Note: If you amended your 2025 return, use the AGI from your original return, not the amended version.
​


2. View your return if you filed taxes with april last year

If you used april to file last year, you can download your return directly from your account:

  1. Sign in to your april account

  2. Open Document Manager (look for the folder icon)

  3. Find Previous tax years and select 2025 return next to it

  4. Open your Form 1040 and find your AGI on Line 11

3. Download your return from another tax software

If you filed with another tax software (like TurboTax, TaxAct, H&R Block, or a similar product), sign in to your account and download your 2025 IRS Form 1040. Your AGI will be on Line 11 of the first page.

4. Find your AGI through the IRS

If you can't access a copy of your return, you can find your AGI in your IRS online account.

  1. Sign in or create an IRS online account

  2. Go to Records and Status

  3. Select tax year 2025

  4. Find your adjusted gross income (AGI)

If you can't access your online account, you can request a tax return transcript from the IRS.

What if I didn't file taxes last year?

  • If you didn't file a federal return last year, enter $0 as your AGI.

  • If your prior-year return wasn't processed in time, you may need to enter $0. This also applies if your return was rejected and you never successfully refiled it.

  • If someone else claimed you as a dependent last year, your AGI depends on whether you filed your own return. If you didn't file, enter $0. If you did, use the AGI from Line 11 of your 2025 Form 1040.

If you still can’t e‑file

If your return was rejected because your AGI doesn't match IRS records:

  1. Check the AGI you entered against Line 11 of your original 2025 Form 1040

  2. Correct the amount and resubmit your return

  3. If you didn't file last year, make sure you entered $0

If your AGI still doesn't match, you can contact april Customer Support or the IRS for help.

You can also print and mail your return, since mailed returns don't require prior-year AGI verification.
