Keeps rejecting my 2025 return due to incorrect AGI but it is not incorrect. Could this be happening because I'm using another email address?

your e-mail address is not used for verification purposes by the IRS.  It only matches your prior year's adjusted gross income and SSN as provided on your 2025 filing to those on your 2024 return.  if you filed late (after 10/15/2025) try zero for prior-year AGI.

if timely, round AGI to a whole number. 50 cents or more is rounded up to the next whole dollar, 49 cents or less is dropped (The IRS does allow rounding of all $ amounts entered into your return following the above rule. thus AGI will be a whole number) 

If you filed 2024 on time, the IRS wants the AGI from the original return, not any amended filings. 

Sometimes, for reasons unknown, nothing works. In that case you'll have to mail your return folloowing the filing instructions provided. Use a tracking method so you'll know that the IRS got it, but it may not be processed that day. It will sit in a mailbag until the IRS gets to it and if you check before it is processed, the iRS will say they never got it. .

@ lightning1031   

Is this a single return as opposed to married filing joint?   If it's a joint return, report back with the rejection error code/message so we can know whose 2024 AGI is failing.

Don't give up without resubmitting by using a 2024 AGI of 0 as @Mike9241  suggested above.

If the AGI of 0 were to also fail, then there is one last thing to try, but it's a bit onerous unless you already have an IRS online account.   One could get an IP PIN which is a more powerful verifier than the AGI; i.e., it supersedes.  The IRS says an IP PIN can be used to verify your return instead of the prior-year AGI.   The IP PIN is entered in a special interview topic.   We can tell you more about that, if necessary, but first see if an AGI of 0 works.
