IRS is asking for adjusted gross of spouse, but it was joint tax return

You use the same 2024 AGI on line 11 for each of you.

You need your 2024 AGI to efile 2025. The AGI is on 2024 1040 or 1040SR line 11. If you filed a Joint return you use the same AGI for each spouse.

How to find the AGI.

If you didn't file 2024 or filed it later in the year or mailed it, then try entering 0 for the AGI. If that doesn't work you will have to print and mail your return.

Or request a transcript from the IRS

On a joint tax return the AGI is the same for the both of you.

When filing a joint return, the prior agi of both spouses must be entered. AGI comes from line 11 of the return you filed for 2024.
