Would couples who filed married filing jointly have the same tax transcript?

Yes, your tax return transcript would be the same. However, your wage & income transcript (shows all 1099s, W-2s, etc.) is reported under your individual social security numbers.

Ok, thank you. My 2018 return was rejected because my spouse's 2017 AGI didn't match IRS records. If we filed married filing jointly and our AGI is the same, how could mine match and not hers? Just trying to figure out if it was worth requesting transcript.
