Do I need to get consent from both members of a couple who is married filing jointly (MFJ)?
Couples who are married filing jointly have identical Account Transcripts, Tax Return Transcripts, and Record of Account Transcripts.
Only Wage & Income Transcripts are unique to each individual.
If one partner has no income, then you only need consent from one person to view the relevant transcripts.
For more details, read the FAQ on Types of IRS Transcripts.
