Well----whatever he did ---- if he filed a joint return that was wrong. When you file MFS you do have to put each other's SSN's on both returns----did you use his on your return? Are you sure he filed joint--- maybe he filed MFS and just entered your SSN like he was supposed to.
If I am filing a separate return why do I have to list my spouse’s information on my return?
Even if you file separate returns (the worst way to file) you each have to list each other's SSN's and some other information on your own tax return. The IRS can then cross check to make sure you are not "double dipping" for itemized deductions, dependents, etc.
If you are in a community property state, there is more information that will be needed.
Community property states: AZ, CA, ID, LA, NV, NM, TX, WA, WI
