There are several ways.
He can prepare a joint return and ask you to sign it. It is up to you if you want to cooperate. This assumes that you are still legally married.
He can forge your signature on a joint return. This would be illegal.
He can impersonate you and e-file a return. This would be fairly easy for a spouse to do, but it is also illegal.
If you had absolutely no income during the year, did not file a return of your own, and could not be claimed as a dependent on anyone's return, the law allows your husband to claim your personal exemption on his separate tax return. Note this is not the same as claiming you as a dependent. (Your spouse is never your dependent for federal tax purposes.)
You need to file a Injured spouse form. This would be done by the party who belives they are not liable.
Yes, a husband and wife can choose to file their income taxes separately if they meet certain criteria.
“husband and wife live together but file separately. both are itemizing deductions. husband pays mortgage and r/e taxes. house in both names. does the mortgage interest and r/e taxes have to be split if all paid by husband or is husband entitled to take full deduction.”
Yes, this is done with a lot of couples these days.
File injured spouse forms to separate your tax liability from his.
Yes, but you can file a form to get your part. See links
They both must file for a divorce, from the city they are both staying in .
For 2010 I was separated from my wife. For the 2010 year she was on SSI. How should I file my taxes? I had to pay her doctor bills and other maintenance expences also. Can I file "head of household" with her as a dependent? or, should I file single?
No. Get a restraining order and file charges for trespassing.
Married but filing separate
If they are legally separated on the last day of the tax year, then yes. Otherwise, no.
I am not a lawyer but before we got married, my husband and I, filed taxes together as a living together couple.
