She owns a home and they have been living together for many years. I came to my attention after they got married that he hasn't filed taxes for over 10 years. He just this year actually got a bank account. He has done things over all the years but I guess was either paid "under the table" or bartered. He is very skilled at cars so maybe bartered with work on cars. I'm not sure.
But my niece has been paying taxes and filing her taxes. To keep her legit, I was thinking of suggesting that she files as married filing separately.
Is this a variable option and if not, what options might she have or they both have?
