Not necessarily but you need a reason for doing so. It also sounds like you need a tax professional or tax attorney because how you are handling your taxes does not sound right.

I am a tax attorney. It should always be better for you to file married jointly. If you look at the tax you pay filing separately and filing jointly, it is almost always less total tax to file jointly. Given that, why would you file separately? It seems fishy to me and I expect that it would seem fishy to the INS as well.
Please be sure and mark the best answer. Thank you! hope this helps. ***************************************** LEGAL DISCLAIMER James Oberholtzer is licensed to practice law in the Commonwealth of Virginia and the States of Illinois, Oregon and Washington.
