<prompt> Human: I got married two years ago. Since weve been married we have been married filing separate because we didnt quite understand filing jointly. However, In trying to fill out my FAFSA, it seems like the way we filled out our taxes may not line up.Plus, I remember being told that getting married got you more money on your taxes, it sure doesnt feel like it!  <response>: MFJ will almost surely get you lower taxes, so its probably worth calculating one years numbers. You can then figure out if you made a good enough hourly rate to justify amending the other years.
