I am trying to figure out how to file my taxes for 2011.

My wife was a W2 for part of the year and created and LLC the second half, when she started doing contract work.

I earned $140k in 2011 with $120k of it being taxable income (minus 401k and FSA). My wife earned about $25k as a W2 employee and $22k when she started her LLC. I am wondering if we should file jointly, or separately. Thanks for the help.
