I got married in December 2016.   I do not know How my spouse filed her taxes (we no longer speak).    I am self-employed with a 1099 and I usually expense a Lot and use deductions of all sorts....   so how do I File.?   It's my understanding that IF I select positively that I claim itemized deductions....that it might screw us both up (requiring amendments and such). 

She is a school district employee. She has 1 child from a previous marriage, she gets child support and W2   (no stocks, or dividends, or even much savings!)  hers is pretty cut & dry and filed with IRS back in February 2016.

But now... its my turn to file (after I previously applied for an extension)
