I finally got a difficult return to do. 1 W-2 (wife,), 9 1099-R's, 2 SSA's, plus a couple of other minor income statements. Older couple, with a $14,200 standard deduction. Their medical expenses for 2012 are over $17,000, all documented very well. The medical expenses are roughly split 52-48. Will MFS make that much difference? I have not even factored...
