Something to keep in mind is that the columns don't line up properly, so be careful what columns you fill out!
Now I am fine with doing my own taxes - and indeed have set up my own spreadsheet to make doing my taxes about as pain-free as possible (i.e., proactively attacking the problem) - but I can only imagine how frightening that form must be for most folks getting the PTC (they are all lower-income after all). It is so much better to have the ObamaRomneyHeritageCare Medicaid expansion - and being eligible for AARP, I don't have to worry about my governor mandating work requirements to keep it (something I am very disappointed in my Democratic Governor John Bel Edwards for thinking about, although he might be doing some counterespionage on this, so I'll have to wait to pass judgment on).
