I'm still trying to get my head around whether I can deduct traditional IRA contributions as part of my modified adjusted gross income (the magic number for the Obamacare tax credit). I believe I've read threads here that says the deduction is applicable to MAGI, but this IRS document
seems to say no. The document's publication date is 2004, though -- a search of the IRS site doesn't come up with anything newer. Was something in the MAGI definition changed since then?
I suppose a call to IRS would provide a definitive answer, but then again, maybe not.
