Thanks dandarc. The HSA is an interesting option. I switched jobs in October, and my new job does NOT have an HDHP that would make me eligible for an HSA, but my previous job did.
I know the contribution limit can be pro-rated, for example, if I didn't have an HDHP-eligible plan until July last year, then I could contribute up to half of the contribution limit.
I'm assuming that doesn't work the other way around. Since I had an HDHP and my employer contributed to my HSA January - September of last year, I'm guessing I can't now, retroactively, contribute up to 3/4 of the HSA limit to lower my MAGI.
Anyone know if I'm correct in thinking that I can't do this, or this a sort of loop-hole?
