More piggy-backing..
My insurance goes from June to May. HDHP plan first became available this year, so I became eligible for HSA in June. From what I can find, in general the contribution limit is prorated, which would make my limit 1650. But, there's the Last Month exception, where if I'm HSA eligible on Dec 1, 2014 and continue to be eligible until Dec 31, 2015 (which I plan to be), I can contribute the full amount, 3300.
So am I correct in thinking my contribution limit is 3300? or is it actually 1650?
