Remember, this thread is how to take advantage under "Obamacare". Under the ACA HSAs won't be nearly as attractive:
1) The cost-sharing of the various metal tiers will limit the number of HDHP plans available;
2) HSAs will be watered down from their prior incarnations; and
3) HDHP premiums won't be the good "deal" they are now compared to standard plans.
Individual premiums will likely go up 50% or more for those at 250% FPL and above (depending on your state) so people just won't have the cash to dump into the HSA. Making things worse, the more disposable income you have the more your premium will go up since you won't even get the benefit of the paltry 8.5% OOP Max advance premium tax credit. There's actually a really good study out there, I thought it was one Wakely did for Oregon but I just checked and it's not, if I find it I'll link it.
Edit: Well poop. The report was the Wakely report for Oregon, but the specific chart I was thinking of was in the report Gorman did for us.
