If you do not use all of the money by the end of the year that has been set aside in the HSA don't you lose it?
To the best of my memory you do not lose the money if it is not used within the year concerning the HSA. However the same can't be said for a Flex Spending account. I attended a meeting at work today & was told that a new rule would extend from December 31st to sometime in March for FSA's. However, I could be wrong because I did not GOOGLE the information.
There is much more benefits to an HSA. I have heard of people that's already near retirement & already participating in the maximum amount of money in a 401k using the HSA as another source of tax shelter because of it's 401k type structure it allows you to tap into that money at 69 or 72 or whatever without penalty. Plus some institutions even pay a very small amount of interest on HSA's. However I have never witnessed this with my own blue eyes.
