What are the benefits of an HSA?

HSAs are benefit heavy.

1- They are triple tax-free (money input into the account is tax free. Interest gained on the account is tax free. If used on medical expenses, those are tax free as well.)

2- They can be rolled over year to year gaining interest.

3- They have pretty high limits on the amount you can put in them. ($3450 for indiuvudual and $6900 for families)
