A Health savings account is simply a checking account that allows you to pay for qualified medical expenses on tax advantaged basis. The account may be established at any bank that provides these types of services. In order to reap the advantages of an H.S.A. you must be insured by a High deductible Health Plan (HDHP) as specified by the IRS.
H.D.H.P.s are available to both groups and individuals and they are simply an insurance plan with a high deductible threshold. The concept is that the premium savings, if deposited into the H.S.A. will provide more control to the insured and encourage wise use of the funds. If they are not “spent” on qualified medical expenses, they may be rolled over from year to year. There are no limits on the amount of funds that can be in an H.S.A. but there are limits on annual contributions. This graphic will give an overview of how insurance and an H.S.A. work.
