Health Savings Accounts ( HSA's )
An IRA-like account used to pay non-covered medical expenses. Used in conjunction with a high deductible health insurance plan. Unused amounts and earnings roll over forever, are the property of the account holder, and can be used for almost any uncovered medical expense (other than payment of medical insurance premiums).
