A Health Savings Account (HSA) is a consumer-oriented, tax- advantaged savings account that is always combined with a Consumer Driven Health Plan (CDHP). HSA earnings grow tax-deferred and qualified withdrawals are tax-free without “use it or lose it”. Money not used in your Health Savings Account can be rolled over to the following year. HSA funds can be used for all qualified medical expenses, including medical services, as well as eyeglasses, dental procedures, prescription drug coverage and over-the-counter medications provided you submit a prescription from your provider. See IRS Publication 969 for more information and a listing of Qualified Eligible Expenses at www.irs.gov.
