Health Savings Account
HSAs allow employees in High-Deductible Health Plans to establish pre-tax savings accounts to be used for qualified medical expenses, such as co-pays, prescriptions, and more.
Earnings on your account may be used to pay qualified medical expenses without incurring any tax liability. And unlike with Flexible Spending Accounts, the money placed into an HSA does not need to be spent in the year you deposit it. In fact, you can keep it in the account indefinitely for use at any later date.
Plus, the money belongs to you. If you change jobs or move, your funds stay in the account and are yours to use on qualified medical expenses.
