An HSA is a special, tax-advantaged savings account you can use to pay for qualified medical expenses. You deposit money in your HSA, where it earns interest tax-free. Funds are not taxed when withdrawn for qualified medical expenses.
Once funds are deposited into the HSA, the account can be used to pay for qualified medical expenses tax-free, even if you no longer have HDHP coverage. The funds in your account roll over automatically each year and remain indefinitely until used. There is no time limit on using the funds.
