What happens to the money in an HSA after I turn age 65?

You can continue to use your account tax-free for out-of-pocket health expenses. When you enroll in Medicare, you can use your account to pay Medicare premiums, deductibles, co-pays and coinsurance under any part of Medicare. If you have retiree health benefits through your former employer you can also use your account to pay for your share of retiree medical insurance premiums; however, the coverage may not be a Medicare Supplement Policy. Medicare premiums for a dependent who has reached age 65 is not an eligible expense.
