If we ever needed the money for medical expenses, it would still be there. But if not, it would grow tax-free to a potentially much larger amount. When we were ready, we would pull out our receipts and reimburse ourselves tax-free from our HSA, leaving any balance for future use. Should we be fortunate enough to remain healthy, after age 65 we would be able to take it out to spend as we please, just as with our IRA and 401(k) accounts, paying only the taxes then due.
