Health Savings Accounts (HSAs) have become a popular way to pay for out-of-pocket medical expenses and/or save for future medical expenses. HSAs are considered by many to be the “unicorn” of financial accounts. The primary reason for this claim to fame are the triple tax advantage features of HSAs. Contributions are taxdeductible, earnings and interest grow tax-deferred, and withdrawals are tax-free provided the money is used for an out-of-pocket medical expense.
