Through its unique combination of tax advantages, an HSA can save you money, both in your current and future medical costs. Spending HSA funds is like getting a discount on your health care expenses.
No "use it or lose it"
These tax advantages combined with the fact that HSAs do NOT have the same "use it or lose it" rule that Health FSAs have make it a great option for long-term savings. If you have unused funds in your HSA at the end of the year, those funds will remain in your account. This makes HSAs uniquely suited to help you pay for current medical expenses while building a nest egg to cover future health expenses. You can even take your HSA into retirement, so you don't have to dip into your 401(k) to pay for eligible medical expenses.
