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 Funds are not taxed when withdrawn for qualified medical expenses.
All funds you put in your HSA are 100% tax deductible from gross income and can be used tax-free to pay for out-of-pocket medical expenses, including dental and vision. There are limits to the amount of money you can put in tax-free and the amount of money you can use tax-free as well.
