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 Funds are not taxed when withdrawn for qualified medical expenses.
Your HSA dollars can be used to help pay the health insurance deductible and any qualified medical expenses, including those not covered by the health insurance, like dental and vision care. Any funds you withdraw for non-qualified medical expenses will be taxed at your income tax rate, plus 10% tax penalty.
