An HSA (Health Savings Account) is a tax-free savings account for healthcare expenses. Contributions are tax-free, the money grows tax-free, and withdrawals for qualified expenses are tax-free. HSAs don’t have a “use-it-or-lose-it” rule, are portable (you can take them with you if you change jobs), and allow flexible contribution amounts throughout the year. Additionally, once the balance grows, you can invest it in the stock market. HSAs can be used for many health-related items, and they’re a smart way to save for future healthcare costs.
