A Health Savings Account (HSA) is a tax-advantaged savings account available to individuals enrolled in an HSA-qualified high-deductible health plan (HDHP). HSAs offer a triple tax advantage: contributions are tax-deductible, investment growth is tax-free, and withdrawals for qualified medical expenses are also tax-free.
Unlike flexible spending accounts (FSAs), HSA funds roll over from year to year with no use-it-or-lose-it requirement, and the account is fully portable — it belongs to the individual, not the employer. More than one-third of Americans with private health insurance are now covered by an HSA-eligible plan, making HSA knowledge essential for any tax or financial planning professional.
