The Triple Tax Advantage of the Health Savings Account
An HSA is widely considered the most tax-advantaged account in the US tax code because it offers a triple tax break: 1) Contributions are 100% tax-deductible (and exempt from FICA when made via payroll); 2) Investment earnings grow completely tax-free; and 3) Withdrawals for qualified medical expenses are 100% tax-free at any age.
Unlike an FSA, HSA funds never expire—they remain yours forever, rollover year to year, and can be invested in mutual funds and ETFs for decades.
