What is Health Savings Account (HSA)?

An HSA is a tax-advantaged savings account available to employees enrolled in a High Deductible Health Plan (HDHP). Contributions are pre-tax, growth is tax-free, and qualified medical withdrawals are tax-free — the only "triple tax advantage" in the US tax code. For 2026, the contribution limit is $4,300 for individuals and $8,550 for families. HSA funds roll over year to year and belong to you even if you change employers.
