A Health Savings Account (HSA) is a tax‑advantaged savings account for individuals enrolled in a high‑deductible health plan (HDHP).
It allows you to save money pre‑tax to pay for qualified medical expenses.
The HSA is owned by the individual and may be funded by the employee, employer, or both.

To contribute to an HSA, you must:
- Be covered by a qualified HDHP
- Not have other health coverage
(except permitted coverage, such as dental or vision) - Not be enrolled in Medicare

How HSAs Affect Taxes
HSAs offer triple tax benefits:
- Contributions are tax‑deductible
(or excluded from income if made by an employer) - Earnings grow tax‑free
- Distributions for qualified medical expenses are tax‑free
HSA contributions reduce Adjusted Gross Income (AGI) and may lower overall tax liability.
Self‑employed taxpayers can deduct HSA contributions even if they don’t itemize.
Reporting Qualified Medical Expenses
- Qualified medical expenses are reported on Form 8889, attached to Form 1040
- If HSA funds are used for non‑qualified expenses, the distribution is:
- Taxable as income, and
- Subject to a 20% penalty
The 20% penalty does not apply if the account holder is:
- Age 65 or older
- Disabled
- Deceased
