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.
✅ Eligibility Requirements
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
- ❌ Not be claimed as a dependent on someone else’s tax return
📊 2025 Contribution Limits
- Self‑only coverage: Up to $4,300
- Family coverage: Up to $8,550
- Catch‑up contribution (age 55+): Additional $1,000
✅ These limits include both employer and employee contributions.
⚠️ Contributions over the limit may be subject to a 6% excise tax unless corrected by the tax filing deadline.
👨👩👧👦 Self‑Only vs. Family Coverage
- Self‑only coverage
HDHP covers only the account holder - Family coverage
HDHP covers the account holder and at least one other person

(or excluded from income if made by an employer) - Earnings grow tax‑free
