Health Savings Accounts (HSAs): How They Work and How to Use Them
A Health Savings Account (HSA) is a tax-advantaged savings account available only to individuals enrolled in a qualifying High Deductible Health Plan (HDHP). Contributions are tax-deductible (or made pre-tax through payroll), account earnings grow tax-free, and withdrawals used for qualified medical expenses are also tax-free. This combination of advantages makes an HSA one of the most tax-efficient vehicles available for healthcare and retirement medical costs.
Eligibility Requirements
To contribute to an HSA, you must:
- Be covered by a qualifying HDHP
- Not be enrolled in Medicare
- Not be claimed as a dependent on someone else’s tax return
- Not have disqualifying additional coverage (such as a general-purpose Flexible Spending Account)
For 2026, the IRS minimum HDHP deductibles and maximum out-of-pocket limits are:
| Coverage | Minimum Deductible | Maximum Out-of-Pocket |
|---|---|---|
| Self-only | $1,700 | $8,500 |
| Family | $3,400 | $17,000 |
Partial-year eligibility is prorated on a monthly basis.
2026 Contribution Limits
| Coverage | Annual Limit | Catch-up (age 55+) |
|---|---|---|
| Self-only | $4,400 | +$1,000 |
| Family | $8,750 | +$1,000 |
Employer contributions count toward these limits. Excess contributions are subject to tax and should be corrected by the tax-filing deadline.
Triple Tax Advantage
- Contributions — Made pre-tax through payroll or deducted on your tax return.
- Growth — Interest, dividends, and investment gains accumulate tax-free.
- Withdrawals — Tax-free when used for qualified medical expenses.
After age 65, non-medical withdrawals are taxed as ordinary income but are no longer subject to the 20 % penalty that applies before age 65.
Qualified Medical Expenses
HSAs may be used tax-free for a wide range of expenses, including:
- HDHP deductibles, copayments, and coinsurance
- Prescription medications and many over-the-counter items
- Dental and vision care (including orthodontics and LASIK)
- Medicare Part B and Part D premiums (after age 65)
- Certain long-term care expenses and premiums
- Medical equipment and supplies
Receipts should be retained indefinitely to substantiate withdrawals. Non-qualified withdrawals before age 65 are subject to ordinary income tax plus a 20 % penalty.
HSA vs. Flexible Spending Account (FSA)
| Feature | HSA | FSA |
|---|---|---|
| Eligibility | HDHP only | Available with many plans |
| 2026 contribution limit | Higher ($4,400 / $8,750) | Lower (approximately $3,300) |
| Rollover | Unlimited | Limited or “use-it-or-lose-it” |
| Ownership | Individual (portable) | Tied to employer |
| Investment options | Broad (including brokerage) | Usually limited or none |
| Use after leaving job | Continues | Generally forfeited |
A Limited-Purpose FSA (for dental and vision only) can be paired with an HSA.
Investment and Long-Term Use
Many HSA custodians allow the account to be invested in mutual funds, ETFs, or other securities once a minimum cash balance is reached. Because qualified withdrawals remain tax-free at any age, an HSA can function as a long-term medical reserve or a supplemental retirement account. Some account holders pay current medical expenses out of pocket and allow the HSA balance to grow, reimbursing themselves years later (receipts permitting).
Employer Contributions and Practical Tips
Employer contributions are common and are excluded from taxable income. When evaluating HDHPs, compare the deductible, out-of-pocket maximum, network, and any employer HSA contribution. Maximizing the annual contribution, investing the balance when appropriate, and keeping thorough records of qualified expenses are the primary ways to capture the full value of an HSA.
An HSA offers a rare combination of upfront tax savings, tax-free growth, and tax-free spending on medical costs. It is most advantageous for individuals and families who can manage a higher deductible and who expect to use or invest the account over multiple years. Contribution limits, HDHP requirements, and qualified-expense rules are set by the IRS and should be confirmed annually.
