Quick Answer
HSAs let a High-Deductible Health Plan enrollee set aside money that is deductible going in, grows tax-free, and comes out tax-free for qualified medical expenses; the exam calls this the "triple tax advantage." The account is portable, rolls over with no use-it-or-lose-it deadline, and after age 65 non-medical withdrawals lose their 20% penalty and are taxed like a Traditional IRA.
Health Savings Accounts (HSAs) are tax-advantaged accounts for paying qualified medical expenses. Often called the account with a "triple tax advantage".
Who Is Eligible to Contribute?
Must be enrolled in a High-Deductible Health Plan (HDHP) to contribute. Cannot contribute once enrolled in Medicare.
2026 HDHP definition:
| Coverage Type | Minimum Deductible | Maximum Out-of-Pocket |
|---|---|---|
| Self-only | $1,700 | $8,500 |
| Family | $3,400 | $17,000 |
What Are the Contribution Limits?
| Year | Self-Only | Family |
|---|---|---|
| 2025 | $4,300 | $8,550 |
| 2026 | $4,400 | $8,750 |
| Catch-up (age 55+) | Additional $1,000 | Additional $1,000 |
What Is the Triple Tax Advantage?
The "triple tax advantage" is the exam's defining phrase for HSAs:
- Contributions are pre-tax (payroll) or above-the-line deductible (if made directly)
- Earnings grow tax-free
- Qualified distributions are tax-free
Think of it this way: Money goes in tax-free, grows tax-free, and comes out tax-free (for medical expenses). No other account type offers all three benefits at once.
What Medical Expenses Qualify?
- Deductibles, co-pays, and prescriptions
- Dental care and vision care
- Certain over-the-counter items
Insurance premiums: as a general rule, HSA funds cannot pay health insurance premiums. Five exceptions are qualified:
- COBRA continuation coverage premiums
- Health coverage premiums while receiving unemployment compensation
- Medicare premiums (Part A, B, or D) once the account holder is age 65 or older (Medigap/Medicare supplement premiums do not qualify)
- Long-term care insurance premiums, subject to IRS age-based dollar limits (not the full premium)
- Direct primary care service arrangements
Exam Tip: Gotchas
- Deductibles and co-pays are not premiums. They are always qualified. Premiums are excluded by default; only the five exceptions above are qualified.
What Happens to Non-Qualified Withdrawals?
- Before age 65: Ordinary income tax + 20% penalty
- After age 65: Ordinary income tax only, no penalty. Effectively functions like a Traditional IRA for non-medical expenses.
Exam Tip: Gotchas
- After age 65, non-medical HSA withdrawals = taxable income only, no penalty. Same tax treatment as a Traditional IRA.
Is an HSA Portable?
- Account is portable: belongs to the individual, not the employer; stays with the account holder if they change jobs
- HSA funds roll over indefinitely; no "use it or lose it" rule (unlike Flexible Spending Accounts)
- Can invest HSA funds in stocks, bonds, and mutual funds (similar to a retirement account)
- Cannot contribute to an HSA once enrolled in Medicare
How Does an HSA Compare to an FSA?
| Feature | HSA | FSA (Flexible Spending Account) |
|---|---|---|
| Rollover | Unlimited rollover | Generally "use it or lose it" (employer may allow a limited carryover, indexed annually) |
| Portability | Yes: belongs to individual | No: tied to employer |
| HDHP required | Yes | No |
| Investment options | Yes (stocks, bonds, funds) | No |
| Contribution source | Employee and/or employer | Employee (employer may contribute) |
Exam Tip: Gotchas
- HSA triple tax = pre-tax contributions + tax-free growth + tax-free medical withdrawals. No other account type offers all three benefits simultaneously.
- FSA is tied to the employer. HSA is portable and belongs to the individual.
What Should You Check on Exam Day?
- HSA eligibility requires HDHP enrollment; contributions stop once the account holder enrolls in Medicare.
- The triple tax advantage is unique to HSAs: pre-tax or above-the-line-deductible contributions, tax-free growth, and tax-free qualified withdrawals.
- Deductibles and co-pays are always qualified expenses; insurance premiums are excluded by default except for the five listed exceptions (COBRA, unemployment-period coverage, Medicare Part A/B/D at 65+, limited long-term care premiums, and direct primary care service arrangements).
- Non-qualified withdrawals before 65 cost ordinary income tax plus a 20% penalty; after 65 the penalty disappears and the account is taxed like a Traditional IRA.
- HSA funds roll over indefinitely and stay with the individual across job changes; an FSA is generally use-it-or-lose-it and tied to the employer.
