Most people think of a Health Savings Account () as a way to pay for medical expenses. But savvy investors know it is actually one of the best investment accounts in existence—better than a or in many ways.
The Triple Tax Advantage
An HSA offers three tax benefits that no other account can match:
- Tax- contributions — Reduces your taxable income (like a 401(k))
- Tax-free growth — No taxes on investment gains (like a )
- Tax-free withdrawals — No taxes when used for medical expenses
Pro Tip
This is the only account type that gives you a tax break going in, while invested, AND coming out. Nothing else comes close.
How HSAs Work
Eligibility
You can contribute to an HSA if you:
- Have a High Deductible Health Plan (HDHP)
- Are not enrolled in Medicare
- Are not claimed as a dependent
- Have no other non-HDHP health coverage
2024 Contribution Limits
| Coverage Type | Under 55 | 55 and Older |
|---|---|---|
| Individual | $4,150 | $5,150 |
| Family | $8,300 | $9,300 |
What Counts as an HDHP (2024)
- Minimum deductible: $1,600 (individual) / $3,200 (family)
- Maximum out-of-pocket: $8,050 (individual) / $16,100 (family)
The Secret: Invest Your HSA
Most people use their HSA like a checking account—money goes in, money comes out for medical bills. But here is the strategy that builds serious wealth:
Pay medical expenses out of pocket now. Invest your HSA for decades. Reimburse yourself later.
Consider this: You have a $500 medical bill today. You could pay it from your HSA, or you could pay cash and leave that $500 invested.
At 7% annual returns, that $500 becomes $3,870 in 30 years. And you can STILL withdraw it tax-free for that original $500 medical expense—you just need to keep the receipt.
The Stealth Retirement Account
After age 65, an HSA becomes even more flexible:
- Withdrawals for ANY purpose are allowed
- Medical withdrawals remain tax-free
- Non-medical withdrawals are taxed as ordinary income (like a 401(k))
This makes the HSA a backup retirement account. Use it for medical expenses tax-free, or treat it like a if you do not need it for healthcare.
HSA Investment Strategy
Step 1: Find an HSA with Good Investments
Not all HSAs are created equal. Look for:
- Low-cost as investment options
- Low or no account fees
- No minimum balance to invest
Good HSA providers for investing:
- Fidelity (no fees, great funds)
- Lively (partners with Schwab)
- HSA Bank (TD Ameritrade integration)
Do This
If your employer's HSA has high fees or poor investment options, you can transfer to a better provider once per year. The tax benefits are worth the effort.
Step 2: Keep a Cash Buffer
Maintain enough cash in your HSA to cover your deductible. Invest the rest.
Step 3: Max It Out
Contribute the maximum every year if possible. This is often more valuable than contributing beyond your match.
Prioritizing Your HSA
Where does the HSA fit in your savings priority?
- up to employer match (free money)
- Max out HSA (triple tax advantage)
- Max out Roth IRA
- More 401(k) or taxable brokerage
Pro Tip
The HSA often beats even the Roth IRA because of that upfront . If you are in the 22% , a $4,150 HSA contribution saves you $913 in taxes immediately.
Tracking Medical Expenses
To reimburse yourself years later, you need proof:
- Save all medical receipts — Digital copies work fine
- Keep a simple spreadsheet — Date, amount, what it was for
- Do not lose this documentation — You may need it decades later
The IRS has no time limit on reimbursement. A medical expense from 2024 can be reimbursed in 2054 if you kept the receipt.
Common HSA Mistakes
Avoid This
Do not treat your HSA as only a spending account. The real power comes from investing and letting it grow for decades.
Other mistakes:
- Not investing the balance
- Using high-fee HSA providers
- Not maximizing contributions
- Losing track of receipts for future reimbursement
- Forgetting the catch-up contribution at 55
HSA vs. FSA
Do not confuse HSAs with Flexible Spending Accounts (FSAs):
| Feature | HSA | FSA |
|---|---|---|
| Rollover | Yes, forever | Use it or lose it |
| Portability | Stays with you | Employer-owned |
| Investment | Yes | No |
| Contribution limit | Higher | Lower ($3,200) |
HSAs are far superior for long-term wealth building.
The Bottom Line
Quick Win
If you have an HDHP, open an HSA immediately and start maxing it out. If your current HSA has poor investment options, transfer to Fidelity or another low-cost provider. This single account can be worth hundreds of thousands of dollars by retirement.
The HSA is a hidden gem that most first-generation wealth builders overlook. Do not make that mistake.
