The Health Savings Account (HSA) is the most tax-advantaged account in the entire code, and most Houston households who qualify dramatically underuse it. Triple tax benefit: contributions are deductible, growth is tax-free, withdrawals for medical are tax-free. No other account does all three. Here’s how to use it.
Who qualifies
You need a high-deductible health plan (HDHP) — minimum deductible $1,700 self-only / $3,400 family in 2026. Many employer plans qualify. So do most ACA marketplace bronze and silver plans. If your plan is HSA-eligible, the insurer or your HR will tell you.
2026 contribution limits
- Self-only HDHP: $4,400
- Family HDHP: $8,750
- Catch-up (age 55+): additional $1,000
Both spouses can contribute the full family amount if each has their own HSA, but the combined household limit is the family cap.
The triple tax benefit
1. Deductible going in. Contribution reduces your taxable income. At 32% federal + 0% Texas + 1.45% Medicare = ~33.5% savings.
2. Growth is tax-free. Unlike a 401(k) or IRA, you don’t pay tax on dividends, interest, or capital gains inside the HSA.
3. Withdrawals are tax-free for qualified medical expenses. Forever. No required minimum distributions, no time limit.
Stack all three and a $4,300 contribution that grows for 25 years and is used for medical expenses produces 100% tax-free wealth. No other account does this.
The investing strategy that maximizes the HSA
Most people use HSA as a checking account — pay medical bills, get reimbursed. That’s leaving 80% of the value on the table. The optimal strategy:
- Pay medical bills out of pocket from your regular accounts
- Save every receipt
- Invest the HSA in low-cost index funds (Fidelity HSA, HealthEquity, Lively all offer this)
- Let it grow tax-free for decades
- Reimburse yourself for old medical expenses anytime — the IRS doesn’t care if it’s 30 years later, as long as you have receipts
This converts the HSA from a flow-through account into a long-term tax-free investment vehicle.
HSA vs Roth IRA priority
For households eligible for both, fund HSA first. Better tax treatment than even a Roth (which is post-tax going in; HSA is pre-tax going in AND tax-free coming out for medical).
After age 65
HSA withdrawals for non-medical expenses become tax as ordinary income (no penalty). It functions like a traditional IRA at that point. Plus all qualified medical expenses (including Medicare premiums!) remain tax-free withdrawal categories. Best of both worlds.
Common Houston mistakes
- Not maxing the contribution because of cash flow concerns — the tax savings are too good to skip
- Using the HSA as a checking account for current medical bills
- Holding HSA in cash earning 0.1% — invest it
- Forgetting to track receipts for future tax-free reimbursement
- Both spouses contributing to one HSA when each could have their own
If you’re self-employed
You can buy an HDHP through the marketplace and contribute to your own HSA. Self-employed people often have the most flexibility to choose an HSA-eligible plan and capture the full benefit. Pair with a high-income year and the deduction is meaningful.
Bottom line
If your household is on an HDHP, max the HSA contribution every year. Invest it. Pay medical bills out of pocket. The compounding tax-free growth is the highest-quality dollar you can put in any retirement account.
