How to Invest Your HSA Funds for Long-Term Wealth

A Health Savings Account (HSA) is often called the 'triple tax advantage account' — contributions are pre-tax, growth is tax-free, and withdrawals for medical expenses are tax-free. But most people treat it like a checking account, spending it down every year. The smarter strategy: invest it and let it compound for decades.

The HSA Investment Strategy

The optimal HSA strategy is: contribute the maximum, pay medical expenses out-of-pocket (if you can afford to), save receipts, and invest the HSA balance in low-cost index funds. After 65, you can withdraw HSA funds for any purpose — you'll pay income tax on non-medical withdrawals, but no penalty. This makes a fully funded HSA function like a traditional IRA with a medical expense bonus.

2024 HSA Contribution Limits

• Individual coverage: $4,150/year.
• Family coverage: $8,300/year.
• Age 55+: Additional $1,000 catch-up contribution.
• You must be enrolled in a High-Deductible Health Plan (HDHP) to contribute.

How to Start Investing Your HSA

1. 1Check your HSA provider: Not all HSAs offer investment options. Fidelity, Lively, and HealthEquity have good investment choices.
2. 2Meet the minimum balance threshold: Most HSAs require $1,000–$2,000 to remain in cash before investing the rest.
3. 3Choose your investments: Low-cost index funds like total market (FSKAX, VTI) or target-date funds work well.
4. 4Automate: Set up auto-invest so contributions go directly into your chosen fund.
5. 5Save receipts: Keep records of all medical expenses. You can reimburse yourself years or decades later — there's no time limit.

The Receipt Strategy

Here's the most powerful HSA hack: pay medical expenses out of pocket today, save every receipt, and reimburse yourself from the HSA years later — while the money compounds in index funds. There's no time limit on reimbursement. A $500 dentist bill receipt from 2026 can be submitted in 2046 — and the $500 that was invested for 20 years might be worth $2,000 by then.

Best HSA Providers for Investing

• Lively: No fees, integrates with TD Ameritrade for self-directed investing.

HSA Priority in Your Financial Plan

For most people: 1) 401(k) to employer match. 2) Max HSA. 3) Max Roth IRA. 4) Max 401(k). 5) Taxable brokerage. The HSA is prioritized over the IRA because of the unique triple tax advantage — no other account offers deduction on contribution AND tax-free growth AND tax-free withdrawals.
