The HSA Triple Tax Advantage
HSAs are the only account in the US tax code with three separate tax benefits. No other account — not 401(k), not Roth IRA — offers all three simultaneously.
Tax-Free Contributions
Contributions reduce your federal and state taxable income dollar-for-dollar. Payroll contributions also avoid the 7.65% FICA tax — a benefit not available with any IRA.
Tax-Free Growth
Invest your HSA balance in index funds or ETFs. All dividends, interest, and capital gains grow completely tax-free — no annual reporting required.
Tax-Free Withdrawals
Withdrawals for qualified medical expenses are 100% tax-free at any age. After age 65, you can withdraw for any reason penalty-free (ordinary income tax applies, like a 401k).

HSA as a Retirement Account — The Stealth IRA
Most people use their HSA as a spend-as-you-go medical account. But the optimal strategy is to pay medical expenses out-of-pocket while investing your HSA contributions, letting them compound tax-free for decades.
After age 65, HSA withdrawals for non-medical expenses are taxed as ordinary income — exactly like a traditional IRA. But unlike an IRA, there are no Required Minimum Distributions (RMDs) and medical withdrawals remain completely tax-free. This makes a maxed HSA functionally better than a traditional IRA for most high-earners.
Frequently Asked Questions
To contribute to an HSA you must be enrolled in a High-Deductible Health Plan (HDHP), not be enrolled in Medicare, not be claimed as a dependent, and not have other disqualifying health coverage. The 2026 HDHP minimum deductible is $1,650 (individual) or $3,300 (family). Most employer-sponsored HDHPs automatically qualify.
Qualified expenses are defined by IRS Publication 502 and include: doctor visits, prescriptions, dental, vision, mental health, physical therapy, and many more. Notably, over-the-counter medications and menstrual products became qualified in 2020. Health insurance premiums generally do not qualify unless you are on COBRA, receiving unemployment, or over 65.
Yes — most HSA providers allow you to invest once your balance exceeds a threshold (typically $500–$1,000). Fidelity HSA, Lively, and HealthEquity are popular providers with low-cost index fund options. Fidelity's HSA has no minimum and offers the same fund lineup as their brokerage — it is widely considered the best option for investors.
Your HSA balance stays yours permanently — you never lose it. You simply cannot make new contributions while enrolled in a non-HDHP plan. You can still use the existing balance for qualified medical expenses tax-free, invest it, and let it grow. If you switch back to an HDHP later, you can resume contributions.
HSAs are almost always better if you qualify. Key differences: HSA funds roll over forever (FSA is "use it or lose it"), HSAs can be invested (FSAs typically cannot), HSA contributions are yours even if you change jobs, and HSAs work after 65 as a quasi-IRA. The downside: HSAs require an HDHP, which has higher deductibles. FSAs do not have this restriction and may suit people with high expected medical costs.
