Health savings account

A Health Savings Account (HSA) is a tax-advantaged savings account available to individuals enrolled in a High-Deductible Health Plan (HDHP). It allows you to contribute pre-tax dollars, grow investments tax-free, and withdraw funds tax-free for qualified medical expenses. Unlike a Flexible Spending Account (FSA), HSA funds roll over year to year and remain yours even if you change jobs or health plans, making it one of the most powerful long-term savings vehicles available under US tax law.

What Is a Health Savings Account? — 2026 Definition

A Health Savings Account (HSA) is a triple-tax-advantaged savings account established under the Medicare Prescription Drug, Improvement, and Modernization Act of 2003. In 2026, the IRS allows individuals to contribute up to $4,300 (self-only) or $8,600 (family coverage), with an additional $1,000 catch-up contribution for those aged 55 or older. Funds can be invested in options like Vanguard index funds, Fidelity mutual funds, or Lively self-directed brokerage accounts. The account is owned by the individual, not the employer, meaning it is fully portable across jobs and health plans. According to the Employee Benefit Research Institute (EBRI, 2025), approximately 36 million HSA accounts held over $130 billion in assets as of mid-2025.

How an HSA Works in 2026

An HSA functions through three distinct tax advantages that compound over time. First, contributions reduce your taxable income dollar-for-dollar in the year they are made, as reported by the IRS in Publication 969 (2025 revision). Second, any investment growth—whether in a HealthEquity self-directed account, a Fidelity HSA, or a Lively HSA—is tax-deferred. Third, withdrawals for qualified medical expenses as defined by IRS Section 213(d) are entirely tax-free. In 2026, the IRS expanded qualified expenses to include certain over-the-counter medications without a prescription, menstrual care products, and telehealth services. According to the Devenir HSA Research Report (2025), the average HSA account balance reached $5,600, with 28% of account holders investing at least a portion of their funds. The Centers for Medicare & Medicaid Services (CMS, 2026) reported that HDHP enrollment grew to 43% of employer-sponsored plans, making HSA eligibility more common than ever.

HSA vs. FSA vs. HRA vs. 401(k): Comparison Table

Account Type	Key Feature	Contribution Limit (2026)	Tax Treatment	Best For	Verto Recommendation
Health Savings Account (HSA)	Triple-tax-advantaged, fully portable	$4,300–$8,600	Pre-tax contributions, tax-free growth, tax-free withdrawals for medical expenses	Long-term medical savings, retirement healthcare costs	Strongly recommended for HDHP enrollees
Flexible Spending Account (FSA)	Use-it-or-lose-it annually	$3,200	Pre-tax contributions, tax-free withdrawals	Short-term predictable medical costs	Suitable for non-HDHP enrollees
Health Reimbursement Arrangement (HRA)	Employer-funded only	Employer-defined	Employer contributions are tax-free to employee	Employer-subsidized healthcare	Good if employer offers it, but not portable
401(k) Retirement Account	Pre-tax retirement savings	$23,000 (under 50)	Pre-tax contributions, tax-deferred growth, taxed on withdrawal	General retirement savings	Use both HSA and 401(k) if possible

Verto’s Recommendation: If you are enrolled in an HDHP, an HSA is almost always the superior choice over an FSA because of its rollover feature and investment potential. For those not in an HDHP, an FSA is the next-best option for tax-advantaged medical spending. An HRA is beneficial only if your employer funds it generously, but it lacks portability. The 401(k) serves a different purpose—retirement income—and should complement, not replace, an HSA.

Who Should Use an HSA? (and Who Shouldn’t)

If you are enrolled in an HDHP with a deductible of at least $1,600 for self-only or $3,200 for family coverage in 2026, an HSA is a strong fit. It works best for individuals who can afford to pay out-of-pocket for current medical expenses while letting HSA funds grow tax-free for future needs. If you are under 55 and in good health, the HSA functions as a stealth retirement account—you can invest contributions in low-cost index funds through providers like Fidelity or Lively and withdraw tax-free for Medicare premiums or long-term care costs after age 65.

If you are on Medicare, Medicaid, or a non-HDHP plan, you are ineligible for an HSA. If you have high ongoing medical expenses that exceed your HDHP deductible each year, an HSA may still be worthwhile for the tax deduction, but you should prioritize using funds for immediate care rather than investing. If you are in a low tax bracket and cannot afford to contribute, the immediate tax benefit is minimal—consider an FSA or employer HRA instead. Always consult a tax professional or financial advisor before committing to an HSA strategy.

Key Factors to Consider When Evaluating an HSA

Factor	What to Look For	Why It Matters
HDHP eligibility	Deductible meets IRS minimums	Without an HDHP, you cannot open an HSA
Fee structure	Monthly maintenance fees, investment fees	High fees erode long-term growth; Fidelity and Lively offer no-fee options
Investment options	Access to low-cost ETFs, mutual funds	Critical for long-term growth; Vanguard and Schwab funds are common
Contribution strategy	Max out annual limit if possible	Maximizes triple-tax advantage
Qualified expenses	Know what IRS Section 213(d) covers	Avoids penalties on non-qualified withdrawals
Portability	Account stays with you	Essential for job changers
