Health Savings Accounts Underutilized as Long-Term Retirement Vehicles, New Research Reveals

A significant majority of Health Savings Account (HSA) holders are primarily using these powerful financial tools for immediate medical expenses rather than leveraging their full potential as long-term investment vehicles for retirement healthcare costs, according to recent findings from the Employee Benefit Research Institute (EBRI). This trend suggests that while HSAs are widely adopted, a crucial aspect of their design – the "triple tax advantage" and capacity for tax-free growth – remains largely untapped by many account holders, potentially leaving individuals underprepared for substantial healthcare expenditures in their later years.

The EBRI study, which surveyed a broad spectrum of HSA participants, found that nearly two-thirds of individuals with these accounts prioritize using them for current or near-term healthcare needs. This approach, while addressing immediate financial burdens, often overlooks the substantial benefits of allowing HSA funds to grow untouched over decades, benefiting from compound interest and tax-free investment returns. For those who possess the financial flexibility to cover present medical bills from other sources, this immediate utilization represents a missed opportunity to build a robust, tax-advantaged fund specifically earmarked for the often-prohibitive costs of healthcare in retirement.

Understanding the Health Savings Account Landscape

Health Savings Accounts were established as part of the Medicare Modernization Act of 2003, designed to encourage individuals to take a more active role in managing their healthcare costs while providing a tax-advantaged savings mechanism. To be eligible for an HSA, an individual must be enrolled in a high-deductible health plan (HDHP) and not have other disqualifying health coverage, such as Medicare or Medicaid, nor be claimed as a dependent on someone else’s tax return. These accounts are unique in the American tax code, offering a distinct "triple tax advantage":

1. Tax-Deductible Contributions: Funds contributed to an HSA are made with pre-tax dollars, reducing an individual’s taxable income for the year. This applies whether contributions are made through payroll deductions or directly by the individual.
2. Tax-Free Growth: Any investments held within an HSA, such as mutual funds, stocks, or bonds, grow tax-free. This means dividends, interest, and capital gains are not subject to annual taxation, allowing the balance to compound more rapidly.
3. Tax-Free Withdrawals: Qualified medical expenses, ranging from doctor visits and prescription drugs to dental care and vision services, can be paid for with tax-free withdrawals at any age. After age 65, funds can be withdrawn for any purpose without penalty, though non-medical withdrawals will be subject to ordinary income tax, similar to a traditional 401(k) or IRA.

This combination of tax benefits, particularly the tax-free growth and withdrawals for medical expenses, positions HSAs as arguably one of the most powerful savings tools available for future healthcare needs. Unlike Flexible Spending Accounts (FSAs), HSA funds roll over year after year and are portable, meaning they belong to the individual even if they change employers or health plans.

The Prevalence of Short-Term Thinking

Despite these compelling advantages for long-term savings, the EBRI survey highlights a prevailing focus on immediate utility. More than half of respondents (54%) indicated that their primary motivation for opening an HSA was their employer’s contribution to the account. This suggests that for many, the HSA is viewed more as a supplemental benefit or an extension of their health insurance, rather than a strategic financial planning instrument. The survey also noted a curious trend: fewer respondents cited the tax advantages as a reason for opening an HSA in the current year compared to 2024, even as overall account balances have continued to grow across the industry. This could indicate a lack of awareness regarding the full scope of HSA benefits or a shift in immediate financial priorities.

This inclination towards short-term use is further exacerbated by the practical design of many HSA platforms. As Geoff Schmidt, a certified public accountant and founder of Holy Schmidt, a retirement education hub, aptly observes, "People think an HSA is a spending account. The name says savings, but the plumbing says checking. You receive a debit card, and consumer behavior follows the debit card." The immediate accessibility of funds via a debit card encourages a transactional mindset, where the HSA functions much like a checking account for everyday medical expenditures. Given the escalating costs of healthcare in the United States, it is entirely understandable why many families find themselves needing to access these funds to cover current out-of-pocket expenses.

The Unaddressed Retirement Healthcare Burden

The implications of this short-term focus are significant when considering the substantial financial burden of healthcare in retirement. Fidelity Investments, in its 25th annual retiree healthcare cost estimate, projected that a 65-year-old retiring this year could anticipate spending an average of $185,500 on healthcare and medical expenses throughout their retirement years. This figure, which excludes potential costs for long-term care, underscores a critical gap in many individuals’ retirement planning. Without a dedicated, tax-advantaged savings vehicle like an HSA fully leveraged for long-term growth, retirees may find themselves drawing from other taxable retirement accounts (like 401(k)s or IRAs) to cover medical bills, thereby diminishing their overall financial security.

Healthcare costs typically escalate with age due to an increased likelihood of chronic conditions, greater need for specialized medical care, and prescription medications. Medicare, while providing essential coverage, does not cover all expenses, leaving retirees responsible for deductibles, co-pays, premiums for supplemental plans, and services not covered by the program (e.g., most dental, vision, and hearing aids). An HSA, if allowed to accumulate and grow through investment, could provide a vital buffer against these unpredictable and often high costs.

The Investment Gap: A Missed Opportunity for Growth

A critical finding that underscores the underutilization of HSAs for long-term savings is the low rate of investment within these accounts. Data from Devenir, an HSA investment firm, indicates that only about 10% of HSA accounts were actually invested at the end of 2025, though this figure represents an increase from 7% in 2023. While these invested accounts held nearly half of all HSA assets, suggesting that individuals with larger balances are more likely to invest, the vast majority of HSA holders are leaving their funds in cash, earning minimal interest.

This reluctance to invest HSA balances represents a significant missed opportunity. Many HSA providers offer a range of investment options, including mutual funds and exchange-traded funds (ETFs), allowing account holders to potentially achieve much higher returns than those offered by standard cash accounts. Over a span of several decades, the power of compound interest, combined with the HSA’s tax-free growth, can transform even modest contributions into substantial sums. For example, a consistent annual contribution of $3,000 invested at an average annual return of 7% would grow to over $300,000 in 30 years, all tax-free for qualified medical expenses. If left in cash, that same amount would barely keep pace with inflation.

Strategies for Maximizing HSA Potential

Financial advisors and retirement planners increasingly advocate for strategies that prioritize the long-term growth of HSAs, particularly for individuals with stable finances.

1. Pay Out-of-Pocket and Reimburse Later: One highly effective strategy involves paying current medical expenses out of pocket, if financially feasible, and meticulously saving all receipts. By doing so, the HSA funds can remain invested and continue to grow tax-free. Years or even decades later, individuals can reimburse themselves tax-free for those past qualified medical expenses, effectively withdrawing a much larger sum than originally spent, all without incurring taxes. This strategy requires exceptional "documentation discipline," as Schmidt cautions, noting, "If you can’t produce the receipt in 2046, the strategy was theoretical." Digital record-keeping can significantly mitigate this challenge.

2. Prioritize Investing: For those who can maintain a comfortable emergency fund outside their HSA, prioritizing investment within the HSA is crucial. Most providers require a minimum cash balance before allowing investments, typically ranging from a few hundred to a few thousand dollars. Once this threshold is met, actively allocating funds to suitable investment options can dramatically accelerate growth.

3. Integrate into Overall Retirement Planning: Financial professionals emphasize integrating the HSA into a holistic retirement plan. This involves assessing an individual’s cash flow, other retirement savings vehicles (401(k)s, IRAs), and projected healthcare needs. For younger workers with decades until retirement, maximizing HSA investments can be a game-changer. For those closer to retirement, the strategy might shift to a more conservative investment approach while still leveraging the tax benefits.

Balancing Immediate Needs with Long-Term Goals

It is crucial to acknowledge that the long-term investment approach is not universally appropriate. For many individuals and families, the immediate financial relief provided by using HSA funds for current medical bills is a necessity, not a choice. As Schmidt wisely points out, "If paying a $4,000 medical bill out of pocket means carrying it on a card at 22%, you’ve just lost money protecting an account growing at 7%. The math doesn’t work no matter how good the tax treatment is." In such scenarios, using the HSA to prevent high-interest debt or deplete emergency savings is undoubtedly the better financial decision.

The optimal HSA strategy is highly individualized, depending on one’s current financial situation, income stability, existing savings, and proximity to retirement. A worker in their 20s or 30s has a much longer runway to benefit from aggressive investment growth compared to someone approaching Medicare eligibility. Financial literacy and access to sound financial advice play a pivotal role in helping individuals navigate these choices.

Broader Implications and Future Outlook

The EBRI research highlights a significant educational gap regarding the full capabilities of HSAs. If more individuals understood and utilized these accounts as long-term investment vehicles, it could have a profound positive impact on retirement security across the nation. A population better prepared for healthcare costs in retirement would potentially reduce the strain on public programs and alleviate financial stress for countless families.

Policymakers and employers, who often play a crucial role in promoting HSA enrollment, could explore enhanced educational campaigns, clearer communication of the "triple tax advantage," and perhaps even incentives for long-term investment within these accounts. Financial institutions offering HSAs also bear a responsibility to make investment options more accessible and understandable for the average user, moving beyond the perception of the HSA solely as a "checking account" for health expenses.

In conclusion, while Health Savings Accounts are undeniably effective for managing current medical expenses, their true power lies in their potential as a retirement savings tool. By shifting the paradigm from immediate spending to strategic, long-term investment, millions of Americans could significantly bolster their financial resilience against the escalating costs of healthcare in their golden years, securing a more comfortable and less stressful retirement. The challenge now lies in bridging the awareness gap and empowering HSA holders to fully unlock the considerable benefits these unique accounts offer.
