More than two-thirds of Americans—at least 68%—do not have a Health Savings Account, even though these accounts offer significant tax advantages that could strengthen both healthcare finances and retirement security. For eligible workers with high-deductible health plans, HSAs provide a triple tax benefit: contributions are tax-deductible, growth is tax-free, and withdrawals for qualified medical expenses avoid taxation entirely. Yet the vast majority of eligible Americans never open one. Consider a worker aged 45 with family coverage under a high-deductible plan who contributes $3,650 annually to an HSA; over 20 years at a conservative 5% annual return, that account could grow to approximately $130,000—a tax-sheltered resource for medical expenses in retirement. Instead, millions of eligible workers leave this opportunity unused.
The gap between HSA eligibility and actual adoption reveals a disconnect between available tax incentives and individual financial behavior. Workers cite confusion about account rules, complexity in understanding eligibility, uncertainty about medical expense reimbursement deadlines, and skepticism about whether HSAs make sense for their situations. Yet the cost of inaction compounds annually. An American family that forgoes HSA contributions over a 20-year career loses not just the tax deductions themselves, but also decades of tax-free compound growth—a significant financial loss masked by the simplicity of just not opening the account. Understanding why so many Americans skip HSAs matters for anyone approaching retirement or managing healthcare costs in later years. The decision to use—or ignore—an HSA today shapes available resources for medical expenses tomorrow, when healthcare spending often peaks.

Why Do So Many Americans Skip Health Savings Accounts Despite the Tax Benefits?
The gap between HSA eligibility and adoption stems from multiple barriers, beginning with baseline awareness. Many workers enrolled in high-deductible health plans do not realize they are eligible for HSAs, or they conflate HSAs with Flexible Spending Accounts (FSAs), which operate under different rules and expire annually. Employers, too, sometimes fail to promote HSAs, either because payroll systems do not integrate HSA offerings or because human resources departments prioritize explaining more visible benefits. A worker switching jobs or changing coverage mid-year may never receive clear notification of HSA eligibility, missing the window to set up contributions before the plan year begins.
Complexity in understanding withdrawal rules and investment options deters others. HSA funds can be invested in stocks, bonds, or mutual funds—but only after exceeding a certain minimum balance, and only with the account provider’s approved menu of investments. Confusion about whether a medical expense qualifies for tax-free withdrawal, or anxiety about maintaining receipts for years to prove eligibility, makes some workers reluctant to commit. Additionally, workers with chronic health conditions or frequent medical visits may feel that their high-deductible plan demands they spend money immediately on healthcare, leaving nothing available to deposit into an HSA—a rational short-term calculation that overlooks the long-term accumulation benefit for retirees.
The Hidden Cost of HSA Avoidance and Account Abandonment
The financial impact of not contributing to an hsa extends far beyond the current year’s forgone tax deduction. Someone earning $70,000 annually in a 24% federal tax bracket who contributes $3,650 to an HSA saves $876 in federal taxes that year. Over a 25-year career, that forgone deduction alone means $21,900 less in tax savings—before accounting for state income taxes, which can add another 5-10% savings. The compounding loss grows exponentially when factoring in investment returns. A HSA invested in a balanced index fund averaging 6% annually turns a $3,650 annual contribution into roughly $390,000 over 30 years; the same money in a taxable brokerage account grows to approximately $270,000 after accounting for capital gains taxes, a difference of $120,000 in purchasing power.
A critical limitation of HSA adoption is that account holders must maintain individual discipline or lose the tax advantage. Many HSA owners make withdrawals for routine medical expenses in the same year they contribute, treating the account as a high-deductible plan co-pay fund rather than a long-term investment vehicle. While this is legal, it defeats the purpose of accumulation. Others abandon their HSAs when changing jobs or insurance plans, cashing them out and triggering taxable income. Some account holders simply forget they have an HSA after years of employment changes, and the account sits dormant at an old plan provider, eventually charged with maintenance fees that erode the balance. The psychological burden of managing yet another financial account—tracking eligibility, monitoring medical expenses, documenting withdrawals—means even informed workers sometimes choose simplicity over tax savings.
The Medical Inflation Mismatch: Why Healthcare Costs Make HSAs Harder to Fund
American healthcare costs have risen at rates well above general inflation, making it increasingly difficult for workers to maintain discretionary income to contribute to an HSA. A worker enrolled in a high-deductible plan may face a $2,000 individual deductible or $4,500 family deductible; if actual healthcare usage is high—due to chronic illness, multiple dependents, or unexpected surgery—that deductible consumption leaves little financial margin for voluntary savings. In 2024, the average family premium for employer-sponsored health insurance exceeded $23,000 annually, shared between employer and employee; adding medical expenses on top of insurance premiums and other living costs makes HSA contributions feel like an unaffordable luxury. The timing challenge compounds the problem.
HSA contributions are most valuable when made early in a career, giving decades for growth. Yet younger workers, who have the longest time horizon for accumulation, often have the lowest incomes and highest competing financial demands—student loans, rent, childcare, emergency savings. By the time a worker reaches mid-career with discretionary income, they may have already spent fifteen years not contributing to an HSA. Retirees, who face the highest healthcare costs and could most benefit from accumulated HSA funds, cannot make new contributions once they enroll in Medicare. The window for building HSA assets is narrow and misaligned with workers’ actual financial capacity and life-stage medical needs.
How HSA-Ineligible Insurance Plans Lock Millions Out of the Opportunity
A substantial portion of the 68% figure reflects Americans who simply are not eligible for HSAs because their insurance plans do not qualify. A high-deductible health plan, the prerequisite for HSA eligibility, is defined as a plan with a minimum deductible and a cap on out-of-pocket spending; plans with lower deductibles, health maintenance organization (HMO) plans, or preferred provider organization (PPO) plans with copays rather than deductibles do not qualify. Many workers, particularly those with chronic conditions or who value predictability in healthcare costs, choose lower-deductible plans from their employer’s menu, automatically disqualifying themselves from HSAs. Others work for small employers that do not offer high-deductible plans at all, effectively removing HSA access. The trade-off between plan design features and HSA eligibility deserves examination.
A high-deductible plan with an attached HSA may offer lower premiums and greater tax savings, but it shifts financial risk onto the individual until the deductible is met. A worker considering this trade-off must be comfortable potentially paying thousands out-of-pocket for medical care before insurance protection activates. Those who value lower out-of-pocket predictability and choose low-deductible plans sacrifice the HSA option entirely. Neither choice is universally optimal—it depends on personal health history, risk tolerance, and confidence in the ability to fund medical expenses if needed. However, the asymmetry matters: low-deductible plan enrollees lose a tax-advantaged savings option, while high-deductible plan enrollees gain one. The most financially vulnerable may end up in low-deductible plans due to cost constraints, further limiting wealth-building opportunities.
Common Misconceptions and Withdrawal Pitfalls That Deter HSA Participation
A widespread misunderstanding treats HSAs as use-it-or-lose-it accounts like FSAs, causing workers to avoid opening them. FSAs, which are funded through pre-tax payroll deductions, have a strict “use it or lose it” rule—any money not spent by year-end expires (with a limited grace period or carryover option, depending on plan design). HSAs are completely different: they carry over indefinitely, never expire, and belong entirely to the account holder even if they change jobs or insurance plans. This misunderstanding alone likely deters significant HSA adoption. A worker who believes they must spend down their entire HSA balance every year to avoid losing it will rationally avoid contributing; they may already struggle to predict annual medical expenses or may have years with minimal healthcare needs.
A second misconception involves the two-step withdrawal process. HSA money can be withdrawn and reimbursed for any qualified medical expense incurred after the account opened, but the expense does not need to occur in the year of withdrawal. A savvy account holder could pay medical expenses out-of-pocket and save the receipts, allowing HSA funds to remain invested and compounding for decades, then withdraw funds decades later using historical receipts to prove expense eligibility. Many account holders never discover this strategy and instead withdraw funds annually for current-year expenses, missing the accumulation opportunity. Additionally, non-medical withdrawals before age 65 incur both income tax and a 20% penalty, while after age 65 they face only income tax—a harsh penalty for withdrawals during the working years that discourages some from opening accounts at all.
The Employer’s Role in HSA Adoption and Abandonment
Employers significantly influence HSA adoption through plan design, communication, and financial incentives. Some employers contribute generously to employee HSAs, matching contributions up to a certain percentage or providing employer-funded seed balances; these contributions are a tax-free benefit to employees and typically drive higher adoption rates. Other employers mention HSAs only in fine print within open enrollment materials, failing to highlight the tax advantages or account mechanisms. A few employers actively discourage HSAs by offering only limited provider options, high per-transaction fees, or no investment options, making HSAs feel burdensome rather than beneficial.
When a worker changes jobs, HSAs are often left behind at old institutions because the new employer’s HSA is through a different provider; consolidating multiple HSA accounts is possible but requires active effort, and many workers never bother. In reality, employers face their own economic incentives that may not align with employee HSA adoption. Some employers save money by offering high-deductible plans (lower premiums), but they do not necessarily contribute to HSAs; the tax savings flow to employees, not the company. If an employer is cost-focused rather than employee-benefit focused, they may opt for lower-deductible plans that eliminate the HSA option entirely. Conversely, employers in competitive talent markets often use HSA matching or contributions as a differentiator, making HSA adoption one more factor in the employee benefits landscape that varies widely across employers.
The Retirement Readiness Implications of Low HSA Adoption
For retirement planning, the widespread lack of HSA adoption represents a missed accumulation tool during the decades when tax-advantaged saving matters most. Medicare does not cover all healthcare costs; retirees typically face ongoing out-of-pocket expenses for deductibles, copays, supplemental insurance premiums, dental care, vision care, hearing aids, and long-term care. The average 65-year-old couple retiring in 2024 would need approximately $315,000 saved specifically for healthcare expenses in retirement, according to estimates from major financial planning firms. An HSA operates as a stealth retirement account for healthcare costs: withdrawals after age 65 for Medicare premiums, supplemental insurance, or any medical expenses avoid the 20% early withdrawal penalty, making HSAs a uniquely flexible tool for healthcare-specific retirement saving.
The fact that 68% of eligible Americans are not using this tool means they are accumulating this healthcare-specific wealth through fully taxable accounts or not at all. The forward-looking implication is that retirement readiness for Americans without HSA assets will increasingly depend on other savings vehicles, Social Security, and out-of-pocket spending. Workers who do accumulate in HSAs gain a meaningful financial advantage during years when healthcare is expensive and income may be fixed. For those approaching retirement without an HSA, the opportunity has largely passed. Looking ahead, as healthcare inflation continues and Medicare coverage becomes less comprehensive, the underutilization of HSAs may become increasingly visible as a source of retirement financial stress for those who missed the window to accumulate.
Conclusion
The fact that at least 68% of Americans do not have a Health Savings Account, despite their powerful tax advantages, reflects a combination of structural barriers, awareness gaps, and behavioral factors. For those who are eligible—enrolled in high-deductible health plans—HSAs offer a rare opportunity for triple tax-advantaged saving that can meaningfully strengthen retirement healthcare security. The inaction of the majority is not irrational given the complexity and misconceptions surrounding these accounts, but it is costly. Workers in their 20s, 30s, and 40s who delay or skip HSA contributions are giving up decades of tax-free growth on funds that will likely be needed for medical expenses in retirement.
If you are enrolled in a high-deductible health plan and do not have an HSA, the financial case for opening one is straightforward: confirm your eligibility with your benefits administrator, understand the account rules and withdrawal process, and consider even modest annual contributions as a long-term healthcare savings strategy. If you already have an HSA but have been using it as a pay-as-you-go fund, consider shifting toward accumulation by paying eligible medical expenses out-of-pocket and allowing HSA funds to invest and compound. For employers and financial advisors, the challenge is to demystify HSAs and reduce the friction between eligibility and enrollment. The tax dollars forgone by the 68% without HSAs are losses that, compounded over careers, reshape retirement readiness and healthcare security in later life.
