Americans stash funds in health savings accounts amid Medicare trust fund insolvency concerns

In 2023, the United States government estimates there were approximately 36 million Health Savings Accounts (HSAs), holding assets adding up to more than $116 billion. That’s an increase of more than 500 percent in the last 10 years.

Americans are increasingly taking control of saving and investing for their healthcare expenses using HSAs. This trend is particularly significant as it coincides with the projected depletion of the Medicare trust funds, which are expected to start in 2031.

The rise of HSAs can be seen as a response to the potential future healthcare funding gap.

Growing popularity of Health Savings Accounts


The 2003 Medicare Modernization Act gave rise to health savings accounts (HSAs), now the most popular type of consumer-driven health plan (CDHP). A CDHP is a type of health insurance plan in which individuals can use their money to pay for healthcare expenses before the insurance coverage kicks in.

HSAs combine a high-deductible health insurance plan with an account that can be funded with pretax dollars, giving carriers a tax-advantaged way to pay for eligible health care expenses.

Introduced in 2004, HSAs allow pretax contributions that grow tax-free and can be withdrawn tax-free for qualified medical expenses. These accounts complement high-deductible health plans and ease medical cost burdens. HSAs are versatile and can be used for immediate medical needs or invested for long-term financial growth and future expenses.

The Devenir HSA Research Report confirms strong asset growth in HSAs, fueled by stock market gains that led to record asset increases in 2023. Despite slowing HSA growth, there were $123 billion in HSA assets and more than 37 million accounts by the end of 2023. This figure marks a 19% rise in assets and an annual 5% increase.

The growth of HSA investing remains steady, with about 2.9 million HSAs — nearly 8% of all accounts — having at least some of their funds invested. Devenir forecasts that the HSA market will approach 44 million accounts and hold around $168 billion in assets by the end of 2026.

According to the report, employers contributed 26% of all HSA funds, with an average employer contribution of $929 per contributor. Employees provided 64% of all HSA funds, averaging $2,269 per contributor. Another 9% of all HSA funds came from individuals with accounts not linked to an employer, with an average contribution of $2,368 per contributor.

The good, bad, and ugly of Health Savings Accounts


While 80% of Americans consider health insurance a priority benefit, half are unfamiliar with HSA features. This lapse in understanding leads to missed opportunities to fully leverage benefits.

Three HSA tax advantages include:

• Tax-free contributions: Account holders contribute pretax dollars through paycheck deductions.

• Tax-free growth: All HSA account interest and earnings, such as dividends or appreciation, grow tax-free. Many HSA providers offer investment options so account holders can invest in the stock market. By the end of 2023, account holders invested 38% of all HSA assets.

• Tax-free withdrawals: Everyone can pay for their qualified medical expenses tax-free. The Internal Revenue Service determines what qualifies as qualified medical expenses based on IRS publication 502, Medical and Dental Expenses.

At age 65, consumers can utilize HSA funds for non-medical expenses, though the money is taxable. Because of this advantage, qualifying Americans can use the HSA as a retirement fund. This advantageous flexibility can incentivize those planning for retirement.

Initially, HDHPs and HSAs reduced healthcare costs by shifting healthcare spending responsibilities to individuals. However, these plans shifted expenses from employers to workers and their families instead of tackling the root causes behind high healthcare costs.

HSAs allow registrants to cover out-of-pocket costs with pretax dollars. But in 2020, the National Institute of Health reported 32% of consumers who had not contributed to HSAs could not afford to. Consequently, individuals with HDHPs seek medical attention less often.

Critics of HSAs have cited the accounts’ favor of high-income individuals and their potential for worsening racial and ethnic disparities. In 2022, the Congressional Research Service analyzed IRS data and found that tax returns with adjusted gross incomes over $500,000 were the most likely to report individual HSA contributions, while returns between $200,000 and $1 million were the most likely to report employer HSA contributions. HSA Opponents argue that this inequitable distribution of benefits exacerbates existing wealth disparities.

Additionally, HSAs sometimes act as tax shelters for wealthy account holders while offering little to improve coverage and affordability to the general population. Furthermore, HSAs pose a significant cost to the federal government — around $13 billion in 2022 and nearly $180 billion over the next decade.

Social Security and Medicare boards of trustees paint a grim picture


The 2023 annual Social Security and Medicare trust funds report indicates ongoing Social Security and Medicare financing challenges.

Current estimates reveal that the Hospital Insurance (HI) Trust Fund can cover 100% of benefits until 2031. HI trust fund reserves expire after 2031, leaving enough income to pay only 89% of scheduled benefits. This discrepancy could increase healthcare costs for individuals, boosting the need for personal healthcare savings.

Systemic changes must ensue, though lawmakers offer few options for sweeping changes that reduce or eliminate shortfalls in long-term financing. Potential solutions include increasing the tax rate, reducing benefits, or finding other sources of revenue to replenish the trust fund. While these are complex and politically sensitive issues that require careful consideration and planning, a shrinking number of HSA-holding Americans can proactively plan for the future.
