The U.S. leads the developed world in health care spending. Hospital charges are high, insurance premiums continue to rise, and medical expenses weigh heavily on families. While many political debates focus on market failure, a deeper factor lies elsewhere: the tax code.
The exclusion of employer-sponsored insurance from taxable income has had a profound effect on the system. It shifted financial responsibility away from individuals, tied coverage to employment, and lowered the incentive to shop for value. Consequently, patients rarely see the actual cost of their care.
Tracing the development of this tax structure clarifies why health care in America operates so differently from other markets.
The Core Problem
In most industries, buyers make spending decisions with their own money. This simple dynamic keeps prices competitive and encourages value. Health care in the United States works very differently.
Roughly 90 cents of every dollar spent on health care comes from a third party, usually a private insurance company or the government. Patients receive treatment, but another entity pays the bill.
This structure weakens the normal relationship between a service provider and a customer. Without direct financial responsibility, patients rarely compare prices or question whether a treatment is necessary.
Several consequences follow:
– Prices become difficult to understand or compare.
– Competition between providers weakens.
– Spending rises without strong pressure to control costs.
When the person using the service does not feel the cost directly, demand often increases while price discipline disappears.
The Tax Policy That Built Employer-Based Insurance
The modern health insurance system did not appear by accident. Its foundation dates back to early decisions within the U.S. tax code.
Economist Michael Cannon of the Cato Institute has documented that the tax exclusion for employer-sponsored insurance dates back nearly as far as the federal income tax itself. Early Treasury rulings allowed companies to provide health benefits without counting them as taxable wages.
The policy gained momentum during World War II. Wage controls prevented companies from raising salaries to attract workers. Employers began offering health insurance benefits instead, since these benefits were not restricted by wage caps.
This workaround became common across industries.
Health insurance purchased by employers did not expand dramatically until after wage controls ended in 1953. Shortly afterward, Congress officially codified the tax exclusion in 1954, cementing employer-sponsored insurance as the dominant model for American workers.
Few policymakers at the time predicted how deeply this decision would shape the health care economy.
The Financial Cost of the Tax Exclusion
The employer insurance tax break now represents one of the largest provisions in the U.S. tax code.
Government projections estimate that the exclusion will reduce income and payroll tax revenue by about $487 billion in a single year. That figure makes it three times larger than the next biggest tax break available under federal law.
Yet the fiscal impact is only part of the story. The policy also shaped economic behavior for decades.
The exclusion encouraged employers to compensate workers with insurance rather than higher wages. As a result:
- Workers often receive benefits instead of cash income.
- Insurance plans grow more comprehensive because the benefits remain tax-free.
- Patients become less sensitive to the cost of care.
Over time, this structure reduced direct consumer spending on medical services. Without that pressure from patients, prices continued to rise.
How the System Tied Insurance to Employment
Employer-sponsored insurance now dominates U.S. health care. Millions of workers gain coverage through their jobs, and losing a position often means losing health benefits.
This setup has several long-term consequences.
First, workers may hesitate to change jobs if the new employer doesn’t offer comparable insurance, a phenomenon economists call “job lock.”
Second, employers largely control the design of health plans. Employees rarely choose coverage in the same way they select other financial products.
Third, wages are often lower because companies provide health benefits in lieu of higher pay.
These patterns developed gradually but now shape how most Americans access medical coverage.
The Ideal Tax Structure (And Why It Doesn’t Exist)
Many economists argue that an efficient tax system should follow a simple principle: income should be taxed once, without exemptions that favor particular types of spending.
Under that system, employer-provided insurance would be treated like salary and subject to tax. Removing the exclusion could encourage individuals to purchase insurance directly and compare prices more carefully.
However, eliminating the tax break would be politically complicated. Millions of Americans rely on employer-based coverage, and abrupt changes could disrupt existing plans. For this reason, policy discussions often focus on incremental adjustments rather than full reform.
Health Savings Accounts as a Partial Fix
One approach gaining attention involves Health Savings Accounts (HSAs). These accounts let individuals set aside pre-tax income for medical expenses.
Funds in an HSA can be used for treatments, prescriptions, and other qualified costs. Because the money belongs to the patient, spending decisions become more deliberate.
Studies show several behavioral effects among HSA participants:
- Lower overall health care spending
- Greater engagement in wellness programs
- Increased attention to the price of services
Some analysts caution that these patterns may partly reflect the characteristics of people who choose HSA plans rather than the plans themselves. Still, the underlying principle remains simple: when individuals spend their own funds, they tend to ask more questions about value.
Limits on Who Can Use HSAs
Despite their potential, HSAs currently operate under strict eligibility rules.
To open an HSA, an individual must enroll in a high-deductible health plan (HDHP). This requirement excludes many Americans who have traditional employer plans or other forms of coverage.
As a result, millions of people cannot access the same tax advantages that encourage cost awareness.
Legislation known as the 2025 One Big Beautiful Bill Act made some improvements. The law expanded:
– Annual HSA contribution limits
– The range of medical expenses that qualify for tax-free spending
Even with these adjustments, the main restriction remains in place. HSA eligibility still depends on the type of insurance plan rather than the consumer’s needs.
Consumer Control Beyond Traditional Insurance
Many Americans already seek alternatives to standard insurance markets. Some individuals choose short-term health plans, health-sharing arrangements, or other models that provide greater control over spending.
These decisions often reflect a desire to manage medical costs directly rather than rely on complex insurance structures.
A broader HSA system could support this approach. Allowing individuals to accumulate medical savings over time would strengthen the connection between patients and providers.
Greater financial responsibility at the consumer level tends to encourage price transparency, comparison shopping, and cost discipline across the market.
The high price of U.S. health care is closely linked to a tax rule that excludes employer-sponsored insurance from taxable income. Over time, this policy tied insurance to jobs, reduced direct wages, and distanced patients from the real cost of care.
Expanding tools like Health Savings Accounts could help restore consumer involvement in medical spending and encourage better price awareness across the system.
