Employers Own Healthcare. Whether You Like It or Not.

How a decision of wartime economics became an annual $1.5 trillion employer obligation — and what your business should do about it.

An Unforeseen Consequence of an Unrelated Decision

It started as a loophole.

In October 1942, President Roosevelt signed an executive order freezing wages across the American economy to prevent wartime inflation. Employers could no longer compete for scarce workers by offering higher salaries. But the National War Labor Board left one door open: fringe benefits — including health insurance — were exempt from the wage freeze.

Employers walked through it. What had been a rare perk offered by only the most progressive companies suddenly became a competitive necessity. By 1943, the War Labor Board had formally ruled that employer contributions to health insurance did not count as wages and were not subject to income tax. The arrangement that would define American healthcare for the next eight decades had been born — not through grand policy vision, but through a policy workaround.

The postwar period locked it in. The 1948 IRS ruling exempted employer-sponsored health benefits from income taxation entirely. The Internal Revenue Code of 1954 formalized the tax deduction for employer contributions. Coverage exploded: from roughly 9% of Americans in the early 1940s to more than half the population by the mid-1950s.

From Incentive to Mandate

For decades, offering health insurance was a choice — a competitive tool that smart employers used to attract and retain talent. The tax advantages made it attractive. Union negotiating power made it expected in many industries. By the 1970s and 1980s, as healthcare costs began their sustained climb, employers found themselves managing an increasingly expensive benefit that had become a standard employment expectation.

Then came the legislative mandate.

The Affordable Care Act of 2010 transformed employer-sponsored health insurance from a market convention into a legal obligation for companies with 50 or more full-time equivalent employees. Under the ACA's Employer Shared Responsibility Provision — implemented in 2015 for large employers and 2016 for those with 50 to 99 employees — applicable large employers must offer health coverage meeting minimum value and affordability standards to at least 95% of their full-time workforce, or face IRS penalties.

What began as an accidental wartime loophole had become a federal compliance requirement. By law, employers now are responsible for the provision of healthcare. It isn't something employers asked for. Regardless, they own it.

The Scale of What You Own

Today, employer-sponsored insurance covers 154 million people under the age of 65 — more than Medicare and Medicaid combined. Private health insurance spending reached $1.5 trillion in 2023, the large majority of it employer-sponsored, according to CMS National Health Expenditure data. Average annual premiums in 2025 reached $9,325 for single coverage and $26,993 for family coverage. Premiums increased 5% for single and 6% for family coverage in 2025, outpacing both wage growth (4%) and general inflation (2.7%).

Harvard Kennedy School researchers have documented what most CFOs already feel: healthcare is the second-largest expense in the operating budget of most companies, after wages.

That is the scale of what employers inherited from a 1942 wartime loophole. A multi-trillion-dollar system, built on a tax exemption, locked in by decades of convention, formalized by federal mandate — and managed by most employers with a renewal form and a broker call.

Ownership Without Strategy

The problem is not that employers own healthcare. The problem is that most employers own it passively.

They renew the same plan year after year. They accept premium increases as inevitable. They assume their broker is strategically managing costs — when in reality the broker's commission scales with the premium and the insurer's margin grows with every renewal. The renewal carousel keeps turning.

Consider what it would mean to apply the same strategic discipline to healthcare that employers apply to every other major cost center. Finance has a CFO who fights for every margin point. Legal has a general counsel who reads every contract. Operations has a VP who benchmarks every logistics cost against the market. Healthcare — a cost comparable in scale to all of these — has, in most organizations, an HR director doing her best with tools she was never trained to use.

The ACA made you a mandatory participant in this system. What it did not provide was the physician expertise, the clinical infrastructure, or the data platform to manage it. That is the gap One3 was built to fill.
