The ongoing debate surrounding healthcare affordability often fixates on the Affordable Care Act and its subsidies, particularly during open enrollment periods. However, a broader, largely unacknowledged system of federal support underpins nearly all health insurance in the United States, extending far beyond the ACA marketplace. While headlines focus on fluctuating premium assistance, the reality is that the vast majority of Americans – those with employer-sponsored, Medicare, and Medicaid coverage – benefit from substantial, if often invisible, taxpayer subsidies. Understanding the scope of these existing supports is crucial, not just for evaluating the ACA’s impact, but for any serious conversation about healthcare finance reform.
The scale of these subsidies is immense. In 2026, Medicare, the second-largest federal program after Social Security, will draw over $1.1 trillion in funding, with roughly half coming from general federal funds. Medicaid, covering over 70 million low-income individuals, will cost over $918 billion annually, financed through a 65/35 split between the federal government and states. These figures, while substantial, represent direct government spending. A less visible, yet equally significant, subsidy flows through employer-sponsored insurance, a system covering at least 154 million people under age 65 – dwarfing the 22.9 million enrolled in ACA plans this year. Larry Levitt, executive vice president for health policy at KFF, succinctly points out that “the vast majority of people with health insurance get some kind of federal subsidy for it, from Medicaid to Medicare to the ACA to employer-sponsored insurance.”
This employer-sponsored support takes the form of tax breaks, a policy originating during World War II as a workaround to wage controls and formally codified in 1954. Employers can deduct the cost of health coverage as a business expense, and employees are not taxed on the value of their benefits. The Joint Committee on Taxation and the Congressional Budget Office estimate this “exclusion” will amount to $451 billion in lost federal revenue this fiscal year alone – making it the single largest tax expenditure in the federal budget. While employees often contribute to their premiums, the portion provided by the employer is effectively a tax-free benefit, worth hundreds or even thousands of dollars annually, particularly for those in higher tax brackets. This isn’t a government check directly to individuals, as Michael Cannon, director of health policy studies at the libertarian Cato Institute, notes: “It’s a world apart from Medicare, Medicaid, and Obamacare — from the government writing checks to people.”
The existence of this massive tax break isn’t necessarily controversial – many stakeholders, including labor unions and employers, argue it encourages companies to offer health insurance. However, its impact is complex and contested. Opponents argue it distorts the market, incentivizing both employers and employees to choose more expensive plans, driving up overall healthcare spending. Some economists also contend that the tax exclusion disproportionately benefits wealthier workers and that the funds could be better utilized as direct wage increases. The debate is further complicated by the fact that the tax break is “baked into the tax system,” as Levitt describes, making it a less salient issue for many insured individuals who simply perceive a premium payment rather than a substantial tax benefit.

The potential for change looms, fueled by the growing federal deficit. Employer groups are increasingly concerned that the tax break could be targeted for reform, a move that could significantly alter the landscape of employer-sponsored insurance. While past attempts to cap or eliminate the exclusion have failed – it’s been “a bipartisan target on its back for 40 years,” according to Paul Fronstin, a director at the Employee Benefit Research Institute – the pressure remains. Any alteration would inevitably create winners and losers, potentially leading to increased taxes for workers and a re-evaluation of employer-sponsored coverage. Elizabeth Mitchell, CEO of the Purchaser Business Group on Health, cautions that eliminating the tax incentive could prompt some employers to drop coverage altogether, given the escalating costs of healthcare.
The fundamental question remains: what is the optimal way to subsidize healthcare in the United States? The current system, a patchwork of direct spending and tax breaks, is opaque and often counterintuitive. As policymakers grapple with the federal deficit and the ongoing challenge of healthcare affordability, we should expect renewed scrutiny of these hidden subsidies. The critical question for the coming year isn’t simply whether ACA subsidies will be extended, but whether the broader, more substantial system of tax breaks for employer-sponsored insurance will remain untouched – and whether that’s truly in the best interest of both individuals and the nation’s financial health. Will employers continue to prioritize health benefits as a recruitment tool even without the tax advantage, or will we see a shift towards higher wages and individual market plans? The answer will shape the future of healthcare access for millions of Americans.
