Tax-exempt hospitals represent a foundational pillar of medical care across the United States, providing a substantial share of inpatient and outpatient services. Of the roughly 6,100 hospitals operating nationwide, nearly half are classified as nongovernment, tax-exempt community hospitals. However, as independent medical facilities continue to consolidate into larger health systems and their cumulative revenues rise significantly, policymakers and economists are increasingly examining the financial scale of these institutional exemptions. As these systems expand, the financial value of their tax-exempt status—and the corresponding cost of forgone government revenue—continues to grow, sparking a national debate among lawmakers from both major political parties over accountability, economic fairness, and the true value of community benefits.
Not-for-profit hospitals generally enjoy broad exemptions from federal income taxes, state income taxes, and local property taxes. In addition to these primary exemptions, they frequently utilize tax-exempt bond financing for large-scale capital projects and benefit from tax-deductible charitable donations made by individuals, corporations, and philanthropic foundations. Over the years, numerous academic and policy studies have attempted to calculate the monetary value of these exemptions. Recent economic estimates covering the period from 2018 through 2022 place the value of the federal corporate income tax exemption for hospitals alone between $8.3 billion and $11.5 billion per year. When factoring in other tax privileges, broader studies suggest the total annual value is substantially higher.
In response to these growing figures, lawmakers in Washington have subjected the hospital tax exemption to intense scrutiny. Questions have been raised regarding whether the community benefits delivered by these massive tax-exempt entities genuinely justify the scale of the tax relief they receive. Discussions on Capitol Hill have ranged from requiring more detailed and transparent public reporting on community benefits to potentially limiting tax exemptions altogether for the largest, most financially robust hospital systems.
To evaluate the fiscal impact of these policy proposals, the Tax Foundation has modeled and analyzed several options designed to reform the tax treatment of exempt hospitals. According to these projections, applying the standard 21 percent federal corporate income tax to large hospital systems would generate approximately $147.6 billion in federal revenue over a ten-year window. Meanwhile, more targeted reform measures—such as levying taxes specifically on net investment income or recapturing tax benefits that exceed a hospital’s reported community benefits—would yield smaller amounts of revenue.
Choosing to alter the tax treatment of these institutions involves a series of complex policy trade-offs. Lawmakers must navigate difficult decisions, including determining how many hospital systems would be covered under new thresholds, establishing standardized definitions for community benefits, and deciding which specific tax privileges should be prioritized during a legislative overhaul.
A Brief History of Hospital Tax Exemptions
The legal framework governing tax-exempt organizations dates back more than a century. A tax-exempt entity is generally excused from paying federal income tax on revenue tied directly to its exempt purpose. The earliest iteration of a corporate income tax exemption emerged in 1894 with the enactment of a temporary corporate income tax, which was subsequently struck down by the Supreme Court the following year. Congress later exempted charitable organizations from an excise tax on corporations in 1909, a provision that carried forward into the modern federal income tax system first established in 1913.
While hospitals were not explicitly named in the tax statutes of 1909 or 1913, they historically received tax-exempt status as nonprofit institutions affiliated with religious groups or philanthropic foundations. In 1956, a pivotal revenue ruling from the Internal Revenue Service established the "charity care" standard, requiring hospitals to provide uncompensated care to individuals unable to pay as a condition for maintaining their federal tax exemption. The IRS later replaced this ruling in 1969 with the broader "community benefit" standard, which remains the governing framework today.
Modern health-care systems, however, bear little resemblance to the smaller, localized institutions of a century ago. Today’s major health networks operate sophisticated, multibillion-dollar enterprises. Data from recent IRS filings underscore the immense financial footprint of the sector, with thousands of hospital filers collectively generating tens of billions of dollars in net income annually. If the hospital tax exemption were eliminated, a significant portion of this net income would become subject to the standard 21 percent U.S. corporate income tax rate, alongside state corporate income taxes, local property taxes, and federal unemployment taxes.
Over the past decade and a half, various research institutions and policy organizations have attempted to quantify the total value of these tax exemptions. Studies published between 2011 and 2022 by organizations such as the Kaiser Family Foundation, the Tax Policy Center, Health Affairs, and the Lown Institute have produced varying estimates based on differing methodologies, data years, and definitions of tax benefits. While these figures fluctuate depending on the scope of the analysis, they consistently highlight the immense scale of public support delivered to the nonprofit health sector through the tax code.
Revenue Effects of Proposed Tax Reforms
To understand the fiscal implications of altering this framework, the Tax Foundation modeled the conventional revenue effects of five distinct reform options targeting large hospital systems. Each proposed option is structured to apply specifically to hospital systems with an average total revenue of $1 billion or more over the three preceding years, with the threshold indexed for inflation in future years. Applying a $1 billion threshold would initially cover hundreds of major health systems, accounting for the vast majority of the sector’s overall revenue, income, assets, bonds, and philanthropic gifts.
Under these economic projections, standardizing tax rules across the health sector would generate varying amounts of revenue depending on the specific mechanism chosen. However, the macroeconomic and budgetary outcomes depend heavily on the design parameters selected by lawmakers.
For instance, Congress could choose to levy a 21 percent income tax on large systems based on book income—derived from financial statements—rather than traditional taxable income. Modeling indicates that a 21 percent book income tax on large hospital systems would increase federal revenue by over $200 billion on a conventional basis over ten years, significantly higher than the revenue raised under a traditional taxable income base. This divergence is driven primarily by the treatment of capital investments, such as accelerated depreciation rules used in financial reporting compared to standard tax deductions.
Alternatively, lawmakers could apply the 21 percent income tax directly to individual hospital entities that surpass the revenue threshold rather than consolidated parent systems. Because fewer individual facilities would meet the threshold independently compared to consolidated networks, this approach would yield lower total revenue.
Other explored options include excise taxes on net investment income. Rates of 4 percent or 8 percent would mirror the top tiers of the existing tax structure applied to large university endowments, while a 21 percent rate would align directly with the corporate tax rate. Policymakers could also consider whether to implement a graduated rate structure, though economists note that higher marginal rates can inadvertently increase incentives for corporate restructuring and tax avoidance.
Additional proposals involve restricting the deductibility of charitable donations made to large hospital systems, either through a full denial or an incremental cap, and limiting tax-exempt bond financing for future capital projects. Because prospective limits on bond financing would exempt existing debt and refundings, the associated revenue gain would start small and grow gradually over time as older bonds mature and new taxable debt is issued.
Another complex policy lever involves the recapture of tax benefits when they exceed the value of the community benefits provided by a health system. The fiscal impact of a recapture mechanism depends entirely on how community benefits are defined. A narrow definition focused strictly on direct charity care yields substantially more tax revenue than a broader definition that includes Medicare and Medicaid shortfalls, educational programs, and community-building initiatives.
Design Considerations and Trade-Offs
While each reform option examined in the analysis would increase federal revenue and enhance horizontal equity between tax-exempt hospitals and for-profit health-care providers, policymakers would face significant design challenges. Any structural change must be carefully calibrated to avoid discouraging essential capital investments in medical technology, infrastructure, and patient care facilities. Preserving full expensing or robust depreciation rules within the tax code, for example, would remain a critical component of maintaining investment incentives.
Furthermore, hospitals would likely adjust their operational and corporate behavior in response to tax policy changes. Systems operating near the revenue threshold might explore corporate reorganizations, spin-offs of affiliated facilities, or mergers designed to keep consolidated entities beneath the statutory threshold. Some organizations might even consider transitioning entirely to for-profit status or seeking acquisition by for-profit entities, though such long-term behavioral shifts were excluded from the baseline revenue estimates.
From a tax policy perspective, these reform options are designed to move the federal tax code toward greater neutrality among similarly situated economic actors within the health-care sector. Applying tax rules that are already standard for most other commercial enterprises represents a logical step toward a more uniform tax base. However, as lawmakers weigh these complex choices, the specific details of legislative design will ultimately determine whether reforms successfully improve tax neutrality while minimizing unintended disruptions for health-care providers and the patients they serve.
