Property Off the Tax Roll

When the Biggest Landowner Pays Nothing

A university that owns a city block pays no property tax on it. That is not an oversight or a loophole — it is the intended operation of nonprofit tax exemption under state law, which removes charitable institutions from the municipal tax base as a matter of policy. For a small city whose largest employer also happens to be its largest landowner, the fiscal arithmetic can be severe.

The exemption is grounded in state constitutions and statutes, not federal law, which is why its scope varies considerably across the country. Most states exempt all real property owned by a nonprofit and used for its charitable purpose — classrooms, laboratories, libraries, administrative buildings, athletic facilities. Some states draw harder lines: property leased to commercial tenants or used for activities unrelated to the educational mission may remain taxable, but the boundary is contested and litigation is common. In practice, the bulk of a major research university's campus sits permanently off the municipal tax roll.

The scale is not trivial. Several American cities — Providence, New Haven, Cambridge, Pittsburgh, Baltimore — host research universities whose tax-exempt holdings represent a substantial fraction of the total assessed value within city limits. When that property also concentrates in the most commercially desirable neighbourhoods, the effective tax rate on remaining private owners rises to compensate, or city services contract, or both.

PILOT agreements — Payments In Lieu of Taxes — are the most common instrument cities use to recover some portion of that lost revenue. A PILOT is a voluntary payment negotiated between a municipality and a tax-exempt institution; it carries no legal compulsion and is not enforceable as a tax. Boston has operated one of the longer-running university PILOT programmes, pressing its major institutions to contribute toward a city-defined formula. New Haven has periodically renegotiated agreements with Yale. The amounts paid under these agreements are consistently well below what the properties would generate if fully taxed — estimates in various cities have placed PILOT receipts at between ten and thirty percent of theoretical tax liability — and the agreements lapse, are renegotiated, and sometimes collapse when a new administration arrives on either side of the table.

The voluntary nature of PILOTs is their structural weakness. A university with substantial endowment and political influence can decline to pay more, delay renegotiation, or substitute in-kind contributions — community programmes, transit passes, workforce initiatives — that are difficult to value and easy to dispute. City officials who depend on the university as an economic anchor have limited leverage, and state legislatures that might mandate stronger PILOT frameworks have generally declined to act, in part because universities are effective lobbyists at the statehouse.

The fiscal consequences fall unevenly. Neighbourhoods immediately adjacent to expanding campuses lose taxable parcels as universities acquire property, while bearing increased traffic, parking pressure, and demand for city services that the institution does not fund. Homeowners in those neighbourhoods subsidise the exemption through their own tax bills without receiving a proportionate benefit.

None of this is hidden. Municipal budget documents record the exemptions; assessors publish their rolls; PILOT agreements, where they exist, are public contracts. The policy debate turns not on disclosure but on whether the charitable and economic contributions universities make to their host cities — jobs, anchor-institution stability, cultural amenities — offset the tax revenue permanently removed from local government. That calculation differs city by city, and no state has yet devised a formula that satisfies both sides for long.
