Pennsylvania Supreme Court Rules Stormwater Charge Is a Tax, Raising Specter of Higher Bills for Businesses

HARRISBURG, Pa. — The Pennsylvania Supreme Court issued a landmark decision on April 30 that classifies a municipal stormwater charge as a tax rather than a fee for service. The ruling, which resolves a years-long dispute between the Borough of West Chester and a state university, has immediate and significant financial implications for businesses, landlords, and homeowners across the Commonwealth, who may now face higher bills to cover costs no longer paid by tax-exempt entities.

For Pennsylvania business owners, this ruling immediately complicates local tax planning and budgeting. A charge once treated as a utility-style fee now carries the weight and implications of a property tax, demanding closer scrutiny of financial obligations and commercial lease agreements.

The case, Borough of West Chester v. West Chester University of Pennsylvania, centered on the university’s refusal to pay stormwater management charges levied by the borough starting in 2016. As a state-owned and tax-exempt institution, the university argued the charge was a local tax from which it was immune. The borough contended it was a fee for a specific service—managing the stormwater runoff from the university's property. The Supreme Court ultimately sided with the university, affirming a 2023 Commonwealth Court decision.

In its opinion, the court reasoned that the charges were not reasonably proportional to a direct service or benefit received by the property owner. Instead, the revenue is used to fund broad public works projects, such as improving water quality and mitigating flooding, which benefit the entire community. According to the court, because these projects provide a general public benefit rather than a discrete service to the payer, the charge functions as a tax.

This legal distinction is critical. As a result of the ruling, tax-exempt organizations—including state and federal government properties, public schools, universities, and institutions of purely public charity—are now likely exempt from these stormwater charges across Pennsylvania. This creates a significant revenue gap for municipalities that rely on these funds to maintain and upgrade aging stormwater infrastructure and comply with federal environmental mandates like the Clean Water Act.

According to environmental groups like the Chesapeake Bay Foundation, the decision is a major setback for clean water efforts. Stormwater fees are designed to pay for projects that control polluted runoff from impervious surfaces like parking lots, roads, and rooftops. Without this funding mechanism applied broadly, the financial burden shifts to the remaining pool of non-exempt property owners.

In our experience, when a revenue stream is reclassified like this, municipalities act to protect their budgets, and the burden often shifts directly to the commercial sector. Businesses must now re-evaluate their liabilities, especially those with large impervious surfaces like parking lots and rooftops. Landlords and tenants will need to carefully review lease terms to determine who is responsible for this newly defined tax.

The financial consequences extend to commercial real estate leases. Legal experts note that many lease agreements require tenants to pay for all property taxes. With stormwater charges now defined as a tax, this cost will likely be passed on to commercial tenants in properties with such lease structures, representing a new and potentially substantial operating expense.

However, the court's decision was not a blanket declaration that all stormwater fees in the state are taxes. The ruling in the West Chester case was based on the specific structure of that borough's program. Legal analysis from McNees Wallace & Nurick suggests that the factual record of how a municipality calculates and applies its fees is dispositive. A different municipality with a fee structure more closely tied to the direct cost of service for a specific property might survive a similar legal challenge. This nuance creates a landscape of uncertainty and potential for further litigation across the state.

This issue is not unique to Pennsylvania. Courts in other states have grappled with the same question, sometimes reaching different conclusions. In a notable Michigan case, an appellate court upheld Ann Arbor's stormwater charge as a valid fee because its primary purpose was regulatory—funding the city's compliance with its federal National Pollution Discharge Elimination System (NPDES) permit. The Pennsylvania court, by contrast, focused more on the general public benefit of the funded projects.

The legal nuances are complex, but the bottom-line impact for businesses is clear: a predictable operational expense may now become a more volatile and potentially larger tax liability that requires active management. On the other hand, the ruling may create new tax deduction opportunities for businesses and individuals who can now potentially treat the payment as a local tax.

Municipalities across Pennsylvania are now expected to review their stormwater management programs. They may choose to restructure their charges to be more defensible as fees or convert them into explicit property taxes. Business owners and property managers should closely monitor communications from their local governments and prepare for potential adjustments to their local tax and utility bills in the coming months.
