A buyer working through a Pennington purchase checks two numbers before writing an offer: the sale price and the current property tax bill. Both look final. Neither one tells the whole story.
In July 2026, homes in Pennington sold at a median price of $622,000, with the typical listing taking 67 days to find a buyer, up from 60 days the year before. Those numbers sit right there on the listing sheet. What doesn't show up anywhere on that sheet is that Pennington's property tax trajectory for the next three decades was just settled, not at Borough Hall, but in a courtroom, over a development six miles away in Hopewell Township.
The Development That Started It
In 2021, Hopewell Township approved a 30-year tax exemption, known in New Jersey as a PILOT, or payment in lieu of taxes, agreement, for Hopewell Parc, a 1,077-unit project off Scotch Road built by homebuilder Lennar. Of those units, 861 are market rate and 216 are designated affordable housing. Under the state's Long Term Tax Exemption Law, the developer doesn't pay conventional property taxes into the tax rolls. Instead, it makes a fixed annual payment that goes almost entirely to Hopewell Township's own municipal government.
What Hopewell Township Gains, Line by Line
According to figures Pennington's own council released, the PILOT pulled more than $332 million in assessed value out of Hopewell Township's tax base. Over the full 30-year term, the township is projected to collect $387 million in unrestricted PILOT revenue, roughly six times the $67 million it would have collected through conventional taxation on the same properties. Homeowners inside the development still pay close to full freight, 99.5 percent of standard tax rates for 25 of the 30 years, but that money moves through the PILOT structure rather than the ordinary channels that fund schools, the county, and the fire district.
Why the Bill Follows You to Pennington
Pennington, Hopewell Borough, and Hopewell Township share one regional school district, Hopewell Valley Regional. For decades, the three towns have split the district's costs in proportion to each town's assessed valuation against the combined total. When Hopewell Township's taxable base shrank by more than $332 million, its proportional share of school costs shrank right along with it. The difference didn't disappear. It moved to the two towns that never signed the agreement: Pennington and Hopewell Borough.
Pennington Mayor James Davy put a number on that shift publicly: an estimated $25 million or more in additional school costs pushed onto Pennington and Hopewell Borough taxpayers over the life of the 30-year deal.

Three Years in Court, One Answer in February
Pennington and Hopewell Borough sued to void the PILOT, arguing it violated school funding law and that the developer hadn't proven the exemption was necessary for the project to move forward. A trial court dismissed the case. The Appellate Division affirmed that dismissal in August 2025, ruling that municipalities have room under state law to weigh a project's benefits, including its affordable housing component, without proving a strict financial necessity. Hopewell Borough had joined the original lawsuit but stepped back before the final round, leaving Pennington to carry the last appeal alone. In February 2026, the New Jersey Supreme Court denied Pennington's petition for certification, closing three years of litigation for good.
That denial matters more to a Pennington buyer than it might first appear. It means the tax-shift arrangement is no longer a live dispute that could still be reversed. It is now a fixed feature of the town's finances for whatever remains of the 30-year term, a structural fact rather than a pending question.
The Part That Cuts the Other Way
The PILOT arrangement isn't a pure loss for Pennington households. As part of the broader agreement, Hopewell Township committed $16.1 million of its PILOT revenue toward an expansion at Bear Tavern Elementary School, one of six buildings in the regional district that Pennington's own children attend. That commitment sat in the background of the district's recent bond referendum debate. Voters rejected an $87.5 million bond in September 2024, then approved a scaled-back $84.2 million version in November 2025 after the district revised the plan based on community feedback. The $16.1 million PILOT commitment layers on top of that bond funding rather than replacing it, and will go toward paying down the district's debt service once the money is available.
What This Changes for a Pennington Buyer
None of this shows up in a home search filter. A median price and a current mill rate describe where things stand this month. They don't explain why one town's share of a regional school budget might grow faster than its own population or assessed value, especially when a neighboring town has committed a large share of new construction to a 30-year exemption.
For someone comparing Pennington against other towns in the Hopewell Valley, the practical takeaway isn't that Pennington is a worse buy. It's that a full picture of long-term carrying costs here means asking a sharper question than what's printed on a single listing's tax line: what share of the regional school budget is this town absorbing, and is that share holding steady or climbing. That figure isn't something a portal calculates. It's tied to municipal finance decisions playing out in real time, some of them made in a town the buyer isn't even purchasing in.
A Few Direct Questions
Is this dispute still active? No. The New Jersey Supreme Court denied Pennington's final appeal in February 2026, and the ruling stands.
Does this change my tax bill this year? Not directly, and not all at once. The shift plays out over the remaining life of the 30-year PILOT agreement, and Pennington's council has said it intends to manage increases through its own budgeting rather than pass the full amount through in any single year.
Does the $16.1 million from PILOT revenue offset the cost? It helps. That money funds a specific building project at Bear Tavern Elementary, which benefits the whole regional district, but Pennington's own estimate is that it doesn't erase the broader $25 million shift projected over three decades.
Should this stop someone from buying in Pennington? That's a personal financial question this article can't answer for you. It's one more piece of information worth weighing before you compare a listing's current tax bill against what a similar home might cost to carry ten or twenty years from now.
