A buyer touring Belle Mead or Skillman this fall will do the math the way everyone does: take the asking price, multiply by an interest rate, add taxes, see if the number still works. It's the taxes line that stops people. Montgomery Township carries the highest average property tax bill in Somerset County, according to a New Jersey Department of Community Affairs report covering 2023 that put the average resident's payment at $17,067 a year. That figure gets repeated in listing conversations like a warning label. What rarely gets repeated is where that money actually goes, and what would have to change for it to go somewhere else.
This matters right now because Montgomery has a specific, dated answer on the table: the Montgomery Promenade, a 281,829-square-foot retail development on Route 206 anchored by Whole Foods. Township officials have framed the project explicitly as tax relief, new commercial "rateables" joining a base that's overwhelmingly residential. New loop roads tied to the project, Nevius Boulevard and Bolmer Corner, opened to the public on August 7, 2026, with Village Drive following days later. The infrastructure is real and it's moving. The question a buyer actually needs answered isn't whether the Promenade helps. It's whether it helps enough, and fast enough, to change a decision made this year.
Where the $17,067 actually goes
Break down that 2023 DCA figure and the school district accounts for $11,964 of it, county services for $2,603, and municipal government, the township services most people picture when they hear "local taxes," for just $2,500. That last number is the one worth sitting with. Montgomery's municipal government is not the reason the total bill is high. Schools are.
This isn't a Montgomery-specific quirk. New Jersey funds public education overwhelmingly through local property taxes, and a township with a young, growing student population is going to show it in the bill. Montgomery's school district serves more than 5,000 students and has been counted among the state's fastest-growing districts, which is a fact worth knowing if you're evaluating schools, and a fact that explains the tax bill better than any line item about road paving or police coverage ever will.
The township isn't the one spending
If a buyer's working theory is that Montgomery's government runs an expensive operation, the township's own 2026 budget documents don't support it. The core municipal budget for 2026, excluding grants, came in at $32,826,592, up from $31,718,666 in 2025. That's a 3.49% increase, which the township's own finance office described as below inflation. Township officials also noted there were no increases in discretionary spending for the year. The estimated 2026 municipal tax rate of 0.501 translates to an annual increase of $98.74 for the average assessed home, or about $8.23 a month.
Put plainly: municipal government accounts for 13.75% of a property owner's total tax bill, and that slice grew modestly and deliberately. The bill is high because of a funding structure that runs through Trenton and the school funding formula, not because Montgomery's town hall is over budget.
What the Promenade actually adds, against what already exists
Here's the number that puts the Promenade in proportion. Montgomery's total certified ratables for 2026 sit at $4,045,323,938. The Promenade's 281,829 square feet of retail space, even fully leased and fully taxed at commercial rates, is a new entry into a base already worth over four billion dollars. It is not nothing. It is also not the kind of addition that resets a tax bill in a single reassessment cycle.
The tenant list gives a sense of what's actually arriving: Whole Foods as the anchor, with signed leases from Shake Shack, Woof Gang Bakery, Hallmark, Panera, Ulta, and Body Rock Pilates reported in township communications. That's real commercial activity, generating real tax revenue the day the doors open. But a shopping center, however well-leased, is competing for tax-relief impact against a ratable base built overwhelmingly from single-family homes across the township's roughly 7,500 residential, farm, and commercial parcels. The math of "one retail center versus thousands of existing parcels" is why township officials themselves have talked about the Promenade in terms of easing the burden over time, not eliminating the town's ranking overnight.
How Montgomery compares to its neighbors
Somerset County's tax bills span a wide range, and Montgomery sits at the upper end of it. Public abstract of ratables data compiled at the town level for 2025 shows average bills across the county running from just under $6,000 in Bedminster Township to well over $18,000 in Watchung Borough. Montgomery's average bill lands closer to the higher end of that range, driven by the same school-funding dynamic described above rather than by unusually expensive municipal services.
| Town | What drives the number |
|---|---|
| Bedminster Township | Lower average bill, tied to a large, spread-out ratable base and fewer municipal services per parcel |
| Montgomery Township | High average bill, driven by school district costs on a young, growing student population |
| Watchung Borough | Highest average bill in the county for 2025, reflecting its own local budget and assessment mix |
The point of this table isn't to rank towns by affordability. It's to show that a high bill in Montgomery isn't an anomaly requiring explanation. It's a predictable output of how the town is built: strong schools, a growing student population, and a funding system that bills residents directly for it.
What this actually changes about how you plan
A buyer weighing Montgomery against a lower-tax neighbor should treat the Promenade as a long-horizon variable, not a near-term discount. The commercial ratables will phase in as leases finalize and the development stabilizes, and any resulting shift in the township's tax rate will show up gradually, the way infrastructure-driven tax changes usually do. Budgeting for this year's certified rate, not a rate you're hoping arrives in three years, is the more defensible approach.
It also reframes the comparison shopping many buyers do reflexively. If a nearby town shows a lower average bill, the honest next question is whether that town is funding a smaller or differently structured school district, not whether its local government is simply better run. Montgomery's own budget discipline, a 3.49% core increase against a growing tax base, suggests the township side of the ledger is already being managed conservatively. The bill is a schools story wearing a township's name.
FAQ
Will the Promenade lower my property taxes if I buy in Montgomery now? Not immediately, and not by a fixed amount anyone can promise. The development adds new commercial ratables to a base already worth over four billion dollars, which means its effect on the overall tax rate will be incremental and phased in as leases and construction finalize, not an immediate line-item reduction on next year's bill.
Is Montgomery's municipal government responsible for the high tax bill? The data doesn't support that read. Municipal government accounts for roughly 13.75% of the total bill, and the township's core budget grew 3.49% in 2026, below inflation, with no increases in discretionary spending. The bulk of the bill, over two-thirds in the most recent DCA figures, funds the school district.
How does Montgomery's tax bill compare to nearby Somerset County towns? It sits toward the higher end. County-wide averages for 2025 ranged from under $6,000 in Bedminster Township to over $18,000 in Watchung Borough, and Montgomery's average bill runs closer to the top of that range, largely a function of its school district's size and growth rather than unusual municipal spending.
Understanding what actually drives a number like this, rather than just knowing that it's high, is the difference between a buyer who reacts and one who plans. If you're comparing Montgomery to other towns and want the tax picture laid out clearly against your specific price range and timeline, Tara Stone at Stone Homes NJ can walk through the real numbers with you and help build a plan that accounts for what's actually likely to change, and what isn't, before you make an offer.
