Berkeley Heights Has One of Union County’s Lowest Effective Property Tax Rates — Here’s the Math Behind Why

Most Union County towns carry effective property tax rates above 2.0%. Berkeley Heights doesn't. The 1.820 effective rate puts it third-lowest in the county, behind only Summit and Mountainside — and the math behind it runs through a PILOT machine that's scheduled to pay down township debt until 2048.

For buyers shopping Union County in 2026, the property tax math is rarely the fun part of the conversation — but it's often the deciding one. A $1 million home in Scotch Plains carries a materially different annual tax burden than the same home in Berkeley Heights, even though the two towns sit roughly ten miles apart. The effective tax rate is what drives that gap, and Berkeley Heights' 1.820 number is an outlier for the county.

The 2026 municipal budget — formally introduced April 7, 2026 — proposes a modest 2.1% tax levy increase, amounting to roughly $57.46 annually for the average household. That's at the edge of the state-imposed cap and well below what many Union County peers are passing this year. Meanwhile, Berkeley Heights' 2026 assessment-to-sales ratio sits at 35.73%, a number that tells its own story about where the tax base is headed.

Here's the full breakdown of how Berkeley Heights achieves its lower effective rate, what the PILOT structure means for long-term tax stability, how the town compares against its neighbors, and the forward signals every buyer and homeowner should be watching.

The Headline Number

01What the 1.820 effective rate actually means for your bill

The New Jersey Division of Taxation publishes a General Tax Rates table each year showing two rates per municipality: the nominal general rate and the effective rate. The general rate is applied to the assessed value on the tax roll, which in a town like Berkeley Heights sits well below market value. The effective rate normalizes that nominal rate to what it would be if assessments equaled full market value — which is the apples-to-apples comparison a buyer actually needs.

Berkeley Heights' 2025 effective tax rate is 1.820 per $100 of true market value. Translated to dollars: a home with a true market value of $750,000 carries an all-in annual tax bill of roughly $13,650. A $1 million home is looking at approximately $18,200 a year. A $1.5 million home is around $27,300. These figures represent the combined municipal, county, and school district tax burden — the total number the homeowner actually writes checks against four times a year.

What makes 1.820 an outlier is the comparison set. The New Jersey statewide average effective rate is 2.23%. Union County as a whole runs higher than the state average. Most Berkeley Heights peers — New Providence, Scotch Plains, Cranford, Plainfield — sit in the 2.05 to 2.46 range. The only Union County towns with effective rates materially lower than Berkeley Heights are Summit (1.475), Mountainside (1.566), and, narrowly, Westfield (1.810). For a buyer comparing Midtown Direct and Gladstone Branch commuter towns, that difference compounds into real money year after year.

The Current Year

02The 2026 municipal budget: a 2.1% increase, and what it's funding

On April 7, 2026, the Berkeley Heights Township Council formally introduced the 2026 municipal budget. The headline figure was a 2.1% increase in the municipal tax levy — roughly $57.46 per year for the average household, bringing the municipal portion of the total tax bill to approximately $2,742. For context, the municipal levy is only one of three components of a New Jersey property tax bill; the other two — the Union County levy and the school district levy — are determined separately and typically make up the larger share of the total.

The 2.1% figure is significant because it sits at or near the state-imposed 2% property tax cap, but the township absorbed cost pressures on healthcare premiums, insurance, sewer operations, and debt service that in most comparable Union County towns have produced larger levy increases this year. The NW Financial presentation accompanying the budget introduction walked the council through the township's debt stack and flagged that PILOT payments from several redevelopment projects are flowing directly to debt service, reducing pressure on the conventional tax levy.

What the budget doesn't change is the effective tax rate structure. The nominal general rate will adjust marginally, but the underlying 1.820 effective rate is a function of the denominator — the total assessed value of the tax base — which doesn't move meaningfully without a revaluation. For buyers underwriting a Berkeley Heights purchase in 2026, the bill they'll see in July is a close cousin of the bill the previous owner paid in 2025, adjusted up by the levy increase and whatever changed at the county and school district level.

The Structural Subsidy

03The PILOT machine: why Berkeley Heights' debt service is running on autopilot

PILOT stands for Payment In Lieu Of Taxes. It's a state-authorized financial arrangement used extensively in New Jersey redevelopment to attract private investment to underutilized sites. Instead of a developer paying conventional property taxes under the municipal tax rate, the developer and the municipality negotiate a fixed payment schedule — typically a set dollar amount or a percentage of project gross revenue — that runs for the term of the redevelopment agreement, often 30 years.

The structural feature that matters for Berkeley Heights' effective tax rate is where those PILOT payments go. At the township's April 7 budget presentation, the financial team disclosed that PILOT payments from several older redevelopment projects are flowing directly to debt service until the year 2048. That means for the next 22 years, the carrying cost of a significant portion of Berkeley Heights' outstanding bonded debt is being covered by redevelopment payments rather than by the conventional property tax levy.

This is a mechanism most Union County towns don't have at the same scale. Scotch Plains, Cranford, Fanwood, and New Providence have redevelopment activity too, but Berkeley Heights' combination of a multi-project PILOT portfolio paired with aggressive conventional-tax new construction at Connell and The Carriages at Berkeley is distinctive. It's why the effective rate comparison isn't just a random data point — it's the measurable output of a specific long-run financial strategy.

The New Conventional Tax Base

04Connell and The Carriages: $1.7M+ in net-new school district revenue

While the older redevelopment PILOT portfolio services debt, two more recent Berkeley Heights projects are operating on a different track: they pay conventional property taxes, which flow to all three taxing jurisdictions — municipal, county, and school district. The Carriages at Berkeley Heights is expected to contribute approximately $837,000 to the Berkeley Heights school district in 2026. The Connell redevelopment is projected to contribute approximately $900,000 to the school district in 2027.

Combined, that's roughly $1.7 million per year in net-new school district revenue once both projects are fully paying into the tax roll. For a school district of Berkeley Heights' size, that's material capacity relief — funding that would otherwise have to come out of the existing residential and commercial tax base. In a county where school levies routinely outpace budget caps, adding that amount of recurring conventional tax revenue without requiring a levy increase is a structural win for existing homeowners.

The broader Berkeley Heights market context, including how the development activity is reshaping specific pockets of the township, is covered in more depth in the Berkeley Heights market trends report. For the purposes of this analysis, the tax-relevant takeaway is that newer conventional-tax construction is building a larger denominator — more properties paying into the tax base — which mechanically keeps the effective rate from climbing as fast as it otherwise would.

The Comparison

05How Berkeley Heights stacks up against its Union County neighbors

The clearest way to understand the Berkeley Heights tax advantage is to line it up against the other Union County towns a buyer might realistically be cross-shopping. The table below uses the 2025 New Jersey Division of Taxation General Tax Rates and 2026 Chapter 123 ratios, with revaluation status drawn from municipal announcements and the Union County Board of Taxation.

2025 – 2026 Tax Snapshot — Union County, NJ

Two things stand out. First: Berkeley Heights' effective rate is materially lower than the rates in the adjacent towns most Union County buyers cross-shop — New Providence, Scotch Plains, Cranford — by between 0.23 and 0.32 points. On a $1 million home, that's $2,300 to $3,200 per year in tax differential. Second: the two towns with effective rates above Berkeley Heights and comparable Chapter 123 ratios (New Providence, Scotch Plains) have both been ordered to revaluate for the 2027 tax year. That matters for the forward analysis in section 07.

The Dollar Math

06What the effective rate gap means over a 10-year hold

Buyers evaluating a Union County purchase rarely translate the effective rate difference into dollars on the page. It's worth doing, because the gap isn't trivial and it compounds. On a $750,000 home, Berkeley Heights at 1.820% carries roughly $13,650 in annual taxes. The same home in Scotch Plains at 2.137% carries roughly $16,028 — a delta of about $2,378 per year. On a $1 million home, the annual difference grows to about $3,170. Over a ten-year ownership hold, that's more than $30,000 in cumulative tax differential on the seven-figure property.

Where this math matters most is for Midtown Direct and Gladstone Branch commuters. The Berkeley Heights NJ Transit station sits on the Gladstone Branch, connecting to the Morris & Essex Lines at Summit for direct service to Newark Penn and New York Penn. NYC-based buyers evaluating a move to Union County typically narrow their short list to Summit, Chatham, Westfield, Berkeley Heights, and New Providence based on commute time. On that commuter short list, Berkeley Heights currently offers the second-lowest effective tax rate after Summit — and at a meaningfully lower entry price point than Summit's single-family market.

For homeowners considering a sale, the tax math is an underused listing asset. Listing agents in adjacent towns don't typically lead with a comparative tax analysis because in most cases it works against them. For Berkeley Heights sellers it works in their favor, and featuring it in pricing conversations and buyer packets gives the property an advantage most cross-shopped comps can't match.

The Forward Signals

07The 35.73% ratio and the reset risk on the horizon

Berkeley Heights' 2026 Chapter 123 equalization ratio is 35.73%, with a Common Level Range running from 30.37% on the low end to 41.09% on the high end. In 2025 the ratio was 41.70%. The downward movement of nearly six points in a single year reflects the fact that Berkeley Heights home values have been appreciating faster than the assessments on the tax roll — a gap that only widens as time passes without a revaluation.

That trajectory matters because of what happened to Berkeley Heights' closest ratio peer. New Providence's 2026 ratio sits at 34.32%, barely a point below Berkeley Heights, and New Providence has already been ordered by the Union County Board of Taxation to conduct a full revaluation with implementation for the 2027 tax year. The pattern is clear: when a Union County town's ratio drops into the mid-30s and stays there, a state-ordered revaluation tends to follow within a tax cycle or two.

The practical implication for buyers is straightforward: the 1.820 effective rate is real today, but it isn't permanent. A buyer underwriting a ten-year hold on a Berkeley Heights home should model at least one revaluation event within that window, with the understanding that the distributional outcome depends on how the specific property has appreciated relative to the town-wide average. Homes in the most appreciated pockets — typically the newer construction and the premium-renovated inventory near the train station — carry the most reset exposure.

For context on how Union County's other in-progress revaluations are proceeding and what homeowners in those towns are navigating right now, see the coverage of the Scotch Plains 2027 revaluation and current tax landscape. When and if the Board of Taxation orders Berkeley Heights to reset, the process will follow the same calendar — inspections, certification in January of the implementation year, and a May 1 appeal deadline.
