Property Tax
Bergen County is in the middle of the most logistically complex property tax revaluation cycle in New Jersey. With 70 municipalities — more than any other county in the state — the Bergen County Board of Taxation administers an appeal calendar with five distinct 2026 deadlines depending on which town you live in. April 1 for the standard non-reval towns. April 13 for New Milford and Waldwick. May 1 for the broader reval/reassessment cohort. May 4 for a 12-municipality cluster including Paramus, Edgewater, and Lyndhurst. May 22 for Leonia and Wood-Ridge. And a December 2024 Board of Taxation recommendation has put 10 additional towns — including Hackensack, Fort Lee, Ridgewood, and Wyckoff — on the path to 2027 revaluations.
For homeowners, buyers, and sellers, this means the Bergen County tax landscape isn't a single picture. It's a mosaic of staggered timelines, different ratio environments, and different filing deadlines that reset depending on whether your municipality has been ordered, is in process, or is operating under the standard April 1 calendar. This post maps every layer — the 2026 deadline cohorts, the 2027 pipeline, the highest- and lowest-bill towns, and the practical implications for anyone transacting Bergen County real estate in the next 18 months.
Most New Jersey counties operate on a single April 1 appeal deadline (or May 1 in revaluation years). The three exception counties — Monmouth, Burlington, and Gloucester — operate on January 15. Bergen County, because of the volume of concurrent revaluations and reassessments in process across its 70 municipalities, has had to do something almost unique: stagger the May appeal cohorts across multiple specific dates so that the County Board can actually administer hearings without overwhelming its capacity.
The Bergen County Board of Taxation has confirmed five distinct 2026 deadlines based on each municipality's reval status. Filing on the wrong deadline is grounds for dismissal — the Board does not waive deadline mistakes, even when the homeowner had reasonable cause to believe their date was correct. Knowing which cohort your town belongs to is the most important single fact for any Bergen County property owner contemplating an appeal.
| Deadline | Cohort | Towns |
|---|---|---|
| April 1, 2026 | Non-Revaluation | Standard cohort — most Bergen municipalities (Tenafly, Demarest, Alpine, Englewood, Hackensack, etc.) |
| April 13, 2026 | Special | New Milford, Waldwick |
| May 1, 2026 | Reval / Reassessment | Towns that completed full revaluation or significant reassessment for 2026 |
| May 4, 2026 | Cluster A | Cresskill, Dumont, East Rutherford, Edgewater, Fairview, Hasbrouck Heights, Lyndhurst, Oradell, Palisades Park, Paramus, River Edge, Saddle Brook |
| May 22, 2026 | Cluster B | Leonia, Wood-Ridge |
Bergen County does not extend deadlines for late filers. Confirm your town's 2026 deadline directly with the Bergen County Board of Taxation (201-336-6300) before filing. Deadlines run by midnight of the listed date — late submissions are dismissed without consideration of merit.
Twelve Bergen County municipalities fall into the May 4, 2026 cluster — the largest and most consequential of the staggered deadline groups. These towns have either completed a revaluation or implemented a reassessment for the 2026 tax year, and the May 4 deadline reflects the additional time the Board provides for property owners to review new assessments before the formal appeal window closes.
Each of these 12 towns has been through some form of assessment update for the 2026 tax year. Property owners in these municipalities should have received notification of new assessed values in the weeks preceding the filing window. The May 4 deadline gives roughly 30 to 45 days from receipt of the new assessment to file a formal appeal — tighter than the standard May 1 reval deadline because of the staggered scheduling.
Leonia and Wood-Ridge sit in their own May 22 cluster, reflecting more recent or distinct assessment work. The 22-day extension beyond the broader May 1 reval cohort gives those two municipalities' property owners additional time before the deadline closes.
In December 2024, the Bergen County Board of Taxation formally recommended 10 additional municipalities for revaluations targeting the 2027 tax year. The recommendation was presented to the Bergen County Commissioners, and if approved, fieldwork would begin in 2026 with new assessments taking effect for tax year 2027. Each of the 10 towns has been monitored for several years; the formal recommendation reflects Director's Ratio drift sufficient to require correction.
| Municipality | Pre-Reval Ratio | Profile |
|---|---|---|
| Wyckoff | 84.39% | Premium northwest residential — closest to compliance |
| Hackensack | 80.69% | County seat — substantial commercial and residential mix |
| River Vale | 79.89% | Pascack Valley — premium residential with country club community |
| Montvale | 78.13% | Northern Bergen — mixed residential, corporate (Mercedes-Benz) |
| Rutherford | 72.40% | South Bergen — established borough, NYC commuter draw |
| Hillsdale | 69.26% | Pascack Valley — premium residential with school bond impact |
| Wood-Ridge | 69.10% | Wesmont development driving recent valuation surge |
| Fort Lee | 67.44% | High-rise condo concentration — significant Korean-American community |
| Ridgewood | 67.39% | Premier Bergen residential — village downtown, historic homes |
| Midland Park | 64.78% | Smallest of the 10 — compact residential borough |
Two of these 10 towns deserve specific attention because of their economic profile and the magnitude of the post-reval shift likely to follow.
Ridgewood is one of the most-searched Bergen County markets among NYC-exit buyers and consistently produces premium home values. A pre-reval ratio of 67.39% means current assessments significantly understate market value — homes are typically selling in the $1 million-plus range while assessments lag behind. The 2027 reval will produce material assessment increases for properties that have appreciated faster than the village average, including the historic East Side homes and recently-renovated Heights inventory. For Ridgewood owners considering an appeal under the current ratio environment, the 2026 filing window is the last opportunity to operate under Chapter 123's pre-reval common level range.
Fort Lee's reval is structurally distinct because of the borough's high-rise condominium concentration. Many Fort Lee condos in the buildings along Hudson Terrace and Bridge Plaza are in older inventory with assessments set at the time of original certification, while market values for renovated, larger, and higher-floor units have appreciated significantly. The 2027 reval will redistribute the borough's tax burden meaningfully — newer construction and high-floor units will likely see substantial assessment increases, while older inventory may see relatively flat outcomes.
Bergen County contains some of the highest-tax-bill municipalities in New Jersey. The premium tier — concentrated along the Northern Valley and the Hudson River bluff — produces average annual tax bills above $20,000, putting these municipalities in the top 25 statewide. The math reflects a combination of premium home values, high-quality school systems, and limited commercial tax base.
Demarest, Tenafly, Cresskill, Closter, Alpine, and the surrounding Northern Valley villages share a common profile: small populations, premium residential housing stock, top-tier school systems, and almost no commercial tax base. The result is property tax bills concentrated almost entirely on residential homeowners. The premium-market appeal economics that apply in Summit, Westfield, and Millburn apply equally — and often more — to these Bergen markets. A 10 percent assessment reduction on a Demarest home assessed at $1.5 million produces approximately $2,500 to $3,000 in annual savings, and the Freeze Act locks that in for three years.
For premium-market homeowners in these Bergen communities, the appeal strategy is identical to what works in Essex and Union County premium markets. Direct Tax Court filing becomes available for assessments above $1 million, and contingency-fee attorney representation typically pays for itself in absolute dollars. For the complete premium-market playbook including Tax Court filing strategy, contingency-fee math, and SALT cap considerations, see our premium-market NJ tax appeal guide.
Alpine specifically deserves attention. With consistently high average tax bills and median home values that have routinely cracked $4 to $5 million for premier estates along the Palisades, Alpine produces the largest absolute-dollar appeal stakes in Bergen County. A modest 8 percent assessment reduction on a $4 million Alpine home equates to approximately $7,200 in annual savings — and the same reduction extended through the Freeze Act window approaches $22,000 in absolute value. Almost every Alpine homeowner with a meaningful market-to-assessment gap should be evaluating the appeal calculus annually.
At the opposite end of the spectrum, Bergen County contains New Jersey's single lowest-tax-bill municipality. Teterboro recorded an average residential tax bill of $1,937 in 2024 — the lowest in the entire state. The reason is structural: Teterboro is a 1.1-square-mile borough dominated by Teterboro Airport and surrounding industrial and corporate infrastructure. The borough has fewer than 100 residential properties. The commercial and industrial tax base — primarily airport operations, aviation services, warehousing, and corporate office — generates massive revenue against an extraordinarily small residential count, producing an artificially low residential tax bill that has nothing to do with the borough's actual cost of governance.
Teterboro is unique. East Rutherford ($7,787 average bill) and Carlstadt ($8,763) follow as Bergen's next lowest, both reflecting similar but less extreme commercial-base subsidization of residential homeowners. These three South Bergen boroughs are the closest thing in New Jersey to commercial-driven tax relief for residential property owners — but the dynamics are not replicable elsewhere, and home buyers attracted by the low tax bills should understand that future commercial development changes (or losses) could shift the math.
For anyone transacting Bergen County real estate in 2026, the layered reval pipeline produces specific decision implications that don't apply uniformly across the county. Bergen is not one market. It's 70 markets at different points in their assessment cycles, and the right strategy depends on which cohort the property falls into.

The Bergen County Board of Taxation publishes its full revaluation/reassessment list each year. Property owners who don't know their cohort can confirm directly with the Board (201-336-6300) or check the published list on the Board's website. The mechanics of filing differ slightly across cohorts — the May 4 and May 22 clusters use specific scheduling — but the substantive evidence rules are consistent across all five Bergen deadlines.
It depends on which Bergen County municipality your property is in. The Bergen County Board of Taxation has confirmed five distinct 2026 deadlines: April 1 for non-revaluation towns (the standard cohort, including Tenafly, Demarest, Alpine, and most Bergen municipalities), April 13 for New Milford and Waldwick, May 1 for revaluation/reassessment towns, May 4 for a 12-municipality cluster (Cresskill, Dumont, East Rutherford, Edgewater, Fairview, Hasbrouck Heights, Lyndhurst, Oradell, Palisades Park, Paramus, River Edge, and Saddle Brook), and May 22 for Leonia and Wood-Ridge. Confirm your specific deadline directly with the Bergen County Board of Taxation at 201-336-6300 before filing.
In December 2024, the Bergen County Board of Taxation formally recommended 10 municipalities for revaluations targeting the 2027 tax year: Hillsdale, Montvale, River Vale, Fort Lee, Hackensack, Midland Park, Ridgewood, Rutherford, Wood-Ridge, and Wyckoff. Each carries a Director's Ratio in the 64–84% range, meaning current assessments understate true market value to varying degrees. If approved by the Bergen County Commissioners, fieldwork would begin in 2026 with new assessments effective for the 2027 tax year. Property owners in these municipalities should expect inspection notices and assessment letters during the implementation period.
Demarest had the highest 2024 average residential tax bill in Bergen County at $24,741, followed by Tenafly at $23,837, Alpine at $22,596, Saddle River at approximately $22,400, and Franklin Lakes at approximately $21,000. These five Northern Valley and northern Bergen municipalities consistently rank among the highest-tax-bill towns in all of New Jersey. The math reflects premium home values, top-tier school systems with limited state aid (under NJ's school funding formula), and limited commercial tax base spreading the levy.
Teterboro is structurally unique. The borough is a 1.1-square-mile municipality dominated by Teterboro Airport and surrounding aviation, industrial, and corporate infrastructure, with fewer than 100 residential properties total. The commercial and industrial tax base — airport operations, aviation services, warehousing, corporate offices — generates substantial revenue against an extraordinarily small residential count, producing an artificially low average residential tax bill of $1,937 (the lowest in all of New Jersey). The math is not replicable in conventional residential municipalities. East Rutherford and Carlstadt follow with similar but less extreme dynamics due to their commercial bases.
