Dozens of municipalities across New Jersey are undergoing reassessments or revaluations for the 2026 tax year. These updates are designed to align property assessments with current market values so that property taxes are distributed more fairly among property owners.
Some counties conduct annual reassessments as part of structured programs, while others perform updates periodically or under state orders when assessments have fallen significantly out of line with market values. If you own property in one of these municipalities, you may receive an updated Notice of Assessment reflecting a change in your property’s assessed value. Our property tax reassessment attorneys at Wolf Vespasiano can help make sure you never pay more taxes than you should.
Is Your New Jersey Commercial Property Being Reassessed for 2026?
Many New Jersey business and commercial property owners are searching to determine whether their municipality is conducting a property tax reassessment or revaluation for the 2026 tax year. Because property assessments are managed at the municipal level, reassessments do not occur statewide at the same time.
For 2026, numerous municipalities across New Jersey are updating property assessments through annual reassessment programs, municipal reassessments, or full property tax revaluations. These updates apply to all property types, including office buildings, hotels, retail spaces, warehouses, industrial facilities, apartment buildings, and other commercial real estate.

Regional Annual Updates in Gloucester and Burlington Counties
Unlike counties that operate structured annual reassessment programs, municipalities in Gloucester and Burlington Counties typically update property assessments at the local level. Individual municipalities may conduct reassessments or full property tax revaluations when assessments no longer reflect current real estate market conditions. These updates are usually scheduled by the municipality in coordination with the county tax board and the New Jersey Division of Taxation. As a result, reassessment and revaluation activity can vary significantly from town to town within each county. Gloucester County municipalities confirmed for 2026 updates include:
- Logan Township
- Clayton
- Westville
- West Deptford
Many municipalities in Burlington County also participate in accelerated or annual assessment updates as part of regional reassessment programs. Property owners should monitor notices from their municipality to determine whether their property assessment has changed for the 2026 tax year.
Individual Municipal Revaluations Ordered for 2026
Some municipalities are undergoing state-ordered revaluations for the 2026 tax year. These revaluations typically occur when property assessments have not kept pace with current market values.
Bergen County
Essex County
Middlesex County
Morris County
Ocean County
Sussex County
Property owners in Union City (Hudson County) and Paterson City (Passaic County) are also undergoing reassessments.
If your property is located in one of these municipalities, you should expect updated assessment notices reflecting revised property values. A commercial real estate tax lawyer in New Jersey can help understand what such appeals mean for your business.
Revaluation vs. Reassessment in New Jersey
New Jersey municipalities update property values using two different methods: reassessments and revaluations.
- A reassessment is completed by the municipal tax assessor.
- A revaluation is often a much costlier process completed by an outside company.
Municipalities may go years without a revaluation.
Both processes aim to ensure that property owners are taxed fairly based on current property values.
What Happens During a Tax Reassessment?
During a reassessment, municipal assessors analyze recent property sales and other market data to determine updated property values throughout the municipality.
The process typically includes several steps:
- Assessors review property sales and market conditions within the municipality.
- Data is analyzed to estimate the current market value of properties.
- Updated assessments are assigned to each property.
- Property owners receive a Notice of Assessment reflecting the new value.
The reassessment itself does not automatically increase property taxes. Instead, it redistributes the tax burden based on updated property values. If your property value increases more than others in your municipality, your tax share may rise.
Municipal Tax Reassessment Timeline in New Jersey
Property owners typically receive updated assessment notices early in the year.
In most municipalities, the timeline follows this general pattern:
- January–February: Municipalities finalize updated assessments
- February: Notices of Assessment are mailed to property owners
- April 1: Standard deadline to file a property tax appeal
- May 1: Appeal deadline for municipalities undergoing reassessment or revaluation (or 45 days from mailing of assessment notices)
Again, not all countries follow this pattern, and it may change depending on the amount of the assessment.
If you receive a notice showing a substantial increase in your property’s assessed value, you should review it promptly. An NJ tax appeal attorney from Wolf Vespasiano can help you determine if you have cause to appeal.
How Often Do NJ Municipalities Reassess Property?
New Jersey municipalities reassess property values at different intervals.
Some counties operate annual reassessment programs, which update assessments every year to keep pace with changing market conditions. Other municipalities may go several years between reassessments and then conduct a full revaluation when assessments become significantly outdated.
The state increasingly encourages municipalities to update assessments more regularly to maintain fairness in the property tax system.
Help With a Municipal Tax Reassessment Appeal
If your municipality is undergoing a reassessment or revaluation and your property assessment has increased significantly, you may have the right to file a commercial property tax appeal.
Before filing, it is important to compare your assessed value with the true market value of your property and review the applicable equalization ratios and filing deadlines. Missing the appeal deadline can prevent you from challenging your assessment for that tax year.
If you have questions about a reassessment or want help evaluating whether an appeal makes sense for your situation, contact Wolf Vespasiano to discuss your options. You can reach out through the firm’s contact form.
