140 New Jersey towns are on the 2026 revaluation or reassessment list. Here is what homeowners should watch next

New Jersey has approved revaluations or reassessments in 140 taxing districts for 2026, according to the Division of Taxation’s official list updated May 13.

If your town is on that list, you may see a new assessed value for your home. That number matters, but it does not tell you by itself whether your property tax bill will go up.

Here is what homeowners should know.

Which South Jersey towns are on the list?

Seven taxing districts in Camden, Gloucester and Salem counties appear on the state’s 2026 list:

• Camden County: Lindenwold Borough and Pine Hill Borough.
• Gloucester County: Clayton Borough, Logan Township, West Deptford Township and Westville Borough.
• Salem County: Lower Alloways Creek Township.

The May 13 state list does not include a taxing district in Atlantic, Burlington, Cape May or Cumberland counties.

Why towns revalue property

Home values do not all move at the same pace. Over time, assessments can get out of line with current market values. A town may use a revaluation or reassessment to bring property values back in line and spread the local tax burden more fairly.

The state’s revaluation guidance explains that the process can include property inspections, measurements, building information, recent sales and other facts that affect market value.

A higher assessment does not automatically mean a higher tax bill

This is the most important part.

Imagine your home was assessed at $200,000 and the new assessment is $400,000. It is easy to look at that change and assume your taxes are about to double. That is not how a town-wide revaluation works.

When assessments across the municipality rise, the tax rate can fall. What matters more is how much your property changed compared with properties across the rest of town.

If your home increased in value faster than the town overall, you could end up carrying a larger share of the local tax burden. If it increased more slowly, your share could fall. Some homeowners may see relatively little change.

The new assessment is one part of the calculation. The municipal tax levy and resulting tax rate matter too.

What should homeowners check?

If you receive a new assessment, start with the basic information the assessor has about your property. Check the living area, property class, lot information and major improvements. A simple record error can affect value.

Then look at recent sales of reasonably similar homes in your area. Focus on actual market evidence rather than comparing your assessment with a home in another municipality.

You should also keep every assessment notice you receive. The mailing date can matter if you decide to appeal.

Pay attention to the appeal deadline

New Jersey’s normal county tax appeal deadline is generally April 1. For a municipality that has undergone a revaluation or reassessment, the deadline is generally May 1 or 45 days from the bulk mailing of assessment notices, whichever is later.

There is an important exception. Burlington, Gloucester and Monmouth counties use New Jersey’s alternative assessment calendar. The state lists January 15, or 45 days from the bulk mailing of assessment notices, as the appeal deadline under that calendar.

Deadlines are important enough that homeowners should confirm the date with their county board of taxation before filing.

Where are most of the 2026 revaluations and reassessments?

The state list is heavily concentrated in a few counties. Watchdog counted 46 districts in Monmouth County, 36 in Bergen County, 16 in Somerset County and 11 in Morris County. Together, those four counties account for 109 of the 140 districts on the May 13 list.

Other counties represented on the list include Camden, Essex, Gloucester, Hudson, Hunterdon, Middlesex, Ocean, Passaic, Salem and Sussex.

What should you do if your town is listed?

Do not panic when you see a much larger assessment. First, make sure the property information is correct. Then compare the new value with the market and pay attention to notices from your assessor.

If the value appears too high, learn the appeal process early. Waiting until a tax bill arrives can leave you with less time to understand your options.

Watchdog takeaway: A revaluation is not a list of towns getting a property tax increase. It is a change in how property values are measured. For an individual homeowner, the useful question is not simply, “Did my assessment go up?” It is, “How did my property change compared with the rest of my town?”
