NJ Property Tax Appeal Guide 2026
New Jersey has the highest property taxes in America. If your assessment does not reflect your home's actual market value, you may be overpaying. Here is exactly how to check, when to appeal, and how the process works.
Is Your Assessment Too High?
Your NJ property tax bill is calculated as: Assessed Value x Tax Rate = Tax Bill. The assessed value is set by your municipal tax assessor. If that assessment is higher than your home's actual market value (adjusted by the county's equalization ratio), you are paying too much.
Here is how to check: Look up your property's assessed value on your tax bill or your municipality's website. Then look at what comparable homes in your neighborhood have actually sold for recently. If your assessment implies a value significantly higher than recent sales, you have a case.
Central NJ Effective Tax Rates
For context, here is how effective tax rates vary across Central NJ. Even small differences mean thousands per year on the same home value:
| Municipality | 2025 Effective Rate | Annual Tax on $700K Home |
|---|---|---|
| Franklin Twp | 1.75% | $9,800 |
| Cranbury | 1.45% | $10,150 |
| Princeton | 1.81% | $12,670 |
| Bridgewater | 1.83% | $12,810 |
| Edison | 2.01% | $14,070 |
| Montgomery | 2.06% | $14,420 |
| Hillsborough | 2.08% | $14,560 |
| West Windsor | 2.08% | $14,560 |
| Monroe | 2.47% | $17,290 |

How to Appeal
Gather Comparable Sales
Find 3-5 recent sales (within 12 months) of similar homes in your area. Match square footage, lot size, age, condition, and location. This is the foundation of your case. We can provide a professional comparable sales analysis.
Calculate Your Ratio
Divide your assessed value by the comparable sale prices. If your ratio exceeds the county's common level range, you have strong grounds. The farther outside the range, the stronger your case.
File Form A-1
Submit Form A-1 (Petition of Appeal) to your County Board of Taxation. Deadline: April 1 in most counties (January 15 or May 1 in revaluation counties). Filing is free. Include your comparable sales data.
Attend the Hearing
Present your case at the County Tax Board hearing. Bring photos, sale data, and any property condition issues that affect value. Hearings are informal — you do not need an attorney, though one helps for complex cases.
Receive the Decision
The Board issues a decision, usually within a few weeks. If they reduce your assessment, your tax savings apply retroactively to the current tax year. If they deny, you can appeal to NJ Tax Court within 45 days.
Consider an Attorney
Tax appeal attorneys work on contingency (25-40% of first-year savings), so there is no upfront cost. They handle everything — comps, filing, hearing. Worth it for assessments over $750K or complex situations.
When a Tax Appeal Makes Sense
A tax appeal makes financial sense when:
Your assessment is 15% or more above comparable sale prices (adjusted for the equalization ratio)
You recently purchased the home for significantly less than the assessed value
Your home has condition issues (deferred maintenance, functional obsolescence, environmental issues) not reflected in the assessment
The municipality recently conducted a revaluation and your new assessment seems too high
Neighboring homes with similar characteristics have lower assessments
A tax appeal does NOT make sense when your assessment is close to market value, when you recently renovated and the assessment reflects the improvement, or when comparable sales actually support a higher value.
After a Revaluation
When your municipality conducts a revaluation (as several Central NJ towns have done recently), every property gets a new assessment based on current market values. This is actually the most important time to appeal — revaluations are done on a mass scale and individual properties are often incorrectly valued.
Common revaluation errors: incorrect square footage, wrong number of bathrooms, missing condition adjustments, failing to account for negative factors (busy road, power lines, flooding), and using incomparable sales. We frequently help homeowners identify these errors by comparing the assessor's property record card against reality.
How We Help
While we do not handle tax appeals directly (that is for a tax attorney or appraiser), we provide a critical piece of the puzzle: professional comparable sales analysis. As active agents who close dozens of transactions per year in these municipalities, we know which sales are truly comparable and how to adjust for differences in condition, upgrades, and location.
We can also refer you to experienced property tax appeal attorneys who work on contingency, meaning you pay nothing unless your taxes are reduced.
