What Happens to Property Taxes When Home Values Rise in Northern NJ?
If you’ve been watching home prices in Northern New Jersey climb, you might be wondering:
“Does this mean my property taxes are going to skyrocket?”
It’s a smart question, and one that a lot of homeowners get wrong.
Let’s break down how property taxes really work in New Jersey, what triggers reassessments and what you can do if you think your home’s value has been overstated.
How Property Taxes Are Calculated
Property taxes in New Jersey are based on a simple formula:
Assessed Value × Local Tax Rate = Annual Property Tax.
Assessed Value: What your town believes your property is worth for tax purposes.
Tax Rate: The amount per $100 of assessed value, set by your municipality, county and school district.
Even though home prices may rise quickly, your assessment doesn’t automatically change every year, unless your town conducts a revaluation or reassessment.
Revaluation vs. Reassessment — What’s the Difference?
These two terms sound similar but mean different things:
Revaluation: A town-wide update of every property’s assessed value, usually handled by an outside firm. It’s designed to bring all properties closer to true market value.
Reassessment: A smaller-scale adjustment done internally by the tax assessor, sometimes only certain neighborhoods or property types are updated.
Revaluations typically happen every 5–10 years in New Jersey, but some towns go longer (or shorter) depending on how much values have shifted.
If your town hasn’t done one in years and home prices have jumped, chances are your assessed value no longer reflects true market value and that can mean changes ahead.
Why Taxes Don’t Always Go Up When Values Rise
Here’s what most people get wrong:
When everyone’s home value goes up roughly the same amount, the local tax rate usually adjusts downward to balance the total revenue the town needs.
In other words, your taxes only go up significantly if:
Your home’s value rose more than average for your area, or
Your town increased the total tax levy (for schools, infrastructure, etc.).
So, a jump in market value doesn’t automatically equal a tax hike, but it does affect your share of the total property tax pie.
What to Expect During a Revaluation
If your town announces a revaluation:
You’ll receive a notice with your new assessed value.
The firm handling the revaluation will schedule inspections or ask for property info.
Once the process is complete, you’ll receive a letter of assessment and you’ll have a short window to appeal if you disagree.
It’s normal for homeowners to feel sticker shock when they see a big jump in value, but remember:
A higher assessment doesn’t necessarily mean higher taxes, it depends on how the tax rate changes too.
How to Appeal Your Property Tax Assessment
Here’s how to handle it strategically:
Compare recent sales of similar homes in your area (within the past year).
If your assessment is more than 15% higher than those comparable sales, you may have a strong case.
Gather evidence: MLS listings, photos, and appraisals help.
File your appeal by the annual deadline (usually April 1st in most NJ counties).
If needed, attend the hearing or hire a tax appeal attorney for representation.
✅ Pro Tip:
If your home has unique features (like a smaller lot, older roof, or no lake access compared to neighbors), note those differences clearly, they can support your appeal.
If you believe your home is over-assessed, you have the right to file a property tax appeal with your county’s Board of Taxation.
A Local Example
Let’s say two homes in Wayne are both assessed at $700,000.
After a revaluation, one rises to $700,000 because it’s lakefront with recent updates, while the other only rises to $625,000.
Even if the overall tax rate drops, the lakefront home will pay a bigger portion of the total tax levy because its share of assessed value is higher.
That’s why it’s so important to check your assessment against similar nearby homes, not just assume your taxes will move with the market.
