2026 Property Tax Appeals – A Primer for Jersey City As Ratio Sinks to 72.82%

Reminder: Civic Parent is for general teaching and educational purposes. Nothing on Civic Parent should be considered tax, accounting, or legal advice. Always consult a professional and come to agreed-upon terms if you need help with your specific facts and circumstances. With property tax appeals in particular, attorneys and real estate agents are licensed professionals who can help you with this process. Read my full disclaimer here.

It’s approaching April 1st, the property tax appeals deadline for many towns and cities in NJ including Jersey City. I have put together a quick list of resources in case it’s helpful for those who may have done this before but need a refresher or if you’re new to the process entirely.

Official Guidance – Start Here

The Hudson County Tax Appeals landing page is online here. And, the Hudson County Tax Appeals Packet is the official guidance.  I also found this Guide to Tax Appeal Hearings from NJ which aims to be more of an explainer. There is a lot of tax jargon throughout these documents which is why I have the explainers in this post (below).

Why bother? Is it worth it?

This is real money on the table if you are over-assessed. So it’s worth exploring – pressure-testing – if you are 0ver-assessed.

The way our system of local property taxation works, we can slide into – and persistently be – overtaxed without even realizing it.  In my experience (writing this blog, talking with others about this, seeing the process play out), self-advocacy is essential to ensuring you are not over-assessed (and by extention, -taxed.

I first learned about appeals in 2017 in helping Jersey City Together with a tax appeals workshop. I then wrote about appeals (articles are here) and the 2018 revaluation in Jersey City (links here) and learned more. Then in 2023 I co-hosted a free property tax appeals workshop at Saint Peter’s University with Cynthia Hadjiyannis, a local Jersey City resident and real estate attorney.

Upon reflecting on this learning journey, I can share it’s confusing and onerous and it can feel intimidating. But I continue writing about this in part because it can save taxpayers real money but also it can be an entryway into engaging the system and growing empowered with self-advocacy. The process is clear and routine and an opportunity to engage local government in a positive and proactive manner.

I’ve got some basic FAQs followed by nuance in case it’s helpful.

FAQs

What is a property tax appeal?

It is when you appeal to the County Tax Board to lower the assessed value of your home. By lowering your assessed value you can in turn lower your property tax expense (which is computed as Assessed Value x Tax Rate).

What is the basis for an appeal?

The starting premise is that your home’s assessed value should be in synch with its market value.

However, over time, the assessed value can grow out of date (“stale”) as compared to the market value. This can occur especially in communities with rapidly changing market values (like Jersey City).

When this happens, your assessed value as a measure of fair taxation for your home can get distorted. A tax appeal is the mechanism to fix the distortion.

The distortion itself is hidden behind some admittedly confusing tax math called “Chapter 123 Law” which I refer to below under “Wonk Nuance” if you are interested.

How do I actually save money through appeal?

If your assessment is lowered, then your property tax should go down, too. Let’s view this with very basic numbers; this is deliberately very simple to illustrate the tax math:

• If the tax rate is 5% and your home’s assessed value is $100, then your property tax will be $5 ($100 x 5% – $5).
• However if you lower your home’s assessed value to $60, then your property tax will decrease to $3 ($60 x 5% = $3).

It’s the base of taxation – the assessed value of your home – that you’re seeking to lower. That in turn can lower your property tax expense. This value is what is on record with local government; this is why you must undergo a formal bureaucratic process outlined in the Tax Appeals Handbook to lower the value.

I’m sharing more details below in case it’s helpful context and support for taxpayers who may need it.

Upfront Context: you can “slide into overtaxation”

This context is important so that you know the importance of self-advocacy. Here’s the basic idea:

• • Your assessed value is a “point in time” value for the tax rolls. For many of us in Jersey City, it’s based on the 2018 revaluation because that was the last time the city performed a positive inspection of all the properties and updated the tax values for their records. This is kind of like a store going through an inventory stock count and literally accounting for the value on its shelves.
  • Then your value sits there – on the metaphorical shelf – while market values continue to change (go up or down).
  • How your assessed value (stagnant, sitting on the shelf) compares to its market value (always moving) — and then also how that dynamic compares to the tax base’s assessed-vs-market value — is what the tax math aims to capture and manage.

I have a post from 2023 with an interactive teaching visual that aims to explain it – check that here: Data Visualization of “Chapter 123” Law. 

Jersey City’s 2026 “Common Level Range”

Every year the tax base is measured: both the assessed and market values. This creates a citywide “ratio” of “assessed-to-market” that exists in parallel to your home’s ratio referenced above.  These ratios are published each year as the “Common Level Ranges” for each county.

In Jersey City, in 2026, the Common Level Range data is published online here. The data is also copied/pasted below for ease of reference. It tells us that the assessed value of the tax base is 72.82% of the market value of the tax base. That is the “Average Ratio” in the table below (this is also called the “Equalization Ratio”).

What’s the process and related tax math, in a nutshell?

The Hudson County Tax Appeals Packet and NJ Guide to Tax Appeal Hearings explain it, but here’s a quick punch list:

1. Obtain your assessed value (this is on your tax postcard or you can look it up in the local database – typically hosted by your County – that lists assessed values. Reminder: tax data is public data. Hudson County’s database is here.
2. Obtain your market value; this can be estimated using evidence like recent, comparable, usable sales. “Usable” must be arms-length sales. This is strictly evidence-based and it’s explained on page 3 of the Tax Appeals Packet referenced above.
3. Divide your assessed value by your market value. That is your “ratio.“
4. Compare your home’s ratio to the 2026 “Common Level Range” (above).
5. If your ratio is above the Upper Limit then you may have a case for appeal.

Ratios to Gauge Tax Fairness

Similar to the citywide ratio (noted above), there is also a metric called the Coefficient of Deviation. You can find the NJ coefficients as of Jan 2026 online here. In 2026, these measures are pointing, directionally, to a need for the city to update its tax assessed values. In this open letter to the City Council from 2020, I shared about the the ratio and coefficient as annual, public metrics that act as annual gauges on tax fairness (sort of like a thermometer can tell you if your body heat is at or above 98.6 degrees).  Rather than re-explain that nuance, I’ll point you to the 2020 letter here for further reading.
