If you just moved to Morristown or maybe you’ve lived in Randolph for twenty years, you already know the vibe. Beautiful parks, great schools, and a property tax bill that makes you want to lie down in a dark room. Honestly, Morris County property tax is basically a local obsession. We talk about it at the diner, we complain about it at soccer games, and we definitely dread that postcard arriving in February.
But here’s the thing—most people don't actually understand how the math works. They think the town just picks a number. It’s way more chaotic than that.
Why Your Bill Isn't What You Expected
Let's get one thing straight: your tax bill isn't just one "tax." It’s a Frankenstein’s monster of three or four different budgets. You’ve got the municipal tax (your town), the school tax (the big one), the county tax, and sometimes a "special" tax for things like open space or libraries.
In 2025, the Morris County Board of County Commissioners actually held the county portion of the tax rate steady for the sixth year in a row. That’s rare. But even if the county keeps things flat, your school district might decide they need a new turf field or a HVAC overhaul. Boom. Your bill goes up anyway.
The school tax usually eats up about 50% to 60% of your total payment. It’s why towns like Mountain Lakes or the Chathams have such high bills—they’re paying for some of the best schools in the country. You're basically paying a "prestige premium" to live there.
The Weird Logic of "Assessed Value"
This is where people get tripped up. Your assessed value is not what you could sell your house for today. If you tried to sell your house in Parsippany for its 2026 assessed value, you'd probably be leaving six figures on the table.
Municipalities use something called an "equalization ratio." Since they don't revalue every house every single year (that would be a nightmare), the state looks at what houses are actually selling for versus what they are assessed at.
- Harding Township: You might see a $1.2 million home with a surprisingly "low" rate (around 1.024%), but the values are so high the bill still hits $12,000+.
- Netcong: The rate looks scary—over 3%—but because the median home price is lower (around $344,000), the actual bill is often less than what you'd pay in a "lower tax" town.
Basically, a low tax rate doesn't mean a low tax bill. It's all about that ratio.
How to Fight Back (The Appeal Process)
Most people just pay the bill and grumble. Don't be "most people." If you think your assessment is way off, you can file an appeal. But you have to be fast. The deadline is usually April 1st of the tax year.
You aren't appealing the tax dollar amount. You are appealing the assessment.
To win, you need "comps"—comparable sales. You can't just say, "My neighbor’s house is nicer and they pay less." The tax board doesn't care about your neighbor's bill. They care about what a house exactly like yours sold for before October 1st of the previous year.
If your property is assessed at over $1 million, you can actually skip the county board and go straight to the Tax Court of New Jersey. It’s a bit more formal, but for high-value estates in places like Mendham, it’s often the only way to get a fair shake.
New Relief in 2026: Stay NJ and ANCHOR
There is actually some good news for once. New Jersey is launching the Stay NJ program in 2026. This is huge for seniors (65+).
If you qualify, you could get a credit for 50% of your property tax bill, capped at $6,500. It’s designed to keep grandparents from moving to Florida just because they can't afford the taxes on a house they’ve owned since 1980. This works alongside the ANCHOR program and the Senior Freeze.

The state now uses a single application called the PAS-1 form. You fill it out, and the Treasury department is supposed to figure out which combination of programs gives you the most money back. Honestly, it’s the first time the process hasn't felt like a bureaucratic maze designed to make you give up.

Moving Forward
If you're looking at a Morris County property tax bill right now and feeling the squeeze, your first step is checking your assessment postcard in February. If that number looks significantly higher than what houses in your neighborhood are actually selling for, start gathering your sales data immediately.
Don't wait until March 30th to find a lawyer or an appraiser. By then, everyone in the county is trying to do the same thing.
Check your eligibility for the Stay NJ credits if you're over 65, and make sure your ANCHOR info is updated with the state. The money is there, but they aren't going to hunt you down to give it to you. You've got to be proactive.
Next Steps for Homeowners:
- Verify your assessment: Check the green postcard arriving in early February.
- Pull the "Comps": Look at sales in your specific neighborhood from April to October of last year.
- Apply for PAS-1: If you are a senior or disabled, get the 2026 Stay NJ application submitted during the open window to lock in that 50% credit.
