Why Property Taxes Vary So Much Between Bergen County Towns (and What It Means for Your Budget)

By Darcie Hunter, SRES® | Skylands Real Estate Team, Prominent Properties Sotheby's International Realty

If you've ever compared two homes in Bergen County that were priced almost identically, only to find their tax bills were thousands of dollars apart, you're not imagining things. It's one of the most common questions I get from buyers, and honestly, from longtime homeowners too. Property taxes here can feel like a moving target, and once you understand a few basics, the differences from town to town start to make a lot more sense.

Bergen County has some of the highest property tax bills in the country, and that's not a secret. What's less understood is why a home in one town can carry a very different tax bill than a similar home just a few miles away. Let's walk through it.

It Starts With How Your Town Funds Itself

Property taxes in New Jersey are the primary way local governments pay for schools, police and fire protection, road maintenance, libraries, and other municipal services. Each of Bergen County's 70 towns sets its own budget and its own tax rate to cover those costs. A town with a larger school system or more municipal services to fund is naturally going to carry a higher rate than a smaller town with a leaner budget.

That's the first layer. The second layer, and the one that trips most people up, is how your home's value gets translated into a tax bill in the first place.

Assessed Value vs. Market Value: The Part Nobody Explains Well

Every property in New Jersey has an assessed value, which is supposed to represent a percentage of its true market value. The problem is that towns don't reassess every year, and home values shift constantly. So each municipality has what's called an equalization ratio, a number used to adjust for the gap between what a home is assessed at and what it would actually sell for today.

This is exactly why the effective tax rate is the number worth paying attention to when you're comparing towns, rather than the general tax rate alone. The effective rate accounts for the equalization ratio and gives you a much more honest, apples-to-apples comparison of what you'll actually pay relative to a home's real value.

Comparing Five Towns Side by Side

Numbers make this a lot clearer than theory, so here's how five towns I get asked about often stack up, using the 2025 rates certified by the New Jersey Division of Taxation. The general rate is what's used to calculate your actual bill against your assessed value, while the effective rate is the one that lets you compare towns fairly, since it accounts for each town's equalization ratio.

What jumps out here is that Franklin Lakes, despite being one of the higher-priced markets in this group, actually carries the lowest effective rate of the five. Mahwah lands in the middle. Oakland, Oradell, and New Milford all cluster closer together in the low-to-mid 2% range, which on paper looks similar but adds up to real monthly differences once you're comparing homes at higher price points. On a $900,000 home, for example, that gap between Franklin Lakes and New Milford works out to roughly $7,700 a year, which is worth factoring into your monthly budget just as much as your mortgage rate.

This is exactly why we encourage buyers to ask about the effective rate for any town on their list, not just the sticker price of the home or the general rate quoted in a listing. A home that looks slightly more expensive in Franklin Lakes can end up costing less per month than a "cheaper" home in a higher-rate town nearby.

What This Means While You're House Hunting

When buyers fall in love with a listing, taxes are often the last thing they check, and that's backwards. I always encourage buyers to look at the effective tax rate for any town they're seriously considering, not just the sticker price of the home. A slightly higher purchase price in a town with a lower effective rate can end up costing less per month than a "cheaper" home in a higher-rate town.

If you're relocating from out of state or coming from a lower-tax area, this is usually the biggest adjustment. It's not a reason to avoid Bergen County, it's just a number that deserves a real conversation early in your search, not a surprise at closing.

When Your Taxes Are Due

Bergen County property taxes are billed quarterly, due February 1, May 1, August 1, and November 1, with a short grace period before interest applies. If you have a mortgage, your lender is most likely collecting a portion of this annually through your escrow account and paying it on your behalf, so it's worth double-checking your escrow statements each year, especially after your town completes a reassessment.

If You Think Your Home Is Over-Assessed

Homeowners in Bergen County do have the right to appeal their assessment if they believe it doesn't reflect true market value. Appeals go through the Bergen County Board of Taxation and typically need to be filed in the spring. The strongest appeals are usually backed by solid comparable sales data, which is where working with someone who tracks the local market closely can make a real difference.

A Note for Homeowners 65 and Older

If you're a longtime homeowner thinking about your next chapter, it's worth knowing that New Jersey offers a Senior Freeze (Property Tax Reimbursement) program for income-qualified homeowners 65 and older, which can reimburse increases in your property tax bill over time. There are also exemptions available for qualifying disabled veterans. These programs won't change your decision about whether to sell or stay, but they're worth factoring into that conversation, and it's something I talk through often with clients who are weighing downsizing.
