What Is the New Milford NJ Property Tax Rate?

The New Milford, NJ property tax rate for 2025 is $2.178 per $100 of assessed value, with an effective rate of $2.261.¹ That is a steep drop from the 2024 general rate of $4.035,² but the drop reflects a borough-wide revaluation that roughly doubled assessed values, not a cut in the total taxes collected. For most homeowners, the bill looks about the same.

What the Two Rates Mean

The general rate is the number multiplied against your assessed value to produce your bill. The effective rate adjusts for the gap between assessed values and real market prices, which is why it gives a truer picture of the tax burden across the borough.

In 2024, the wide gap between $4.035 and the effective rate of $2.482 signaled that assessments sat well below market value. New Milford’s revaluation closed that gap. The 2026 Chapter 123 average ratio is 97.49%, meaning assessments now sit at roughly 97.5% of true market value.³

Here is where homeowners get tripped up. A lower rate applied to a higher assessed value usually produces a similar bill. A home previously assessed at $250,000 under the 4.035 rate paid about $10,088. If the revaluation lifted that assessment to $475,000 under the 2.178 rate, the bill is now about $10,346. The rate fell by nearly half; the bill barely moved.

How to Calculate Your Bill

Multiply your property’s assessed value by the general tax rate, then divide by 100. For a home assessed at $450,000 under the 2025 rate:

$450,000 × 2.178 ÷ 100 = $9,801 per year.

That annual figure is split into four quarterly installments of roughly $2,450. Use the assessment from your most recent notice, not the pre-revaluation number. If your mortgage includes an escrow account, the lender will recalculate your monthly payment to match the new tax amount, so expect an adjustment in a revaluation year.

Where Your Tax Dollars Go

Your single quarterly payment funds three separate entities. The borough collects the full amount and forwards shares to the school district and the county.

New Milford Public Schools take the largest share, typically around 60% of the total levy in Bergen County communities, covering teacher salaries, buildings, and instructional programs.
The Borough of New Milford funds police, fire, road maintenance, trash collection, parks, and general operations from the municipal portion.
Bergen County uses its share for the court system, county roads, public health programs, and open space preservation.

Because the school portion dominates, school budget decisions have the most direct impact on the overall rate.

If You Think Your Assessment Is Too High

The borough’s Tax Assessor sets values based on comparable sales, location, lot size, square footage, condition, and improvements.⁴ Each February, property owners receive a Chapter 75 notification card showing the current valuation. If the number looks wrong, you can file a formal appeal with the Bergen County Board of Taxation. The deadline is April 1.⁵ Miss it and you wait a full year.

Appeals are judged against the common level range, a band around the municipal average ratio. For 2026, New Milford’s range runs from 82.87% to 112.11%, with the average at 97.49%.³ If your assessment falls inside that range relative to the true market value of your home, the board is unlikely to reduce it. The strongest cases involve assessments that exceed the upper limit when measured against what the property would actually sell for.

One narrower deadline worth knowing: if the assessor issues an added assessment for a renovation or new construction completed after October 1, you have until December 1 of that tax year to appeal it, not the usual April date.

Relief Programs That Reduce What You Pay

Several New Jersey programs can meaningfully lower what New Milford homeowners actually hand over. Deadlines shift year to year, so confirm them before filing.

ANCHOR

The ANCHOR benefit pays homeowners $1,500 if household income is $150,000 or less, and $1,000 if income falls between $150,000 and $250,000. Residents 65 and older receive an additional $250 on top of those amounts. Qualifying renters get $450, with the same $250 senior add-on.⁶ Most homeowners under 65 are auto-filed by the state and receive a confirmation letter rather than needing to apply.

Stay NJ

Stay NJ reimburses seniors for 50% of their property tax bill, up to a maximum of $13,000, with a 2025 benefit cap of $6,500.⁷ You must be 65 or older, have owned and lived in your home for the full prior calendar year, and have household income below $500,000. The state began issuing first-quarter 2024 payments in February 2026, and the filing deadline for the 2025 application year is November 2, 2026.

Senior Freeze

The Senior Freeze reimburses the difference between your taxes in a base year and your current taxes, holding your effective bill at the earlier amount. You must be 65 or older, or receiving Social Security disability benefits, and income cannot exceed $172,475 for tax year 2025.⁸ You must have met the income limit in both the base year and the current year. Seniors now apply for ANCHOR, Stay NJ, and the Senior Freeze through a single combined application.

Veteran Deduction

Honorably discharged New Jersey veterans receive a $250 annual deduction from their property tax bill. Surviving spouses qualify as long as they haven’t remarried.⁹ The amount is modest, and it applies automatically once you’ve registered with the Tax Assessor’s office.

Payment Schedule and Grace Period

Property taxes are due quarterly on February 1, May 1, August 1, and November 1. The borough offers a 10-calendar-day grace period after each due date. Pay within those 10 days and no interest is charged. Pay on day 11 and interest runs retroactively to the first of the month.¹⁰

Payments go through the borough’s online portal by electronic check or credit card, by mailed paper check to the Tax Collector, or in person at Borough Hall. Credit card payments carry a convenience fee, so electronic check is the cheapest option.

What Happens If You Fall Behind

Interest accrues at 8% per year on the first $1,500 of the delinquent amount and 18% per year on anything above that.¹⁰ If your total delinquency exceeds $10,000 at the end of the calendar year, the borough can add a 6% year-end penalty on top.

New Jersey law requires every municipality to hold at least one tax lien sale per year on delinquent properties. Investors bid for the right to pay your back taxes in exchange for a lien, and they collect interest and redemption penalties when you pay it off. A certificate holder can begin foreclosure in Superior Court after two years. If the municipality itself holds the certificate, foreclosure can start after six months.¹⁰ Redemption requires paying the full back taxes, interest, and penalties in cash or certified funds; there is no installment plan. Anyone falling behind should contact the Tax Collector before a lien sale, when costs climb sharply.
