Short answer: The average Montville homeowner paid $14,423 in property taxes in 2025, according to the NJ Division of Taxation, up about 2.9% from $14,018 in 2024. The 2025 general tax rate was 2.673 and the effective rate was 1.927, so a quick estimate is roughly 1.9% of a home’s market value per year.

Montville’s 2025 Tax Numbers
| Measure (2025) | Montville Township |
|---|---|
| Average residential tax bill | $14,423 |
| Average residential assessment | $539,597 |
| General tax rate (per $100 of assessed value) | 2.673 |
| Effective tax rate (per $100 of market value) | 1.927 |
| Average ratio of assessed to true value | 72.21% |
| 2024 average residential tax bill | $14,018 |
The two rates exist because Montville assesses homes below full market value. In 2025, the county equalization table put Montville’s average assessment at 72.21% of true value. The general rate applies to the assessed value printed on your tax card. The effective rate applies to market value, which makes it the easier number to use when you are looking at a list price.
How to Estimate Taxes on a Montville Home
The most accurate number is the actual tax bill on the property you are considering, which is public record. For a rough estimate based on price, multiply by the effective rate:
| Market value | Estimated annual tax at the 2025 effective rate (1.927%) |
|---|---|
| $700,000 | About $13,500 |
| $900,000 | About $17,300 |
| $1,200,000 | About $23,100 |
These are illustrations only. A specific home’s bill depends on its own assessment, which may be higher or lower than the township average ratio would suggest.
One point surprises many buyers: in New Jersey, a sale does not by itself reset a home’s assessment. Assessments change through a town-wide revaluation or reassessment, or when improvements such as an addition raise a home’s value. That is why two similar houses on the same street can carry noticeably different bills.
How Montville Compares With Nearby Towns
| Town (2025) | Average tax bill | General rate | Effective rate | Average sale price |
|---|---|---|---|---|
| Montville Twp | $14,423 | 2.673 | 1.927 | $896,959 |
| Boonton Twp | $13,463 | 2.538 | 1.967 | $847,877 |
| Kinnelon | $17,357 | 2.985 | 2.418 | $916,352 |
| Lincoln Park | $10,566 | 2.171 | 2.220 | $528,610 |
| Parsippany-Troy Hills | $10,852 | 3.452 | 2.452 | $598,767 |
| Morris County average | $12,175 | n/a | n/a | $787,973 |
Montville’s average bill is higher than the county average, but so are its home prices. Measured by effective rate, Montville is lower than Kinnelon, Lincoln Park and Parsippany-Troy Hills, which means each dollar of home value carries a little less tax there.
Where the Money Goes
A New Jersey property tax bill combines the school, municipal and county levies. On the school side, the Montville Township School District’s 2025–26 budget summary lists a general fund school tax levy of about $81.8 million, plus about $0.9 million for debt service, supporting an estimated on-roll enrollment of 3,566 students. Our guide to how NJ property taxes work in Morris County walks through each part of the bill.
Due Dates and Closing
New Jersey property taxes are paid in four quarterly installments, due February 1, May 1, August 1 and November 1. Late payments can accrue interest of up to 8% on the first $1,500 and 18% on amounts above that. When you buy, the closing attorneys or title company prorate the current quarter’s taxes between buyer and seller, and many buyers pay ongoing taxes through a mortgage escrow account.
Appealing a Montville Assessment
If you think your assessment is too high compared with market value, you can file a petition with the Morris County Board of Taxation (30 Schuyler Place, Morristown). For 2026, the deadline was April 1, or 45 days after the bulk mailing of assessment notices if later, and May 1 in towns that completed a revaluation. Properties assessed over $1 million may file directly with the Tax Court instead.
Appeals use New Jersey’s Chapter 123 test. The board compares your assessment-to-value ratio with the town’s average ratio, and if yours is more than 15% above that average, the assessment is reduced to the common level. Using Montville’s 2025 average ratio of 72.21% as an example, the range would run from about 61.4% to 83.0%. Check the current year’s Chapter 123 ratio before filing, and bring three to five recent comparable sales.
