What actually sets New Jersey apart
New Jersey has the highest effective property tax rate in the country, and roughly half of a typical bill funds the local school district. Because municipalities are small and numerous, crossing a town line can change the bill on an identical house by several thousand dollars a year. Always price the town, not the county.

Rate and bill agree in New Jersey
New Jersey sits 1st of the fifty by tax rate and 1st by the amount a median-value owner actually pays. That agreement is less common than it sounds: 19 of the 50 states move ten places or more between the two rankings, because home values vary far more widely than rates do. In New Jersey the 2.23% headline is a fair summary rather than a figure that needs correcting.
How New Jersey works out what you owe
Each municipality assesses at its own ratio of true value, published annually as the equalization ratio, and revalues on its own schedule. There are more than five hundred separate taxing municipalities.
A 2% cap applies to the annual increase in most local government levies, with exclusions for pension, health benefit and debt service costs.
Exemptions New Jersey homeowners should claim
Each of these reduces a New Jersey bill every year you hold the property, and almost none are granted without a claim:
- Senior Freeze (Property Tax Reimbursement): Reimburses eligible owners aged 65 or older, and disabled owners, for the difference between their current bill and their bill in the base year they first qualified.
- ANCHOR and StayNJ: Statewide relief programmes that rebate a portion of property tax to homeowners within income limits, with an additional programme aimed at older residents.
Where you buy inside New Jersey changes the bill
A statewide average hides its extremes. Where they show up in New Jersey:
- Bergen County: seventy municipalities in one county, each setting its own rate, so the county average conceals enormous variation
- Essex County: contains both Newark and some of the highest-billing suburbs in the United States
- Middlesex County: a large and comparatively affordable market by New Jersey standards, with heavy school levies

- Pennsylvania at 1.35%: about $5,773 a year, roughly $3,768 less than the $9,541 a New Jersey owner would pay on the same value.

Appealing a New Jersey assessment
If the assessed value on your New Jersey home overstates what it is worth, the route is an appeal to the county Board of Taxation, then the New Jersey Tax Court. The window is appeals are due by 1 April, or 1 May in a municipality that has just revalued, and it is strict — missing it means waiting a full cycle.
Frequently asked questions
When are New Jersey property taxes due, and when must exemption claims be filed?
Bills are quarterly, due 1 February, 1 May, 1 August and 1 November. Relief programmes are administered by the New Jersey Division of Taxation with their own annual deadlines; local deductions are filed with the municipal assessor.
Does this calculator use my exact New Jersey county tax rate?
No — it applies the New Jersey statewide average of 2.23%. Rates are set locally, and the spread inside New Jersey is wide enough to matter: on a $427,600 home, $5,321 a year separates New Jersey from an averagely taxed state before any county variation is counted. Check the parcel's own rate with its New Jersey county before relying on this figure.

How this estimate is built
Principal and interest come from the standard amortization formula, worked through in full on the formula reference page. Property tax, insurance, PMI and loan-program figures layer on top from published assumptions — each one sourced, dated and listed on the methodology page. Every result here is an estimate built from public data, not a quote: confirm the specifics with a lender before relying on it.
