General Tax Rate vs reported tax-to-assessment rate by town
New Jersey's General Tax Rate is the multiplier used to calculate an individual property tax bill. A separate question is what tax-to-assessment relationship is actually visible across the property records in a municipality. This table puts those two checked measures side by side without pretending they are the same statistic.

Why the numbers can differ
The General Tax Rate is applied to taxable assessed value to calculate a bill. Assessment levels, revaluations, exemptions, record timing and the tax vintage present in MOD-IV can change the relationship seen when reported annual tax is divided by current assessment. That is exactly why a raw municipal rate should not be treated as a complete cross-town burden comparison.
Why this is not the State Effective Tax Rate
New Jersey describes its Effective Tax Rate as a statistical comparison measure that assumes property is assessed at 100 percent of market value. The MOD-IV measure on this page does not make that equalization adjustment. It answers a narrower question: what is the median reported tax-to-current-assessment relationship in the maintained parcel aggregate?
What this does not predict
The difference between these columns is not an appeal warning sign, revaluation forecast, fairness score or Watchdog Score component. It does not predict an individual bill. Property-level taxes still depend on the taxable assessment and the applicable General Tax Rate, subject to the official tax record.
Sources, vintage and method
General Tax Rate: NJ Division of Taxation, Local Property Tax Statistical Information. As of August 2026, the latest statewide General Tax Rates table listed by the State is tax year 2025.
Reported tax-to-assessment rate: Watchdog's maintained /property/data/statewide-intelligence.json, source ID treasury-modiv-2026. The underlying 2026 MOD-IV release currently has a blank current-year tax field, so the pipeline uses the latest positive reported annual-tax field without fabricating a 2026 tax change. The output used here is municipal aggregate data only.
Official Effective Tax Rate: the State separately publishes a General and Effective Tax Rates by County and Municipality workbook. This page links to that source but does not copy values Watchdog has not yet ingested into a checked product dataset.
