Primary source: New Jersey Division of Taxation, Local Property Tax Statistical Information, General Tax Rates by County and Municipality. The latest statewide table currently published is 2025. View the official state statistics page.
Watchdog loads /property/tax-rates.json, the maintained municipal history contract already used by Watchdog tax tools. A municipality is included only when both its 2024 and 2025 General Tax Rates are finite. Point change equals 2025 rate minus 2024 rate. Percent change equals that point change divided by the 2024 rate. Rows are ranked by point change, then percent change.
This is not a ranking of average tax bills, effective tax burden, school spending, assessment fairness, or Watchdog Score. A falling published General Tax Rate can accompany rising assessments, and a rising rate can accompany other assessment changes. Use the underlying assessment and bill data for property-level conclusions.
