How the ratio works: New Jersey towns often assess below full market value. The average ratio (Director’s / Chapter 123) estimates what percent of true market value the town’s assessments represent. Implied equalized value ≈ assessed net ÷ (ratio ÷ 100). Example: assessed $187,600 at 55.89% ≈ $335,700 equalized. Tax bills still use assessed value × the general tax rate — not the equalized figure.
This town revalued/reassessed for tax year 2026. New assessments are set near true market value, so we treat the ratio as ~100% for this year. Published Chapter 123 average ratio for appeals/statistics is still 97.52% (often still reflecting the prior assessment base).
