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 90.80% (often still reflecting the prior assessment base).

Assessed value & ratio history
Parcel assessed nets come from MOD-IV year files (2023, 2024, 2025, 2026). Town average ratios are from Abstract / Chapter 123 when available — implied equalized = assessed ÷ (ratio ÷ 100).
| Tax year | Assessed net | Avg ratio | Implied equalized | Assessed Δ | Equalized Δ |
|---|---|---|---|---|---|
| 2023 | $663,300 | 88.01% | $753,664 | — | — |
| 2024 | $739,300 | 100.00% | $739,300 | +11.5% | -1.9% |
| 2025 | $821,100 | 94.22% | $871,471 | +11.1% | +17.9% |
| 2026 | $911,800 | 100.00% | $911,800 | +11.0% | +4.6% |
2024: Published average ratio exceeded 100%; New Jersey treats that as 100% for equalization.
2026: 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 90.80% (often still reflecting the prior assessment base).
