Assessments are tax year 2026; latest published general rate we have is 2025. Estimate uses that rate until the 2026 rate is loaded.
Estimated tax up $13 ($279 → $292) using 2024→2025 rates (2.429 → 2.519) × assessed net.
Assessment net change: +0.9% ($11,500 → $11,600).

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.
