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 $959 ($12,856 → $13,815) using 2024→2025 rates (3.288 → 3.407) × assessed net.
Assessment net change: +3.7% ($391,000 → $405,500).

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.
