Revises procedure for determining real property tax appeal outcomes.

This bill revises how New Jersey determines the "common level range" used in real property tax appeals. It requires the Director of the Division of Taxation to certify whether adjusting this range from ±15% to ±5% of the average assessed-to-value ratio is technically feasible. If certified feasible, the reduced range (±5%) would apply to future tax appeal determinations starting with the next common level calculation. This change directly affects property owners appealing their tax assessments and county tax boards resolving those appeals, as a narrower range could make it easier for property owners to successfully challenge their tax valuations.
