New Jersey Property Tax Appeal Guide

What This Data Tells Us About Appeals in New Jersey

In New Jersey, property tax appeals are filed with the County Tax Board / New Jersey Tax Court. The typical window is April 1 deadline for County Tax Board; May 1 for Tax Court, with the deadline most commonly falling in April. Filing fees reported for this state are $25–$150 (County Tax Board); $25 for Tax Court small claims, and Lincoln Institute research plus state-reported data suggest roughly 56% of appeals result in some reduction when supported by comparable sales or documented errors.

New Jersey has some of the highest property taxes in the nation. Appeal success rates are higher here because assessments often lag market changes. An independent appraisal ($500–$800) significantly strengthens your case. Appeals are driven by the gap between a parcel's assessed value and its actual market value — the calculator below turns that gap into an annualized dollar figure at your effective tax rate. The strongest evidence is three to five arms-length comparable sales from the past six to twelve months, plus documentation of any factual errors in the assessor's record (square footage, bedroom count, finished-basement status).

Always verify the current rules with your local assessor's office — or a licensed attorney or tax professional — before filing. Source: New Jersey Division of Taxation.
