New Jersey has the highest effective property tax rate in the United States — often 2–3% of market value. If you own property here, appealing your assessment isn’t optional. This guide walks you through exactly how to do it.
How New Jersey Property Taxes Work
Each municipality has its own assessor who values properties annually as of October 1 of the prior year. The key concept in NJ appeals is the Chapter 123 common level range — each year the Division of Taxation publishes acceptable assessment ratios for every municipality. If your assessment falls outside this range compared to what similar homes sold for, the court must adjust it.
The Deadline: April 1
New Jersey’s appeal deadline is April 1 of the tax year, or 45 days after assessment notices are mailed — whichever is later. Missing this date means waiting a full year. Set a February reminder to start gathering evidence.
The Appeal Process Step by Step
Step 1: Pull Comparable Sales
Find 3–5 similar homes in your municipality that sold within the past year at prices supporting a lower value. Use your local assessor’s public records, Zillow, or Redfin.
Step 2: File with Your County Board of Taxation
File a Petition of Appeal with your County Board of Taxation before April 1. Filing fees range from $0–$150. Include your comparable sales evidence. Most counties accept mail or in-person filings; some accept online.
Step 3: Informal Conference with the Assessor
Before your formal hearing you’ll get an informal conference with the municipal assessor. Many appeals are settled here if your evidence is strong. Come prepared with printed comps and a clear argument for your target value.
Step 4: Board of Taxation Hearing
If the informal conference doesn’t resolve it, you appear before the Board of Taxation. Present your comps, any licensed appraisal, and your argument. The board issues a written judgment within weeks.
Step 5: Tax Court (If Needed)
Properties assessed over $1 million can skip the county board and go directly to NJ Tax Court. For any property, if you’re unsatisfied with the board’s decision, you can appeal to Tax Court within 45 days. This step typically requires a licensed appraiser.
