How to appeal your New Jersey property taxes
New Jersey homeowners file a Petition of Appeal (Form A-1) with their County Board of Taxation, typically by April 1. You must overcome a presumption of correctness with credible comparable-sales evidence. A filing fee applies based on assessed value, and properties assessed over $1 million may appeal directly to the State Tax Court.
New Jersey appeal deadline
Typically April 1 (or May 1 in a municipality that did a revaluation or reassessment).
New Jersey's standard appeal deadline is April 1, but it moves to May 1 in towns that performed a revaluation or reassessment that year, and some counties run on different calendars. Assessments over $1,000,000 may be filed directly with the State Tax Court. Confirm your date with your County Board of Taxation.
The New Jersey appeal process, step by step
1. Review your assessment postcard
By early February, your municipal assessor mails a postcard showing your assessment. New Jersey assesses against a percentage of market value, so check your town's equalization ratio to see what your assessment implies about market value.
2. File Form A-1 by the deadline (usually April 1)
File the Petition of Appeal (Form A-1) with your County Board of Taxation by April 1 — or May 1 if your town did a revaluation/reassessment. A filing fee applies, scaled to assessed value.
3. Build comparable-sales evidence
New Jersey appeals start with a presumption that the assessment is correct. You overcome it with usable comparable sales (generally arm's-length sales near the October 1 valuation date). Three to five strong comps is the standard.
4. County Board of Taxation hearing
The County Board of Taxation hears your appeal, usually in spring or summer, and issues a judgment. Present your comps and any condition issues that lower value.
5. State Tax Court (optional)
If you disagree with the county judgment, you generally have 45 days to appeal to the New Jersey Tax Court. Homes assessed over $1,000,000 may file there directly.
