How to appeal in Middlesex County
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.
