How Assessment Works in New Jersey
New Jersey's assessment system varies by municipality. Each municipality may assess at a different percentage of market value, and the state publishes an equalization ratio (common level range) annually. Your assessment is considered fair if it falls within the common level range for your municipality.
Risk of Increase
In New Jersey, filing a appeal can result in your assessed value being increased. This is uncommon when you have strong evidence of over-assessment, but you should be aware of this possibility. ProtestMax only recommends filing when our analysis shows a clear case for reduction.

FAQ
New Jersey Property Tax Appeal Questions
What is the common level range in New Jersey?
The common level range is a band (typically the director's ratio plus or minus 15%) that defines the acceptable assessment range. If your assessment falls within this range, it is presumed correct. To win an appeal, you need to show your assessment exceeds the upper limit of the common level range.
Can my New Jersey assessment increase on appeal?
Yes. The county Tax Board or Tax Court can increase your assessment if they find it is below the common level. However, this is uncommon in practice. File only when you have strong evidence of over-assessment.
What is a revaluation vs. reassessment in NJ?
A revaluation is a complete re-inspection and re-pricing of all properties in a municipality by an outside firm. A reassessment uses updated data without physical inspections. In revaluation years, the appeal deadline moves to January 15.
