New Jersey Property Tax Appeal Deadlines
The standard annual filing deadline is April 1 for most New Jersey municipalities. A May 1 deadline applies when a municipal-wide revaluation or reassessment has been implemented. Burlington, Gloucester, and Monmouth Counties use an alternative assessment calendar with a January 15 deadline. The correct deadline can change with the county, municipality, assessment type, and procedural history.

Who should review the deadline early
Owners who received a targeted NJPTC letter or a new assessment notice
Owners in a municipality that completed a revaluation or reassessment
Recent purchasers who want the sale reviewed against the assessment
Owners of income-producing property gathering rent, lease, income, expense, or appraisal records
Owners who received an added or omitted assessment, County Board judgment, inspection request, or income-and-expense request
Standard annual deadlines
April 1: Standard deadline for most regular assessment appeals.
May 1: Standard deadline when a municipal-wide revaluation or reassessment has been implemented.
January 15: Alternative assessment-calendar deadline used in Burlington, Gloucester, and Monmouth Counties.
Other deadlines may apply
Added assessments, omitted assessments, County Board judgments, Tax Court matters, appraisal reports, comparable-sale submissions, inspections, and municipal income-and-expense requests can have separate deadlines. A County Board judgment generally may be appealed to the Tax Court within 45 days of the judgment date.
Why each property must be checked
The applicable date depends on the property's county and municipality, whether a revaluation or reassessment occurred, the kind of assessment being challenged, and whether a prior judgment exists. A deadline used for another property or an earlier year may be wrong for the property under review.
What to gather before the deadline
Assessment notice, annual tax bill, and property record
Property address or block and lot
Recent purchase or settlement documents
Comparable sales and relevant market information
Property photographs and condition information
Rent, lease, occupancy, income, and expense information when relevant
Any municipal notice, inspection request, or income-and-expense request
