How to File a Property Tax Appeal in New Jersey
A New Jersey property owner generally challenges a regular assessment by filing a petition with the County Board of Taxation by the deadline that applies to the property. A regular assessment greater than $1,000,000 may qualify for a direct Tax Court appeal. Confirm the route, form, deadline, service requirements, and filing fee before filing.

Who this guide is for
This guide is for New Jersey residential, commercial, industrial, and specialized-property owners who want to understand the general filing sequence before deciding whether to proceed.
When a No-Fee Review may be useful
A recent arm's-length sale is below the assessor's implied market value
Recent comparable sales may support a lower market value
Rental income or achievable market rent has declined
Vacancy, concessions, or operating expenses have increased
Condition, damage, deferred maintenance, access, use, or property-record information may affect value
A reassessment, revaluation, added assessment, or other assessment change requires review
Confirm the assessment and deadline
Start with the assessment notice, tax bill, property record, county, and municipality. The standard annual deadline is April 1 for most 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. Added or omitted assessments follow different rules.
Confirm where the appeal belongs
All owners may file with the County Board of Taxation. For a regular assessment greater than $1,000,000, the owner also may file directly with the New Jersey Tax Court. A direct appeal involving an added or omitted assessment uses a different threshold. A County Board judgment generally may be appealed to the Tax Court within 45 days of the judgment date.
Use the correct form and service process
The New Jersey Division of Taxation identifies Form A-1 and the comparable-sales schedule for County Board appeals. The filing instructions may require service on the County Board, municipal assessor, and municipal clerk. Follow the current official instructions for the selected filing route.
Prepare evidence of market value
The taxpayer must prove that the assessment is unreasonable under the applicable true-market-value or common-level-range standard. Evidence may include recent comparable sales, accurate property information, a qualified independent appraisal, purchase documents, condition evidence, and income and expense records for income-producing property. The evidence should relate to the October 1 assessment date for the tax year at issue.
