When is the New Jersey property tax appeal deadline?

When is the New Jersey property tax appeal deadline?

In most New Jersey counties the appeal must be filed with and received by the County Board of Taxation on or before April 1 (May 1 in a revaluation/reassessment year); Burlington, Gloucester, and Monmouth Counties use a January 15 deadline.

New Jersey ties the appeal deadline to the calendar, not to when your notice arrives. Under N.J.S.A. 54:3-21, a taxpayer may appeal an assessment by filing a petition with the County Board of Taxation on or before April 1 of the tax year, or 45 days from the date the bulk mailing of the Notification of Assessment is completed, whichever is later.

The filing must be received, not just postmarked, by the deadline. The NJ Division of Taxation is explicit: "Petitions to either the County Board of Taxation or the State Tax Court must be filed and received on or before April 1st." A late filing is dismissed for lack of jurisdiction with very narrow exceptions.

Revaluation/reassessment years move the date to May 1. "Where a municipal revaluation or reassessment has been undertaken, petitions must be filed and received by May 1st" (NJ Division of Taxation).

Three counties run an earlier calendar. Burlington, Gloucester, and Monmouth Counties follow an alternate assessment calendar with a January 15 filing deadline because they participate in the annual-reassessment program.

High-value properties have a direct-to-Tax-Court option. If the assessed value of the property exceeds $1,000,000, the owner may file a complaint directly with the Tax Court of New Jersey by the same April 1 deadline instead of going to the County Board (N.J.S.A. 54:3-21).

Because New Jersey has the highest effective property tax rates in the country, a missed deadline costs an entire tax year. Confirm your county's calendar before assuming April 1.
