Deadline and where to file
Kenilworth values are set by the local municipal tax assessor. Your petition must be received (not just postmarked) by the county board of taxation by April 1, or 45 days after the town finishes bulk mailing assessment notices, whichever is later. If the town did a municipal-wide revaluation or reassessment, the deadline is May 1. Burlington, Gloucester and Monmouth counties use January 15 (or 45 days after notices, whichever is later).
Reading this in fall 2026? The 2026 deadlines have passed. If you live in Burlington, Gloucester or Monmouth County, the next deadline is January 15, 2027 (or 45 days after your town's notices, if later), so it is close. Everywhere else, the next deadline is April 1, 2027, or 45 days after your 2027 notice, whichever is later. If your town did a revaluation or reassessment, it is May 1, 2027. Check your notice, because the exact date depends on when the town mailed it.
