Deadline. Appeals to the county board of taxation must be received on or before April 1, or 45 days after the bulk mailing of the assessment notices is completed in the town, whichever is later. In a town that implemented a municipal-wide revaluation or reassessment, the deadline is May 1. A deadline on a weekend or legal holiday moves to the next business day.

Next regular deadline: Apr 1, 2027. Properties assessed over $1,000,000 may file directly with the NJ Tax Court by the same deadline.

Paper: Original Form A-1 filed with the board at 75 Bayard Street, 4th Floor. Deadline time: Must be received, not just postmarked; filings after close of business on the deadline are untimely (A-1 instructions). The board does not publish a separate cutoff time; office hours end 4:15 PM. Payment: Check payable to County Tax Administrator (per state A-1 instructions). Form: Petition of Appeal Form A-1 (linked on the board's Tax Appeal page). Filer must serve copies on the town assessor and clerk (A-1 instructions).

Filing fee by assessed value: under $150,000: $5; $150,000 to under $500,000: $25; $500,000 to under $1,000,000: $100; $1,000,000 or more: $150; classification appeal: $25. Payable to the County Tax Administrator; not refundable. Statewide fee schedule on Form A-1 (NJ Division of Taxation form dated 6-26). The Middlesex board's pages link the A-1 form; its 2026 Tax Appeal Guidelines PDF could not be opened, so no county-specific fee was verified.

The board will not hold virtual tax appeal hearings (board resolution, per its Tax Appeal page). Added/omitted assessment appeals for 2026 are due Dec 1, 2026. Prerequisite: taxes paid through Q1 (N.J.S.A. 54:3-27, A-1 instructions).
