Appealing a Mannington Township assessment
New Jersey appeals go to the Salem County Board of Taxation. The petition is due April 1, or May 1 in a year when Mannington Township implemented a municipal-wide revaluation or reassessment (NJ Division of Taxation). Property assessed above $1,000,000 may go directly to the Tax Court, and a County Board judgment can be appealed to the Tax Court within 45 days. The Board tests the assessment against the common level range: the average ratio plus or minus 15%. Using the 82.8% ratio implied by the state's two rates, that range runs from about 70.38% to 95.22% of market value; the Director's official average ratio for Mannington Township, which the County Board applies, can differ slightly.
