Appealing a Mantua Township assessment
New Jersey appeals go to the Gloucester County Board of Taxation. Gloucester County is one of the three counties on the alternative calendar, so the petition deadline is January 15 (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 90.9% ratio implied by the state's two rates, that range runs from about 77.27% to 104.54% of market value; the Director's official average ratio for Mantua Township, which the County Board applies, can differ slightly.
