Appealing a Frelinghuysen Township assessment
New Jersey appeals go to the Warren County Board of Taxation. The petition is due April 1, or May 1 in a year when Frelinghuysen 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 77.05% ratio implied by the state's two rates, that range runs from about 65.49% to 88.61% of market value; the Director's official average ratio for Frelinghuysen Township, which the County Board applies, can differ slightly.
