General rate and effective rate in Mahwah Township
New Jersey publishes two rates for every municipality. The general tax rate, $2.127 per $100 in Mahwah Township, is the one applied to the assessed value on the bill: $300,000 assessed owes $6,381.00. The effective tax rate, $1.563 per $100, is "the general property tax adjusted by the municipality's equalization ratio", the rate on market value.

Appealing a Mahwah Township assessment
New Jersey appeals go to the Bergen County Board of Taxation. The petition is due April 1, or May 1 in a year when Mahwah 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 73.48% ratio implied by the state's two rates, that range runs from about 62.46% to 84.5% of market value; the Director's official average ratio for Mahwah Township, which the County Board applies, can differ slightly.
