General rate and effective rate in Old Tappan
New Jersey publishes two rates for every municipality. The general tax rate, $2.346 per $100 in Old Tappan, is the one applied to the assessed value on the bill: $300,000 assessed owes $7,038.00. The effective tax rate, $1.785 per $100, is "the general property tax adjusted by the municipality's equalization ratio", the rate on market value. Dividing one by the other puts Old Tappan's assessments at about 76.09% of market value; the state median is 70.02%.

Appealing a Old Tappan 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 Old Tappan 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 76.09% ratio implied by the state's two rates, that range runs from about 64.68% to 87.5% of market value; the Director's official average ratio for Old Tappan, which the County Board applies, can differ slightly.
