General rate and effective rate in Knowlton Township
New Jersey publishes two rates for every municipality. The general tax rate, $4.271 per $100 in Knowlton Township, is the one applied to the assessed value on the bill: $300,000 assessed owes $12,813.00. The effective tax rate, $2.324 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 Knowlton Township's assessments at about 54.41% of market value, well below market value, the sign of a town that has not revalued recently; the state median is 70.02%.

Appealing a Knowlton 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 Knowlton 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 54.41% ratio implied by the state's two rates, that range runs from about 46.25% to 62.57% of market value; the Director's official average ratio for Knowlton Township, which the County Board applies, can differ slightly.
