General rate and effective rate in Harmony Township
New Jersey publishes two rates for every municipality. The general tax rate, $2.665 per $100 in Harmony Township, is the one applied to the assessed value on the bill: $300,000 assessed owes $7,995.00. The effective tax rate, $1.592 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 Harmony Township's assessments at about 59.74% of market value, well below market value, the sign of a town that has not revalued recently; the state median is 70.02%.
The effective rate is the fairer comparison between towns. On it Harmony Township ranks 459th of 564, against 326th on the general rate, and sits $0.550 below the $2.140 median effective rate. At 59.74%, a $300,000 assessment corresponds to roughly $502,176 of market value.

Appealing a Harmony 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 Harmony 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 59.74% ratio implied by the state's two rates, that range runs from about 50.78% to 68.7% of market value; the Director's official average ratio for Harmony Township, which the County Board applies, can differ slightly.
