General rate and effective rate in Hillsborough Township
New Jersey publishes two rates for every municipality. The general tax rate, $2.160 per $100 in Hillsborough Township, is the one applied to the assessed value on the bill: $300,000 assessed owes $6,480.00. The effective tax rate, $2.083 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 Hillsborough Township's assessments at about 96.44% of market value; the state median is 70.02%.
The effective rate is the fairer comparison between towns. On it Hillsborough Township ranks 311th of 564, against 409th on the general rate, and sits $0.060 below the $2.140 median effective rate. At 96.44%, a $300,000 assessment corresponds to roughly $311,074 of market value.

Appealing a Hillsborough Township assessment
New Jersey appeals go to the Somerset County Board of Taxation. The petition is due April 1, or May 1 in a year when Hillsborough 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 96.44% ratio implied by the state's two rates, that range runs from about 81.97% to 110.91% of market value; the Director's official average ratio for Hillsborough Township, which the County Board applies, can differ slightly.
