General rate and effective rate in Millstone Township
New Jersey publishes two rates for every municipality. The general tax rate, $2.116 per $100 in Millstone Township, is the one applied to the assessed value on the bill: $300,000 assessed owes $6,348.00. The effective tax rate, $1.429 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 Millstone Township's assessments at about 67.53% 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 Millstone Township assessment
New Jersey appeals go to the Monmouth County Board of Taxation. Monmouth County is one of the three counties on the alternative calendar, so the petition deadline is January 15 (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 67.53% ratio implied by the state's two rates, that range runs from about 57.4% to 77.66% of market value; the Director's official average ratio for Millstone Township, which the County Board applies, can differ slightly.
