General rate and effective rate in West Windsor Township
New Jersey publishes two rates for every municipality. The general tax rate, $3.162 per $100 in West Windsor Township, is the one applied to the assessed value on the bill: $300,000 assessed owes $9,486.00. The effective tax rate, $2.080 per $100, is "the general property tax adjusted by the municipality's equalization ratio", the rate on market value.

Appealing a West Windsor Township assessment
New Jersey appeals go to the Mercer County Board of Taxation. The petition is due April 1, or May 1 in a year when West Windsor 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 65.78% ratio implied by the state's two rates, that range runs from about 55.91% to 75.65% of market value; the Director's official average ratio for West Windsor Township, which the County Board applies, can differ slightly.
