General rate and effective rate in South Bound Brook
New Jersey publishes two rates for every municipality. The general tax rate, $4.014 per $100 in South Bound Brook, is the one applied to the assessed value on the bill: $300,000 assessed owes $12,042.00. The effective tax rate, $2.645 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 South Bound Brook's assessments at about 65.89% 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 South Bound Brook 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 South Bound Brook 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 65.89% ratio implied by the state's two rates, that range runs from about 56.01% to 75.77% of market value; the Director's official average ratio for South Bound Brook, which the County Board applies, can differ slightly.
