General rate and effective rate in Lambertville
New Jersey publishes two rates for every municipality. The general tax rate, $2.126 per $100 in Lambertville, is the one applied to the assessed value on the bill: $300,000 assessed owes $6,378.00. The effective tax rate, $1.902 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 Lambertville's assessments at about 89.46% of market value; the state median is 70.02%.
The effective rate is the fairer comparison between towns. On it Lambertville ranks 388th of 564, against 418th on the general rate, and sits $0.240 below the $2.140 median effective rate. At 89.46%, a $300,000 assessment corresponds to roughly $335,345 of market value.

Appealing a Lambertville assessment
New Jersey appeals go to the Hunterdon County Board of Taxation. The petition is due April 1, or May 1 in a year when Lambertville 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 89.46% ratio implied by the state's two rates, that range runs from about 76.04% to 102.88% of market value; the Director's official average ratio for Lambertville, which the County Board applies, can differ slightly.
