General rate and effective rate in Roselle Park
New Jersey publishes two rates for every municipality. The general tax rate, $4.506 per $100 in Roselle Park, is the one applied to the assessed value on the bill: $300,000 assessed owes $13,518.00. The effective tax rate, $2.521 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 Roselle Park's assessments at about 55.95% of market value, well below market value, the sign of a town that has not revalued recently; the state median is 70.02%.
The effective rate is the fairer comparison between towns. On it Roselle Park ranks 119th of 564, against 74th on the general rate, and sits $0.380 above the $2.140 median effective rate. At 55.95%, a $300,000 assessment corresponds to roughly $536,193 of market value.

These are assessed values, not sale prices: at 55.95% the $300,000 row is a property worth about $536,193. The last column is the difference from the same assessment at the $2.960 per $100 state median.

Appealing a Roselle Park assessment
New Jersey appeals go to the Union County Board of Taxation. The petition is due April 1, or May 1 in a year when Roselle Park 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 55.95% ratio implied by the state's two rates, that range runs from about 47.56% to 64.34% of market value; the Director's official average ratio for Roselle Park, which the County Board applies, can differ slightly.
