General rate and effective rate in Roselle
New Jersey publishes two rates for every municipality. The general tax rate, $9.147 per $100 in Roselle, is the one applied to the assessed value on the bill: $300,000 assessed owes $27,441.00. The effective tax rate, $2.819 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's assessments at about 30.82% 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 ranks 61st of 564, against 7th on the general rate, and sits $0.680 above the $2.140 median effective rate. At 30.82%, a $300,000 assessment corresponds to roughly $973,394 of market value.

Each bill is the assessed value divided by 100 and multiplied by $9.147, before exemptions, credits or special charges. These are assessed values, not sale prices: at 30.82% the $300,000 row is a property worth about $973,394. The last column is the difference from the same assessment at the $2.960 per $100 state median.

Appealing a Roselle 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 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 30.82% ratio implied by the state's two rates, that range runs from about 26.2% to 35.44% of market value; the Director's official average ratio for Roselle, which the County Board applies, can differ slightly.
