General rate and effective rate in Allentown
New Jersey publishes two rates for every municipality. The general tax rate, $3.547 per $100 in Allentown, is the one applied to the assessed value on the bill: $300,000 assessed owes $10,641.00. The effective tax rate, $2.360 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 Allentown's assessments at about 66.54% 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 Allentown ranks 178th of 564, against 160th on the general rate, and sits $0.220 above the $2.140 median effective rate. At 66.54%, a $300,000 assessment corresponds to roughly $450,857 of market value.

The effective rate went from $2.507 to $2.360 per $100 (down 5.86%), and the implied ratio from 77.91% to 66.54%: market values rose faster than assessments.

Each bill is the assessed value divided by 100 and multiplied by $3.547, before exemptions, credits or special charges. These are assessed values, not sale prices: at 66.54% the $300,000 row is a property worth about $450,857. The last column is the difference from the same assessment at the $2.960 per $100 state median.

Appealing a Allentown assessment
New Jersey appeals go to the Monmouth County Board of Taxation. Monmouth County is one of the three counties on the alternative calendar, so the petition deadline is January 15 (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 66.54% ratio implied by the state's two rates, that range runs from about 56.56% to 76.52% of market value; the Director's official average ratio for Allentown, which the County Board applies, can differ slightly.
