General rate and effective rate in New Providence
New Jersey publishes two rates for every municipality. The general tax rate, $5.242 per $100 in New Providence, is the one applied to the assessed value on the bill: $300,000 assessed owes $15,726.00. The effective tax rate, $2.049 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 New Providence's assessments at about 39.09% 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 New Providence ranks 328th of 564, against 46th on the general rate, and sits $0.090 below the $2.140 median effective rate. At 39.09%, a $300,000 assessment corresponds to roughly $767,460 of market value.

Each bill is the assessed value divided by 100 and multiplied by $5.242, before exemptions, credits or special charges. These are assessed values, not sale prices: at 39.09% the $300,000 row is a property worth about $767,460. The last column is the difference from the same assessment at the $2.960 per $100 state median.

Appealing a New Providence 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 New Providence 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 39.09% ratio implied by the state's two rates, that range runs from about 33.23% to 44.95% of market value; the Director's official average ratio for New Providence, which the County Board applies, can differ slightly.
