General rate and effective rate in Stillwater Township
New Jersey publishes two rates for every municipality. The general tax rate, $3.771 per $100 in Stillwater Township, is the one applied to the assessed value on the bill: $300,000 assessed owes $11,313.00. The effective tax rate, $2.265 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 Stillwater Township's assessments at about 60.06% 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 Stillwater Township ranks 224th of 564, against 128th on the general rate, and sits $0.130 above the $2.140 median effective rate. At 60.06%, a $300,000 assessment corresponds to roughly $499,500 of market value.

These are assessed values, not sale prices: at 60.06% the $300,000 row is a property worth about $499,500.

Appealing a Stillwater Township assessment
New Jersey appeals go to the Sussex County Board of Taxation. The petition is due April 1, or May 1 in a year when Stillwater Township 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 60.06% ratio implied by the state's two rates, that range runs from about 51.05% to 69.07% of market value; the Director's official average ratio for Stillwater Township, which the County Board applies, can differ slightly.
