General rate and effective rate in Sea Isle City
New Jersey publishes two rates for every municipality. The general tax rate, $0.905 per $100 in Sea Isle City, is the one applied to the assessed value on the bill: $300,000 assessed owes $2,715.00. The effective tax rate, $0.453 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 Sea Isle City's assessments at about 50.06% 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 Sea Isle City ranks 557th of 564, against 549th on the general rate, and sits $1.690 below the $2.140 median effective rate. At 50.06%, a $300,000 assessment corresponds to roughly $599,281 of market value.

Appealing a Sea Isle City assessment
New Jersey appeals go to the Cape May County Board of Taxation. The petition is due April 1, or May 1 in a year when Sea Isle City 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 50.06% ratio implied by the state's two rates, that range runs from about 42.55% to 57.57% of market value; the Director's official average ratio for Sea Isle City, which the County Board applies, can differ slightly.
