By the State’s numbers
Old Tappan in the Division of Taxation’s tables.
What the State publishes about residential property tax in Old Tappan, taken from the New Jersey Division of Taxation’s own tables for tax year 2025 and its 2026 assessment list. Averages describe the municipality, not any one home; a given property’s bill is its own assessment times the rate.
| General tax rate, 2025 | 2.346 per $100 of assessed value |
|---|---|
| Effective tax rate, 2025 | 1.785 |
| Average residential assessment, 2025 | $825,978 |
| Average residential tax bill, 2025 | $19,377 |
| Residential sales tabulated, 2025 | 55 · average price $1,314,730 |
| Residential line items, 2025 | 2,057 |
| Average residential assessment, 2026 list | $1,274,897 · on the 2026 approved revaluation and reassessment list |
Figures as published by the New Jersey Division of Taxation: 2025 General Tax Rates by County and Municipality, 2025 Average Residential Statistics and 2026 Average Residential Statistics, read 13 September 2026. In the Division’s own definitions, the general tax rate is the multiplier used to determine the tax levied on each property, expressed as $1 per $100 of taxable assessed value, and is the rate a bill is computed from; the effective tax rate is a statistical comparison of one district with another on the assumption that all are assessed at full value, and is not to be used to compute a bill. The sales row counts the residential sales the Division tabulated for the year and their average price, which is not a median and not a market report. Old Tappan is on the Division’s 2026 approved revaluation and reassessment list, so the 2026 figure is a new assessment base; the 2025 rate is struck against the 2025 base and does not apply to it. The same figures for all fifteen town pages are published as data at /data/town-tax.json.
