Property tax appeal win rates by county

This table ranks New Jersey counties using the latest 2025 appeal outcomes already maintained by Watchdog from the Division of Taxation's annual Summary of Property Tax Appeals. The ranking uses wins as a share of every appeal filed, not only cases that reached a merits decision.

Why the denominator matters. Withdrawn and dismissed cases are real filed appeals. Excluding them can make success rates look dramatically higher. Watchdog therefore uses win_rate_filed for the headline ranking and shows the underlying filing and win counts beside it.

What this ranking can and cannot tell you

It measures historical outcomes

A county's 2025 filed-appeal win rate describes what happened to that year's docket. It does not predict whether a particular property will win an appeal in 2026. Property-specific evidence, valuation date, Chapter 123 rules, filing procedure and revaluation status still matter.

Successful appeals include stipulations

The state data counts assessment reductions reached by stipulation as well as reductions ordered after a hearing. That reflects how county tax-board practice actually resolves cases instead of treating settlements as failures.

County is the published level

The Division of Taxation publishes this outcome history by county, not by municipality. Watchdog does not manufacture town-level win rates from county results. Use town reports for local assessment and equalization info, but keep appeal-outcome statistics at their published geography.

Source, method and limits

Primary source: New Jersey Division of Taxation, annual Summary of Property Tax Appeals under N.J.S.A. 54:3-5.1. Watchdog's maintained /property/appeals.json standardizes the county PDFs into a consistent 2016–2025 history.

The headline rate is wins divided by all appeals filed. A win is an assessment reduction, whether revised by the county board or stipulated by agreement. Withdrawals and dismissals remain in the filed denominator. This is intentionally different from win_rate_decided, which excludes those cases and is not used as Watchdog's headline success measure.

Total assessment reduction is the aggregate reduction in assessed value reported for successful appeals, not a homeowner cash refund and not an estimate of future tax savings. Case mix differs substantially by county and year, so the table should not be read as a league table of board quality or fairness.
