Property Tax Appeals · New Jersey
Appeal your property taxes
in New Jersey.
New Jersey homeowners appeal to their County Board of Taxation (or directly to the Tax Court for assessments over $1 million). The state’s twist is Chapter 123: your assessment is only considered wrong if the implied market value falls outside a corridor around the county’s average assessment ratio — roughly a ±15% band. That makes the math step matter: you need to know your town’s ratio, divide your assessment by it, and show the true market value sits below the corridor. With the nation’s highest property taxes, successful New Jersey appeals pay for themselves quickly.
Generally April 1 (May 1 where a district-wide revaluation took effect). A few counties on the alternative calendar — like Monmouth — use January deadlines.
Because of the Chapter 123 corridor, a New Jersey appeal is won or lost on a credible market value number — which is why a licensed appraisal, rather than a handful of Zillow screenshots, is the standard evidence.
The evidence
Boards act on value,
not frustration.
However New Jersey labels the process, the case underneath is identical: show what your home was actually worth on the assessment date. A licensed, USPAP-compliant appraisal — comparable sales, documented adjustments, a signed opinion of value — is that showing. Start with the $5 check to see if the numbers are on your side before you spend real money.
- Valued as of your assessment date — not today
- Comparable sales with adjustments and citations
- Signed by a state-licensed NJ appraiser
- Phone walkthrough — no stranger in your home
- Delivered in 48–72 hours, rush available

April 1 in most municipalities, May 1 where a revaluation or reassessment was implemented, and earlier (mid-January) in counties on the alternative assessment calendar such as Monmouth. Your postcard notice states your deadline.
A New Jersey standard that compares your assessment to market value through the county ratio. If your implied value is more than ~15% above true value, the board must correct it — so proving true market value is the whole case.
