Your property tax bill is based on your municipality's assessed value for your home, multiplied by the local tax rate. If that assessed value is meaningfully higher than what your home would actually sell for today, you may be overpaying — and New Jersey gives homeowners the right to appeal.
A rough gut-check
Look up your home's current assessed value on your township's tax records, then compare it honestly to what similar homes on your street or in your neighborhood have actually sold for recently. If your assessment is well above that range, it's worth a closer look.
Why "well above" and not "any difference"
Assessments and appeals both take time and, often, a fee. A small gap may not be worth pursuing. A large one — particularly if your home has issues that reduce its value but weren't reflected in the last assessment — usually is.
What actually wins an appeal
Appeals boards respond to independent evidence, not frustration. An appraisal performed by a licensed, independent appraiser — not the homeowner's own research, and not a CMA from an agent with a listing to win — is typically the strongest evidence a homeowner can bring.
Mind the deadline
Appeal deadlines vary by New Jersey county and change from year to year. Confirm the current filing deadline with your county tax board before you start.
