Fiedler Appraisal · Assessment appeals

Think your assessment
is too high?

An appeal runs on evidence, not opinion. We put your property's real market value in writing — and tell you honestly whether the numbers support a case at all.

How appeals actually work

The board rules on evidence.

New Jersey property taxes rest on your assessment — the town's estimate of what your property is worth. When that estimate runs meaningfully above real market value, you can petition your County Board of Taxation to correct it. What the board wants to see is credible proof of value, and the strongest proof an owner can bring is a written, independent appraisal.

Timing matters: petitions are generally due April 1 — May 1 where a district-wide revaluation took effect — and must be received by the deadline, not postmarked. There are no extensions. Start early enough for the appraisal to be done well before filing day, and confirm the current year's deadline with your county board.

We appraise residential, commercial, and farm property for appeals across all four counties — and because we also sell and auction here, we know the difference between an assessor's model and what buyers actually pay.

How it works

From doubt to documented value.

Step 01

Reality check

Tell us the property and the assessment. If an appeal looks weak on the numbers, we tell you before you spend a dollar more.

Step 02

Inspect

We inspect the property in person — condition, layout, and the details assessment models miss.

Step 03

Analyze

We develop a defensible opinion of market value from real sales in your town — the evidence a board respects.

Step 04

Report

A written report for your filing — and where counsel is involved, we work to the attorney's requirements.

Common questions

Tax appeals, answered plainly.

What is a tax appeal appraisal?

A written, independent opinion of your property’s market value, prepared by a certified appraiser to support an assessment appeal — the evidence that turns “my taxes feel too high” into a case the county board can act on.

When is the New Jersey tax appeal deadline?

Petitions to the County Board of Taxation are generally due April 1 — or May 1 in municipalities where a district-wide revaluation or reassessment took effect — and they must be received, not just postmarked, by the deadline. Confirm the current year’s date with your county board of taxation before relying on it.

Do I have a case?

It depends on whether your assessment implies a market value meaningfully above what your property would actually sell for. That is exactly the question an independent appraisal answers — and we will tell you honestly if the numbers do not support an appeal.

Where is the appeal filed?

With your County Board of Taxation (Warren, Hunterdon, Morris, or Sussex). Properties assessed over $1,000,000 may instead be filed directly with the New Jersey Tax Court — a call for your attorney.

Does an appraisal guarantee my taxes go down?

No — no honest firm will promise that. What it does is give the board credible, professional evidence of value. Without one, an appeal usually rests on the owner’s opinion, and that rarely carries the day.

We appraise; we don't give legal advice. Deadlines and procedures are set by statute and your county board — confirm the current year's rules there or with your attorney.
