Think Your Haddonfield Assessment Is Too High? How a Property Tax Appeal Works

If you think your Haddonfield assessment is too high, you appeal to the Camden County Board of Taxation. For 2027, the county says your appeal must arrive between Feb. 1 and 4 p.m. on Thursday, April 1. That sounds far off. It isn't, because the work is gathering evidence, and November is a fine time to start.

The one thing you have to prove

Here's the part people miss. You're not arguing that your taxes are too high. You're arguing that your assessed value is wrong compared with market value.

The New Jersey Division of Taxation says you must show the assessment doesn't fairly reflect either true market value or the town's common level range. That range is plus or minus 15% of the average ratio for your town. Translation: small gaps usually don't win. You need comparable sales that tell a clear story.

The deadlines

• Window opens: Feb. 1, 2027. The county asks you to wait for your Notice of Assessment card from the assessor, which must be mailed by Feb. 1.
• Deadline: 4 p.m. Thursday, April 1, 2027, or 45 days after the town finishes mailing assessment notices, whichever is later.
• Revaluation towns: 4 p.m. Monday, May 3, 2027.
• Received, not postmarked. Late means dismissal.

How to file

You can file online through mynjappeal.com, by mail, or in person using Form A-1, the Petition of Appeal. The county notes its online system doesn't work in Microsoft Edge. Paper filers also send copies to the Haddonfield tax assessor and the borough clerk.

One condition: you must pay first quarter taxes, due Feb. 1, plus other municipal charges. Skipping that can get your appeal tossed. If you need a refresher on paying, see our guide to Haddonfield property taxes and the grace period.

What it costs

The fees are listed on the state's Form A-1 and are nonrefundable. Make checks payable to the Camden County Tax Administrator.

Assessed value	Fee
Under $150,000	$5
$150,000 to under $500,000	$25
$500,000 to under $1 million	$100
$1 million or more	$150

There's no fee to contest a denied senior, disabled or veteran deduction. Owners assessed above $1 million can also go straight to the State Tax Court.

Your evidence

The county's advice is blunt. List comparable sales on the petition and attach them when you file. At the latest, your evidence must reach the tax board, the assessor and the clerk seven days before your hearing, by 4 p.m. Show up with it at the hearing and it won't be admitted.

Good comparables are recent sales of similar homes nearby. Make sure they're actually in the borough. Our explainer on checking whether an 08033 home is in Haddonfield helps here.

Worth doing?

Sometimes. If recent sales of homes like yours clearly came in under your assessment, an appeal can pay for itself fast. If the gap is small, the filing fee and your time may not be worth it. Start a folder now, and decide in February.
