The 2026 filing window closed on May 1, 2026. The rule is April 1 (May 1 with a revaluation; January 15 in Burlington, Gloucester, and Monmouth), so the next deadline is May 1, 2027. Use the time before it opens to build the evidence.

Knowing your deadline is half of it. The other half is whether the county’s number is actually too high, because a deadline you meet with no case is just paperwork. Checking your number is free and takes about a minute.

Updated March 2026
New Jersey has two property tax appeal deadlines depending on your county. Most counties require filing by April 1, 2026, while others allow until May 1, 2026.
These counties require appeals by April 1 (32 days from today):
Only Bergen County has a standard May 1 deadline.
Special situations for May 1:
You can only choose ONE path per year.
NJ Tax Court Rule 8:4 states no deadline extensions except for:
"I didn't know" = appeal dismissed.
Knowing the date is the easy part. The date only matters if the county's number is actually too high, and nobody checks that number for you.
The number your appeal would challenge, pulled free in seconds. No account needed.
If you receive a Chapter 91 request:
Evidence comes after filing, meet deadline first.
Example:
All gone if you file April 2 instead of April 1.
A real AppealDesk order, Somerset County
In April 2026, a homeowner in Somerset County ran the check. The county had their home on record at $1,081,400, while recorded sales of comparable homes supported about $937,633: an over-assessment of $143,767, worth roughly $2,488 per year if corrected. Their packet laid out the comparable sales, the forms, and the filing steps. Nobody at the county was ever going to run that check for them.
A deadline you meet with no evidence behind it is just paperwork. Comparable sales are what boards actually respond to, and pulling your county's number is where that starts.
Enter your address to pull your county record free. If it looks too high, your $49 packet gives you the comparable sales, forms, and filing steps.
