Closed for 2026 — next deadline Apr 1, 2027
Closed for 2026. The next deadline is April 1, 2027 (January 15, 2027 in Burlington, Gloucester and Monmouth counties).
Gloucester County homeowners pay a median of $8,055 a year in property tax on a median home value of $310,400. Its effective tax rate (property taxes paid as a share of home values, per the Tax Foundation) is 2.40%, the 2nd highest of 21 New Jersey counties. In New Jersey your town's tax assessor sets your assessment, and appeals go to the Gloucester County Board of Taxation. The board can lower, keep or raise the assessment after a short hearing.
The petition must be received (not just postmarked) by April 1 of the tax year, or 45 days after the town finishes the bulk mailing of assessment postcards, whichever is later. In a town with a new revaluation or reassessment the deadline is May 1. Burlington, Gloucester and Monmouth counties use an alternative calendar with a January 15 deadline. If the last day falls on a weekend or holiday, it moves to the next business day. Example: Cumberland County - April 1 (or 45 days after postcards), May 1 for revalued towns.

How to appeal in Gloucester County, step by step
Read your notice
Every owner gets an Assessment Notification Postcard in February showing the current year's assessment and explaining how and when to appeal. Towns that just finished a revaluation send new values in the revaluation year.
Check your property record
Look up your home on the Gloucester County Board of Taxation website and check square footage, bathrooms, condition and features. Mistakes are the easiest wins. Use our record card checklist.
File by the deadline
File Form A-1 (Petition of Appeal) with the Gloucester County Board of Taxation so it is received by the deadline, and send copies to your town's assessor and municipal clerk. Many counties accept appeals online.
Gather evidence
What works in New Jersey:
- 3 to 5 comparable sales of similar homes
- Photos of your home and of the comparables, especially of condition problems
- A written appraisal by a licensed appraiser
- Your property record card from the assessor
- Repair estimates, surveys or other documents showing defects or special circumstances
More detail
- 3 to 5 comparable sales of similar homes (style, size, age, neighborhood) that sold close to the October 1 valuation date, with block, lot, sale price and deed date (Form A-1 Comp. Sale)
- Photos of your home and of the comparables, especially of condition problems
- A written appraisal by a licensed appraiser - the appraiser must attend the hearing to testify, and copies must go to the board and assessor at least 7 days before
- Your property record card from the assessor (the town must give you a copy on request) to catch errors in size, rooms or condition
- Repair estimates, surveys or other documents showing defects or special circumstances
Go to the hearing
Bring copies of your evidence for each board member. Keep to the value of your home, not the size of the bill.
More detail
Your assessment is presumed correct. You must prove, with solid evidence, the true market value of your home as of October 1 of the prior year. The board then applies the Chapter 123 test: if your assessment divided by that value is more than 15% above the town's average ratio, it is lowered to the common level.
If you disagree with the decision
Next step: Tax Court of New Jersey. 45 days from the date the county board's judgment was mailed. Homes assessed over $1,000,000 can skip the county board and file directly with the Tax Court by April 1 (May 1 in revaluation towns). File a Local Property Tax Complaint, usually through the courts' eCourts system. A home (Class 2, 1-4 family) qualifies for the Small Claims track: $50 filing fee for one parcel ($10 each extra). Regular track is $250. You may represent yourself; court staff can help with forms but not give legal advice.
The official appeal form is A-1: Petition of Appeal (County Board of Taxation).
Open Form A-1How much could you save?
Enter the market value on your assessment notice and what you think the home would really sell for. We estimate the yearly saving if the board agrees with you.
Some states cap how fast the taxable value of a home can rise (California, Florida, Michigan and Texas homesteads, for example). If your taxable value is already held below market value by a cap, a lower market value may not lower this year's bill.
