How assessments work in Gloucester County
New Jersey assessors set each property's value as of October 1 for the following tax year, and the county board of taxation hears appeals of those values. Burlington, Gloucester and Monmouth counties follow an alternate assessment calendar: the assessor mails a notice of assessment (the "Chapter 75 postcard") in November, and the appeal deadline is January 15 of the tax year instead of the April 1 date used in the rest of the state.
The State Division of Taxation says you must prove your assessed value is unreasonable against a market value standard. For an assessment to count as excessive or discriminatory, it has to fail both the True Market Value Standard and the Common Level Range Standard. The common level range for a taxing district is plus or minus 15 percent of the district's average ratio of assessed value to market value. Evidence of what comparable homes sold for is what moves a board. Gloucester County's Board of Taxation also acts as assessor on its own initiative, ascertains the level of assessments in each district and hears taxpayer appeals as a quasi-judicial board. Adjustments are made by written memorandum of judgment.
Exemptions and their deadlines
New Jersey runs its main homeowner relief through the State, with separate deadlines from your appeal:
- ANCHOR: the State filed for most eligible homeowners under 65 and sent confirmation letters on August 10, 2026. Seniors and homeowners collecting Social Security or Railroad Retirement disability benefits file the combined application (Form PAS-1) themselves. The deadline for the 2025 application is November 2, 2026.
- Senior Freeze (Property Tax Reimbursement): reimburses eligible seniors and disabled persons for property tax increases on their main home. It uses the same combined application, with the same November 2, 2026 deadline for the 2025 application.
- Local deductions, exemptions and abatements: the State lists these with its local property tax pages. Your municipal tax assessor can tell you which apply to your home.
These programs lower what you pay or what you get back. They do not change your assessed value, so an appeal and a relief application are separate steps.
How to appeal, step by step
- Wait for your notice of assessment. Gloucester County mails the Chapter 75 postcard on or before November 15. Check the date on yours, and call your municipal tax assessor if it has not arrived.
- Compare it with the market. Look at what similar homes near you sold for in the past year, and check the assessor's record for the wrong square footage, bedrooms, baths or condition.
- Call the assessor. Your municipal tax assessor can explain how your value was set and sometimes fixes a record error without an appeal.
- File Form A-1 with the county board. File online (credit card accepted, instant confirmation) or on paper with a check payable to the Gloucester County Board of Taxation. Online and in-person filings must be in by 4:00 p.m. on January 15. Use Form A-1 and the Comparable Sale form the State lists (Form A-1 Comp. Sale).
- Attach your evidence. Comparable sales, a recent appraisal, photos and repair estimates carry the most weight. Your evidence has to show the assessment is above market value under the standards above.
- Read the board's judgment. If you disagree, you can appeal to the Tax Court of New Jersey within 45 days of the date of the county board's judgment.
