How Hunterdon County Assesses Property
Assessed by: Municipal Tax Assessor (supervised by Hunterdon County Tax Administrator)
Assessment cycle: annual
Notices typically mailed: January (by January 31st)
In Hunterdon County, New Jersey requires all properties to be assessed at 100% of true market value as of October 1st of the pre-tax year. This means your assessed value should equal your property's actual market value. For example: If your home's market value is $446,700 (the county median), at New Jersey's 100% assessment ratio your assessed value would be $446,700, resulting in approximately $8,523 in annual taxes at the county's effective rate of 1.91%. The county property tax portion alone at a rate of $0.306 per $100 would be approximately $1,367, with municipal and school taxes comprising the remainder.
The Appeal Process
Appeals are heard by the County Board of Taxation. Hearings before the Hunterdon County Board of Taxation are informal proceedings where you present evidence of your property's true market value. You do not need an attorney, though one may help for complex cases. The Board will review your evidence, hear from the municipal assessor, and issue a written decision.
Step 1: Review your assessment notice mailed by January 31st and compare your assessed value to recent comparable sales in your neighborhood. Gather evidence including 3-5 comparable sales from the past year, photos of property defects, repair estimates, and your property's tax assessment card.
Step 2: Consider an informal review with your municipal tax assessor before filing a formal appeal. Contact your local assessor to discuss your concerns and potentially resolve discrepancies without a formal hearing.
Step 3: Obtain and complete Form A-1 (Petition of Appeal) from the Hunterdon County Board of Taxation. Attach your comparable sales list (3-5 properties required) and include the filing fee. Ensure the form is signed and dated.
Step 4: File your appeal with the Hunterdon County Board of Taxation by the deadline (April 1 or 45 days from assessment notice mailing, whichever is later). The appeal must be received, not just postmarked. Mail copies of comparable sales to your municipal assessor at least 7 days before your hearing.
Step 5: Attend your hearing before the County Board of Taxation (typically scheduled May-July). Present your evidence including comparable sales, photos, and any expert appraisal reports. If using expert testimony, provide one copy of the appraisal report to the assessor and one for each Board member at least 7 days in advance.
Step 6: Receive the Board's decision, typically within a few weeks. If approved, your tax reduction applies to the current tax year. If dissatisfied with the result, you have 45 days from the decision date to file a further appeal with the New Jersey Tax Court.
Step 7: For properties assessed over $1,000,000, you may bypass the County Board and file directly with the Tax Court of New Jersey by April 1st, using the eCourts online filing system or paper complaint form.
