Tax Assessor Information

The Tax Assessor is responsible for assigning the value of real property within Raritan Township. This value is an assessment, which is used as a basis for taxation. The Tax Assessor is responsible for the maintenance of ownership lists and property transfers. The Tax Assessor also represents the township in all tax appeals.

Each year by January 31st, the Hunterdon County Board of Taxation mails a postcard to every property owner with the current year tax assessment and the net property taxes billed for the prior year. Each homeowner should review the assessment for correctness and contact the assessor with any questions. This postcard also contains appeal instructions if a homeowner disagrees with the assessed value shown. Assessment appeals must be filed on or before April 1st of the current tax year. State law requires the Tax Assessor to assess all real property on a yearly basis by October 1st.

TAX APPEALS - Please note that you cannot appeal your taxes, only your assessment. If you are dissatisfied with your tax assessment, you may speak with the tax assessor. If after speaking with the tax assessor, you wish to contest your assessment, you may file an appeal to the Hunterdon County Board of Taxation. This may be done between February 1st and April 1st of each year.

TAX DEDUCTION INFORMATION – Senior Citizen, Veterans and Permanently or Totally Disabled Person deductions and/or exemptions are available for NJ Property Owners.  Please contact the Assessor’s office for eligibility requirements and applications.

FARMLAND ASSESSMENT:  Land devoted to agricultural or horticultural use may be assessed for property tax purposes on its value for those uses as well as its productivity rather than on the market value of the land for any other use. To qualify, the land must be a minimum of five acres which is devoted to agriculture or horticulture for at least two consecutive years prior to the tax year and must continue in that use until the end of the tax year for which the claim is made.  Please contact the Assessor’s office for additional information.
