Assessment Review

Tax Appeals are filed with the County Tax Board or NJ Tax Court between January 10th and April 1st each year.  If at a point AFTER the appeal deadline has passed, a property owner feels aggrieved because their assessment is "out of line" with other similar properties in Town, they can persue an Assessment Review.  Reasons for this type of review generally deal with a recent sale or listing of your property, or based on comparable sales activity similar to your property.  On occasion a Review might also be relevant to correct factual data about your land or building. 
The review process involves filling out a questionnaire dealing with the specific facts about your property and any issues that are of relevance. Feel free to provide any attachments that your feel contribute to your position.  The Assessment Reviews occur between October 15th and December 15th, in order to implement any necessary changes to the Tax Book effective January 1st of the following year. If a review results in no change to the assessment, the property owner will be notified of this decision by mail, and informed about the Appeal Process available to them.

Property Assessment/Ratio/Equalized Valuation:

Property is assessed by a certified tax assessor according to a standard measure of property, namely the true or market value. The market value is what a knowledgeable buyer would be willing to pay on the open market. Once a home is assessed, it is only reassessed if a change occurs that warrants reassessment or if a town reassesses. Periodically, town-wide assessments occur to re-value all the property in a town. The town reassessed its property in 1990. New construction and changed assessments occur as of October 1 of the pre-tax year. In 1998, the total assessed valuation of all property within the Township was $850,110,972.

Since homes are not assessed annually, the assessment does not keep up with market value. To account for this variance, assessments are expressed in terms of a ratio to true value. In 1999, the Township is assessing at an average of 87.97% of market value. The ratio, or equalized valuation, is then used to apportion the costs of county government or district schools equitably among taxing districts.

  •  Tax Appeals/Special Assessments:
  • Components of Tax Rate/History:
  • Tax Bill Calculation/Tax Billing:
  • Tax billing:

Property taxes are levied as of January 1 on property assessed as of the previous calendar year. Tax bills are issued annually at the end of June. The bill is due in four installments namely February 1, May 1, August 1, and November 1. Since the new tax rate is not determined until June of the current year, the February and May installments are estimated. In turn, the August and November installments are based on the newly certified tax rate for the current year less the estimated tax paid in the first installments. See the example below:

In the previous example, the average tax payer owed $8,005.71 in 1998. However, this was not paid in four equal installments. The first two installments (Feb, May) were estimates billed in the June 1997 tax bill. The last two installments (Aug, Nov) were billed in June 1998. These figures were determined by calculating the taxes due with a tax rate of $1.99 ($78,005.71) less the taxes that were billed for February and May.

  • Tax Collection:
  • Tax Deductions:

Deductions for Veterans, and Senior Citizens or Disabled Persons, and their surviving spouses are available. Veterans are eligible for a $250 annual deduction. Seniors and Disabled Persons qualify for a $250 annual deduction if their income is $10,000 or less in the pre-tax year, excluding Social Security. Forms may be obtained from the Finance Office.

While taxes are due on February 1, May 1, August 1, and November 1, a ten day grace period is in effect. After ten days, interest will be accrued back to the first day of the month. Interest is calculated at 8% for the first $1,500 and 18% thereafter. A 6% year end penalty will also be assigned for unpaid taxes in excess of $10,000 on December 31 of the current year. Liens will be sold on properties that have unpaid prior year taxes as of the date of a tax sale set by the Tax Collector. In order to permit time for payment of prior taxes plus interest and be removed from the tax sale list, homeowners will be duly notified if a lien is scheduled to be sold at tax sale. Furthermore, a tax sale list will be advertised in the newspaper in advance of the tax sale.

The average assessment in the Township is $402,297. In order to determine how much the average homeowner pays in taxes, the following calculation is used. The assessment is divided by $100 and multiplied by the tax rate (expressed per $100 of assessed valuation) to determine annual taxes. For example:

($402,297/$100)* $1.99= $8,005.71

   The Township collects taxes to support the budgets of the county, the schools, and the municipality. As a result, the total tax rate is the sum of several tax rates. The municipal portion (including the municipal open space tax) represented $0.44 or 22% of the 1998 tax rate of $1.99 per $100 of assessed valuation. Tax rates are determined by taking the budget less outside revenues to isolate the amount to be raised by taxation. This amount is then divided by the total assessed valuation and multiplied by $100 to express the tax rate in terms of $100 of assessed valuation. See the following graphs and chart for a history of the tax rate.

Appeals of assessments are heard by the County Board of Taxation and the Tax Court of New Jersey. Appeals must be submitted on or before April 1.

Farmland property receives a preferential assessment based on productivity and agricultural or horticultural use of the land. Application for farmland assessment must be filed annually on or before August 1.
