You & Your Assessment

As with almost everything, inflation also causes local government, county government, and school costs to rise.

The tax rate on your bill is determined by the County Board of Taxation based on budgets submitted by the municipality, county and schools, and the total assessed value of the municipality.

Tax Information

With changes in budgets, tax rates, and assessments all affecting the tax you pay, the key to your Real Estate Tax is the bottom line of any budget: "Amount to be raised by Taxation."

Presently, state school aid, part of which comes from the State Income Tax, is based on equalized valuation of assessments. The State Constitution requires all properties be assessed at "fair market value." Therefore, it is essential to maintain assessments, keep up with market prices and cope with inflation. At times, market conditions warrant Revaluation or Reassessment programs to maintain "fair market value."

Enjoy Your Property - Maintain It

On a normally maintained property, the following improvements may not bring an increase in the individual assessment: Painting, Landscaping, Minor Repairs, Decoration.

The following items may affect the assessed value: 

  • Conversion of attic, basement, garage, or porch into living area
  • Installation of bath or powder room, Central Heating / AC, Fireplace, Porch or Patio, Additions, Garages and other structures, In Ground Swimming Pools, Siding

Added Assessment

The added Assessment will be effective the 1st of the month following substantial completion, occupancy, or use. The Added Assessment list is submitted to the County Board on October 1st and the tax thereon is due in full November 1st of the same year. If you wish to demolish an old building, consider its tax cost and usefulness before you tear it down. 

Remember that any building standing as of October 1st of the pre-tax year may be taxable for the entire following year. Also, a demolition permit is required from the Construction Code Official. This also applies to swimming pools.
