Property Taxes

Newark residents pay real estate taxes based on the assessed value of their homes, as determined by New Castle County’s Assessment Office. When a certificate of occupancy is issued after a building is constructed or improved, an assessor visits the property to determine the new assessment rate. The property assessment determines the amount of your property tax bill, as well as your school district’s tax bill.
