Property Tax Assessment Values Across Newark, New Castle County, Delaware
When examining property taxes in Newark, Delaware, understanding the distinction between "market value" and "assessed value" is crucial.

The assessed value is the market value minus any applicable exemptions or limits determined by local laws and offerings. The tax assessed value is the figure used to calculate your property taxes or the amount multiplied by your tax rate to get your tax bill.
Assessment notices are sent in the spring each year and typically reach your mailbox by the middle of May. Each property owner receives an assessment notice that contains both the market value and assessed value, along with an estimate of your property tax bill.
