Property Tax Assessment Values Across Block Island, Washington County, Rhode Island

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 the month. Each property owner receives a notice that contains both the market value and assessed value, along with an estimate of your property tax bill.

For example, the median home price in Block Island is $1,183,600, with a median tax bill of $6,534. The highest median home price is in 02807 at $1,183,600, and the median tax bill is well above the national median property tax bill of $2,400.
