Property Tax Assessment Values Across Brentwood, Suffolk County, New York

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:

In Suffolk County, assessment notices are sent in the spring each year. They'll typically reach your mailbox by the middle of May.

For example, the median home price in Brentwood is $485,916, with a median property tax bill of $8,557.
