Assessor’s Office

The Assessor’s Office is responsible for determining the value of more than 184,000 parcels within the Town for the purpose of taxation. The office continually updates ownership records through deed transfers. Physical data is collected in order to maintain inventory records. This includes new construction, demolition, apportionment and consolidation of real property.

The Assessor’s Office is also responsible for the review and approval of all real property tax Exemptions. All applications and/or renewals for real property tax exemptions must, by law, be filed with the Assessor’s Office no later than March 1st of each year.


We recommend using our reservation portal to schedule an appointment with the Town of Brookhaven Assessor's Office, but walk-ins are welcome as well.
