The Assessor's Office is responsible for determining the assessed value of more than 99,000 parcels within the town for purposes 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 which include STAR (Basic & Enhanced), Veterans, Senior Citizen, Volunteer Firefighter & Ambulance Workers, Disability, Religious & Not-for Profit, Home Improvement, Business, First-Time Home Buyer and Agricultural. 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.


    STAR Exemptions: (two types)

Basic STAR - Available for owner- occupied, primary residences where the resident owners' and their spouses income is less than $500,000 exempts the first $30,000 of the full value of a home from school taxes.

Enhanced STAR - Provides an increased benefit for the primary residences of senior citizens (age 65 and older) with qualifying incomes exempts the first $65,300 of the full value of a home from school taxes as of 2016-17 school tax bills (unchanged from 2015-16) 

STAR exemptions apply only to school district taxes. They don't apply to property taxes for other purposes, such as county, town or city

  Please note the STAR Program changes *

As a result of recent law changes, some homeowners will receive a STAR check directly from New York State instead of receiving a school property tax exemption. The amount of your benefit will be the same regardless of how you receive it. 

Beginning with the 2016-2017 school year, new STAR applicants will need to register with the New York State Department of Taxation and Finance (NYSDTF) at www.tax.ny.gov/star   to receive a STAR check. Therefore, if you recently bought a new home in the Town of Islip or Suffolk County, you will need to register by September 1st to receive your check in December. If you register after September 1st, you will receive your check at a later date.

Current STAR exemption recipients

  • Current Basic and Enhanced STAR exemption recipients will keep their exemption, as long as they continue to own their current home.

  • NEW for 2019, New York State requires ALL Enhanced STAR exemption recipients to register with New York State’s MANDATORY Income Verification Program (IVP).

*Enhanced STAR exemption recipients, who are not already enrolled in the State’s IVP, must now file with the assessor:

Once enrolled in the State’s IVP, you will no longer annually renew your Enhanced STAR exemption with the assessor, but must comply with any requests from the New York State Tax Department of Taxation and Finance (NYSDTF). NYSDTF will notify you directly whether your income is below the Enhanced STAR limit.


*Current Low Income Senior Citizen exemption recipients who are Enhanced STAR exemption recipients, MUST now register with New York State’s MANDATORY Income Verification Program (IVP) in order to continue obtaining the Enhanced STAR exemption. File with the assessor your ANNUAL Low Income Senior renewal application – Form RP-467-Rnw, together with the following:

Once enrolled in the State’s IVP, you will no longer renew your Enhanced STAR exemption with the assessor annually, but must comply with any requests from the New York State Tax Department of Taxation and Finance (NYSDTF). NYSDTF will notify you directly whether your income is below the Enhanced STAR limit. YOU MUST, however, continue to renew your Low Income Senior exemption with the assessor annually by filing Form RP-467-Rnw, with proof of annual income.


* The New York State Department of Taxation and Finance has developed a web based registration application, and phone registration for the STAR Check program.  To register or to ask questions please contact the State at (518) 457-2036 or online at www.tax.ny.gov/star
