The tax laws in Suffolk County state that payment of taxes on a timely basis is the responsibility of the property owner even if a tax bill has not been received. The property owner will be liable for all penalties and interest on late payments.
As tax bills are sent out in December for the tax year commencing on December 1 any person who purchases property in Suffolk County during the year should determine if any taxes remain unpaid on the property and, if the taxes remain unpaid, please contact the Receiver’s Office to determine the amount due.
Town, school, and county taxes in Suffolk County cover the period from December 1 to November 30 of the following year.
Please include the payment stub(s) with your remittance. Make checks payable to and mail payments to:
Annmarie Seddio, Receiver of Taxes
P.O. Box 1854, 38 N Ferry Rd, Shelter Island, NY 11964-1854
Method of Payment
Taxes are payable by check, cash, money order in the exact amount. Checks will be accepted subject to collection for which this office assumes no responsibility.
Payments by Mail
If taxes are paid by mail, pursuant to Real Property Tax Law 925, you will avoid penalty and interest charges if the payment envelope bears proper postage and an official post office date stamp (a private meter stamp is not acceptable) dated no later than the last due date. If no date stamp is indicated on the envelope, by statute, the date received is the date paid. No cash by mail.

Returned checks or orders will automatically cancel your tax payment and will not necessarily be redeposited.
