Tax Year - Town, School and County Taxes in Suffolk County cover the period from December 1st to November 30th of the following year. Taxes Payable to Town Receiver - Town, School and County taxes are payable to the local Tax Receiver in each Town from December 1st to and including May 31st. Taxes may be paid to and including January 10th without penalty. The second half tax is due and payable on May 10th, but may be paid before this date if the taxpayer wishes. After May 31st of each year all taxes are due and payable to the County Treasurer.
Interest is calculated on the total of flat tax and penalty.
Any taxes remaining unpaid after August 31st will also be charged a tax sale advertising fee. If taxes have not been paid prior to the date of tax sale, a tax lien will be sold for such unpaid taxes and accrued charges. Change of Address - The Assessor or Board of Assessors in each Town is charged with the responsibility of placing an assessment valuation upon real estate and indicating the assessed owner thereof. It is therefore, necessary for the owner of property to notify the Assessor or Board of Assessors in the Town in which his property is located if there is any change of his mailing address. The Assessor should be notified of such change immediately so that correction of the assessment roll can be made and tax bills mailed to the proper address in December.
