ZIP Code 11703

Households in ZIP code 11703, centered on Stony Brook, earn a median of $137,158, placing the area well into affluent territory. Per-capita income of $50,060 and a median home value of $521,700 reinforce that standing. The county-level property tax rate of 1.73% means owners of a home at that median value owe roughly $9,000 annually, a substantial carrying cost even at this income level. Add an 8.75% combined sales tax on purchases, and the overall tax load is heavy, though the local earnings base is strong enough to absorb it.
