ZIP Code 11947

With a per-capita income of $44,593, ZIP code 11947 sits in middle-income territory, anchored by the Stony Brook area. That earnings level pairs with an effective property tax rate of 1.73%, charged at the county level, which takes a meaningful bite out of ownership costs. Adding an 8.75% combined sales tax means everyday purchases carry a higher premium than in many parts of the country. Together, these figures describe a place where incomes are solid but not lavish, and where taxes on both property and spending shape the household arithmetic throughout the year.
