Stony Brook, NY — income, home value, property tax, and sales tax.
In ZIP code 11794, which covers part of Stony Brook, per-capita income sits at just $4,800 — a figure shaped largely by the student population attending the local university rather than by typical household earnings. That low income level makes the 8.75% combined sales tax a real consideration on everyday purchases, since it adds noticeably to the cost of goods. Property taxes in the surrounding county run at an effective rate of 1.73%, a charge that would weigh heavily against such limited earnings for anyone owning property here. Budgeting in this ZIP means stretching every dollar, with housing and sales taxes consuming a substantial share of what comes in.
