ZIP Code 12831

Households in ZIP code 12831, near Ballston Lake, earn a median of $100,024, with per-capita income at $51,812 — placing the area solidly in middle-to-upper-income territory rather than working-class. Homes carry a median value of $343,100, and the county-level property tax rate of 1.40% translates into a meaningful annual bill on that assessment. Add the 7.00% combined sales tax on purchases, and the overall tax picture reflects a comfortable but not wealthy community, where earnings support homeownership while state and local levies take a steady share.
