Westchester property taxes — the short version
Two almost-identical houses on opposite sides of a town line can have tax bills that differ by $8,000/year. Here's why, and how to spot it before you write an offer.
The three bills you're actually paying
A Westchester tax bill isn't one number — it's three stacked together:
- County tax — Westchester County, relatively stable across towns
- Town/village tax — varies, usually the smallest slice
- School tax — the biggest single item, often more than half the bill
School tax is where adjacent towns diverge dramatically. A home in one district vs a neighbor across the line can differ by thousands annually simply because the districts levy differently.
Assessment vs market value
New York towns can assess at anywhere from 1% to 100% of market value. Comparing the raw tax number is misleading — you need the effective rate: annual tax divided by actual market value. Most buyers skip this and end up surprised.
Star exemption and grievance
Basic STAR (New York state) knocks several hundred to a couple thousand off for most owners. Enhanced STAR is for 65+ with income limits. And the annual grievance window(typically May/June) is where overvalued assessments get corrected — most owners never file.
What this means for your search
Two questions I run for every client when we look at a home:
- What's the effective tax rate of this specific house at today's market value?
- How does that compare to the 3-5 closest comps in adjacent districts?
That math usually shifts which town ranks first. It's the single biggest "surprise" in Westchester buying, and the main reason I lead tax conversations early, not late.
