Did your New Trier Township property tax bill jump?

On the North Shore the assessed value, not the rate, is where the money lives — a small error on a Wilmette or Winnetka home is real dollars.

About New Trier Township & its taxes

New Trier Township is the North Shore: Wilmette, Kenilworth, Winnetka, and Glencoe in their entirety, plus the eastern third of Northfield and slices of Glenview — some of the highest-value residential real estate in Illinois.

It carries the lowest typical composite rate in our pilot — about 7.8% across a 22-tax-code sample — but a low rate on a seven-figure assessment is still a five-figure bill. Here the assessed value, not the rate, is where the money lives.

On a New Trier home, a one-percent assessment error is worth more dollars than a five-percent error on most Cook County properties — which is why the North Shore has long had the county’s most active appeal culture. Fresh 2025-cycle values that outran the local median are worth checking now rather than waiting for 2028.

New Trier Township tax rates, at a glance

Across a sample of 2,000 residential (Class 2) parcels in New Trier Township, spanning 22 distinct tax codes, the typical (median) composite tax rate is about 7.8% — ranging roughly 7.7%–8.4% depending on the exact overlapping school, municipal, and park districts for your parcel.

How property tax appeals work in New Trier Township

The North suburbs' most recent reassessment was 2025, so New Trier Township's current values are already on the books — the Assessor's own 30-day appeal windows for that cycle have largely passed. What remains open is the Cook County Board of Review, which takes appeals in an annual window every year, reassessment year or not, until the next reassessment in 2028.
