New Trier Township 2026 Property Tax Assessment Notices: Key Dates & Appeal Guide

Property assessment notices for New Trier Township were mailed on May 7, 2026, by the Cook County Assessor’s Office. If you are a homeowner in this area, now is the time to review your assessed value and determine whether you should file an appeal.
Appeal deadline: June 22, 2026

What This Means for New Trier Township Homeowners

Even though New Trier Township was reassessed in 2025, homeowners are still eligible to appeal their property assessment again in 2026.

Many property owners assume they can only appeal during a reassessment year — this is not true.

You should consider appealing any year when:

• Your assessed value seems too high
• Comparable home values are lower
• Property details are inaccurate

💡 Why You Should Review Your Assessment Every Year

Property values across the Chicagoland area are constantly changing due to:

• Home sales and market trends
• Renovations and property improvements
• New construction in your neighborhood

Because of these shifts, your assessment may no longer reflect the current market value of your home.

Important:
A successful property tax appeal in 2026 could potentially reduce your tax burden for up to two years, until the next reassessment cycle in 2028.

Don’t Wait for a Reassessment Year

One of the most common mistakes homeowners make is only appealing during the triennial reassessment year.

The reality:
You can appeal every year — and doing so ensures you:

• Avoid paying more than your fair share in property taxes
• Keep your assessed value aligned with the market
• Maximize long-term savings
