                   Assessor Issues Decisions on 2019 Assessment Appeals

Cook County Assessor Fritz Kaegi has issued his decisions on the 2019 New Trier Township re-assessment appeals. The Assessor’s decisions are sent by U.S. Mail to all taxpayers who filed timely appeals. The Assessor also announced that any request for re-review of his decision must be filed by Tuesday, July 2, 2019 at 5:00 p.m. If you choose to file a request for re-review, go to the Assessor’s website:; click on “Forms,” then click on “Appeals”; then click on “Residential.” About two-thirds of the way down the list, you will find the “Re-Review Form.” Complete it and send it to the Assessor’s office according to the instructions at the bottom of the form. You must print the form. You cannot send it online.

If you wish to fax your Re-Review request and don’t have access to a fax machine, you may bring your completed form to us at the Township Offices by 5:00 p.m. on Monday, July 1. If you wait until Tuesday, we cannot guarantee timely receipt by the County Assessor because we have no way of knowing how busy the dedicated fax line will be – and it is a holiday week.

Re-Review does not affect your ability to file a complaint with the Board of Review. The Board of Review is a separate board, and all property owners in Cook County have the right to appeal to it annually.
