A few clicks from the comfort of your home.

You have 2 opportunities to appeal your Cook County property taxes every year, our service includes both appeals for a calendar year, if you miss the first appeal at the Assessor’s office we will go directly to the Board of Review.

The evidence:

If you choose to use our service we will analyze all of the data from the properties in your neighborhood and land-use code. We will look at several factors including square footage, construction type, age, building assessed value, and overall assessed value. Our analysis will provide the necessary evidence that will prove that you are over assessed, and paying too much in property taxes. This evidence will be used to present a lack of uniformity appeal.

The Assessor

The first opportunity to appeal is at the Cook County Assessor, which generally opens for appeals between from January through October. Each Township receives a 30 day time period in which to appeal, and exact dates are not released in advance, but the Assessor posts a general timeline in January. Our service keeps track of all dates and deadlines very closely, and can provide you an idea of when you can expect your township to open for appeal. The Assessor’s appeal is a basic appeal, we will submit 6 comparable properties on your behalf, and file based on a lack of uniformity. The Assessor usually reviews the case and posts results within 60-90 days from the appeal deadline. They will send a letter with results as well via US Mail.

Board of Review

The second appeal is at the Cook County Board of Review, which generally opens for appeals from August through February. Each township receives a 30 day time period at the Board of Appeal. Exact dates are not released in advance. It is imperative that if you plan on appealing that you get signed up as soon as possible, this will insure you do not miss any deadlines. The Board of Review is a more extensive appeal. All required documentation, and processes will be completed and submitted on your behalf by our in-house attorney, this will include your settlement statement of a recent purchase, attorney authorization, nine comps, pictures of the comps, a complete square footage breakdown of the comps, and an attorney brief requesting the lowest possible evaluation. Results are posted online at the Board of Review website about 90 days after the appeal closes. They will not mail results, but you can easily access online with your PIN number.
