Notice of Revised Assessment:
This is notifying you of the new figures that will be used to calculate your tax bill in April 2019. Please note: Not every taxpayer will receive a notice each year. Properties that were changed at the local township level will be published and generate a notice to be sent to the taxpayer of record. Notices are not sent on properties that were changed by the multiplier alone.

Township multiplier: 1.0523
Every year the Department of Revenue conducts a sales ratio study comparing three years of sales to assessments. The Will County S/A uses this study to determine what factor is needed to bring a township’s assessment level to 33 1/3%. The 2017 multiplier of 1.0523 was calculated from 2015, 2016, and 2017 sales. That means an increase of 5.23% was applied by the county to residential assessments.

How do I know if I’m being fairly assessed?
Compare your assessment to similar properties in your neighborhood. Homes that are similar in style, size, age, location, and amenities, should have like assessments. Additionally, research recent sales in your neighborhood. Typically, comparable homes sell for similar amounts. Your assessment should reflect the market of your subdivision over the last three years. The “Property and Assessment Search” on this website can aid you with these tasks or we’d be happy to discuss the situation with you over the phone or in person.

How do I appeal my assessment?
If you feel that you are over-assessed, please call our office to discuss your concerns. Many issues can be resolved without filing a formal appeal. If we are unable to adjust your assessment, you may appeal to the Will County Board of Review. An attorney is NOT required for most residential homeowners (see Board of Review Rule #9). As a homeowner you have the right to represent yourself, free of charge. Appeal forms can be obtained either at our office or online at As always, we are happy to assist homeowners with the process.

Special Notice: If you have received a letter from a Real Estate Consultant or Tax Appeal Representative (in regards to appealing your assessment), please contact our office prior to spending money on those services. Many of those letters contain misleading or inaccurate information about your assessment and the appeal process. In most cases, a third party is not necessary to resolve an issue with your assessed value.
