Information on Appeals



The 2018 Assessments are estimated to be published early-mid August, 2018. The 2017 Appeal Information is below, but will be updated for the 2018 appeal period. 


Due to the volume of inquiries within the 30 day appeal period, we are asking our taxpayers to file a formal appeal with the McHenry County Board of Review and to file as early as possible once the appeal period has been opened.  As we review the appeals that are submitted to the Board of Review, our office may call you to sign a stipulation/agreement of assessment. 


1.  You are now able to file your assessment appeals online at McHenry County's website Please follow the instructions as indicated on the McHenry County Assessment Office E-Filing page.

2.  If you are filing your appeal by mail, or hand-delivering your appeal to McHenry County, please download the appropriate appeal packet for your property type: 2017 Residential Assessment Appeal Packet for McHenry County, 2017 Commercial Appeal Packet for McHenry County, or 2017 Industrial Assessment Appeal Packet for McHenry County from the McHenry County Assessment Office. Print out the appeal packet, fill out the information requested, and attach any evidence. 

3.  When completing your appeal form, you have the option for the Board of Review to make their decision based on the evidence provided (no oral hearing necessary).  At these hearings, neither township assessor nor property owner is present.  We recommend this option for most appeals. 

If the option is selected to have a scheduled, in-person hearing, you must be prepared to present your evidence.  The option for this type of hearing may be appropriate if you believe you have unusual circumstances that can best be stated personally.  The location, date and time of these hearings is determined by the Board of Review. 

4.  The completed appeal forms must either be filed online, officially postmarked (not metered mail date), or hand delivered to McHenry County on or before the deadline date. If mailing, or hand delivering, McHenry County requires two total copies of the appeal:  the original form and evidence plus one copy of the form and evidence.  You may also wish to make a copy for yourself. 

As our office receives the completed appeals from McHenry County, we will review each appeal and possibly call to stipulate on the assessment.


Comparable sales should be chosen as close to January 1, 2017 as possible.  Generally, the Board of Review advises sales be chosen from July 1, 2016 to June 30, 2017. 

In this current market, there are fewer comparable sales to choose from.  So it is our advice to do your best with what is available. The optimum sales would be good, "arms length" sales, occurring in your neighborhood or similar neighborhood.  The properties compared would be similar to yours in terms of size, age, style and condition.  Try to find sales that best represent your property.  If there are no sales in your immediate neighborhood, make a note of it.  

The idea is to paint an accurate picture to the Board of Review of what is going on market-wise in your particular area.  The optimum evidence would be three arms length sales of similar properties in your neighborhood. Bank REO and short sales may be accepted along with arms length sales, but keep in mind that many of the Bank REO properties were not in good condition at the time of sale, so may not be the best comparables to your property. 

Sales List

To better serve our township residents, we are providing a Sales List of sold properties in Dorr Township from July 1, 2016 - June 30, 2017.  This list must be used in conjunction with the Property Search feature on our website to help fill out the comparable grid on your appeal form.  Please note that some of the homes with low sale prices may have been in poor condition at the time of sale.

How to use the Sales List

1.  Use the list to help find your comparable sales. Find three comparable sales that are similar to your property.  For example, if you have a one-story, single family residence, try to find your comparable sales from this section of the list. 

2.  After choosing your comparable sales, go to our Property Search, and enter the Parcel Number or Property Address for each sale you chose.  Click on the property link to display the property record.  Fill out the comparable grid on your appeal form with the information on the property record. 

3.  Our office will also provide small photos of your property and your selected comparables when we submit our information to the Board of Review.  So, unless you wish to provide larger photos, your own photos are not a necessity. 

Please note there may be additional sales that you are aware of, that are not on the sales list.  These sales may have been recorded outside the timeframe of July 1, 2016 to June 30, 2017, or may not have been recorded as an arms-length sale.  These sales should still be able to be found under our website Property Search.
