Mchenry township Assessor's office updates

Hello McHenry Township Residents,

Here we are, almost spring!

The McHenry County Assessments Office will be mailing out the Low-Income Senior Assessment Freeze Homestead Exemption forms to those who have had the exemption inn the past on March 6, 2026. 

My office will be receiving the forms after they are mailed by the County. I strongly recommend that you call my office and make an appointment should you need assistance completing your freeze form. 

Please check out our McHenry Township Property Search. You may now see a photo and drawing of your property and the property characteristics have been simplified. You can look at comparable sales, comparable assessments, as well as links to the McHenry County GIS and McHenry County Tax Bills. . Here is the link: https://search.mchenrytownship.com/search

As a reminder, you may see our Township vehicles in your area, and this is an indication that we are updating our property records to make sure we have everything correct. My field staff is there only to collect information, including current photos and any updated information needed. If you have additional questions, please contact my office. 

Sincerely, 

Mary Mahady, C.I.A.O.  – McHenry Township Assessor
