From McHenry County:
Assessment Notices Posted for Seneca and Burton Townships
WOODSTOCK, Ill. – Assessment notices have been posted online for property owners in Seneca and Burton Townships.
Property owners may access their assessment by visiting the McHenry County Property Tax Inquiry Portal here..
Assessment notices on computers and tablets can be accessed by clicking the “Property Assessments Notice” link on the right-hand side of your property tax information.
On smart phones, the Assessments tab can be found by clicking the three-line “hamburger” icon in the upper right-hand corner.
Please note that your assessment notice is not a property tax bill – your 2026 assessment is used to determine the taxable value of your home for property taxes due next year.
The notice also includes information on your existing exemptions, and it lists other available exemptions.
Property owners in Seneca and Burton townships will have a 30-day period from the Oct. 7 date of publication to file an appeal with the McHenry County Board of Review, ending at midnight on Friday, Nov. 6.
You can file an appeal request by visiting the McHenry County Assessments webpage.
This year and going forward, McHenry County properties that are only adjusted by their equalization factor [township multipliers] will no longer receive a mailed copy of their assessment.
The Assessments Office will still mail physical notices for re-evaluations, farmland, and new properties.
The County Board made the switch to online assessment notices to save taxpayers more than $65,000 a year in postage costs.
