Sign up for Email Alerts for Your Property’s Assessment
WOODSTOCK, Ill. – Assessment notices will be posted online tomorrow (Saturday, Oct. 17) for property owners in Algonquin Township.
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 Algonquin Township will have a 30-day period from the Oct. 17 date of publication to file an appeal with the McHenry County Board of Review, ending at midnight on Monday, Nov. 16.
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 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.
Property owners are encouraged to visit the Assessments Office website to sign up for email alerts and text messages when assessment notices for your township are published.
Assessment notices have already been posted for property owners in Richmond, Chemung, Dorr, Grafton, Greenwood, Coral, Hartland, McHenry, Alden, Nunda, Seneca, Burton and Hebron townships.
The appeal deadline for Alden Township is Thursday, Oct. 22, the deadline for Nunda Township is Monday Oct. 26, the deadline for both Seneca and Burton townships is Friday, Nov. 6, and the deadline for Hebron Township is Thursday, Nov. 12.
