McHenry County Property Tax Law
Property records in McHenry County are governed by the Illinois Property Tax Code (35 ILCS 200/). This law sets the rules for how property gets assessed and taxed across all 102 Illinois counties. Under 35 ILCS 200/, all real property must be assessed at 33 1/3 percent of its fair market value. McHenry County follows this standard. Township assessors set the initial values, and the county office checks that those values are uniform and fair.
The lien date is January 1 each year. That is the date when the county locks in who owns the property and what its assessed value is for that tax year. Tax bills in McHenry County go out the following year because Illinois property taxes are paid in arrears. The assessment cycle for McHenry County is quadrennial, meaning a full reassessment happens every four years. Annual adjustments keep values current in between those full reviews. If you disagree with your assessed value, you have about 30 days from the date of the assessment notice to file an appeal.
McHenry County Property Assessors by Township
McHenry County uses the township assessor system that covers most of Illinois. Each township has a local assessor who visits properties, reviews conditions, and sets assessed values based on fair market value. These assessors are the first point of contact if you have a question about your property record. They can explain how they arrived at your value and fix errors if they find one.
Common townships in McHenry County include Algonquin, Crystal Lake, McHenry, Woodstock, Marengo, and Nunda. Each township assessor reports values to the McHenry County Office of Assessments for review. If the county finds that values across a township look uneven, it can apply equalization factors to bring them in line with state standards under 35 ILCS 200/. The township assessor is also the person who can help you file for exemptions on your McHenry County property records.
You can find a list of township assessors and their contact details on the McHenry County assessments page. Call the assessor for your township first if you have questions about a specific parcel.
McHenry County Property Tax Exemptions
Several property tax exemptions are available to McHenry County homeowners. These exemptions reduce your assessed value and lower your tax bill. They show up in your property records once approved. The McHenry County Office of Assessments processes all exemption applications along with the township assessors.
The General Homestead Exemption is the most common one. It cuts $6,000 from your assessed value if you own and live in the home. No age limit applies. The Senior Citizens Homestead Exemption takes off an extra $5,000 for homeowners who are 65 or older. If you meet income limits, the Senior Citizens Assessment Freeze locks your assessed value so it does not go up each year. A Disabled Persons Homestead Exemption gives a $2,000 reduction. Veterans with service-connected disabilities can get larger reductions through the Disabled Veterans Homestead Exemption based on their rating. The Returning Veterans Homestead Exemption provides a one-time $5,000 cut for qualifying veterans in McHenry County. Under 35 ILCS 200/, these exemptions are defined by state law but applied at the county level.
To apply, contact the McHenry County Office of Assessments or your township assessor. Most exemptions need a short form and proof of eligibility. Once approved, many renew each year on their own.
Note: Some McHenry County exemptions require annual renewal, so check with the office to make sure yours stays active.
McHenry County Property Assessment Appeals
If you believe your assessed value is wrong, you can appeal it. Start with an informal talk with your township assessor. Bring evidence like recent sales of similar homes or an independent appraisal. Many issues in McHenry County get fixed at this step without filing anything formal. The assessor can make corrections right then if they find an error in the property record.
When the informal review does not resolve the matter, you can file a formal complaint with the McHenry County Board of Review. The board will look at your evidence, compare your parcel to similar ones, and decide if a change is needed. Under 35 ILCS 200/, the Board of Review has the power to adjust assessed values in McHenry County. You usually get about 30 days from the date of your assessment notice to file. The notice will state the exact deadline. If you miss the local window, you can still appeal to the Illinois Property Tax Appeal Board at the state level, though that process takes more time.
Changes from an appeal will show up in your McHenry County property records once the board or state board makes its decision.
