Understanding Property Taxes in Mchenry County

Property taxes are a crucial revenue source for local governments, funding essential services like schools, fire protection, and infrastructure development. In Mchenry County, the property tax system is governed by the Illinois Property Tax Code, which outlines the assessment and collection processes.
Assessment Process
The assessment of properties in Mchenry County is carried out by the Mchenry County Assessor’s Office. The office is responsible for determining the fair market value of each property, which serves as the basis for calculating property taxes. Assessments are conducted regularly, with the aim of ensuring that property values are up-to-date and accurately reflected in the tax system.
The assessment process involves several steps. Firstly, the assessor’s office gathers data on recent sales of similar properties in the area. This data is used to establish a baseline for property values. Subsequently, the office conducts physical inspections of properties, evaluating factors such as size, condition, and any recent improvements or additions.
Once the assessments are completed, property owners receive a notice of the assessed value. If a property owner disagrees with the assessment, they have the right to appeal, and the assessor’s office provides a detailed process for resolving such disputes.
Tax Rates and Calculations
Property taxes in Mchenry County are calculated by applying a tax rate to the assessed value of a property. The tax rate is determined by the various taxing bodies within the county, including the county government, municipalities, school districts, and special taxing districts.
Each taxing body sets its own tax rate, which is expressed as a percentage. These rates are then combined to form the aggregate tax rate for a particular property. The aggregate tax rate is then multiplied by the assessed value of the property to determine the annual property tax obligation.
| Taxing Body | Tax Rate (%) |
|---|---|
| Mchenry County | 2.10 |
| City of McHenry | 1.75 |
| Community Unit School District 15 | 1.50 |
| Mchenry Park District | 0.50 |
| Aggregate Tax Rate | 5.85 |

In the above example, a property with an assessed value of $200,000 would have an annual property tax bill of $11,700, calculated as follows: $200,000 x 0.0585 = $11,700.
