Any questions regarding assessments may be addressed to the York Township Assessor's Office, 630-627-3354.

The 2019 assessments are now available in the Property Record Search.  Please check our Dates to Remember page for more information on publication and filing dates.

The Assessor's Office is charged by the state to estimate the market value of the more than 46,000 parcels of property within York Township--then assess each property at one-third of market value. Real estate taxes to support the various taxing bodies are based on these assessments and result from those taxing districts applying their tax rates to assessments. Governing boards elected in each district set the budgets for that taxing district.

The Assessor's Office can also provide additional information on the many facets of the assessment cycle, appeal process, and senior exemptions. Residents are welcome to call or stop by to discuss their assessment concerns.

From the Assessor...

My staff and I have recently completed the 2019 General Reassessment.

As required by state statutes, we have reassessed ALL real property located in York Township. This reassessment involved an examination of sales activity that occurred during the preceding 3 years (2016, 2017, & 2018). Using these sales, we determine the fair market value of real estate and assess at 1/3 of indicated market value. It should be noted, the three-year sale activity requirement means our assessments will historically lag behind market activity.

Property valuations are made by certified personnel who live in our communities and who have a vested interest in providing fair, accurate, and equitable assessments. As homeowners and property tax-payers ourselves, we know the assessment process can be confusing. We work every day to ensure we have accurate information on the more than 46,000 parcels in York Township, and our goal is to provide personal and responsive service to all our constituents.

As a result of the 2019 General Reassessment, it is anticipated that many property owners will want to discuss their assessment with office staff. We have added additional functionality to our website that will allow you to contact office personnel directly related to your inquiry. However, your understanding of increased wait times when contacting our office during this busy time is greatly appreciated. We thank you in advance for your patience and will work diligently to respond to all inquiries in the order they are received and as promptly as possible.

Thank you.
