York Township Assessor

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

The 2020 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 2020 reassessment for real estate taxes payable 2021. As required by Illinois state statutes, it is the responsibility of my office to annually assess properties at one-third of the fair market value as of January 1st of each assessment year. As provided in the law, using sales that occurred in the prior three years, we will always lag behind the activity in the marketplace. When values/sales are decreasing, it will take multiple years for these changes to be reflected in local property assessments. When values/sales are increasing, this three year sales history ensures that assessments increase at a more even pace than may be seen in local markets.

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

It is expected that many property owners will want to discuss their assessments with office staff. I thank you in advance for your patience and understanding when contacting our office during this busy time. Wait times are expected to be long and response times may also be affected. We promise to work diligently to respond to all inquiries as promptly as possible so that you receive the best service possible.

Thank you,
