Where to find Will County property tax information
Will County maintains property tax records through the Will County Assessor's office, and you can search them online using the county's public database. The Assessor's office publishes property information including assessed values, tax amounts, and parcel details on their website at willcountyassessor.com. You can search by address, parcel number, or owner name to find the tax record for any property in the county.
The search tool is free and does not require registration. Results show the current assessed value, the tax year, and basic property details like square footage and lot size. If you need more detailed information — such as historical assessments, appeal records, or payment history — you may need to contact the Assessor's office directly or visit their office in Joliet.

How to search by address
Go to willcountyassessor.com and locate the property search tool on the homepage. Enter the street address exactly as it appears on the property deed or tax bill — include the street number, street name, and city. The search will return a list of parcels matching that address.
Click on the parcel that matches your property. The results page will display the assessed value for the current tax year, the property classification (residential, commercial, agricultural, etc.), and details like the number of bedrooms, bathrooms, and total square footage. You can print or save this page for your records.
How to search by parcel number
If you have the parcel number — also called the PIN or property identification number — you can search more quickly using that instead of the address. The parcel number appears on your property tax bill, the deed, or any recent assessment notice from the county.
Enter the parcel number in the search field on the Assessor's website. The system will pull up that specific property when ready. This method is useful if the address has changed, if the property is listed under a different name than you expect, or if you want to verify you are looking at the correct parcel before reviewing the tax information.
Understanding the assessed value shown in search results
The assessed value displayed in the online search is the value the Assessor has assigned to the property for tax purposes. This is typically lower than the market value or the price you paid for the property. The assessed value is multiplied by the local tax rate to calculate your property tax bill.
Assessed values are updated every three years in Will County as part of the reassessment cycle, though some properties may be reassessed more frequently if there have been major improvements or if you filed an appeal. If you believe the assessed value is incorrect, you can file a complaint with the Assessor's office or request a reassessment. The search results will show you the year of the current assessment.
What to do if you cannot find your property online
If your search returns no results or shows a property you do not recognize, verify that you have entered the address correctly — check for spelling, abbreviations, or directional prefixes (North, South, East, West). Some properties are listed under a different address than the one on the mailbox, particularly in rural areas or properties with multiple buildings.
If the address is correct and still no results appear, contact the Will County Assessor's office directly. You can call them at (815) 774-8500 or visit their office at 302 North Chicago Street in Joliet during business hours. They can confirm whether the property is in Will County and provide the correct parcel number and address as the county records them.
Difference between the Assessor and the Treasurer
The Will County Assessor determines the value of the property and sends that information to the Treasurer. The Will County Treasurer then calculates your tax bill based on that assessed value and the local tax rate, issues the bill, and processes payments. If you have questions about the amount you owe or need to make a payment, contact the Treasurer's office, not the Assessor.
The Treasurer's office is located at 302 North Chicago Street in Joliet as well. You can reach them at (815) 774-8500 to ask about payment plans, delinquent taxes, or to confirm whether your payment has been received. The Treasurer's office also maintains payment history and can tell you whether property taxes are current or overdue.
Frequently Asked Questions
Can I see how much property tax I owe using the Assessor's search tool?
The Assessor's search shows the assessed value, but not the actual tax bill amount. To find out what you owe, contact the Will County Treasurer's office or check your tax bill if you have one. The Treasurer calculates the final bill using the assessed value plus the local tax rate.
How often are Will County property values updated?
Will County reassesses properties every three years. Some properties may be reassessed sooner if major improvements have been made or if you filed an appeal. The search results will show the year of the current assessment so you know when the next reassessment is due.
What if I disagree with the assessed value shown online?
You can file a complaint with the Will County Assessor's office within 30 days of receiving your assessment notice. Contact the Assessor at (815) 774-8500 to request a reassessment or to learn about the appeal process. You may need to provide evidence such as recent appraisals or comparable sales in your area.
Is the information in the online search current?
The Assessor's online database is updated regularly, but there may be a delay between when changes are made and when they appear online. If you need the most current information or have questions about recent changes to your property record, call the Assessor's office directly.
