Where to look for Will County property tax records
Will County Assessor's office maintains the public records you need to find real estate tax information for any property in the county. You can search their database online without visiting an office or paying a fee. The Assessor's website lets you look up a property by address, parcel number, or owner name.
The Will County Assessor is located in Joliet and serves all unincorporated areas of the county plus some municipalities that contract with the office. If your property is in a city like Naperville, Bolingbrook, or Downers Grove, that city may maintain its own assessment records, though Will County Assessor records are still public and searchable.
Start at the Will County Assessor's property search portal. You will need either the street address or the parcel identification number (PIN). The PIN is a unique number assigned to every property and appears on your tax bill and deed.

What information appears in the Assessor's database
The Will County Assessor's records show the assessed value of the property, which is the value used to calculate your tax bill. This is different from market value or sale price. The assessed value is typically a percentage of market value and is set by the Assessor's office based on recent sales of comparable properties.
The database also displays the property characteristics: lot size, building square footage, number of bedrooms and bathrooms, year built, and type of construction. You will see the owner's name as it appears on the deed and the mailing address on file. Some records include a property sketch or map showing the lot boundaries.
The Assessor's records do not show the actual tax bill amount you owe. To find that, you need to contact the Will County Treasurer's office or check your tax bill directly. The Assessor sets the value; the Treasurer collects the tax based on that value and the tax rates set by your school district, municipality, and other taxing bodies.
How to read your Will County property tax bill
Your tax bill arrives by mail from the Will County Treasurer, usually in late spring for the taxes due that year. The bill shows the parcel number, property address, assessed value, and the total tax amount broken down by taxing district. Each line item represents tax owed to a different entity: your school district, municipality, library, park district, and county.
The bill also lists any exemptions you hold, such as homeowner's exemption, senior exemption, or disability exemption. These reduce the assessed value before the tax rate is applied, which lowers your bill. If you believe you are may have access to to an exemption you do not see listed, you file a claim with the Assessor's office by a set important date, usually in late spring.
Payment instructions appear on the bill. You can pay online, by mail, or in person at the Treasurer's office. If you pay late, a penalty is added. The Treasurer's website shows payment important date and current payment status for your property.
Understanding assessed value versus market value
The assessed value in the Assessor's database is not the same as what your home is worth on the open market. Illinois law requires the Assessor to assess property at a percentage of fair market value. In most of Will County, this percentage is 33.3 percent, meaning a home worth $300,000 would be assessed at $100,000.
The Assessor determines assessed value by studying recent sales of similar properties in your area. If you sell your home, the sale price does not automatically change your assessed value. The Assessor may adjust it in the year following the sale if the price suggests the previous assessment was inaccurate, but this is not automatic.
If you believe your assessed value is too high compared to recent sales of similar homes, you can file a formal objection called an appeal. The important date to file is usually in late spring, and you must do so with the Will County Board of Review, not the Assessor's office. The Board of Review hears appeals and can lower, raise, or uphold the assessment.
How exemptions affect your tax bill
Will County offers several exemptions that reduce your assessed value and therefore lower your tax bill. The homeowner's exemption is available to owner-occupants and reduces the assessed value by a set amount that varies by year. Senior citizens, disabled persons, and veterans may be may have access to to additional exemptions with higher reductions.
To claim an exemption, you file an process with the Will County Assessor by the important date, usually in late spring. You must provide proof of your status: a birth certificate or ID for age, a disability information letter from Social Security or the VA for disability, or a discharge certificate for veteran status. The Assessor's office has process forms and instructions on their website.
Once approved, the exemption appears on your tax bill and reduces your assessed value each year. You do not have to reapply annually unless you move or your status changes. If you sell the property, the new owner must explore for exemptions separately.

Frequently Asked Questions
How do I find my parcel number if I do not have my tax bill?
Your parcel number appears on your property deed, mortgage statement, and homeowner's insurance policy. You can also call the Will County Assessor's office with your street address and they will provide the parcel number. Once you have it, searching the Assessor's database is faster and more accurate than searching by address alone.
Why is my assessed value different from what I paid for my house?
Assessed value is set by the Assessor based on a percentage of fair market value, not on what you paid. If you bought your home years ago, the assessed value may be lower than your purchase price. If you bought recently, the assessed value may be lower than the sale price because the Assessor uses a percentage, typically 33.3 percent in Will County.
Can I look up someone else's property tax information?
Yes, Will County Assessor records are public. You can search any property by address or parcel number and see the assessed value, property characteristics, and owner name. Tax bill amounts are not public, but the Assessor's assessment information is available to anyone.
What happens if I do not pay my property tax bill on time?
A penalty is added to your bill if you pay after the important date. The Will County Treasurer's office can tell you the current penalty rate and your payment status. If taxes remain unpaid for a long time, the county may place a lien on the property or begin foreclosure proceedings, though this process takes years.
How often does the Assessor update property information?
The Assessor reviews all properties in Will County on a regular cycle, typically every three to four years. If you make major improvements to your home, the Assessor may update the record sooner. You can request a reassessment if you believe the information in the database is incorrect or outdated.
