Where to find your property tax statement online
Illinois does not have a single statewide system for property tax statements. Instead, each county assessor's office maintains its own records and online portal. To find your statement, you need to go to your specific county's assessor website, not a state-level database.
Start by identifying which county your property is in. Then search "[Your County Name] Assessor" plus "property tax statement" or "online records." Most county assessor offices in Illinois now offer free online access to property information, though the exact name and format of what you can view varies by county.
Some counties call it a "property tax statement," others call it a "tax bill," and still others label it "assessment information" or "parcel information." All of these refer to roughly the same document showing your property's assessed value and the taxes owed.
Key Takeaways
- Illinois property tax statements are kept by county assessor offices, not by the state, so you must visit your county's website to find yours.
- You will need your property address or parcel number to search for your statement online; most county systems accept either one.
- Some counties require you to create a free account to view full details, while others display basic information without logging in.
- If your county's website does not offer online access, you can request a paper statement by phone or email to the assessor's office.
- Property tax statements show your assessed value, tax rate, and total amount owed, but they are not the same as a bill from your municipality or county treasurer.
How to search for your property on a county assessor website
Once you are on your county assessor's website, look for a link labeled "Search Records," "Property Search," "Look Up Property," or "Online Records." Click that link to open the search tool.
Enter either your street address (including the city and ZIP code) or your parcel number. The parcel number is a unique identifier assigned to your property; if you do not know it, the address search will usually find it for you. Some systems also accept the owner's name, though address or parcel number is faster and more reliable.
After you search, the system will display basic information about your property: the address, parcel number, owner name, property type, and assessed value. To view the full property tax statement or assessment details, you may need to click on the parcel number or a "Details" button.
What information appears on your statement
A property tax statement in Illinois typically shows the following: your property address and parcel number, the land value and building value (assessed separately), the total assessed value, the tax rate or "multiplier" used in your county, and the total property tax amount owed for that year.
The statement may also list any exemptions applied to your property—for example, a homeowner exemption, senior exemption, or disabled person exemption. These exemptions lower your assessed value and therefore your tax bill. If you believe you should have an exemption but do not see it listed, contact your county assessor's office.
Do not confuse the property tax statement with a tax bill from your county treasurer or municipality. The assessor's office determines the value and the tax rate; the treasurer's office sends you the bill and collects the payment. The two documents may show different amounts because the bill may include other charges or reflect payment deadlines.
Creating an account or logging in
Some Illinois county assessor websites require you to create a free account before viewing detailed property information. Others display basic data without any login. The requirement depends entirely on which county you live in.
If the website asks you to register, you will typically provide an email address and create a password. Some systems send a confirmation email; you may need to click a link in that email before your account is active. After that, you can log in whenever you want to view your property's information.
If you forget your password, most systems have a "Forgot Password" or "Reset Password" link on the login page. Click it, enter your email address, and follow the instructions sent to your inbox. If you cannot reset it yourself, call the county assessor's office and ask them to help you regain access.
What to do if your county does not offer online access
A small number of Illinois counties have not yet built online search tools. If you cannot find an online portal for your county, contact the assessor's office directly by phone or email. Most offices will email or mail you a property tax statement at no cost within a few business days.
When you call or email, have your property address and parcel number ready. If you do not know the parcel number, the address alone is usually enough. Tell the office you need a current property tax statement or assessment information, and ask whether they can email it to you or if you need to pick it up in person.
Some counties also allow you to request a statement through their county website, even if they do not have a full online search tool. Look for a "Contact Us" page or a form labeled "Request Records" or "FOIA Request."
Understanding assessed value versus market value
The value shown on your property tax statement is the assessed value, not what your home would sell for on the open market. Assessed value is typically lower than market value and is used only to calculate property taxes.
Illinois assessors are required to assess property at a percentage of its fair market value. That percentage varies by property type and county. For example, residential property might be assessed at 33 percent of market value, while commercial property might be assessed at 25 percent. The exact rate depends on your county's assessment practices.
If you believe your assessed value is too high compared to similar properties in your area, you have the right to file a formal challenge called an appeal or objection. The deadline to file is usually in the spring, and the process varies by county. Your county assessor's office can explain the appeal process and the deadline for your area.
Frequently Asked Questions
Can I view someone else's property tax statement online?
Yes. Property tax records are public information in Illinois, and most county assessor websites allow anyone to search any property. You do not need to own the property or have permission from the owner to view the assessed value and basic information. However, some counties restrict access to detailed documents or require you to create an account.
Why does my online statement show a different amount than my tax bill?
The assessor's statement shows the assessed value and the tax rate, but the actual bill from the treasurer may include additional charges, credits, or payment terms. The bill also reflects the current year's taxes, while the statement may show the prior year's assessment. Contact your county treasurer if the bill amount does not match what you expected based on the statement.
How often is the property tax statement updated online?
Most county assessor offices update their online records once per year, usually in the spring or early summer when new assessments are finalized. Some counties update more frequently. Check your county assessor's website or call the office to learn when they typically post new information.
What if I cannot find my property on the county website?
Try searching by parcel number instead of address, or vice versa. If neither works, the property may be listed under a different owner's name or address. Call the county assessor's office with your street address and ask them to confirm the parcel number and current owner of record. They can also tell you if there is a delay in updating the online system.
Do I need my property tax statement to pay my taxes?
No. You pay property taxes using the bill sent by your county treasurer, not the statement from the assessor. The bill includes payment instructions, due dates, and where to send your payment. If you lose your bill, contact the treasurer's office to request a new one or to learn how to pay online.
