Property Search Tool FAQs
What is the Arlington Heights County Property Search Tool?
The Property Search Tool is a web‑based portal that lets anyone enter an address, owner name, or parcel ID to view detailed information. The interface displays the parcel’s legal description, assessed value, tax year, and a clickable map layer that outlines the property boundary. Data comes directly from the county’s GIS database, which is refreshed after each assessment cycle.
Is the Property Search Tool free to use?
Yes. The portal is publicly accessible at www.arlingtonheightsil.gov. No registration, fee, or software download is required. All GIS layers, including aerial imagery and cadastral maps, are provided at no cost.
How often is the Arlington Heights County property database updated?
The core parcel dataset is refreshed annually after the assessor finalizes the tax roll. Supplemental layers—such as recent building permits or zoning changes—are added within 30 days of receipt. Users can see the “Last Updated” timestamp on the map legend.
Can I search using only part of an address or owner’s name?
Partial searches work for both fields. Typing “Maple” will return every parcel on Maple Street, while “Smith” brings up every record containing “Smith” in the owner name. The tool uses wildcard matching, so spelling variations are also captured.
What should I do if I can’t find my property in the search results?
First, verify the spelling of the address or parcel ID. If the issue persists, the parcel may be under a recent reassessment that has not yet been uploaded. In that case, contact the Assessor’s Office for confirmation.

Online Tax Estimator FAQs
What is the Arlington Heights County Property Tax Estimator Tool?
The Tax Estimator calculates the projected annual tax bill for a selected parcel. Users input the parcel ID or address, and the system applies the current millage rates for school, township, and special districts. Results include a breakdown of each levy and the total amount due.
Can I use the Tax Estimator for any property in Arlington Heights County?
The estimator works for all residential, commercial, and industrial parcels within the village limits. Agricultural land outside the municipal boundary is excluded because it falls under Cook County’s separate tax schedule.
Does the estimator show the exact tax amount due?
The tool provides an estimate based on the most recent assessment and levy rates. Final taxes may differ if exemptions are applied after the estimate is generated. For the official bill, consult the annual tax statement mailed in October.
Can I compare tax estimates from previous years?
Yes. The estimator includes a “Historical View” button that pulls data from the past three assessment cycles. Users can see how changes in assessed value or millage rates affect the total tax.
Arlington Heights County Tax Roll FAQs
What is the property tax roll?
The tax roll is a compiled list of every taxable parcel, its assessed value, and the corresponding tax liability for a given fiscal year. It serves as the legal basis for billing and collection.
Who is responsible for preparing the tax roll?
The County Assessor prepares the roll, while the Treasurer’s Office finalizes billing. Both offices coordinate to ensure that exemptions and abatements are reflected before the roll is published.
When is the Arlington Heights County tax roll finalized each year?
Finalization occurs in early August, after the assessor’s review of appeals and the Treasurer’s verification of levy rates. The completed roll is posted on the assessor’s website by the first week of September.
Can I access previous years’ tax rolls?
All historic rolls are archived in PDF format on the official website. Users can download the 2022, 2021, and 2020 rolls from the “Tax Roll Archive” section.
Why accessing past tax rolls matters
Reviewing historic rolls helps owners track assessment trends, identify potential errors, and prepare for future appeals. Investors also use past rolls to gauge market appreciation.
