Primary Responsibilities and Authority
The Cook County Treasurer collects property taxes from approximately 1.8 million parcels throughout the county. This includes residential properties, commercial buildings, and industrial facilities across Chicago and its suburbs. The office processes roughly $13 billion in tax bills during each collection cycle.
Beyond tax collection, the treasurer distributes funds to over 2,000 taxing bodies including school districts, municipalities, park districts, and library systems. The office also manages delinquent tax sales and oversees the annual tax sale process for properties with outstanding obligations. Additionally, the treasurer maintains detailed property tax records and provides taxpayer assistance services.
Property Tax Payment Options and Deadlines
Cook County property owners can pay taxes through multiple channels including online payments, mail, phone, or in-person visits to any of the treasurer's office locations. The office accepts payments via check, money order, credit card, or electronic bank transfer. Online payments processed through the treasurer's website carry a convenience fee of $3.95 for transactions under $10,000.
Property tax bills typically arrive in two installments annually, with first installment due dates in March and second installments due in August. Late payments incur penalties starting at 1.5% per month, accumulating monthly until paid in full. Properties with delinquent taxes exceeding two years become eligible for the annual tax sale process.
Taxpayer Services and Resources
The treasurer's office operates customer service centers in Chicago's downtown area and several suburban locations including Bridgeview, Des Plaines, Markham, Maywood, and Rolling Meadows. These centers provide in-person assistance for property tax inquiries, payment processing, and document requests. Phone support operates Monday through Friday from 8:30 AM to 4:30 PM.
Property owners can access detailed tax information through the treasurer's online portal, including payment history, assessment details, and exemption status. The website also features a property tax lookup tool that provides current and historical tax data for any parcel in Cook County. Senior citizens and disabled veterans may qualify for property tax exemptions administered through the treasurer's office.
Annual Tax Sale Process
Cook County conducts annual tax sales for properties with delinquent taxes, typically held in October at the Daley Center in downtown Chicago. Properties become eligible for tax sale when taxes remain unpaid for two or more years. The 2025 tax sale included approximately 13,000 properties with combined delinquent taxes exceeding $180 million.
Investors can purchase tax liens on delinquent properties, earning annual interest rates up to 18% when property owners eventually pay their back taxes. Property owners maintain redemption rights for up to two years after the tax sale, allowing them to reclaim their property by paying all outstanding taxes plus accrued interest and fees.

The treasurer position appears on the ballot during general elections held every four years in November. Primary elections occur in March for contested races within political parties.
