Cook County Property Tax Bills Delayed Until December 2025

Why This Matters: The delay in property tax bills adds financial stress for Cook County residents during the holiday season. It disrupts budgeting and creates uncertainty for families.

The Cook County property tax delay stems from a complex technology upgrade contracted to Tyler Technologies in 2015. The goal was to modernize the property tax billing system, but the project has faced significant delays. The county awarded Tyler Technologies two contracts totaling nearly $87 million. The company’s business license was briefly revoked due to a failure to file an annual report. The integrated system aims to consolidate three county agencies using different legacy systems and convert 20 years of data. This delay is not the first instance, as similar delays occurred in 2022. This situation highlights the challenges of large-scale technology implementations in government and the impact on taxpayers.

The delay is due to a years-long technology upgrade of the Cook County property tax system.

The delayed property tax bills are due on December 15, 2025.

Interest will not accrue until after the due date passes.

The county initiated a Bridge Loan Program to provide no-interest loans to local taxing jurisdictions.
