# Cook County Proposes $18M Tyler Renewal

Cook County is proposing a two-year extension of Tyler Technologies’ support and maintenance contract for its Integrated Property Tax System, worth up to **$18 million**, with County Board approval expected next month. The extension would continue support through early 2029 despite unresolved billing, refund, and data-conversion issues; payment holdbacks are tied to resolving defects. The county has also approved restrictions on contractors sharing county-held personal information with third parties or using it for federal immigration enforcement.

- The proposed renewal is a significant incumbent opportunity, but its approval remains pending. The county’s stated dependence on Tyler and limited alternatives may shape competition for future property-tax system work.
- Contractors should account for defect resolution, payment holdbacks, and stronger oversight when assessing performance and delivery risks under the proposed extension.
- Companies handling Cook County data should evaluate the approved restrictions on third-party sharing and use of personal information, including for federal immigration enforcement.
