Cook County Voters Approve $338M in Tax Hikes Despite Record-Low Turnout — Cook County Treasurer's Office

Event summary

Only 20.1% of Cook County voters participated in property tax referendums during the 2025 local elections and 2026 primary election.
Voters approved 15 of 20 binding property tax referendums, enabling $335.5M in new bonds and $3.5M in direct tax increases.
Lowest turnout (4.9%) occurred for Northbrook Rural Fire Protection District's $425K tax increase, affecting homeowners with an annual $106.26 hike.
Highest turnout (40.6%) was in Oak Park, where voters rejected a $40M bond proposal for an indoor aquatics center by 4-to-1 margin.

The big picture

Cook County's dismal voter turnout during property tax referendums highlights a growing disconnect between taxpayer sentiment and actual governance participation. While homeowners vocally protest rising taxes, the lack of ballot-box engagement allows small voter blocs to approve significant financial commitments. This trend raises questions about the sustainability of local government funding models and the democratic validity of tax policy decisions.
