Property tax rates by city in Cook County, 2024
For tax year 2024, billed in 2025, the average residential tax at each city's rate in Cook County ran from $3,232 in Lynnwood to $23,476 in Kenilworth. Across all property in the county, the average tax rate was 8.13 per $100 of equalized assessed value, down from 8.27 in 2023.
