Questions

What does the Illinois Census property tax indicator mean?

It is 2.01 %: median yearly real estate taxes ($5,298) divided by median home value ($263,300) for owner-occupied homes in the 2020-2024 ACS. It is 114 % above the national ratio and ranks 2nd among the 50 states and DC. It is not a current tax rate.

Which county in Illinois has the highest Census ratio?

Lake County, at 2.58 % (median bill $8,923). The lowest is Hardin County, at 0.96 %. These are ratios of survey medians, not applicable county tax rates.

Can this predict tax on a $300,000 rental in Illinois?

No. A ratio of two survey medians is not a parcel tax rate or the median of individual rates. Ask the property assessor or tax collector for an assessment using the property address, purchase circumstances, exemptions and local levies.

About the data

Census indicator = median real estate taxes paid / median home value for owner-occupied homes. The ratio of two medians is not the median of individual property tax rates. The 2020-2024 survey is historical, excludes rental housing from these measures and carries sampling uncertainty, especially in small counties. It does not provide current levies, reassessment values or a bill for a specific parcel.
