Illinois state tax: Overview

Illinois state taxes are high in some areas and low in others. For example, Illinois has one of the highest sales tax rates in the U.S., but it's also one of the states that don't tax retirement income.

Illinois also has high property taxes when compared with the rest of the country, but there is no personal property tax in the Prairie State.

[Data for this state tax guide was gathered from a number of sources including the Census Bureau, the state’s government website, and the Sales Tax Handbook. Property taxes are cited as a rate percentage rather than the assessed value.]
