In Illinois, municipal sales taxes, usually set at 1%, are added to the state sales tax of 5% and a county tax of 0.25%, resulting in a combined state tax rate of 6.25%. These taxes can vary locally and are used to address municipal needs such as infrastructure, public services, and community development. The revenue generated is destined to fund local government operations, public safety, education, and other community projects.
