Oak Brook taxpayers paid the 22nd largest sum in sales taxes per municipality in April, according to Illinois tax records.

In total, residents paid just over $2.8 million in sales taxes during that month.

Oak Brook ranked 33rd in the Prairie State the month before, with approximately $2 million spent in sales taxes.

The largest share of sales taxes paid by Oak Brook residents in April came from the Municipal Sales Tax.

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.

A 2025 WalletHub study found that Illinois has the highest overall taxes in the U.S., with rates more than 50% higher than the national average. The study estimates that a median household in Illinois pays an effective tax rate of 16.58%, or about $13,099 per year.
