While the population of Oak Brook has increased 3.5% over the past 10 years*, the property tax collected, excluding the referendum to purchase land in 2018 has increased 53.64%.
If we remove the tax levy attributed to our 2019 General Obligation bonds (“referendum bonds”), which passed with a 68% approval rating, then the total tax rate has increased from .1674 in 2000, to .2572 in 2023. This represents a 53.64% increase in the tax rate over a 23-year period. Much of this increase is due to inflation. **
