How property taxes work here
Why do rates differ so much between towns?
Your bill is the sum of every overlapping district's levy — schools are usually the biggest — divided across the town's total assessed value. Towns with high home values and lean levies (like Oak Brook) end up with lower effective rates; towns carrying heavier school or municipal levies run higher.
Which western suburb has the lowest property taxes?
Of these towns, Oak Brook is lowest (~1.33% of value), then Burr Ridge (~1.74%) and Hinsdale (~1.75%). Glen Ellyn (~2.35%) and La Grange (~2.31%) sit at the top of the range.
Do exemptions change the number?
Yes — the General Homestead Exemption lowers the taxable value of your primary residence, with extra exemptions for seniors, veterans, and others. The effective rates here already reflect what most owner-occupants actually pay after the standard exemption.
