Illinois Property Taxes and Your Mortgage Payment
Illinois has some of the highest property taxes in the country, and they directly affect your monthly payment. Here's how it works and how to plan for it.
If you're buying a home in Illinois, property taxes deserve a spot near the top of your budget — not an afterthought. Illinois consistently ranks among the states with the highest property taxes, and they directly affect what you'll pay every month.
Property taxes are part of your monthly payment
Most mortgages bundle four things into one monthly payment, often abbreviated PITI:
- Principal
- Interest
- Taxes (property taxes)
- Insurance (homeowners insurance)
Lenders typically collect the tax and insurance portions through an escrow account and pay those bills on your behalf when they come due. So a home with higher property taxes has a higher monthly payment — even at the same loan amount and rate as a lower-tax home.
That's why two similar homes can have noticeably different monthly costs. When you compare homes, compare the total payment, not just the price.
Taxes vary a lot by county and town
Illinois property taxes fund local services — schools especially — so rates differ widely by county and municipality. A home in one suburb can carry a very different tax bill than a similar home a few towns over.
When you browse our city pages, remember that the listed price is only part of the story; local tax rates shape the real monthly cost.
How to plan for it
- Estimate the full payment early. Use our mortgage calculator and include taxes and insurance, not just principal and interest.
- Ask about the specific home's tax bill. Listings and county records show recent taxes.
- Look into exemptions. Illinois offers exemptions (such as the homeowner and senior exemptions) that can reduce the taxable value for those who qualify — check with the county assessor.
- Budget for changes. Taxes can change over time, which can adjust your escrow and monthly payment.
