Frequently Asked Questions

How much is property tax on a $400,000 home in Illinois?
At Illinois's average effective rate of 2.07%, a $400,000 home costs roughly the rate × home value per year. Your actual bill depends on your county, school district, and any homestead or senior exemptions. The state-wide median is around $5196 on a typical home worth $251000.
What is the property tax rate in Illinois?
Illinois's average effective property tax rate is 2.07% of home value. This is the state-wide average — individual counties and cities can be significantly higher or lower. The 'effective rate' already accounts for assessment ratios and typical exemptions, so it's a more practical number than the headline mill rate.
How does Illinois compare to other states?
An effective rate of 2.07% places Illinois in a specific tier relative to the national average of about 0.99%. High-tax states like New Jersey (~2.23%) and Illinois (~2.07%) sit at the top, while Hawaii (~0.27%) and Alabama (~0.41%) are at the bottom. Illinois's position reflects local funding for schools and services.
Does Illinois have a homestead exemption?
Most states do, but the details vary widely. Florida offers $50,000; Texas offers $100,000 for school-district taxes; many states have smaller flat exemptions ($10,000-$25,000) for primary residences. Add senior, veteran, and disability exemptions on top where applicable. Apply once with your county assessor — it usually renews automatically.
When are property taxes due in Illinois?
Most states bill annually or semi-annually. Common payment dates are by year-end (Dec 31) or split between two installments (often March/September or April/October). Mortgage holders typically have taxes escrowed and paid by the lender. Check your Illinois tax authority for exact dates and payment options.
