Understanding your Will County property tax bill
Property tax bills in Will County are issued twice per year, usually in May and September. Each bill covers a six-month period and includes taxes owed to Will County, your school district, park district, and any other local taxing bodies that serve your address. The bill shows the total amount due and the deadline for payment without penalty.
Your property index number (PIN) appears on the bill and is the key to tracking your account. If you lose your bill, you can look up your PIN and account balance on the Will County Assessor's website or by calling the Treasurer's Office. The PIN stays the same for your property even if ownership changes.
Penalties and interest begin to accrue if payment is not received by the deadline shown on your bill. Will County typically allows a grace period before penalties take effect, but the exact dates depend on the tax year. Check your bill for the specific due date and any grace period information.
