Property in St. Clair County gets assessed at 33.33% of fair market value. A home worth $120,000 would have an assessed value of about $40,000. The Illinois Department of Revenue then applies a multiplier to equalize values across townships. That gives you the equalized assessed value. Tax rates from local districts get applied to the EAV to produce the final bill. Exemptions lower the EAV before the rate is applied, so they can make a real difference on your St. Clair County property tax bill.

St. Clair County provides a Senior Homestead Exemption worth up to $5,000 off the EAV. There is also a Senior Assessment Freeze for homeowners with household income of $65,000 or less.

These details are all part of your St. Clair County property tax records and appear when you search a parcel.
