Johnson County Property Tax Records

Property taxes in Johnson County are paid in arrears. The bill you pay this year covers the prior year's assessment. Under 35 ILCS 200/, the lien date is January 1. That date sets who owns the parcel and what it is worth for tax purposes. Tax bills split the total owed among each taxing district that covers the parcel. Schools, the county, road districts, and municipalities in Johnson County all get a share of the bill. The rate depends on where the parcel sits within the county.

A parcel in Vienna may carry a different total tax rate than one in a rural township. That gap comes from the mix of taxing bodies that overlap each area. The assessor sets the value. The County Treasurer collects the tax. If you have questions about how much you owe or when a payment is due, the Treasurer handles that side. For questions about the assessed value itself, the assessment office in Vienna is where to go. Knowing how the system splits up is helpful when you read your Johnson County property records.
