How Property Tax Works

De Witt County, Illinois operates under a property tax system that funds essential local services including schools, county government operations, townships, and various special districts. Property taxes are the primary revenue source for local governments, with the county serving as the collection point for all taxing jurisdictions within its boundaries.

The property tax rate in De Witt County varies significantly by location due to multiple overlapping taxing districts. For 2025, the estimated countywide rate is $5.20436 per $100 of assessed valuation, though individual properties may face different effective rates depending on their specific school district, municipality, township, and special district combinations. Illinois assesses property at 33.33% of fair market value, and De Witt County applies an equalization factor of 1.0000 for 2025 taxes. Property owners should note that their actual tax burden depends on both the assessed value of their property and the specific combination of taxing districts that serve their location.

Supplemental Tax Bills

Supplemental taxes in De Witt County are additional property tax assessments that occur outside the regular annual billing cycle. These are typically triggered by changes in property ownership, new construction, additions, or improvements that increase a property's assessed value during the tax year. When such changes occur, the county assessor determines the additional tax owed based on the increased assessed value.

For example, if a homeowner completes a $50,000 addition to their home mid-year, the county will assess the improvement and calculate supplemental taxes on the increased value from the date of completion through the end of the tax year. The supplemental tax is calculated using the same tax rate that applies to the property's regular assessment, prorated for the portion of the year the improvement was in place. Property owners receive a separate supplemental tax bill that is due upon receipt, in addition to their regular annual property tax bill.

Escrow & Property Taxes

Most mortgage lenders in De Witt County require borrowers to maintain an escrow account for property taxes, especially for loans with less than 20% down payment. The lender collects monthly payments equal to 1/12 of the annual property tax bill and holds these funds in a dedicated escrow account. When property taxes become due, the lender pays the county directly from the escrow account.

Property tax bills are mailed on February 25th each year, and lenders typically receive and pay these bills promptly to avoid penalties. Property owners should verify that their lender has received the correct tax bill and made payment on time. If you receive a tax bill directly while having an escrow account, forward it to your lender immediately. The lender conducts an annual escrow analysis to ensure adequate funds are collected, and may adjust monthly payments if tax amounts change significantly. Property owners can contact the County Treasurer's office to verify payment status and obtain receipts when needed.
