How Property Tax Works

Lawrence County, Illinois operates under the state's property tax system to fund essential local services including schools, county government operations, townships, and various special districts. Property taxes are assessed annually based on market value and collected in two installments, with the current assessment rate at 35.17% of fair market value. The county follows Illinois Property Tax Extension Limitation Law (PTELL) guidelines and uses a three-year sales analysis period (2021-2023) to determine assessments.

The effective tax rate varies significantly by location within Lawrence County due to different combinations of taxing districts, including school districts, municipalities, townships, fire protection districts, and other special service areas. Property owners may be eligible for various tax credits that require application and can substantially reduce their tax liability. The county's equalization factor for recent years has been 1.0000, meaning local assessments align with state standards.

Supplemental Tax Bills

Supplemental taxes in Lawrence County are typically triggered by new construction, property improvements, or changes in property ownership that result in reassessment during the tax year. When improvements are made to a property, the Supervisor of Assessments may issue a supplemental assessment to capture the increased value for the current tax year rather than waiting for the next regular assessment cycle.

The supplemental tax is calculated by taking the difference between the new assessed value and the original assessed value, multiplying by the applicable tax rate for that location. For example, if a property owner adds a $50,000 addition to their home mid-year, and the assessment increases by $17,585 (35.17% of $50,000), they would receive a supplemental tax bill for the additional amount prorated for the remaining months of the tax year.

Escrow & Property Taxes

Most mortgage lenders in Lawrence County require borrowers to maintain an escrow account for property taxes and insurance. The lender collects monthly payments equal to 1/12th of the estimated annual tax bill and pays the county directly when taxes are due. Given Lawrence County's bi-annual payment schedule (June 1 and August 1), lenders typically make two payments per year to the County Collector.

Property owners should verify their escrow account balances annually and ensure their lender has current tax information. The County Collector's office can provide tax amounts and due dates to mortgage companies. If you pay taxes directly rather than through escrow, you're responsible for making payments by the June 1 and August 1 deadlines. Contact the County Clerk at (618) 943-2346 to update your mailing address for tax bills or to verify payment information.
