How Property Tax Works

Jackson County, Illinois operates under the state's property tax system to fund essential local services including schools, municipal services, fire protection, and county operations. Property taxes are the primary revenue source for these local government entities and special districts throughout the county. The Illinois Property Tax Extension Limitation Law (PTELL) governs how tax levies can increase annually, providing some protection against dramatic tax increases.

Property tax rates in Jackson County vary significantly by location within the county due to overlapping special taxing districts including school districts, municipalities, townships, fire protection districts, and other local entities. For the 2025 tax year, Jackson County is experiencing changes due to a legal settlement affecting property tax recapture, and a tentative property assessment equalization factor of 0.9800 has been set. Property owners should note that their specific tax rate depends on which combination of taxing districts serve their property location.

The county follows Illinois' standard assessment and payment schedule, with property taxes typically due in two installments on June 1 and September 1. Due to significantly higher 2024 tax bills (some up to 50% higher), the county has provided an additional 60-day grace period for payments without penalties to help property owners adjust to the increased assessments.

Section 2

Section 4

Supplemental Tax Bills

Supplemental taxes in Jackson County are additional property tax assessments that occur when there are changes to property ownership or improvements made to existing properties outside the normal assessment cycle. These taxes ensure that new construction, major renovations, or ownership transfers are properly reflected in the current tax year rather than waiting for the next regular assessment period.

Supplemental taxes are typically triggered by new construction completion, substantial property improvements that increase assessed value, or certain types of ownership changes. The supplemental tax is calculated as the difference between the old assessment and new assessment, multiplied by the applicable tax rate, prorated for the portion of the tax year remaining after the change occurs.

For example, if a property owner completes a $100,000 home addition in March, and the addition increases the assessed value by $33,000 (at Illinois' one-third assessment ratio), the supplemental tax would be calculated on that $33,000 increase for the remaining 9 months of the tax year. The county assessor's office reviews building permits and other records to identify properties subject to supplemental assessment.

Escrow & Property Taxes

Most homeowners with mortgages in Jackson County have their property taxes collected through escrow accounts managed by their mortgage servicer. Lenders collect monthly escrow payments along with principal and interest, then pay property taxes directly to the county on the homeowner's behalf when bills are due.

Jackson County property taxes are typically due in two installments: June 1 and September 1. Mortgage servicers usually make these payments shortly before the due dates to ensure timely payment and avoid penalties. Property owners should verify that their lender has current mailing addresses and contact information with the county treasurer's office to ensure tax bills and notices are properly delivered.

Escrow accounts are analyzed annually by lenders to ensure adequate funds are collected. Given the recent significant increases in Jackson County property taxes (some bills up 50% higher in 2024), many property owners may experience escrow shortages requiring increased monthly payments or lump-sum payments to cover deficits. Property owners should review their annual escrow analysis statements carefully and budget for potential payment increases. Those without escrow accounts are responsible for making direct payments to the Jackson County Treasurer by the specified due dates.
