The Illinois Department of Revenue (IDOR) has announced that Marshall County has been assigned a tentative 2025 property assessment equalization factor, or “multiplier,” of 1.0000, according to Director David Harris.
The equalization factor ensures that property assessments across Illinois counties are uniform, as required by state law. Equalization is vital because many of Illinois’ 6,600 local taxing districts—such as school, fire protection, and community college districts—span multiple counties. Without equalization, taxpayers owning comparable properties in different counties could face unequal tax obligations.
Under Illinois law, property must be assessed at one-third of its market value. However, farm property is evaluated differently: farm homesites and dwellings are assessed using standard equalization procedures, while farmland and buildings are valued based on productivity standards.
The IDOR determines each county’s factor annually by comparing recent property sales with assessed values over the previous three years. For Marshall County, assessments averaged 33.32% of market value based on sales from 2022 to 2024, aligning closely with the state’s one-third standard. The equalization factor of 1.0000 will apply to 2025 taxes payable in 2026.
Last year’s multiplier for the county was also 1.0000, indicating consistent assessment practices. The tentative factor could change if new data or county-level adjustments significantly affect the results. A public hearing will be scheduled within 20 to 30 days after publication of the tentative factor in a local newspaper.
Officials note that a change in the multiplier does not directly raise or lower tax bills. Tax amounts depend on local taxing districts’ annual revenue requests, not the equalization factor itself. Instead, the multiplier ensures fairness in how each property owner’s share of the total tax burden is calculated.
