How Property Tax Works

Champaign County, Illinois operates under a property tax system that funds essential local services including schools, municipalities, townships, and county operations. Property taxes are levied based on the equalized assessed value (EAV) of real estate, which is calculated at approximately 33.26% of fair market value for the 2025 assessment year. The county follows Illinois' Property Tax Extension Limitation Law (PTELL), which limits increases in property tax extensions.

The effective property tax rate in Champaign County varies significantly by location due to the overlay of multiple taxing districts, including school districts, municipalities, townships, library districts, and other special purpose districts. For 2025, the county is projecting a 15.73% increase in property tax levies, bringing the total proposed corporate and special purpose property taxes to $39,269,200. Actual tax rates for individual properties depend on which taxing districts serve that specific location within the county.

Property owners should note that tax bills reflect assessments from the previous year, and various tax credits are available to qualifying property owners, though most require annual application and are not automatically applied.

Supplemental Tax Bills

Supplemental taxes in Champaign County are additional property tax assessments that occur when there are changes to property ownership, new construction, or significant improvements made to existing properties during the tax year. These taxes are calculated based on the difference between the old assessed value and the new assessed value, prorated for the portion of the tax year the change was in effect.

Common triggers for supplemental taxes include: newly completed construction or major renovations that increase property value, property transfers that result in reassessment, and corrections to previous assessments. The supplemental tax is calculated by applying the same tax rate that applies to the regular property tax bill to the increase in assessed value.

For example, if a property owner completes a $100,000 home addition in March, and the county's effective tax rate is 6.5%, the supplemental tax would be calculated as: ($100,000 × 33.26% assessment ratio × 6.5% tax rate × 10/12 months remaining) = approximately $1,806 in additional taxes for that year.

Escrow & Property Taxes

Most mortgage lenders in Champaign County require property tax escrow accounts for loans with less than 20% down payment. The lender collects 1/12th of the estimated annual property tax bill with each monthly mortgage payment and deposits these funds into an escrow account. Property taxes are typically paid in two installments: the first due June 1st and the second due September 1st (dates may vary slightly each year).

Lenders are required to conduct annual escrow analyses to ensure adequate funds are collected. If property taxes increase significantly, as projected for 2025 with the 15.73% increase, homeowners may see higher monthly escrow payments or receive a bill for escrow shortage. Property owners should verify that their lender is using current tax information, especially after receiving homestead or other tax credits.

Homeowners without escrow accounts are responsible for making direct payments to the Champaign County Treasurer's office by the specified due dates. The county provides online payment options and mailed payment notices, but property owners remain responsible for timely payment regardless of whether they receive a bill.

Frequently Asked Questions

Q: When are property taxes due for tax year 2025? A: The first installment is due June 5, 2025, with the second installment typically due in September. Tax year 2025 assessments will be payable in 2026, with a final due date of February 28, 2026.

Q: What is the General Homestead Exemption and how do I apply? A: The General Homestead Exemption reduces your property's equalized assessed value by up to $10,000 for owner-occupied residences. This is NOT automatic and requires application. Contact the County Assessment Office at (217) 384-3760 or Assessor@co.champaign.il.us for application forms.

Q: Are there additional tax credits available? A: Yes, the Homestead Exemption for Persons with Disabilities provides an additional $2,000 annual reduction in EAV for qualifying disabled homeowners. Senior citizens may qualify for additional credits. All require separate applications and annual renewal.

Q: How does the homestead exemption work with assessment increases? A: The homestead exemption primarily reduces your assessed value by the exemption amount. It does not cap assessment increases like in some other states - your property can still be reassessed at full market value annually.

Q: When are properties reassessed in Champaign County? A: Properties are subject to annual assessment review. The 2025 assessment year reflects properties at 33.26% of market value with a tentative multiplier applied to reach state equalization requirements.
