How Property Tax Works

Coles County, Illinois operates under a property tax system that funds essential local services including schools, county government, municipalities, townships, and special districts. Property taxes are the primary revenue source for these local governmental entities, supporting everything from education and public safety to road maintenance and library services. The county follows Illinois state property tax laws, including the Property Tax Extension Limitation Law (PTELL), which limits the growth of property tax extensions.

The effective property tax rate in Coles County for the 2025 levy year is approximately 1.03650% of assessed value, though actual rates vary significantly by location within the county due to different combinations of special taxing districts. Your specific tax rate depends on which school district, municipality, township, fire protection district, library district, and other special districts serve your property. Property taxes are assessed annually and collected in two installments, with the county serving as the collection agent for all local taxing bodies.

Supplemental Tax Bills

Supplemental property taxes in Coles County are triggered by specific events that change property ownership or value during the tax year. The most common triggers include new construction, property improvements that increase value, or changes in property use or classification. Unlike the regular annual assessment cycle, supplemental taxes are calculated when these events occur and represent the additional tax owed for the remainder of the current tax year.

When supplemental taxes are levied, the county calculates the difference between the new assessed value and the previous assessed value, then applies the appropriate tax rate for the remaining months in the tax year. For example, if a $50,000 addition is completed in March and increases your assessed value by $16,667 (at the one-third assessment ratio), you would owe supplemental taxes on that increase from March through the end of the tax year at your district's composite rate of approximately 1.03650%.

Escrow & Property Taxes

Most mortgage lenders in Coles County require property tax escrow accounts for borrowers with less than 20% down payment or upon borrower request. Your lender collects approximately 1/12 of your estimated annual property tax bill each month along with your mortgage payment. The lender maintains these funds in an escrow account and pays your property taxes directly to Coles County when due on July 3rd and September 3rd each year.

Lenders are required to conduct annual escrow analyses to ensure adequate funds are collected. If property taxes increase significantly due to reassessment or rate changes, your monthly escrow payment may be adjusted, and you may need to pay any shortage over 12 months or in a lump sum. You can verify your current tax amount and payment status through the county's online system at www.colescountyilretax.us. If you pay taxes directly (without escrow), you're responsible for making both installment payments on time to avoid penalties and interest charges.

Frequently Asked Questions

Q: When are property taxes due in Coles County for the current tax year? A: Property taxes for the 2025 levy year are due in two equal installments: July 3, 2025 and September 3, 2025. If the due date falls on a weekend or holiday, payment is due the next business day.

Q: What tax credits are available and do they require application? A: The primary tax benefit is the General Homestead Exemption, which reduces your assessed value by up to $10,000. This REQUIRES APPLICATION with the Coles County Supervisor of Assessments and is not automatic. Other potential exemptions include Senior Citizens Assessment Freeze and Veterans with Disabilities exemption, all requiring separate applications.

Q: How does the Homestead Exemption work? A: The General Homestead Exemption reduces your property's assessed value by up to $10,000, which saves approximately $104 annually at current tax rates. You must occupy the property as your primary residence and file an application. The exemption does not reduce market value but limits assessment increases and reduces the taxable assessed value.

Q: How often are properties reassessed in Coles County? A: Illinois law requires properties to be reassessed every four years, though the county assessor may conduct annual reviews. The most recent countywide reassessment was completed for the 2025 assessment year. You can appeal your assessment to the Coles County Board of Review if you believe it's incorrect.

Q: What are the penalties for late property tax payments? A: Late payments incur interest charges of 1.5% per month on the unpaid balance. If the first installment is paid late, interest accrues from the original due date. Continued non-payment can eventually lead to tax sale proceedings.

Q: Can I pay my property taxes online? A: Yes, you can pay online at www.colescountyilretax.us or by phone at 1-217-292-6625. The county accepts credit cards, debit cards, and electronic checks, though convenience fees may apply for credit card payments.

Q: Why do tax rates vary within Coles County? A: Your tax rate depends on the combination of taxing districts that serve your property, including school district, municipality or township, fire protection district, library district, and other special districts. Different areas of the county are served by different districts with varying rates.

Q: What should I do if I disagree with my property assessment? A: You can appeal your assessment to the Coles County Board of Review, typically between July and September following the assessment. You may present evidence of your property's value, such as recent sales of comparable properties or a professional appraisal. Contact the Board of Review office for specific filing procedures and deadlines.
