How Property Tax Works

Hancock County, Illinois operates under a property tax system that funds essential local services including schools, county government, municipalities, townships, fire protection districts, and other special taxing districts. Property taxes are the primary revenue source for these local governments, supporting everything from education and public safety to road maintenance and library services.

The effective property tax rate in Hancock County varies by location within the county due to the overlay of different taxing districts. While Illinois has a statewide average effective rate of approximately 2.27%, actual rates in Hancock County depend on which municipality, school district, fire district, and other special taxing districts serve your specific property. Property assessments are conducted by the Hancock County Chief County Assessment Office, with assessed values representing approximately one-third of fair market value as required by Illinois law.

Tax bills are mailed annually in late May, with property taxes split into two installments. The system operates on a one-year lag, meaning taxes billed in 2025 are for the 2024 tax year and fund services for the 2025 fiscal year.

Supplemental Tax Bills

Supplemental property taxes in Hancock County are triggered by significant changes to property ownership or improvements that occur after the annual assessment date but before the end of the tax year. Common triggers include new construction completion, major renovations that add significant value, or changes in property use that affect assessment classification.

When a supplemental assessment is issued, it represents the additional tax owed on the increased assessed value for the remaining portion of the tax year. For example, if a $100,000 addition is completed halfway through the tax year, the supplemental tax would be calculated on 50% of the added assessed value (approximately $33,333 in Illinois) multiplied by the applicable tax rate.

Supplemental tax bills are typically mailed within 30-60 days after the assessment is completed and are due within 30 days of mailing. These taxes are separate from your regular annual property tax bill and must be paid in addition to your scheduled installments.

Section 5

Escrow & Property Taxes

Most mortgage lenders in Hancock County require property tax escrow accounts for borrowers with less than 20% down payment, though some lenders mandate escrow regardless of down payment amount. Your lender collects monthly escrow payments equal to your annual property tax divided by 12, plus an additional cushion amount (typically 2 months of payments) as required by federal law.

Property tax bills for 2024 taxes (payable in 2025) are mailed on May 23, 2025, with due dates of June 27, 2025 (first installment) and September 5, 2025 (second installment). Lenders typically pay the first installment in June and the second in September. Your lender should provide annual escrow statements showing tax payments made on your behalf and any account adjustments needed.

If you pay your own property taxes, mark these dates on your calendar and consider setting up automatic payments through the county's online system. Late payments incur penalties and interest charges that begin accruing immediately after the due dates.

Frequently Asked Questions

Q: When are property taxes due in Hancock County? A: For 2024 taxes payable in 2025, the first installment is due June 27, 2025, and the second installment is due September 5, 2025. Tax bills are mailed May 23, 2025.

Q: What tax credits are available and do I need to apply? A: The primary credit is the Homestead Exemption, which reduces your equalized assessed value by up to $10,000. This credit requires annual application and is NOT automatic. Additional credits may be available for seniors, veterans, or disabled persons, all requiring separate applications with specific deadlines.

Q: How does the Homestead Credit work? A: The Homestead Credit doesn't reduce your market value - it caps the annual increase in your assessed value for tax purposes. You must file an application with the Chief County Assessment Office annually. This credit limits assessment growth, providing tax stability for owner-occupied homes.

Q: How often are properties reassessed? A: Illinois law requires annual assessments, but Hancock County may use a cyclical approach where different areas are physically inspected in different years while maintaining annual valuations based on market data and statistical analysis.

Q: What happens if I pay my property taxes late? A: Late payments incur immediate penalties and interest charges. After the second installment due date, unpaid taxes begin accruing interest monthly, and properties can eventually be subject to tax sale proceedings.

Q: Can I pay my property taxes online? A: Contact the Hancock County Treasurer's office to inquire about online payment options, accepted payment methods, and any associated convenience fees for electronic payments.

Q: How do I appeal my property assessment? A: Assessment appeals must be filed with the Hancock County Board of Review within specific deadlines after receiving your assessment notice. Contact the Chief County Assessment Office for appeal forms and procedures.

Q: Do special districts affect my tax rate? A: Yes, your total property tax rate depends on all taxing districts that serve your property, including school districts, fire districts, library districts, and others. Properties in different areas of the county may have significantly different total rates.

Q: What if I disagree with a supplemental tax assessment? A: Supplemental assessments can be appealed using the same process as annual assessments. Contact the assessment office immediately if you believe a supplemental assessment is incorrect, as appeal deadlines are typically short.

Q: Where can I get help with property tax questions? A: Contact the Hancock County Chief County Assessment Office at ccao@hancockcounty-il.gov for assessment and exemption questions, or the County Treasurer's office for payment and billing questions.
