How Property Tax Works

Randolph County, Illinois operates on a property tax system that funds essential local services including schools, townships, municipalities, and county operations. Property taxes are collected annually with bills typically mailed in late spring or early summer, featuring two installment payment options. The county follows Illinois state property tax laws, including the Property Tax Extension Limitation Law (PTELL), which governs how much taxing districts can increase their levies annually.

The effective property tax rate in Randolph County averages around 2.27%, though actual rates vary significantly by location within the county depending on which special taxing districts serve your property. These districts may include school districts, fire protection districts, library districts, park districts, and municipal services. Property owners should note that Illinois uses an equalized assessed value (EAV) system, where properties are typically assessed at 33.33% of fair market value for residential properties.

Supplemental Tax Bills

Supplemental property taxes in Randolph County are triggered when property ownership changes hands or when new construction is completed and assessed. When a property is sold, the county assessor may reassess the property based on the sale price, potentially resulting in a supplemental tax bill if the new assessed value exceeds the previous assessment. New construction, additions, or major improvements that increase property value will also generate supplemental assessments.

The supplemental tax is calculated as the difference between the old and new assessed values, multiplied by the applicable tax rate, prorated for the portion of the tax year remaining after the change occurred. For example, if a home's assessed value increases from $100,000 to $120,000 due to a sale in January, and the total tax rate is 2.5%, the annual increase would be $500 ($20,000 × 2.5%). Property owners must complete Form PTAX-203-B (Illinois Real Estate Transfer Declaration Supplemental Form B) during property transfers to report the actual consideration paid.

Escrow & Property Taxes

Most mortgage lenders in Randolph County require borrowers to maintain an escrow account for property tax payments, especially for loans with less than 20% down payment. Lenders collect 1/12th of the estimated annual property tax bill with each monthly mortgage payment, holding these funds in a separate escrow account. When tax bills are due (typically with first installments due 30-45 days after mailing and second installments due after September 1), the lender pays the county directly from your escrow account.

Lenders must provide annual escrow statements showing deposits, payments, and account balances. If property taxes increase due to reassessment or rate changes, your monthly escrow payment may be adjusted accordingly. Property owners should verify that their lender has paid taxes on time by checking with the Randolph County Treasurer's office, as late payment penalties become the property owner's responsibility regardless of escrow arrangements. You can typically access payment records online through the county's website or by contacting the Treasurer's office directly.

Frequently Asked Questions

Q: When are property taxes due for FY 2025-2026? A: Tax bills are mailed annually with two installment options. The first installment is typically due 30-45 days after bills are mailed (usually late June or July), and the second installment is due after September 1st. Exact dates are printed on your tax bill.

Q: What tax credits are available and do I need to apply? A: The General Homestead Credit reduces your equalized assessed value by up to $6,000 and requires application (though renewal may not be required after initial approval). The Senior Citizens Homestead Credit provides an additional $5,000 reduction for qualifying seniors and requires application. All credits must be applied for - they are not automatic.

Q: How does the Homestead Credit work? A: The Homestead Credit doesn't reduce your property's market value. Instead, it reduces your equalized assessed value (EAV) by up to $6,000 for owner-occupied properties. This credit also helps limit assessment increases year-over-year. You must file for this credit initially, but renewal may not be required once approved.

Q: When are properties reassessed? A: Illinois law requires properties to be reassessed at least every four years, though counties may reassess more frequently. Randolph County follows a regular assessment cycle, and property owners are notified when their property is being reassessed with opportunities to appeal.

Q: What happens if I pay late? A: Late payment penalties and interest apply to overdue property taxes. After the tax sale process, property owners have a minimum of two years to redeem delinquent taxes before losing ownership, with possible extensions up to three years at the tax buyer's discretion.

Q: Can I pay property taxes online? A: Contact the Randolph County Treasurer's office to inquire about online payment options and accepted payment methods. Many Illinois counties now offer online payment systems for property taxes.

Q: How do special taxing districts affect my bill? A: Your property tax rate depends on which combination of taxing districts serve your address - school districts, fire protection districts, library districts, park districts, etc. Properties in different areas of Randolph County will have different total tax rates based on these district boundaries.

Q: How do I appeal my property assessment? A: Property assessment appeals must be filed with the Randolph County Board of Review during designated periods, typically after assessment notices are mailed. You'll need to provide evidence supporting your claim that the assessed value is incorrect, such as recent appraisals or comparable property sales.
