How Property Tax Works

Bond County, Illinois operates under a property tax system that funds essential local services including schools, county operations, townships, and various special districts. Property taxes are the primary revenue source for these governmental entities, with the Illinois Property Tax Extension Limitation Law (PTELL) providing some limitations on tax increases.

The effective property tax rate in Bond County typically ranges between 1.1% and 1.4% of market value, though this varies significantly based on your property's location within the county due to different combinations of taxing districts. Properties are assessed at approximately 32.91% of market value based on recent sales data from 2022-2024. Your actual tax rate depends on which school district, municipality, township, and special districts serve your property location.

The county utilizes an equalization factor to ensure fair assessment practices, and homeowners may qualify for various tax credits that require separate applications to reduce their tax burden.

Section 4

Supplemental Tax Bills

Supplemental taxes in Bond County are triggered when property undergoes significant changes that affect its assessed value during the tax year. The most common triggers include change of ownership, new construction completion, or major improvements that increase property value.

When supplemental taxes are issued, they represent the difference between what was already assessed and what should have been assessed based on the property changes. The calculation uses the same tax rate as your regular property tax bill, applied to the additional assessed value for the portion of the tax year the change was in effect.

For example, if you complete a $100,000 home addition in July and the county's assessment ratio is 32.91%, the additional assessed value would be approximately $32,910. If your total tax rate is 1.3%, you would owe supplemental taxes of about $428 for the remaining portion of the tax year, prorated from the completion date.

Escrow & Property Taxes

Most mortgage lenders in Bond County require property tax escrow accounts, where you pay 1/12 of your estimated annual property taxes with each monthly mortgage payment. Lenders collect these funds and pay your property taxes directly to the county when due.

Your lender will typically conduct an annual escrow analysis, usually reviewing the account around the anniversary of your loan closing. If property taxes increase or decrease significantly, your monthly escrow payment may be adjusted accordingly. You'll receive advance notice of any changes, typically 60 days before the new payment amount takes effect.

Bond County property tax bills are generally due by late October (with the 2024 bills due October 24, 2024). Lenders usually pay these bills before the due date to avoid penalties. You can verify that your lender has made the payment by checking with the Bond County Treasurer's office or accessing their online payment system. If you pay taxes directly without escrow, you're responsible for ensuring timely payment to avoid interest charges and potential tax sale proceedings.

Frequently Asked Questions

Q: When are Bond County property taxes due for fiscal year 2024? A: Property tax bills for 2024 are due by October 24, 2024. Mobile home tax bills follow the same schedule.

Q: What tax credits are available and do I need to apply? A: The primary credit is the General Homestead Credit, which reduces your equalized assessed value by up to $10,000. This credit requires a separate application and is NOT automatic. You must file the appropriate forms with the Bond County Supervisor of Assessments.

Q: How does the Homestead Credit work? A: The Homestead Credit doesn't reduce your home's market value - it caps the annual increase in your home's assessed value for tax purposes. You must apply for this credit; it doesn't automatically apply to your property.

Q: How often are properties reassessed in Bond County? A: Bond County conducts property reassessments on a cyclical basis. The current assessments are based on market data from 2022-2024 sales. Property owners receive notice of assessment changes and have appeal rights.

Q: What are the penalties for late payment? A: Late payments incur interest charges, and properties with delinquent taxes may eventually be subject to tax sale proceedings. Contact the Bond County Treasurer for specific penalty rates and procedures.

Q: Can I pay my property taxes online? A: Contact the Bond County Treasurer's office to inquire about online payment options and accepted payment methods.

Q: Why do properties in the same county have different tax rates? A: Tax rates vary based on the specific combination of taxing districts (school districts, municipalities, fire districts, etc.) that serve your property location. Two homes of equal value in different parts of Bond County may have different tax bills.

Q: How do I appeal my property assessment? A: Property owners can appeal assessments through the Bond County Board of Review. Appeal deadlines and procedures are typically outlined on assessment notices, and you should contact the County Supervisor of Assessments for specific filing requirements and deadlines.
