How Property Tax Works

Shelby County, Illinois operates under a property tax system that funds essential local services including schools, townships, county operations, and special districts. Property taxes are the primary revenue source for local governments, supporting everything from road maintenance and public safety to education and general assistance programs. The county follows Illinois state law, including the Property Tax Extension Limitation Law (PTELL), which governs how tax levies can increase annually.

Property tax rates in Shelby County vary significantly by location due to the overlapping jurisdictions of school districts, municipalities, townships, and special taxing districts. While the county-specific rate is 0.0035220 (effective July 10, 2025), the total effective tax rate typically ranges from 1.5% to 3.5% of assessed value depending on your specific location and the combination of taxing districts that serve your property. Each township, school district, and municipality adds their own levy to the total tax bill, creating unique rate combinations throughout the county.

Supplemental Tax Bills

Supplemental taxes in Shelby County are additional assessments that occur when there are changes to a property's assessed value outside the regular assessment cycle. Common triggers include new construction, completion of building permits, property improvements that increase value, ownership transfers that prompt reassessment, or corrections to previous assessments.

Supplemental taxes are calculated by applying the current tax rate to the difference between the new assessed value and the previous assessed value, prorated for the portion of the tax year remaining. For example, if you complete a $50,000 home addition in January and it increases your assessed value by $16,667 (at Illinois' one-third assessment ratio), you would owe supplemental taxes on that additional assessed value for the remainder of the tax year. The supplemental bill would be calculated as: $16,667 × (your property's combined tax rate) × (months remaining in tax year ÷ 12). These supplemental assessments are billed separately from your regular property tax bill and have their own due dates.

Escrow & Property Taxes

Most mortgage lenders in Shelby County require property tax escrow accounts to ensure timely payment of property taxes. Your lender collects monthly escrow payments (typically 1/12 of your annual tax bill) along with your mortgage payment, then pays your property taxes directly to the county when they become due. Lenders typically collect an additional 2-3 months of taxes as a cushion to account for potential increases.

Property tax bills are mailed in May for taxes due in two installments: the first installment is due by July 1st, and the second installment is due by September 2nd. If you have an escrow account, verify that your lender has the correct mailing address and is receiving the tax bills. You should receive an annual escrow analysis from your lender showing how your tax payments are managed, and your monthly escrow amount may be adjusted if there are significant changes in your tax bill. If you pay taxes directly without escrow, you can make payments online at www.govtechtaxpro.com through September 2nd, after which payments must be made directly to the County Treasurer's office.
