How Property Tax Works

Morgan County, Illinois operates under a property tax system that funds essential local services including schools, municipal services, fire protection, libraries, and county operations. Property taxes are assessed annually based on market value, with assessments currently calculated at 34.08% of fair market value using sales data from 2022, 2023, and 2024. The county follows Illinois' Property Tax Extension Limitation Law (PTELL), which limits annual tax increases.

The effective tax rate in Morgan County varies significantly by location within the county due to overlapping special taxing districts such as school districts, fire protection districts, library districts, and municipal boundaries. Property owners should expect their specific tax rate to differ from county averages based on which combination of taxing districts serves their property. Tax bills are typically mailed in May, with payment due dates generally falling in June and September, though exact dates may vary by taxing district.

Pro tip: If you pay through mortgage escrow, your lender splits these payments across your monthly mortgage. If you pay directly, set calendar reminders to avoid late penalties.
Section 4

Supplemental Tax Bills

Supplemental taxes in Morgan County are triggered by significant changes to property that occur after the annual assessment date but before the end of the tax year. The most common triggers include new construction completion, major improvements or additions, and changes in property use classification. When supplemental taxes are assessed, they represent the pro-rated difference between the old assessment and new assessment for the remaining portion of the tax year.

The calculation involves determining the difference between the previous assessed value and the new assessed value, applying the current tax rate to this difference, and pro-rating based on the number of months remaining in the tax year. For example, if a $100,000 home addition is completed in March and increases the assessed value by $34,080 (at 34.08% assessment ratio), with a 4.5% total tax rate, the supplemental tax would be approximately $1,534 ($34,080 × 4.5%) × 75% (9 months remaining) = $1,151 due immediately upon billing.

Escrow & Property Taxes

Most mortgage lenders in Morgan County require property tax escrow accounts for loans with less than 20% down payment, though borrowers may request escrow even with larger down payments. Lenders collect monthly escrow payments equal to one-twelfth of the annual property tax bill, plus insurance premiums. The lender pays property taxes directly to the county treasurer when bills become due.

Morgan County property taxes are typically due in two installments, with payment dates usually in June and September, though specific dates vary by taxing district and will be printed on tax bills mailed in May 2025. Lenders typically pay taxes slightly before the due date to ensure timely payment and avoid penalties. Property owners should verify that their lender has received and paid their tax bills, as ultimate responsibility remains with the property owner even when using escrow services.

Escrow accounts are analyzed annually by lenders, with adjustments made to monthly payments based on actual tax bills and account balances. If property taxes increase significantly, borrowers may face higher monthly payments or may need to pay escrow shortages at the time of analysis.
