How Property Tax Works

Saline County, Illinois operates under the state's property tax system, which funds essential local services including schools, townships, municipalities, fire protection districts, and county operations. Property taxes are the primary revenue source for these local government entities, with tax bills reflecting the combined levy rates of all applicable taxing districts where your property is located.

The effective tax rate for Saline County is approximately $1.8897 per $100 of assessed value as of 2025, though actual rates vary significantly by location within the county depending on which special taxing districts serve your property. Illinois assesses residential property at 33.33% of fair market value, and property owners may qualify for various tax credits that require separate applications to reduce their final tax bill.

Supplemental Tax Bills

Supplemental taxes in Saline County are triggered by changes in property ownership, new construction, or improvements that increase a property's assessed value during the tax year. When these events occur, the county assessor determines the additional assessed value and applies the current tax rate to calculate the supplemental tax owed.

For example, if you purchase a home in March that was previously assessed at $80,000 but now has a market value requiring a $120,000 assessment, you would owe supplemental taxes on the $40,000 increase in assessed value (at 33.33% assessment ratio = $13,333 additional EAV × applicable tax rate) for the remaining months of that tax year. Supplemental tax bills are issued separately from regular annual tax bills and have their own due dates.

Escrow & Property Taxes

Most mortgage lenders in Saline County require property tax escrow accounts, collecting monthly payments equal to 1/12 of your annual tax bill plus insurance premiums. Lenders typically collect 2-3 months of additional reserves at closing to ensure sufficient funds for payment dates.

The Saline County Treasurer sends tax bills annually with two installment due dates, usually in October and November, though the first half of 2025 property taxes are due by December 20, 2025. Your mortgage servicer will pay these bills directly from your escrow account and provide you with copies. You should verify that payments are made timely and review your annual escrow analysis statement to understand any changes in monthly payments due to tax rate adjustments or assessment changes.
