Real Estate Tax Calculation Examples

Let's look at two examples to illustrate how the calculator works:

Example 1: Residential Property in Cook County

For a $250,000 residential property in Cook County:

State tax rate: 2%
Cook County tax rate: 1.5%
Special district tax rate: 0.5%

Calculation: ($250,000 × 0.02) + ($250,000 × 0.015) + ($250,000 × 0.005) = $5,000 + $3,750 + $1,250 = $9,000 annual property tax

Example 2: Commercial Property in Will County

For a $500,000 commercial property in Will County:

State tax rate: 2%
Will County tax rate: 1.2%
Special district tax rate: 0.8%

Calculation: ($500,000 × 0.02) + ($500,000 × 0.012) + ($500,000 × 0.008) = $10,000 + $6,000 + $4,000 = $20,000 annual property tax
