Illinois Real Estate Transfer Tax

Illinois taxes the privilege of transferring title under 35 ILCS 200/Article 31: the state at $0.50 per $500 or fraction, counties at $0.25 per $500, and home rule municipalities may add their own. Chicago adds $3.75 per $500 generally paid by the buyer and a CTA portion of $1.50 per $500 generally paid by the seller. By custom the seller pays state and county tax, and a PTAX-203 transfer declaration is filed. An existing mortgage the buyer takes subject to is excluded.

Exam tip
'Fifty for the state, a quarter for the county, round up the half-thousands.' Subtract any assumed mortgage first.
Example
A $412,300 sale is 825 units: state tax $412.50 and county tax $206.25. In Chicago, the buyer adds $3,093.75 and the seller $1,237.50 CTA tax.
