If property taxes go unpaid in Illinois

How it works. County tax sale of lien/certificate followed by circuit-court petition for tax deed

Excess sale money. Effective 2026 amendments create a surplus-equity fund. A former owner who loses property by issuance of a tax deed may seek an award based on property value less liens under 35 ILCS 200/21-302, subject to statutory rules

These rules are set by Illinois, not by Cairo, so this section is the same for every place in the state. Last verified 2026-09-25. See the full Illinois entry with statute links.
