In Illinois, the county sells tax lien certificates after 1 year of unpaid taxes. You have between 2 and 3 years to redeem your property by paying off the lien buyer plus interest before losing your home. The tax sale process goes through the court system, providing oversight and notice protections.
Illinois sells tax lien certificates at annual tax sales. For residential properties (6 units or fewer), you have 2 years and 6 months from the date of the tax sale to redeem. For all other properties, the redemption period is 2 years. You must pay the tax buyer the purchase price plus penalties (up to 36% for the first 6 months, increasing after). The tax buyer will serve you a 'take notice' before seeking a tax deed.

Surplus Funds Recovery in Illinois
When a property sells at foreclosure — tax or mortgage — for more than what is owed, the excess money — called surplus funds — may belong to the former owner. Following the landmark Tyler v. Hennepin County (2023) Supreme Court decision, your constitutional rights to these funds are stronger than ever.
What Are Surplus Funds?
Illinois does not have tax sale overages in the traditional sense. The state uses a tax lien certificate system rather than a tax deed foreclosure sale that generates surplus funds. As a result, Illinois is not a recommended state for tax foreclosure surplus fund recovery. However, Illinois does have mortgage foreclosure surpluses, and former homeowners have the right to petition the court for any excess money resulting from a mortgage foreclosure sale. This guide explains Illinois's unique tax sale system, the limited surplus fund opportunities that exist, and the mortgage foreclosure surplus process that may be relevant to some property owners. Understanding the distinction between tax sale and mortgage foreclosure surplus is critical for anyone seeking to recover funds in Illinois.
Note: This guide reflects information current as of April 2026. Tax foreclosure laws are actively evolving following the landmark Tyler v. Hennepin County Supreme Court decision (2023). Always verify current statutes and consult with a licensed attorney before taking action.
How Tax Sales Work
Illinois uses a tax lien certificate system rather than a traditional tax deed sale. When property taxes become delinquent, the county sells a tax lien certificate to an investor rather than selling the property itself. The investor pays the delinquent taxes and receives a certificate entitling them to interest on their investment. The property owner retains ownership and has a redemption period to pay back the investor with interest.
If the property owner fails to redeem during the statutory period, the tax lien certificate holder can petition the court for a tax deed, which transfers ownership of the property. Because the county is selling a lien certificate -- not the property itself -- there is typically no auction that would generate a sale price above the tax debt. This is why Illinois does not produce tax sale overages.
This system fundamentally differs from states where properties are sold at auction to the highest bidder. In those states, competitive bidding can drive the sale price well above the tax debt, creating surplus funds. In Illinois, the certificate sale process simply does not create that opportunity.
It is worth noting that while the tax lien certificate system does not generate surplus in the same way as a deed sale, the process can still result in significant financial consequences for property owners. When a certificate holder eventually obtains a tax deed, the property owner loses their home without any competitive auction process that might capture the property's true market value. This means that in many cases, the property owner loses equity in the property without any opportunity to recover the difference between the property's market value and the tax debt. Understanding this dynamic is important for property owners facing tax delinquency in Illinois, as it underscores the importance of redeeming the property during the statutory period.
Your Rights to Surplus Funds
Since Illinois does not generate tax sale surplus funds, this section focuses on the mortgage foreclosure context where surplus funds can and do arise.
Under Illinois law, when a property is sold at a mortgage foreclosure sale for more than the amount owed on the mortgage plus costs, the excess constitutes surplus funds. Illinois Section 15-1504.5 requires that a Homeowner Notice be attached to the foreclosure summons, which explicitly informs homeowners of their rights, including: the right to live in the home until a judge enters a possession order; the right to reinstate the mortgage within 90 days; the right to redeem the property during the redemption period; and critically, the right to petition the court for any excess money that results from a foreclosure sale.
The former homeowner (mortgagor) is the primary party entitled to mortgage foreclosure surplus funds, followed by junior lienholders in order of priority.
Key Statutes
Key Illinois statutes relevant to surplus funds include:
- Illinois does not have a specific tax sale surplus statute because the tax lien certificate system does not generate surpluses.
- 735 ILCS 5/15-1504.5 (Homeowner Notice): Requires attachment of a notice to foreclosure summons informing homeowners of their rights, including the right to petition the court for excess money from a foreclosure sale.
- 765 ILCS 1025 (Uniform Disposition of Unclaimed Property Act), Section 8: Establishes that all funds and intangible personal property held for the owner by any court, public authority, or public officer that has remained unclaimed for more than seven years is presumed abandoned. This seven-year period applies to mortgage foreclosure surplus funds held by the court.
The seven-year window before funds are presumed abandoned provides a relatively generous timeline for claimants compared to many other states.
In Tyler v. Hennepin County (2023), the U.S. Supreme Court ruled unanimously that governments cannot keep surplus proceeds from tax sales beyond what is owed, finding this violates the Takings Clause of the Fifth Amendment. This landmark ruling has strengthened property owners' rights to surplus funds nationwide.
How to File a Claim
For mortgage foreclosure surplus funds in Illinois:
1. Identify the Court: Mortgage foreclosure surplus funds are held by the Clerk of the court that handled the foreclosure proceeding. This is typically the Circuit Court in the county where the property is located.
2. Research Your Case: Obtain the case number and review the court file to determine whether surplus funds exist from the foreclosure sale.
3. Petition the Court: File a petition with the court requesting distribution of surplus funds. The petition should establish your identity, your interest in the property, and the amount of surplus funds you are claiming.
4. Provide Documentation: You will need to submit proof of identity, documentation of your ownership interest or lien position, and any other evidence the court requires.
5. Court Review: The court will review the petition and may schedule a hearing. If the claim is approved, the court will order distribution of the funds.
The Clerk's office is the primary contact for mortgage foreclosure surplus funds in Illinois. Be prepared for the process to involve more formal court procedures than a simple administrative claim.
It is important to note that the mortgage foreclosure surplus claim process in Illinois is a court proceeding, which means it involves more formal procedures than a simple administrative claim. The court has discretion in how it handles surplus distribution, and competing claims from junior lienholders or other parties may need to be resolved before the former homeowner receives their funds. Hiring an attorney or working with a mission-driven company experienced in foreclosure surplus claims can significantly streamline the process.
Deadlines
Key deadlines in Illinois:
- Tax Sale: Not applicable -- Illinois does not generate tax sale surplus funds.
- Mortgage Foreclosure Surplus: Under the Uniform Disposition of Unclaimed Property Act (765 ILCS 1025, Section 8), funds held by a court or public officer are presumed abandoned after seven years. This means claimants have up to seven years to claim mortgage foreclosure surplus funds before they are transferred to the state as unclaimed property.
- Post-Abandonment: Once funds are presumed abandoned and transferred to the state, they may still be claimable under Illinois's unclaimed property procedures, though additional restrictions and requirements may apply.
The seven-year window is one of the longer periods available among U.S. states, but claimants should not wait. Filing a claim as soon as possible after the foreclosure sale reduces the risk of complications and ensures the funds are still readily accessible.
