In Colorado, the county sells tax lien certificates after just 1 year of missed taxes. The lien buyer can apply for a treasurer's deed after 3 years if you don't pay. Interest rates range from 9-18%, and you will receive a Notice of Application for Treasurer's Deed as a final warning before losing your property.
After a tax lien certificate is sold (November tax lien sale), the lienholder must wait 3 years before applying for a treasurer's deed. You can redeem during that 3-year period by paying all taxes, interest (9-18% depending on circumstances), and fees. You will receive a Notice of Application for Treasurer's Deed, giving you a final window to act.

Surplus Funds Recovery in Colorado
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?
Colorado does not have tax sale overages — the state's tax sale system does not generate surplus funds from property tax foreclosure sales. However, Colorado does have a well-developed framework for mortgage foreclosure surplus funds (called "overbids") governed by Section 38-38-111. Overbids from foreclosure sales are held in escrow for five years, with specific notice requirements and a structured distribution process. Colorado also has detailed finder's fee regulations under Section 38-13-1304, which cap fees at 20-30% depending on timing and impose strict requirements on recovery agreements. This whitepaper provides a comprehensive guide to Colorado's mortgage foreclosure overbid recovery system.
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
Colorado's tax sale process does not produce surplus funds (overages). This is an important distinction for former property owners to understand.
In Colorado, when property taxes become delinquent, the county sells tax lien certificates rather than the property itself. Investors purchase these certificates, which gives them a lien on the property for the amount of taxes owed plus interest. The property owner then has a redemption period to pay off the tax lien. If the owner fails to redeem, the tax lien holder can eventually petition for a tax deed.
Because this process involves the sale of tax liens (at the amount of the delinquent taxes) rather than the auctioning of properties to the highest bidder, there is no opportunity for surplus funds to be generated from tax sales.
If you lost your property due to unpaid property taxes in Colorado, there are no surplus funds to claim from the tax sale process. However, if your property was lost through a mortgage foreclosure, surplus funds (overbids) may exist.
Notably, Colorado has eliminated automatic treasurer's deeds and implemented a follow-up deed sale process with surplus access, providing additional protections for property owners' equity interests.
Your Rights to Surplus Funds
In Colorado, surplus funds from mortgage foreclosures are called "overbids." Under Section 38-38-111, an overbid occurs when a property is sold at a foreclosure sale for more than the total amount owed on the foreclosing lien.
The distribution of overbids follows a specific priority:
1. First, the overbid is applied to any deficiency on the foreclosing holder's bid.
2. Next, upon expiration of all redemption periods (Section 38-38-302), any remaining overbid is paid to junior lienors in order of recording priority — but only to those who have duly filed a notice of intent to redeem and whose liens have not been redeemed.
3. After all qualifying lienors are paid, any remaining overbid is paid to the owner.
Important limitations on who can receive overbid funds:
- A lienor with a lien recorded after the notice of election and demand has no claim to the overbid
- A lienor who did not timely file a notice of intent to redeem has no claim
- A lienor who accepted less than a full redemption has no claim
The term "owner" is specifically defined as the record owner of the property as of the recording date of the notice of election and demand or lis pendens.
Key Statutes
Colorado's overbid recovery system is governed by several interconnected statutes:
- Section 38-38-111: "Treatment of an Overbid." The primary statute for mortgage foreclosure surplus. Key provisions include:
- Subsection (1): Overbid first applied to any deficiency
- Subsection (2): Distribution to junior lienors in recording priority, then to owner
- Subsection (2.5): Public trustee must post notice on website and mail notice to owner within 30 days after redemption periods expire
- Subsection (3): Unclaimed overbids held in escrow for 5 years. Under $25 goes to county general fund; $25 or more transfers to state as unclaimed property.
- Subsection (3)(b): For overbids exceeding $500, publication notice required for four weeks
- Section 38-38-302: Defines redemption periods and related procedures.
- Section 38-13-108.2: "Property Held by Courts and Public Agencies." Intangible property held by government entities that remains unclaimed for more than one year is presumed abandoned — except overbids of $25 or more, which are presumed abandoned after 5 years.
- Section 38-13-1304: "Agreements to Locate Reported Property — Overbids From Foreclosure Sales." Detailed finder's fee regulations specific to overbids.
The Public Trustee's Office is the primary contact for mortgage foreclosure overbids in Colorado.
The U.S. Supreme Court's unanimous ruling in Tyler v. Hennepin County (2023) held that governments cannot keep surplus proceeds from tax sales beyond what is owed, as this violates the Takings Clause of the Fifth Amendment. In response to this ruling and broader reform trends, Colorado has eliminated automatic treasurer's deeds and implemented a follow-up deed sale process with surplus access, further protecting property owners' equity interests.
How to File a Claim
The process for claiming overbids in Colorado:
1. Receive notice: The Public Trustee is required to post information about remaining overbids on their website and to mail notice to the owner at the best available address within 30 days after the expiration of all redemption periods.
2. Contact the Public Trustee's Office: If you believe an overbid may exist from the foreclosure of your property, contact the Public Trustee in the county where the property was located.
3. Establish your identity and entitlement: You will need to prove you are the record owner of the property as of the date the notice of election and demand or lis pendens was recorded, or that you are a qualifying junior lienor.
4. For overbids held by the Public Trustee or County Treasurer: File your claim with the office that holds the funds. For sales held before September 1, 2012, funds were transferred to the County Treasurer. For sales on or after that date, funds are held by the Public Trustee (the "officer").
5. For overbids transferred to the state: If more than five years have passed and the overbid was $25 or more, the funds may have been transferred to the state as unclaimed property. You would then file a claim with the state administrator (State Treasurer).
6. For large overbids ($500+): The Public Trustee or County Treasurer is required to publish a notice for four weeks in a newspaper of general circulation if the overbid has not been claimed within 60 days after redemption periods expire. Watch for these notices.
7. Provide documentation: Prepare identification, proof of ownership, and any relevant foreclosure correspondence.
Deadlines
Colorado has multiple time-based provisions for overbid claims:
- Immediate entitlement: Upon expiration of all redemption periods under Section 38-38-302, the overbid should be distributed to eligible parties.
- 60 days after redemption periods: If the overbid exceeds $500 and remains unclaimed, the holding officer must begin publishing notice.
- 90 days after redemption periods: Unclaimed overbids from pre-September 2012 sales must be transferred by the officer to the County Treasurer.
- Five-year escrow period: Unclaimed overbids are held in escrow for five years from the date of sale. During this period, the holding entity is answerable for the funds to legally entitled persons.
- After five years:
- Overbids under $25: Paid to the county general fund and become county property.
- Overbids of $25 or more: Presumed to be unclaimed property and transferred to the state administrator under the Unclaimed Property Act.
- One year (general government-held property): Under Section 38-13-108.2, intangible property held by government entities is generally presumed abandoned after one year — but overbids of $25+ are specifically exempted and get the full five-year period.
Claimants should act promptly to recover overbids while they are still held at the county level, before they are transferred to the state.
