Registration and deposit
All bidders must register with SRI through the Zeus Auction site to participate. SRI and the Conejos County Treasurer then approve each bidder. The bidder completes and electronically signs a W-9 inside the secure auction system, supplying name, address, and Social Security or employer ID number. Registration for the 2025 sale ran October 13 through November 12, 2025, with the county stating no registrations would be allowed after noon on November 12, 2025, so expect a window that opens in mid October and closes the day before the sale. Payment for all winning bids is by ACH debit from the bank account entered during registration, which is the only accepted form of payment, and the county initiates the debit within 24 hours of the close of the last batch. Bidder questions about auction operation go to SRI at 1-800-800-9588.
Bidding is premium style. The county states each parcel "will be sold to the person who bids the highest amount, in excess of said taxes, penalty, interest and costs," under C.R.S. Title 39, Article 11. Premium paid above the lien amount is not returned to the bidder. Redemption interest is set each September 1 under C.R.S. 39-12-103(3); the county published 14 percent for the 2025 sale. Interest begins accruing in November at the rate set after September 1. Certificate holders may endorse later years of delinquent taxes onto the certificate, and three years from the certificate date an unredeemed holder may apply for a Treasurer's Deed. County officials and employees, their immediate family, and their agents may not bid. Note the separate later stage: the public auction of the option for a Treasurer's Deed is held in person at 12987 County Road G.6 / Veterans Blvd., Conejos, CO 81129, with dates and times published in the Known Interested Party notices on the county's Treasurer's Tax Deed page. That in person deed auction is distinct from the annual online tax lien certificate sale. The Tax Lien Sale page also carries an older 2022 sale list link, so use the Treasurer Information Page for the current year's advertised list.

- Run by
- County Treasurer
- Frequency
- on application
- Typical timing
- There is no fixed calendar. A public auction is scheduled only when a certificate holder applies for one, at least three years after the tax lien sale, and the treasurer must hold it between 110 and 125 calendar days after the known interested party notice is first published or mailed.
Registration and deposit
What sells is a certificate of option for treasurer's deed, not the parcel outright. The treasurer may only accept bids above the combined amount owed to the lawful holder plus the treasurer's fees and costs. County officials, county employees acting in their individual capacity, and their immediate family members may not bid. Payment is by cash, cashier's check, bank check, or electronic funds transfer subject to the treasurer's bidding rules. Any overbid goes to junior lienors who filed a notice of intent to redeem and then to the property owner. Confirm the notice, the bidding rules, and the auction venue with the county treasurer.
This Article 11.5 process replaced direct deed issuance on July 1, 2024. Colorado does not hold a routine calendar tax deed sale, so treat this as an occasional, application-driven auction rather than a recurring event.
Over-the-counter (leftover) purchases
Liens that draw no bid are struck off to the county and the treasurer issues the county a certificate of purchase. The county may then assign, sell, or transfer those certificates in the manner, at the times, and on the terms set by resolution of the board of county commissioners, which is how county-held liens are sold between annual auctions. A certificate on property owing more than ten thousand dollars in taxes needs the property tax administrator's approval after published notice. Whether a county maintains a published county-held list, and on what terms, varies. Contact the county treasurer.

Colorado statewide rules
- Redemption
- Redemption may be made at any time before a treasurer's deed is executed, so the practical window runs well past the three-year mark and through the Article 11.5 auction process. The treasurer must hold that public auction between 110 and 125 calendar days after the known interested party notice is first published or mailed, which gives owners and junior lienors a further defined period to pay. A separate rule lets an owner who was under a legal disability when the deed was executed redeem within nine years of the deed being recorded, at 15 percent per year plus the present value of any improvements.
- Deed deposit
- The treasurer may require the applying lawful holder to post a deposit covering the recording fee plus the actual and reasonable cost of administering the auction, and all Article 11.5 fees and costs are chargeable as additional amounts owing under the tax lien. For bidders, the treasurer accepts cash, cashier's check, bank check, or electronic funds transfer subject to the treasurer's bidding rules. The statute sets no fixed bidder deposit percentage, so the deposit terms come from county bidding rules.
- Surplus proceeds
- Any overbid goes first to junior lienors in order of recording priority, measured as of the recording date of the application for public auction, who filed a notice of intent to redeem and whose liens are unredeemed, up to each lien's unpaid amount plus fees and costs. Whatever remains is paid to the property owner. The treasurer must post a public notice about these funds and mail the owner a notice within thirty calendar days of the auction. Unclaimed remaining overbids sit in escrow for six months without interest, then transfer to the state administrator under the Revised Uniform Unclaimed Property Act. An agreement to pay someone to recover an owner's overbid is unenforceable, and inducing one is a class 2 misdemeanor.
A tax deed does not convey marketable title. Most buyers file a quiet title action before they can resell or insure the property. See the due diligence guide.
