How Eagle County sells delinquent taxes

- Typical timing
- Annual online sale in November. The Treasurer's tax lien sale page states "The sale will be held online on Wednesday, November 12, 2025" and "The 2025 Tax Lien Sale will be held Wednesday, November 12th on the internet." Registration for that sale opened October 16, 2025, and the page sets the cutoff as "On or before November 5, 2025 at 2 p.m." to register and submit a deposit. The county has not yet posted a specific 2026 sale date; it says the delinquent Real Property and Mobile Home sheets for the 2026 tax lien sale will be available in October 2026, so confirm the current date with the Treasurer's Office.

Registration and deposit
Register online at the RealAuction site before the sale date. Registration includes an IRS W-9 form and acceptance of a User Agreement. Bidders must post a deposit of at least 10 percent of what they plan to spend, submitted by ACH electronic check; final payment after the sale is also drawn by ACH from the banking information on the most recent settled deposit. The 2025 cycle required registration and deposit on or before November 5, 2025 at 2:00 p.m. MT, and the county advised calling the office after that date for other deposit options. RealAuction provides video training sessions through the Training link on the auction site, with bidder support at 877-361-7325 or [email protected].
Bidding is by premium bid. The Treasurer states that all tax liens on real property are sold at the online auction with a premium bid, that premiums are not repaid to the investor, and that premiums earn no redemption interest. Winning bidders pay the total advertised price, which includes the delinquent tax, interest, an advertising fee and a $16 certificate fee, plus any premium. The rate is set annually by the Colorado Banking Commission at nine points above the federal discount rate on September 1; the county lists 14 percent for the 2025 sale. Real estate, mobile home and special assessment parcels are offered, and special assessment liens sell with the corresponding real estate lien when both are delinquent. The list is advertised for three consecutive weeks before the sale in the Vail Daily and Aspen Daily News, posted to the Treasurer's tax lien sale page in early October and updated weekly; a preliminary list also appears on the auction site in October and is updated through the morning of the sale. Certificates of purchase are held in safekeeping by the Treasurer and stay valid for 15 years. Investors may apply for a public auction three years after the sale date, which requires an $800 deposit handled through the Treasurer's Office. Liens not sold at the sale are held by the county and are in some cases available for purchase through the Treasurer's Office, generally low-value parcels such as unbuildable strips or open space. Certificate holders may endorse the following year's unpaid taxes onto an existing certificate after August 1 at the same rate. Treasurer's deed auctions are a separate process, also administered by RealAuction on its own site, and are not part of this certificate sale.
Register on RealAuctionTax deed sale
- 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.

- Eagle County runs its tax lien sale entirely online through RealAuction at eagle.coloradotaxsale.com; there is no in-person courthouse bidding.
- Registration and the deposit close about a week before the sale, so investors should register as soon as the delinquent list posts in October to allow time for research.
- Premium bids are not returned and earn no interest, so the effective yield falls as the premium rises above the advertised amount.

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.
