Registration and deposit
Registration is online through the RealAuction site at mesa.coloradotaxsale.com. The Treasurer states "All bidders will be required to complete a registration process online, as well as a deposit process in order to participate in the sale." Returning bidders who already registered for a prior Mesa County online sale do not have to register again, but should confirm their registration details are current. Every bidder must post a deposit equal to ten percent of the total dollar amount of tax certificates the bidder anticipates winning. Deposits are accepted by ACH only through RealAuction's website and must clear by 2:00 p.m. on the deposit due date. Personal checks and cash are not accepted. If a bidder's deposit falls below ten percent of certificates won plus active bids, those bids may not be accepted. Questions go to RealAuction at 1-877-361-7325 or the Mesa County Treasurer at 970-244-1824.
Mesa County sells tax lien certificates online, not deeds. The county page is explicit: "You purchase the tax lien, NOT the property! In Mesa County, eventual transfer of deed has occurred in less than one percent of all purchases." Bidding is premium bidding. The minimum starting bid equals unpaid taxes, interest, penalties and fees, bid increments are one dollar, and premium bidding is at the bidder's discretion up to 30 percent. Bidding above 30 percent triggers a warning that the bidder can pass. Premiums are a cost of securing the lien, are not refunded, and do not draw interest. The sale runs in timed batches of roughly 200 properties each, closing in one hour increments on sale day starting at 9:00 a.m. Mountain time through 2:00 p.m., with a final auxiliary batch closing at 5:00 p.m. if properties remain. Once a batch closes, bids are final and cannot be changed or withdrawn. Results are posted by bidder number. Accounts can be redeemed by the owner and drop off the list up until the day before the sale. The Treasurer states the rate for the current sale year is 15 percent, set by the Colorado Banking Commission at nine percentage points above the federal discount rate as of September 1 and updated each September. Certificate holders may endorse subsequent unpaid years onto the original certificate after August 1 each year at the same guaranteed rate; holders who decline to endorse will see the Treasurer offer that later lien to another bidder, which can complicate a future deed application because junior lien holders may be involved. Mesa County employees and officials, their immediate families and their agents may not acquire a lien at the sale under C.R.S. 39-11-151. The county cites C.R.S. 39-11-101 through 39-12-113 as the governing authority. The property list is published before each sale through the Daily Sentinel public notice site, linked from the Treasurer's Tax Lien Sale Publications page; the most recent publication posted there is the 2025 list with a publication date of September 20, 2025, so check that page for the current year's notice as the sale approaches. Training video dates for the auction platform were not yet posted at the time of review. Verify all dates and requirements with the Treasurer's Office before bidding.
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.

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.
