Registration and deposit

Bidders register with the auction provider, not the county. The Treasurer's procedures state: "ALL BIDDERS MUST REGISTER WITH THE AUCTION PROVIDER, SRI INC., IN ORDER TO PARTICIPATE IN THE 2025 TAX LIEN SALE. Registration will begin on September 18, 2025 and will continue through October 01, 2025. Information for registration with SRI Inc. can be found on their web site: www.zeusauction.com." Each participant must complete the Declaration of Statutory Compliance, a W-9 form, and the SRI registration form. Certificates of purchase and redemption checks are issued in the name shown on the W-9. Registrations were not accepted after 4:30 p.m. Mountain time on the closing date. The Treasurer posts the W-9, Declaration of Immediate Family, assignment worksheet, buyer beware notice, and withdrawal form on its Taxbuyer Documents page. Registration windows shift each year, so verify the current dates before the sale.

Pueblo County runs a premium bid internet auction. Every parcel is offered under C.R.S. Title 39, Article 11, and each lien is "sold to the person who bids the highest amount, in excess of said taxes, penalty, interest, and costs." The Treasurer states plainly that "Premium bids are not returned to the bidder," so premium paid above the lien amount earns nothing and is not refunded at redemption. Redemption interest is set each September 1 under C.R.S. 39-12-103(3); the rate applied to the most recent published sale was 14 percent, and interest begins accruing in October. Liens wrongfully sold earn 8 percent per annum. A certificate holder may endorse (pay) later years' delinquent taxes, and after three years an unredeemed certificate holder may apply to the Treasurer for a treasurer's deed. County officials, county employees, their immediate family and agents, and assessed owners of the subject property may not bid. The Treasurer and the auction provider hold a pre-sale seminar in the County Commissioners' Chamber at 215 W. 10th St, and public computer stations are available at the Treasurer's Office during business hours through the sale period. The delinquent list is advertised in the Pueblo Chieftain for three consecutive weeks ahead of the sale and posted as a PDF on the county's tax lien sale page. Separately, the Treasurer runs treasurer's deed auctions and maintains a county held property list; the deed auction bidding rules and fees were revised, and the county links the updated rules from its Treasurer pages.

Tax 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.

Notes for Pueblo County

The Treasurer's Office is on the first floor of the Pueblo County Historical Courthouse at 215 W. 10th Street, Pueblo, CO 81003. Office hours are 8:00 a.m. to 4:30 p.m. Monday through Friday except holidays. The tax lien sale counter is Room 104.
Tax lien sale matters are handled by the Redemption Department. The county lists (719) 583-6689, (719) 583-6528, and (719) 583-6015 for that department, and the sale notice adds (719) 583-6017 for delinquent tax questions. The main Treasurer line is 719-583-6015 and the fax is 719-583-6526.
The elected Treasurer is Kimberly Archuletta, who signs the tax lien sale procedures.
To avoid a lien being sold, delinquent taxes had to reach the Treasurer's Office in cash or certified funds by 4:30 p.m. about one week before the auction. Redemption payments opened roughly three weeks after the sale closed.
The county's tax lien sale page still carries the prior year's sale information as of late July 2026. Treat the October window as the pattern and confirm the exact dates, registration window, and interest rate with the Treasurer's Office once the current year's notice is published.
The county also maintains a county held property list and separate treasurer's deed auctions, both linked from the Treasurer's Office home page. Those are distinct from the annual certificate sale.

Colorado statewide rules

Max interest rate: 14% per year, set by statute (bidding is on price)
Minimum return: No statutory minimum return; what you earn is set by the price at the sale
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.
Governing statute: C.R.S. Title 39, Article 11

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.
