How Park County sells delinquent taxes
Tax certificate sale (lien)
- Run by
- Park County Treasurer & Public Trustee
- Frequency
- annual
- Typical timing
- Park County does not post a tax lien sale date on its website. The county's Tax Liens page states only that "Delinquent Real Property Taxes will be advertised once a week for 3 consecutive weeks prior to the annual tax lien sale for the amount of taxes, accrued interest, advertising, and other applicable charges. (Per Statute C.R.S. 39-11-102)." That three week advertising run is the practical advance notice of the sale. The Colorado County Treasurers and Public Trustees Association tax lien sales roster lists Park County with no sale date recorded, while the Colorado counties that do report dates on that roster sell in October and November. Confirm the current year's date directly with the Treasurer's office at 719-836-4334.

Registration and deposit
No online bidder registration process is published for the annual sale, so contact the Treasurer's office at 719-836-4334 for the current year's registration terms. For county-held certificates left over from prior sales, the county directs buyers to call 719-836-4202 or 719-836-4239, complete a W-9, and pay by cash or certified funds, with an assignment fee added to the certificate value. Existing certificate holders can request Investor Portal credentials by calling 719-836-4239.
No online auction platform is confirmed for Park County, so verify the sale format with the Treasurer's office before planning a bid. The county publishes tax lien content across several pages and none of them names an auction vendor, and the statewide treasurers' association roster records no platform for Park County even though it names GovEase, SRI, RealAuction, and Zeus for other Colorado counties. Do not mistake the county's Investor Portal at https://treasurer.parkco.us:8443/treasurer/InvestorPortal/ for the auction: the county describes it as a tool that "allows Tax Lien Investors to access Certificate and Redemption Reports," which is post-sale recordkeeping rather than bidding. The county also warns that endorsement amounts are not accurate until August 1 each year and that endorsements cannot be processed before that date. Liens not sold at the annual sale are held by the county and can be assigned over the counter, and the county calls this a "buyer beware" proposition that carries no legal rights to the property. The county-held lien list is a PDF at https://www.parkcountyco.gov/DocumentCenter/View/441. Third party tax sale listing sites carry Park County pages but none of them is the county's auction system, so treat only the Treasurer's office as authoritative. Fee amounts shown on county pages may lag the state treasurer fee schedule that took effect June 1, 2026, so confirm current fees before budgeting.
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.

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.
