Annually in early November, held online over several days. The 2026 sale "will begin on Monday, November 2, 2026 at 8:00 am (MST)" and closes in batches starting at 1:00 pm Mountain Time on Wednesday, November 4, 2026. Property owners may pay their delinquent advertised taxes until 3:00 pm MST on Wednesday, October 28, 2026, and the payment must be received in the Treasurer's office by then. Delinquent real property taxes are advertised once a week for 3 consecutive weeks before the annual sale (C.R.S. 39-11-102).
Registration and deposit

Register online through ZeusAuction.com. For the 2026 sale, registration opens October 9, 2026 at 8:00 am and closes October 28, 2026 at 11:59 pm, and every bidder must register before October 28. Registration includes an IRS W-9 form and an ACH authorization so the county can withdraw payment for liens won from the registered account. No deposit is required. Returning Park County buyers keep their existing buyer number when registered under the same SSN, EIN or ITIN. For county-held certificates left over from prior sales, call 719-836-4202 or 719-836-4239, complete a W-9, and pay the certificate value plus a $4 assignment fee in cash or certified funds. Existing certificate holders can request Investor Portal credentials by calling 719-836-4239.

Sale format and venue
The Treasurer holds the annual tax lien sale on the internet, administered by SRI, Inc. at ZeusAuction.com, and posts the auction rules and procedures there before the sale. Bidding starts at the total amount published in the newspaper, and any amount above it is a premium bid that is not returned and earns no interest if the property is redeemed. The county calls it a "Buyer Beware Sale" and withholds liens it knows to be problems, so research each parcel before bidding. Certificate holders can change their mailing address at ZeusAuction.com while registration is open; after the sale, address changes go to the Treasurer's office. A lien is valid for 7 years from issue, and the holder may apply for a Treasurer's Deed after 3 years from the date of sale. 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. Endorsement amounts are not accurate until August 1 each year, and 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. 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.
Registration
What sells is a certificate of option for treasurer's deed, not the parcel outright.
When it runs
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.

Sale format and venue
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.

Park County tax sale list and auction calendar

For Park County tax sale 2026 searches, use the county-run sources below rather than a copied parcel list, and confirm the parcel, registration cutoff, deposit, and payment deadline against the county before you bid. If the parcels on this list are vacant land rather than houses, what buying land at a tax sale hands you is the place to start.

  1. Confirm the advertised parcel list

    Use 2026 Delinquent Tax Sale List and addendum, posted on ZeusAuction.com and updated daily until the morning of November 2, 2026 as a starting reference. Check which sale or list it covers; a Lands Available or office information page is separate from an auction parcel list. Ask the sale office for the advertised parcels for the auction you plan to attend.
  2. Register to bid

    What sells is a certificate of option for treasurer's deed, not the parcel outright. Full requirements are in the sale card above.
  3. Sale day

    Internet tax lien auction (bidding opens; closes in batches November 4) scheduled for November 2, 2026. Bidding runs on ZEUS; check posted sale dates, registration status, and bidding windows there.
  4. Confirm with the office

    If the list, platform, and notice disagree, use the County Treasurer as the source to confirm which parcels are actually offered.

Before you bid in Park County

  1. Confirm the parcel list before pricing

    Open 2026 Delinquent Tax Sale List and addendum, posted on ZeusAuction.com and updated daily until the morning of November 2, 2026. Confirm whether this reference contains the auction parcels or covers a different list. Get the advertised parcel list from the county before you price a bid, and recheck it before the sale.
  2. Confirm 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.

  3. Check the state rules that change the bid

    Read the Colorado due-diligence checklist before bidding. Redemption, liens that survive a tax deed, title cleanup, and payment deadlines can change what a parcel is worth. Which liens survive is state law, so read what survives a tax deed in Colorado before you price the title work.
  4. Set a walk-away number

    Work out what the parcel is actually worth with the rural land value estimator, then turn it into a ceiling with the tax deed max-bid calculator.

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.

County notes

  • Park County's official website moved from parkco.us to www.parkcountyco.gov, and old page IDs do not map cleanly across the redirect, so bookmarks to the older domain can land on the wrong department.
  • The Treasurer and Public Trustee is a combined office. Amy Flint is listed as Treasurer & Public Trustee. Office hours are Monday through Thursday, 7 am to 6 pm, with the office closed from 12 pm to 12:30 pm daily. The county's main fax is 719-836-3273.
  • Interest on delinquent real property tax accrues monthly starting in March, and the county applies an administrative fee on small delinquent balances.
  • Annual tax lien sale record PDFs are archived by year from 2018 through 2025. The files are large, so download them rather than viewing in a browser.
  • Park County is a fourth class county under the Colorado county treasurer fee schedule, which sets the statutory fee amounts the Treasurer may charge on certificates, endorsements, assignments, and Treasurer's Deed applications.

Colorado rules

Max interest rate
13% 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 past the three-year mark and into the Article 11.5 process. Once a deed application is pending, the owner must file an intent to redeem with the treasurer no later than seven calendar days before the scheduled public auction, then pay the amount on the redemption statement while it is in effect, and must redeem the entire property. The auction itself is set 30 to 60 calendar days after the treasurer mails the notice of public auction. A separate rule lets an owner who was under a legal disability when a tax deed was executed under Article 11 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 deposit up to one thousand dollars plus statutory fees when the application is accepted, applied against the treasurer's fees and costs, and all Article 11.5 fees and costs are chargeable as additional amounts owing under the certificate of purchase. A third-party winner may be charged up to three hundred dollars for processing. The statute sets no bidder deposit percentage, so payment terms come from the treasurer's written auction policies.
Surplus proceeds
Junior lienors whose liens were recorded before the application for treasurer's deed may file a claim for overbid money within eight business days after the auction. Between the ninth and fifteenth business day the overbid is paid to them in order of recording priority, each up to the unpaid lien plus fees and costs, and whatever remains goes to the property owner. The treasurer mails the owner a notice within thirty days after the claim period ends. Unclaimed overbid stays in escrow for two years without interest to the claimant. Amounts under twenty-five dollars left unclaimed for six months go to the county general fund, and larger amounts left unclaimed for two years go to the state treasurer as unclaimed property. An agreement to pay someone to recover an unclaimed overbid is enforceable only if the fee is capped at ten percent and the agreement is made at least two years after the transfer.
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.
