How Park County sells delinquent taxes

From lien to deed

Wyoming holds no county tax deed auction. A certificate holder whose certificate is not redeemed may apply to the county treasurer for a tax deed not less than four nor more than six years after the original sale, returning the certificate, paying the 25 dollar deed fee and proving notice. At least three months before applying, the holder must serve written notice on every person in actual possession or occupancy and on the person the property was taxed to, if they can be found in the county; if nobody occupies the property and the taxpayer cannot be found, the holder instead publishes the notice once a week for three weeks in a county newspaper, the first publication not more than five months and the last not less than three months before applying. Either way the holder must also send notice by certified or registered mail to the record owner and any mortgagees whose addresses are known. The notice states when the holder bought, the name the parcel was taxed in, its description, the tax year, when redemption expires, when the deed application will be made, and any special assessments. Where the county itself holds an unredeemed certificate, the treasurer issues and records a tax deed to the county after four years, following at least 60 days' notice from the county clerk to the person assessed and any mortgagees. The published notices of intent to apply are not sales.

Sale format and venue
The Treasurer sells certificates of purchase on delinquent real property in person at Heart Mountain Hall, Park County Fairgrounds, 655 E. 5th Street, Powell. The published sale list names each owner, parcel and the total amount (taxes, penalty, interest and costs) for which the property will be sold, and property is sold subject to all special assessments for local or public improvements. Delinquent taxes carry 18% per annum interest. The Treasurer's office provides a Certificate of Purchase reassignment form for holders transferring a certificate.

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.

  1. Get the advertised list

    Use 2025 Property Tax Sale notice (parcels and amounts due) for the current advertised parcels, then recheck it before the auction.
  2. Register to bid

    Ask the county office how and when to register; many counties close registration days or weeks before the sale.
  3. Sale day

    Held each August. The sale is live and in person; there is no online bidding platform. Confirm the venue and hour with the county office before you go.
  4. Confirm with the office

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

Before you bid in Park County

  1. Start with the live sale list

    Pull the current advertised parcels from 2025 Property Tax Sale notice (parcels and amounts due). Lists can change before the sale, so recheck the county source before you price a parcel.
  2. Confirm registration and deposit

    Register with the Park County Treasurer's Office before the sale; the Treasurer requires a completed IRS Form W-9 for tax sale registration. Call (307) 527-8630 for bidder sign-up details.

  3. Check the state rules that change the bid

    Read the Wyoming due-diligence checklist before bidding. Redemption, liens that survive a tax deed, title cleanup, and payment deadlines can change what a parcel is worth.
  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

Parcels that no one buys at the sale are bid in for the county. The board of county commissioners may sell and assign those county-held certificates at public or private sale at any time, and the assignee takes all the rights of an original purchaser. Whether a county offers them over the counter, and at what price, is set by that county; ask the county treasurer.

Wyoming rules

Max interest rate
15% per year, fixed by statute (nothing is bid)
Minimum return
3% one-time penalty at redemption, added on top of the interest
Redemption
The legal owner may redeem at any time after the sale until a valid tax deed application has been filed with and accepted by the county treasurer. Because the treasurer cannot accept an application until four years after the sale, every owner has at least four years; after that the window stays open until the holder applies, and the holder must apply by the sixth year or lose the deed route. Redemption money is paid to the county treasurer, who holds it for the certificate holder, issues a certificate of redemption and notifies the holder. Where the county holds the certificate, the treasurer deeds the parcel to the county after four years. Where the holder instead forecloses in district court, anyone with an interest in the property may redeem until the court confirms the sheriff's sale.
Surplus proceeds
The treasurer's deed route conveys the parcel to the certificate holder, and nothing in Chapter 13 provides for paying the former owner any value above the certificate. On the judicial route, proceeds go first to the costs of the action and sale, including an attorney's fee allowed by the court, then to the lienholder, and the balance to persons holding prior interests in the property as their interests appear. That balance must be claimed within two years of the court's confirmation of the sale, or within one year after a legal disability ends, and unclaimed money is credited to the county sinking fund. No deficiency judgment may be entered.
Governing statute
W.S. Title 39, Chapter 13

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.
