How Big Horn 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.

Over-the-counter (leftover) purchases
unsold certificates
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
- 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.
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.
