Fremont County tax lien sales, Wyoming

Verified

What the county does publish is the ordinary tax calendar, and it runs later than most: Fremont County tax bills are mailed on or before October 10, and a taxpayer who has not received a bill by the end of October is told to call the treasurer at (307) 332-1105. Treasurer Jim Anderson's office also maintains the table of approved mill levies for every tax district in the county. At a May 12, 2026 budget presentation, county officials described the delinquent tax process, including tax sales and interest assessments, and noted that about 99.9 percent of taxes are collected within ten years, which is the closest the county comes to publishing a tax sale result.

Next sale: The county does not publish a dated next or most recent tax sale on its treasurer pages.. No tax sale date, sale list or sale notice appears on the treasurer's site, so the next date has to be confirmed with the treasurer's office.

Start with a call to the treasurer at (307) 332-1104 to ask for the sale day, the venue, the registration steps and the payment the office accepts, since none of that is posted. Owners should note the county's own warning that taxes are due whether or not a bill arrives.

Research Fremont County parcels before you bid

A sale list gives you the parcels, the date, and the opening terms. It does not give you the owner, the value, or the rest of the picture: liens, foreclosure status, and parcel history. PropertyRadar is the data platform for that layer. It carries owner records, assessed and market values, foreclosure and tax data, and property history for parcels across Fremont County, searchable by address, owner, or county, including parcels that never reach a sale list.

How Wyoming tax lien sales work

Taxes fall delinquent in halves. Half the tax is payable November 10 and the rest the following May 10; a balance left unpaid bears interest at 18 percent per annum until paid or collected, and taxes on real property are a perpetual lien against everyone but the United States and the state (W.S. 39-13-108(b) and (d)(i)).
The treasurer advertises the sale. Notice of the sale runs by publication once a week for three weeks in a legal newspaper in the county, the first publication at least four weeks before the day of sale and before the first week in September; where the county has no legal newspaper, the notice is posted at the courthouse door and in three public places at least 30 days ahead (W.S. 39-13-108(e)(ii)(A)).
The sale is held at the courthouse. Sales run at the county courthouse or county building between 9 a.m. and 5 p.m. and continue from day to day, Sundays excepted, until all the land is sold. There is no bidding on price: any person who offers to pay the whole amount of taxes, interest, penalties and costs due on a parcel is the purchaser, and the purchaser pays on the spot or is disqualified and the parcel is offered again (W.S. 39-13-108(e)(iii)(A) and (B)).
A certificate of purchase issues. On payment of the certificate fee the treasurer makes out and delivers a certificate of purchase describing the property and the taxes and costs paid; the certificate may be assigned by endorsement, and the holder takes subject to any special assessments for local or public improvements (W.S. 39-13-108(e)(iii)(C) and (E)).
Redemption runs four years. The owner redeems at the treasurer by paying the amount for which the property sold, a penalty of 3 percent, interest at 15 percent per annum, and a redemption fee; a purchaser who pays later taxes on the parcel earns the same 15 percent on those payments (W.S. 39-13-110).
The deed window opens at four years and closes at six. A holder applies to the treasurer for a tax deed not less than four nor more than six years from the date of the original sale, proving the statutory notice: personal service at least three months before the application on anyone in actual possession and on the person in whose name the property was taxed, or publication once a week for three weeks on the statutory timing, plus certified or registered mail to the record owner and any mortgagees (W.S. 39-13-108(e)(v)).
The county path runs beside the private one. Property nobody buys is bid in for the county; the commissioners may sell and assign a county certificate at public or private sale at any time, and four years after the sale the treasurer deeds unredeemed county parcels to the county itself, on at least 60 days notice from the county clerk, after which the commissioners may sell the land at private sale (W.S. 39-13-108(e)(iii)(D) and (e)(iv)).

How buying works in Fremont County

The county does not publish bidder registration rules, an attendance or age requirement, or a lottery or rotation system for choosing among buyers.

Where buying happens At the county treasurer sale each summer. The day, the room, and the registration rules are the county's own, and each county page on this site names them from that treasurer's published pages.
No auction in price The amount due is the price, set by the statute. Where two buyers want the same parcel, the treasurer's published rules decide who pays: several Wyoming counties draw lots or work down a rotation of registered buyers. The registration statement at the top of each county page carries the rule that county publishes, or says plainly that the county does not publish one.
Payment is immediate A purchaser who does not pay the treasurer all amounts due at once is disqualified, and the parcel is offered again on the spot (W.S. 39-13-108(e)(iii)(B)). Accepted payment forms differ by county and are stated on each county page.

Terms: what a bid actually costs

Deposit, Fremont County	The county does not publish a deposit requirement for tax sale buyers.
Payment, Fremont County	The county does not publish the forms of payment it accepts from tax sale buyers, or when sale purchases must be paid, on its treasurer pages.
Redemption period	Four years from the date of sale. The owner redeems at the county treasurer at any time before a tax deed issues (W.S. 39-13-110).
What redemption pays	The amount for which the property sold, a penalty of 3 percent on that amount, interest at 15 percent per annum, and a redemption fee. Later taxes a purchaser pays on the parcel earn the same 15 percent (W.S. 39-13-110).
Interest before the sale	Delinquent taxes themselves bear interest at 18 percent per annum from the day after they were payable until paid or collected (W.S. 39-13-108(b)(ii)). That 18 percent is the county charge on the owner; the 15 percent above is what a certificate pays its holder.
The price at the sale	Fixed by law at the whole amount of taxes, interest, penalties and costs due on the parcel. There is no premium and no bid down in Wyoming; the contest, where there is one, is over who gets to pay, under the selection rules each county publishes (W.S. 39-13-108(e)(iii)(B)).
Deed window	A tax deed may be applied for not less than four nor more than six years from the date of the original sale. Miss the window and the certificate no longer ripens into a deed on that sale (W.S. 39-13-108(e)(v)(A)).
Fees	The treasurer collects not more than $20 for issuing a certificate of purchase, $25 for issuing a treasurer deed to a private purchaser, and not more than $20 for issuing a certificate of redemption (W.S. 39-13-108(e)(ix)). Counties add their published advertising charge to the amount due.
County certificates and county land	The commissioners may sell and assign any certificate bid in for the county at public or private sale at any time, and may reject bids at a public sale. After the treasurer deeds unredeemed parcels to the county, the commissioners may dispose of the property at private sale (W.S. 39-13-108(e)(iii)(D) and (e)(iv)(B)).
Tax bill mailing	On or before October 10, later than the August mailing many counties use
Mill levies	The treasurer maintains a table of approved mill levies for all tax districts in the county
Full payment shortcut	Paying the whole tax by December 31 waives the penalty on the first half

Parcels that receive no bids

The county does not publish its own practice for unsold parcels, for later sales or assignments of county held certificates, or for sales of tax deeded county land. Under Wyoming law, property that nobody buys is bid in for the county, the commissioners may later sell and assign those county certificates at public or private sale, the treasurer deeds unredeemed county held certificates to the county four years after the sale, and the commissioners may sell that land at private sale.

Before you bid

Recheck the list on sale morning Owners redeem and parcels are pulled right up to the sale. The list in the newspaper notice is the starting list, not the final one; work from the treasurer posted list and expect it to shrink.
Price the wait, not just the rate The certificate pays 15 percent plus the 3 percent penalty only if the owner redeems. If nobody redeems, the money is out for at least four years before a deed can be applied for, and the application window closes at six years from the sale.
Know what the deed gives you A treasurer deed is prima facie evidence of title and entitles the grantee to possession, but it is subject to special assessments, and an action to recover property sold for taxes may be brought within six years after the sale. Budget for your own title work on any parcel that matters (W.S. 39-13-108(e)(vii)).
