How Wyoming Tax Sales Work

Wyoming sells tax lien certificates, and nobody bids on them. The price of each certificate is the tax bill plus interest, penalties and costs, and the return is written into the statute: a one-time 3% penalty plus 15% a year. When several buyers want the same parcel, the county draws a number. You cannot outbid anyone, and you cannot bid the rate down either.

The other difference comes at the end. Wyoming holds no county tax deed auction. An unredeemed holder applies to the treasurer for a deed, inside a fixed window, after serving notice. Miss the window and a lawsuit is the only road left.

Start with the Wyoming tax sales hub for treasurer offices and sale dates, then how to buy tax liens in Wyoming for the buyer's sequence. New to the distinction? Read tax liens compared to tax deeds. The rules sit in W.S. Title 39, Chapter 13, mainly 39-13-108 and 39-13-109.

Step 1: The tax goes delinquent in May

Wyoming bills property tax in two halves. The first half is payable from November 10 and the second from May 10 of the next year, and nothing accrues if the whole bill is paid by December 31. Any unpaid half becomes delinquent and bears 18 percent a year until paid. That rate is the county's charge to a late taxpayer. A certificate buyer earns the return in Step 4.

Each year the treasurer declares taxes still unpaid on May 11 delinquent and certifies the delinquent roll by May 21. That roll feeds the summer sale. The tax is a perpetual lien on the parcel against everyone except the United States and the State of Wyoming, and a homestead may be sold only for the taxes due on it alone.

Step 2: Find the county's date, because the state sets none

The statute fixes the notice, not the day. Each treasurer advertises the sale once a week for three weeks in a legal newspaper in the county, with the first notice four weeks or more before the sale and before the first week of September. A county with no legal newspaper posts the notice at the courthouse door and in three public places 30 days ahead. The notice carries the delinquent list.

Sales run at the courthouse or a county building, never on a Sunday, and may continue day to day. Most land between late July and early September. Laramie County sells the Thursday after Cheyenne Frontier Days, Sweetwater County set its 2026 sale for August 6, and Natrona County held its 2026 drawing on September 3. No state agency publishes a calendar, so browse every Wyoming county and read each treasurer's page. Finding tax sale property lists covers the newspaper route.

Step 3: Register, then take your chances in the draw

W.S. 39-13-108(e)(iii)(B) makes any person who offers to pay the amount due on a parcel its purchaser, and that buyer pays at once. Every offer is the same figure, so the statute gives the treasurer nothing to rank. The counties fill that gap with a lottery. Laramie, Campbell and Albany counties assign each registered buyer one number, draw a number for each parcel as it is announced, and let the holder of the drawn number buy or pass. Natrona County registers buyers online and runs the drawing in the treasurer's office.

What that means for a buyer:

• You cannot pay more to win. Volume depends on how many buyers registered that year.
• Passing is your only filter. Research the list before the sale, because you decide in seconds whether a drawn parcel is worth holding.
• Formats vary. The statute does not require a lottery, and a county can allocate another way. Confirm the method with the treasurer before you register.

The statutory deed form in 39-13-108(e)(vi)(A) still recites "the least quantity bid for," wording left from an older auction. The operative purchaser rule contains no quantity bid.

Run due diligence before a tax sale on every parcel you might keep. The special assessments line in the notice matters here, because both the certificate and any later deed stay subject to them.

Step 4: What a certificate earns

W.S. 39-13-109(e)(iv)(A) prices redemption as the amount the parcel sold for, plus the 3% penalty, plus 15% a year from the date of sale. The amount paid includes the advertising charge of up to 20 dollars and the certificate fee of up to 20 dollars, so both earn interest.

The penalty is added once, on top of the interest, so the two stack. A certificate redeemed one month after the sale returns the whole penalty plus one month of interest, which makes quick redemptions the best annualized outcome a Wyoming holder sees.

Three more pieces belong in the model:

• Subsequent taxes. Taxes the holder pays on the parcel after the sale earn the same annual rate.
• Notice costs. Once the holder has served notice of intent to apply for a deed, a redeeming owner also reimburses actual expenses up to 250 dollars on a sworn statement.
• Compounding. The statute states an annual rate and no compounding rule. Albany County's handout applies it to the days held since the sale.

Model a certificate with the tax lien yield calculator, treating the penalty as a one-time add.

Step 5: The owner redeems through the treasurer

The statute sets the owner's window this way:

At least 4 years from the sale; the right ends when a valid tax deed application is filed and accepted, which can happen from 4 to 6 years after the sale

The legal owner or the owner's assigns may redeem. A mortgagee, or a buyer at a mortgage foreclosure sale, may redeem the certificate for just the portion of the parcel it holds an interest in, and the rest of the certificate stays in force. The owner pays the treasurer, who holds the money for you and notifies you.

Because the window stays open until you apply, your holding period is partly your own choice. Compare that structure with fixed-clock states in redemption periods explained, and date your own milestones with the redemption deadline calculator.

Step 6: Serve notice, then apply inside the window

The treasurer accepts a tax deed application no sooner than four years after the original sale and no later than 6 years after it. You return the certificate, pay the 25 dollar deed fee and prove notice.

Notice comes first, three months or more before you apply. Serve it in writing on everyone in actual possession of the parcel and on the person it was taxed to, if they can be found in the county. If nobody occupies the property and the taxpayer cannot be found, publish instead, once a week for three weeks in a county newspaper, with the first run no more than five months and the last no less than three months before the application. Either way, also send it by certified or registered mail to the record owner and every mortgagee with a known address.

Miss the window and the deed route closes, but the certificate lien does not. W.S. 39-13-110(c) lets you foreclose it in district court like a mortgage, filed four years or more after the sale and within a decade of it. The owner may redeem until the court confirms the sheriff's sale. Calendar the application date the day you buy.

Step 7: What the deed gives you, and what it keeps from the owner

A tax deed is prima facie evidence of title and entitles you to possession, and anyone seeking to set it aside carries the burden of proof. W.S. 39-13-110 bars an action to recover land sold for taxes brought more than 6 years after the tax sale. The deed stays subject to special assessments for local improvements.

Nothing in Chapter 13 pays the former owner any value above the certificate on the treasurer's deed route. The judicial route is different: sale proceeds pay the costs of the action, then the lienholder, and the balance goes to holders of prior interests, with no deficiency judgment allowed. Read what survives a tax deed and budget a quiet title action before you count on a resale.

County-held certificates, and notices that are not sales

A parcel nobody pays for at the sale is bid in for the county by the treasurer during that same sale. The board of county commissioners may later sell and assign any county-held certificate at a public or private sale at any time, and an assignee takes every right the original purchaser had. The statute leaves price and procedure to the commissioners, so ask each treasurer what it holds. Over the counter tax liens explains how assignments work elsewhere.

Redemption from a county-held certificate carries the annual interest but not the penalty. After four years the treasurer deeds an unredeemed county parcel to the county, following 60 days of notice from the county clerk, and the commissioners may then sell the land itself privately on no statutory schedule.

Two newspaper notices look like sales and are not: a holder's notice of intent to apply for a tax deed, and the county clerk's 60-day notice before a deed issues to the county. Neither offers a certificate.
