Sweetwater County, Wyoming tax sales
How tax sales work in Sweetwater County, Wyoming
Wyoming law controls every tax sale in Sweetwater County — the county runs the sale, but what is sold, what it pays and how long the owner can redeem are all set by the state:
| What Wyoming sells | Tax lien certificates |
|---|---|
| Interest / penalty | 15% per year plus a one-time 3% penalty on the day of purchase (W.S. 39-13-108; county treasurer guidance) |
| Redemption period | 4 years from the date of the tax lien sale; the purchaser may apply for a tax deed after 4 years and no later than 6 years from the sale (W.S. 39-13-108, 39-13-109) |
| When sales happen | Annual county sales, typically July-September; exact date set by each county (e.g. Laramie County the Thursday after Cheyenne Frontier Days in late July, Platte County in July) |
| Governing law | Wyoming Statutes Title 39, Chapter 13 (W.S. 39-13-108, 39-13-109) |
| County (Census) | Sweetwater County — county, Wyoming · FIPS 56037 |
No rate or premium bidding: purchasers are chosen by random draw/lottery and pay taxes, interest and costs face value, so allocation — not price — is the competition. Purchaser must pre-register in person in counties such as Laramie; subsequent taxes may be paid by the purchaser and also earn 15%.
The process, step by step
1 · The list publishes. Wyoming sales run on this rhythm: Annual county sales, typically July-September; exact date set by each county (e.g. Laramie County the Thursday after Cheyenne Frontier Days in late July, Platte County in July) The county's sale list — the parcels actually being sold — is published ahead of the sale by the county office that runs it, and in many Wyoming counties also through the state's sale channels (Mostly in-person at the county treasurer / courthouse, allocated by random draw / lottery among registered purchasers; Some counties list sales online (e.g. via Bid4Assets listings / county online lottery) — confirm with the county).
2 · Register and fund — before sale day. Registration and bidder deposits are handled by the county or its sale platform and close before the sale, in most counties the day before. The amount and ID requirements are set in the county's own sale notice, not in state law — confirm them on the current published notice before you rely on them.
3 · Research every parcel. Compare the taxes owed against assessed value and recorded sales, check property type and occupancy signals, and price in the state's redemption rule above: it decides whether your money comes back with the statutory return, or your path runs to the property itself.
4 · Bid the number you wrote down. Set your max bid (deeds) or floor rate (liens) from the research, before the sale opens. The state's return is paid on the tax obligation — not on whatever extra a bidding war adds on top of it.
5 · After the sale. Owners redeem inside the window above; lists change as they do. Track the parcels you care about, because a watched property redeeming or withdrawing is information you want before — not after — you wire a deposit for the next sale.
