How Tax Delinquent Property Sales Work in Idaho
Idaho is a pure tax-deed state with no tax-lien certificates for investors to buy. After roughly three years of delinquency, the county takes a tax deed to the property — deeding it to itself — and then resells it free of the former owner's redemption right at an auction conducted by the board of county commissioners. The winning bidder receives a county deed conveying the county's tax-deed title. Because the county must auction tax-deeded property no later than 14 months from the issuance of the tax deed, and counties schedule these sales individually (often annually or as inventory accumulates), there is no fixed statewide date. Inventory is thin and irregular: investors are buying whatever properties the county has already deeded to itself, not a predictable annual pool of liens or certificates.
Bidding & Auctions
Idaho tax-deed auctions are premium-bid, highest-bidder sales conducted by the board of county commissioners; some counties use sealed bids instead. The minimum bid is typically set to cover back taxes, costs, and sometimes market value, and the property goes to the highest bidder. Sales are primarily in-person county commissioner auctions, with some counties posting via the county treasurer's website; there is no dominant statewide online platform. Since the county is reselling property it already owns, buyers should review each county's auction terms and minimum-bid rules, which vary, and watch individual county treasurer announcements rather than a central calendar.
Redemption & Penalties
There is no post-sale redemption right for the auction buyer. The owner's redemption right runs only up to the point the county takes the tax deed, after roughly three years of delinquency; before that, the owner may redeem by paying all delinquent taxes, late charges, accrued interest, and costs. Idaho Code 63-1007 does allow redemption for up to 14 months after the tax deed issues to the county, but that right is extinguished the moment the commissioners enter a contract of sale or transfer the property by county deed. So once you buy at the county resale auction, the property is yours with no redemption exposure — one of Idaho's key attractions for buyers seeking clean ownership.
See Idaho Code, Title 63, Chapter 10 (redemption at 63-1007). Specific procedures vary by county — always verify with the local tax assessor/collector before bidding.

A list can be current for the county's release cycle without changing every day. Verify property and tax details with the county before acting.
What data fields are included?▾

Can I buy a tax-lien certificate in Idaho?▾
No. Idaho has no tax-lien certificate for investors. The county first deeds the delinquent property to itself after about three years, then resells it at a county commissioners' auction.
Is there a redemption period after I buy at the auction?▾
No. The owner's redemption right ends when the county takes its tax deed and is fully extinguished once the commissioners contract to sell, so a purchaser at the resale auction takes the property with no redemption exposure.
When are Idaho tax-deed auctions held?▾
There's no fixed statewide date. Counties must auction tax-deeded property within 14 months of the tax deed issuing to the county, and each county schedules its own sale — often annually or as inventory accumulates.
How does bidding work in Idaho?▾
It's a highest-bidder auction run by the board of county commissioners, though some counties use sealed bids. The minimum bid typically covers back taxes, costs, and sometimes market value.
