Pennington County tax certificate sales, South Dakota

Verified

The treasurer's property tax page says taxes are paid one year in arrears, the first half becomes delinquent after April 30 and the second half after October 31, the treasurer must publish delinquencies, and if taxes remain unpaid a tax certificate will be issued for the property. Its Tax Certificates and Tax Sales section gives the authorization rule, the third Monday of December date, and the statement that there was no annual tax sale in 2023. The auditor's tax deed page publishes the terms read before a tax deed sale: delinquent taxes, penalties, and interest are abated for the new owner, municipal special assessments stay with the property, the county issues and files a quit claim deed in the purchaser's name, the county makes no guarantee of marketable title, and a quiet title action is recommended.

Next sale: Monday, December 21, 2026 is the statutory third Monday date for a certificate sale, from 9 a.m. to 4 p.m. at the courthouse under state law. Pennington County publishes only the third Monday rule and no date confirmation, authorization, or list for 2026, and its auditor page says there is not a tax deed auction scheduled.. A 2026 certificate sale would appear through a Board of Commissioners authorization and the treasurer's property tax page, with the sale list published in the county's official newspapers during the week before the sale under state law. Tax deed land auctions appear on the auditor's Tax Deeds page, with the auditor at 605-394-2153.

Ask the treasurer at 605-394-2163 whether the board has authorized any assignment or a December 2026 sale before planning to bid, because no sale ran in 2023 and none is published for 2026. For land, watch the auditor's Tax Deeds page for a scheduled auction.

Research Pennington 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 Pennington County, searchable by address, owner, or county, including parcels that never reach a sale list.

How South Dakota tax certificate sales work

• The sale sits on the calendar by statute. On the third Monday of December each year, between 9 a.m. and 4 p.m., the treasurer offers at public sale at the courthouse a tax certificate for every parcel with unpaid taxes from the preceding year or years, adjourning from day to day until all certificates are offered. The list closes at the end of business on the first Monday of December, and notice is published once during the week before the sale in the county official newspapers (SDCL 10-23-2, 10-23-3 and 10-23-7).
• Where the public may bid, bids are interest rates. A bidder pays the full taxes, interest and costs and names the interest rate the bidder will accept; the lowest rate is the best bid, and no rate above 10 percent per year is a valid bid. The treasurer collects $10 for each certificate (SDCL 10-23-8 and 10-23-19).
• Since 2006 the county is the default holder. No county may sell any tax certificate unless its commissioners have adopted a resolution waiving SDCL 10-23-28.1, and the county is the holder of any certificate it issues. A certificate nobody buys is bid off to the county, a county held certificate bears interest at the Category G rate, and the property is not readvertised while the county keeps its interest (SDCL 10-23-24, 10-23-25, 10-23-26 and 10-23-28.1).
• The assignment is the standing public route. Any person may pay the treasurer the taxes, penalty, interest and costs on a county held certificate, together with every unpaid and subsequent tax on the parcel, and take an assignment of the county certificate with all the rights the county had, as if the person were the original purchaser (SDCL 10-23-27 and 10-23-28). A waiver county also sells unsold certificates at private sale after the December sale closes (SDCL 10-23-12).
• Redemption runs until the deed issues. From a private holder the owner pays the certificate sum plus interest at the rate the property was sold, plus later taxes paid at the same rate; the county may deduct a fee of up to $50 from the holder's proceeds on redemption. From the county the owner pays all delinquent taxes with penalty and interest plus the costs of advertising and selling (SDCL 10-24-1, 10-24-5 and 10-23-8).
• The deed proceeding has a hard clock. It may be started after three years from the sale and must be completed within six years, or the certificate and the lien are cancelled and forever barred; the same clock binds the county. Before any deed, the holder must buy up every prior tax certificate the county holds on the parcel. Notice of intention is served on the owner of record, the person in possession, the person in whose name the property is taxed, and mortgagees, lienholders and creditors of record, and redemption finally expires 60 days after the affidavit of completed service is filed (SDCL 10-25-1, 10-25-3, 10-25-8, 10-25-10 and 10-25-16).
• Since 2024, a deed ends in an auction. Whoever takes a tax deed, the county or a private holder, must offer the property at public auction within one year of the deed; the proceeds pay the deed and sale expenses first, are prorated across the tax levies until all tax and interest are paid, and any surplus left after taxes, penalty, interest, county liens and other costs is returned to the prior owner of record, or sent to the Unclaimed Property Division if the owner cannot be found within 180 days (SDCL 10-25-39, 10-25-39.1 and 10-25-39.2).

How buying works in Pennington County

The county publishes no bidder registration, bidder number, or assignment application rules. Its only published rule is that an assignment or an annual sale requires authorization by the Board of Commissioners.

• Where buying happens It depends on the county channel, and the channel is the first fact on each county page here: a county whose commissioners waived SDCL 10-23-28.1 sells to the public at the December sale; elsewhere the purchase is an assignment of a county held certificate at the treasurer's office, or a bid at the county auction of tax deed land.
• At a public sale, the bid is a rate Bidders pay the full amount due and compete on the interest rate, lowest rate winning, with 10 percent per year the legal ceiling. There is no premium bidding in South Dakota (SDCL 10-23-8).
• On an assignment, the price is everything owed The county assigns its certificate only after every tax on the parcel is paid in full, including the amount the certificate was bid off for and all later taxes (SDCL 10-23-27).

Terms: what a bid actually costs

Certificates the county keeps unless the board authorizes a sale

A certificate that draws no buyer is bid off to the county, and under SDCL 10-23-28.1 the county holds every certificate it issues unless its commissioners adopted a waiver resolution. Pennington County's own page frames any public route as an assignment or a sale the board authorizes. Land the county later takes by tax deed goes to the auditor's tax deed auction, and since February 12, 2024 that auction must happen within one year of the deed, with any surplus over taxes and costs returned to the prior owner under SDCL 10-25-39 and 10-25-39.1.

Before you bid

• Ask the waiver question first Whether the public can buy certificates in a county at all turns on a commission resolution that many treasurers never mention on their websites. Ask the treasurer directly which channel the county runs before planning around the December date.
• Mind the six year bar A certificate is a wasting asset: if the deed proceeding is not completed within six years of the sale, the treasurer cancels the certificate and the lien is extinguished. An assignment from the county on a certificate more than four years old restarts a one year window to begin (SDCL 10-25-16 and 10-25-17).
• The deed is not the finish line Since February 2024 a private deed holder must auction the property within a year and keeps only the redemption measure of taxes, interest and costs; the surplus belongs to the former owner. Price a South Dakota certificate as an interest play with an auction at the end, not as a quiet route to keeping land (SDCL 10-25-39.2).
