Sale list
Public Notices, Douglas County
When it runs
Third Monday of December each year, between 9:00 a.m. and 4:00 p.m., at the Douglas County Courthouse in Armour. The treasurer may adjourn the sale from day to day until every certificate has been offered.
Registration and deposit

No online registration and no published deposit. Bidders attend in person at the courthouse and bid parcel by parcel in the order the property appears on the tax list. Call the Treasurer at 605-724-2318 before the sale to confirm payment terms and whether the county commission has authorized certificates to be sold to private bidders.

Sale format and venue
Bidding runs down, not up. The price is fixed at the full delinquent tax, interest and costs, so there is no premium to pay; bidders compete by naming the lowest annual interest rate they will accept, and the lowest rate wins. A valid bid may not exceed 10 percent a year and no minimum rate is set, so a certificate can be bid all the way down to zero. The sale list runs once during the week before the sale in the county's official newspapers, the Armour Chronicle and the Corsica Globe, and the treasurer mails notice to owners at least 14 days ahead. Certificates left unsold for want of bidders can be bought afterward at the treasurer's office for the taxes, penalty and costs due. Settle one point before you travel: South Dakota bars a county from selling certificates to private buyers unless its board of commissioners adopts a resolution waiving that ban, and Douglas County has recently been keeping delinquent property in county hands, taking title by tax deed and reselling it at a sheriff's auction. Redemption runs until a tax deed issues, with interest at the rate bid from the date of purchase, plus the same rate on any later taxes the holder pays. A holder may begin deed proceedings three years after the sale, must serve notice of intention to take a tax deed on the owner, the occupant, the person taxed, mortgagees and other lienholders of record, and redemption then ends 60 days after the affidavit of completed service is filed with the treasurer. The certificate is not open ended: if the deed proceeding is not completed within six years of the sale, the certificate and its lien are cancelled and barred.

Commission Minutes, Douglas County
When it runs
Set by county commission resolution as parcels come out of the tax deed process, not on a fixed annual calendar. The most recent auction was held December 2, 2025 at 8:30 a.m.
Registration and deposit

In person bidding, open to the public, with no online registration. Watch the commission agendas and minutes for the parcel list and the auction date, or call the Treasurer at 605-724-2318.

Sale format and venue
This is the route by which tax delinquent property in Douglas County actually reaches the open market. The board of commissioners declares parcels taken by tax deed to be surplus, sets an auction date and the sheriff sells to the highest bidder. Two parcels sold at the December 2, 2025 auction, one near Dimock at $64,000 and one in Armour at $31,000. The commission approves each winning bid at its meeting, so a sale is not final on auction day.

Douglas County tax sale list and auction calendar

For Douglas County tax sale 2026 searches, use the county-run sources below rather than a copied parcel list, and confirm the parcel, registration cutoff, deposit, and payment deadline against the county before you bid. If the parcels on this list are vacant land rather than houses, what buying land at a tax sale hands you is the place to start.

  1. Get the advertised list

    Use Commission Minutes, Douglas County for the current advertised parcels, then recheck it before the auction.

  2. Register to bid

    In person bidding, open to the public, with no online registration. Full requirements are in the sale card above.

  3. Sale day

    on the third Monday in December, 2026 The auction platform is still being verified. Confirm the next sale date and registration window with the county before you bid.

  4. Confirm with the office

    If the list, platform, and notice disagree, use Douglas County Sheriff as the source to confirm which parcels are actually offered.

Before you bid in Douglas County

  1. Start with the live sale list

    Pull the current advertised parcels from Commission Minutes, Douglas County. Lists can change before the sale, so recheck the county source before you price a parcel.

  2. Confirm registration and deposit

    In person bidding, open to the public, with no online registration. Watch the commission agendas and minutes for the parcel list and the auction date, or call the Treasurer at 605-724-2318.

  3. Check the state rules that change the bid

    Read the South Dakota due-diligence checklist before bidding. Redemption, liens that survive a tax deed, title cleanup, and payment deadlines can change what a parcel is worth. Which liens survive is state law, so read what survives a tax deed in South Dakota before you price the title work.

  4. Set a walk-away number

    Work out what the parcel is actually worth with the rural land value estimator, then turn it into a ceiling with the tax deed max-bid calculator.

Over-the-counter (leftover) purchases

Three routes exist and each runs through a county office. A certificate that stayed unsold for want of bidders must be sold at private sale at the treasurer's office to any person who pays the taxes, penalty and costs due. A person may also buy the county's interest in a certificate the treasurer bid off, by paying the taxes, penalty, interest and costs of sale and transfer plus every unpaid and subsequent tax, after which the treasurer assigns the certificate and the buyer holds the rights of an original purchaser. Both routes are closed in a county whose commissioners have not waived SDCL 10-23-28.1. Separately, tax deed property the county offered that drew no bid may be sold at private sale within twelve months for not less than ninety percent of the appraised value, without further publication or appraisal. Ask the county treasurer about certificates and the county auditor about unsold deeded parcels.

County notes

  • The Douglas County Treasurer runs the December tax certificate sale, issues the certificate and later issues the tax deed. The office is at 706 Braddock St. in Armour, mail goes to PO Box 68, Armour, SD 57313, and the phone is 605-724-2318.
  • Nothing about this sale happens online. Legal notices run in the county's official newspapers, the Armour Chronicle and the Corsica Globe, and are posted on the bulletin board in the second floor lobby of the courthouse.
  • Property the county takes by tax deed is declared surplus by the board of commissioners and resold at an in person sheriff's auction, which is where a buyer is most likely to find Douglas County land actually on offer.
  • The county commission meets the first and third Tuesday of each month at 9:00 a.m. in the commission chambers on the second floor of the courthouse, and surplus parcel resolutions appear in those minutes.

South Dakota rules

Max interest rate
10% per year, bid down at auction
Minimum return
No statutory minimum; interest accrues at your bid rate
Redemption
There is no fixed redemption deadline that starts at the sale. SDCL 10-24-1 lets any person redeem at any time before a tax deed is issued. What sets the outer limit is the deed process: SDCL 10-25-1 bars the certificate holder from starting that process until three years after the certificate sale, and SDCL 10-25-8 keeps the right to redeem alive until sixty days after the affidavit of completed service of the notice of intention is filed with the treasurer. Missing that sixty-day window passes the owner's, mortgagee's and lienholder's interests to the certificate holder. After the deed is recorded, the former owner has one hundred eighty days to bring an action to recover possession or to avoid the deed, which is a limitation period rather than a further right to redeem.
Deed deposit
Chapter 6-13 sets no deposit for a cash sale. A buyer taking an installment contract must deposit the cash portion with the fiscal officer as soon as the bid is accepted, and the board can still decline to approve the sale, in which case the deposit is returned. A separate rule bars a bidder from the sale entirely: under SDCL 10-25-45 a county may refuse a bid from any person who is not current on all property taxes due within that county. Payment methods and any county-set deposit are county practice rather than statute, so confirm them with the county before bidding.
Surplus proceeds
The county first deducts the expenses of taking the tax deed and of the sale. What remains is prorated to the taxing districts on the levies for the most recent year included in the proceeds until all tax and interest is paid. Any surplus left after taxes, penalty, interest, county liens and other costs must be returned to the prior owner of record, and if that owner cannot be found within one hundred eighty days the surplus is transferred to the Unclaimed Property Division under SDCL chapter 43-41B. The same distribution binds a private buyer. SDCL 10-25-39.2, effective February 12, 2024, requires any person other than a county who acquires property by tax deed after being issued a tax certificate to offer that property at public auction under chapter 6-13 within one year of the deed, and entitles that seller only to compensation in the same manner as a redemption under SDCL 10-24-1. A South Dakota certificate is therefore a route to being paid what the certificate is worth, not a route to keeping the land.
Governing statute
SDCL Title 10, Chapter 10-23

A tax deed does not convey marketable title. Most buyers file a quiet title action before they can resell or insure the property. See the due diligence guide.
