When it runs
South Dakota fixes the sale date by statute, so it does not move from county to county. On the third Monday of December each year, between nine a.m. and four p.m., the Treasurer offers a tax certificate at public sale at the courthouse for any real property carrying unpaid taxes from the preceding year or years, and may adjourn the sale from day to day until every certificate has been offered. The Department of Revenue gives county treasurers the same instruction, "Annual sale on 3rd Monday in December from 9:00 am to 4:00 pm". Campbell County publishes no sale calendar of its own, so call the Treasurer in Mound City at (605) 955-3388 during the autumn to confirm the hour and the room for the coming sale.
Registration and deposit

There is no online auction site and no bidder portal for this sale. Bidding happens in the room at the courthouse on sale day, so plan to attend in person or send a representative. Contact the Campbell County Treasurer at (605) 955-3388 well before the third Monday in December to confirm whether certificates will be offered to outside bidders at all this year, what identification the office wants, and which forms of payment it accepts. The winning bidder pays the full amount of delinquent taxes, interest and costs due on the parcel.

Sale format and venue
Settle one question before planning a trip: whether Campbell County offers certificates to outside buyers at all. South Dakota law prohibits a county from selling any tax certificate unless its board of county commissioners has adopted a resolution waiving that prohibition, and where no waiver is in place the county itself is the holder of every certificate the Treasurer issues. The Treasurer still publishes the notice, serves the owners and attends to the December sale either way, so a published sale notice is not by itself proof that certificates are available. Ask the Treasurer's office directly whether the commission has adopted the waiver. Where certificates are offered, the price is fixed and only the interest rate is competitive. A bidder must offer the full amount of taxes, interest and costs due and state in the bid the lowest annual rate of interest at which the bidder will carry the taxes. The lowest rate wins the certificate, and no bid above ten percent per year is valid. Because the amount paid is fixed at the delinquent total, there is no premium to bid and no way to overpay for a certificate. The statute sets that ten percent ceiling but names no floor, so competition can run the rate down to zero, and a bidder who wins at zero earns nothing on the certificate itself. Interest accrues annually on the certificate amount from the date of purchase at the rate bid, and separately on any later taxes the holder pays, running from the date each of those payments becomes delinquent. The county commission may adopt a fee of up to fifty dollars that is deducted from the proceeds paid to the certificate holder when a parcel redeems, and that fee cannot be charged to the property owner. Anything left unsold for want of bidders does not disappear. Once the sale closes and the Treasurer files the return with the county auditor, the Treasurer is required to sell any remaining certificate at private sale at the Treasurer's office to any person who pays the taxes, penalty and costs due, so an over-the-counter purchase is possible outside the December date. A certificate the Treasurer bid off in the county's name can also be taken over by paying the taxes, penalty, interest and costs of sale and transfer plus all unpaid and subsequent taxes, and that assignment carries the same rights as an original purchase at the sale.

Tax deed sale

In person
Run by
Campbell County Board of Commissioners, with deeds prepared by the Campbell County Treasurer
Frequency
annual
Typical timing
There is no annual deed auction calendar in South Dakota.
Registration
No standing bidder registration exists.
When it runs
There is no annual deed auction calendar in South Dakota. A certificate holder may begin the deed process no sooner than three years after the date of the tax certificate sale, and must complete it within six years of that date. Once a county takes a tax deed, it must declare the property surplus and sell it within one year of the deed being issued, giving notice by publishing at least twice with the first publication no less than thirty days before the sale date. Sale dates are therefore set parcel by parcel as deeds issue rather than on a fixed annual schedule, so watch the published notices and ask the Treasurer in Mound City what is coming.
Registration and deposit

No standing bidder registration exists. The method is chosen for each sale, and the published notice is what tells you which one applies. The default is sealed bids, filed with the county's fiscal officer and opened at a commission meeting at the time stated in the notice, or opened beforehand by a designated official and a witness if the notice says so. In place of sealed bids the county may sell the real property at public auction to the highest bidder, or list it with one or more licensed real estate brokers. The commission may reject every bid, but if it accepts one it must be the highest. A bidder who is not current on all property taxes due within the county can have a bid refused, so clear any county tax balance first. Call the Treasurer at (605) 955-3388 or the county Auditor at (605) 955-3366 to confirm where bids are filed and when they are opened.

Sale format and venue
South Dakota changed the economics of the deed step in February 2024, and it is the part that surprises investors arriving from other states. Any person other than a county who acquires real property by tax deed after being issued a tax certificate must offer that property at public auction within one year of the deed being issued. The former certificate holder is then compensated in the same manner as a redemption, meaning the certificate amount, interest at the rate bid, and any subsequent taxes with interest, while the remaining proceeds are distributed the way redemption money is distributed. A South Dakota certificate is an interest instrument, not a route to acquiring property below market value, and a strategy that depends on keeping the parcel or the upside does not work here. Before a deed can issue, the holder serves a notice of intention to take a tax deed. Personal service is required on the owner of record, on the person in possession, and on the person in whose name the property is taxed. Other interested parties, including mortgagees and lienholders appearing in the register of deeds, treasurer or clerk of courts records, may be served the same way, or by registered or certified mail with return receipt requested, or by publishing the notice once a week for at least two successive weeks in the county's legal newspapers. Service is complete when an affidavit stating how it was made is filed with the Treasurer, and the right of redemption does not expire until sixty days after that filing. The holder must also buy the assignment of every prior tax certificate the county holds on the parcel before the deed can issue. Immediately after the sixty days run out the Treasurer prepares the deed, signs it, has the county auditor attest it under seal and delivers it on return of the certificate, charging five dollars for each deed. The certificate does expire. If the deed proceeding is not completed within six years of the tax certificate sale date, the sale, the tax lien, the lien for any subsequent taxes the holder paid and all rights under them cease and are forever barred, and the Treasurer cancels the certificate on the county's records. An assignee inherits the original purchaser's clock rather than starting a fresh one. Sealed bid, public auction or listing with a licensed real estate broker, chosen sale by sale

Campbell County tax sale list and auction calendar

For Campbell 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 South Dakota newspaper legal notices, searchable by county for the current advertised parcels, then recheck it before the auction.

  2. Register to bid

    No standing bidder registration exists. Full requirements are in the sale card above.

  3. Sale day

    There is no annual deed auction calendar in South Dakota. The sale is live and in person; there is no online bidding platform. Confirm the venue and hour with the county office before you go.

  4. Confirm with the office

    If the list, platform, and notice disagree, use Campbell County Board of Commissioners, with deeds prepared by the Campbell County Treasurer as the source to confirm which parcels are actually offered.

Before you bid in Campbell County

  1. Start with the live sale list

    Pull the current advertised parcels from South Dakota newspaper legal notices, searchable by county. Lists can change before the sale, so recheck the county source before you price a parcel.

  2. Confirm registration and deposit

    No standing bidder registration exists. The method is chosen for each sale, and the published notice is what tells you which one applies. The default is sealed bids, filed with the county's fiscal officer and opened at a commission meeting at the time stated in the notice, or opened beforehand by a designated official and a witness if the notice says so. In place of sealed bids the county may sell the real property at public auction to the highest bidder, or list it with one or more licensed real estate brokers. The commission may reject every bid, but if it accepts one it must be the highest. A bidder who is not current on all property taxes due within the county can have a bid refused, so clear any county tax balance first. Call the Treasurer at (605) 955-3388 or the county Auditor at (605) 955-3366 to confirm where bids are filed and when they are opened.

  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

  • Campbell County does not maintain a county website, so nothing about the December tax certificate sale is posted online by the county. The Campbell County Treasurer in Mound City, reachable at (605) 955-3388, is the one place to confirm the sale, and the notice runs in print in the county's official newspaper the week before it is held.
  • South Dakota tax certificates are not sold on any online auction platform. The only three ways to acquire one are the December sale at the courthouse, a private purchase at the Treasurer's office of a certificate that went unsold for want of bidders, and an assignment of a certificate the county already holds.
  • Whether Campbell County sells certificates to private buyers at all depends on a resolution of its board of county commissioners. State law bars a county from selling any tax certificate unless the commission has waived that prohibition, and absent a waiver the county keeps every certificate the Treasurer issues. Confirm the county's position with the Treasurer before budgeting a trip or capital for the December date.
  • The Treasurer gives notice of the sale by publishing it once during the week before the sale in the county's official newspapers. If no newspaper is published in the county, the notice is instead posted at the courthouse door for two weeks beforehand. Ask the Treasurer which paper carries it, and begin watching in late November.
  • The published notice is built from taxes unpaid as of the close of business on the first Monday of December, and it carries the time and place of the sale, the list of certificates to be sold, the parties the taxes are assessed against or the current owner of record, and the amount of taxes due. That leaves roughly two weeks between the list being fixed and the sale itself, so parcel research has to move quickly.
  • If nobody bids the amount due on a parcel, the Treasurer may bid the certificate off in the name of the county, and the county then acquires all the legal and equitable rights a private purchaser would have had.
  • Any person may redeem at any time before a tax deed issues, by paying the Treasurer the sum stated in the certificate, interest on that sum at the rate the property sold at running from the date of purchase, any later taxes the holder paid, and interest on those at the same rate from the date of payment. The Treasurer holds the money for the certificate holder and notifies the holder immediately after a redemption, sending the notice to the address on the certificate or assignment record.
  • Confirm with the Treasurer that parcels will actually be offered before making the drive to Mound City. In a county this size the December session can be short, with only a handful of certificates or none available to outside bidders.
  • The Treasurer and the county Auditor both sit at the courthouse in Mound City. The Treasurer runs the December sale, issues the certificate, records assignments and later prepares the tax deed; the Auditor, reachable at (605) 955-3366, receives the return of the sale and attests the deed under seal.

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.
