How Brookings County sells delinquent taxes

Tax certificate sale (lien)

In person
Run by
Brookings County Finance Office (the county's combined Treasurer and Auditor)
Frequency
annual
Next expected
on the third Monday in December, 2026 (window; exact date posts closer to the sale)
When it runs
South Dakota sets one annual tax certificate sale in every county, on the third Monday of December between 9 a.m. and 4 p.m. at the courthouse. State law directs the treasurer to offer at public sale at the courthouse a tax certificate for any real property that is liable for taxes for the preceding year or years and remains due and unpaid, and lets the sale adjourn from day to day until every certificate has been offered. Brookings County posts no sale notice of its own online, so confirm the hour and the room with the Finance Office at 605-696-8250 before the December date.
Registration and deposit

Bidding is in person and there is no online or telephone bidding and no online bidder registration. State law places the sale at the courthouse, and the Finance Office that conducts it sits at 520 3rd St, Suite 100 in Brookings. The county publishes no bidder packet or deposit schedule, so call 605-696-8250 ahead of the December sale to confirm the room, the identification and taxpayer identification number the office wants, and the accepted form of funds. A bidder wins by naming the lowest annual interest rate while paying the full delinquent tax, interest and costs, and a parcel whose winning bidder fails to pay is offered again.

Sale format and venue
South Dakota certificates are bid down on the interest rate, never up on price. The amount paid is fixed at the full delinquent tax, interest and costs, so no premium is possible and bidders compete only by naming a lower annual rate, with the lowest rate winning the certificate. State law makes any bid above 10 percent a year invalid and sets no minimum, so a certificate on a contested parcel can be bid all the way down to zero, leaving the winner with the lien but little or no interest. Interest accrues on the certificate amount at the rate bid, and later taxes the holder pays earn the same rate from the date of payment. Certificates that draw no bidder at the December sale stay available afterward at the Finance Office, where the treasurer must sell them to anyone who pays the taxes, penalty and costs.

Tax deed sale

Run by
County Treasurer issues the deed; the county then sells the property under SDCL chapter 6-13, commonly through the county auditor
Frequency
as needed
Typical timing
There is no fixed annual date.
Registration
Set county by county.
When it runs
There is no fixed annual date. A tax deed sale happens parcel by parcel once a tax deed has issued. The certificate holder, which in most counties is the county itself, may begin the deed process no sooner than three years and no later than six years after the certificate sale by serving a notice of intention to take a tax deed. Sixty days after the affidavit of completed service is filed with the treasurer, redemption ends and the treasurer prepares the deed. SDCL 10-25-39.1 then requires the county to declare the property surplus and sell it within one year, with notice published at least twice and the first publication at least thirty days before the sale. Watch the county auditor and the county's legal notices for those publications.
Registration and deposit

Set county by county. SDCL chapter 6-13 lets the county take sealed bids opened at a commission meeting, sell at public auction to the highest bidder, or list the property with one or more licensed real estate brokers, and it prescribes no bidder registration. Sealed bids are filed with the county's fiscal officer and opened at the time named in the published notice. The board may reject every bid, but if it accepts one it must be the highest. A county may refuse a bid from any person who is not current on all property taxes due within that county. No deposit is required on a cash sale; a buyer taking an installment contract deposits the cash portion as soon as the bid is accepted, and gets it back if the board declines to approve the sale. Confirm the bid form, the deadline and the payment terms with the county auditor.

Sale format and venue
This is the sale most South Dakota bidders can actually take part in, and it is a sale of the property itself rather than of a lien. Costs of taking the deed and of the sale come out of the proceeds first, the remainder is prorated to the taxing districts until all tax and interest is paid, and any surplus goes back to the prior owner of record, or to the Unclaimed Property Division if that owner cannot be found within one hundred eighty days. A private certificate holder who takes a tax deed is under the same duty: SDCL 10-25-39.2 requires that holder to offer the property at public auction within one year and entitles the holder only to what a redemption would have paid. Title vests in fee simple but remains subject to any claim the state or county has for taxes, liens or encumbrances and to past-due installments of municipal special assessments, and counties commonly convey by quitclaim deed and expect the buyer to bring a quiet title action. The former owner has one hundred eighty days after the deed is recorded to sue to recover possession or to avoid the deed.

Brookings County tax sale list and auction calendar

For Brookings 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

    A county sale-list URL is still being verified. Use the office and platform details on this page before relying on a copied list.

  2. Register to bid

    Set county by county. Full requirements are in the sale card above.

  3. Sale day

    There is no fixed annual date. 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 County Treasurer issues the deed; the county then sells the property under SDCL chapter 6-13, commonly through the county auditor as the source to confirm which parcels are actually offered.

Before you bid in Brookings County

  1. Start with the live sale list

    The county sale-list URL is still being verified. Use the county office contacts below and confirm the advertised parcels directly before you price a bid.

  2. Confirm registration and deposit

    Set county by county. SDCL chapter 6-13 lets the county take sealed bids opened at a commission meeting, sell at public auction to the highest bidder, or list the property with one or more licensed real estate brokers, and it prescribes no bidder registration. Sealed bids are filed with the county's fiscal officer and opened at the time named in the published notice. The board may reject every bid, but if it accepts one it must be the highest. A county may refuse a bid from any person who is not current on all property taxes due within that county. No deposit is required on a cash sale; a buyer taking an installment contract deposits the cash portion as soon as the bid is accepted, and gets it back if the board declines to approve the sale. Confirm the bid form, the deadline and the payment terms with the county auditor.

  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

  • Brookings County has no Treasurer. In 2008 the county combined the Treasurer's Office and the Auditor's Office into a single Finance Office, and that office collects property taxes for the county, city and school districts and runs the December tax certificate sale. Anyone looking for a Brookings County Treasurer should contact the Finance Office at 520 3rd St, Suite 100, Brookings, SD 57006, phone 605-696-8250, open 8 a.m. to 5 p.m. Monday through Friday.
  • The county publishes no delinquent list or sale calendar on its website. South Dakota requires the treasurer to publish notice of the sale once during the week before the sale in the county's official newspapers, and to mail notice to the owner, so the printed legal notices carry the Brookings parcel list. Ask the Finance Office which newspapers run the county's legal notices and request the list directly as December approaches.
  • A Brookings certificate is a lien, not title. Anyone may redeem at any time before a tax deed issues by paying the certificate amount with interest at the rate bid, plus any later taxes the holder paid with interest at the same rate. The holder cannot begin a deed proceeding until three years after the sale, must then serve a notice of intention to take a tax deed on the owner, the occupant, mortgagees, lienholders and other interested parties of record, and the right of redemption expires 60 days after that service is complete.
  • The certificate expires. If the deed proceeding is not completed within six years of the sale date, the certificate, the tax lien and the lien for any subsequent taxes the holder paid all cease and are forever barred, and the Finance Office cancels the certificate. Weigh the three-year wait and the notice work against that six-year outside limit before bidding.
  • Research parcels before the sale. The county links a Beacon parcel map carrying ownership, address, recent sales and zoning information, and the Register of Deeds at 520 3rd St, Suite 120, phone 605-696-8240, holds the recorded deeds, mortgages and liens that a notice of intention must reach. Delinquent taxes in Brookings County carry a 10 percent annual penalty, the same ceiling state law places on a tax certificate bid.

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.

Frequently asked questions

Does Brookings County, South Dakota sell tax liens or tax deeds?

Brookings County follows South Dakota's tax lien state system.

When is the Brookings County tax certificate sale?

South Dakota sets one annual tax certificate sale in every county, on the third Monday of December between 9 a.m. and 4 p.m. at the courthouse. State law directs the treasurer to offer at public sale at the courthouse a tax certificate for any real property that is liable for taxes for the preceding year or years and remains due and unpaid, and lets the sale adjourn from day to day until every certificate has been offered. Brookings County posts no sale notice of its own online, so confirm the hour and the room with the Finance Office at 605-696-8250 before the December date. The sale is held in person. Always confirm the exact date with the County Treasurer before the sale.

How often does Brookings County hold tax deed sales?

Brookings County holds its tax deed sale as needed. There is no fixed annual date. Each sale is scheduled and advertised in advance, so check the county's tax deed calendar for the next posted date.

I own a property in this sale. Can I stop it?

Often yes, by paying the overdue taxes, interest, and costs before the deadline. South Dakota's redemption rule: Open until a tax deed issues; a deed cannot be sought until 3 years after the certificate sale, and redemption then runs until 60 days after completed service of the notice of intention. Call the County Treasurer issues the deed; the county then sells the property under SDCL chapter 6-13, commonly through the county auditor as early as possible for your exact payoff and options; deadlines are strict.
