Registration and deposit

There is no online bidder registration for this sale. Bidding is done in person at the courthouse in Milbank on sale day. Call the Treasurer's office at (605) 432-5651 ahead of the third Monday in December to confirm certificates are being offered to outside bidders this year, what the office asks of bidders, and which forms of payment are accepted.

Sale format and venue
Bidding is by lowest interest rate, not by price. Every bidder offers the same fixed amount, the full delinquent tax, interest and costs on the parcel, and competes by naming the lowest annual interest rate they will accept. The lowest rate wins and no bid above ten percent per year is valid. South Dakota sets no minimum rate, so a contested parcel can be bid down toward zero, and the winning rate caps the interest for the life of the certificate. Because the purchase price is fixed by statute, there is nothing to overbid and no premium is paid. On redemption the county may deduct a fee of up to fifty dollars, set by county commission resolution, from the proceeds paid to the certificate holder.

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

Typical timing

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.

Grant County tax sale list and auction calendar

For Grant 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 Grant 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

  • Confirm before you travel that certificates will actually be offered. A South Dakota county may not sell a tax certificate to a private bidder unless its board of county commissioners has adopted a resolution waiving the statutory prohibition on those sales. Where no such resolution is in force, the Treasurer bids the parcels off in the name of the county and the county keeps the certificate, while still publishing notice and running the rest of the sale process. The Grant County Treasurer's office can tell you which applies this December.
  • The list of certificates to be offered is published once during the week before the sale in the county's official newspapers. It names the time and place of the sale, each parcel, the party the taxes are assessed against or the current owner of record, and the amount of taxes due. The county does not post that list on its own website, so request a copy from the Treasurer's office or watch the local legal notices.
  • Certificates that draw no bidder at the December sale can be bought afterward at private sale at the Treasurer's office by anyone paying the taxes, penalty and costs due on the property. Certificates the county took in its own name may instead be assigned to a buyer who pays the taxes, penalty, interest and costs of sale plus every unpaid and subsequent tax.
  • Redemption stays open a long time. The owner or any interested party may redeem at any point before a tax deed issues, paying the amount listed in the certificate with interest at the rate the property sold at from the date of purchase, plus any later taxes the holder paid and interest on those at the same rate.
  • A deed proceeding cannot begin until three years after the certificate sale. The holder then serves a notice of intention to take a tax deed on the owner of record, the person in possession and the person in whose name the property is taxed, by personal service, with other interested parties served by registered or certified mail or by publication once a week for two successive weeks in the county's legal newspapers. Redemption does not close until sixty days after the affidavit of completed service is filed with the Treasurer.
  • The certificate has an expiry date. A deed proceeding must be started within six years of the certificate sale and completed within six months after that period runs out, or the Treasurer cancels the certificate and the lien is extinguished. A buyer who takes assignment of a county-held certificate gets one year from the date of assignment to start the proceeding and six months after that year to finish it.

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.
