The Brookings County site carries a Finance Department answer that taxes are due January 1, that the first half is accepted until April 30 without penalty, that the second half is accepted until October 31 without penalty, and that late payments carry a 10 percent annual penalty. The state treasurer directory lists the county office at 520 3rd St. Suite #100 in Brookings with phone (605) 696-8250. The county's published pages do not state whether certificates are sold to the public, and they publish no tax certificate page, no assignment list, no tax deed page, and no surplus land sale of tax deed property.
Selling office: Brookings County Finance Office, 520 3rd St. Suite #100, Brookings, SD 57006, (605) 696-8250
Next sale: The next annual sale date under state law is December 21, 2026, from 9 a.m. to 4 p.m. at the courthouse, for the preceding year's unpaid taxes.. Brookings County has published no 2026 sale date, list, or bidder notice on its own pages. Under SDCL 10-23-2 the treasurer gives notice once during the week before the sale in the official newspapers of the county, so the dated list for December 2026 appears in that newspaper notice rather than on the county site.
Watch the official county newspapers during the week before December 21, 2026 for the statutory sale notice and list, and call the Finance Office at (605) 696-8250 before that week to ask whether the county sells, assigns, or simply holds its certificates.
| Next sale | The next annual sale date under state law is December 21, 2026, from 9 a.m. to 4 p.m. at the courthouse, for the preceding year's unpaid taxes. |
| Taxes due | First half accepted until April 30 and second half until October 31, with a 10 percent annual penalty for late payments |
| Annual sale | December 21, 2026, 9 a.m. to 4 p.m. at the courthouse under state law, with bidding down from a 10 percent per year interest ceiling where a public sale is held |
| Certificate holder | The county holds every certificate unless its commissioners adopted a waiver resolution under SDCL 10-23-28.1 |
| Redemption and deed | The owner may redeem until a tax deed issues. A deed proceeding may start 3 years after the sale and must finish within 6 years. |
| Tax deed land | Land the county takes by tax deed must be declared surplus and sold at public auction within one year of the deed, with any surplus over taxes and costs returned to the prior owner |
| Format | Brookings County publishes property tax payment information through its Finance Office, and its published pages do not state whether tax certificates are sold to the public. State law bars a county from selling certificates unless its commissioners adopted a resolution waiving the ban in SDCL 10-23-28.1, and no waiver, bidder invitation, or assignment offer appears on the county pages found. A buyer therefore has no published Brookings County route to a certificate and should ask the Finance Office directly whether the county holds its certificates or assigns any of them.: In person at the county courthouse in Brookings under the state sale framework, with sale specifics published by newspaper notice under SDCL 10-23-2 |

Sources: Brookings County Frequently Asked Questions. South Dakota Department of Revenue, Contact County Treasurers. SDCL 10-23-28.1, sale of tax certificates prohibited unless waived. Confirm with the selling office before relying on any date on this page: sales move, terms change, and parcels are pulled up to sale day.
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 Brookings County, searchable by address, owner, or county, including parcels that never reach a sale list.

The county publishes no bidder registration rules, no bidder number process, and no assignment request rules for tax certificates.
| Deposit, Brookings County | The county publishes no deposit requirement for a tax certificate sale or for an assignment. |
| Payment, Brookings County | The county does not publish payment terms for buying a tax certificate. Its published payment information covers ordinary property tax payments and the April 30 and October 31 deadlines. |
| Redemption period | Until a tax deed issues. The deed proceeding opens three years after the certificate sale, and a certificate whose proceeding is not completed within six years of the sale is cancelled and the lien forever barred (SDCL 10-25-1 and 10-25-16). |
| Interest on a certificate | For a certificate sold to a private buyer, the rate bid at the sale, never more than 10 percent per year; redemption pays that rate on the certificate sum and on later taxes the holder paid (SDCL 10-23-8 and 10-24-1). A certificate held by the county bears interest at the statutory Category G rate (SDCL 10-23-25). |
| The 2006 certificate rule | No county may sell any tax certificate unless the board of county commissioners adopts a resolution waiving the prohibition in SDCL 10-23-28.1. Absent that waiver the county is the holder of every certificate issued, which is why the channel differs county by county. |
| Buying from the county | An assignment of a county held certificate costs everything owed: the taxes, penalty, interest and costs of the sale and transfer plus all unpaid or subsequent taxes on the parcel, paid in full before the assignment is made (SDCL 10-23-27 and 10-23-28). |
| Deed notice costs | The costs of the deed proceeding notice, including the records search, locating owners and an attorney fee, are capped at $400 in total and are added to the amount an owner must pay to redeem (SDCL 10-25-9). |
| The one year auction and the surplus | A tax deed holder, private or county, must offer the property at public auction within one year of the deed. Sale proceeds beyond the taxes, penalty, interest, county liens and costs are surplus and must be returned to the prior owner of record; unclaimed surplus goes to the Unclaimed Property Division after 180 days (SDCL 10-25-39, 10-25-39.1 and 10-25-39.2). |
| Fees | The treasurer collects $10 for each tax certificate and $5 for each tax deed (SDCL 10-23-19 and 10-25-11). A county commission may set a fee of up to $50, deducted from the holder's proceeds, on redemption of a certificate held by someone other than the county (SDCL 10-23-8). |
| Certificate fee | $10 per certificate under state law |
| Late payment penalty | 10 percent per year, as the county Finance Department publishes |
| Sale notice | Publication once during the week before the sale in the official newspapers of the county under SDCL 10-23-2 |
Unless a waiver resolution was adopted, the county itself holds the certificates it issues under SDCL 10-23-28.1. If the county later takes a tax deed, state law requires it to declare the land surplus and sell it at public auction within one year of the deed, and any surplus over taxes, penalties, interest, and costs goes back to the prior owner under SDCL 10-25-39 and 10-25-39.1.
