Tax certificate sale (lien)

Dallas County Collector of Revenue

Sale list
2026 Tax Sale Properties
When it runs
Held every year on the fourth Monday in August at 10:00 a.m., continuing from day to day until every listed parcel has been offered. The collector's current notice sets the sale for Monday, August 24, 2026 at 10:00 a.m. at the Dallas County Annex Building in Buffalo. Delinquent taxes, penalty, interest and sale costs can be paid up to 10:00 a.m. on sale day to pull a parcel out of the sale.
Registration and deposit

Register in the collector's office and get a bidder number before the sale; nobody bids without one. Every bidder signs a notarized affidavit stating they are not delinquent on tax payments for any property, presented with a driver's license or other government issued ID. Affidavits are available from the collector's office ahead of the sale. Bidders must be Missouri residents. A nonresident must execute a Designation of Resident Agent form and have the resident agent execute an Agent Appointment Acceptance form before the sale. The purchaser must be present to bid. The full purchase price is due at the collector's office by 2:00 p.m. the day of the sale in cash, cashier's check or money order, and failure to pay the amount bid adds a 25 percent penalty on the bid plus a prosecuting attorney fee.

Sale format and venue
Dallas County offers a parcel only after it has been delinquent three years, so the annual list stays short. Bidding opens at the taxes, penalty and cost of sale, plus city taxes and fees on parcels inside city limits, and the winning bidder receives a certificate of purchase that the collector issues, records and mails. First and second offering purchases carry a one year redemption period; third offering purchases carry 90 days. No interest is paid on the surplus bid above the tax amount. The parcel list runs in the Buffalo Reflex for three consecutive weeks before the sale and is also available at the collector's office during office hours. Liens against a parcel are not extinguished at the sale or during redemption, and the collector gives no guarantee on title, liens or encumbrances. In person at the Dallas County Annex Building, 108 S Cedar Street, Buffalo

Tax deed sale

Dallas County Collector of Revenue
Frequency
annual
Typical timing
There is no separate deed auction.
When it runs
There is no separate deed auction. Parcels that have already passed a third offering come back at the same fourth Monday in August sale as subsequent to third offerings, sold under Section 140.260.8 with no redemption period.
Registration and deposit

Same bidder number, notarized non-delinquency affidavit, Missouri residency or resident agent, and same day payment rules as the certificate sale. A subsequent to third offering buyer also pays the cost of recording the deed.

Sale format and venue
A subsequent to third offering purchase conveys with no period of redemption, which is the only route to immediate ownership in this county. A first, second or third offering purchase is a certificate instead: after the redemption period runs, the certificate holder must complete the Chapter 140 requirements, including notice to the owner and recorded claimants and an executed purchaser's affidavit, before the collector will issue a collector's deed. The certificate can be assigned, but only to a Missouri resident who owes no delinquent taxes, and the notarized assignment must be presented to the collector's office for recording with a recording fee. In person at the Dallas County Annex Building, 108 S Cedar Street, Buffalo

Dallas County tax sale list and auction calendar

For Dallas 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.

  1. Get the advertised list

    Use 2026 Tax Sale Properties for the current advertised parcels, then recheck it before the auction.
  2. Register to bid

    Ask the county office how and when to register; many counties close registration days or weeks before the sale.
  3. Sale day

    There is no separate deed auction. 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 Dallas County Collector of Revenue as the source to confirm which parcels are actually offered.

Before you bid in Dallas County

  1. Start with the live sale list

    Pull the current advertised parcels from 2026 Tax Sale Properties. Lists can change before the sale, so recheck the county source before you price a parcel.
  2. Confirm registration and deposit

    Same bidder number, notarized non-delinquency affidavit, Missouri residency or resident agent, and same day payment rules as the certificate sale. A subsequent to third offering buyer also pays the cost of recording the deed.

  3. Check the state rules that change the bid

    Read the Missouri due-diligence checklist before bidding. Redemption, liens that survive a tax deed, title cleanup, and payment deadlines can change what a parcel is worth.
  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

Missouri publishes no standing over the counter certificate list. The equivalent route is the post third offering sale. Parcels that draw no buyer at a third offering must be advertised or offered again once every 30 days, and where the county's appointed trustee declines to take a parcel the collector may sell it at any time and for any amount. A buyer at any of these sales gets an immediate collector's deed, no redemption period, and must first pay every tax that fell due after the taxes named in the advertisement. Parcels the trustee did take are held for the taxing funds and sold on order of the county commission. Ask the collector for the current post third offering list and its bidding terms, because the format varies by county.

County notes

  • The sale is a live, in person auction at the Dallas County Annex Building, 108 S Cedar Street in Buffalo. There is no online bidding platform for this county, and the purchaser must be at the sale to bid.
  • A Bid4Assets page carries a notice announcing this county's live tax lien sale. Treat it as an announcement only. Bids are taken in person by the collector, and registration runs through the collector's office.
  • Office hours are Monday through Friday, 8:00 to 12:00 and 1:00 to 4:00, except holidays, so plan the bidder registration and affidavit visit around that window.

Missouri rules

Max interest rate
10% per year, set by statute (bidding is on price)
Minimum return
No statutory minimum return; what you earn is set by the price at the sale
Redemption
After a first or second offering sale, the owner and other interested parties hold an absolute right to redeem for one year, then a defeasible right that lasts until the purchaser actually acquires the deed. A purchaser must serve the 90 day notice of the right to redeem before the date on which the deed can be acquired, so the practical window usually runs past the one year mark. After a third offering sale, redemption runs 90 days, and the purchaser must give notice to recorded claimants within 45 days of the sale. After a post third offering sale, there is no redemption period and the deed issues immediately. Minors and incapacitated or disabled persons have a longer right, running five years from the last payment of taxes by that person or a predecessor. The right also ends if the certificate lapses because the purchaser failed to record the deed within 18 months.
Deed deposit
The winning bidder must pay the full amount of the bid to the collector immediately at the sale. Chapter 140 sets no advance bidder deposit and no balance due window. A bidder who fails to pay forfeits a penalty of 25 percent of the bid to the county school fund and the parcel is offered again at once as though no sale had been made. Counties running an online or registered sale may impose their own deposit and registration terms on top of the statute, so confirm them with the collector.
Surplus proceeds
Any amount above the taxes and costs is surplus. The collector pays it into the county treasury, where the treasurer holds it in trust for the lesser of three years or 90 days after the redemption period expires. It is distributed first to the former lienholders of record in the priority their liens held on the date of the sale, then to the former owner. No distribution other than through the redemption process may occur until 90 days after the redemption period ends, and a claimant must file a written claim with the county commission within those 90 days, referencing the recorded lien it rests on. The county pays no interest on the fund. Anything still unclaimed at three years becomes the permanent school fund of the county.
Governing statute
Mo. Rev. Stat. Chapter 140

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.
