Check the state rules that change the bid

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
unsold liens and deeds
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.

Tax Collector (runs the certificate sale)
County notes
- The delinquent tax certificate list is the newspaper notice, run in The Warren County Record of Warrenton on July 16, July 23 and July 30, 2026, and posted as a PDF on the Collector's Tax Information page under the heading Tax Sale Information.
- The sale room is Suite 103 on the lower level of the Warren County Administration Building at 101 Mockingbird Lane, one floor below the Collector's counter in Suite 200, so the office and the auction share a building.
- Each tract total in the notice covers taxes, late payment penalty, interest, fees including the cost of the sale, and miscellaneous assessments, and it is the amount that would be due at sale time if nothing further is paid beforehand.
- The Collector's office runs Monday through Friday, 8:00 a.m. to 4:30 p.m., with a 24 hour drop box to the right of the entrance. Julie Schaumberg has served as Collector of Revenue since March 1, 2015.
- Tax statements go out the first week of November and turn delinquent after December 31, so a parcel reaching the August certificate sale has already carried at least one full delinquent cycle.
Missouri rules
- 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.
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.
