My Missouri Property Taxes Were Sold — What Happens Now?

The wrong move is to freeze. The clock that protects you also runs against you, and the buyer has steps they must take before they can ever turn that certificate into ownership. This guide walks you through what just happened, how much time you really have, and exactly what to do next so you can redeem your property before that window closes.

First, figure out which law your county used

Missouri runs tax sales under two very different systems, and your rights depend on which one applies to you. Confirm this before anything else.

• Chapter 140 — the Jones-Munger Act. Most Missouri counties use this. The county collector holds an annual delinquent-tax sale (traditionally in late August), and the winning bidder gets a certificate of purchase. This is the system this guide mostly describes.
• Chapter 141 — the Land Tax Collection Act. The largest charter jurisdictions — the City of St. Louis, Jackson County, and Kansas City — use this instead. It is a judicial process that runs through a land-tax court, and its redemption rules are different and generally shorter.

Call your county collector's office and ask plainly: "Was my property sold under Chapter 140 or Chapter 141?" The answer changes your deadlines, so don't guess.

Understand what the buyer actually got

It helps to know that the person who "bought" your taxes did not buy your house. Under Chapter 140, they bought a certificate of purchase — essentially the right to collect what you owe, plus interest, or eventually to apply for a deed if you never redeem.

• They cannot move in or sell your home. A certificate is not a deed. The buyer holds it and waits while your redemption period runs.
• They are owed the back taxes plus interest and costs. Their return comes from you redeeming (paying them back with interest) or, failing that, from getting a deed down the road.
• They must clear legal hurdles first. Before the buyer can ever receive a collector's deed, they have to give you proper statutory notice and a real chance to redeem. Skip that, and the deed can be defeated.

In other words, the auction started a process — it did not finish one.

Know your redemption window — and use it

This is the reassuring part. Under Chapter 140, for a property's first or second offering, you generally have a one-year redemption period after the sale (RSMo § 140.340). During that year you can reclaim your property by paying what's owed.

• What you pay to redeem. Generally the delinquent back taxes, the interest the law allows, and the purchaser's costs. The collector calculates the exact figure.
• Where the year runs. The one-year clock typically runs from the date of the sale for a first- or second-offering property. (A property offered a third time carries a much shorter window, so confirm which offering yours was.)
• Redeem in full to keep your home outright. Paying the full redemption amount within the period cancels the buyer's certificate and clears the sale — you keep the property.

Mark the deadline on your calendar the day you learn the sale happened. Time is the one thing you can't get back.

Contact the county collector right now

You cannot redeem on a guess. The county collector is the office that holds the money, knows the numbers, and gives you the official payoff. Make this your first call.

• Ask for the exact redemption amount. Request a written redemption quote — taxes, interest, and costs through a specific date. The number grows as interest accrues, so ask what it will be on the day you plan to pay.
• Confirm your deadline in writing. Get the collector to confirm the last day you can redeem and the offering number (first, second, or third), since that controls how long you have.
• Pay the way they require. Collectors often want certified funds (cashier's check or money order). Ask about accepted forms of payment and get a dated receipt.
• Keep every record. Save the receipt and any redemption certificate the collector issues. That paper is your proof that the sale is undone.

If you can't pay the full amount at once, tell the collector and ask what options exist — and get advice quickly, because waiting shrinks your choices.

Watch the mail — the buyer must give you notice

Here is a protection many owners don't know they have. Before the purchaser can receive a collector's deed, they must give you statutory notice and a chance to redeem under RSMo § 140.405. This notice usually arrives near the end of your redemption period, and it matters enormously.

• Open and date every certified letter. A notice that you're about to lose the right to redeem is not junk mail — it is your final warning and your deadline.
• Defective notice can save your property. If the purchaser fails to give the notice the statute requires — wrong address, late, missing parties, or skipped entirely — the resulting deed can often be challenged and set aside. This is one of the most common ways owners defeat a tax deed.
• Don't rely on a defect; redeem if you can. Faulty notice is a backstop, not a plan. If you have the money, redeem and end the matter cleanly. Save the notice argument for when redemption truly isn't possible.

If you can't redeem, get advice fast

Sometimes the redemption amount is out of reach, or the deadline is bearing down. Don't disappear — that's when people lose homes they could have kept.

• Talk to a Missouri attorney about your specific facts. Tax-sale deadlines are technical and short. A lawyer can confirm which chapter applies, calculate your real deadline, and spot a defective notice or process you can challenge.
• Explore ways to raise the redemption funds. A loan, refinance, family help, or a sale of the property before the deed issues can let you walk away with equity instead of nothing.
• Challenge any flawed process. If the sale itself was improper, or the RSMo § 140.405 notice was defective, you may be able to ask a court to undo the deed. These challenges are time-sensitive, so move before the deed is recorded if you possibly can.

The earlier you act, the more options stay open. Almost everything gets harder once a collector's deed is issued and recorded.
