Missouri Property Tax Sale: The Three County Systems Explained

A Missouri property tax sale does not follow one statewide rulebook. Missouri runs three separate delinquent tax sale systems, and which one applies to your house depends on the county line it happens to sit inside. A homeowner in Springfield, a homeowner in Kansas City, and a homeowner in the City of St. Louis are each governed by a different chapter of Missouri law.

This is almost never explained at the city level, which is why so many Missouri owners read advice that does not apply to them. This guide covers how your bill is calculated, all three systems and who falls under each, and what you can actually do if your taxes are behind.

How Missouri calculates your property tax bill

Your Missouri tax bill is your assessed value multiplied by the combined levy rate set by your local taxing districts. Assessed value is not market value. Residential real property is assessed at 19% of its market value under RSMo 137.115.5 (Missouri State Tax Commission), so a house the assessor values at $200,000 carries an assessed value of $38,000.

Other classes are assessed differently. Commercial real property is assessed at 32%, agricultural at 12%, and most personal property, including vehicles, at 33.3% (RSMo 137.115.5).

The levy rate is a stack of separate levies from your school district, county, city, fire district, library, and other taxing bodies, added together and applied per $100 of assessed value. Because that stack differs street by street, effective rates vary widely across Missouri, and the only reliable source for yours is your county collector or assessor.

Real property is assessed as of January 1 of each odd-numbered year, so reassessment is biennial rather than annual. Tax bills are typically due by December 31 (LegalClarity, February 2026), and unpaid taxes become delinquent after that.

Missouri's three delinquent property tax sale systems

Missouri uses three different delinquent property tax sale regimes, and the county your house sits in decides which one governs. The default is the Jones-Munger Act. Jackson County, which contains most of Kansas City, uses a judicial alternative. The City of St. Louis, an independent city, uses a third law entirely.

The Jones-Munger Act, RSMo Chapter 140 (sections 140.010 to 140.720), is the statewide default. It is a non-judicial tax sale by publication: the county collector publishes a list of delinquent parcels and conducts the sale without a court reviewing the file first. Most Missouri counties use it, including Greene County, where Springfield sits, and St. Louis County.

The Land Tax Collection Law, RSMo Chapter 141 (sections 141.210 to 141.810), is a judicial process. Chartered class-one counties may elect it, and Jackson County currently does, which means Kansas City owners are in a court proceeding rather than a publication process. One telling detail: St. Louis County formerly used Chapter 141 and switched back to Jones-Munger because judicial foreclosure proved too expensive and time consuming.

The Municipal Land Reutilization Law, RSMo 92.700 to 92.920, governs the City of St. Louis alone. It is built around returning long-vacant and tax-delinquent parcels to productive use, which is a different policy goal than simply collecting the money owed.

Why St. Louis City and St. Louis County follow different rules

The City of St. Louis and St. Louis County are separate jurisdictions running on different tax sale laws, and confusing the two is the single most common mistake Missouri owners make. The city is an independent city, not part of the county. It has its own collector, its own courts, and its own delinquent tax sale statute.

A house inside the city limits is governed by the Municipal Land Reutilization Law (RSMo 92.700 to 92.920). Cross into Kirkwood, Florissant, or Chesterfield and you are in St. Louis County, on the Jones-Munger Act (RSMo Chapter 140). Same metro, different statute.

Deadlines, notice procedures, and the offices you call all differ, and so do market conditions on each side of the line. Our guide comparing selling in St. Louis City versus St. Louis County covers that split in detail, and St. Louis cash buyer options covers what a direct sale looks like locally.

Missouri property tax sale terms, defined

Missouri tax sale notices use a small vocabulary that decides what happens to your house, and the documents rarely define any of it in plain language.

• Assessed value: The taxable portion of your property's market value. For Missouri residential real property it is 19% of market value (RSMo 137.115.5).
• Levy rate: The combined rate set by all local taxing districts that apply to your parcel, applied per $100 of assessed value.
• Delinquent tax lien: A claim the county holds against the parcel itself for unpaid taxes. It attaches to the land, not to you personally, and it must be cleared before clear title transfers.
• Jones-Munger Act: Missouri's default delinquent tax sale law (RSMo Chapter 140), a non-judicial sale by publication used in most counties.
• Land Tax Collection Law: The judicial tax sale alternative (RSMo Chapter 141) that chartered class-one counties may elect, currently used in Jackson County.
• Municipal Land Reutilization Law: The City of St. Louis tax sale and land recovery statute (RSMo 92.700 to 92.920).
• County collector: The county office that bills, collects, and enforces property taxes, and the authoritative source for your payoff amount and sale date.
• Cash home buyer: A company or individual that buys a house directly with its own funds, in its current condition, without a mortgage contingency, and can typically close in days rather than the one to two months a financed sale takes.

Your options when Missouri property taxes are delinquent

Missouri owners with delinquent taxes generally have three practical paths: pay the balance before the sale, sell the house and pay the taxes from the proceeds at closing, or address the taxes alongside a mortgage default if both are running at once. Which fits depends on your cash position, your equity, and how much time the collector's calendar leaves you.

Selling a Missouri house with back taxes owed

You can generally sell a Missouri house that has delinquent property taxes, because the taxes are a lien on the parcel rather than a bar to selling. In a normal closing the title company orders a payoff figure from the county collector, the delinquent taxes are paid out of the sale proceeds, the lien is released, and the buyer takes clear title. The seller nets whatever is left after the taxes, any mortgage payoff, and closing costs.

The constraint is the calendar, not the lien. A sale only helps if it closes before your county's scheduled tax sale, and a financed buyer adds appraisal and underwriting time to that schedule. Missouri houses took a median of 44 days to sell in March 2026 (Redfin, March 2026), before any closing period begins.

Propcash is a direct cash homebuyer. We buy houses across Missouri with our own funds, in any condition, and cash transactions can close in as few as 7 days.

We will also tell you when a cash sale is not your best move. If the tax sale is still months out, the house shows well, and you have real equity, listing with a local agent may net you more, and we will say so and point you to someone local.

Tax delinquency and mortgage default are two separate clocks

A delinquent tax bill and a missed mortgage payment are separate problems, run by different parties, on separate timelines. The county collector enforces taxes under Chapter 140, Chapter 141, or the Municipal Land Reutilization Law depending on your county. Your lender or its trustee enforces the loan under Missouri's deed-of-trust foreclosure rules in RSMo 443.290 through 443.440.

The two do interact. If your loan has an escrow account, the servicer usually pays the taxes and any shortfall lands in your monthly payment. Without escrow, a lender that discovers delinquent taxes may advance them and add the amount to your balance, which can push an otherwise current loan into default.

Owners facing both need to track both dates, because satisfying one does nothing for the other. Our guide to stopping a Missouri foreclosure covers the lender-side timeline and Missouri's conditional redemption rule, and our Missouri cash home buyer page covers statewide options.

Frequently Asked Questions

How does a Missouri property tax sale work?

It depends on the county. Most Missouri counties use the Jones-Munger Act (RSMo Chapter 140, sections 140.010 to 140.720), a non-judicial tax sale in which the county collector publishes a list of delinquent parcels and sells them without going to court. Jackson County uses the Land Tax Collection Law (RSMo Chapter 141, sections 141.210 to 141.810), which runs the same result through a court case. The City of St. Louis uses the Municipal Land Reutilization Law (RSMo 92.700 to 92.920). Confirm which applies to your parcel with your county collector.

What is the Jones-Munger Act in Missouri?

The Jones-Munger Act is Missouri's default delinquent property tax sale law, codified at RSMo Chapter 140, sections 140.010 to 140.720. It is a non-judicial process, meaning the county collector advertises delinquent parcels by publication and conducts the sale without a judge reviewing the file first. It is used in most Missouri counties, including Greene County, where Springfield sits. Because there is no court case to track, owners often learn about the schedule from the published delinquent list rather than from a lawsuit.

Are the City of St. Louis and St. Louis County on the same tax sale system?

No. They are separate jurisdictions on different laws, and this trips up sellers constantly. The City of St. Louis is an independent city governed by the Municipal Land Reutilization Law (RSMo 92.700 to 92.920). St. Louis County runs on the statewide Jones-Munger Act (RSMo Chapter 140). The county formerly used the Land Tax Collection Law in Chapter 141 and switched back to Jones-Munger because judicial foreclosure proved too expensive and time consuming.

How is my house assessed for property taxes in Missouri?

Residential real property in Missouri is assessed at 19% of its market value (RSMo 137.115.5; Missouri State Tax Commission). Commercial real property is assessed at 32%, agricultural at 12%, and most personal property at 33.3%. Your bill is that assessed value multiplied by the combined levy rate set by your local taxing districts, which typically include school, county, city, fire, and library levies. Real property is assessed as of January 1 of each odd-numbered year, so reassessment is biennial.

Can I sell my house in Missouri if I owe back property taxes?

Generally yes. Delinquent property taxes are a lien on the parcel, not a bar to selling it. In a normal closing, the title company orders a payoff figure from the county collector and pays the delinquent taxes out of the sale proceeds, so the buyer receives clear title and the lien is released. What matters is whether the sale closes before the county's scheduled tax sale date. Confirm your exact payoff amount and deadline with your county collector before you sign anything.

Are delinquent property taxes and mortgage foreclosure the same thing in Missouri?

No. They are separate problems on separate clocks, run by different parties under different statutes. A tax sale is run by the county collector under Chapter 140, Chapter 141, or the Municipal Land Reutilization Law, depending on where the house sits. A mortgage foreclosure is run by the lender or trustee under Missouri's deed-of-trust rules in RSMo 443.290 through 443.440. Many owners face both at once, and a lender may advance the taxes and add them to the loan balance, which can push a loan into default on its own.
