What Happens If I Don't Pay Property Taxes in Missouri?

If you don't pay the real property taxes on your Missouri home, you'll likely face a tax sale, which is a public auction. But the winning bidder at the sale doesn't immediately get ownership of the property. Many homeowners will get a year-long redemption period to get caught up on the overdue taxes, penalties, interest, and fees before losing title to the home. However, you might get less time, or no time, depending on the circumstances.

And in limited circumstances, you might be able to set the sale aside (overturn it). But getting a court to set aside a sale doesn't happen very often.

When Are Property Taxes Due in Missouri?

Property taxes in Missouri are due by December 31 each year. (Mo. Stat. § 139.100 (2025).) Tax bills are typically mailed in November, and payments must be made or postmarked by December 31 to avoid penalties.

What Are the Penalties and Interest for Delinquent Property Taxes in Missouri?

In Missouri, if you don't pay your property taxes by the December 31 deadline, penalties and interest will begin to accrue. Missouri law permits 18% per year for interest, plus a 2% penalty. (Mo. Stat. § 140.100 (2025).)

What Is a Tax Lien and How Does It Affect Me?

Property owners are required to pay property taxes, which help fund essential community services such as schools, libraries, public services, roads, and parks. The amount owed is generally determined by the assessed value of the property.

If you have a mortgage, your loan servicer may include property tax payments as part of your monthly mortgage bill. These funds are placed in an escrow account and used to pay your property taxes on your behalf. However, if your taxes aren't handled through an escrow account, you're responsible for paying them directly.

If property taxes go unpaid, the outstanding balance becomes a lien against the property, making the home collateral for the debt. All states, including Missouri, have laws that allow the local government to sell a home through a tax sale process to collect delinquent taxes.

What Are the Legal Consequences of Not Paying Property Taxes?

Again, if you fall behind on your property taxes, a tax lien may be placed on your home. This means the government has a legal claim to your property until the taxes are paid. Each state has its own rules about what happens next, but generally, if the taxes remain unpaid, the government can sell the property, auction off the tax lien, or even foreclose to recover the money owed. Sometimes, the person who buys the tax lien can eventually start the process to sell your home if the debt isn't settled.

State laws also outline important details, like when a tax lien can be placed, how and when a property or lien can be sold at auction, and what steps must be followed to transfer ownership if taxes are still unpaid. There are usually specific rules about how much notice you'll get, how long you have to pay off the debt and keep your home (called a "redemption period"), and how you can claim any extra money if your property sells for more than what you owe. In fact, a recent Supreme Court decision (Tyler v. Hennepin County, 598 U.S. 631 (2023)) made sure that if your property is sold for more than the amount owed, you have the right to claim the extra funds.

Local governments also have their own procedures for running tax sales or foreclosures, including how bids are accepted, what paperwork is needed, and how the money from a sale is divided up. If you ever find yourself facing a property tax issue, it's a good idea to learn about your state and local rules so you know your options and rights.

What Are the Legal Consequences of Not Paying Property Taxes in Missouri?

Under Missouri law, when you don't pay your property taxes, the county collector is permitted to sell your home at a tax sale to pay the overdue taxes, interest, and other charges. (Mo. Stat. § 140.150, § 140.190 (2025).)

A tax sale must happen within three years after the delinquency, but state law permits an earlier sale if the taxes are delinquent. (Mo. Stat. § 140.160 (2025).)

Public Auction

The tax sale consists of a public auction where the collector sells the home to the highest bidder, so long as the highest bid equals or exceeds the amount of the outstanding taxes, penalty, interest, and costs. (Mo. Stat. § 140.190 (2025).)

Delinquent land tax sales begin at 10:00 a.m. on the fourth Monday in August and run from day to day until all parcels are offered for sale. (Mo. Stat. § 140.150, § 140.170, § 140.190 (2025).)

What Happens If No One Bids the Minimum Amount?

If no one bids the minimum amount at the sale, then the collector will hold a second sale the following year. (Mo. Stat. § 140.240 (2025).)

Tax sales are typically held annually. If no one bids the amount of the outstanding taxes, penalty, interest, and costs at the second offering, then the collector will hold a third sale. (Mo. Stat. § 140.250 (2025).) If no one bids at this third sale, the collector is authorized to try to sell it at subsequent sales.

Certificate of Purchase

After a completed Missouri tax sale, instead of getting title to the property after the sale, the purchaser will get a certificate of purchase. (Mo. Stat. § 140.290 (2025).) This certificate is evidence of the purchaser's interest in the property during the redemption period.

Notice Before a Tax Sale Takes Place in Missouri

In most cases, the tax collector must:

• publish notice in a newspaper once a week for three consecutive weeks before the sale (Mo. Stat. § 140.170 (2025)) and,
• before the publication, send a notice by first-class mail, and a second notice by certified mail if the property is worth more than $1,000. (Mo. Stat. § 140.150 (2025).)

How to Stop a Missouri Property Tax Sale

You can prevent the tax sale from taking place by paying the delinquent taxes, penalty, interest, and costs at any time before the sale. (Mo. Stat. § 140.150 (2025).)

Can I Get My Home Back After a Missouri Tax Sale?

Many states give delinquent taxpayers the chance to pay off the amounts owed and keep the home. This process is called "redeeming" the property.

How the Right to Redeem Usually Works

In many states, the homeowner can redeem the home after a tax sale by paying the buyer from the tax sale the amount paid (or by paying the taxes owed), plus interest, within a limited amount of time. Exactly how long the redemption period lasts varies from state to state, but usually, the homeowner gets at least a year from the sale to redeem the property. In other states, however, the redemption period happens before the sale.

In Missouri, the redemption period happens after the tax sale.

How Long Is the Redemption Period After a Mississippi Tax Sale?

In Missouri, you can ordinarily redeem your home within one year after the tax sale and up until the purchaser gets the deed to your home—if the property sells on the collector's first or second sale attempt. (Mo. Stat. § 140.340 (2025).)

If you don't pay off the debt during the redemption period, the purchaser can use the certificate of purchase to apply for and get a collector's deed (title) to your home. (Mo. Stat. § 140.420 (2025).)

Redemption Period If the Home Doesn't Sell at a First or Second Tax Sale

If the home doesn't sell at a first or second sale, the collector will attempt to sell it at a third tax sale. When a home sells at a third tax sale, you get 90 days to redeem the property. (Mo. Stat. § 140.250 (2025).)

No Right to Redeem After a Subsequent Sale

If no one buys the property at the first, second, or third tax sale, but it does sell at a subsequent offering, you don't get a redemption period. (Mo. Stat. § 140.250 (2025).)

Some Homeowners Get More Time to Redeem

Minors, people who are incapacitated, and disabled persons may redeem within five years of the date of the last payment of taxes encumbering the real estate by the minor, incapacitated or disabled person, the party's predecessors in interest, or any representative of such person. (Mo. Stat. § 140.350 (2025).)

How Much You'll Have to Pay to Redeem Your Missouri Home

To redeem your home after the sale, you generally have to pay the following amounts to the county collector:

• the full sum of the purchase money named in the certificate of purchase
• the costs of the sale
• interest at a rate not to exceed 10% per year (but not on the amount the purchaser paid that exceeds the taxes and costs)
• all subsequent taxes that the purchaser paid plus interest, at the rate of 8% per year, and
• certain additional costs. (Mo. Stat. § 140.340 (2025).)

Notice of Your Right to Redeem After a Tax Sale in Missouri

After the sale, you'll receive notice about your right to redeem.

If the home sells at a first or second tax sale. At least 90 days before the date when the purchaser is authorized to acquire the deed, the purchaser must send you a notice by first-class and certified mail about your right to redeem. (Mo. Stat. § 140.405 (2025).)

If the home sells at a third sale. If the property sells at a third sale, the purchaser must send a redemption notice within 45 days of the sale. The 90-day redemption period begins when the purchaser mails this notice. (Mo. Stat. § 140.405 (2025).)

Setting Aside a Completed Tax Sale

In some rare situations, such as if the tax lien or tax sale process has defects, the taxes were paid or not owed, or excusable neglect, you might be able to invalidate a completed tax sale. The reasons that justify, as well as the procedures for, invalidating a tax sale are complicated.

If you lose your home to a tax sale and want to learn more about setting the sale aside, talk with a qualified lawyer as soon as possible.

What Options Do I Have If I Can't Afford to Pay My Property Taxes in Missouri?

Even though you'll probably get a redemption period after a Missouri tax sale, in most cases, it's better to take action before you become delinquent on your taxes to make them more affordable. You could, for example:

• find out if you meet the criteria for a property tax abatement, or
• request a change in the property's assessment if you feel your assessed property value isn't reflective of the fair market value.

Or you might qualify for the Missouri Property Tax Credit, which gives a credit to eligible seniors and 100% disabled persons for a portion of their real estate taxes. Other areas allow eligible seniors to "freeze" the amount of property taxes they have to pay, which prevents future increases.

In addition, some places offer payment plans for paying property taxes. Call the county tax collection office to learn about options where you live.
