Inheritance Laws in Missouri (2026): Your Family’s Money, Explained Simply
Most people only think about inheritance laws when it’s too late. Seriously. By then, families are already stressed, confused, and sometimes fighting over who gets what. Don’t let that happen to you.
Missouri’s inheritance laws are actually pretty straightforward once you break them down. This guide covers everything you need to know, from what happens when there’s no will, to taxes, to how to protect your family’s future.
What Is Inheritance Law?
Inheritance law decides what happens to a person’s money, property, and belongings after they die. It covers who gets what, how much they get, and when they get it.
Pretty much every state has its own rules. Missouri is no different. And honestly, knowing these rules ahead of time can save your family a lot of pain.
The Good News: No Missouri Inheritance Tax
Okay, let’s start with something you’ll love. Missouri does not have an inheritance tax. That means when you inherit money or property in Missouri, you don’t owe any state tax on it.
Missouri also eliminated its estate tax back in 2005. So the state won’t take a cut before your loved ones receive their inheritance either. That’s a big deal.
Wait, does that mean zero taxes? Not exactly. Keep reading.
Federal Taxes Still Apply
Here’s where things get a little more serious. Even though Missouri has no state estate tax, the federal government still has one. It only applies to very large estates, though.
In 2026, the federal estate tax exemption is $15 million per person. Thanks to the One, Big, Beautiful Bill Act (OBBBA) passed in July 2025, this higher exemption is now permanent. Married couples can combine their exemptions for a total of $30 million.
If the estate is worth less than $15 million, no federal estate tax is owed. Most families fall well below this number. You’re probably fine.
What If Someone Lives in Another State?
Here’s something most people miss. If you inherit property from someone who lived in a state that has its own inheritance tax, you might owe taxes to that state. Not to Missouri, but to them.
States like Kentucky, Pennsylvania, Iowa, Maryland, Nebraska, and New Jersey all have inheritance taxes. If your aunt in Kentucky left you her house, you might owe Kentucky inheritance tax. Always check the other state’s laws when this happens.
What Happens When There’s No Will?
Hold on, this part is important. When someone dies without a will, Missouri law takes over. This is called dying “intestate.” The state then decides who gets what.
The rules come from Missouri Revised Statutes Section 474.010. They follow a strict family order. It’s not random, but it might not match what the person would have wanted.
Spouse Gets Priority
If you’re married and have no children, your spouse gets everything. Simple.
If you have children, it gets a bit more detailed. Your spouse gets the first $20,000 of the estate’s value, plus half of whatever is left. Your children split the other half.
For example, say an estate is worth $100,000. The spouse gets $20,000 plus half of the remaining $80,000, which is $40,000. Total for the spouse: $60,000. The children split the other $40,000.
What If There’s No Spouse?
If there’s no surviving spouse, the estate goes to the children in equal shares. No children? It goes to parents. No parents? To brothers and sisters.
Missouri law keeps going down the family tree until it finds a living relative. If there is truly no family, the estate goes to the state of Missouri.
The 120-Hour Rule
You’re not alone if you’ve never heard of this one. It confuses a lot of people. Missouri has a survivorship rule. An heir must outlive the deceased by at least 120 hours, which is five days. If they don’t, they can’t inherit.
This rule prevents messy legal issues when two people die close together, like in an accident.
Half-Relatives Get Half
This one surprises people. In Missouri, half-relatives get half the share of full relatives. A half-sibling, for example, would get half of what a full sibling would receive from a parent’s estate.
Stepchildren and stepparents have no inheritance rights under Missouri’s intestate laws unless they were legally adopted.
Making a Valid Will in Missouri
Here’s the good news: you can avoid all of that by making a will. A will lets you decide exactly who gets what. It gives you control.
For a will to be valid in Missouri, it must be in writing. You must be at least 18 years old. You must be of sound mind when you sign it. And it must be signed by two witnesses who watch you sign.
Wondering if you really need one? If you have any property, savings, kids, or strong opinions about who should get your stuff, yes, you need one.
Probate: What It Is and Why It Matters
Probate is the legal process of handling a dead person’s estate. A court oversees it. Bills get paid. Assets get distributed.
If you die without a will, your estate goes through probate. Even with a will, probate is often required. The process can take six months to over a year. It can also cost thousands of dollars in legal fees.
Honestly, avoiding probate is one of the best reasons to do proper estate planning.
How to Avoid Probate
There are a few smart ways to skip the probate process. You can create a living trust, which transfers assets directly to your beneficiaries. You can set up “transfer on death” accounts for bank accounts and investments. You can add a beneficiary to your life insurance and retirement accounts.
These strategies let your loved ones receive assets quickly, without court involvement. It’s worth setting them up.
Spousal Rights: What Missouri Protects
Missouri law protects surviving spouses from being completely cut out of a will. Even if a spouse is left nothing in the will, they can claim what’s called an “elective share.”
A surviving spouse can claim one-third of the estate if there are children, or one-half if there are none. This protects spouses from being disinherited.
Missouri is not a community property state. That means assets you owned before marriage stay yours. Only assets you earn during the marriage may be considered jointly owned.
Gifts During Your Lifetime
Smart estate planning sometimes means giving while you’re alive. The IRS allows you to give up to $19,000 per person per year in 2026 without any gift tax reporting. This is called the annual gift tax exclusion.
Giving money away while you’re alive reduces the size of your estate. It can also bring you joy. You get to see the people you love benefit from your generosity right now.
If you give more than $19,000 to one person in a year, you have to report it. But it only counts against your $15 million lifetime exemption. For most people, that’s still not a problem.
Special Circumstances to Know
A few unique situations are worth flagging. Missouri does not recognize common-law marriages. So if you’ve lived with a partner for years but never officially married, they have no inheritance rights under Missouri law. That’s a big one.
Immigration status does not affect inheritance rights in Missouri. Anyone can inherit, regardless of citizenship status. That’s actually a pretty fair rule.
How to Protect Your Family Right Now
Let’s talk about what you can actually do. Start with a will. It doesn’t have to be complicated. A basic will is better than no will.
Name your beneficiaries on all your accounts. Check your life insurance, retirement accounts, and bank accounts. Make sure the right people are listed. These designations override your will.
Talk to an estate planning attorney if you have significant assets or a complicated family situation. It’s worth the investment.
Store your will somewhere safe. Tell a trusted person where it is. Don’t let it be a mystery after you’re gone.
