The Good News: Missouri Has No Estate Tax

Let’s start with the bottom line. Missouri does not have a state estate tax, and it does not have an inheritance tax. Missouri repealed its estate tax years ago, and it has never had an inheritance tax. So when you pass, your estate owes no death tax to the State of Missouri, and your heirs owe no Missouri tax simply for inheriting from you.

That puts Missouri families in a better position than residents of the handful of states that still impose their own estate or inheritance taxes. For the vast majority of St. Charles County families, state-level death tax simply isn’t a concern.

What About Federal Estate Tax?

There is still a federal estate tax — but it only affects very large estates. For 2026, the federal estate tax exemption is $15 million per person, which means a married couple can generally pass roughly $30 million before any federal estate tax applies. Anything above the exemption is taxed at 40%, but only the amount over the line. This exemption was made permanent under recent federal law and adjusts for inflation going forward.

In plain terms: unless your estate is worth well into eight figures, federal estate tax almost certainly doesn’t apply to you. The overwhelming majority of families fall far below the threshold.

So If It’s Not About Taxes, What Should You Worry About?

Here’s the key shift in thinking. Because state death tax doesn’t exist in Missouri and federal estate tax only touches the very wealthy, taxes are not the reason most families need estate planning. The real risks are the ones we see every day:

• Probate — the slow, public, costly court process your family goes through without the right plan.
• Incapacity — what happens if you’re alive but can’t make decisions, and no one has authority to act.
• Family conflict — the disputes that erupt when your wishes aren’t clear and in writing.
• Lack of control — assets handed to heirs outright with no protection from divorce, creditors, or poor decisions.
• Long-term care costs — nursing home expenses that can drain an estate faster than any tax.

These are the things that actually cost Missouri families money, time, and peace — not estate tax. A good plan is built around these risks.

Don’t Confuse Estate Tax With Other Taxes

A couple of clarifications, since this is where confusion creeps in. Estate tax is different from income tax (your heirs generally don’t pay income tax on an inheritance itself, though inherited retirement accounts have their own income-tax rules). It’s also different from capital gains tax, which can matter when heirs later sell inherited property — and which is actually one area where good planning, like the “step-up in basis,” can help your family. The point: “Missouri has no estate tax” is great news, but it doesn’t mean taxes never enter the picture. The details are worth a conversation.

When Estate Tax Planning Does Matter

For a minority of families — those with estates approaching or exceeding the federal exemption, or who own rapidly appreciating assets, businesses, or significant life insurance — federal estate tax planning genuinely matters, and there are powerful strategies to reduce or avoid it. If that might be you, it’s worth a focused conversation, because the planning is most effective when done early. But for most St. Charles County families, the message is simple: don’t let estate-tax fears drive your planning. Focus on the risks that actually apply to you.
