Montana Estate Tax

Montana does not levy an estate tax. It is one of 38 states without an estate tax.

What Is the Estate Tax?

The estate tax applies to estates of people who have recently died. The estate tax applies before the assets in an estate are passed on to a person’s designated heirs. It is sometimes called the “death tax,” and it only applies to estates that reach a certain threshold. This threshold is legally determined by the state or other entity levying the tax.

The inheritance tax is different from the estate tax. Inheritance tax applies to inherited assets after distribution to beneficiaries.

Montana Inheritance and Gift Tax

Montana also has no inheritance tax. Be careful, though: You may owe inheritance taxes in another state if someone living in a state with an inheritance tax leaves you property or assets. In Kentucky, for instance, there is an inheritance tax law that applies to all property located in the state, even if the beneficiary lives in another state. Make sure to check local laws whenever you receive an inheritance from someone who lives in different state to avoid accidentally missing a tax bill.

Montana does not have a gift tax either. There is a $18,000 exemption per recipient for the federal gift tax in 2024, up from $17,000 in 2023. If you give more than $18,000 to a single person in a year, though, you must report the gift to the IRS. The amount over the exemption counts towards your $13.61 million lifetime gift tax exemption and lowers your federal estate tax exemption.

Federal Estate Tax

Though Montana won’t tax your estate, the federal government may if it is worth enough. The exemption for the federal estate tax is $13.61 million in 2024, up from $12.92 million in 2023. The federal exemption is portable, so a married couple who takes the right legal steps can protect up to $27.22 million of their estate when they both die.

Estates exceeding the exemption are taxed according to an ascending series of rates, which top out at 40%.

Here’s how it works: Consider an estate worth $14.43 million. Subtract the $13.61 million exemption, which leaves you with a taxable estate of $820,000. That puts you in the second-highest tax bracket. You’ll owe a base payment of $248,300 on the first $750,000. You also must pay a 39% tax on the $70,000 in the tax bracket, which totals $27,300. Add that to the base rate and you get a total estate tax burden of $275,600.
