If you’re wondering how inheritance tax might affect what you leave behind, 2026 brings some clear numbers to keep in mind. In the US, inheritance tax rules can seem confusing, but knowing the thresholds, rates, and ways to reduce your tax bill can help you protect your family’s legacy.

What Is Inheritance Tax?

Inheritance tax is a tax on money or property you pass on after you die. In the US, it’s usually the estate — everything you own at the time of your death — that’s taxed before it goes to your heirs. The estate includes things like your home, bank accounts, investments, retirement accounts, life insurance policies (if you owned them), and personal belongings.

But not everyone pays this tax. It only applies if your estate is worth more than certain amounts, called thresholds or exemption limits. If your estate is below these limits, your heirs won’t owe any federal inheritance tax.

Inheritance tax works like a toll you pay when you leave behind a large inheritance. If your package is small, you don’t pay the toll.

But if it’s big — say a house, several bank accounts, and valuable investments — you’ll need to pay a percentage on the part that’s over the limit. This tax is often called the federal estate tax, but it functions like an inheritance tax because it reduces what your heirs receive.

Also, keep in mind that some states have their own inheritance or estate taxes with different rules. For example, states like Maryland and Nebraska impose inheritance taxes, while others like New York and Massachusetts have their own estate taxes with lower exemption amounts than the federal government. So, depending on where you live, you might face additional taxes on your estate.

How Do the 2026 US Inheritance Tax Thresholds and Rates Work?

For 2026, the federal estate tax exemption amount — the threshold before you owe any tax — is $12.92 million per person.

This means if your entire estate is valued below $12.92 million, your heirs won't owe any federal inheritance tax.

Married couples can combine their exemptions to protect up to $25.84 million from federal estate tax. This is done through a process called "portability," which allows the surviving spouse to use the unused exemption of the deceased spouse, effectively doubling the amount that can be passed tax-free.

Once your estate’s value goes above this threshold, the amount above $12.92 million is taxed at a steep rate of 40%. So, if your estate is worth $13 million, you’d only pay tax on $80,000 — that’s $13 million minus $12.92 million — at 40%, which equals $32,000.

Because the tax rate is high, you need to plan carefully if your estate is near or above the exemption limit. Without planning, a large portion of your wealth could go to taxes rather than your heirs.

Also, the $12.92 million exemption amount is adjusted annually for inflation, so it typically rises each year. For example, in 2025, the exemption was approximately $12.06 million, so the 2026 increase reflects inflation adjustments keeping pace with the cost of living.

How Is Inheritance Tax Calculated?

Calculating inheritance tax starts with figuring out the total value of your estate at the time of your death. This includes:

  • Your home and other real estate.
  • Cash and bank accounts.
  • Investment accounts like stocks and bonds.
  • Retirement accounts such as IRAs and 401(k)s (though these have special rules).
  • Life insurance payouts if you owned the policy.
  • Personal belongings like jewelry, art, vehicles, and collectibles.

Once you add it all up, the total is called the “gross estate.” From this, you subtract debts and expenses related to your passing, like outstanding mortgages, credit card balances, funeral expenses, and administration costs. These deductions bring you to the “net estate.”

There’s one more wrinkle: any gifts you made in the three years before your death might be added back into your estate value for tax purposes. This is to prevent people from giving away assets shortly before dying to avoid taxes.

Finally, the net estate is compared against the exemption amount — $12.92 million in 2026. Only the value exceeding that gets taxed, and the tax rate is 40% on that excess amount.

For example, if your estate’s net value is $15 million, the taxable portion is $2.08 million ($15 million minus $12.92 million). The tax due would be 40% of $2.08 million, which is about $832,000.

Remember, the estate tax comes out of the estate before your heirs get their share. This means your beneficiaries receive their inheritance after the tax is settled.

What About Gifts and Exemptions?

Many people try to give away money or assets while they're alive to shrink their estate and reduce future taxes. So, there are specific rules about gifts that help reduce tax bills.

  • Annual Exclusion: In 2026, you can give up to $17,000 per year to as many people as you want without those gifts counting against your lifetime estate tax exemption. This means you could give $17,000 to each of your children, grandchildren, friends, or others every year without any tax consequences or reducing your $12.92 million exemption.
  • Lifetime Gift Exemption: Gifts over the annual exclusion amount count toward your lifetime exemption. This lifetime exemption is tied to the $12.92 million estate tax exemption — meaning if you use some of it during your life for gifts, it reduces what you can pass tax-free at death.
  • Gift Tax Rate: Gifts over the annual exclusion and lifetime exemption are taxed at the same 40% rate as estate tax.

For example, if in 2026 you give a $50,000 gift to your child, $17,000 is excluded from tax, but $33,000 counts against your lifetime exemption. If you haven't used any of your lifetime exemption before, you’d reduce it from $12.92 million to about $12.887 million.

Giving gifts is a powerful way to lower your estate’s taxable amount but requires careful record-keeping and planning. There are also special rules for gifts to spouses (which are generally unlimited and tax-free), and for contributions to charities, which can reduce taxes even further.

Besides gifts, trusts are another tool you can use to manage your estate and reduce taxes. Certain types of trusts let you transfer assets out of your estate, protect your wealth, and control how your money is distributed after you’re gone.

Knowing these numbers and options for 2026 means you can plan better and protect your family’s future. Start early, monitor your estate’s value, and use gifts, trusts, and charitable giving to reduce potential taxes. That way, more of what you’ve worked for ends up with the people you care about.
