Federal Estate Taxes

The federal estate tax affects only the richest families in America.

Updated by , Attorney George Mason University Law School
Updated 7/07/2025

The federal estate tax affects only the richest families in America. For deaths in 2025, only estates worth more than $13.99 million ($15 million for deaths in 2026) will owe estate taxes. And married couples can share their exemptions—so between them, they can leave up to $27.98 million ($30 million in 2026) with no concern about estate taxes.

In July 2025, the One Big Beautiful Bill Act was signed into law. This act raised the estate and gift tax exemption from $13.99 million to $15 million ($30 million for married couples) beginning in 2026. This amount will be adjusted for inflation every year after 2026.

Amount Exempt From the Estate Tax

Every person who dies in 2025 may leave or give away up to $13.99 million ($15 million in 2026) without owing any estate tax. As a practical matter, that means that under the current rules, about 99.9% of all estates will NOT owe any federal gift/estate tax.

Here are the federal estate tax exemption amounts in recent years:

2026 $15 million
2025 $13.99 million
2024 $13.61 million
2023 $12.92 million
2022 $12.06 million
2021 $11.7 million
2020 $11.58 million
2019 $11.4 million
2018 $11.18 million
2017 $5.49 million
2016 $5.45 million
2015 $5.43 million

‘Portability' Allows Spouses to Combine Exemptions

One popular feature of the current estate tax law is that spouses can combine their estate tax exemptions, effectively letting married couples give away or leave $27.98 million ($30 million in 2026) without owing tax. The law makes this feature, called "portability" by tax experts, permanent.

Here's how it works: If the first spouse to die doesn't use up their individual gift and estate tax exemption, the surviving spouse can use what's left. That gives the couple a total exemption of twice the individual exemption amount. They can share that total exemption amount in the way that provides the greatest tax benefit. For example, if each member of a couple has $10 million in assets, and the first one to die leaves everything to the other, no estate tax is owed because property left to a spouse is tax-free. When the survivor dies and leaves $20 million ($10 million plus the $10 million inherited from the other spouse) to their children, no estate tax will be due, even though the estate is over the exemption amount, because the estate can use some of the first spouse's unused exemption.

To take advantage of the portability rule, an estate tax return must be filed to claim portability—even if no tax will be due. As commentators have pointed out, this means the IRS must process returns that don't provide any tax revenue, and taxpayers must pay experts to prepare these very complicated tax returns.

In 2023, the IRS extended the deadline for claiming portability to five years after the first spouse's death.

Gift and Estate Tax Rates

On very large estates subject to the tax, the gift/estate rate is now 40%. (Historically speaking, this rate is relatively low.)

This rate also applies to the generation-skipping transfer tax. The generation-skipping transfer tax is a federal tax that's imposed on large transfers that skip a generation (for example, a gift from a grandparent to a grandchild) in an attempt to avoid estate tax.
