In the United States, federal taxes on large estates primarily revolve around the federal estate tax, but it's important to understand how it interacts with other transfer taxes like the gift tax and generation-skipping transfer tax, and how inherited assets are treated for income tax purposes.
The Federal Estate Tax
The federal estate tax is a tax on the right to transfer property at death. It applies only to very large estates, with a substantial exemption amount. For 2025, the federal estate tax exemption is $13.99 million per individual. This means that an individual's estate is generally only subject to federal estate tax if its total value exceeds this amount. For married couples, with proper planning, this exemption can effectively double to $27.98 million.
The tax is levied on the "taxable estate," which is the gross estate (all assets owned or controlled at death, including real estate, bank accounts, investments, and life insurance) minus allowable deductions (such as debts, administrative expenses, and charitable bequests, or transfers to a surviving spouse). The federal estate tax rates are progressive, ranging from 18% to 40%, with the top rate applying to the largest estates. It's crucial to note that the estate itself pays this tax before assets are distributed to beneficiaries, not the heirs directly.
Important Note for 2026 and Beyond: The current estate tax exemption amounts are set to "sunset" at the end of 2025. Unless Congress acts, the exemption amount is projected to revert to approximately $7 million per individual (adjusted for inflation) in 2026. This significant change could bring many more estates into the federal estate tax's purview.
Gift Tax: The Unified System
To prevent individuals from avoiding estate tax by giving away all their wealth during their lifetime, the U.S. has a federal gift tax. The gift tax and estate tax operate under a unified system. The same lifetime exemption amount that applies to the estate tax ($13.99 million for 2025) also applies to gifts made during one's lifetime.
While there's a lifetime exemption, there's also an annual gift tax exclusion. For 2025, an individual can give up to $19,000 per person per year to as many recipients as they wish, without it counting against their lifetime exemption or requiring a gift tax return. Married couples can combine their annual exclusion to $38,000 per recipient. Gifts exceeding the annual exclusion amount will reduce the donor's lifetime exemption.
Generation-Skipping Transfer (GST) Tax
The Generation-Skipping Transfer (GST) tax is an additional federal tax designed to prevent individuals from avoiding transfer taxes (estate and gift taxes) by transferring assets to beneficiaries two or more generations younger than themselves (e.g., grandchildren or great-grandchildren), thereby "skipping" a generation for tax purposes.
The GST tax applies in addition to the estate or gift tax. It has its own exemption amount, which is generally unified with the federal estate and gift tax exemption ($13.99 million for 2025). Transfers exceeding this GST exemption are taxed at a flat rate, currently 40%, which is the highest federal estate and gift tax rate.
Income Tax on Inherited Assets
It's important to distinguish between estate taxes and income taxes on inherited assets. Generally, inherited property itself is not subject to federal income tax to the recipient. This is because inherited assets usually receive a "stepped-up basis" to their fair market value on the date of the decedent's death. This means that any unrealized capital gains that accrued during the decedent's lifetime are effectively eliminated for income tax purposes.
However, any income generated by inherited assets after they are received (e.g., interest from inherited bank accounts, dividends from inherited stocks, or rental income from inherited real estate) is subject to regular income tax for the beneficiary. If inherited assets are sold for a gain after the date of death, capital gains tax may apply to that post-death appreciation.
Conclusion
Federal taxes on large estates in the U.S. are primarily governed by the federal estate tax, which works in conjunction with the gift tax and generation-skipping transfer tax to create a comprehensive system for taxing wealth transfers. While these taxes only impact a small percentage of the wealthiest Americans due to high exemption amounts, effective estate planning is crucial for those with significant assets to minimize potential tax liabilities and ensure their legacy is distributed according to their wishes. Given the projected changes to the exemption amounts in 2026, individuals with substantial estates should review their estate plans with legal and financial professionals to understand the potential impact.
