Key Facts
- Federal level: The United States has no federal inheritance tax imposed simply because a beneficiary receives inherited property.
- Federal level: Federal law generally excludes the value of inherited property from the beneficiary’s gross income, but income later produced by that property remains taxable.
- Federal level: The separate federal estate tax applies to the transfer of a taxable estate and is calculated at the estate level, not as a flat charge against each beneficiary’s inheritance.
- Federal level: For a U.S. citizen or resident who dies in 2026, the Form 706 filing threshold is $15 million after the statutory combination of the gross estate, adjusted taxable gifts, and specific gift-tax exemption.
- Federal level: Federal estate-tax rates are graduated, and the top statutory rate is 40 percent; that percentage is not a federal inheritance-tax rate applied to the amount an heir receives.
- State level: State inheritance and estate taxes are separate systems, so the tax result can depend on the decedent’s state, the property’s location, and the beneficiary’s relationship to the decedent.
How much is inheritance tax under federal law?
At the federal level, the direct answer is zero: there is no federal inheritance tax charged merely because a person receives money or property from an estate. Internal Revenue Code section 102 generally excludes the value of property acquired by bequest, devise, or inheritance from gross income. That rule explains why receiving an ordinary cash inheritance does not, by itself, create federal income tax for the beneficiary.
The phrase “federal inheritance tax rate” often points to a different tax. The federal estate tax is imposed on the transfer of a taxable estate, and Form 706 calculates the tax on the estate as a whole rather than on each beneficiary’s share. The federal estate tax therefore cannot be converted into a universal percentage that every heir pays.
The 2026 federal estate-tax threshold and rates
For a U.S. citizen or resident who dies during 2026, the federal estate-tax return filing threshold is $15 million. The filing test generally combines the gross estate with adjusted taxable gifts and the specific gift-tax exemption, so it is not simply a comparison between cash left in a will and $15 million. An estate may also file Form 706 below that threshold to elect portability of a deceased spouse’s unused exclusion amount.
The federal rate schedule is graduated rather than flat. Section 2001 reaches a 40 percent top rate on the highest band of the tentative tax computation, but credits and deductions are part of the ultimate calculation. Calling 40 percent “the inheritance-tax rate” is misleading because the estate-tax computation applies to the taxable estate and adjusted taxable gifts, not automatically to the property a particular beneficiary receives.
For example, a 2026 estate with property worth $15 million is not automatically taxed at 40 percent. Filing status, adjusted taxable gifts, allowable deductions, available credits, and portability can change whether a return is required and whether tax is due. This is why the size of an inheritance alone does not reveal the federal estate-tax bill.
What can still be taxable to a beneficiary
The exclusion for inherited property does not turn everything connected with an inheritance into tax-free money. Section 102 preserves federal income tax on income produced by inherited property, including later interest, dividends, or rent. Publication 559 also distinguishes the inherited asset from “income in respect of a decedent,” meaning certain income the decedent had a right to receive before death but that is paid afterward.
An inherited traditional retirement account can produce taxable distributions even though the account passed because of death. Likewise, interest that accrues after inherited cash is placed in an interest-bearing account is the beneficiary’s income rather than another tax-free inheritance. These are income-tax rules, not a federal inheritance-tax rate.
Basis affects tax when inherited property is sold
Inherited property generally receives a basis tied to its fair market value at the date of death, although federal law contains exceptions and alternate valuation rules. Basis is the tax measuring point used to determine gain or loss when property is sold. A later sale can therefore create capital gain or loss even though the initial receipt of the property was excluded from income.
Consider a simplified example in which stock has a date-of-death value of $100,000 and a beneficiary later sells it for $112,000. If the general date-of-death basis rule applies, the potential gain is measured from $100,000 rather than from the decedent’s historical purchase price. The actual basis can differ when a statutory exception, alternate valuation, estate-tax value consistency rule, or special property rule applies.
State taxes require a separate calculation
Federal law does not answer whether a state inheritance tax applies. A state inheritance tax generally focuses on the beneficiary and may vary with the beneficiary’s relationship to the decedent, while a state estate tax generally applies at the estate level. States can set their own exemptions, classifications, rates, filing rules, and connections to property within the state.
Kentucky, for example, administers an inheritance tax with beneficiary classes and exemptions under Kentucky law. That state system does not create a federal inheritance tax and does not establish the rule for another state. A complete calculation therefore separates the federal estate-tax layer from any state inheritance or estate-tax layer.
Who files and when
When a federal estate-tax return is required, the executor files Form 706. Internal Revenue Code section 6075 generally sets the due date at nine months after the date of death, and an extension of time to file may be available. The filing obligation belongs to the estate’s administration; it is distinct from an individual beneficiary’s income-tax reporting.
A beneficiary may instead encounter tax reporting when inherited property produces income, when income in respect of a decedent is received, or when inherited property is sold. Those events involve different forms, taxpayers, and measuring rules. Keeping the estate, the beneficiary, and the type of tax separate is the clearest way to understand how much inheritance tax may actually be involved.
