Who pays federal estate tax

The federal estate tax applies to the estate of a person who dies, before it passes to heirs. Since the One Big Beautiful Bill Act, the exemption is $15 million per person in 2026, indexed for inflation from 2027. Very few estates owe it, but those that do pay 40% on the amount above the exemption.

How the calculation works

  1. Start from the gross estate: real estate, investments, retirement accounts, business interests, life insurance you own and other assets at fair market value.
  2. Subtract debts, funeral and administration costs.
  3. Subtract amounts left to a U.S. citizen spouse (unlimited marital deduction) and to charity.
  4. Add taxable gifts made during life, beyond the annual exclusion of $19,000 per recipient.
  5. Tax = 40% × the amount above the exemption.

Worked example

Item Amount
Gross estate $20,000,000
Debts and expenses $500,000
Left to charity $1,000,000
Exemption $15,000,000
  1. Taxable estate: 20,000,000 − 500,000 − 1,000,000 = $18,500,000.
  2. Amount above the exemption: $3,500,000.
  3. Federal estate tax: 40% × 3,500,000 = $1,400,000.
  4. Effective rate on the gross estate: 7%.

Portability for married couples

When the first spouse dies, the executor can file an estate tax return to transfer the unused exemption to the surviving spouse. Combined with the marital deduction, a couple can pass up to $30 million free of federal estate tax. The election requires filing Form 706 even if no tax is due.

State estate and inheritance taxes

About a dozen states and the District of Columbia have their own estate tax, some with exemptions of $1 to $2 million, and a few states have an inheritance tax paid by heirs, with rates that depend on the relationship. Residents of those states can owe state tax even far below the federal exemption.

Planning tools

Annual exclusion gifts, gifts to charity, irrevocable trusts and life insurance held in a trust are common ways to reduce a taxable estate. These strategies have legal and tax consequences, so they are best set up with an estate planning attorney.

Income tax for heirs

Heirs usually receive a stepped-up basis: assets take their value at death, so gains built up during the owner’s life escape capital gains tax. Retirement accounts are the exception and are taxed as the heirs withdraw.

Frequently asked questions

What is the federal estate tax exemption in 2026?

$15 million per person, indexed for inflation from 2027. A married couple can shelter up to $30 million if the surviving spouse claims the late spouse's unused exemption (portability).

What is the federal estate tax rate?

The top rate is 40%, and in practice it applies to every dollar above the exemption, because the exemption is far above the point where the top bracket starts.

Is money left to a spouse taxed?

No. Transfers to a spouse who is a U.S. citizen qualify for the unlimited marital deduction, and bequests to qualified charities are deductible too.

Do states have estate or inheritance taxes?

Yes, about a dozen states and the District of Columbia levy an estate tax, often with much lower exemptions, and a few states levy an inheritance tax on heirs. This calculator covers the federal tax only.
