Federal Estate Tax Calculator

Estimate taxable estate and federal estate tax using an entered exemption and rate.

Use current law, portability and complete deduction facts. Enter gross taxable estate estimate in dollars, debts and administration deductions in dollars, charitable and marital deductions in dollars, entered federal exemption in dollars and entered estate-tax rate in percent (40 means 40%). At the worked-example inputs, the simplified federal estate tax is $2,800,000. Only estates above the exemption owe federal estate tax, and only on the excess. On the example, an estate that is $7,000,000 above the entered exemption owes $2.8 million at 40%. Most estates fall far below the exemption and owe nothing, and the exemption is portable between spouses if the estate elects it. It returns simplified federal estate tax, taxable estate above exemption, estate remaining after modeled tax.

Entered estate-tax rate40.0%

How to interpret the result

Federal estate tax only applies above a substantial exemption threshold, so most estates owe nothing at all regardless of how large they feel to the family involved, and the tax that does apply is charged only on the value above that exemption, not on the estate's full worth.

Before you rely on it

What to check

Confirm the current exemption amount and whether portability from a deceased spouse applies before assuming any estate tax is owed at all.

The common error

Where people go wrong with federal estate tax calculator

Assuming a sizable estate automatically owes federal estate tax. The exemption threshold is high enough that the overwhelming majority of estates fall entirely below it and owe nothing.

Where the inputs come from

Gross taxable estate is the fair market value of everything the person owned or controlled at death, including real estate, investments, retirement accounts, business interests and life insurance the person owned. Debts and administration deductions include mortgages, funeral costs and legal fees. Charitable and marital deductions reduce the taxable estate. The federal exemption is set by law each year and is a personal amount; this tool takes an entered figure, so use the current published exemption, and the rate is 40% above it.

Using the simplified federal estate tax in a real decision

The larger practical issues for most families are state taxes, basis step-up and liquidity to pay bills.

When the result stops applying

The law has changed the exemption several times, and it is scheduled to adjust, so confirm the current amount for the year of death. Lifetime taxable gifts reduce the exemption available at death. Trusts, valuation discounts and special-use valuation change the taxable amount. This is a simplified estimate, not tax advice.

What to compare it with

See the state estate tax and inheritance tax calculators for state-level taxes, and the inherited IRA pages for income tax on inherited accounts. Estate planning with an attorney covers wills, trusts, beneficiary designations and gifting. The federal income tax page covers the decedent's final return.

Frequently asked questions

Who owes federal estate tax?

Only estates whose value exceeds the federal exemption, an amount set annually that covers the vast majority of estates. Everything above it is taxed at up to 40%.

What is estate tax portability?

A surviving spouse can use the deceased spouse's unused exemption if the estate files the right return, effectively doubling the exemption for a couple.

Do heirs pay income tax on inherited assets?

Generally not on the assets themselves, and they receive a stepped-up basis for most property, but withdrawals from inherited retirement accounts are taxable.
