Estate Tax Calculator

Federal estate tax. The exemption is large, is reduced by lifetime gifts already made, and can be doubled by porting an unused spousal exemption, which requires a return to be filed.

Also called: federal estate tax calculator, death tax calculator.

Nothing passing to a spouse in this calculation.

Computed from the published rates for the tax year you selected, which is not necessarily the current year. A calculation, not tax advice, and it does not know anything about your circumstances beyond the figures entered.

Method and background

This is what the calculation gives for the numbers you entered. It is an estimate, not advice, and it knows nothing about your situation beyond those numbers. Rules for United States change on a published schedule; the effective date is shown on every rule-based tool.

How this is calculated

The taxable estate is the gross estate less debts, administration expenses, charitable bequests and anything passing to a spouse, which is unlimited. The available exemption is the statutory amount less lifetime gift exemption already consumed, since the gift and estate exemptions are a single combined figure. Portability lets a surviving spouse add the deceased spouse's unused exemption, effectively doubling it, but it must be elected on a timely estate tax return even when no tax is due.

Method and limits

What it assumes

  • A federal calculation. Several states levy their own estate or inheritance tax with lower thresholds.

What it deliberately does not model

  • State estate taxes often start far below the federal exemption and are not included.
  • The exemption is scheduled to change, which affects planning materially.
  • Valuation of illiquid assets is the hard part of any real estate calculation.

Frequently asked questions

Does everything passing to my spouse escape tax?
The marital deduction is unlimited for a citizen spouse, so yes at the first death. It defers rather than eliminates: the assets are in the survivor's estate later.
Do I need to file if no tax is due?
To claim portability of an unused spousal exemption, yes. Missing that filing can cost the heirs the entire second exemption.
