Enter a non-negative estate value.
Fewer than 1 in 1,000 estates owe federal estate tax at these exemption levels — this only applies to very large estates. It doesn't include any state estate or inheritance tax, which some states levy at much lower exemption thresholds. This is a simplified estimate using the top 40% rate; consult an estate planning attorney for actual filing.

Frequently asked questions
Will my estate actually owe this tax?
Almost certainly not — the 2026 federal exemption is $15 million per person ($30 million per married couple with full portability), made permanent by the OBBBA in 2025. Fewer than 1 in 1,000 estates in the US exceed this threshold.
Does this include state estate tax?
No — this is federal estate tax only. Some states levy their own estate or inheritance tax with exemption thresholds far lower than the federal one (sometimes $1-2 million), so a state tax could apply even when no federal tax is owed.
