How the Estate Tax Calculator works
The calculation follows the standard method used across the US — no shortcuts, no hidden assumptions. Here is exactly what happens behind the scenes:
Formula
Taxable estate = gross − deductions − exemption → taxed up to 40%
Frequently Asked Questions
What is portability?
A surviving spouse can inherit the deceased spouse's unused exemption, effectively doubling shelter for married couples (~$28M in 2025) when Form 706 is filed.
Do states add their own estate tax?
About a dozen states levy separate estate or inheritance taxes with far lower thresholds (some as low as $1M). Check your state.
