Very few estates owe federal estate tax because the exemption is so high — $13.99M per person in 2025, effectively ~$28M for a married couple using portability. Above the exemption, the rate climbs to 40%. Many states also levy their own estate or inheritance tax with far lower thresholds.
How it’s calculated & sources
Taxable estate = total estate − the exemption for your status. Estimated tax applies the top 40% federal rate to the excess. This is a simplified view; trusts, gifts and state taxes change the real picture.
Source: IRS 2025 federal estate-tax exemption ($13.99M individual). Note: the exemption is scheduled to roughly halve in 2026 unless extended — a key planning window.

Worked example
A $5M estate for an individual is well under the $13.99M exemption, so no federal estate tax is due — though a state estate tax still could apply.
