0.00%The federal estate tax exemption is $15,000,000 for 2026, unified with the lifetime gift tax exemption.

Edit inputs ↑Frequently asked questions
What is the federal estate tax exemption?
The federal estate tax exemption is $15 million per person for 2026 (OBBBA made the $15M base permanent starting 2026, indexed thereafter), $13.99 million for 2025, and $13.61 million for 2024. Estates below this amount owe no federal estate tax. Married couples can effectively double the exemption through portability — $30M combined in 2026.
What is the unlimited marital deduction?
You can leave an unlimited amount to a surviving spouse who is a U.S. citizen without triggering estate tax. This effectively defers estate tax until the surviving spouse passes away. Non-citizen spouses can receive assets through a Qualified Domestic Trust (QDOT).
How do prior gifts affect estate tax?
The estate tax and gift tax share a unified exemption. Any taxable gifts made during your lifetime (above the annual exclusion) reduce the estate tax exemption available at death. The tax is calculated on the combined total of your taxable estate plus prior taxable gifts.
Do states have their own estate tax?
Yes, some states impose their own estate or inheritance taxes with much lower exemption thresholds. States with estate taxes include Connecticut, Hawaii, Illinois, Maine, Maryland, Massachusetts, Minnesota, New York, Oregon, Rhode Island, Vermont, Washington, and DC. Exemptions range from $1 million to $7.1 million.
