What Is the Federal Estate Tax Exemption for 2026?
Quick Answer: For 2026, the federal estate tax exemption is $15 million per individual or $30 million for married couples filing jointly.
The federal estate tax exemption represents the amount an individual can transfer at death without triggering federal estate tax liability. For the 2026 tax year, this exemption sits at a historically generous $15 million per person. This means fewer than one in 1,000 estates will face the federal estate tax. Married couples can effectively shield $30 million through proper planning.
As tax professionals advising high-net-worth clients, you should understand that this exemption is part of a unified system. The federal gift and estate taxes share the same lifetime exemption. Therefore, substantial lifetime gifts reduce the amount available at death.
Understanding Portability for Married Couples
Portability allows a surviving spouse to use any unused exemption from their deceased spouse. This effectively doubles the exemption to $30 million for married couples in 2026. However, portability requires filing Form 706 (United States Estate Tax Return) within nine months of the first spouse’s death. Missing this deadline costs clients millions in potential tax savings.
Tax professionals should implement systematic procedures to ensure timely portability elections. This is particularly important for clients whose estates may not immediately appear to need estate tax planning but could grow substantially over time.
Federal Estate Tax Rates
Estates exceeding the $15 million exemption face a top federal estate tax rate of 40%. This applies to the taxable estate value above the exemption threshold. For ultra-high-net-worth clients with estates of $50 million or more, this represents a significant tax burden without proper tax strategy implementation.
Pro Tip: The federal exemption adjusts annually for inflation. Advise clients to review their estate plans annually to ensure strategies remain optimized for current exemption levels.
