For years, families with substantial homes and savings faced a looming deadline: the federal estate-tax exemption was set to roughly halve at the end of 2025, potentially exposing more estates to a 40% tax. A tax law enacted in 2025 erased that cliff. Instead of falling, the exemption was locked in at $15 million per person for 2026, a threshold high enough that the vast majority of families owe no federal estate tax at all.
What the $15 million exemption changed
The One Big Beautiful Bill Act set a permanent federal estate and gift tax exemption of $15 million per individual, effective Jan 1, 2026, with the figure indexed for inflation in later years. For a married couple, the combined shelter reaches $30 million. The law replaced a scheduled sunset that would have pushed the exemption back down to roughly $7 million per person, a change that had driven years of contingency planning.
The federal estate tax applies only to the value of an estate above the exemption. An estate worth less than $15 million owes nothing at the federal level, and only the amount over that line is potentially taxed. Because the exemption now sits far above the value of a typical home and retirement portfolio, most households pass their assets to heirs without a federal estate-tax bill.

How a home passes down without a federal tax
The exemption covers the entire value of an estate, so a family home is included within it rather than taxed separately. A house worth several hundred thousand dollars, or even a few million, falls comfortably under the $15 million ceiling once combined with the owner’s other assets. As long as the total estate stays below the exemption, the home can pass to children or other heirs free of federal estate tax.
Heirs also generally receive inherited property with a “stepped-up” cost basis, meaning the value is reset to the fair market value at the date of death. That step-up can sharply reduce or eliminate capital-gains tax if the heirs later sell, a separate benefit from the estate-tax exemption but one that reinforces how lightly most inherited homes are taxed at the federal level.
Why the permanence matters for planning
The earlier law had a built-in expiration that created uncertainty for anyone trying to plan an estate. Advisers and families had to weigh whether to make large gifts before the higher exemption vanished, a race against a deadline that could have reshaped inheritances. Making the $15 million figure permanent, and indexing it to inflation, removes that ticking clock.
Permanence means families can structure wills, trusts and gifting strategies around a stable number rather than a temporary one. The inflation indexing also means the exemption will rise gradually over time, keeping pace with growing asset values instead of eroding. That stability is a meaningful shift for estate planning, which by nature spans decades.
The gift-tax side of the same exemption
The $15 million figure is a unified exemption that covers both estate transfers at death and large gifts made during life. According to the IRS estate and gift tax guidance, lifetime gifts above the annual exclusion count against the same lifetime total, so using the exemption to make gifts now reduces the amount available at death. The two are drawn from one shared pool.
That structure lets families with significant wealth move assets to the next generation during their lifetime while still sheltering the transfers, up to the combined limit. For most households, though, the annual gift exclusion alone covers ordinary giving, and the lifetime exemption is never touched.
The state taxes the federal exemption does not touch
The generous federal threshold does not override state law. A number of states impose their own estate or inheritance taxes, and several set their exemptions far below the federal $15 million, in some cases at $1 million or $2 million. An estate that owes nothing to the federal government can still face a tax bill from the state where the person lived or owned property.
The states that levy their own estate or inheritance taxes are a minority, but they include several with large retiree populations, and their exemption thresholds move independently of the federal figure. A handful also impose an inheritance tax, which is charged to the people who receive the assets rather than to the estate itself, with rates that can vary by how closely the heir is related to the deceased. Those rules mean a family’s exposure can hinge on where a person lives, where property is located, and who is set to inherit.
That distinction is easy to miss when the federal number is so high. Families in states with their own death taxes may still need planning even when the federal estate tax is not a concern. The safest reading of the new law is that it removes the federal estate tax as a worry for nearly everyone, while leaving state-level rules as the variable that determines whether an inheritance is truly tax-free.
