The federal estate and gift tax exemption has risen to $15 million per person for 2026, which means a married couple can pass roughly $30 million to their heirs without owing any federal estate or gift tax. The figure was set by the One Big Beautiful Bill Act, which also made the higher exemption permanent and indexed it to inflation going forward. For most families the practical message is reassuring: the threshold now sits so high that federal estate tax touches only a very small number of estates. The nuance lies in the planning required to capture the full couple’s amount.
How portability doubles the exemption to $30 million
The $15 million figure applies to each individual, not to each couple automatically. Reaching the roughly $30 million total depends on a rule called portability, which lets a surviving spouse add the unused portion of a deceased spouse’s exemption to their own. Without it, an estate that leaves everything to the survivor could waste the first spouse’s exemption entirely, exposing more of the eventual estate to tax when the second spouse dies.
Portability is not automatic. It requires the executor to make an election on a timely filed federal estate tax return after the first spouse’s death, even when no tax is owed and no return would otherwise be required. That single filing preserves the deceased spouse’s unused exemption for the survivor. Skipping it is one of the most common ways families forfeit millions in shelter they were legally entitled to claim, as the IRS explains in its estate tax guidance.
The election is made on the estate tax return itself, and the window to file it is generous but not open-ended, which is why it is a step an executor has to plan for rather than stumble onto years later. Because that return often exists for no reason other than to preserve the carryover, families whose estates sit well under the threshold routinely assume no filing is required and let the deadline slip by unnoticed. Once the first spouse’s unused exemption is forfeited that way, it cannot be reclaimed after the fact, and the survivor is left with only a single exemption to shelter the combined estate.

Why most families owe no federal estate tax at all
The headline number can obscure how few estates ever reach it. With an exemption of $15 million per person, the overwhelming majority of American families fall far below the threshold, and their estates pass to heirs with no federal estate tax due whatsoever. The tax has always applied to a narrow band of the wealthiest estates, and raising the exemption to this level narrows that band further.
For a household well under the limit, the estate tax return itself is generally unnecessary, and the estate passes under the normal rules of a will or trust. The federal estate tax is a concern for a small minority of families with substantial assets, according to the IRS’s estate tax overview. That reality is worth keeping in view amid headlines about multimillion-dollar shelters, because the planning that captures a $30 million exemption is relevant only to estates approaching that size.
The distinction matters for how ordinary families spend their planning energy. A household with a few hundred thousand dollars or even a few million in assets is not navigating estate tax exposure at all; its concerns are wills, beneficiary designations, and avoiding probate. The estate tax exemption becomes a live issue only near the top of the wealth scale, where the difference between claiming one exemption and claiming both can be worth many millions.
What permanence and the annual gift exclusion change
One of the most consequential features of the new law is not the dollar amount but its durability. The higher exemption had been scheduled to fall in the coming years, which had pushed many wealthy families to accelerate gifts before an expected drop. By making the $15 million figure permanent and indexing it to inflation, the One Big Beautiful Bill Act removes that deadline pressure and lets families plan on a stable threshold that rises over time rather than one set to expire. For households that had been accelerating gifts to get ahead of the scheduled rollback, the change takes away the reason for haste and lets the timing of a gift turn on family circumstances rather than a looming legal cutoff.
Alongside the lifetime exemption, the annual gift tax exclusion remains a separate and useful tool. For 2026 an individual can give up to $19,000 per recipient without touching the lifetime exemption or triggering any gift tax filing, and a couple can combine their exclusions to give more to each person. Used consistently across children and grandchildren, those annual gifts can move meaningful sums out of an estate over years without consuming any of the multimillion-dollar lifetime shelter.
The combination of a permanent, indexed exemption and a steady annual exclusion gives high-net-worth families a more predictable framework than they have had in years. The open task is procedural rather than legislative: preserving a deceased spouse’s exemption through a timely portability election, and using the annual exclusion deliberately rather than by accident. For the small share of estates large enough to owe federal tax, those two mechanics decide whether a family shields the full $30 million or leaves part of it on the table.
