Families with estates between $14 million and $15 million will no longer owe federal estate tax after the basic exclusion amount jumped to $15,000,000 per person for deaths occurring in 2026. The increase, up from $13,990,000 in 2025, traces directly to the One, Big, Beautiful Bill, signed into law on July 4, 2025 as Public Law 119-21. The change rewrites the math for executors, estate planners, and surviving spouses across the country.
How the $15 million threshold reshapes estate-tax exposure
The practical effect is straightforward: any estate valued at or below $15,000,000 now passes to heirs free of federal estate tax. That is a $1,010,000 increase over the 2025 figure. For married couples who each use the full exclusion, the combined shield reaches $30,000,000. Estates that would have filed Form 706 and potentially owed tax under the prior ceiling may now fall entirely outside the filing requirement. The concentration of that relief sits squarely among estates valued between roughly $14 million and $15 million, the band that was taxable last year but is not in 2026.
The hypothesis that fewer estates will file Form 706 in 2026 follows logically from the higher floor. Every dollar of additional exclusion removes some estates from the taxable universe. No official IRS projection of 2026 filing volume or revenue loss by asset bracket has been published, so the precise magnitude of the drop cannot yet be quantified. Still, the direction is clear: a higher exclusion means fewer taxable estates, and the effect will be most visible among those just above the old line.
For families whose wealth hovers near the new threshold, the change also alters the marginal value of last‑minute planning moves. Techniques such as deathbed charitable bequests or final‑year gifting may now offer less federal tax benefit if the estate is already projected to fall below $15 million. Conversely, families just above the line may find that relatively modest lifetime transfers or valuation discounts are enough to eliminate federal estate tax exposure altogether.
Statute, IRS guidance, and congressional scoring behind the $15 million figure
The statutory text is explicit. The amended Section 2010 of the Internal Revenue Code now reads: “For purposes of this subsection, the basic exclusion amount is $15,000,000.” An amendments note in the code attributes the change to Pub. L. 119-21, Section 70106.
The IRS confirmed the number through multiple channels. Its estate and gift tax update page lists the 2026 basic exclusion amount at $15,000,000 in a year‑by‑year table, with 2025 shown at $13,990,000, and notes that the One, Big, Beautiful Bill amended Section 2010(c)(3). A separate inflation‑adjustment bulletin referencing Rev. Proc. 2025‑32 restates the same figure and clarifies that the new exclusion applies to decedents dying in calendar year 2026.
On Capitol Hill, the Joint Committee on Taxation’s general explanation of Public Law 119‑21, released as JCX‑36‑25, describes the higher exclusion as part of a broader package aimed at “simplifying wealth‑transfer taxation while maintaining progressivity.” The committee’s revenue tables project a multiyear decline in estate‑tax receipts, concentrated among estates in the upper‑middle of the wealth distribution rather than the very largest. Those projections, however, rest on economic and mortality assumptions that may diverge from actual filing experience once the new threshold is in place.
Open questions about state taxes, sunset risk, and planning timelines
Several gaps remain in the public record. No IRS or JCT dataset breaks down how many estates, state by state, will newly fall below the federal filing threshold. That leaves state revenue departments and budget offices to model the indirect effects on their own. In states that tie their estate or inheritance taxes to federal concepts, a higher federal exclusion could shrink the pool of returns that provide audit leads and valuation benchmarks, even if state‑level tax liabilities remain unchanged.
Another unresolved issue is political durability. Public Law 119‑21 does not include an explicit sunset for the $15 million basic exclusion amount, but future Congresses could revisit the figure, especially if estate‑tax receipts undershoot expectations. Estate planners are already warning clients that a long‑term strategy built around today’s threshold should include contingency plans, such as flexible trust structures and powers of appointment that can adapt if the exclusion is reduced.
Timing also matters for families considering lifetime transfers. Because the new exclusion applies based on the year of death, not the year of planning, individuals in fragile health during the transition from 2025 to 2026 face unusual uncertainty. Some may accelerate gifts to lock in use of the higher exclusion through portability, while others may wait to see whether additional technical guidance emerges.
For now, advisers are urging executors and high‑net‑worth families to monitor official channels closely. The IRS frequently posts clarifications and procedural updates on its public legal guidance portal, and further explanations of filing thresholds, portability elections, and interaction with gift‑tax rules could shape how the $15 million exclusion functions in practice. Until those details are fully fleshed out, the headline is simple: starting in 2026, far fewer moderately wealthy estates will face federal estate tax, but the long‑term contours of the system remain very much in flux.
