Families with estates above $13,990,000 just gained a permanent shield from the federal estate tax. Congress enacted a $15,000,000 per-person exemption starting in 2026, replacing years of temporary thresholds that forced repeated last-minute planning. The change, signed into law as Public Law 119-21, removes the sunset clause that had kept advisers and wealthy households guessing about how much they could pass on tax-free.
Why a permanent $15 million exemption changes estate planning now
Until this year, the elevated estate-tax exemption existed on borrowed time. The 2017 tax overhaul roughly doubled the exclusion but scheduled it to snap back to pre-2018 levels after 2025. That expiration date created a narrow window in which families rushed to lock in large lifetime gifts before the rules reverted. With H.R. 1 becoming Public Law 119-21, Congress eliminated the cliff. The statute now sets the basic exclusion amount at $15,000,000 and indexes it for inflation beginning after 2026.
The practical effect is immediate for high-net-worth families and their advisers. A married couple can now shelter up to $30 million from federal estate and gift taxes with no legislative expiration hanging over the strategy. That certainty reshapes the calculus around dynasty trusts, which skip multiple generations and rely on the generation-skipping transfer (GST) exemption being tied to the same $15 million figure. The Congressional Research Service noted in its analysis that P.L. 119-21 made the higher exemption permanent and increased it to $15 million in 2026, directly linking the estate, gift, and GST exemptions at that level.
Before permanence, many couples relied on portability elections, which let a surviving spouse claim a deceased partner’s unused exemption through a simple tax return filing. Portability is convenient but does not extend to the GST exemption. With the exemption now locked in at a higher baseline, estate planners have a stronger incentive to fund irrevocable dynasty trusts during life rather than depend on portability alone. Comparing pre- and post-2026 Form 709 filing patterns and estate-tax return volumes will show whether that shift materializes at scale.
Code language and IRS guidance confirm the $15 million threshold
The updated text of Section 2010 of the Internal Revenue Code now states that the basic exclusion amount is $15,000,000. This provision cements the unified estate and gift tax system at a level that had previously been supported only by temporary legislation.
Committee documents clarify how lawmakers intended the change to work. In its explanation of the estate and gift provisions, the House Ways and Means Committee described the measure as one that “permanently increases” the unified credit to an inflation-indexed $15 million and aligns the GST exemption with that same figure. The committee’s narrative, contained in its formal committee report, underscores that Congress did not simply extend the prior higher threshold but chose to remove the sunset entirely.
On the administrative side, the IRS has begun updating its estate-tax filing instructions and threshold tables to reflect the new number. For decedents dying in 2025, the filing requirement still tracks the pre-2026 exclusion, but returns for deaths in 2026 and later will use the $15 million basic exclusion amount as the starting point. Parallel updates are expected for gift-tax returns, ensuring that lifetime transfers and bequests are coordinated under the same unified cap.
Planning strategies under a stable exemption
With a permanent exemption, planners can focus less on racing to beat legislative deadlines and more on matching structures to family goals. For some, that will mean using only a portion of the $15 million exclusion during life, preserving flexibility in case asset values or family circumstances change. Others may still choose to fully fund irrevocable trusts early, particularly when they anticipate significant appreciation in closely held businesses or investment portfolios.
The GST component is especially important for families interested in multigenerational planning. Because the GST exemption now tracks the full $15 million per person, it becomes easier to design trusts that can benefit children, grandchildren, and more remote descendants without incurring additional transfer tax at each generational level. That, in turn, may influence how families balance outright inheritances against long-term trust arrangements.
Charitable planning also shifts in a world where fewer estates face federal tax. With the exemption so high, many households that once expected to owe estate tax will now pass assets tax-free, reducing the purely tax-driven incentive to make charitable bequests. Advisors anticipate that philanthropic strategies will increasingly be driven by legacy and governance considerations rather than by the marginal estate-tax rate alone.
What wealthy families should watch next
Although the exemption is now permanent in statute, political risk has not disappeared. Future Congresses retain the power to revisit transfer taxes, and the history of estate-tax legislation suggests that thresholds can move sharply when fiscal or political priorities change. Families with estates near or above the $15 million mark will likely continue to monitor legislative developments and may build flexibility into their plans through powers of appointment, trust decanting provisions, and carefully drafted trustee powers.
For now, however, the law offers a level of clarity that estate planners have not enjoyed in more than a decade. A clearly defined, inflation-adjusted $15 million exemption gives families a stable baseline for deciding how much to give away during life, how much to retain, and which mix of trusts, entities, and beneficiary designations best matches their long-term objectives.
