Families with estates above $13.99 million gained significant new planning room when Public Law 119-21, signed on July 4, 2025, raised the federal estate and gift tax basic exclusion amount to $15,000,000 per person for calendar year 2026. That single legislative change, which amended Internal Revenue Code Section 2010(c)(3), represents a jump of roughly $1 million per individual and effectively doubles the threshold to $30 million for married couples who coordinate their exemptions. The increase will likely push a measurable share of estates below the taxable line, shrinking the already small pool of returns that owe federal estate tax.
How the $15 million threshold reshapes estate tax exposure
The IRS confirmed the new filing level in its estate tax table, listing 2026 at $15,000,000. That figure replaces the prior statutory base of $5,000,000, which had been adjusted for inflation under the 2017 Tax Cuts and Jobs Act and reached $13.99 million for 2025, according to a Congressional Research Service overview of the estate and gift tax system. The law substituted “$15,000,000” for “$5,000,000” in the codified text of 26 U.S.C. Section 2010, resetting the starting point for future inflation adjustments.
The practical effect is straightforward: an estate valued at or below $15,000,000 in 2026 will owe no federal estate tax and, in most cases, will not need to file a return solely for tax purposes. For married couples, portability rules allow a surviving spouse to claim the unused portion of a deceased spouse’s exemption, bringing the combined shield to as much as $30 million. The CRS has noted that the estate tax already applies to a very small share of decedents, and each upward revision in the exemption narrows that group further.
A reasonable expectation is that taxable estate filings reported in 2027 and beyond will drop by more than the gradual decline that annual inflation indexing produced between 2020 and 2025. The $1 million single-year increase enacted by P.L. 119-21 is larger than any recent inflation adjustment alone, which means estates that would have been marginally taxable under the old threshold will fall out of the filing population entirely. No official IRS or Treasury projection of the precise filing-count decline has been published, so the exact magnitude remains an open question.
Statutory text and IRS guidance confirm the 2026 change
The IRS stated on its estate and gift tax updates page that “OBBB amends Section 2010(c)(3) by increasing the basic exclusion amount to $15,000,000 for calendar year 2026.” That language ties the change directly to the One Big Beautiful Bill Act and clarifies that the higher exclusion applies beginning with decedents dying in 2026. The same notice explains that subsequent years will again be indexed for inflation off the new $15 million base, rather than the earlier $5 million figure.
The agency’s gift tax FAQ separately confirms the signing date of July 4, 2025, and notes that the lifetime gift tax exemption tracks the same $15,000,000 figure, meaning donors can transfer up to that amount during life or at death without triggering federal transfer tax. Gifts above the annual exclusion still require Form 709 reporting, but they count against the lifetime cap rather than generating immediate gift tax liability for most donors. Only when cumulative taxable gifts and bequests exceed $15 million will the transfer tax system begin to impose actual tax.
From a technical standpoint, the statutory amendment is concise: it revises the cross-referenced dollar amount in Section 2010(c)(3) while leaving the surrounding structure of the unified credit regime intact. The unified framework, which treats taxable gifts and taxable estates as parts of a single lifetime transfer ledger, continues to apply. What changes is simply the size of the ledger space available before tax is due. Because the IRS has already incorporated the higher exclusion into its published tables and explanatory materials, practitioners have clear guidance for planning transactions that will close in or after 2026.
Planning implications for high‑net‑worth families
For individuals whose net worth hovers just above the prior $13.99 million threshold, the higher exclusion opens room to simplify planning. Some may decide that aggressive discounting strategies, complex valuation freezes, or large irrevocable transfers are no longer necessary solely to avoid federal estate tax. Others may use the additional capacity to equalize inheritances, fund charitable bequests, or make larger lifetime gifts without breaching the taxable line.
Married couples, in particular, gain flexibility in how they structure ownership and beneficiary designations. With a combined potential shield of $30 million, many will be able to rely on straightforward approaches such as portability elections and basic credit shelter provisions rather than highly engineered trust arrangements. That said, state-level estate or inheritance taxes, which often have much lower thresholds, can still justify more detailed planning even when a couple’s federal exposure has disappeared.
The timing of gifts also remains important. Because the unified credit is shared between lifetime transfers and bequests at death, large gifts made in 2026 and later will reduce the exclusion remaining for the estate. Families considering substantial transfers may want to coordinate annual exclusion gifts, charitable strategies, and use of valuation discounts to stretch the benefit of the $15 million cap. Advisors will also watch for any future legislative proposals that might lower the exclusion, as has occurred in prior tax reform cycles.
Overall, the move to a $15,000,000 basic exclusion amount marks a significant, legislated reset of federal transfer tax exposure for wealthy households. By codifying the higher threshold and aligning IRS guidance across estate and gift tax materials, Public Law 119-21 gives taxpayers and practitioners a clearer, more generous baseline from which to design long-term wealth transfer strategies.
