The One Big Beautiful Bill Act, signed July 4, 2025, did something estate planners had been writing contingency memos against for three years. It made the federal estate and gift tax exemption permanent at $15 million per person, indexed for inflation, with no sunset. For ultra-high-net-worth families that locked in 2024 gifting to beat the anticipated December 31, 2025 cliff, the result is a structural over-allocation to irrevocable trusts that no longer serve their original tax purpose. For families with net worth between $3 million and $14 million, the entire planning question has flipped. The trust that was drafted in 2020 to dodge estate tax now sits idle on the estate-tax dimension and needs to be reread for what it was always also doing: managing income tax, protecting assets, and routing capital across generations. Stinson LLP’s Steven Redd, writing in the November 2025 issue of Trusts & Estates, framed the moment as the largest estate-planning reset since the 1986 Tax Reform Act. The Trust & Will 2026 Estate Planning Report measured the practitioner response and found that 64 percent of advised households in the $3M to $14M band intend to revisit their trust structures within 18 months.
The shift matters because the mid-tier estate is now the largest single segment of the trust services market. Cerulli Associates pegs the $3M–$14M household band at roughly 5.4 million U.S. families holding $32 trillion of investable assets, and the cohort had been operating under planning assumptions calibrated to the Tax Cuts and Jobs Act sunset that no longer applies. The Wiss CPA group’s November 2025 client memo captured the practical question advisors keep getting: if the estate tax is no longer the driver, why does the trust still exist?
Key Takeaways for Practitioners
- OBBBA permanently set the estate and gift tax exemption at $15 million per individual, $30 million per couple, with annual CPI indexing
- Families with $3M–$14M of net worth no longer have federal estate tax exposure but still benefit from trust structures for income tax, asset protection, and generational governance
- Roughly 64 percent of households in the band intend to restructure or close out existing trusts within 18 months according to the Trust & Will 2026 Estate Planning Report
- The intentionally defective grantor trust, dynasty trust, and domestic asset protection trust become the primary vehicles, with estate-tax-driven SLATs and GRATs receiving less attention
- 39 percent of RIA firms offer trust services in-house per WealthManagement.com’s 2026 RIA Outlook, up from 31 percent in 2024 as integration accelerates
What OBBBA Actually Changed
The TCJA had doubled the estate and gift tax exemption to roughly $11.7 million per person in 2018, indexed thereafter, with a hard sunset on December 31, 2025 that would have dropped the exemption to approximately $7 million per person inflation-adjusted. OBBBA struck the sunset, set the exemption at a clean $15 million per individual for 2026, and locked CPI indexing going forward. The generation-skipping transfer tax exemption was conformed to the same $15 million figure, and the gift tax annual exclusion rose to $19,000 per donee. The basic exclusion amount is now the foundation that every trust drafted between 2018 and 2025 was calibrated against, except the calibration was for a sunset that never arrived.
The dynamic the legislation interrupted is significant. Through 2024, ultra-HNW families and a meaningful slice of the mid-tier had funded SLATs, irrevocable life insurance trusts, and various forms of grantor retained annuity trusts on the operating assumption that the exemption would halve at year-end 2025. The IRS clarified through 2024 that gifts made under the higher exemption would not be clawed back, which created a strong fiscal incentive to gift aggressively before the cliff. Some families pushed $5M to $10M into trust structures, splitting between SLATs and dynasty trusts, expecting to capture the differential. With the cliff removed, those vehicles still hold the assets, but the original tax arbitrage disappeared.
KDA’s tax practice in their November 2025 white paper estimated that roughly $2.3 trillion of family wealth was moved into accelerated trust structures between January 2023 and June 2025, with the majority of that flow concentrated in the eighteen months before OBBBA’s passage. The unwinding question is not whether to dissolve the trusts but how to repurpose them for the planning dimensions that survive: income tax, asset protection, and multi-generational governance.
The Income Tax Repositioning
The intentionally defective grantor trust framework is the workhorse of the post-OBBBA mid-tier playbook. An IDGT is structured so that the grantor remains liable for income tax on trust earnings, which functions as a tax-free gift to the trust each year and depletes the grantor’s taxable estate at no transfer-tax cost. Under the old TCJA framework with a $7M anticipated sunset, the IDGT was a complement to estate tax planning. Under the OBBBA framework with a permanent $15M exemption, the IDGT becomes the primary structure for families that want to compress the grantor’s income tax base while moving asset growth out of the future estate, regardless of the estate tax math.
The mechanics are unchanged but the audience expanded. A surgeon married couple with $8M of net worth, sitting comfortably under the $30M joint exemption, had been told for years that an IDGT was overkill. Under OBBBA the same couple now hears the same trust pitched on income tax grounds: by routing investment portfolio assets through a grantor trust, the couple absorbs the tax burden during high-earning years and gradually shifts beneficial ownership to the next generation at no transfer cost. The math improves further if the assets thrown into the trust are growth-tilted rather than income-tilted, since the appreciation accrues outside the grantor’s estate.
Domestic asset protection trusts in South Dakota, Nevada, and Delaware also see renewed attention. These vehicles were always uncomfortable estate-tax fits because the self-settled feature reads as incomplete for federal estate inclusion purposes. With estate tax off the table for the mid-tier, the asset protection benefit stands cleanly on its own merits. The October 2025 Oppenheimer wealth note observed that South Dakota DAPT filings rose 27 percent year-over-year in the third quarter, the largest single-quarter increase since the state legalized the structure.
The Asset Protection and Governance Dimension
The middle-tier estate has always been more exposed to litigation, divorce, and second-generation creditor risk than its estate-tax bill suggested. OBBBA did not change that reality, and the practitioners who serve $3M-$14M families are now leading with asset protection language that used to sit deep in the trust marketing deck. A medical practice owner with $6M of net worth and ongoing malpractice exposure does not care that the estate tax exemption is $15M. The owner cares that a sufficient slice of household assets sits outside the practice entity and outside the marital estate in a structure that a future plaintiff cannot reach.
Family LLCs and limited partnerships return to the playbook for the same reason. The valuation discounts available on minority and lack-of-marketability interests survived OBBBA, and the structures continue to serve as both income-tax pass-throughs and governance vehicles. The discount work is less aggressive than it was during the pre-sunset rush, where practitioners pushed discount magnitudes that occasionally drew IRS examination. Under the new framework, a 25 percent combined discount on a family LLC interest gifted to an IDGT is unremarkable, and the IRS appraisal litigation pipeline has thinned.
Generational governance is the third leg. The Trust & Will 2026 report noted that 71 percent of trust restructuring conversations now include a written family governance document, up from 38 percent two years earlier. The instrument typically includes a successor trustee plan, an investment policy statement at the trust level, a distribution philosophy memorandum, and an annual family meeting calendar. The hard-dollar value of governance is harder to quantify than the tax math, but Cerulli’s mid-tier wealth survey found that families with documented governance reported 23 percent lower beneficiary disputes through 18-month observation windows.
What the Restructuring Actually Looks Like
The conversation with a $6M household sitting on a 2024-funded SLAT typically opens with three options. Option one is to leave the SLAT in place and treat it as a long-dated income-tax management vehicle, accepting that the estate tax rationale has evaporated. Option two is to decant the SLAT into a more flexible state-law trust structure, often a directed trust in South Dakota or Tennessee, that allows the beneficiary spouse broader access and substitutes asset protection as the primary planning thesis. Option three is to terminate the SLAT under the doctrine of mistake or material change in circumstances, distribute the assets back to the grantor, and start over with a different structure that fits the new tax frame.
The decanting path is the most common. The Trust & Will report measured 47 percent of restructuring engagements moving to decanting, 31 percent leaving structures in place with a re-papered purpose statement, and 22 percent unwinding entirely. The legal cost of a decanting runs in the range of $15,000 to $40,000 for a moderately complex trust, well below the cost of a full termination and refund, and the income-tax consequences are typically modest if the original grantor remains in place.
Plan sponsors and family offices are pushing trustees to provide a written planning memorandum that articulates the trust’s purpose under the new OBBBA frame. Vanguard’s family office practice updated its standard trustee communication template in October 2025 to require the memorandum, and the template is reportedly circulating among regional independent trust companies that previously did not require it.
Questions Advisors Should Bring to the Restructuring Conversation
Three questions cut through most of the noise. First, what was the original tax thesis of the trust as drafted, and does it survive OBBBA on its face? If the trust memorandum says “to avoid the anticipated TCJA sunset,” the restructuring case is straightforward. If the memorandum is silent or refers to multiple objectives, the conversation gets more nuanced and the family’s current income-tax bracket, litigation exposure, and intergenerational plan all need to be put on the table.
Second, what does the trust hold and what is the projected income tax burden over the next ten years? Trusts holding growth-tilted equity portfolios with low current yield benefit most from the IDGT grantor mechanic. Trusts holding income-heavy assets or operating business interests need to be repaper-ed against the cap on trust ordinary income at $15,650 of 2026 taxable income, which lands the trust in the top federal bracket faster than most clients realize.
Third, who is the next-generation trustee and does the governance document support the transition? A trust that worked beautifully under a 65-year-old grantor with active oversight often fails when the trustee role passes to a 35-year-old beneficiary with no fiduciary training. The OBBBA reset is a forcing function to confront the trustee succession question that practitioners had been deferring for years.
The mid-tier estate-planning market is going through its largest single repositioning since at least the 2012 estate tax compromise, and probably since 1986. The advisors who lead with income tax, asset protection, and governance language are taking share from those still pitching trusts on estate-tax grounds. The conversation worth having with every $3M-$14M household before year-end 2026 is whether the trust drafted in the old frame is doing the right work in the new one, and what the cost is to repaper it if it is not.
