Executive Summary:
With the One Big Beautiful Bill Act (OBBBA) increasing the federal estate tax exemption to $15M per individual in 2026, HNW families have more room to transfer wealth efficiently. But high-impact planning using tools like BDITs, PLIs, and dynasty trusts requires careful documentation, long-term oversight, and coordinated legal and financial implementation. State taxes, fiduciary risk, and compliance are still critical concerns. Planning today allows for strategic alignment rather than rushed execution.
The One Big Beautiful Bill Act (OBBBA) has permanently reshaped the estate tax landscape. Beginning in 2026, the federal estate tax exemption will increase to $15 million per individual—or $30 million per married couple—indexed for inflation moving forward. For ultra-high-net-worth families, this presents a significant opportunity to reassess existing planning structures, particularly as new exemption limits may alter how legacy wealth is protected, transferred, and taxed.
But while the long-term ceiling is rising, the work to prepare must begin now. Sophisticated estate planning often requires multi-phase implementation, and the tools used to optimize exemption utilization demand precision, documentation, and long-term compliance.
What Changes Under the OBBBA?
The OBBBA removes the sunset provision from the Tax Cuts and Jobs Act (TCJA), locking in an elevated exemption structure for the foreseeable future. By indexing the exemption, the law creates additional planning runway for families with substantial assets. However, this does not mean all planning should be deferred until 2026.
For many families, implementing foundational strategies today such as lifetime gifting, entity structuring, or insurance integration can provide a more strategic and defensible base from which to scale. Moreover, the exemption increase does not eliminate other risks such as state estate taxes, income tax exposure, or misaligned fiduciary arrangements.
Planning Opportunities Worth Considering
Structures like Beneficiary Defective Inheritor’s Trusts (BDITs), Private Loan Installment (PLI) arrangements, and dynasty trusts offer unique advantages for leveraging the full exemption. But they are not risk-free. These strategies often involve valuation discounts, intrafamily transactions, and retained access, which are factors that must be substantiated through proper documentation, appraisal, and third-party governance.
IRS scrutiny is not uncommon for structures that appear overly aggressive or insufficiently supported. Compliance starts with implementation: funding the trust, properly documenting business purposes, and maintaining arm’s length terms. Plans should not rely solely on the legal drafting but must be followed by deliberate execution and coordinated administration.
Implementation Is Not a Checkbox Exercise
High-impact estate plans don’t end with a signature. They require thoughtful asset allocation, retitling of accounts, clear operating agreements, and trustee oversight. This is especially critical for clients holding concentrated equity positions, illiquid business interests, or alternative assets.
As values increase and family dynamics evolve, plans must also be reviewed regularly for tax alignment, liquidity, and control. Trustees need guidance to fulfill fiduciary duties, particularly when making discretionary distributions or managing business assets across generations. Without ongoing attention to compliance, even well-structured trusts can fail to deliver intended results.
Coordination Across State Lines
While OBBBA addresses the federal estate tax, it does not change state-level estate tax regimes. Utah does not currently impose a state estate tax. However, many UHNW families also hold assets or reside part-time in states like New York, Oregon, or Massachusetts, where estate tax thresholds are significantly lower. Still, situs planning for trusts and careful selection of governing law remain critical when families have multistate exposure.
Estate plans must account for state-specific risks, not just federal thresholds. Failure to do so may result in avoidable tax liabilities and administrative friction.
Timing and Capacity: Be Strategic, Not Reactive
With a permanent exemption on the horizon, there may be a temptation to wait until 2026 to act. But thoughtful estate planning is not a last-minute exercise. Asset appraisals, coordinated gifting, and entity restructuring take time, especially when clients aim to transfer $30 million or more in assets.
That said, this is not a call for urgency-based planning. It’s a call for proactive alignment. Families who begin planning now will be better positioned to deploy exemption-driven strategies without rushing or compromising legal defensibility.
Choose advisors who not only understand structuring but can also support implementation, monitoring, and ongoing plan refinement.
Final Thoughts
The $30 million exemption era is not just about saving taxes. It’s about creating space to design multigenerational wealth strategies with greater control and fewer constraints. But bigger exemptions also bring greater scrutiny. The IRS has signaled an ongoing focus on aggressive valuation discounts, basis manipulation, and related-party transactions.
Effective planning will require more than creative structuring. It will demand durable compliance. That includes clean documentation, trustee education, state tax diligence, and coordination with financial and insurance teams.
If you’re evaluating how the new exemption structure could support your broader legacy and liquidity goals, now is the right time to explore those conversations—deliberately, not reactively.
