When Cornelius Vanderbilt died in 1877, his fortune was worth more than the United States Treasury’s cash reserves held at the time. His son doubled it within a decade. And in 1973, when 120 of his descendants gathered at Vanderbilt University for a family reunion, there purportedly wasn’t a single millionaire among them.
Perhaps surprisingly, the estate tax didn’t do that. The first Vanderbilt fortunes were largely spent, split, and scattered. The fortune died of mansions, yachts, dilution across generations, and the absence of any structure designed to outlive the people who built it. These days, the federal estate tax rarely destroys great fortunes on its own. However, unstructured inheritance does it faster, more reliably, and without a single form filed, and a lack of tax mitigation strategies can hasten the outcome.
That’s worth keeping in mind in 2026 because Congress created one of the largest federal transfer-tax exemptions in history, and a larger exemption can create a false sense that planning is no longer necessary. The families who treat this moment as a reason to relax will get one result. The families who treat it as an opportunity to build will get a very different one, and the gap between those two outcomes now compounds across generations. Let me explain.
The 2026 Numbers Rewrote the Question
As of January 1, 2026, an individual has a $15 million federal estate-and-gift tax basic exclusion amount before accounting for prior taxable gifts. With proper planning and, where applicable, portability, a married couple may be able to shelter up to $30 million. The generation-skipping transfer tax exemption also rises to $15 million, while the annual gift exclusion remains at $19,000 per recipient. The lifetime exemptions will adjust for inflation after 2026, and the annual exclusion continues to be indexed separately.1 More significant than the amounts is what’s missing. For the first time in two decades, there’s no sunset provision, no countdown clock, and no scheduled cliff forcing families to act by an arbitrary date.
Permanence, though, is a legislative word, and it means only that no expiration date is written into current law. A future Congress can lower these numbers with a simple majority and a signature. Anyone who watched the exemption double in 2018, nearly sunset in 2025, and then jump again in 2026 understands how quickly the ground can move. So the planning posture we recommend is straightforward. Use the current exemption deliberately, structure transfers so they’re completed rather than contemplated, and let the political weather do whatever it does.
There’s a second consequence of the higher exemption that gets less attention. With $30 million in headroom, the federal estate tax is no longer the binding constraint for most affluent families. The binding constraints become income tax, basis, trust design, and family governance. That shift changes which strategies earn their keep.

When the Estate Tax Recedes, Basis Takes Over
Assets included in a taxable estate receive a step-up in basis at death, which erases a lifetime of unrealized capital gains for the heirs. Assets given away during life carry the donor’s basis with them. For decades, planners accepted the lost step-up as the price of obtaining appreciation from a taxable estate. In 2026, with far fewer estates facing any federal estate tax at all, giving away low-basis assets can be an unforced error. The family avoids an estate tax it was never going to pay and voluntarily hands the next generation a capital gains bill.
The technical discipline is asset selection.
Cash, high-basis securities, and assets expected to appreciate steeply from today’s value are strong gifting candidates. Highly appreciated legacy positions, the founder’s stock, and the original real estate are often better held until death for the step-up. Grantor trusts add a powerful refinement here, because a retained swap power lets the grantor substitute high-basis assets into the trust and pull low-basis assets back into the estate late in life, positioning the right assets for the step-up without disturbing the trust’s economics.
Gift Now or Hold?
For a highly appreciated asset with a low tax basis, timing can change the basis inherited by the next owner.
The basis generally carries over.The gap remains with the recipient.
A step-up may close the gap.That can reduce embedded capital gain.
Takeaway: low-basis legacy assets are often worth evaluating before they are gifted.
A step-up depends on the law in effect, estate inclusion, ownership, and the asset's fair market value at death.
Some families can run the logic in reverse. Where an aging parent has unused exemption, upstream gifts of low-basis assets to that parent can produce a step-up at the parent’s death before the assets return down the family line. The one-year rule of Section 1014(e) denies the step-up if the parent dies within a year and the assets pass straight back to the original donor, so this only works with genuine planning runway and careful drafting.
Trust income tax adds the final wrinkle. In 2026, a non-grantor trust reaches the top 37% federal bracket when taxable income exceeds $16,000, while a single individual doesn’t reach that bracket until taxable income exceeds $640,600. The 3.8% net investment income tax can also apply to a trust’s undistributed net investment income once adjusted gross income exceeds the same $16,000 threshold.2 A trust that accumulates portfolio income year after year can therefore face a combined 40.8% federal marginal rate on affected income. Distribution policy, asset location inside the trust, and grantor versus non-grantor status are now income tax decisions with consequences that can compound over a generation.
The Trust Tax Runway
In 2026, the top 37% federal ordinary-income bracket begins above:
Takeaway: a non-grantor trust can reach the top income-tax bracket after retaining far less taxable income.
This compares bracket thresholds, not total tax owed.
Freeze What Grows, Keep What Steps Up
For families above or near the new exemption, the classic freeze techniques still do the heavy lifting, but the current rate environment changes their ranking.
A grantor retained annuity trust transfers future appreciation above a hurdle rate set by the IRS each month. That hurdle sits at 5.2% as of July 2026, which is demanding by the standards of the last fifteen years.3 A GRAT funded today generally creates a wealth transfer only if the assets outperform the Section 7520 rate over the trust term after accounting for the annuity structure and other planning assumptions. That argues for funding GRATs with concentrated, high-expected-growth positions rather than balanced portfolios, and for short, rolling two-to-three-year terms that capture bursts of appreciation while limiting the damage of flat years. Pre-IPO stock, a business unit ahead of a liquidity event, or a depressed asset with a specific recovery thesis are the natural candidates.
Clear the 5.2% Hurdle
Below the hurdle, the GRAT fails safely. The annuity returns the assets, and little is lost beyond setup costs. Growth that only matches the hurdle leaves nothing behind. The annuity reclaims everything. Growth above 5.2% stays in the trust for heirs after the annuity repays the grantor. Concentrated, high-growth assets are what make a GRAT work at today's rates.
Simplified zeroed-out three-year GRAT illustration using the July 2026 Section 7520 rate of 5.2%, level annuity payments, and constant growth, before costs. Not a projection. Actual results depend on the rate at funding, term, payment design, and asset performance.
An installment sale to an intentionally defective grantor trust can be an attractive alternative to a GRAT at today’s rates, particularly for families seeking multigenerational wealth transfer beyond the GRAT term. The note can be structured at the applicable federal rate, which may be lower than the Section 7520 rate. The grantor seeds the trust, typically with a gift of at least 10% of the purchase price, sells the appreciating asset to the trust for a note, and pays the trust’s income taxes personally, which serves as an additional tax-free transfer each year. For a family with substantial unused exemption, the higher 2026 amount can make it easier to capitalize the trust before a sale.
Entity structure can amplify both techniques. Interests in a well-managed family limited partnership or family LLC may support valuation discounts for lack of control and lack of marketability, allowing a given amount of exemption to transfer more underlying value when the structure has real economics and the valuation is properly supported. The discounts must be defended with respected formalities and a qualified appraisal, because this remains one of the most litigated corners of transfer tax law.
The GST Exemption
Most families use their gift exemption and ignore the generation-skipping exemption sitting beside it, which can undermine long-term compounding. Wealth left outright to children may face estate tax at a later generational handoff if it remains in a taxable estate. Wealth placed in a properly GST-exempt trust can avoid repeated transfer-tax exposure while the trust remains exempt and in force.
Here in Florida, that’s a long time. Trusts created on or after July 1, 2022 may last up to 1,000 years under the state’s amended rule against perpetuities, unless the trust terms require an earlier end.4 A Sarasota family that allocates its full $15 million GST exemption to a dynasty trust creates a vehicle designed to compound for grandchildren and great-grandchildren without estate or GST tax at each generational transfer, provided the trust remains properly structured and exempt. Run the arithmetic on $15 million growing at even modest real rates across three generations, and the numbers stop looking like estate planning and start looking like institution building. That’s the structural answer to the Vanderbilt problem, and the 2026 exemption provides unusually large capacity for families considering it.
SLATs Keep the Door Ajar
The hesitation we hear most often is understandable. Moving $15 or $30 million into irrevocable trusts feels like locking the vault and dropping the key. For married couples, the spousal lifetime access trust remains the most practical answer, because each spouse can benefit indirectly from the trust the other creates while the assets sit outside both estates.
We’ve covered the mechanics of SLATs before, and the design cautions haven’t changed. Two mirror-image trusts created at the same time with the same terms invite the reciprocal trust doctrine, which lets the IRS unwind the whole arrangement, so the trusts need genuinely different terms, trustees, timing, and beneficiary structures. And the plan has to survive divorce and an early death, both of which can sever the indirect access that made the structure comfortable in the first place.
Charity Got a New Rulebook in 2026
Families who give at scale should reprice their giving this year. Starting in 2026, itemized charitable deductions apply only to contributions above a floor of 0.5% of adjusted gross income, and taxpayers in the top bracket receive a deduction value capped at a 35% rate rather than 37%.5 Neither change is dramatic alone, but together they raise the after-tax cost of steady annual giving for high earners.
The structural response is concentration. Bunching several years of gifts into a single tax year clears the floor once instead of annually, and a donor-advised fund lets the family take the concentrated deduction while distributing to charities on its own schedule.
The choice between a donor-advised fund and a private foundation becomes a governance question as much as a tax one. Funding gifts with appreciated securities rather than cash still stacks a second benefit on top, since the embedded gain never gets recognized by anyone. And for families balancing income needs against legacy intent, charitable remainder trusts convert concentrated low-basis positions into diversified lifetime income with the remainder passing to charity, a structure that pairs well with the basis discipline described above.
Business Owners Have a New $15 Million Lever
One more 2026 change belongs in any serious generational wealth plan because it rewards structure put in place years before a sale. For qualified small business stock acquired after July 4, 2025, the gain exclusion cap rose to $15 million per issuer, the company-level gross asset ceiling rose to $75 million, and a new tiered schedule excludes 50% of gain after three years, 75% after four, and 100% after five.6
The estate planning connection is that the QSBS cap applies per taxpayer, and properly structured non-grantor trusts for children can each hold their own exclusion. A founding family that combines QSBS qualification with trust design well ahead of a transaction can multiply the exclusion across the family, which is exactly the kind of coordination that belongs inside a broader review of tax-efficient exit strategy.
In Conclusion
The 2026 rules removed the deadline, and that’s precisely the danger. Deadlines forced families to act. Without one, the work of using the exemption, allocating GST, managing basis, restructuring giving, and positioning business interests will feel optional right up until a future Congress, a death, or a liquidity event makes it urgent again.
These decisions inevitably intertwine. A gift that saves estate tax can create a capital gains problem, a trust that protects assets can generate a 40.8% income tax drag, and a charitable plan that ignores the new floor leaves deductions on the table, which is why we approach them as one system. If your estate plan predates the 2026 rules, it was written for a different tax code.
