Why family offices and ultra-high-net-worth families are redefining what a successful estate plan looks like
There was a time when nearly every estate planning meeting for ultra-high-net-worth (UHNW) families started with the same question: “How do we reduce estate taxes?” The playbook was familiar. Transfer appreciating assets early. Use irrevocable trusts. Move future growth outside the taxable estate before it compounds beyond reach. For decades, that defined sophisticated estate planning. For many family offices, it still does.
Lately, though, the first question I hear is often different: “How much should we actually transfer?” That’s not a subtle shift; it’s a different conversation. Instead of asking how to move the greatest amount of wealth to the next generation, families are asking what they’re actually trying to accomplish by moving it. Increasingly, the goal is maximizing the odds that wealth benefits the people receiving it, not simply maximizing the amount transferred.
When the Math Stops Being Enough
Estate planners are trained to optimize measurable outcomes: taxes, discounts, projected appreciation, trust performance. Those numbers matter, and they model easily.
What doesn’t fit neatly into a spreadsheet is flexibility, whether the beneficiary who seems financially immature at age 25 is remarkably capable by 40, whether the operating business stays family-owned for another generation, or whether today’s irrevocable decision still makes sense in 20 years. Those questions rarely appear in an estate tax illustration. For family offices managing multigenerational, often concentrated wealth, they’re frequently the ones that matter most.
Two Tax Systems, Not One
The shift isn’t only emotional; it’s technical. For years, planning optimized one tax system, estate tax, while giving comparatively little attention to another: capital gains.
Assets transferred during life generally retain the donor’s cost basis; assets held until death generally receive a step-up in basis. For families with concentrated stock, long-held real estate, or closely held operating businesses — common across the family-office world — that distinction can materially change the economics of a transfer strategy. Sometimes lifetime gifting still wins; sometimes retaining assets produces a better result. Sophisticated planning now means weighing estate and capital gains taxes together, not treating one as an afterthought.
The Value We Rarely Price
From my perspective, the biggest shift hasn’t come from tax law; it’s come from watching families, including years spent helping build and operate a trust company.
One situation has stayed with me. A father transferred a meaningful stake in his company into an irrevocable trust for his two sons when the business was modest and the tax savings were significant. A decade later the company had grown well beyond projections, and one son wanted to borrow against the trust’s equity to expand. But the trust had no mechanism for the trustee to pledge shares, and amending it required consent from a co-trustee estranged from the family by then. The tax savings were real. So was the cost of having no flexibility when the family needed it most.
Decanting, judicial reformation, and trust modification are valuable tools, but they are not the same as preserving optionality from the start. Flexibility is an asset. Not one on the balance sheet, but one with real economic and human value, and for family offices and UHNW families holding concentrated, illiquid, or operating-business positions, that value compounds.
Weighing the Tradeoff
When a family asks how to balance transferring more now against preserving flexibility, I return to three questions:
- How concentrated is the asset, and how much basis is at stake? The larger the embedded gain, the more a future step-up can be worth protecting, and the more cautious I am about transferring that asset early.
- How likely is this family to need to touch the structure again? A family office with an active operating business, a blended family, or beneficiaries still finding their footing should weigh flexibility over efficiency more heavily than one with simpler, settled circumstances.
- What is the actual cost of waiting? Sometimes little is lost by transferring conservatively now and revisiting the decision in five years. Other times, a closing exemption or discount window makes waiting genuinely expensive. That cost must be priced specifically, not assumed.
What This Looks Like in Practice
A few decisions matter most in practice. Treat basis as a planning input, not a footnote, when deciding what to transfer and what to hold. Favor broad trustee discretion over rigid age-based distributions, which age poorly as beneficiaries’ lives unfold. Consider spousal access as a middle path between full transfer and full retention. Map each relevant state’s decanting and modification rules in advance. And treat the generation-skipping exemption as a deliberate decision, not a default, since it’s difficult to reallocate once used.
A Different Definition of Success
Early in my career, I measured a successful estate plan the way most advisors still do, tax saved, appreciation moved outside the estate, efficiency of transfer. Those questions still matter. I just don’t think they’re sufficient anymore.
The families I advise increasingly measure success differently. They still want tax efficiency, but they also want options, time, and confidence that the wealth they’ve built will strengthen the next generation, not simply support it.
That’s a different objective than maximizing wealth transferred, and it requires a different approach to planning. Financial capital has always been the traditional measure of a successful estate plan. The next generation of planning may be judged by something harder to quantify, whether it also preserves human capital.
