2027 Changes the Estate Planning Conversation in a Fundamental Way
For the better part of two decades, estate planning for wealthy families was conducted under a cloud of uncertainty. The federal estate and gift tax exemption was scheduled to sunset, then extended, then scheduled to sunset again, and every planning decision was filtered through the question of whether the window would close before the strategy could be executed. That era ended with the One Big Beautiful Bill Act, which made the increased exemption permanent and indexed it for inflation. For 2027, the IRS has announced that the lifetime estate and gift tax exemption will be $15.48 million per individual, or $30.96 million for married couples, while the annual gift tax exclusion rises to $20,000 per recipient. Those figures are not dramatically different from 2026, but the certainty behind them is. The planning environment has shifted from a sprint against a deadline to a long-distance discipline, and the families who adapt to that shift will be the ones who transfer wealth most efficiently across generations.
The removal of the sunset pressure does not mean the stakes have diminished. It means the planning has become more deliberate, more structural, and more focused on the interactions between different parts of the tax code rather than on a single exemption number. Keith Fenstad, director of wealth planning at Tanglewood Total Wealth Management, described the change bluntly: the “use it or lose it” environment is gone, and advisors now have “more breathing room to plan deliberately and make decisions in the right sequence rather than rushing to act before a sunset date.” That sequencing matters enormously. A gift made in the wrong order, or a trust funded at the wrong moment in a business’s life cycle, can waste exemption capacity that could have been deployed more efficiently. The families who treat multi generational wealth planning as a one-time event will miss the opportunities that emerge from a more patient, coordinated approach.
The other structural change that deserves attention is the permanence of the generation-skipping transfer tax exemption at the same $15.48 million level. Unlike the estate and gift exemption, the GST exemption is not portable between spouses, which means a surviving spouse cannot inherit the deceased spouse’s unused GST capacity. For families planning to fund dynasty trusts that will benefit grandchildren and great-grandchildren, that distinction is critical. The GST exemption must be allocated deliberately during life or at death, and a failure to do so can result in a future tax liability that erodes the trust’s value at exactly the moment it is supposed to be transferring wealth to the next generation. The estate tax planning that works in this environment treats the GST exemption as a finite resource that must be deployed with the same care as the estate and gift exemption, not as an afterthought.
Dynasty Trusts and the Architecture of Multi-Generational Transfer
The dynasty trust has moved from a niche tool for the ultra-wealthy to the centerpiece of generational wealth preservation for families with estates approaching or exceeding the exemption threshold. The concept is straightforward: an irrevocable trust that is designed to last for multiple generations, often in a state that allows perpetual trusts, funded with assets that are expected to appreciate significantly over time. Because the assets are no longer owned by the grantor, they are removed from the grantor’s taxable estate, and the future appreciation escapes estate tax entirely. If the GST exemption is allocated to the trust, the assets can pass to grandchildren and great-grandchildren without triggering a generation-skipping transfer tax at each generational transition.
The power of this structure comes from the compounding of tax-free growth over decades. A family that funds a dynasty trust with $5 million today, and allocates GST exemption to it, is not simply removing $5 million from the estate. It is removing the future value of that $5 million, which at a 6 percent average return over thirty years would be roughly $28.7 million. The estate tax savings on that appreciation, at a 40 percent rate, would be more than $9 million. That is the arithmetic that makes dynasty trusts worth the legal complexity and the ongoing administrative costs. The families who use them effectively are not the ones who fund them with cash and forget about them. They are the ones who fund them with the assets that have the highest expected appreciation, and who coordinate the funding with the rest of their estate plan so that the exemption is used efficiently.
The funding decision is where most families leave value on the table. Closely held business interests, concentrated equity positions, and real estate held for the long term are the ideal candidates for a dynasty trust, because those are the assets with the greatest potential for appreciation and the greatest estate tax exposure if they remain in the grantor’s name. But funding a trust with those assets requires a valuation, and the valuation must be defensible. Minority interest discounts and lack-of-marketability discounts can reduce the reported value of the gifted interest, which means more assets can be transferred for the same amount of exemption. The IRS scrutinizes those discounts, and the families who succeed are the ones who have documented the valuation thoroughly and who have engaged qualified appraisers before the transfer, not after.
The timing of the transfer matters as much as the asset selection. Research on merger arbitrage has shown that the fair market value of a business interest rises incrementally as a sale or acquisition approaches closing, sometimes doubling between the pre-transaction value and the closing price. A transfer completed well before a liquidity event captures the lower valuation and shifts the post-transfer appreciation out of the estate. A transfer completed too close to the event risks triggering the assignment of income doctrine, under which the IRS may attribute the gain from the transaction to the donor rather than the trust. The wealth transfer strategies that work best are the ones that begin years before the expected liquidity event, not months.
The Tools That Freeze Value and Move Appreciation Out of the Estate
The dynasty trust is the destination, but the vehicles used to fund it determine how much value actually makes the transfer. The intentionally defective grantor trust, or IDGT, is one of the most flexible tools in this category. An IDGT is structured so that the grantor is treated as the owner for income tax purposes but not for estate tax purposes. That means the grantor pays the income tax on the trust’s earnings, which is effectively an additional tax-free gift to the trust, and the trust’s assets grow without the drag of income tax payments. The IDGT is often paired with an installment sale: the grantor sells appreciating assets to the trust in exchange for a promissory note at the applicable federal rate, which is typically low. The trust pays the note back with future cash flow, and the appreciation above the note’s interest rate accumulates in the trust, outside the estate.
The spousal lifetime access trust, or SLAT, is another tool that has become more attractive in the post-OBBBA environment. A SLAT is an irrevocable trust funded by one spouse for the benefit of the other spouse and descendants. The funding spouse uses their lifetime exemption to make the gift, removing the assets from their estate, but the beneficiary spouse can still access the funds if needed. That access provides a safety net that a pure dynasty trust does not, which makes SLATs more palatable for couples who are not certain they will never need the money. The risk is the reciprocal trust doctrine: if both spouses create SLATs for each other with substantially identical terms, the IRS may treat the trusts as reciprocal and include the assets in both estates. The drafting must be carefully differentiated, and the timing of the two trusts should not be simultaneous.
The grantor retained annuity trust, or GRAT, serves a different purpose. A GRAT allows the grantor to transfer assets into a trust while retaining the right to receive an annuity payment for a set term. If the assets in the trust outperform the IRS hurdle rate, the excess appreciation passes to the remainder beneficiaries at little or no gift tax cost. GRATs are particularly useful for volatile assets, because the grantor can set the annuity at a level that returns the entire contribution, resulting in a near-zero taxable gift, and the remainder beneficiaries capture whatever growth exceeds the hurdle rate. The limitation is that the grantor must survive the term for the transfer to be effective, which makes GRATs less suitable for older grantors or those in poor health. For younger business owners with concentrated stock positions, a series of rolling GRATs can move significant appreciation out of the estate without consuming exemption.
The common thread across all of these tools is that they require coordination. A GRAT that feeds its remainder into a dynasty trust, an IDGT that holds the business interests before a sale, a SLAT that provides spousal access while the dynasty trust holds the long-term assets: each piece solves a different problem, and the dynasty trust is the structure that ties them together. The families who use these tools in isolation capture a fraction of the benefit. The ones who integrate them into a coherent plan, with the GST exemption allocated properly and the valuations documented carefully, capture the full advantage of the permanent exemption.
The Basis Step-Up Trade-Off That Most Families Get Wrong
There is a counterweight to all of this gifting that gets far less attention than it deserves: the step-up in basis at death. When assets are held until death, the heirs receive a new cost basis equal to the fair market value at the date of death, which eliminates the capital gains tax on all the appreciation that occurred during the decedent’s lifetime. Assets held in an irrevocable trust do not receive that step-up, because the trust is a separate entity and the assets are not included in the grantor’s estate. For families whose estates are below the federal exemption threshold, the income tax cost of losing the step-up can exceed the estate tax savings from the gift. That is a trade-off that must be modeled, not assumed.
The calculus is particularly relevant for families in the middle of the wealth spectrum, roughly $5 million to $20 million, where the federal estate tax may not apply at all after the exemption is considered. A family with a $10 million estate that gifts $5 million into a dynasty trust to remove future appreciation from the estate may save nothing in federal estate tax, because the remaining $5 million is below the exemption anyway. But the $5 million in the trust will not receive a step-up at death, which means the heirs will owe capital gains tax on the appreciation when they eventually sell. If the appreciation is large, the capital gains tax could exceed the estate tax savings, especially if the heirs are in a high-income bracket.
The solution is not to avoid gifting entirely but to choose the assets carefully. Assets with a low basis relative to their current value, such as stock that has appreciated dramatically or real estate held for decades, are the ones where the step-up is most valuable. Holding those assets until death may be the better choice. Assets with a high basis, or assets that are expected to appreciate substantially in the future, are better candidates for gifting, because the step-up forgone is smaller relative to the future appreciation that is removed from the estate. The high net worth estate planning that produces results is the kind that models both the estate tax and the income tax consequences of each transfer, rather than focusing on the estate tax alone.
The grantor trust substitution power provides a mechanism for addressing this trade-off after the fact. Many irrevocable trusts include a provision allowing the grantor to swap assets of equivalent value into and out of the trust. If the grantor later determines that a particular asset should receive a step-up at death, they can substitute cash or high-basis assets for the low-basis asset in the trust, bringing the low-basis asset back into their estate. This power must be drafted into the trust from the beginning, and it must be exercised carefully to avoid inadvertently creating a taxable gift. But for families who are uncertain about the optimal allocation of assets between the estate and the trust, the substitution power provides a valuable option that can be exercised as circumstances change.
Annual Exclusion Gifts and the Discipline of Consistent Transfer
The annual gift tax exclusion is the simplest tool in the estate planning toolkit, and it is also the one that is most consistently underused. For 2027, the exclusion is $20,000 per recipient, or $40,000 for married couples who split their gifts. Those gifts do not consume any of the lifetime exemption, and they do not require the filing of a gift tax return as long as the total to each recipient stays within the limit. For a family with three children and five grandchildren, a married couple can transfer $320,000 per year without touching their $30.96 million lifetime exemption. Over a decade, that is more than $3 million moved out of the estate, along with all the future appreciation on those assets.
The discipline required to make annual exclusion gifts effective is not complicated, but it is easy to neglect. The gifts must actually be made each year, and the transfers must be documented. For families with younger beneficiaries, the gifts can be directed into 529 plans, which provide tax-free growth for education expenses, or into trusts with Crummey withdrawal powers that allow the annual exclusion to apply even though the funds remain in trust. The Crummey power gives the beneficiary a limited window to withdraw the contribution, typically thirty days, and if the beneficiary does not exercise that right, the funds remain in the trust for the beneficiary’s future benefit. That mechanism allows families to make annual exclusion gifts to a dynasty trust, building the multi-generational structure incrementally rather than requiring a single large funding event.
The 529-to-Roth rollover provision has added a new dimension to education-focused gifting. Under SECURE 2.0, up to $35,000 of unused 529 funds can be rolled into a Roth IRA for the beneficiary, subject to conditions including a fifteen-year account maintenance requirement and an annual rollover limit tied to the IRA contribution cap. The rollover is treated as a Roth contribution rather than a conversion, so it is not taxable income, and the income limits that normally restrict Roth contributions do not apply. For grandparents who superfund a 529 for a newborn grandchild, the provision transforms a single-purpose education vehicle into a multi-purpose wealth transfer instrument, with any excess funds eventually becoming a tax-free retirement account for the grandchild. The families who understand this provision can use 529 plans more aggressively, knowing that the downside of overfunding has been substantially reduced.
The annual exclusion is not glamorous, and it does not generate the same attention as dynasty trusts or GRATs. But it is the foundation on which the rest of the plan is built. A family that makes consistent annual exclusion gifts for twenty years, starting when the children are young, will have transferred a significant amount of wealth out of the estate, reduced the future estate tax exposure, and established a pattern of gifting that the next generation can continue. The family trusts and estate planning structures that work best are the ones that combine the sophisticated tools with the simple ones, and that recognize that the annual exclusion is not a minor provision but a core component of a multi-decade strategy.
Building a Plan That Survives Changes in the Law and the Family
The one certainty in estate planning is that the law will change. The exemption that is permanent today may be reduced by a future Congress, the GST rules may be tightened, and the valuation discounts that are available today may be restricted. The families who plan successfully are the ones who build flexibility into their structures rather than optimizing for the current rules at the expense of future adaptability. A trust that is drafted with a broad distribution standard and a flexible trustee can adapt to changes in the family’s circumstances and the tax law. A trust that is drafted with rigid, specific instructions may become a liability if the circumstances it was designed for no longer exist.
The family dimension is equally important, and it is the one that no tax code can address. Wealth transferred without preparation often disappears within a generation, not because of taxes but because the recipients were not equipped to manage it. The families who preserve wealth across generations are the ones who combine the legal and financial structures with education, communication, and a clear statement of the family’s values and intentions. Bringing the next generation into the planning conversation, explaining the purpose of the trusts, and establishing governance structures that allow the family to make decisions together are not soft additions to the estate plan. They are the mechanisms that determine whether the structures actually function as intended.
The multi generational wealth planning that succeeds in 2027 and beyond is not a collection of documents. It is an ongoing process that combines the permanent exemption, the dynasty trust architecture, the annual exclusion discipline, and the basis planning trade-off into a coherent whole, and that recognizes that the family dynamics are as important as the tax mechanics. The families who start early, coordinate their advisors, and revisit the plan as circumstances change are the ones who transfer wealth not just without paying unnecessary tax, but in a way that strengthens the family rather than fracturing it. The exemption is permanent, the tools are available, and the time to act is now, not when the next sunset appears on the horizon.
