For several years, affluent families, business owners, and their advisors prepared for a federal estate-tax cliff expected to take effect on January 1, 2026.
The expanded exemption created under the 2017 Tax Cuts and Jobs Act was scheduled to expire after 2025. Without new legislation, the amount an individual could transfer free of federal estate and gift tax was expected to fall by roughly half.
That possibility created urgency.
Families accelerated gifts. Attorneys drafted irrevocable trusts. Business owners explored valuation discounts and succession structures. Advisors modeled how much future appreciation could be removed from taxable estates before the window closed.
Then the cliff disappeared.
Legislation signed on July 4, 2025, amended the federal tax code and established a $15 million basic exclusion amount for 2026. The Internal Revenue Service confirms that the 2026 exemption increased from $13.99 million in 2025 rather than reverting to the much lower amount families had been expecting. (IRS)
For a married couple able to use both exclusions effectively, this may provide as much as $30 million in combined federal estate-and-gift-tax shelter before considering future inflation adjustments, prior taxable gifts, or a deceased spouse’s unused exclusion.
The sunset never happened.
But the disappearance of the deadline did not eliminate the transfer problem. It may have made the most dangerous part of it easier to ignore.
A higher exemption can reduce the urgency of a tax calculation while increasing the danger of an unfinished ownership transition.

This is Part 2 of Alliance Intelligence’s 10-part series on The Great Rotation: the movement of wealth, control and investment authority from the generation that accumulated it to the spouses, heirs, trusts, charities and institutions that will decide what it should accomplish next.
The first installment examined the transfer of ownership alongside a changing global buyer base for long-duration assets.
This installment examines a different risk.
What happens when a favorable change in tax law convinces families that they have more time than they really do?
Tax deadlines are visible.
They appear on calendars. Attorneys send reminders. Accountants build planning schedules around them. Families understand that a date certain can produce a measurable cost.
Mortality, incapacity, and family transition operate differently. They rarely arrive on a convenient planning schedule.
A founder can become incapacitated before a succession agreement is completed. One spouse can die before account ownership and beneficiary designations have been reviewed. A business can face a liquidity event while its ownership remains concentrated in an estate. A family disagreement can surface before anyone has clarified who possesses authority.
The expected 2026 estate-tax sunset created a sense that families had to act before a specific federal deadline. When Congress removed that deadline, many families gained valuable flexibility. They also lost the forcing function that had moved estate planning to the top of the agenda.
That is the central danger of the new regime.
A family may now conclude:
“Our estate is below $30 million. We do not have an estate-planning problem.”
What it may actually mean is:
“We may not currently have a federal estate-tax problem.”
Those are not the same statement.
The federal basic exclusion amount determines how much an individual can generally transfer during life and at death before federal estate or gift tax becomes payable.
It does not determine whether the transfer will work.
A $15 million exemption does not answer:
Who can operate the business after the founder’s death.
Whether a surviving spouse can access the right accounts.
How estate expenses will be funded.
Whether assets must be sold to create liquidity.
Whether children are prepared to become owners.
Whether one heir should receive operating control while others receive economic value.
Whether the estate is exposed to state-level taxes.
Whether creditor, divorce or litigation risks have been addressed.
Whether a trust can administer illiquid private investments.
Whether family members understand the purpose of the structures being created.
Whether the portfolio can survive a changing cost of capital.
The exemption is one number inside a much larger ownership architecture. It tells a family how much wealth may be transferred under current federal rules. It does not tell the family how that wealth should be governed, funded, protected or invested.
The federal exemption receives most of the attention because the number is large and the potential tax rate can be significant. But a family’s exposure cannot be evaluated from the federal exemption alone.
Depending on the family, relevant issues may include:
State estate or inheritance taxes.
Income taxes embedded in appreciated assets.
The basis treatment of assets transferred during life versus at death.
Generation-skipping transfer-tax considerations.
Life-insurance ownership.
Retirement-account beneficiary rules.
Entity-level restrictions.
Buy-sell agreements.
Partnership transfer provisions.
Real estate held across multiple jurisdictions.
Prior taxable gifts.
Portability between spouses.
Liquidity required to pay taxes, debts and expenses.
A household can fall below the federal taxable-estate threshold and still leave behind a deeply complicated transfer. A family can also succeed in reducing estate tax while increasing income-tax exposure, administrative complexity or loss of control.
The point is not that advanced planning is always required. It is that no single exemption amount can determine what planning is appropriate.
Married couples often hear that they can combine two federal exemptions.
That statement is directionally useful but operationally incomplete.
When one spouse dies, the executor may elect to transfer the deceased spouse’s unused exclusion to the surviving spouse. This is known as the deceased spousal unused exclusion, or DSUE amount.
The IRS states that a timely and complete Form 706 estate-tax return is generally required to elect portability, including for estates that otherwise would not have been required to file solely because of their size. (IRS)
That means a family can have an estate well below the federal filing threshold and still need to make a deliberate filing decision to preserve the deceased spouse’s unused exclusion.
This detail matters because the surviving spouse’s balance sheet may change dramatically after the first death.
The surviving spouse may:
Live for another 20 or 30 years.
Receive life-insurance proceeds.
Inherit additional assets.
Sell a business.
Experience substantial appreciation.
Remarry.
Make significant lifetime gifts.
Become the sole owner of concentrated real estate or securities.
A family that assumes the combined exemption exists automatically may discover later that an important election was never made.
Portability can be a valuable tool.
It is not a substitute for planning, and it does not solve every generation-skipping, state-tax, asset-protection or governance problem.
The current federal law establishes the $15 million exclusion for 2026 and provides for inflation adjustments in later years. (IRS)
That is materially more favorable than the reversion families had anticipated.
But “current law” should never be confused with “permanent economic reality.”
Future Congresses can amend tax rules.
Asset values can grow much faster than inflation.
A family that appears comfortably below the exemption today may not remain there.
Consider a household with a $16 million net worth divided between two spouses.
At first glance, a potential $30 million combined exemption may make the federal estate tax appear irrelevant.
But suppose the balance sheet includes:
A privately owned business valued at $7 million.
Commercial real estate valued at $5 million.
Public securities worth $2 million.
Retirement accounts worth $1 million.
Life insurance and other assets worth $1 million.
If the operating company grows, the real estate appreciates and insurance proceeds become includable in the estate, the family’s eventual exposure may bear little resemblance to the current calculation.
The estate tax is assessed against the value that exists when transfers occur—not the value that existed when the family decided planning could wait.
The most consequential estate-planning asset is often not the largest asset today. It is the asset with the greatest future appreciation.
A founder may own a company currently valued at $5 million that could be worth $30 million after expansion or a strategic sale.
A family may hold land whose value changes after rezoning or development.
A private investment may be early in its growth cycle.
A concentrated equity position may appreciate significantly.
A cold storage wallet with a few Bitcoin on it may surprise you in 10 years.
Intellectual property may become commercially valuable long after it is created.
When those assets remain inside the owner’s taxable estate, their future appreciation may remain there as well.
Depending on the structure and professional advice received, transferring an appreciating asset earlier may move some future economics outside the transferor’s estate.
That does not mean every appreciating asset should be gifted immediately. The decision involves tradeoffs.
A lifetime transfer can affect:
The owner’s access to income.
Control over the asset.
Income-tax basis.
Capital-gains exposure.
Creditor protection.
Valuation.
Voting rights.
Cash-flow allocation.
The recipient’s ability to hold the asset.
The family’s flexibility if circumstances change.
Estate planning should never become a competition to transfer the largest possible amount as quickly as possible.
The objective is not to win a tax-planning race.
It is to place the right assets into the right ownership structures without compromising the security of the people making the transfer.
The changing interest-rate environment adds another layer.
As discussed in Part 1, the Great Wealth Transfer is occurring while the buyer base for long-duration assets is changing. Higher sovereign yields raise the discount rate applied across public markets, private businesses, real estate and credit.
That can reduce valuations.
For transfer-planning purposes, a lower defensible valuation may allow more of an asset to be transferred within the available exemption.
But a lower appraisal does not automatically make the underlying investment more attractive.
The asset may be worth less because:
Its debt has become more expensive.
Its cash flow is weakening.
Its refinancing assumptions are unrealistic.
Its expected buyer has disappeared.
Its capitalization rate has increased.
Its operating margins have declined.
It requires more capital than previously expected.
Its exit multiple was built around a lower-rate regime.
Families need to separate two questions.
Is this an efficient moment to transfer the asset?
And:
Is this still an asset the family should want to own?
An estate-planning opportunity cannot repair a weak capital structure. A trust can hold a distressed asset for decades just as easily as it can hold a productive one.
The legal wrapper does not improve the underlying economics.
THE $30 TRILLION RESET
The new federal exemption gives families more flexibility, but it does not decide who should own the business, how liquidity will be created, or which assets are capable of surviving the next capital regime.
