Imagine transferring millions of dollars in real estate, stocks, and business interests to your children through irrevocable trusts, only to realize months later that the tax deadline you feared was never going to arrive after all.

That is the predicament facing a growing number of affluent American families who moved aggressively to transfer wealth before the end of 2025, when the federal estate tax exemption was scheduled to be slashed roughly in half.

The cut never came, and now some of those parents could find themselves stretched thin, locked out of assets they once controlled, or watching their children grow richer while their own financial cushion shrinks.

Wealthy families scrambled to gift assets before a tax deadline 

Under the 2017 Tax Cuts and Jobs Act, the federal estate and gift tax exemption climbed to $13.99 million per individual by 2025, allowing married couples to shelter nearly $28 million from taxation at death, according to the Congressional Research Service.

That generous threshold had an expiration date, and without congressional action, the exemption was set to revert to approximately $7 million per person on January 1, 2026, exposing far more estates to a 40% federal tax rate, according to Tax Foundation analysis.

Facing that looming cliff, estate planners urged clients to act fast, and many families funneled enormous sums into irrevocable trusts, spousal lifetime access trusts, and outright gifts to lock in the higher exemption before it disappeared.

Then came the One Big Beautiful Bill Act, signed into law on July 4, 2025, which not only preserved the elevated exemption but raised it further to $15 million per individual and $30 million for married couples, effective January 1, 2026, according to the IRS.

Divorce, rising trust taxes, and envy are fueling regret among gift-giving parents

The reasons wealthy parents want their money back vary, but advisors point to three recurring themes that keep surfacing in client conversations across the country. Divorce ranks among the most common triggers for gifting regret, Mark Parthemer, chief wealth strategist at Glenmede, told CNBC’s Inside Wealth. 

Many couples used spousal lifetime access trusts, commonly called SLATs, to move assets out of their taxable estate while retaining indirect access to those funds through their spouse, according to Fidelity Investments.

“While SLATs aren’t the right choice for everyone, they can be a powerful tool for some high-net-worth folks to use their federal estate and gift tax exemption early and efficiently, allowing assets to grow outside the taxable estate,” said Jordan Klein, an advanced planner at Fidelity.

When the marriage dissolves, the spouse who funded the trust loses that indirect lifeline entirely, creating a financial gap that no amount of legal maneuvering can easily close. Rising tax obligations present another burden that catches grantor trust creators off guard, Robert Westley, senior vice president and regional wealth advisor at Northern Trust, explained to CNBC.

Because grantor trusts require the creator of the trust to pay income taxes on dividends, capital gains, and other earnings generated by trust assets, parents can find themselves shouldering a growing tax bill on wealth they no longer control.

Wealthy parents might regret gifting assets as divorce, rising trust taxes, and lost financial control create unexpected long-term consequences.

Getting gifted assets back from a trust comes with serious IRS risks

Parents who feel overextended do have some legal avenues to pursue, but each one carries complications that can erode or even reverse the tax benefits the original gift was designed to achieve.

Robert Strauss, partner at Weinstock Manion described a case involving a married couple who transferred two California properties into a trust for their children, then decided to sell the Malibu home for at least $17 million and keep the proceeds.

The proposed solution involves splitting the trust, selling the property through one offshoot entity, and having that entity lend the cash back to the parents at a market-rate interest, which is legally permissible but far from risk-free.

If the IRS concludes that the parents are functioning as the real beneficiaries of the trust, the agency could reclassify those assets as part of the parents’ taxable estate, effectively wiping out the entire tax advantage of the original transfer.

An alternative to borrowing is swapping non-liquid assets held by the parents with income-producing assets held inside the trust, which is allowable when the two sides are of equal value, Westley of Northern Trust noted.

The $124 trillion wealth transfer means family conflicts over gifted assets will only grow

These disputes are unfolding against the backdrop of what researchers have called the largest intergenerational transfer of assets in history, with approximately $124 trillion expected to change hands through 2048, according to Cerulli Associates‘ 2024 U.S. High-Net-Worth and Ultra-High-Net-Worth Markets report.

Of that total, approximately $105 trillion is projected to flow directly to heirs, with baby boomers and older generations accounting for roughly 81% of all transfers, the research firm estimated in its 2024 U.S. High-Net-Worth Markets report.

For everyday families watching this play out, the lesson is both practical and cautionary: irrevocable transfers are permanent by design, and the tax code can shift in ways that no one can predict with full certainty.

Estate planners urge families to build flexibility into trust structures

The trust-protector approach offers one safeguard against gifting regret. Scott Rahn, a trust and estate litigator who advises parents to build flexibility into their estate plans, such as designating a trust protector who can modify the terms of the trust if the grantor falls ill, told CNBC’s Inside Wealth that he expects more disputes of this nature in the years ahead.

The new $15 million exemption under OBBBA may also reopen room for additional tax-free transfers among families who exhausted their lifetime exemption under the prior rules, according to estate planning analyses from firms including Pierce Atwood and Arnold & Porter.

Whether those additional transfers make sense depends on whether existing trust structures still align with a family’s broader objectives a question advisors say is best examined alongside legal and tax counsel rather than tackled in isolation.
