A recent interpretation of the 'One Big Beautiful Bill' (OBBBA), as outlined in a tax law guide released by Congress' policy staff, has raised alarms among tax lawyers and financial advisors regarding a potential double taxation issue for trusts and estates [1]. According to the lawyers, a footnote in the Joint Committee on Taxation's Bluebook indicates that the deduction cap, previously thought to apply only to individuals, is also imposed on trusts and estates [1]. This means that even if a trust distributes all its income to beneficiaries, it may still be required to pay taxes on a portion of that income, resulting in what experts describe as double taxation [1].
The impact of this provision is not limited to ultra-wealthy trusts; trusts with as little as $16,000 in income could also face additional taxes, according to tax lawyers [1]. Dan Griffith, director of wealth strategy at Huntington Bank, emphasized that this issue could affect a $400,000 special-needs trust, not just $100 million dynasty trusts [1]. Griffith noted that trusts may be forced to sell assets to cover the tax liability, potentially sacrificing future investment returns, or reduce distributions to beneficiaries [1].
Justin Miller, national director of wealth planning at Evercore Wealth Management, described the provision as a 'mathematical nightmare' for tax professionals. He provided an example involving charitable giving, explaining that if trusts must pay income taxes, less money is available for charity, which in turn affects the deduction calculation [1]. Historically, trusts and estates could deduct income distributed to beneficiaries, ensuring income was only taxed once. The new limitation, however, disrupts this system [1].
The OBBBA's cap on itemized deductions means that top-bracket taxpayers now receive a deduction benefit of 35 cents per dollar, down from 37 cents, and this applies to charitable deductions as well [1]. Experts report that this change has already influenced the giving strategies of top earners [1]. While the Bluebook is an interpretation and not law, the financial advisory community is expressing significant concern about the provision's implications [1].
CONCLUSION
The interpretation of the OBBBA's deduction cap as applying to trusts and estates has sparked concern among tax professionals, who warn of potential double taxation and its impact on both wealthy and modest trusts. The provision could force trusts to sell assets or reduce beneficiary distributions, and is already affecting charitable giving strategies. Market participants and advisors are closely watching for further clarification or legislative action.
