UN Wealth Tax Model Puts High-Net-Worth US Assets in Crosshairs

May 8, 2024

Private Client Services Partner, Thomas Giordano-Lascari, authored, "UN Wealth Tax Model Puts High-Net-Worth US Assets in Crosshairs" in Bloomberg Tax. Excerpts: The United Nations has offered a framework for countries that want to consider a wealth tax. For advisers of ultra-high net worth clientele in the US, a concern is the continued tendency of multilateral quasi-governmental bodies to push a “one ring to rule them all” uniform system of taxation with a net wealth tax being the latest policy du jour. That concern isn’t from a political point of view as to the merits of the policy objectives guiding the UN’s efforts, but rather from the perspective of a practitioner in the wealth planning space. Once a net wealth tax is ubiquitous in the domestic taxing legislation of a significant number of countries, the inevitable next step will be defining the reach of that tax, including extra-territorially.

Supreme Court Can Guide Congress in Foreign Earnings Tax Case

September 6, 2023

Private Client Services Partner, Thomas Giordano-Lascari, published the article, "Supreme Court Can Guide Congress in Foreign Earnings Tax Case" to Bloomberg Tax. Excerpts: In the tax world, the Supreme Court’s decision to hear arguments in Moore v. United States is a big deal because it challenges the constitutionality of a tax on foreign earnings known as a mandatory repatriation tax, or MRT, under Section 965 of the tax code. The plaintiffs argue that the MRT is a direct tax on property and must be apportioned. Specifically, they say the MRT isn’t a tax on “income,” as interpreted under the Sixteenth Amendment. The essence of this argument is that the plaintiffs, as shareholders of a controlled foreign corporation, haven’t “realized” any income but instead are being taxed on the value of their shares as measured by that corporation’s retained earnings—a direct tax on property.
