Mistrust on Trusts
Trillions in Retirement Dollars Are Flowing Into Opaque Trusts - Justina Lee, Weihua Li and Denitsa Tsekova, Bloomberg Tax ($):
No one knows exactly how much money they control. No one can say how it’s all allocated. No single financial regulator is in charge of them. Yet Collective Investment Trusts are now a multi-trillion dollar business to rival mutual funds or ETFs — and are poised to become the backdoor through which more private assets are added to Americans’ retirement savings.
For years now, the country’s biggest employers have been slowly migrating workers’ nest eggs toward these pooled vehicles, which are used exclusively by retirement plans. For 401(k)s with more than 100 participants, about 40% of all assets were invested in CITs by 2024, according to Department of Labor data, up from 12% in 2010 and above the share allocated to mutual funds.
Senate Dems’ Bill Would Set New Tax on High-Value Trust Assets - Cady Stanton, Tax Notes ($):
The legislation would withhold 1 percent on trust assets between $50 million and $100 million; 1.5 percent on assets between $100 million and $250 million; 2 percent on assets between $250 million and $1 billion; and 3 percent on assets above $1 billion. The bill would also make the withholding against estate tax liability fully refundable to ensure it targets trusts that are avoiding payment on the existing estate tax.
Why it pays to keep an eye on Congress....
Wealthy families regret rushing to give gifts after tax law changed - Medora Lee, USA Today:
Many families in 2024 and 2025 rushed to their accountants, advisers and attorneys to set up estate plans to lock in the benefits of the soon-to-be expiring Tax Cuts and Jobs Act of 2017 (TCJA). TCJA lowered tax rates, doubled the standard deduction and doubled the lifetime gift exemption but was scheduled to sunset at the end of 2025. All that changed when President Donald Trump signed into law on July 4, 2025, his signature tax and spending package that made permanent all those provisions.

Mastercard Case Tees Up Wider Taxation of Credit Card Companies - Perry Cooper and Peyton Rhodes, Bloomberg Tax ($):

Court Adds Economic Substance Penalty in Microcaptive Follow-Up - Nathan J. Richman, Tax Notes ($):
The same circular flow of funds and flawed actuarial analysis that led the Tax Court to its earlier determination that the microcaptive structure at issue wasn’t insurance supported the IRS’s assertion that the deal lacked economic substance, Judge Christian N. Weiler wrote May 4 in a second memorandum decision in Kadau v. Commissioner.
A deep dive into how Justice Roberts sees Congress and taxes, in two of his biggest cases.
The Chief Justice and the Taxing Power - Alexander F. Peter, Tax Notes ($):
The power to tax is, in Roberts’s words, Congress’s “birth-right power.” Learning Resources Inc. v. Trump, No. 24-1287, at 15 (U.S. 2026). In two cases separated by almost 14 years, the chief justice has adjudicated a signature policy of the sitting president and looked to the taxing power as a key source of authority or lack thereof. Roberts’s jurisprudence on the taxing power suggests that he views it as special, even among core legislative powers. But the exact contours of the chief justice’s view of the taxing power are harder to ascertain.

EU Countries Give Blessing to Value-Added Tax Anti-Fraud Bill - Ryan Hogg, Bloomberg Tax ($):
The bill, agreed to at the Economic and Fiscal Affairs Council meeting in Brussels on Tuesday, would give the European Public Prosecutors Office and the European Anti-Fraud Office access to VAT information, rather than depending on bilateral exchanges of information. It’s expected to be finalized following a European Parliament vote in July.
Want a tariff exemption? One lobbyist lays out how to approach the Trump administration.
Getting Tariff Relief Involves an ‘America First’ Lobbying Pitch - Samir Kapadia, Vogel Group, Bloomberg Government:
Lobbying the Trump administration on tariff relief (a much more sophisticated term) is an art—not a science. You can’t just show up with a congressional letter of support in hand talking about job losses and severe economic harm. Those traditional arguments worked well in the past, but today, they’re not enough to strike a chord with the US Trade Representative, the Commerce Department, or the White House.
