On November 15, 2023, the U.S. Tax Court held in YA Global Investments v. Commissioner that a non-U.S. private equity fund (YA Global) with a U.S. asset manager that bought equity and convertible debt of U.S. portfolio companies was engaged in the conduct of a trade or business within the United States for U.S. federal income tax purposes, all of its income was “effectively connected” to that trade or business, and the fund (which was treated as a partnership for U.S. federal income tax purposes) was liable for penalties and interest for failing to withhold with respect to its non-U.S. corporate feeder fund partner.
