Trump Administration Guts Corporate Minimum Tax via Treasury Rules

The Donald Trump administration is utilizing the United States Department of the Treasury and the Internal Revenue Service to grant hundreds of billions of dollars in tax breaks to multinational corporations, private equity firms, and cryptocurrency companies. These regulatory actions specifically target the Corporate Alternative Minimum Tax (CAMT), a provision of the 2022 Inflation Reduction Act designed to ensure large companies pay at least 15% on their book profits.

Recent measures include Notice 2025-27, which raised the safe harbor threshold for CAMT exemption from $500 million to $800 million. The Internal Revenue Service also granted exemptions for digital asset gains, benefiting firms such as Coinbase and Strategy, while private equity firms like Blackstone successfully lobbied for greater flexibility in calculating tax bills.

These changes follow the July 2025 signing of the $4 trillion One Big Beautiful Bill Act (OBBBA). While the OBBBA provides deductions for seniors, tips, and overtime pay, critics note it accompanies steep cuts to healthcare and food stamps. Democratic lawmakers and tax experts allege the administration is exceeding its legal authority to enact unlegislated tax cuts and create loopholes for the ultrawealthy. The Treasury Department defended the moves as a way to support American competitiveness by removing a compliance maze.
