A draft opinion from the European Parliament proposes linking the EU’s 2028–2034 customs and taxation program to the implementation of the OECD/G20 BEPS framework. The report calls for program funding to prioritize coordinated enforcement of the inclusive framework rules, improved tax cooperation, and digital tools to combat cross-border tax fraud and inefficiencies in withholding taxes. Lawmakers also urged stronger transparency and oversight mechanisms to ensure the €6.2 billion program effectively supports EU tax policy objectives.

The Dutch state secretary of finance warned that major legal, administrative, and political obstacles could prevent implementation of a global minimum wealth tax on ultrawealthy individuals. In a letter to parliament, the official highlighted difficulties in obtaining reliable cross-border asset data and noted the absence of international consensus on economist Gabriel Zucman’s proposed 2% “top-up” wealth tax. The comments underscore growing skepticism within governments about the feasibility of coordinating a global wealth tax regime similar to the OECD’s BEPS project.

Herzfeld argues that international tax policy debates remain focused on the digital economy even as artificial intelligence is reshaping how businesses generate profits. The rise of AI challenges core tax concepts such as permanent establishment, nexus, and the transfer pricing framework built around DEMPE functions and human value creation. She suggests that massive investments by U.S. tech companies in AI infrastructure and the growing role of proprietary data may require policymakers to rethink how taxing rights and profits are allocated globally.

HM Revenue & Customs released a policy paper outlining reforms to the U.K.’s advance corporation tax (ACT) regime aimed at simplifying the treatment of surplus ACT balances. The measure will remove the “shadow ACT” rules that previously restricted companies’ ability to offset unrelieved ACT balances against corporation tax liabilities. Effective for accounting periods ending on or after April 1, 2026, the reform is expected to simplify corporate tax compliance and allow companies to utilize remaining ACT credits more efficiently.
