Preparing for the 2025 Corporate Minimum Tax and ESG Reporting Deadlines

The year 2025 marks a pivotal moment for finance leaders as two major compliance shifts take center stage: the OECD global minimum tax rules (Pillar Two) and impending ESG disclosure requirements. For CFOs, this isn’t just about ticking regulatory boxes—it’s about managing enterprise risk, maintaining investor confidence, and enabling long-term strategy in a shifting regulatory landscape.

As reported in multiple industry outlooks, including updates from PwC and the OECD, the minimum tax rules 2025 are already impacting multinational enterprises. At the same time, ESG expectations from investors, boards, and regulators are driving CFOs to lead environmental and social data governance with the same rigor as financial reporting.

Understanding the 2025 Corporate Tax Changes

The OECD’s Pillar Two introduces a 15% global minimum tax on large multinational enterprises (MNEs) with revenue over €750 million. Many countries, including the U.S., are implementing or aligning local laws to match.

For CFOs, this means:

• Identifying impacted entities across global operations

• Assessing exposure to the "top-up" tax

• Modeling financial impact across jurisdictions

• Coordinating closely with tax, legal, and FP&A teams

This shift requires a detailed compliance roadmap. CFOMeet.org offers events and whitepapers where senior finance executives share how they are preparing for the change and aligning global tax planning with financial forecasts.

Key requirements CFOs must prepare for:

• Reporting Scope 1, 2, and possibly Scope 3 greenhouse gas emissions

• Disclosure of material ESG risks and governance frameworks
