M&A and Pillar Two

The most ambitious tax reform in the last 100 years will impact M&A transactions

What is Pillar Two?


The OECD/G20 project to introduce a global minimum tax ("Pillar Two") is the most ambitious reform of international tax policy since the League of Nations introduced double tax treaties 100 years ago. It provides that multinational groups with consolidated revenues of at least € 750 million will be subject to a minimum tax rate of 15% per tax jurisdiction.

Why does it matter?


The OECD's GloBE Model Rules and accompanying documents are highly complex and require expert knowledge in tax law and international accounting standards such as IFRS, US GAAP and Swiss GAAP FER. Pillar Two Top-up Taxes differ in important aspects from traditional income taxes and therefore require a separate and differentiated approach in M&A transactions. Pillar Two will become an integral part of any M&A transaction and will play a crucial role in due diligence, transaction structuring, negotiations of the transaction documents and the subsequent integration of the target.

What are the key issues?

  • Pillar Two top-up taxes differ greatly from traditional income taxes. Differences include tax liability, group taxation, tax base, elections rights, and safe harbours.
  • Pillar Two necessitates broadening tax due diligence and understanding of the Pillar Two position of the Subject Group. Considerations include scoping of the tax due diligence scope, identification of tax risks in connection with Pillar Two, tax opportunities in relation to the subsequent integration of the Subject Group, tax information and tax base.

Consequences of non-compliance


In addition to the obligation to pay a top-up tax under Pillar Two, failure to comply with the filing requirements within 15 months after the fiscal year end of each constituent entity results in penalties.
