General Approach to Managing Pillar Two

The Pillar Two GloBE Rules will add a further burden on MNEs. However, if correct data extraction, cleansing and transformation systems are established the burden can be significantly reduced after the initial set up. Before all this is the tax data mapping assessment. This is the crux of an effective approach to implementing a system to manage Pillar Two.
 
MNE’s already have many different international tax reporting obligations aside from jurisdictional tax return submission, including CbC reporting (including EU public CbC reporting from June 2024), local and master files for transfer pricing and DAC 7 (from 2023).
 
Pillar Two includes an additional reporting obligation but in any well designed data management system data processes that are already in place (eg for CbC reporting) can be utilised for Pillar Two. 
 
Of course, the challenge with Pillar Two is that it essentially creates a separate, additional tax regime for MNEs.
 
Income for instance will be determined for financial reporting purposes, for tax purposes and also for Pillar Two purposes. Each is subject to separate rules. Therefore data extracted for Pillar Two purposes will be subject to a specific Pillar Two data transformation process that will then enable the calculation of the jurisdictional effective tax rate. 
 
The basic process for MNE’s will be:
