Pillar Two establishes a global minimum tax regime which will apply to both public and privately held multinational groups with consolidated revenue over €750m. Global agreement has been reached to bring these rules into law and the OECD has released model rules, commentary and administrative guidance.
UK legislation has been enacted which introduces the OECD’s Pillar Two model Income Inclusion Rules into UK law. The rules first apply to accounting periods commencing on or after 31 December 2023. Whilst the UK has addressed some of the issues and complexities raised in respect of the OECD model rules a number still remain. These issues and complexities are being addressed through the OECD Implementation Framework workstream (“IF”) which is releasing further Administrative Guidance on an ongoing basis. This will then be incorporated into UK legislation in due course. Therefore, it is key to track the status of implementation for both reporting and compliance purposes.

Pillar Two Engine
Our Pillar Two Engine is a structured global model for calculating the impact of OECD Pillar Two. It simplifies modeling, analysis, and calculations, eliminating the need for manual updates for changing rules and legislation. It provides compliance and provision-grade calculations, as well as data visualisation to identify key jurisdictions where there is a risk of a Pillar Two tax requirement.
Complex, evolving regulations require dynamic, future-focused solutions.
A centralised, cloud-based calculation engine for quantifying the impact of Pillar Two, including provision, compliance, and modeling.
The Pillar Two Engine is adapted for relevant local rules and interpretations in order to meet Pillar Two requirements for global and statutory compliance, including constituent entity analysis, Transitional Safe Harbor assessments, and IIR, UTPR, and QDMTT computations and allocations.
