Pillar One Modelling Tool

Software to Model Profit Reallocation under Pillar One

Our Pillar One Modelling Tool provides a calculation of the estimated profits reallocated to jurisdictions under Amount A of Pillar One and the estimated corporate income tax on those reallocated profits. 

Given Pillar One feeds directly into Pillar Two, it also estimates the Pillar Two top-up tax liability after the application of Pillar One.
