Doug McHoney (PwC’s International Tax Services Global Leader) is joined by Matt Ryan at PwC’s Global Tax Symposium in Rome. Matt is a Londonbased international tax partner and PwC UK’s Pillar Two Leader. Doug and Matt revisit the UK Pillar Two rules for the third time, but now from an enacted law perspective. While the rules are set to apply from the beginning of 2024, the United Kingdom faces an interesting challenge as one of the early adopters of Pillar Two, with enacted legislation, followed by additional OECD guidance. Doug and Matt discuss the tricky task for UK legislators of ‘painting while the paint still dries’ (i.e., enacting legislation while the OECD guidance is still changing) and some of the key differences that need to be addressed as a result of the subsequent OECD guidance, as well as stillexpected guidance in 2023 and beyond. Doug and Matt discuss from a practical perspective how UKparented taxpayers are preparing for what is ahead, including approaches to safe harbors. They then dive into complexities created by the particularities of the UK rules around the safe harbor and other key issues, like partnerships and deferred taxes. Finally, the podcast closes with practical next steps companies operating in the UK should consider ahead of 2024.
