Japan enacts 2023 tax reform bill including legislation to implement IIR to align with OECD BEPS 2.0 Pillar Two
Japan’s 2023 tax reform bill (the Bill) was enacted almost immediately after passing the Japanese Diet on 28 March 2023. Recall that Japan’s 2023 tax reform outline (the Outline)1 was announced on 16 December 2022, and then submitted as draft legislation (the Legislation)2, 3 to the Japanese Diet4 on 3 February 2023. As the Outline noted, the Legislation contained laws to implement the IIR to align with OECD5 BEPS6 2.0 Pillar Two initiative. Generally reflecting the model rules (the Model Rules)7 established by the OECD, the law has been incorporated into the existing Japanese Corporate Income Tax Law. The amendments generally apply to fiscal years beginning on or after 1 April 2023, but the IIR will apply to fiscal years beginning on or after 1 April 2024.
The Legislation as it relates to the IIR provides:8
Legislation is being considered in Japan, to be included in tax reform for 2024 at the earliest, involving items that the OECD is expected to discuss in detail this year, such as the undertaxed profits rule (UTPR) and the qualified domestic minimum top-up tax (QDMTT).
