Japan tax newsletter 23 March 2023

The ruling parties (a coalition comprised of the Liberal Democratic Party and Komeito) released an outline of the 2023 tax reforms (hereinafter, “Outline”) on 16 December 2022. This newsletter provides an overview of the major amendments and revisions contained in the Outline.

The 2023 tax reform signals a clear commitment from the Japanese government to unleash and ignite the latent potential of individuals, businesses, and local regions of Japan via the intentions embedded in this year’s revisions to tax frameworks. In order to ensure this “virtuous cycle of growth and distribution” continues to flourish, a tax system which encourages investment in the growth of markets, industries, and people must be strengthened across the board, and wide-ranging income redistribution policies must be enacted both in and outside of the tax arena.

The NISA investment scheme will be drastically expanded in scope and duration in an effort to achieve the Double Asset-based Incomes Plan for citizens. New tax incentives will be created, and existing tax incentives will be revised in order to significantly elevate the startup ecosystem and promote the creation and development of new industries. Revisions to R&D incentives will also facilitate an increase in investment activities. Lastly, Pillar 2’s global minimum tax (“GMT”) agreed upon in the OECD/G20 Inclusive Framework on BEPS will come into effect on 1 April 2024.

Please note that the content of this newsletter may be partially revised, deleted, or supplemented in response to future Diet deliberations on the reform bill.
