Foreign investors have reportedly avoided approximately 99 billion yen (around $690 million) in Japanese taxes between 2020 and 2022 by routing investments through Singapore, leveraging a long-standing treaty loophole. According to sources familiar with Japanese tax authorities and investigative reporting by Nikkei, this strategy enables investors to benefit from dual corporate and dividend tax breaks.
The practice involves foreign investors channeling capital through tax havens such as the Cayman Islands to Singapore, where these funds are injected into a specific Japanese corporate vehicle called a tokutei mokuteki kaisha (TMK), or special-purpose company. The treaty between Japan and Singapore, which has remained largely unchanged for over 30 years, facilitates this tax efficiency by allowing profit distributions to tap into favorable tax treatment at multiple levels.
Background on the Treaty Loophole
The Japan-Singapore tax treaty was designed to avoid double taxation and prevent tax evasion between the two countries. However, the static nature of the treaty has inadvertently created an opportunity for investors to “double dip”—claiming tax exemptions or reductions both at the corporate and dividend distribution levels. This has led to significant revenue loss for Japan’s tax authorities amid rising scrutiny of cross-border tax planning strategies.
Implications for Policy and Enforcement
Japanese tax officials are reportedly intensifying their focus on these arrangements, with discussions underway to close the loophole through treaty renegotiations or enhanced domestic regulations. The issue highlights the broader challenges governments face in keeping international tax frameworks up-to-date in an era of increasingly complex global investment structures.
Singapore, recognized as a major financial hub with favorable tax policies, has long been utilized by multinational corporations and investors to optimize tax burdens. The use of TMKs in Japan adds another layer to this complex structure, providing tax efficiencies that are legal but increasingly viewed as aggressive tax planning.
Outlook
As international pressure mounts for greater transparency and fairness in cross-border taxation, both Japan and Singapore may seek to revise treaty provisions or introduce new rules that curtail such tax avoidance practices. Multinational businesses and investors should prepare for potential changes that could impact the attractiveness of Singapore as an intermediary jurisdiction for Japanese investments.
