NIKKISO CO.,LTD. [6376.T]
TOKYO, Feb 10 (Pulse News Wire) – Nikkiso CO.,LTD. (6376.T) decided today to appeal to the Supreme Court over a tax dispute involving its subsidiary, Nikkiso International Co., Ltd.
The decision was made during a board meeting held on February 10 after receiving unfavorable rulings from lower courts. In August 2021, Nikkiso received a correction notice from the Tokyo National Taxation Bureau concerning its subsidiary group Clean Energy & Industrial Gas (CE&IG). In September 2022, the National Tax Tribunal rejected Nikkiso's review request. Following this, Nikkiso filed a lawsuit against the Tokyo District Court, which ruled against the company in May 2025. An appeal to the Tokyo High Court also resulted in a negative ruling in January 2026.
Despite these setbacks, Nikkiso remains unconvinced by the court decisions and plans to continue arguing the validity of its claims through the Supreme Court process. The company believes its arguments have merit and intends to pursue further legal action. Nikkiso had previously recorded approximately ¥1.700 billion in corporate income tax for the fiscal year ending December 2021, which has been fully paid. While the immediate impact on the current period’s performance is anticipated to be negligible, future developments could potentially affect future earnings. The company will promptly disclose any significant changes related to this case.
