## What Is the Global Minimum Tax in Japan?
Japan has adopted reforms to meet international agreements under the OECD BEPS (Base Erosion and Profit Shifting) framework. The global minimum tax (第二の柱) ensures that multinational enterprise (MNE) groups pay a minimum effective tax rate of **15 %** in each jurisdiction where they operate.

## Key Changes That Affect Foreign-Controlled Entities (FCEs)
- **Foreign Subsidiary Aggregation (“GloBE rules”)**: Japan revised its foreign-subsidiary (外国子会社) taxation regimes. Updates include clearer rules on **paper-company exceptions**, changes to asset‐ratio tests, and using **highest statutory rates** where tax rates abroad are progressive and being misused.

- **Effective Date**: These changes apply to foreign-related corporations’ tax years beginning **April 1, 2026** or afterwards. If your entity is fiscal year ending March 2027, these rules apply.

## What Entities Need to Do (with Examples)
- **Example 1 – Japanese parent with foreign subsidiary in a low-tax jurisdiction**: If your foreign subsidiary has low local tax, Japan’s rules may impose a top-up tax to ensure 15 % overall effective rate (the “minimum tax”), especially if the subsidiary’s activities are limited.
- **Example 2 – Foreign financial entity used in global group structure**: The “paper company exception” may no longer apply if asset ratio tests and substance requirements aren’t met. Entities with minimal physical presence must now watch documentation and substance carefully.
## Compliance Steps
- **Audit current foreign subsidiaries**: Gather data on foreign tax paid, profits, assets, management control, and functions vs. substance.
- **Review your tax rate status in foreign jurisdictions**: If statutory rates are progressive, Japan may require using the maximum bracket for GloBE calculation. Some jurisdictions may qualify for “exempted location” status under Japan’s law. ([mof.go.jp](https://www.mof.go.jp/tax_policy/tax_reform/outline/fy2026/08taikou_05.htm?utm_source=openai))
- **Update documentation and policies**: Transfer pricing, board meetings, decision‐making and financing arrangements should reflect real economic substance.
- **Tax return preparation**: 日本の親会社 must follow new calculations for global minimum tax and report all foreign income/investments. Likely revisions in return schedules and supporting disclosures.
## Actions & Risks
- **Extra tax liability**: Expect potential additional corporate tax if your group’s foreign operations are taxed below 15 % and don’t meet exception criteria.
- **Reputation and auditing risk**: Japanese tax authorities will scrutinize structure, substance, and foreign entity arrangements.
- **Seeking guidance**: Given the technical complexity, working with tax advisors experienced in international corporate taxation is essential.
Japan has set a clear direction: align with global norms and clamp down on profit shifting. Entities must respond proactively.
