## Key International Tax Reforms in FY2026
Two major areas affecting multinational entities (MNEs) in Japan:
1. **Global Minimum Tax (Pillar Two)**: Introduced to curb profit shifting and ensure a minimum 15% effective rate for large multinationals, aligning with OECD/G20 BEPS inclusive framework commitments.

2. **Foreign Subsidiary Consolidation (外国子会社合算税制)**: Adjusted scope and requirements for attributing foreign subsidiary incomes to Japanese parents, including rules for clean-up of certain defunct entities and redefining what qualifies as “investment volume” and treatment of permanent establishments.

## What Entity Setup or Restructuring to Consider
- **Corporate group threshold**: If your consolidated turnover is large, global minimum tax applies. Entities may need to restructure supply chains or shift profits to minimize exposure.
- **Foreign subsidiaries**: Review entity legal status (corporation vs partnership); check how foreign subsidiary income is being handled under the new consolidation regime. Certain entities may lose benefits if they previously escaped reporting under older thresholds.

- **Permanent Establishments (PEs)**: Determine whether overseas operations may be considered PE under Japan’s reformed foreign regime, especially after global minimum tax impact. PEs may lead to inclusion of foreign income and withholding requirements.
## Structuring Recommendations
- **Restructure inactive or small foreign entities**: Entities that were passive may incur consolidation or attribution. Simplification, sale, or converting them into non-stock entities may help.
- **Profit shifting tools need validation**: Intra-group loans, royalties, cost-sharing, etc., should be benchmarked; transfer pricing documentation strengthened.
- **Use of tax credits and incentives**: FY2026 reforms also expanded incentives for **large-scale/high-value capital investment** and special credit systems for productivity-linked investments. These can partially offset global minimum tax burdens. ([mof.go.jp](https://www.mof.go.jp/english/policy/tax_policy/tax_reform/08keyhighlight.pdf?utm_source=openai))
## Example Structuring Scenario
An overseas manufacturing group with a foreign affiliate (50% subsidiary) earning substantial profit from IP licensing. Under the new foreign subsidiary consolidation regime, these profits may now be attributed to the parent. A cost-sharing agreement may need review; alternatively, shifting licensing to Japan and managing royalties there might be more efficient, especially if Japanese income credits for R&D are available.
## Contacts & Next Steps
- Consult with transfer pricing and international tax experts to analyze your current foreign entities and projected global minimum tax exposure.
- Audit past and current tax returns for compliance and anticipate documentation needs.
- Evaluate capital investment plans to see if incentives in FY2026 law can mitigate incremental tax burdens.
- Where legal, consider restructuring ownership or evaluating location for high margin functions (e.g. IP holding, licensing).
These reforms mark a substantial shift in Japan’s international tax landscape. Proper planning and structure can yield efficient outcomes; ignorance could result in significant unexpected tax exposures.
