## Global Minimum Tax (GMT) & Pillar Two Basics
South Africa has adopted the **GMT legislation** as part of its anti-base erosion regime. All multinational enterprise (MNE) groups with consolidated revenue above **€750 million** (approx **R15 billion**) are affected. Rules include:
- **Income Inclusion Rule (IIR)**: Parent entities pay top-up tax if foreign subsidiaries are taxed below the 15% minimum effective rate.
- **Domestic Minimum Top-up Tax (DMTT)**: Ensures foreign-sourced income of foreign MNE groups taxed at minimum 15%.
Budget 2026 revised revenue projections from GMT down due to updated OECD analysis.([sars.gov.za](https://www.sars.gov.za/about/sars-tax-and-customs-system/budget/budget-2026-frequently-asked-questions/?utm_source=openai))
## Compliance & Disclosures
- You must submit the **Global Minimum Tax Return (GMT01)**, **Declaration (GMT02)** and full tax calculation each fiscal year.([sars.gov.za](https://www.sars.gov.za/businesses-and-employers/government/government-connect-issue-35-june-2026/?utm_source=openai))
- Deadlines: Return/payment due **15 months after the end of the fiscal year**, or **18 months** for first fiscal years between 1 Jan 2024-31 Dec 2024.([sars.gov.za](https://www.sars.gov.za/businesses-and-employers/government/government-connect-issue-35-june-2026/?utm_source=openai))
- Simplified Safe Harbour rules may apply for smaller or lower-risk entities. Examine whether Transitional CbCR or Simplified ETR Safe Harbour apply.([sars.gov.za](https://www.sars.gov.za/about/sars-tax-and-customs-system/budget/budget-2026-frequently-asked-questions/?utm_source=openai))
## Entity Setup Considerations
- When structuring new entities or group expansions abroad, assess whether foreign operations will trigger top-up tax. Consider jurisdictions with favorable tax rates or incentive schemes, but watch out for base erosion rules and substance requirements.
- Use **Special Economic Zone (SEZ)** regimes in South Africa, which may offer reduced rates (as low as 15%) under the right conditions—but reform of anti-avoidance rules is underway.([sars.gov.za](https://www.sars.gov.za/about/sars-tax-and-customs-system/budget/budget-2026-frequently-asked-questions/?utm_source=openai))
- Ensure robust documentation so that when audited, you can demonstrate your ETR calculations, tax payments, and that any DTA claims or exemptions are valid.
## Practical Tips & Example
- MNE with a subsidiary in an African country with a low corporate tax rate (say 10%) might now face top-up tax in SA under IIR. Plan whether to reallocate profits, adjust transfer pricing, or make use of treaties.
- A technology group earning R20 billion worldwide: verify whether Sars’ GMT regime applies, prepare disclosures ahead of deadlines, consider Safe Harbour to reduce paperwork.
## Key Take-aways
- Early planning is essential—don’t wait until year-end. Changing entity structure or location after the fact may not avoid PDT obligations.
- Consult tax professionals in all jurisdictions where operations exist—treaties, local rates, and administrative burdens vary.
- Keep updated with SARS guidance and updated external guides—they released several updated guides in June 2026 for GMT & tax-directive operation.([sars.gov.za](https://www.sars.gov.za/businesses-and-employers/government/government-connect-issue-35-june-2026/?utm_source=openai))"
