South Africa’s corporate tax regime in 2025 sets forth a clear and structured set of obligations for resident companies and multinational groups. This overview details the essential features of South Africa’s corporate tax, including current rates, assessment basis, and recent implementation of global minimum tax standards impacting larger multinationals.
Corporate Tax Structure in South Africa
For the 2025 tax year, South Africa operates a flat-rate corporate income tax system. The main features of this system are highlighted below, based strictly on the most recently released official figures.
| Tax Component | Details (ZAR) | Percentage (%) |
|---|---|---|
| Main Corporate Income Tax Rate | – | 27% |
| Tax Type | Flat rate (no brackets) | |
| Assessment Basis | Corporate entities (standard companies) | |
Key Rate: 27%
South African resident companies are subject to a flat 27% corporate income tax on taxable income. The currency used for all taxation purposes is the South African rand (ZAR).
Recent Developments: Domestic Minimum Top-up Tax (DMTT) for Multinational Enterprises
Beginning from years of assessment commencing on or after 1 January 2024, South Africa has introduced a new Domestic Minimum Top-up Tax (DMTT) under the OECD’s Pillar Two framework. This measure specifically affects multinational enterprise (MNE) groups that meet certain thresholds.
| Surtax / Top-up | Rate (%) | Applicable Condition |
|---|---|---|
| Domestic Minimum Top-up Tax (DMTT) | 15% | Applies to MNE groups with global annual consolidated revenue of at least €750 million (approx. $812 million, using an exchange rate of €1 = $1.08). If the group’s effective tax rate in South Africa is below 15%, a top-up to 15% may apply. |
This top-up tax ensures large MNE groups operating in South Africa cannot lever low effective local rates to reduce their global tax burden below internationally agreed minimum levels. Only groups meeting the revenue threshold and with effective tax rates below 15% in South Africa are subject to this regime.
Corporate Tax Brackets and Holding Periods
South Africa’s corporate tax rate is applied at a flat rate of 27%. There are no progressive brackets for corporate income tax, and no differential rates based on holding periods for assets or shares. As no minimum or maximum holding periods are relevant to this assessment, this aspect does not impact corporate tax liability in 2025.

Pro Tips: Navigating Corporate Tax in South Africa
- Ensure your accounting systems are set up to distinguish income subject to the standard 27% tax from any potential top-up obligations under the DMTT, especially if you are part of a multinational group.
- Monitor global and South African legislative updates if your group’s total revenues approach or exceed €750 million, as DMTT implications may significantly alter your effective tax rate.
- Take advantage of the stable, flat-rate regime to simplify tax forecasting and budgeting for standard South African companies.
- Regularly review group structures and intra-group transactions if subject to international tax rules, as South African authorities adapt to global tax standards rapidly.
Official Sources for Corporate Tax Information
To sum up, South Africa in 2025 enforces a flat 27% corporate tax on local companies, alongside a 15% top-up (DMTT) for large multinational groups that fall below the agreed minimum effective rate. There are no progressive tax brackets or holding period taxes for corporates, making the regime relatively straightforward for domestic businesses, but requiring careful attention from international groups. Familiarity with these rates and recent changes remains essential for cross-border planning and effective tax compliance in South Africa.
