South Africa: Constitutional Court Clarifies Scope of GAAR in Landmark Absa Ruling. South Africa’s Constitutional Court has delivered a landmark judgment that significantly reshapes the interpretation and application of the country’s General Anti-Avoidance Rules (GAAR).
The ruling, delivered on 22 April 2026 in Absa Bank Ltd and Another v Commissioner for the South African Revenue Service, dismissed Absa’s appeal and affirmed the position of the South African Revenue Service (SARS).
Tax analysts note that this is the first time any court has provided judicial clarity on GAAR provisions under sections 80A to 80L of the Income Tax Act since their amendment in 2006.
Background: Structured Financing and Tax-Free Returns
According to the reported case details, Absa invested approximately ZAR 1.9 billion in preference shares issued by a special purpose vehicle.
The bank received dividends that were treated as tax-exempt.
However, it later emerged that the funds were routed through a series of entities and used in a complex financial arrangement designed to convert taxable interest into tax-free income.
This structure ultimately generated the dividends paid back to Absa.

SARS Applies GAAR to Re-Characterise Income
SARS challenged the arrangement under GAAR provisions.
The tax authority re-characterised the dividends received by Absa as taxable interest, arguing that the structure was designed primarily to obtain a tax benefit.
This formed the basis of the dispute that progressed to the Constitutional Court.
Court’s Majority Decision: Substance Over Form
In a majority decision, the Court ruled in favour of SARS and clarified two key principles that now shape GAAR application in South Africa.
1. Participation Does Not Require Full Knowledge
The Court held that a taxpayer can be considered part of an avoidance arrangement even without full knowledge of all its elements.
It was reported that the judges adopted an objective test, stating that if a taxpayer’s actions form part of the overall transaction chain, they may be deemed to have participated.
This interpretation prevents taxpayers from relying on ignorance as a defence.
2. Tax Benefit Must Reflect Economic Reality
The Court further held that the correct approach is to assess the transaction based on its economic substance rather than its legal form.
According to the judgment, once the artificial elements of the arrangement are removed, the returns received by Absa were economically equivalent to interest.
As such, they should be taxed accordingly.
Dissenting View Raises Concerns
In a dissenting opinion, one of the justices reportedly disagreed with the majority’s interpretation.
The dissent argued that a taxpayer should not be considered part of an arrangement they are unaware of.
It was also suggested that the actual tax benefit may have accrued to other entities within the structure, rather than Absa directly.
Observers note that this perspective highlights ongoing debates around the limits of GAAR application.
Implications for Taxpayers and Financial Institutions
Tax professionals say the judgment carries significant implications for corporate taxpayers, particularly financial institutions and multinational enterprises.
Key takeaways include:
- Ignorance is no longer a defence under GAAR where a taxpayer’s actions contribute to a structured arrangement
- Enhanced due diligence is critical, especially in complex financing and investment structures
- Substance-over-form analysis will be strictly applied by tax authorities
- Existing transactions may need to be reviewed for potential GAAR exposure
What This Means for Africa’s Tax Landscape
Although the ruling is specific to South Africa, experts say its implications extend across Africa, where tax authorities are increasingly adopting anti-avoidance frameworks.
The decision signals a broader shift toward:
- Stronger enforcement of anti-avoidance rules
- Increased scrutiny of cross-border and structured transactions
- Greater emphasis on transparency and economic substance
Conclusion
The Constitutional Court’s decision marks a defining moment in the evolution of anti-avoidance tax enforcement in South Africa.
While it provides long-awaited clarity on GAAR, it also raises the compliance bar for businesses operating in complex financial environments.
Tax advisors have indicated that companies should proactively reassess their structures to ensure alignment with both the letter and intent of tax laws.
