On 22 April 2026, the Constitutional Court delivered a landmark judgment in Absa Bank Ltd and Another v Commissioner for the South African Revenue Service [2026] ZACC 15. The judgment is the first Constitutional Court decision interpreting the General Anti-Avoidance Rules (“GAAR”) contained in sections 80A to 80L of the Income Tax Act, 1962.
The Court dismissed Absa’s appeal and confirmed SARS’ broad powers to challenge arrangements based on their commercial substance rather than their legal form. The decision is expected to have significant implications for structured finance transactions, preference share funding arrangements, cross-border financing structures, treasury operations and broader corporate tax planning.
Background to the Case
Between 2011 and 2015, Absa Bank Limited (“Absa”) and its subsidiary, United Towers (Pty) Ltd (“United Towers”), invested approximately R1.9 billion in preference shares issued by PSIC Finance 3 (RF) (Pty) Ltd (“PSIC3”).
The broader structure, which was introduced by entities associated with the Macquarie Group, involved a number of downstream entities and transactions, including:
- PSIC Finance 4 (RF) (Pty) Ltd (“PSIC4”);
- Delta 1 Finance Trust (“D1 Trust”);
- Macquarie Securities South Africa Limited (“MSSA”); and
- Brazilian government bond transactions and swap arrangements.
The structure generated returns that flowed back to Absa in the form of preference share dividends, which were exempt from income tax.
SARS contended that, in substance, the arrangement converted taxable interest income into tax-exempt dividend income and therefore constituted an “impermissible avoidance arrangement” under the GAAR provisions.
The Key Issues Before the Constitutional Court
The Constitutional Court considered several important questions relating to the interpretation of the GAAR provisions, including:
- Whether Absa was a “party” to the avoidance arrangement for purposes of section 80L;
- Whether the arrangement produced a “tax benefit” as contemplated in section 80A;
- Whether full knowledge of the entire structure was required before a taxpayer could be regarded as participating in an impermissible avoidance arrangement; and
- Whether the courts should focus on the legal form of the transactions or their commercial substance.
Absa’s Argument
Absa argued that:
- it did not have knowledge of all aspects of the downstream transactions;
- it merely participated in one component of a broader arrangement;
- it could therefore not be regarded as a “party” to the entire avoidance arrangement; and
- the dividends received were legally exempt dividends under the Income Tax Act.
In essence, Absa contended that SARS was seeking to attribute to it knowledge and participation in aspects of the structure of which it was allegedly unaware.
SARS’ Position
SARS argued that:
- the arrangement lacked genuine commercial substance;
- the overall purpose of the structure was to obtain a tax benefit;
- the structure effectively converted taxable interest into exempt dividend income;
- the relevant enquiry under GAAR is objective rather than subjective; and
- Absa materially participated in and benefited from the arrangement and was therefore a “party” to the impermissible avoidance arrangement.
The Constitutional Court’s Findings
The majority judgment, delivered by Majiedt J, found in favour of SARS and dismissed Absa’s appeal.
The Court adopted a purposive and commercially focused interpretation of the GAAR provisions.
The key findings of the Court included the following:
A taxpayer need not have full knowledge of every aspect of the arrangement:
The Court rejected Absa’s argument that a taxpayer can only be regarded as a “party” to an arrangement if it possesses full knowledge of every component of the overall structure.
The Court held that participation in, and material benefit from, the arrangement may be sufficient for purposes of section 80L, even where a taxpayer does not have visibility over every downstream transaction.
The GAAR enquiry requires consideration of commercial substance:
The Court confirmed that the GAAR provisions require courts to examine the commercial and economic substance of an arrangement rather than focusing exclusively on its legal form.
While the transactions formally generated exempt dividend returns, the Court accepted SARS’ argument that the broader structure was designed to achieve tax-efficient returns through highly structured financing arrangements.
The purpose enquiry under GAAR is predominantly objective:
The Court confirmed that the determination of whether an arrangement has a tax avoidance purpose involves an objective assessment based on the surrounding facts and circumstances.
Accordingly, a taxpayer’s assertion that it lacked full knowledge of every aspect of the arrangement will not necessarily prevent the application of GAAR.
The judgment confirms the potentially broad application of GAAR:
The judgment demonstrates the willingness of the courts to apply the GAAR provisions robustly in the context of sophisticated financing and structured transactions.
The decision is likely to strengthen SARS’ position in future disputes involving arrangements where the legal form differs materially from the underlying commercial outcome.
The Dissenting Judgment
Rogers J delivered a dissenting judgment.
The dissent expressed concern regarding the breadth of the majority’s interpretation of what constitutes a “party” to an arrangement and the extent to which participation in one component of a broader structure should expose a taxpayer to GAAR.
Although the dissent did not prevail, it highlights the continuing judicial debate regarding the appropriate limits of the GAAR provisions and may remain relevant in future disputes involving complex multi-party structures.
Why the Judgment Matters
The judgment significantly strengthens SARS’ anti-avoidance powers and is likely to influence the future design, implementation and governance of corporate financing structures.
Importantly, the decision reflects a broader judicial shift toward a substance- and commercially-driven approach to tax interpretation rather than a purely technical or formalistic analysis.
The judgment suggests that, even where transactions comply with the literal wording of the legislation, SARS and the courts may increasingly evaluate whether the overall commercial outcome and economic reality align with the legal form adopted.
The decision is particularly important because it:
- broadens the scope of who may be regarded as a “party” to an avoidance arrangement;
- confirms that courts will prioritise economic substance over legal form;
- weakens “lack of knowledge” defences in complex structures;
- expands SARS’ ability to challenge multi-entity financing arrangements; and
- reinforces the broad application of South Africa’s GAAR provisions.
The judgment is expected to have implications for:
- preference share funding structures;
- cross-border financing arrangements;
- treasury and structured finance transactions;
- banking and investment structures;
- BEE financing arrangements; and
- multinational tax planning.
GAAR and the Expanding Substance-Based Approach
The judgment may also have important implications for the future interaction between GAAR and other anti-avoidance or substance-based provisions, including transfer pricing.
Traditionally, transfer pricing rules focus on adjusting pricing outcomes to arm’s length standards. However, the reasoning adopted by the Constitutional Court potentially supports a broader substance-oriented approach in terms of which SARS may seek to challenge or recast the underlying structure itself where it considers the overall commercial rationale to be insufficient. SARS may increasingly attempt to use GAAR as a macro-substance override sitting above section 31. The judgment potentially strengthens SARS’ ability to move beyond traditional arm’s-length pricing adjustments toward broader structural recharacterisation arguments where the overall arrangement is perceived to lack sufficient economic substance or commercial coherence.
In this context, GAAR may increasingly operate not merely as a “last resort” anti-avoidance provision, but as a parallel interpretative framework through which SARS evaluates the commercial coherence and substance of complex arrangements.
This development could materially affect how taxpayers approach transaction structuring, particularly in relation to:
- cross-border financing structures;
- intra-group funding arrangements;
- hybrid instruments;
- treasury operations; and
- multi-entity investment structures.
The judgment suggests courts may now begin with a substance enquiry from inception, and not as has been done historically where taxpayers first analysed technical compliance, then specific anti-avoidance rules, and lastly GAAR. GAAR is no longer viewed merely as an exceptional anti-avoidance override applicable only after technical compliance has been established. Instead, the reasoning of the Court suggests that commercial substance may increasingly inform the primary interpretative analysis itself.
The judgment may also signal a practical shift in the burden facing taxpayers. Although the legal burden of proof remains governed by existing statutory principles, taxpayers may increasingly be required in practice to demonstrate that arrangements are supported by credible commercial objectives, economic substance and robust governance processes.
Accordingly, taxpayers may need to place greater emphasis on:
- contemporaneous commercial rationale documentation;
- board and governance records;
- demonstrable non-tax business purposes;
- operational substance; and
- alignment between legal form and commercial conduct.
More broadly, the judgment raises an important question as to whether reliance on black-letter technical compliance alone is becoming less certain in the context of highly structured arrangements.
Tax Risk as Enterprise Risk
The judgment also reinforces the increasingly strategic nature of tax risk management.
Tax disputes are increasingly extending beyond technical statutory interpretation into broader questions relating to commercial credibility, governance and enterprise risk.
In this environment, the sustainability of a structure may depend not only on whether the legal steps are technically valid, but also on whether the overall commercial narrative is coherent, commercially defensible and supported by objective evidence.
For many groups, this may require tax risk to be evaluated more holistically alongside legal, treasury, governance and reputational considerations. elevating the importance of formal Tax Risk Steering Committees within large corporate groups. Such committees may increasingly be required to assess tax structures not merely from a technical tax perspective, but in conjunction with treasury, governance, operational, reputational, and commercial considerations. Contemporaneous multidisciplinary review processes may become increasingly important in demonstrating that arrangements possess genuine commercial substance independent of tax outcomes.
Practical example
Assume the following structure:
- A South African operating company (“SA OpCo”) requires funding.
- Its U.S. parent establishes a Mauritius finance company (“Mauritius FinCo”).
- Mauritius FinCo has:
- minimal employees,
- outsourced administration,
- limited office presence,
- but holds legal title to intra-group loans.
- Mauritius FinCo borrows funds externally at 4%.
- Mauritius FinCo lends to SA OpCo at 9%.
- SA OpCo deducts the 9% interest in South Africa.
- Mauritius taxes the spread lightly.
- Transfer pricing documentation supports:
- the 9% rate as arm’s length,
- based on comparable uncontrolled loan pricing.
Historically, the dispute may largely have focused on:
- whether 9% was arm’s length;
- whether thin capitalisation thresholds were exceeded;
- whether section 31 pricing adjustments were justified.
Under a conventional section 31 analysis, SARS might argue:
- 9% should have been 7%;
- therefore 2% is excessive;
- and only the excessive portion is disallowed.
This is a pricing adjustment.
The structure itself remains intact.
Mauritius FinCo is still respected as the lender.
After the Constitutional Court’s reasoning SARS may contend that:
- Mauritius FinCo has insufficient economic substance;
- it performs no meaningful treasury functions;
- key funding decisions are actually made in the U.S. or South Africa;
- the entity assumes little real economic risk;
- the arrangement exists mainly to obtain:
- treaty benefits,
- interest deductions,
- and low-tax outcomes.
SARS could then argue that:
the overall commercial structure lacks sufficient commercial coherence and economic reality.
Instead of merely adjusting pricing, SARS may seek to:
- disregard Mauritius FinCo entirely;
- recharacterise the arrangement as:
- a direct U.S.-to-SA loan;
- OR an equity contribution;
- OR a conduit financing arrangement.
This becomes fundamentally different from a normal transfer pricing adjustment. The consequences may vary:
- SARS may deny the entire interest deduction rather than merely adjusting the rate.
- The treaty position may collapse if Mauritius is disregarded as beneficial owner.
- The funding may be recharacterised as disguised equity.
- SARS may impose understatement penalties based on impermissible avoidance findings.
- Treasury governance documentation may come under attack.
Historically the question was: “Was the pricing arm’s length?” The emerging question may increasingly become: “Should this structure exist in this form at all?” That is the structural recharacterisation risk that sophisticated taxpayers, treasury teams, and multinational groups now need to consider in the post-Absa environment.
Practical Considerations for Taxpayers
Following this judgment, taxpayers should carefully review existing and proposed financing and investment structures to assess:
- whether arrangements have sufficient commercial rationale independent of tax considerations;
- whether transaction steps could be viewed collectively as part of a broader avoidance arrangement;
- whether the legal form aligns with the underlying commercial substance; and
- whether adequate contemporaneous evidence exists supporting the commercial objectives of the structure.
The judgment also highlights the increasing willingness of SARS and the courts to scrutinise highly structured arrangements from a substance-over-form perspective.
The judgment suggests that future disputes may increasingly turn on whether the taxpayer can present a coherent and objectively credible commercial story explaining why the arrangement exists beyond the tax benefits obtained.
Conclusion
The Constitutional Court’s judgment in Absa v SARS represents one of the most significant South African tax judgments in recent years.
The decision materially expands the practical reach of the GAAR provisions and signals a continued judicial preference for substance over legal form in tax matters.
Taxpayers involved in complex financing or investment structures should carefully reassess the robustness of their arrangements in light of the Court’s expansive interpretation of the GAAR provisions.
