A recent Supreme Court of Appeal (SCA) judgment has sharpened the risk for South Africans who hold money or assets offshore, especially where funds move back into South Africa without a clear paper trail.
The warning is not that offshore accounts are illegal. Many South Africans legitimately hold foreign investments, earn foreign income, or receive foreign transfers linked to inheritance, business activity, or global work arrangements. The problem arises when a taxpayer cannot credibly prove what an inbound foreign amount represents, and cannot support their explanation with reliable documents.
In the case that triggered renewed attention, SARS identified a foreign deposit of R1.67 million paid into a South African taxpayer’s account by an entity based in the British Virgin Islands. The taxpayer attempted to dispute SARS’s additional assessment and penalties, but the SCA ultimately upheld SARS’s approach after finding that the taxpayer’s explanations were inconsistent and not supported by credible evidence.
The broader message from the ruling is that SARS can tax an amount as income if the taxpayer cannot discharge the legal burden of proving that it is not taxable. It also signals that severe understatement penalties can follow where SARS concludes that the taxpayer’s conduct warrants it.
The case behind the warning
According to reporting on the judgment, SARS picked up the offshore payment during a lifestyle audit and asked the taxpayer to explain the source and nature of the funds.
The taxpayer first described the amount as a loan intended to cover legal fees and provided documentation to support that explanation. Later, the taxpayer changed their version, claiming the amount was a repayment of a shareholder loan linked to a dissolved foreign company, and then attempted to distance themselves from earlier documents that had been provided.
The SCA rejected the shifting explanations and upheld SARS’s assessment, reinforcing that the credibility of a taxpayer’s evidence can be decisive in tax disputes.
The court also upheld a 90% understatement penalty imposed by SARS and, according to legal commentary on the case, indicated that SARS could have imposed a higher penalty, with the 90% figure viewed as lenient in the circumstances.
Why this matters to anyone with money outside South Africa
South Africa uses a residence-based tax system. In general terms, South African tax residents are taxed on worldwide income, while non-residents are taxed mainly on South African-source income, subject to applicable rules and tax treaties.
This structure means foreign income and certain foreign receipts can be taxable in South Africa depending on a taxpayer’s residency status and the nature of the amount received. It also means SARS has a strong incentive to scrutinise unexplained inbound payments that could represent taxable income.
For taxpayers with offshore assets, the practical risk is not only the tax itself. It is also the compliance risk of being unable to prove what the money is, where it came from, and why it should be treated as non-taxable capital or a loan rather than income.
In modern enforcement environments, SARS can also use third-party data and cross-border information exchange mechanisms to identify offshore accounts and foreign inflows, increasing the likelihood that unexplained deposits will be queried.
The legal principle: the onus is on the taxpayer
A key point reinforced in reporting about the SCA judgment is that South African tax law places the burden of proof on the taxpayer in disputes about whether an amount is taxable.
In practical terms, if SARS includes a receipt in taxable income and the taxpayer says it was a loan, a capital repayment, or otherwise not taxable, the taxpayer must prove that claim with credible evidence.
This is where many disputes fail. It is not enough to provide a story after the fact. SARS and the courts will look for contemporaneous documents and objective proof, such as:
- signed loan agreements created at the time the loan was made
- board resolutions and shareholder documentation where corporate structures are involved
- bank records showing the flow of funds
- tax filings that match the narrative
- correspondence that supports the commercial reality of the transaction
If the documentation is incomplete or contradictory, SARS can argue that the taxpayer has not discharged the onus, and the court may accept SARS’s position.
Why the “time passed” argument may not save you
One element highlighted in commentary on the judgment is that the disputed foreign amount was received years earlier, but SARS still pursued the matter after raising concerns through audit activity.
For taxpayers, this matters because it challenges a common assumption that older offshore transactions are safe simply because of the passage of time. Tax outcomes depend on the type of assessment, the facts, and what SARS can prove, but the case illustrates that unresolved offshore issues can surface long after the original transaction.
It is also a reminder that recordkeeping needs to be long-term when cross-border structures and offshore funds are involved. When a taxpayer cannot produce documents because they no longer exist, the default outcome can shift in SARS’s favour.
Penalties can be as damaging as the tax bill
Even where a taxpayer disputes the underlying tax, the penalty exposure can become the largest financial risk.
Under South Africa’s understatement penalty regime, penalties are calculated as a percentage of the tax shortfall and can rise sharply depending on the behaviour category SARS applies and whether the taxpayer’s conduct is viewed as aggravated.
This matters because a taxpayer can be hit from multiple angles:
- additional income tax on the amount SARS treats as taxable
- interest on the tax debt
- understatement penalties, potentially severe where SARS concludes the conduct is serious
- further compliance costs and legal costs associated with objections and appeals
The SCA case has therefore been framed by tax specialists as a warning that trying to assemble an explanation after SARS has started asking questions can be financially devastating, especially if the explanation changes over time or relies on reconstructed records.
The Voluntary Disclosure Programme window
SARS maintains a Voluntary Disclosure Programme (VDP) intended to encourage taxpayers to regularise defaults. The programme is designed to provide relief in certain circumstances, including relief linked to penalties and protection from criminal prosecution for a tax offence arising from the disclosed default, subject to the rules.
The timing point is critical. SARS guidance indicates that if SARS has already started an audit or investigation related to the disclosed default, an application may not be treated as voluntary unless SARS is satisfied the default would not otherwise have been detected and other conditions are met.
The practical takeaway is that VDP is most useful before SARS starts querying a suspicious inflow or begins a lifestyle audit that covers the relevant transaction.
What people with offshore money should do now
This is not a call to panic or to assume every offshore transfer is risky. It is a call to treat cross-border money with the same seriousness as property transfers or major business deals, because the tax consequences can be significant.
A sensible risk-reduction approach includes:
- Confirm tax residency status
Residency determines whether foreign income is within scope. If residency is unclear, professional advice can prevent costly mistakes. - Map offshore assets and income streams
Identify foreign interest, dividends, rental income, capital gains, trusts, and foreign business interests that may trigger reporting or tax consequences. - Strengthen documentation
If funds moved offshore or back into South Africa, ensure you can prove the commercial substance and legal basis of the transaction. - Align tax reporting with banking reality
If your bank statements show a foreign transfer, your tax filings should not contradict the story. Inconsistency is a high-risk trigger. - Consider VDP early if there is a historical default
Where taxpayers suspect non-compliance in offshore matters, early action is safer than waiting for SARS to initiate audit steps.
Why this ruling is likely to increase scrutiny
SARS has increased focus on compliance enforcement, particularly where high-risk indicators exist such as unexplained lifestyle patterns, complex structures, and inbound offshore transfers that do not match declared income.
The SCA judgment strengthens SARS’s position in disputes where taxpayers cannot produce reliable evidence. In practice, this can lead to more aggressive questioning of foreign deposits and a tougher stance on penalties where SARS believes there is obfuscation or late-stage reconstruction of records.
For taxpayers with offshore money, the most valuable protection is simple: a consistent, credible version supported by documents created at the time the transaction occurred.
