The South African Revenue Service (SARS) is intensifying its efforts to improve tax compliance across the nation. As part of these efforts, there are two key groups of taxpayers who are increasingly under scrutiny. These groups face a higher risk of audits and penalties due to a variety of factors, including undeclared income and complex tax arrangements.
Understanding which types of South African taxpayers at risk and how SARS is enhancing its monitoring processes is critical for ensuring compliance. This article provides insights into the two main groups at risk and offers advice on how to avoid falling into SARS’s crosshairs.
1. Taxpayers with Undeclared Secondary Income
One of the primary focuses of SARS is taxpayers who have undeclared secondary income. In South Africa, it’s not uncommon for individuals to earn income from side businesses, freelance work, or rental properties. However, many fail to disclose these income streams when filing their tax returns.
SARS is well aware of these practices and has ramped up its scrutiny in this area, using advanced data analytics and artificial intelligence to cross-check lifestyle indicators with reported income. This means that if a taxpayer’s reported income doesn’t align with their spending habits or lifestyle, they may attract SARS’s attention.
For example, a person who lives in an expensive property or drives a luxury car but reports low income may trigger an audit. SARS can track income through a variety of sources, including third-party reports from employers, banks, and even landlords. This approach makes it harder for individuals to conceal unreported income, and any discrepancies could result in fines or back taxes.

“SARS has increased its capacity to detect discrepancies in income reporting by leveraging sophisticated technology and data analysis tools,” says Edward Kieswetter, SARS Commissioner. “We are committed to ensuring that taxpayers comply with the law by accurately declaring all income sources.”.
To avoid facing SARS scrutiny, it’s crucial for taxpayers to ensure full and honest disclosure of all income, whether from a salaried job, freelance work, or passive income sources such as rental earnings.
2. Entities Engaged in Complex Tax Arrangements
The second group of taxpayers at risk includes businesses involved in complex tax structures. This refers to entities using sophisticated methods such as offshore tax arrangements, transfer pricing, and other international schemes to minimise their tax liabilities. While tax avoidance itself is legal, SARS has become more aggressive in scrutinising these arrangements to ensure compliance with South African tax laws.
SARS has been particularly focused on businesses that engage in aggressive tax avoidance schemes that exploit loopholes in international tax laws. This includes businesses that shift profits to countries with lower tax rates or use other structures to minimise their South African tax obligations.
For example, SARS recently audited a company that was found to have manipulated its pricing agreements with foreign affiliates to avoid tax in South Africa. The result was a tax adjustment of over R1 billion, with severe penalties imposed for non-compliance. This highlights the risks businesses face if they engage in questionable tax practices.

“Companies must ensure that their tax structures are legitimate and compliant with South African tax law,” advises tax expert Arthur Kamp from Sanlam Investments. “SARS has the resources and expertise to track down these arrangements and penalise businesses that attempt to exploit tax loopholes.”.
It is advisable for companies to consult with tax professionals to review their arrangements and ensure that all transactions are priced at arm’s length—i.e., at a fair market value as per international tax standards.

What Does This Mean for South African Taxpayers?
For taxpayers in South Africa, the increased scrutiny by SARS is a reminder of the importance of compliance. While tax audits can be intimidating, it’s important to note that the vast majority of taxpayers will not be subjected to an audit as long as they comply with the law. SARS focuses its efforts on those who are either deliberately underreporting their income or engaging in aggressive tax avoidance.
For individual taxpayers, the key is simple: make sure all income is declared, including side incomes and earnings from passive investments. This may mean revising your tax returns if you’ve failed to disclose certain income streams in the past.
For businesses, it’s essential to regularly review tax structures and ensure that no aggressive tax avoidance tactics are being employed. Keeping up to date with tax regulations and consulting with tax advisors can help mitigate the risks of falling foul of SARS.
How SARS is Enhancing its Monitoring
SARS is not just relying on traditional audits to catch tax evaders. The organisation is increasingly using technology and data analytics to identify high-risk taxpayers. These tools allow SARS to compare taxpayer data with information from other sources, such as banks and third-party financial institutions, to uncover discrepancies that could indicate tax evasion.
Furthermore, SARS has been increasing its presence in tax audits, focusing on high-value taxpayers and those with complex financial arrangements. It’s clear that the organisation is determined to close the revenue gap and ensure that every taxpayer contributes their fair share.
Key Statistics
- In the 2023/24 fiscal year, SARS reported a 25.5% increase in compliance revenue, amounting to R260.5 billion.
- The VAT Voluntary Compliance Index increased to 65.58%, signalling that more businesses are complying with VAT regulations.
Types of South African Taxpayers at Risk
These figures indicate that while the scrutiny has increased, it’s also proving effective in boosting South Africa’s tax revenue.
The two types of South African taxpayers at risk—those with undeclared secondary income and businesses involved in complex tax arrangements—should take heed of the increased scrutiny by SARS. Ensuring full and honest reporting of income and maintaining transparent tax structures are essential for avoiding audits, penalties, and legal trouble.
