The Supreme Court of Appeal (SCA) has delivered a judgment that reinforces SARS’ strict stance on understatement penalties and estimated assessments. The ruling confirms the South African Revenue Service (SARS)’s authority when taxpayers fail to provide accurate information. SCA confirms SARS’ firm approach to enforcement and compliance.
In Ntayiya vs SARS [2025] ZASCA 183, the court dismissed an appeal brought by a taxpayer. He sought repayment of funds attached by SARS. He also attempted to challenge a 150 percent understatement penalty linked to six consecutive nil returns.
The decision sends a clear message. When taxpayers submit incorrect returns, fail to substantiate their positions, or abandon key dispute grounds, SARS may impose penalties and enforce collection measures. SCA confirms SARS’ firm approach to non-compliance.
Background
The taxpayer, an attorney, submitted nil returns for the 2008 to 2013 tax years. SARS audited his bank statements.
The audit revealed taxable income during the same period. SARS issued assessments and imposed a 150 percent understatement penalty for intentional tax evasion. Later, the taxpayer submitted revised financial statements prepared by new accountants. However, these revisions did not materially change the assessed liability or the penalties.
During litigation, the taxpayer abandoned relief aimed at challenging the correctness of the original assessments. As a result, the assessments became final under section 100 of the Tax Administration Act.
The SCA’s key findings
The Court confirmed that the understatement penalty was justified. SARS identified income inflows, vehicle purchases, and an affidavit in which the taxpayer claimed to have earned no income. The taxpayer provided no credible evidence of a bona fide error. Consequently, the penalty for intentional evasion remained appropriate. SCA confirms SARS’ firm approach to intentional understatement.
The Court also upheld SARS’ ten percent private-use adjustment on the taxpayer’s motor vehicles. The taxpayer produced no logbooks or supporting records. SARS therefore relied on an estimate proposed by the taxpayer’s own accountants.
In addition, the SCA rejected an attempt to introduce new evidence concerning the attachment of the law firm’s bank account. The firm is a separate legal entity. It was not a party to the appeal. The evidence would not have altered the outcome.
Why this judgment matters
The judgment reaffirms several key principles:
- Nil returns must be supported by proper records.
- Claims of inadvertent error require credible evidence.
- Revised financial statements do not displace final assessments without proper prosecution.
- SARS may issue estimated assessments when information is incomplete.
- Taxpayers cannot conflate entities to justify set-off against personal tax debt.
For taxpayers, the ruling serves as a caution. Procedural missteps can be as damaging as substantive errors. Once an assessment becomes final, challenging penalties becomes extremely difficult.
The role of specialist tax attorneys
This case highlights the risks taxpayers face when disputes lack strategic management and proper documentation. From understatement penalties to ADR, objections, and appeals, specialist tax attorneys ensure arguments are framed correctly. They also ensure deadlines are met and appropriate remedies are pursued.
In the current enforcement climate, professional representation has become essential. It helps protect taxpayers against penalties, asset attachments, and unnecessary financial exposure.
