Six million taxpayers in South Africa benefit from the convenience of automated assessment during tax season, but Sanjit Hannuman raises concerns about whether they are exposing themselves to the risk of costly errors.
Positive Aspects of Automated Assessment
During the first two weeks of the current tax period, SARS automatically assessed 1.9 million taxpayers, issuing approximately 8 billion early payments. These funds often reach bank accounts within 72 hours, eliminating queues, form filling, and stress for millions of employees for whom tax season concluded with a single SMS.
Automated assessment is a process where SARS independently generates a tax return using data received from employers, medical insurers, pension funds, and the taxpayer's bank. If a taxpayer was selected for such an assessment, they received a notification via SMS or email between July 1 and 12 regarding whether they were due a refund or owed SARS money. Provided the data is correct, no further action is required from them, and the refund is processed automatically.
Improvements and Review Timelines
The new Commissioner, Dr. Johnston Makubu, announced several improvements beneficial to taxpayers. The deadline to appeal or amend an automated assessment has been extended to October 23, 2026, aligning with the general filing deadline, provided the assessment was issued before August 27. Previously, taxpayers had a much tighter window for such actions.
Furthermore, for the first time, automated assessment has been expanded to certain temporary categories of taxpayers with more complex financial operations, such as rental or investment income, following a trial period that began in 2025. The addition of a simplified declaration, a dropdown list of medical schemes to reduce errors, and the ability to view the Assessment Notice and upload documents via WhatsApp indicates modernization by the tax authority.
Risks: Limitations of SARS Information
Despite the convenience, there is a significant drawback: automated assessment relies solely on information provided by third parties to SARS, and SARS does not have a complete picture of an individual's financial situation. Last year, 99.6% of taxpayers who underwent automated assessment accepted it without changes, which, according to the author, is more a sign of blind faith than accuracy.
South Africans tend to assume that receiving a figure from SARS means it is flawless, yet the legal responsibility for the correctness of the assessment lies with the taxpayer, not with SARS, the employer, or the medical insurer. SARS does not see medical expenses paid from personal funds, nor does it account for a home office under a qualified work arrangement, donations to registered charities, accounts to confirm travel expenses, or contributions to pension annuities made directly, rather than through a payslip.
System Traps and Errors
Tax Director at Hobbs Sinclair, Daniel Luwes, warned that the absence of these deductions could lead taxpayers to overpay taxes or lose legitimate reimbursements. Of particular danger is the carry-over of pension annuity contributions exceeding the annual limit from the previous year; if this carried-over amount is incorrectly linked to the current assessment, the deduction will simply disappear without any warning.
More alarming are instances where a Durban chartered accountant discovered six errors in automated assessments during the first week of the season, including unrecorded medical contributions and pension annuities. There were also reports of cases where taxpayers who voluntarily paid provisional tax received a full refund of their payment, even though they still owed money. Additionally, issues arose with tax fund directives, causing lump-sum payments from pension funds to be erroneously shown as taxable in automated assessments, creating false tax debts for pensioners.
Consequences of Incorrect Declaration
If a taxpayer accepts an automated assessment that omits income—such as rent from a grandmother's apartment or freelance income—they are making a false declaration. In the event of a subsequent audit by SARS, whose data matching capabilities are constantly growing, they may face penalties up to 200% of the tax amount plus interest. A refund received within 72 hours can turn into a very expensive debt.
In conclusion, the author advises against rejecting the technology but rather verifying it: log into eFiling or MobiApp and cross-check every figure against IRP5 certificates, medical insurance, and pension fund statements. You must ask yourself two questions: is there income that SARS does not see, and are there deductions that SARS is unaware of? If the answer is yes, you should submit a corrected return by October 23, 2026. If no automated assessment was performed at all, the submission must be done independently, as the filing window opened on July 13. For complex financial situations, consulting a professional is recommended, as the cost of consultation is almost always lower than the cost of an error.
