Sars has extended the deadline for correcting automatic tax assessments until October 23, 2026, offering taxpayers a chance to review their information. However, this extension does not lessen their responsibility for accuracy.

The South African Revenue Service (Sars) has given taxpayers a little more time to correct automatic assessments ahead of the 2026 filing season. While the extension is a positive development, it should not be confused with a broader relaxation of taxpayers' obligations.
In a notice issued recently under section 95(6) of the Tax Administration Act, Sars extended the deadline for taxpayers who receive automatic assessments to request a reduced or additional assessment until October 23, 2026.
The move comes as Sars prepares to roll out what is expected to be its largest automatic assessment process to date. Between July 1 and 12, 2026, the revenue authority expects to issue approximately six million auto-assessments to qualifying taxpayers.
The extension is significant because it gives taxpayers more time to review the information used by Sars and to identify any omissions or inaccuracies. However, it also serves as a reminder that taxpayers remain responsible for the accuracy of their tax affairs, even when SARS completes much of the administrative work on their behalf.
Over the past few years, automatic assessments have become a central feature of Sars' efforts to modernise tax administration. Using information received from employers, banks, medical schemes, retirement funds, insurers, and other third-party institutions, Sars can calculate a taxpayer's liability without requiring them to submit a return.
For many salaried employees with relatively straightforward tax affairs, the process has simplified the filing season considerably. If the information received by Sars is complete and accurate, there may be no further action required.
However, taxpayers should understand that an automatic assessment is not necessarily a final or flawless assessment.
The system relies entirely on the quality and completeness of the data submitted to Sars by third parties. Where information is missing, outdated, or incorrectly reported, the resulting assessment may not accurately reflect a taxpayer's position.
This is particularly relevant for taxpayers with more complex financial arrangements. Income earned from freelance work, consulting, rental properties, investments, foreign sources or side businesses may not always be fully reflected in an automatic assessment. Similarly, certain deductions or tax credits may require verification.
The consequence of accepting an inaccurate assessment can be significant. A taxpayer may pay more tax than necessary, receive a smaller refund than they are entitled to, or potentially face penalties and interest if income has not been correctly declared.
The extension to October 23, therefore, provides taxpayers with a valuable opportunity to review assessments carefully before matters become more complicated.
Importantly, Sars has made it clear that taxpayers who disagree with an automatic assessment should not simply ignore it. Where corrections are required, taxpayers should submit the necessary information as soon as possible rather than waiting until the deadline approaches.
The development also reflects the increasing sophistication of Sars' data-driven approach to tax administration.
In recent years, the revenue authority has invested heavily in technology, data analytics, and third-party reporting systems. Financial institutions, employers, medical schemes, and investment providers are required to submit large volumes of taxpayer information directly to Sars. This enables the revenue authority to pre-populate returns and identify discrepancies more efficiently than in the past.
According to Sars, the objective is to make compliance easier for taxpayers while improving the accuracy of assessments and reducing administrative burdens.
The system has undoubtedly delivered benefits. Millions of taxpayers no longer need to complete lengthy returns, and refunds can often be processed more quickly. At the same time, the responsibility for ensuring that an assessment is correct has not shifted from the taxpayer to Sars.
That principle remains unchanged.
The extension announced by Sars should therefore be viewed as an additional compliance safeguard rather than a reason to delay reviewing tax information.
With six million automatic assessments expected to be issued during the first two weeks of July, taxpayers would be wise to review any assessment as soon as it becomes available. Checking income details, retirement contributions, medical tax credits, investment income, and banking information can help identify potential errors early and avoid unnecessary disputes later.
The message from Sars is clear: automatic assessments are designed to simplify tax administration, but they do not remove the taxpayer's responsibility to verify the accuracy of the information on which those assessments are based.
The additional time granted until October 23 is useful. However, the most effective approach remains the simplest one: review your assessment early, correct any errors promptly, and ensure your tax affairs accurately reflect your financial position.
