As the automatic assessment period from the South African Revenue Service (SARS) approaches its end, taxpayers are strongly urged not to rush into filling out tax returns and not to rely solely on the completeness of information pre-filled by the tax authority.
Automatic assessment has simplified the filing process for millions of South Africans, but careless review of the data can lead to delays in receiving refunds, penalties, the emergence of additional tax liabilities, or audits by SARS.
The first and perhaps most significant mistake for those receiving an automatic assessment is accepting it without thoroughly checking the correctness of all submitted information. Although SARS receives data directly from employers, banks, medical insurance companies, and other parties, there is a possibility of incomplete or erroneous information.
Taxpayers must cross-reference the received assessment with documents such as IRP5, medical insurance certificates, pension annuity certificates, and investment reports before agreeing to it. Another common mistake is failing to declare all sources of income. Many assume that SARS has a complete picture of their financial situation, but additional income from freelancing, property rentals, consulting, side businesses, or certain foreign income may still require declaration.
Similarly, individuals who sold property, shares, unit trusts, or cryptocurrency during the tax year must ensure that any applicable capital gains or taxable crypto income is correctly reflected in their return. Taxpayers are also warned against claiming deductions for which they are not entitled.
Home office expenses remain one of the most confusing tax deductions; strict SARS rules require a dedicated workspace used exclusively and regularly for work. Likewise, an accurate and up-to-date logbook is necessary to claim travel deductions, whereas personal expenses cannot be counted as business costs. On the other hand, some taxpayers miss out on legitimate tax benefits by not declaring allowable deductions or credits, including pension annuity contributions, qualified medical expenses not covered by medical insurance, and donations to approved public charities.
Administrative oversights continue to cause delays in return processing. These include entering incorrect bank details, failing to update contact information such as mobile numbers or email addresses, uploading incomplete or illegible supporting documents, and accidentally submitting certificates for the wrong tax year.
Taxpayers are also advised to carefully monitor correspondence from SARS after submitting returns. Ignoring verification requests or failure to provide supporting documents can delay refunds and, in some cases, lead to estimated assessments or administrative fines if deadlines are missed. Another common error is waiting until the last days before the submission deadline. Submitting documents at the last minute leaves little time to correct errors, respond to SARS queries, or obtain missing documentation if verification is required.
To avoid unnecessary complications, taxpayers should review every automatic assessment before accepting it, ensure all income sources are declared, verify that claimed deductions are supported by the required documentation, confirm the accuracy of banking and personal details, respond promptly to any SARS requests for additional information, and keep all supporting tax records for at least five years in case of a SARS inquiry. Taking a few minutes to check the information before clicking 'submit' will help avoid costly mistakes and delays during the filing period.
The tax season has begun, and the South African Revenue Service (SARS) has already conducted an automatic assessment for approximately 1.9 million taxpayers.
Although many citizens receive ready-made calculations, some taxpayers remain outside this system. Previously, IOL reported that around six million taxpayers were expected to be automatically assessed during 2026. SARS Commissioner, Dr. Johnstone Makubu, also stated that the automatic assessment program has been expanded and will now include another 200,000 temporary taxpayers with relatively simple tax affairs.
Automatic assessment allows the revenue service to use data obtained from employers, banks, medical schemes, pension funds, and other third-party data providers to automatically calculate a taxpayer's tax position. Taxpayers selected for this assessment receive notifications from SARS in groups and can view their calculations via eFiling or the SARS MobiApp mobile application.
According to SARS, by the end of July 1, 2026, over 1.9 million taxpayers had undergone automatic determination, and approximately 8 billion in tax refunds were paid within the first 72 hours after the start of the tax season.
However, not everyone will be able to utilize the automatic assessment system. The service indicated that the process only functions if the taxpayer's information is complete, consistent, and verified through third-party data sources, such as banks and employers.
SARS emphasized that automatic assessment will not be provided if personal information is incomplete (details can be updated on eFiling). Furthermore, automatic assessment does not apply if income is not derived from employment and investments, such as rental income. In fact, automatic assessment is intended for taxpayers with simple financial matters whose income can be verified by third parties. Taxpayers with complex financial affairs, missing information, or income that SARS cannot automatically verify will generally have to file a tax return during the regular season.
Specifically, taxpayers receiving business income or foreign income, having capital gains, multiple sources of income, or other information that cannot be verified through third-party data, are generally not suitable for automatic assessment.
With the start of the annual tax return filing season in South Africa, millions of taxpayers are required to submit their returns to the South African Revenue Service (SARS). While some taxpayers undergo automatic assessment between July 1 and July 12, 2026, others must submit documents manually before the deadline.
It is important to understand that not all taxpayers are obligated to file a return. SARS automatically assesses many citizens using data received from employers, banks, medical schemes, pension funds, and other third parties. If your tax affairs are simple and you agree with the automatic assessment, filing a return may not be necessary.
However, those who are required to file a return must do so by the date announced by SARS. This category includes individuals receiving additional income, self-employed persons, those with rental income, foreign income, or those with more complex tax circumstances.
If you fail to file a return on time when required, SARS may impose a range of penalties, including administrative sanctions, interest on unpaid tax, and the possibility of debt recovery.
One of the quickest consequences is a monthly administrative penalty. These penalties accrue every month the return remains unfiled and can continue for up to 35 months. The penalty amount depends on your taxable income and ranges from R250 to R16,000 monthly. The situation is aggravated by the fact that the longer the return is not filed, the more expensive it becomes.
If you owe money to SARS and do not pay it by the due date, interest begins to accrue on the unpaid amount. This interest continues to grow until the tax debt is fully settled, increasing the total outstanding amount. In some cases, SARS may also impose additional penalties for unpaid taxes.
Persistent non-compliance can lead SARS to take steps to recover outstanding tax debts. These measures may include direct debiting from your bank account, requiring your employer to withhold funds from your salary, appointing a third party, such as a bank or employer, to pay SARS on your behalf, as well as seizing and selling assets subject to necessary legal procedures.
Willful failure to submit tax returns or persistently ignoring correspondence from SARS can expose taxpayers to more serious consequences. According to the Tax Administration Act, non-compliance in certain cases can lead to criminal prosecution, especially if there is evidence of intentional tax evasion, fraud, or providing false information. Sentences may include fines or imprisonment, depending on the nature and severity of the offense.
Yes, even if you have missed the deadline, taxpayers should file their outstanding return as soon as possible. A late submission does not automatically cancel already imposed penalties, but it prevents the endless accumulation of additional monthly penalties and helps taxpayers get their tax affairs in order faster.
If there is a tax debt, timely payment also limits the amount of interest that continues to accrue. However, if you cannot pay your tax debt immediately, you should not ignore SARS. The Revenue Service offers payment arrangement options in appropriate cases, allowing taxpayers to repay unpaid taxes over a specified period instead of a lump sum.
Taxpayers experiencing financial difficulties are advised to contact SARS in advance rather than waiting for enforcement action. In certain circumstances, SARS may waive or reduce administrative penalties if taxpayers can demonstrate valid reasons for their non-compliance. Each application is considered individually, and supporting documentation may be required. Nevertheless, taxpayers should not assume that penalties will be automatically waived simply because they eventually file their return.
