Every year, SARS audits many South Africans because of simple, avoidable tax mistakes. In 2025, SARS will use more advanced tools such as AI and data matching. Therefore, even small errors can trigger an audit. If you want to avoid getting your SARS tax return audited in 2025, you must avoid these seven common mistakes.
1. You Underreport Your Income
First and foremost, underreporting income remains a top reason SARS audits taxpayers. SARS receives income information directly from your employer, bank, and other sources. So, if your declared income doesn’t match their data, they will flag your return.
For example, if you earn extra money from freelancing, renting property, or side jobs but leave it out, you increase your audit risk.
How to avoid it: Always track and declare all income streams accurately. Don’t assume small earnings don’t count-they do.
2. You Submit Incomplete or Incorrect Documents
Secondly, submitting incomplete or incorrect supporting documents puts you at risk. SARS requires proof for deductions like medical expenses or donations. If your documents are missing, unclear, or invalid, you could get your SARS tax return audited in 2025.
In fact, ban.co.za highlights that missing documentation frequently triggers SARS audits, especially for VAT.
How to avoid it: Organise your documents carefully. Keep receipts, invoices, medical aid statements, and donation certificates ready and easy to access.
3. You Overclaim Tax Deductions
Moreover, overstating deductions can attract SARS’s attention. For instance, if your travel expenses seem too high compared to your income, SARS will likely question your claim.
Overclaiming deductions will get your SARS tax return audited in 2025 and may even lead to penalties.
How to avoid it: Claim only what you can prove. Maintain logbooks, petrol slips, and valid receipts to support your expenses.
4. You Make VAT Errors (For Businesses)
If you run a business or freelance and registered for VAT, you must avoid errors in VAT returns. SARS closely reviews VAT submissions and flags incorrect claims, such as input VAT on non-qualifying items.
Furthermore, ban.co.za reports that VAT misreporting remains a common reason for SARS audits.
How to avoid it: regularly check your VAT returns against invoices. Consult a tax professional to ensure accuracy.
5. You Don’t Declare Capital Gains
In addition, many taxpayers fail to report capital gains from selling assets like property or shares. Even small profits must be declared to SARS.
Failing to report these sales can result in your SARS tax return being audited in 2025 because SARS receives transaction information from third parties.
How to avoid it: Always disclose asset sales. Use SARS’s CGT calculator to determine your tax liability.
6. You File Late or Don’t File At All
Also, submitting your tax return late or not filing can land you in hot water. SARS imposes penalties on late returns and may flag repeat late filers for audits.
Therefore, missing deadlines increases the chance that SARS will audit your return.
How to avoid it: submit your tax return on time. The deadlines for 2025 are October 31 for non-provisional taxpayers and January 31, 2026, for provisional taxpayers.
7. You Provide Inconsistent Information
Finally, inconsistencies between your current and past tax returns raise red flags. For example, if your expenses suddenly jump without explanation, SARS will want to investigate.
In addition, mismatches between your employer’s IRP5 and your declared income may trigger an audit.
How to avoid it: Keep your tax information consistent year over year. If your situation changes, be prepared to explain and provide proof.
