Tax Season Has Started, But Don’t Rush
Every July, millions of South Africans receive an SMS or email from SARS informing them that they’ve been automatically assessed for income tax.
For many taxpayers, this sounds like good news. No forms to complete. No paperwork. No queues.
Unfortunately, this is also where many costly mistakes happen.
An auto assessment is generated using information SARS receives from employers, banks, medical schemes, retirement funds and other third-party institutions. While the system has become increasingly sophisticated, it is not perfect.
If important information is missing, you could:
- Receive a smaller refund than you’re entitled to.
- Pay more tax than necessary.
- Miss legitimate deductions.
- Trigger future SARS queries or audits.
Before you click Accept, it’s worth understanding exactly what an auto assessment includes—and what it often leaves out.
What Is a SARS Auto Assessment?
A SARS Auto Assessment is a pre-populated tax return created using information already available to SARS.
Instead of completing your tax return manually, SARS estimates your tax position using data submitted by:
- Employers (IRP5)
- Banks
- Medical schemes
- Retirement fund administrators
- Investment providers
If your tax affairs are relatively straightforward, SARS may issue an assessment automatically.
However, an auto assessment is only as accurate as the information SARS has received.
If information is missing, the assessment may also be incomplete.
Why You Should Never Automatically Accept It
One of the biggest misconceptions during tax season is believing that SARS already knows everything about your finances.
They don’t.
Many deductions and sources of income require you to review or update the assessment before accepting it.
Examples include:
- Home office expenses
- Rental income
- Foreign income
- Travel claims
- Retirement annuity contributions from smaller providers
- Freelance or commission income
Missing deductions mean paying more tax than necessary.
Missing income could create problems later if SARS requests supporting documentation.
Common Mistakes We See Every Tax Season
1. Accepting the Assessment Without Reading It
Many taxpayers simply open the SMS, log into eFiling and click “Accept.”
This can permanently lock in mistakes that could have been corrected beforehand.
Always compare the assessment with your own financial records.
2. Missing Home Office Claims
If you qualify to claim home office expenses, SARS will not automatically calculate these deductions.
Many taxpayers lose thousands of rand simply because they forget to include them.
3. Retirement Annuity Contributions
Not every retirement fund submits data in the same way.
Smaller providers sometimes require additional verification.
If your contribution is missing, your refund may be lower than expected.
4. Rental Income
If you own rental property, SARS expects you to declare the income.
Auto assessments often don’t include complete rental information.
5. Side Hustles and Freelance Income
Selling online.
Consulting.
Freelancing.
Commission work.
These income streams generally need to be declared manually.
Ignoring them can result in penalties later.
How to Review Your Auto Assessment
Before accepting your return, work through this simple checklist.
✓ Compare your IRP5 with your assessment.
✓ Check medical aid information.
✓ Confirm retirement annuity contributions.
✓ Review investment income.
✓ Add rental income where applicable.
✓ Include freelance or business income.
✓ Verify travel claims.
✓ Review any home office deductions.
Only once everything is accurate should you accept the assessment.
Why Professional Review Saves Money
A qualified accountant doesn’t simply complete tax returns.
They look for opportunities.
Professional tax reviews often identify:
- missed deductions
- incorrect income allocations
- supporting documentation issues
- opportunities to reduce tax legally
For many taxpayers, the savings exceed the accounting fee itself.
