Tax Filing Season 2026: Auto-Assessments & What You Need to Know
Tax Filing Season 2026: Auto-Assessments & What You Need to Know
The 2026 tax filing season in South Africa is now underway, bringing significant changes for millions of taxpayers. The South African Revenue Service (SARS) has expanded its use of auto-assessments and introduced a new declaration alert questionnaire to identify discrepancies early.
This guide breaks down everything you need to know, from key dates to common pitfalls.
Key Dates for Tax Filing Season 2026
| Taxpayer Category | Auto-Assessment Period | Filing Period |
|---|---|---|
| Auto-Assessed Individuals | 1 July – 12 July 2026 | 13 July – 23 October 2026 (to correct/return) |
| Non-Provisional Taxpayers (salary earners, not auto-assessed) | N/A | 13 July – 23 October 2026 |
| Provisional Taxpayers (rental, interest, foreign income, etc.) | N/A | 13 July 2026 – 22 January 2027 |
What’s New in 2026?
1. Declaration Alert Questionnaire
This is a new pre-verification alert. It serves as a warning that SARS may have detected a mismatch between the third-party data they hold and what you have declared.
Expert Advice: Nico Theron of Unicus Tax Specialists says, “It is important to pay careful attention to the questionnaire… If you choose to ignore it and there are errors in the return, it is highly likely that you will receive an assessment that you disagree with.”
2. Expanded Auto-Assessments
SARS is using more third-party data than ever before to pre-populate returns. However, this data is only as complete as the information provided by employers, medical schemes, and financial institutions.
3. Other Improvements for 2026
- More pre-filled third-party data (e.g., investment income).
- Simplified returns with clearer questions.
- A dropdown list of approved medical-aid schemes to reduce errors.
- Delivery of assessment notices via WhatsApp.
Auto-Assessment: What’s Included & What’s Missing
Auto-assessments are generated from data SARS receives from third parties, including:
- IRP5 tax certificates (from employers)
- Medical-aid certificates
- Retirement-annuity fund certificates
- Investment-income certificates (from banks and financial institutions)
Important: Andre Bothma from TaxTim warns that if income or deductions are not in this third-party data, they will not be included in your auto-assessment. It is your responsibility to correct this.
Income and Deductions Often Missing from Auto-Assessments
| Category | Examples |
|---|---|
| Missing Income (Must declare) | Rental income, freelance/self-employment/side-hustle income, foreign income. |
| Missing Deductions (Claim to save tax) | Qualifying out-of-pocket medical expenses, home-office expenses, business travel claims (against a travel allowance), direct RA contributions (not reported by fund). |
Key Insight: Missing income can lead to under-declaration and SARS queries. Missing deductions means you are leaving money on the table.
Who is Most Likely to Get a Declaration Alert?
- High-wealth individuals
- Taxpayers with multiple income streams (e.g., rental, interest, and dividends)
- Those with more complex tax returns that are prone to closer scrutiny.
What to Do If You Disagree with Your Auto-Assessment
Do not ignore it. Once the correction period has passed, the assessment stands.
- Do not try to correct third-party data yourself. If your IRP5 or medical certificate is wrong, the provider must correct and resubmit it to SARS.
- Submit a corrected return during the filing period (from 13 July to 23 October for most individuals).
- Ensure your return is accurate before submitting to avoid future verification or audit.
5 Quick Tips for a Smooth Filing Season
- Check Your Auto-Assessment Carefully: Review all pre-filled data for accuracy.
- Don’t Ignore the Alert Questionnaire: Address it proactively to avoid future disputes.
- Gather All Documents: Have your IRP5, medical certificates, RA certificates, and records of any additional income or deductions ready.
- Correct Missing Data: Add income not pre-filled and claim all legitimate deductions you qualify for.
- Act Before the Deadline: Especially for complex returns, start preparing early.
