| Key takeaways SARS issues auto-assessments from 1 to 12 July 2026. No notification by 12 July means you are not auto-assessed. Auto-assessments are built only from third-party data and often miss deductions like home-office costs, travel and donations. Accept an incomplete one and you may overpay, or under-declare and inherit a problem later. You remain responsible for accuracy even if you accept. You have 40 business days to amend. New for 2026: eligible provisional taxpayers can be auto-assessed too. |
It feels almost too easy. A message arrives from SARS, your assessment is already calculated, and a single tap makes it all go away. Convenient? Absolutely. Always correct? Not necessarily, and the gap between those two things is where careful taxpayers either quietly overpay or unknowingly create a problem.
What is a SARS auto-assessment?
A SARS auto-assessment is a pre-calculated tax return that SARS prepares for you using third-party data (your IRP5, bank interest, medical aid and retirement-fund contributions) and sends you to accept or amend. In 2026 they are issued between 1 and 12 July, before the general filing season opens on 13 July.
It’s impressive automation. The catch is simple: SARS can only calculate from what it can see.
What does a SARS auto-assessment miss?
An auto-assessment typically has no knowledge of deductions and income that don’t come from third-party data, including:
- Home-office expenses, if you qualify
- Business travel and a logbook for vehicle claims
- Rental income, or rental losses
- Out-of-pocket medical expenses beyond your scheme contributions
- Donations to registered public benefit organisations
- Freelance or side income, and the expenses against it
Two outcomes follow. Accept an assessment that omits deductions you’re owed and you overpay. Accept one that omits income you should have declared and you’ve under-declared, which becomes your problem to fix later, potentially with penalties and interest.
Should I just accept my SARS auto-assessment?
Only after reviewing it. If it includes all your income and the deductions you’re entitled to, accepting is fine; if anything is missing, file an amended return within 40 business days instead. Accepting is a decision, not a default.
Crucially, SARS is explicit that even when you accept an auto-assessment, you remain responsible for ensuring your income, deductions and rebates are complete and correct. The convenience doesn’t transfer the responsibility.
Why provisional taxpayers should be extra careful in 2026
For the first time in 2026, SARS is auto-assessing eligible provisional taxpayers, a group that usually has more complex affairs: business income, multiple income streams, investments. The more moving parts in your finances, the less likely a pre-populated figure captures them accurately. If you’re a provisional taxpayer and an auto-assessment lands, treat it as a signal to review with extra care.
What to check before you tap “accept”
- Is the income complete? Every employer, bank account and income source for the year.
- Are your deductions there? Retirement annuity, medical, home office, travel, donations.
- Does the refund or amount due feel right? A surprisingly large refund or unexpected bill both deserve a second look.
- Has anything changed this year? A new property, a side business, a change in how you work, exactly what auto-assessment tends to miss.
If everything genuinely checks out, accepting is fine. If not, you file an amended return, and that’s where having someone in your corner helps. If a review later turns into a query, see our guide to handling a SARS audit.
Frequently asked questions
Should I accept my SARS auto-assessment?
Only after reviewing it. If all your income and entitled deductions are included, accepting is fine. If anything is missing, file an amended return within 40 business days.
When are SARS auto-assessments issued in 2026?
Between 1 and 12 July 2026. If you receive no notification by 12 July, you are not auto-assessed and should file from 13 July.
Can a SARS auto-assessment be wrong?
It’s usually not “wrong” but incomplete: built only from third-party data, it can miss deductions such as home office, travel or medical, leading you to overpay.
Am I still responsible if I accept an incorrect auto-assessment?
Yes. SARS holds you responsible for the accuracy and completeness of your return even when you accept an auto-assessment.
