SARS Auto Assessments 2026 — Everything You Need to Know & What to Do
SARS auto-assesses millions of South African taxpayers every year. Here is exactly what it means, how to check if it is correct, and what to do if it is wrong.
A SARS auto assessment is when SARS automatically files your ITR12 tax return on your behalf using third-party data — from your employer (IRP5), medical aid fund, retirement fund, and banks. SARS sends you an SMS/email notification. You then have a set window to either accept it or edit and resubmit your own return if the auto assessment is incorrect.

What is a SARS Auto Assessment?
A SARS auto assessment is an automatic tax return that SARS files on your behalf using data it has already received from third parties — your employer, medical aid fund, retirement annuity administrator, and banks. SARS introduced auto assessments in 2020 to simplify the filing process for taxpayers with straightforward tax affairs.
SARS uses this third-party data to calculate your tax liability and issues a provisional assessment. If you owe tax, SARS expects payment. If you are due a refund, SARS will pay it — provided your banking details are verified and there are no outstanding issues on your account.
Importantly, an auto assessment is not final until the filing season deadline passes. You have the right to review and edit your auto assessment at any time during the filing window. This article was last updated in April 2026 to reflect the latest SARS processes and 2026/2027 tax year rules.
Who Gets a SARS Auto Assessment?
SARS selects taxpayers for auto assessment based on the complexity of their tax affairs. You are likely to receive an auto assessment if:
You qualify for auto assessment if you have:
- Only one employer and one IRP5 certificate
- Medical aid contributions reported to SARS by your fund
- Retirement annuity contributions reported by your RA administrator
- Bank interest income reported by your bank
- No additional income sources (rental, freelance, foreign income)
- No complex deductions (home office, travel allowance logbook)
- No capital gains to declare
How the SARS Auto Assessment Process Works
Accept or Edit — What Should You Do?
This is the most important decision when you receive an auto assessment. Here is a clear framework:
| Your Situation | Action | Reason |
|---|---|---|
| Only one employer, no extra income, medical aid correct | Accept | Auto assessment is likely accurate |
| Rental income not included | Edit and resubmit | Rental income must be declared — SARS does not have this data |
| Freelance / commission income missing | Edit and resubmit | Must declare all income — not declaring is a risk of additional assessment |
| Medical aid contributions wrong | Edit and resubmit | Incorrect MTC will result in wrong tax — under or overpayment |
| RA deduction missing or wrong | Edit and resubmit | RA deduction reduces taxable income — do not miss it |
| Travel allowance / logbook claim | Edit and resubmit | Auto assessment cannot include logbook km — must be manually entered |
| Home office deduction to claim | Edit and resubmit | Must be added manually with supporting calculations |
| Capital gains to declare | Edit and resubmit | CGT from property or shares must be declared manually |
Step-by-Step: How to Check Your Auto Assessment on eFiling
Common Auto Assessment Errors to Watch For
SARS auto assessments are based on third-party data — which can contain errors. These are the most common mistakes found in auto assessments:
Wrong medical aid credits
If your medical aid fund reported incorrect contribution amounts or member counts to SARS, your MTC will be wrong — affecting your final tax by hundreds or thousands of rands.
Missing RA contributions
If your RA administrator did not report your contributions to SARS in time, your deduction may be missing — resulting in higher taxable income and more tax than you actually owe.
Incorrect IRP5 amounts
Employer errors on the IRP5 — wrong salary amounts, incorrect PAYE deducted, or missing allowances — flow directly into your auto assessment and must be corrected by your employer.
Missing income sources
SARS only includes data it has received. Rental income, freelance income, and foreign income are not automatically included — you must add these manually by editing your return.
Wrong bank interest
Banks report interest income to SARS — but the amounts sometimes differ from your actual statement. Always verify the interest amount against your bank’s tax certificate.
Multiple employers not merged
If you changed jobs during the year, both IRP5s must be included. SARS sometimes misses one — always check that all IRP5s for the year appear in your return.
2026 Auto Assessment Deadlines
SARS typically opens the auto assessment season in July each year. Key 2026 dates to remember:
| Event | Typical Date | Notes |
|---|---|---|
| Auto assessments issued | July 2026 | SARS sends SMS/email notification |
| Filing season opens | July 2026 | eFiling and MobiApp open for editing |
| Deadline — non-provisional taxpayers | October 2026 | Accept or edit by this date |
| Deadline — provisional taxpayers | January 2027 | Extended deadline for provisional taxpayers |
| Refund payment | Within 21 business days | After assessment is finalised |
Auto Assessment Refunds — What to Expect
If your auto assessment shows a refund, SARS will pay it to your verified bank account — usually within 21 business days of the assessment being finalised. Key points:
Banking details must be verified
SARS will only pay refunds to a verified bank account in your own name. If your details are not verified, update them on eFiling before accepting your auto assessment.
Outstanding debts are offset first
If you have any outstanding SARS debt, your refund will be offset against it before any balance is paid to you. Check your account for outstanding items before expecting a payment.
Refund may trigger verification
SARS may select your return for verification before releasing a refund — even for auto assessments. Submit all requested documents promptly via eFiling.
Edit may increase your refund
If your auto assessment missed a deduction — such as an RA contribution or additional medical expense — editing your return may increase your refund significantly.
