Tax Season 2026 is officially here, and millions of South Africans may receive a SARS Auto Assessment instead of having to submit a tax return manually.
While Auto Assessment makes tax filing faster and easier, many taxpayers make the mistake of assuming that SARS has all their information and that their assessment is automatically correct.
Unfortunately, that is not always the case.
If you receive a SARS Auto Assessment in 2026, it is your responsibility to review it carefully before deciding that no further action is required. An incorrect assessment could result in a reduced refund, additional taxes owed, penalties, or missed deductions.
In this guide, we’ll explain exactly how SARS Auto Assessment works, common mistakes to look out for, and what to do if your assessment is incorrect.
What Is A SARS Auto Assessment?
A SARS Auto Assessment is a pre-calculated tax assessment generated using information SARS receives from third parties such as:
- Employers
- Banks
- Medical aid schemes
- Retirement funds
- Insurance providers
- Investment institutions
SARS uses this information to calculate your tax position and issues an assessment without requiring you to complete a tax return manually.
For the 2026 filing season, Auto Assessments will be issued between 1 July and 12 July 2026.
How Do I Know If I Have Been Auto Assessed?
SARS will notify qualifying taxpayers via:
- SMS
- SARS eFiling
- SARS MobiApp
You can also check your status using the SARS Online Query System.
If you do not receive an Auto Assessment notification by 12 July 2026, you will need to file your tax return during the normal filing season period.
Do You Need To Accept A SARS Auto Assessment?
One of the most common misconceptions is that taxpayers must “accept” their Auto Assessment.
If all the information is correct, there is generally no action required. SARS will process any refund automatically or advise you of any amount owing.
However, before doing nothing, you should carefully review every aspect of the assessment.
SARS Auto Assessment Incorrect? Here’s What To Check
Before accepting the assessment as accurate, review the following:
Employment Income
Check that:
- All IRP5 certificates are included.
- Salary figures are accurate.
- Bonuses and allowances have been captured correctly.
Investment Income
Verify:
- Interest income
- Dividends
- Investment earnings
- Foreign income where applicable
Medical Aid Information
Ensure that:
- Medical aid contributions are reflected correctly.
- Dependants are correctly listed.
- Additional medical expenses are included where relevant.
Retirement Contributions
Confirm that:
- Retirement annuity contributions are reflected.
- Pension and provident fund contributions are accurate.
Additional Income
Many Auto Assessment errors occur because SARS may not have complete information regarding:
- Rental income
- Freelance income
- Side businesses
- Commission earnings
- Consulting income
Taxpayers remain legally responsible for declaring all taxable income even if SARS does not include it in the Auto Assessment.
Common Reasons Why A SARS Auto Assessment Is Wrong
While SARS receives information from multiple sources, mistakes can still occur.
Some of the most common issues include:
Missing Tax Certificates
Third-party providers may submit information late or incorrectly.
Incorrect Employer Information
Errors on an employer’s IRP5 can affect the entire assessment.
Missing Deductions
Auto Assessments may not fully account for deductible expenses or tax benefits that apply to your circumstances.
Additional Sources Of Income
If SARS does not have complete records of all income earned during the year, the assessment may be incomplete.
What Should You Do If Your SARS Auto Assessment Is Incorrect?
If you disagree with your assessment:
Step 1: Gather Supporting Documents
Collect:
- IRP5 certificates
- Medical aid certificates
- Retirement annuity certificates
- Investment certificates
- Proof of additional income
Step 2: Review The Assessment
Identify exactly what information is missing or incorrect.
Step 3: Submit An Updated Tax Return
You can amend the information by submitting your ITR12 through:
- SARS eFiling
- SARS MobiApp
SARS specifically allows taxpayers to update incorrect Auto Assessments by filing an amended return.
Step 4: Keep Supporting Documentation
SARS may request supporting documentation during a verification process.
Always retain all relevant records and certificates.
What Happens If You Ignore An Incorrect Auto Assessment?
Ignoring an incorrect assessment can create problems later.
Potential consequences include:
- Additional tax liabilities
- Interest charges
- Administrative penalties
- SARS verification requests
- Reduced refunds
Remember, the responsibility for the accuracy of your tax affairs remains with the taxpayer, even when SARS performs the Auto Assessment.
Should You Use A Tax Practitioner?
Many taxpayers assume Auto Assessments eliminate the need for professional tax assistance.
However, if you have:
- Multiple income streams
- Rental income
- Investments
- Capital gains transactions
- Retirement contributions
- Complex tax affairs
it may be worthwhile having a registered tax practitioner review your assessment before finalising your tax affairs.
A professional SARS Tax Assessment Review can often identify missing deductions, reporting errors, and opportunities to improve compliance.
