Should You Accept the SARS Auto-Assessment? Key Considerations Before Making a Decision

Before clicking “accept” on your SARS auto-assessment for 2025, here’s what every South African taxpayer needs to know.
Tax Season 2025
The 2025 tax season officially kicks off on 7 July, and like in previous years, the South African Revenue Service (SARS) is sending out auto-assessments to many taxpayers. These assessments are based on the data SARS already has — mostly from employers, banks, and medical aids.
On the surface, clicking “accept” may seem quick and convenient. But here’s the million-rand question: Is it accurate? And will it save or cost you money in the long run?
Let’s unpack what you need to look out for before hitting accept.
1. Donations to Public Benefit Organisations (PBOs)
Did you donate to a registered charity or cause? If you received a Section 18A certificate, you’re entitled to a tax deduction.
⚠️ But beware: SARS does not include these in your auto-assessment. You need to claim them manually to reduce your taxable income. Skipping this step? That’s money down the drain.
2. Work-from-Home? Don’t Forget Home Office Deductions
Remote workers and freelancers, this one’s for you. If you meet the SARS requirements to claim home office expenses — such as having a dedicated workspace and spending more than 50% of your work hours there — you’re eligible for deductions.
❗These are not pre-populated in your auto-assessment and must be submitted manually with valid supporting documents.
3. Travel Allowances or Company Car? There’s More to Declare
If you receive a travel allowance or use a company vehicle for work, you could be eligible to deduct business travel expenses. But here’s the catch:
👉 SARS won’t calculate these for you — even though they could significantly reduce your tax liability. Log those kilometres and submit them yourself!
4. Using Personal Devices for Work? Claim Wear and Tear
Your laptop, phone, or tablet could be working overtime — and so can your tax return. SARS allows a Section 11(e) wear-and-tear allowance, but it’s not included in your auto-assessment.
💡 Tip: Keep records of purchase dates and values, then submit your claim manually to benefit from this deduction.
5. Do You Have Side Hustles or Freelance Income?
SARS only knows what’s officially reported. If you earn money through freelancing, rentals, or any side gigs, it won’t show up in your auto-assessment.
📌 You’re legally required to disclose all additional income. Failing to do so could trigger audits, penalties, and interest — even years later.
6. Unclaimed Out-of-Pocket Medical Expenses
Got medical bills that weren’t covered by your aid? You may qualify for a Section 6B medical credit, which reduces your tax bill.
🛑 But these expenses are not automatically included, so you’ll need to submit the receipts and claims manually.
7. Even if You’re Getting a Refund — Still Review Carefully
It’s tempting to click accept when a refund is on the line. But don’t fall into the trap.
📣 Know this: If the assessment is incorrect — even if it benefits you — and you knowingly accept it, you’re still liable for penalties of up to 200% and interest.
👉 Accepting the refund without full disclosure could haunt you later, especially during a SARS audit.
8. Important Deadline: 20 October 2025
If your auto-assessment is incomplete or incorrect, you must file an accurate return manually before the deadline. Waiting too long or failing to submit can lead to serious legal and financial consequences.
Final Thought: Convenience vs Accuracy
Auto-assessments may save time, but they rarely paint your complete financial picture. When in doubt, consult a tax practitioner to ensure everything is above board and you’re not overpaying (or under-declaring).
🔎 Bottom line: Check every detail before accepting. Because when it comes to taxes, the devil is in the (overlooked) deductions.
