Discover the most common tax mistakes South Africans make when filing SARS returns.

Filing your South African personal income tax return can feel overwhelming, especially if you’re juggling multiple income streams like freelance gigs, side businesses, or even cryptocurrency investments. But did you know that a few common mistakes could be costing you thousands of rands in tax refunds?

At CH Consulting, we’ve seen it all. Here are the 7 most frequent slip-ups South Africans make when filing their taxes, and how to avoid them to maximise your refund.

1. Incorrect or Incomplete Information

Simple errors like typos in your ID number, banking details, or income figures can delay or even jeopardize your tax refund.

Tip: We always double-check your details on SARS eFiling before submitting your tax returns.

2. Not Declaring Cryptocurrency Earnings

Crypto gains are taxable in South Africa! Many assume SARS isn’t tracking crypto profits, but this is a myth. Failing to declare your crypto earnings can lead to audits and penalties.

3. Missing Out on Allowable Deductions

Most taxpayers forget to claim deductions they’re entitled to, such as:

  • Gas fees for crypto
  • Retirement annuity contributions
  • Medical aid expenses
  • Home office costs
  • Donations to registered charities

Tip: Keep accurate records of all receipts year-round.

4. Incorrectly Claiming Expenses

Claiming unapproved or non-business-related expenses is a red flag for SARS and could trigger an audit. Our team will send you a simple template to help you know exactly what you can and cannot claim for.

5. Forgetting to File Provisional Tax

If you earn income outside of traditional employment, like consulting, freelancing, or crypto, you might need to file provisional tax twice a year.

Missing deadlines leads to penalties and interest. Once you have those, forget about getting a refund until they’re sorted out.

6. Underreporting Side Hustle or Freelance Income

With the rise of side hustles and online work, many South Africans forget that all income sources, even PayPal and crypto wallets, must be declared.

7. Submitting Late

Late submissions = automatic penalties. Don’t leave your filing to the last day! All our clients are notified well in advance to avoid these penalties and maintain compliance.
