Tax season deadline is around the corner, and for many small business owners, it can feel like a stressful time filled with paperwork, reconciliations, and deadlines. But most of the pressure comes from small mistakes that are completely avoidable with the right preparation.
At nhb.business, we see these same issues pop up every year. They can easily delay refunds, trigger penalties, or create unnecessary admin. Below are the most common tax mistakes South African businesses make, and how to avoid them.
1. Not Reconciling Accounts Accurately
Your bank accounts, credit cards, and accounting records should always align before submitting returns. Even a small mismatch can cause discrepancies in your financial statements and create complications with SARS.
How to fix it:
Reconcile every account monthly, not only at year-end. Make sure your accounting software matches your bank statements and keep digital records of all supporting documents. This applies to all business accounts – investments, credit cards or even your pettycash.
2. Forgetting to Update SARS Banking Details
SARS has strengthened its banking verification process to combat fraud. If your business banking details are outdated or incorrect, your refund can be delayed for weeks.
How to fix it:
Log into your eFiling profile and check that your registered bank account is active, correct, and verified. Always use official SARS channels for updates and avoid making changes during peak filing periods.
3. Misclassifying Income and Expenses
A common error we see is miscategorising business income or personal expenses, which can distort your financial results and affect your tax liability.
How to fix it:
Maintain clear separation between business and personal accounts. Keep a consistent chart of accounts and review expense categories with your accountant to ensure compliance with SARS reporting standards.
4. Missing Supporting Documentation
Even if your financials are accurate, missing invoices, slips, or proof of payment can cause major issues during audits. SARS requires you to retain records for at least five years.
How to fix it:
Digitise and store all documents in a secure cloud folder. Use accounting software that automatically attaches receipts and invoices to transactions to streamline recordkeeping.
5. Ignoring Provisional Tax Deadlines
Small business owners often underestimate their provisional tax obligations, leading to underpayment penalties or cash flow issues later.
How to fix it:
Plan ahead for the two provisional tax periods (August and February). Review your projections early and make payments on time to avoid penalties and last-minute stress.
6. Overlooking Changes in Tax Legislation
SARS frequently updates rules, forms, and requirements. Missing these updates can mean filing on outdated forms or missing new declarations such as foreign income or trust disclosures.
How to fix it:
Stay informed through trusted accounting professionals or the official SARS website. Partner with an accounting firm that keeps track of regulatory changes and ensures your submissions remain compliant.
7. Leaving Tax Preparation Until the Last Minute
Rushed submissions lead to avoidable errors, missed claims, and unnecessary panic.
How to fix it:
Treat tax as an ongoing process, not a once-a-year task. Schedule regular reviews with your accountant to keep everything up to date throughout the year.
