SARS and Small Business: What Every South African SMB Owner Needs to Know About Tax
A plain-English guide to SARS and small business tax in South Africa — VAT registration, provisional tax, turnover tax, and the records every SMB owner must keep.
Tax is the area most business owners learn about the hard way
SARS doesn't accept "I didn't know" as a reason for non-compliance. Penalties, interest, and — in serious cases — criminal prosecution are all on the table. The good news: the basics are not complicated once they're explained clearly.
The four taxes that matter most for South African SMBs
1. Income tax
If your business makes a profit, you pay tax on it. The rate depends on your business structure:
- Sole proprietor / freelancer: Your business income is added to your personal income and taxed at your marginal rate
- Private company (Pty Ltd): Corporate tax rate is 27% on taxable income (as of 2024)
- Small Business Corporation (SBC): If you qualify, reduced rates apply — 0% on the first R95,750, 7% from R95,750 to R365,000, and so on
2. Provisional tax
This is how SARS collects income tax during the year rather than as a lump sum at year-end. You submit two provisional tax returns per year (plus an optional third) and pay estimates of your annual tax liability. Missing these deadlines attracts automatic penalties.
3. VAT
You must register for VAT once your taxable turnover exceeds R1 million in any 12-month period. You may register voluntarily from R50,000. Once registered, you add 15% VAT to invoices, collect it from clients, and pay it to SARS monthly or bi-monthly.
4. PAYE (Pay As You Earn)
If you have employees, you're responsible for deducting PAYE from their salaries and paying it to SARS monthly, along with UIF and SDL contributions.
The records every SMB must keep
SARS requires you to keep financial records for a minimum of 5 years. This includes: all invoices issued and received, bank statements, contracts, payroll records, and VAT records.
The most common SMB tax mistakes
- Not separating business and personal finances — makes record-keeping a nightmare and draws SARS scrutiny
- Forgetting provisional tax deadlines — the penalties are automatic and non-negotiable
- Not registering for VAT when required — SARS will back-calculate and you'll owe the VAT you should have charged, out of your own pocket
- Claiming personal expenses as business expenses — legitimate deductions are allowed, but personal expenses are not
