What Is a Small Business Corporation (SBC) for Tax?
Quick Answer
What Is a Small Business Corporation (SBC) for Tax?
A Small Business Corporation (SBC) is a company that meets SARS‘s qualifying rules – gross income of R20 million or less, natural-person shareholders, not a personal service provider – and in exchange pays reduced tax: 0% up to R99,000 profit, then 7%, 21% and 27% (2026/27).
What this means in plain language
SBC is not a registration – it is a tax status SARS applies automatically at assessment if your company qualifies. The savings are real: at R400,000 profit, an SBC pays about R25,970 instead of R108,000 at the flat 27% rate.
The disqualifiers catch people: investment income above 20% of receipts, “personal service” income, or shareholders holding shares in other companies can all break qualification. Try the SBC tax calculator.
Who this applies to
- Trading companies with gross income up to R20 million
- Owner-managed companies wanting lower company tax rates
Step by step
- Check gross income is R20 million or less for the year.
- Confirm all shareholders are natural persons who hold no shares in other private companies (with limited exceptions).
- Confirm no more than 20% of receipts are investment income, and the company is not a personal service provider.
- Tick the SBC question on the ITR14 and claim the reduced rates at assessment.
What it costs
| Item | Cost / detail |
|---|---|
| SBC rates 2026/27 | 0% to R99,000 | 7% to R365,000 | R18,620 + 21% to R550,000 | R57,470 + 27% above |
| Claiming SBC status | Free – applied on the ITR14 |
Common mistakes to avoid
- Assuming all small companies qualify – the “personal service provider” and investment-income tests knock many out.
- Directors holding shares in several private companies – that alone can disqualify the SBC.
- Confusing SBC with turnover tax – SBC taxes profit at reduced rates; turnover tax taxes sales.
A South African example
A Port Alfred boat-repair company earns R900,000 profit. All tests pass, so SBC rates apply: tax of about R133,470 instead of R243,000 at the flat rate – a R109,530 saving in one year.
