Three South African tax regimes compete for the same small company, and the wrong choice is expensive in both directions. Small business corporation tax (the SBC rules), turnover tax for registered micro businesses, and the ordinary company rate each carry different qualifying tests, a different admin load and a different break-even point. Most owner-managers only find out which one they should have been on when the assessment lands.
This guide sets out who qualifies for each, what each one really costs once you count the paperwork, and the handful of questions that decide it in practice.
The three regimes in one view
| Turnover tax | Small business corporation | Standard company | |
|---|---|---|---|
| What is taxed | Qualifying turnover, before expenses | Taxable income, on a graduated scale | Taxable income, at the flat company rate |
| Who may use it | Sole proprietors, partnerships, close corporations and companies below a turnover ceiling | Private companies, close corporations and co-operatives that pass every test | Any company, with no qualifying conditions |
| Shareholder test | Holders must be natural persons, with restrictions on other interests | All holders natural persons all year, and no shares held in other companies save narrow exceptions | No restriction |
| Income mix test | Professional service income is limited | Caps on investment income and personal service income, and no personal service providers | No restriction |
| Deductions and allowances | Expenses are not deducted at all | Normal deductions plus accelerated write-offs on qualifying assets | Normal deductions and wear and tear allowances |
| Admin load | Lightest: simplified returns and interim payments | Full ITR14 plus provisional tax | Full ITR14 plus provisional tax |
| Usually suits | Tiny, profitable, low cost businesses | Growing trading, service and manufacturing companies owned by individuals | Companies with a corporate shareholder, a group, or income the SBC tests exclude |
Who actually qualifies for turnover tax
Turnover tax is an elective regime for registered micro businesses. Instead of computing taxable income, you apply a rate to qualifying turnover. That is the whole appeal: no expense analysis, no wear and tear schedules, and a much shorter return.
The qualifying conditions are narrower than most owners expect. Turnover must sit below the ceiling for the year, and the ceiling is tested on the full year, so a strong final quarter can push you out retrospectively. Holders of the business must be natural persons, and there are restrictions on holding interests in other entities. Income from professional services is capped, which excludes a large share of the consultants who would otherwise be the natural market for it.
- It taxes receipts, not profit. In a year where you lose money, you still pay.
- It ignores your cost base. A trading business buying stock at a thin margin is usually worse off than it would be on normal rules.
- Capital receipts and dividends are treated differently. Some relief applies to registered micro businesses, which is genuinely useful on a business sale.
- Exit is restricted. Leaving the regime, voluntarily or because you breached the ceiling, has consequences for when you may re-enter.
Who qualifies as a small business corporation
The SBC rules are not a separate tax. They are a concession inside the normal company tax system, giving qualifying companies a graduated rate scale with a nil band at the bottom, plus accelerated write-offs on qualifying assets, notably plant and machinery brought into use in a process of manufacture.
There is no application form. You claim the treatment in the company income tax return by answering the qualifying questions, and SARS applies the scale if the answers pass. That self-assessment is exactly why the claim gets reversed so often: nobody re-checks the tests when the shareholder register changes.
- 1Entity type. A private company, a close corporation or a co-operative. A trust or a sole proprietorship cannot qualify.
- 2Shareholders. Every holder must be a natural person for the entire year of assessment, and no holder may hold shares in another company, other than the narrow exceptions the Act lists such as listed shares and certain dormant entities.
- 3Gross income ceiling. Gross income for the year must sit below the prescribed limit.
- 4Income mix. Not more than the prescribed proportion of receipts may come from investment income and personal services combined, and the company must not be a personal service provider.

The standard company rate, and why it is often still right
The ordinary company rate is a flat rate on taxable income, with dividends tax withheld when profits are distributed to individual shareholders. It has no qualifying tests, no annual re-check and no cliff edge. For a business with a holding company, a trust shareholder, an offshore investor or a second trading entity, it is not a choice at all: the SBC tests are simply failed.
It is also the regime that lets you plan properly. Deductions, assessed losses, wear and tear allowances and the timing of asset purchases all work normally, and the extraction question, salary versus dividend versus loan account, is where most of the real saving sits for an owner-manager.
How to choose: the questions that decide it
- What is your gross margin? Thin margins argue hard against turnover tax, because tax is charged before your costs.
- Does anyone hold shares in another company? If yes, the SBC rules are closed to you until that changes.
- Is your income mostly personal services? Both concessions restrict this, and the personal service provider rules can be more punishing than either.
- How volatile is turnover? A business that oscillates around the ceiling will spend more on regime changes than it saves.
- What is your admin capacity? If you are already producing monthly management accounts, the admin saving of turnover tax is worth almost nothing to you.
- Are you buying manufacturing plant? The accelerated SBC write-off can outweigh the rate difference in the year of purchase.
Owners chase the headline rate and ignore the tests. The regime you qualify for in March is not always the one you qualify for in February, and the cost of finding that out late is interest, not just tax.

Switching regimes, and what it costs
Moving between regimes is not free. Leaving turnover tax triggers rules about how soon you may return. Losing SBC status mid-life means the graduated scale falls away for the whole year of assessment, not from the date of the change, so a shareholding restructure in month eleven can cost you the concession for all twelve months. Plan the change into the year, not out of it.
Whichever regime applies, the provisional tax obligation does not go away. Estimates still have to be reasonable, and the provisional tax deadlines still bind you.
How Synergy helps
Our tax services start with the regime question, because it is cheap to get right at the beginning and expensive to fix afterwards. We test the SBC conditions against your actual shareholder register each year, model the alternatives on your own numbers, and prepare the returns that follow. Where the answer changes the way you draw money from the business, we work through the extraction plan with you rather than leaving it to year-end.
