How SBC tax qualification works
The Small Business Corporation regime can drop your company tax bill sharply — but the qualifying rules are strict, re-tested every year, and missed in practice more often than you'd expect.
Why it matters
Standard company tax in South Africa is a flat 27% on taxable profit. A Small Business Corporation (SBC) uses graduated rates instead, starting at 0% below R99,000 and climbing to 27% only above R550,000. On a R500,000 profit, the difference is about R88,000 in tax saved per year — money that stays in the business. But SARS only grants SBC status to companies that meet every qualification every single year.
The six qualification tests
To qualify as an SBC under section 12E of the Income Tax Act, your company must tick all six boxes for the year:
- Legal form: close corporation, private company, or co-operative. Not a public company, not a trust.
- Shareholders: only natural persons (individuals). No shareholder may be a company, trust, or other entity at any point during the year.
- No other shareholdings: none of your shareholders may hold shares or interests in any other company or close corporation (with minor exemptions for listed shares, dormant companies, and body corporates). In practice, this is the test most often missed.
- Turnover ceiling: gross income (before deductions) must not exceed R20 million for the year.
- Income mix: investment income and personal-service income together must not exceed 20% of total receipts and accruals. "Investment income" here includes rental, interest, dividends, annuities, royalties. "Personal service" income includes activities like legal, accounting, engineering, broadcasting, consulting — unless the company employs three or more full-time, unrelated employees engaged in that service.
- Not a labour broker or personal-service provider: the company must not be classified as either of these.
What catches people out
Two things, usually:
Other company interests. If a shareholder also owns even one share in another (non-listed, non-dormant) company, the whole company fails the SBC test — for the entire year. Many small-business owners set up multiple companies without realising each additional shareholding disqualifies the primary trading company from SBC. The fix is to consolidate shareholdings or restructure, which needs proper tax advice.
Personal-service creep. A consulting company with one shareholder doing most of the billable work is probably a "personal service provider" in SARS's eyes, taxed at 27% (or worse — individual marginal rates if the arrangement is caught by section 8C or the reportable arrangements rules). To step outside the personal-service net, you typically need at least three full-time unrelated employees actively doing the work.
How the rates apply
If you qualify, SBC brackets for the 2026/27 year of assessment are:
- 0 – R99,000: 0%
- R99,001 – R365,000: 7% on the portion above R99,000
- R365,001 – R550,000: R18,620 + 21% on the portion above R365,000
- R550,001 and above: R57,470 + 27% on the portion above R550,000

Practical tip
Re-test SBC status every year before you file ITR14, because the tests apply for each full year of assessment — not just when you incorporate. A change in shareholders, a windfall rental cheque, or picking up a second company mid-year can push you over a line you didn't know you were near.
