What Is a Small Business Corporation?
A Small Business Corporation (SBC) is a company or close corporation that meets specific criteria under Section 12E of the Income Tax Act. SBCs are taxed at preferential rates designed to support small business growth.
SBC Tax Rates for 2025/2026
| Taxable Income | Rate |
|---|---|
| R0 – R95,750 | 0% |
| R95,751 – R365,000 | 7% of amount above R95,750 |
| R365,001 – R550,000 | R18,848 + 21% of amount above R365,000 |
| Above R550,000 | R57,698 + 27% of amount above R550,000 |
Compare this to the standard corporate tax rate of 27% on all taxable income. For a company with R400,000 in taxable income:
- Standard rate: R400,000 × 27% = R108,000
- SBC rate: R18,848 + (R400,000 − R365,000) × 21% = R18,848 + R7,350 = R26,198
The saving is R81,802 — a compelling reason to ensure your business qualifies.
Qualifying Criteria for SBC Status
To qualify as an SBC, ALL of the following conditions must be met:
1. Gross Income Threshold
Annual gross income must not exceed R20 million in the year of assessment.
2. Shareholding / Membership
All shareholders or members must be natural persons (not companies or trusts). This is the most commonly violated criterion — many business owners hold shares through a family trust, which immediately disqualifies the company.
3. No Personal Service Company
The company must not be a personal service company — defined as a company where:
- More than 80% of income is from services rendered by a connected person (shareholder), AND
- The company does not employ three or more full-time employees (other than shareholders or connected persons)
4. No Investment Company
The company must not be an investment company — i.e., it cannot derive more than 20% of its income from investment income (interest, dividends, rental from immovable property).
5. Not a Labour Broker
The company must not be a labour broker.
6. Shareholding in Other Companies
Shareholders of the SBC must not hold shares in any other company (with limited exceptions for listed companies and certain holding structures).
Common Disqualification Errors
1. Trust as ShareholderThis is the most frequent disqualification. Many business owners are advised to hold shares through a family trust for estate planning purposes — but this immediately disqualifies the company from SBC status. The tax saving from SBC status often exceeds the estate planning benefit of the trust structure.
2. Investment Income Exceeding 20%If your company earns significant rental income or interest income, this can push investment income above the 20% threshold and disqualify SBC status.
3. Shareholder Holding Shares in Another CompanyIf a shareholder also holds shares in another private company (not a listed company), the SBC qualification is lost. This catches many entrepreneurs who have multiple business interests.
Turnover Tax: An Alternative for Very Small Businesses
For businesses with annual turnover below R1 million, the Turnover Tax system (also known as the Micro Business regime) may be even more advantageous than SBC status:
| Annual Turnover | Tax |
|---|---|
| R0 – R335,000 | 0% |
| R335,001 – R500,000 | 1% of amount above R335,000 |
| R500,001 – R750,000 | R1,650 + 2% of amount above R500,000 |
| R750,001 – R1,000,000 | R6,650 + 3% of amount above R750,000 |
Turnover Tax replaces income tax, VAT, CGT, and dividends tax — significantly simplifying compliance for very small businesses.
Structuring for SBC Qualification
If your business currently does not qualify for SBC status, a restructuring review may be worthwhile. Common interventions include:
- Moving shares from a trust to individual shareholders (with appropriate estate planning alternatives)
- Separating investment activities into a separate entity
- Ensuring the company has sufficient non-shareholder employees to avoid personal service company classification
