The three ways small businesses are taxed

1. Standard company tax — 27%

A normal (Pty) Ltd pays a flat 27% on taxable income, regardless of size.

2. Small Business Corporation (SBC) rates

If you qualify as an SBC (turnover under R20m, individuals-only shareholders, and other rules), you pay reduced graduated rates:

Taxable incomeRate
R0 – R99,0000%
R99,001 – R365,0007% of the amount above R99,000
R365,001 – R550,000R18,620 + 21%
R550,001 and aboveR57,470 + 27%

3. Turnover Tax

Micro-businesses with turnover up to R2.3 million can elect Turnover Tax, a simplified tax on turnover (not profit):

TurnoverRate
R0 – R600,0000%
R600,001 – R950,0001% above R600,000
R950,001 – R1,400,000R3,500 + 2%
R1,400,001 – R2,300,000R12,500 + 3%
