Tax Obligations for Sole Proprietors in South Africa
Last updated: 2026-03-19
Sole proprietors in South Africa are taxed on their total worldwide income at the individual progressive tax rate, which ranges from 18% to 45%. Your business profits are not taxed separately — they are added to any other income you earn (salary, rent, interest) and taxed together on your ITR12 return.
This is fundamentally different from a PTY Ltd, where the company pays a flat 27% corporate tax rate. As a sole proprietor, if your total taxable income is below R95,750 (under 65), you pay no tax at all. But if your business is profitable and pushes your total income into higher brackets, you could be paying 36% or more on your marginal income.
An important alternative for small sole proprietors is the turnover tax system. If your qualifying turnover is below R1 million per year, you can elect for turnover tax, which applies a simplified sliding scale from 0% (up to R335,000) to 3% on turnover rather than profit. This eliminates the need for detailed expense tracking and provisional tax submissions, making compliance significantly simpler.
