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 R2.3 million per year, you can elect for turnover tax, which applies a simplified sliding scale from 0% (up to R600,000) to 3% on turnover rather than profit. This eliminates the need for detailed expense tracking and provisional tax submissions, making compliance significantly simpler.

Frequently Asked Questions

Should a sole proprietor choose turnover tax or normal income tax?
Turnover tax is simpler but not always cheaper. It taxes turnover (revenue) rather than profit, so if your business has high expenses (low margins), normal income tax may result in lower tax. Turnover tax is best for service-based businesses with few deductible expenses and turnover under R2.3 million.
Does a sole proprietor pay Capital Gains Tax?
Yes. When you sell business assets (equipment, property), any capital gain is included in your taxable income at a 40% inclusion rate. Individuals also receive an annual CGT exclusion of R50,000. The primary residence exclusion of R2 million applies to personal property, not business property.
Can a sole proprietor claim travel expenses?
Yes. You can claim actual business travel expenses or use the SARS fixed-cost travel allowance method. Keep a logbook recording business vs. personal kilometres. SARS publishes deemed cost tables annually based on vehicle value.
