Introduction
When starting a business in South Africa, you must decide whether to operate as a sole proprietor or to form a private company (Pty Ltd). Both structures are recognised under the Companies Act, but they differ widely in liability protection, taxation and regulatory requirements. Many entrepreneurs start as sole proprietors because it’s cheap and easy, but as the business grows, a formal company structure can offer significant advantages. This article explains the key differences and helps you determine which option best fits your goals for 2025.
1. What is a sole proprietorship?
A sole proprietorship (or “sole trader”) is owned and operated by one natural person. The business has no existence separate from the owner – you receive all the profits, but you also assume all the debts and risks associated with it. The owner must include the business income in their tax return and pay income tax at individual rates. This structure requires minimal paperwork: you do not have to register the business with the Companies and Intellectual Property Commission (CIPC); you start trading under your own name or a trade name.
Pros
- Easy to start and end. It’s simple to establish and operate; there are few legal requirements, besides registering with SARS for tax purposes at SARS.
- Full control. As the sole owner, you make all decisions and receive all profits.
- Low compliance costs. There is no requirement to prepare audited financial statements or submit CIPC annual returns.
Cons
- Unlimited liability. Because the business is not a separate legal entity, your personal and business assets are treated as one; creditors can attach both your business property and personal property to settle debts.
- Limited access to capital. Raising funds is challenging because investors typically prefer formal companies; as a result, you are limited to what you can secure personally.
- Higher tax rates at high income levels. Business profits are taxed at personal income tax rates, which can be higher than the corporate rate once profits grow.
2. What is a private company (Pty Ltd)?
A private company is treated as a separate legal entity under South African law. It must be incorporated with the CIPC, have at least one shareholder and one director, and operate under a Memorandum of Incorporation (MOI). The company’s name must include “Proprietary Limited” or “Pty Ltd”. As a separate entity, it can own property, enter into contracts and sue or be sued in its own name.. Private companies are automatically registered with SARS and receive their own tax reference number.
Pros
- Limited liability. Shareholders’ assets are protected; their liability is limited to the value of their shares. This is crucial if the business operates in a high‑risk environment.
- Better access to funding. Companies can issue shares to raise capital and tend to appear more credible to banks and investors.
- Structured governance. Having a formal board and MOI provides clarity on decision‑making and succession.
- Potential tax advantages. Companies pay corporate income tax at a flat rate (28% in 2025), which can be lower than personal tax rates once profits exceed around R660 000.
Cons
- Higher compliance burden. A private company must file annual returns with the CIPC and may need to have its financial statements audited or independently reviewed. It must also file a yearly ITR14 tax return with SARS.
- Cost and complexity of set‑up. Incorporation requires drafting an MOI, appointing directors and paying registration fees.
- Restrictions on shares. Shares cannot be offered to the public; the MOI often restricts the transfer of shares.
3 Comparing liability and risk
The most significant difference between these structures is liability. A sole proprietor is personally liable for all debts and obligations; there is no separation between personal and business assets. Taking on loans or selling products that could result in claims exposes you to personal risk.
A private company, by contrast, is a separate legal entity with limited liability. Your risk is confined to the share capital you have invested.. Creditors cannot generally pursue your assets for company debts (unless you signed a personal surety). Limited liability makes a private company better suited for businesses with significant risk or where personal wealth needs to be protected.
4 Tax Differences
- Personal vs corporate tax rates. Sole proprietor income is taxed on a sliding scale along with your other income. At higher income levels, this can result in marginal tax rates above 30%. Private companies pay a flat corporate tax rate of 28%. For businesses earning above approximately R660,000 in taxable profit, incorporating can be a more tax-efficient option.
- VAT registration. Both structures must register for Value-Added Tax once their annual turnover exceeds R1 million. However, only a company can claim input VAT on expenses. Sole proprietors can register voluntarily, but a private company arrangement makes it easier to administer VAT.
- Small Business Corporation (SBC) relief. Private companies that meet specific requirements (all shareholders are natural persons, turnover < R20 million, etc.) qualify for SBC tax rates. These lower tax brackets make incorporation attractive for small businesses. Sole proprietors do not qualify for SBC relief.
- Provisional tax and filings. Sole proprietors pay provisional tax twice a year if the tax due exceeds R30,000 and file an annual income tax return. Private companies must submit a formal ITR14 return within 12 months of their financial year end, and may need to attach financial statements.
5 Regulatory and reporting requirements

| Governance | The owner makes decisions alone. | Must file annual returns with CIPC; may require audited financial statements; must file ITR14 and maintain formal accounting records. |
| Compliance | Minimal: register for income tax and possibly VAT; keep records. | The company name is reserved and protected through the CIPC. |
| Name protection | Trade names aren’t registered; someone else could use a similar name. | Limited; relies on personal credit and loans. |
| Cost and administration | Low set‑up and running costs. | Higher costs due to registration, accounting and auditing requirements. |
| Fundraising | Can issue shares (privately) and tends to be more attractive to investors and lenders. | Can issue shares (privately) and tends to be more attractive to investors and lenders. |
6 Which structure should you choose?
Choose a sole proprietorship if:
- You are freelancing, consulting or testing a small business idea with limited risk.
- You want to get started quickly and keep costs low.
- Your annual profits are modest, and you don’t anticipate needing outside investors.
Choose a private company (Pty Ltd) if:
- You need limited liability to protect your assets because your business is capital-intensive or high-risk.
- Your profits will exceed approximately R660,000 per year, making the corporate tax rate more attractive.
- You plan to bring in partners or investors and need to issue equity or formalise share ownership.
- You want to build a brand that exists independently of you and provides credibility with clients and suppliers.
7 Conclusion
The decision between operating as a sole proprietor or forming a private company depends on how much risk you’re willing to accept, your growth ambitions and the level of regulation you can manage. A sole proprietorship offers simplicity and control, but it also exposes your assets to business liabilities. A private company requires more paperwork and compliance but provides limited liability, potential tax advantages, and better access to capital. Assess your business’s projected income, risk profile and funding needs carefully; you can always start as a sole proprietor and incorporate later when your business scales.
