Tax and Compliance
Company Structures and Tax in South Africa
Choosing a business structure is as much a tax decision as a legal one. The structure you choose determines what rate applies to your profits, how you extract money from the business, what your ongoing compliance obligations are, and how much you ultimately keep. Most people frame this as a legal question. The tax question is at least as important.
Getting this wrong at the start is not fatal. Structures can be changed, and many South African businesses convert from sole proprietor to PTY Ltd once they reach a meaningful profit level. But converting later is administratively complex and sometimes triggers tax consequences, so it is worth thinking through the decision properly before you register anything.
The Main Structures and How They Are Taxed
Sole Proprietorship
A sole proprietor has no legal separation between the owner and the business. The business has no existence of its own. You trade under your own name or a trading name, there is no CIPC registration, and business income is declared on your personal ITR12 return alongside any other income you earn.
Tax is applied at individual marginal rates, which range from 18% at the lowest bracket to 45% above R1.8 million. At low income levels this can be more efficient than a company because the personal tax-free threshold (R99 000 for under-65s) exempts the first portion, and the rebates that apply to individuals do not apply to companies.
The structural problem with a sole proprietorship is that there is no mechanism to retain profits in the business at a lower tax rate. Every rand of profit is taxed as personal income in the year it is earned, regardless of whether you draw it out or reinvest it. As profitability grows, so does your marginal rate, and eventually you are taxed at 45% on every additional rand.
The other issue is liability. As a sole proprietor, there is no legal barrier between your business and your personal assets. A client dispute, a contract claim, or a supplier debt can reach your home, your vehicle, and your savings. That risk is worth weighing seriously before deciding to remain unincorporated.
When it works: Early stage, low revenue, low risk profile, solo service work where the compliance cost of a company is not justified by the tax saving.
Partnership
A partnership involves two or more people running a business together. Like a sole proprietorship, it is not a separate legal entity. It is not a taxpayer in its own right. Each partner is taxed individually on their share of the partnership's profits, at their personal marginal rate.
The significant risk in a partnership is joint and several liability. You are personally responsible not just for your own business decisions but potentially for your partner's as well. This is why most professional practices that start as partnerships eventually incorporate.
Partnerships are common among attorneys, accountants, and medical practitioners, largely for historical and regulatory reasons. For most other business types, a PTY Ltd with multiple shareholders is a cleaner structure that achieves the same co-ownership goal with better legal protection.
When it works: Professional practices where regulation or convention drives the structure, or very early-stage ventures where two founders are testing an idea before committing to incorporation.
PTY Ltd (Private Company)
A PTY Ltd is a separate legal entity registered with the Companies and Intellectual Property Commission (CIPC). The company can own assets, enter contracts, and incur debts in its own name. Your personal assets are not exposed to business creditors as long as you have not signed personal sureties (which banks will typically require for debt).
The company pays corporate income tax at 27% of taxable profit. That is a flat rate from the first rand of profit, with no free threshold. You then pay personal income tax on whatever salary you draw from the company, and 20% dividends tax on any profit distributed to you as a shareholder. These are two separate tax events on the same underlying profit.
The 27% rate is lower than the 45% top marginal personal rate, which is where the tax advantage of a PTY Ltd lies at higher income levels. The ability to retain profits in the company and pay tax at 27% rather than taking them out as personal income creates a genuine deferral benefit for reinvestment. A business owner who needs R500 000 back in the business for growth can leave it there and pay 27% tax, rather than extracting it as income and paying 41% or 45%.
The compliance obligations are real: annual CIPC returns (due within 30 business days of your anniversary date), annual financial statements, provisional tax submissions, and an ITR14 return within 12 months of your financial year-end. These have fixed deadlines and automatic penalties for non-compliance. Missing your CIPC annual return can trigger late penalties and eventually deregistration, which is slow and administratively painful to reverse.
When it works: Growing businesses above meaningful profit levels, any business with liability exposure, businesses pursuing corporate clients or government tenders, and any situation where you have co-founders who need defined shareholding.
Small Business Corporation (SBC)
If your PTY Ltd qualifies as an SBC, significantly better tax rates apply instead of the flat 27%. The rates for 2025/26 are:
- 0% on the first R95 750 of taxable income
- 7% on R95 750 to R365 000
- 21% on R365 000 to R550 000
- 27% above R550 000
To qualify, all shareholders must be natural persons (no company shareholders), gross income must not exceed R20 million, no shareholder may hold shares in another private company (with limited exceptions), and no more than 20% of income may come from investment income or personal services.
The saving is material. A qualifying SBC with R500 000 of taxable profit pays roughly R47 000 in tax. The same company at the standard 27% rate would pay R135 000. That is an R88 000 difference in a single year. SBC status is tested annually and can be lost if shareholder circumstances change, so it requires ongoing monitoring.
SBCs also qualify for accelerated depreciation on assets, which can further reduce taxable profit in early years.
Turnover Tax
For micro-businesses with annual turnover below R2.3 million, Turnover Tax is an elective simplified regime that replaces normal income tax, provisional tax, and capital gains tax with a levy on revenue at rates between 0% and 3%. The main appeal is reduced compliance cost. The main drawback is that you pay on revenue regardless of whether the business made a profit. It is worth modelling against your actual margins before electing it.
The Tax Comparison That Actually Matters
The original question most founders ask is: "Which structure pays less tax?" The honest answer is that it depends on profit level, how much you need to draw personally, and whether you qualify for SBC rates.
At low profit levels (under R200 000), a sole proprietor often pays less tax in total because the personal tax-free threshold and rebates apply. A company pays 27% from rand one.
At moderate profit levels (R300 000 to R550 000), a qualifying SBC typically wins decisively because the progressive rates and zero band produce a very low effective rate, well below what a sole proprietor in those brackets would pay.
At higher profit levels (above R550 000), the PTY Ltd advantage depends on how much you extract personally. A sole proprietor taking R1 million of profit pays personal income tax across the full amount, reaching marginal rates of 41% to 45% on the upper portion. A company owner who draws a moderate salary and retains the rest in the company pays 27% on retained profit, personal income tax on the salary, and defers the dividends tax until profits are distributed. Over multiple years, this deferral effect compounds.
The practical caveat: the moment you extract profits from the company as dividends, you pay 20% dividends tax on the distribution. The combined effective rate on company profit fully extracted as dividends is roughly 41.6% (27% corporate tax, then 20% dividends tax on the after-tax amount). That is close to the personal marginal rate at R1 million income. The PTY Ltd advantage is therefore strongest when you can leave meaningful profit in the business for reinvestment, rather than extracting everything each year.
What the Compliance Difference Actually Costs
The original article correctly notes that a sole proprietorship has less compliance than a PTY Ltd. It is worth being specific about what that difference involves.
A sole proprietor files one personal return per year. There is no CIPC, no annual financial statements, no separate bank account requirement (though one is strongly advisable in practice), and no ITR14. Provisional tax applies if income is above the tax threshold.
A PTY Ltd requires CIPC registration (once-off), an annual CIPC return, a separate bank account, annual financial statements (which can be internally compiled at small scale but must meet minimum standards), an ITR14 within 12 months of year-end, and two provisional tax returns per year. If you have employees, add monthly EMP201 submissions and biannual EMP501 reconciliations.
For a one-person business, the additional compliance cost of a PTY Ltd is typically R5 000 to R15 000 per year in accountant fees, depending on complexity. That cost needs to be weighed against the tax saving. Below approximately R400 000 to R500 000 in annual profit, the tax saving often does not justify the additional cost and admin unless liability protection is the primary driver.
Decisions That Are Harder to Reverse Than They Appear
Converting from sole proprietor to PTY Ltd requires transferring contracts and potentially renegotiating them, moving assets into the new entity (which may trigger CGT or transfer duty depending on the asset), and notifying clients and suppliers. It is manageable but takes time.
The shareholder structure of a PTY Ltd matters from day one. Adding a shareholder later requires a formal share transfer and can affect SBC eligibility if the new shareholder holds shares elsewhere. Removing a shareholder has its own tax implications. If you have co-founders, agree the shareholding structure before registering.
If a shareholder later takes a small stake in another private company for unrelated reasons, your SBC status may be at risk. This is a common issue and worth understanding before it happens.
The Question to Answer Before You Register
The right structure depends on your expected income, your liability exposure, whether you have co-founders, and where you want the business to be in three years. It is a decision that involves both an accountant (for the tax angle) and an attorney (for the legal angle). The professional fees for that combined consultation are typically R2 000 to R5 000 and almost always justify themselves.
The one thing not to do is choose a structure based on what seems easiest to register today without modelling what the tax looks like when the business is profitable. That modelling takes 30 minutes with an accountant and can save years of inefficiency.
