Trade as a sole proprietor while your profits are modest, you have no employees and your work carries little risk of a claim. Register a (Pty) Ltd once you take on staff, sign contracts with real liability attached, own assets worth protecting, or deal with clients who will only contract with a company. The single most important difference is not tax — it is that a sole proprietor is personally liable for every debt the business incurs.
Most South African businesses start as sole proprietors and should. The question is not which is better in the abstract, but which is right for where you are now.
TL;DR
| Sole proprietor | (Pty) Ltd | |
|---|---|---|
| Legal status | You are the business | Separate legal person |
| Liability | Unlimited and personal | Limited to what you put in |
| Tax | Your personal rates, 18%–45% | 27%, or SBC rates from 0% |
| Registration | None required | CIPC — around R175 in fees |
| Annual compliance | Your ITR12 | Annual return, BO filing, AFS, ITR14, provisional tax |
| Running cost | Very low | R2,000–R6,000+ a year minimum |
| Credibility | Lower with corporates | Higher |
| Can you sell it? | Assets only | Shares — much cleaner |
The difference that matters most: liability
Everything else is a detail next to this.
As a sole proprietor, there is no legal separation between you and the business. Business debts are your debts. If the business is sued, you are sued. If it cannot pay, creditors can pursue your house, your car and your personal savings.
A (Pty) Ltd is a separate legal person. It contracts in its own name, owes its own debts, and is sued in its own name. Your exposure is generally limited to what you have invested.
Four things that pierce that protection anyway:
Personal surety. Banks and landlords routinely require directors to sign surety. Where you have, you are personally on the hook regardless of the company.
Unpaid PAYE and VAT. Personal liability provisions exist for certain withheld taxes.
Reckless trading. Directors who trade recklessly or fraudulently can be held personally liable.
Personal negligence. Where you personally caused the harm, incorporation is not a shield.
Which risks matter to you? A copywriter working from home has limited claim exposure. An electrician, a food business, a transport operator or anyone with employees has considerably more.
The tax comparison
Sole proprietor
Business profit is added to your other income and taxed at personal rates for 2026/27:
| Taxable income | Rate |
|---|---|
| R0 – R245,100 | 18% |
| R245,101 – R383,100 | R44,118 + 26% |
| R383,101 – R530,200 | R79,998 + 31% |
| R530,201 – R695,800 | R125,599 + 36% |
| R695,801 – R887,000 | R185,215 + 39% |
| R887,001 – R1,878,600 | R259,783 + 41% |
| R1,878,601 + | R666,339 + 45% |
You get the primary rebate of R17,820 and pay nothing below R99,000.
(Pty) Ltd
27% flat, or the Small Business Corporation sliding scale if you qualify — 0% on the first R99,000, then 7%, 21% and 27%.
Then 20% dividends tax when you take the profit out, giving a combined 41.6% on distributed profits for a standard company.
Where the crossover sits
At low profit the sole proprietor wins comfortably. R150,000 of profit costs a sole proprietor roughly R9,180 after the rebate; a non-SBC company pays R40,500 before you have taken anything out.
At higher profit the picture shifts, but less dramatically than people assume — because a company owner still has to extract the money, and salary is taxed at the same personal rates. The genuine tax advantages of a company are the SBC rates, the ability to retain profit in the company at 27% rather than 45%, and the flexibility to blend salary and dividends.
We work the numbers properly in at what profit does a company beat a sole proprietor on tax.
Do not incorporate for tax alone at modest profit levels. The compliance cost frequently exceeds the saving.
What each actually costs to run
Sole proprietor
No registration fee
No CIPC filings
One annual tax return, plus provisional tax if applicable
Bookkeeping — but simpler
Realistic annual cost: R3,000 – R15,000
(Pty) Ltd
CIPC registration, around R175 in fees
CIPC annual return every year
Beneficial ownership filing every year
Annual financial statements within six months of year end
ITR14 plus two provisional returns
Realistic annual cost: R12,000 – R40,000+
The gap is real, and for a business making R200,000 a year it matters.
The four triggers to incorporate
Forget the tax question for a moment. These are the signals that actually decide it.
1. You are hiring. Employing people creates liability — labour claims, injury on duty, unpaid wages. It also creates PAYE and UIF obligations that expose you personally as a sole proprietor.
2. You are signing contracts with real consequences. A supply agreement with penalties, a lease with a long term, a project where failure means a claim. Sign those in your own name and you carry them personally.
3. Your clients require it. Corporates, government and many larger customers will only contract with a registered company. Tenders effectively require it — CSD registration, B-BBEE affidavits and tax clearance all assume an entity.
4. You have assets worth protecting. A house, savings, a spouse's assets in a joint estate. The more you have outside the business, the more the separation is worth.
A fifth, quieter one: you intend to sell one day. Selling a company means selling shares — clean, well understood and usually more tax-efficient. Selling a sole proprietorship means selling a collection of assets and renegotiating every contract and supplier relationship.
What does not decide it
"A company looks more professional." Sometimes true with corporate buyers. Rarely worth R20,000 a year on its own if none of the four triggers apply.
"I need a company to have a business bank account." You do not. Banks offer business accounts to sole proprietors. You should absolutely have a separate account either way — mixing business and personal money is the most expensive bookkeeping habit there is.
"I need to be a company to register for VAT." You do not. A sole proprietor can register for VAT, and must once taxable supplies exceed R2.3 million in any consecutive 12 months. See the VAT registration threshold.
"I need a company to invoice clients." You do not. A sole proprietor invoices using their own name and ID number.
Switching later
You are not locked in. Many businesses start as sole proprietors and incorporate once a trigger arrives, which is usually the sensible sequence.
What the switch involves: registering the company, transferring assets, novating contracts and supplier accounts, moving the bank account, registering the company with SARS, and closing off the sole proprietor position.
Watch two things: transferring assets can trigger capital gains tax, and if you are VAT registered as a sole proprietor the change of entity has VAT consequences. Get both reviewed before you move.
The cost of switching is modest. The cost of not incorporating when you should have is not — because liability is retrospective and no amount of later restructuring undoes a claim that has already arisen.
Frequently asked questions
Should I be a sole proprietor or a Pty Ltd in South Africa? Stay a sole proprietor while profits are modest, you have no employees and your work carries little claim risk. Incorporate once you hire staff, sign contracts with real liability, own assets worth protecting, or deal with clients who require a company.
Is a Pty Ltd more tax-efficient than a sole proprietor? Not automatically. At low profit levels a sole proprietor usually pays less, because of the primary rebate and the R99,000 threshold. A company becomes attractive at higher profits, particularly where it qualifies as a Small Business Corporation or where you want to retain profit in the business rather than draw it all out.
Am I personally liable as a sole proprietor? Yes, without limit. There is no legal separation between you and the business, so business debts are your debts and creditors can pursue your personal assets.
Does a Pty Ltd fully protect my personal assets? Largely, but not absolutely. Personal surety signed for a bank or landlord, unpaid PAYE and VAT, reckless trading, and your own personal negligence can all create personal liability despite incorporation.
Do I need a company to register for VAT? No. A sole proprietor can register for VAT voluntarily and must register once taxable supplies exceed R2.3 million in any consecutive 12-month period.
Can a sole proprietor open a business bank account? Yes. Banks offer business accounts to sole proprietors. Keeping business and personal money separate is worth doing regardless of structure.
How much does it cost to run a Pty Ltd in South Africa? Realistically R12,000 to R40,000 or more a year, covering the CIPC annual return, beneficial ownership filing, annual financial statements, the ITR14 and two provisional tax returns, plus bookkeeping. A sole proprietor typically runs at R3,000 to R15,000.
Can I change from a sole proprietor to a company later? Yes, and many businesses do. It involves registering the company, transferring assets, novating contracts, moving banking and registering with SARS. Transferring assets can trigger capital gains tax, and an existing VAT registration has consequences on the change, so both should be reviewed first.
Get the timing right
The mistake that costs money is not choosing wrong at the start — it is staying a sole proprietor past the point where one of the four triggers arrived, because liability does not wait for you to restructure.
