A subsidiary is registered exactly like any private company, with the parent company recorded as the shareholder. There is no separate CIPC process and no special form. The parent's board resolves to incorporate, the parent subscribes for the shares, and beneficial ownership looks through the parent to the natural persons behind it. The consequences worth planning for are the loss of Small Business Corporation status and a second, independent compliance calendar.
Registering it takes days. Deciding whether you should is the part worth spending time on.
The registration itself
1. The parent's board passes a resolution to incorporate a subsidiary, approving the name, the share subscription and who signs.
2. Reserve the name at CIPC in the usual way.
3. Register the company, with the parent company as subscriber and shareholder. You need the parent's registration documents alongside the usual director and identity documents.
4. Appoint the directors. They need not be the same people as the parent's directors, and there are good reasons to think about this rather than defaulting. Each director owes duties to that company. See a director's duties under the Companies Act.
5. Adopt the MOI. The parent controls the subsidiary, so a custom MOI is less about deadlock and more about reserving decisions to the parent.
6. File beneficial ownership. Not the parent — the natural persons behind the parent. Where a trust or another company sits above, you keep looking through. See beneficial ownership when your company is owned by a trust.
7. Set up the subsidiary as a separate business — its own bank account, its own records, its own tax registrations.
What a subsidiary actually is
Broadly, a company is a subsidiary where another company controls the majority of the voting rights, or can appoint or remove the majority of its directors.
A wholly owned subsidiary is one where the parent holds all the shares.
It is a separate legal person. Its debts are its own. Its contracts are its own. Its compliance obligations are its own. The parent is a shareholder, not a guarantor — unless the parent has signed a surety, which lenders often require and which quietly undoes much of the separation.
The two costs to price before you register
Small Business Corporation status
Gone, for the subsidiary, immediately. SBC status requires all shareholders to be natural persons. A company shareholder ends it.
And frequently gone for the parent too, because SBC status also requires that no shareholder holds shares in any other company — and the parent now does.
What that costs at 2026/27 rates:
| Taxable income | SBC tax | Standard 27% | Extra per year |
|---|---|---|---|
| R300,000 | R14,070 | R81,000 | R66,930 |
| R550,000 | R57,470 | R148,500 | R91,030 |
| R1,000,000 | R178,970 | R270,000 | R91,030 |
Two profitable companies both on 27% instead of SBC rates can cost R180,000 a year. That is the number to weigh the structure against. See what is a Small Business Corporation.
A second compliance calendar
Every year, for each company:
CIPC annual return and beneficial ownership, in its own anniversary month. The subsidiary registered in November has nothing in common with the parent registered in March. Two dates, and each company can be deregistered independently for missing its own. See what is your company's anniversary date
Annual financial statements
An income tax return and two provisional tax payments
Its own bank account, bookkeeping and records
And no group tax relief. South Africa does not allow one company's losses to be offset against another's profits. A loss-making subsidiary alongside a profitable parent means paying full tax on the profits while the losses sit unused — where in a single company they would have netted off.
Getting the intercompany relationship right
This is where subsidiary structures fail in practice.
Every transaction between the companies needs a written agreement at market-related terms. Management fees, rent, licence fees, loans, shared staff. "We just move money between them" is how the separation becomes a fiction, and a fiction is exactly what a court looks through.
Tax consequences follow each one. Management fees between VAT-registered companies attract VAT. Loans raise interest and deemed-interest questions. Anything crossing a border raises transfer pricing.
Keep the banking genuinely separate. Separate accounts, separate cards, no paying the subsidiary's suppliers from the parent's account because it was easier that day.
Directors must act for their own company. A director of the subsidiary who simply does what the parent wants, against the subsidiary's interests, is in breach of duty — a real issue where the subsidiary has minority shareholders or creditors.
When a subsidiary is the right answer
Ring-fencing genuine risk. A trading operation with real liability exposure, separated from the entity holding the valuable assets.
A distinct business with different customers, staff and risk profile.
Preparing to sell one part. Selling a subsidiary's shares is far cleaner than extracting assets from a single trading company.
An investor coming into one activity but not the whole business.
A specific licence or registration attaching to one activity.
When it is not
One business, split for the sake of it. You have bought compliance and lost SBC rates and solved nothing
To reduce tax. It generally increases it
Where you will not maintain the separation. A structure you do not respect gives no protection
Where a division would do. Separate reporting inside one company gives you the visibility without a second entity

Frequently asked questions
How do I register a subsidiary company in South Africa? Register it like any private company, with the parent company as subscriber and shareholder. The parent's board resolves to incorporate, you reserve the name, file the registration with the parent's documents, appoint directors, adopt the MOI, and file beneficial ownership looking through the parent to the natural persons.
Is there a special CIPC process for subsidiaries? No. A subsidiary is an ordinary private company. What makes it a subsidiary is that another company controls the majority of its voting rights or can appoint or remove the majority of its directors.
Does a subsidiary affect Small Business Corporation status? Yes, and often for both companies. The subsidiary loses SBC status because its shareholder is a company. The parent frequently loses it too, because SBC status requires that no shareholder holds shares in any other company.
Who is the beneficial owner of a subsidiary? The natural persons behind the parent, not the parent itself. Where a trust or a further company sits above the parent, you keep looking through until you reach people.
Can a subsidiary's losses reduce the parent's tax? No. South Africa does not allow group tax relief. Each company is taxed on its own result, so a loss-making subsidiary alongside a profitable parent means paying full tax on the profits while the losses sit unused.
Do the parent and subsidiary file annual returns at the same time? No. Each has its own anniversary date based on its own incorporation date, and each can be deregistered independently for missing its own filing.
Is the parent liable for the subsidiary's debts? Generally not — the subsidiary is a separate legal person and the parent is a shareholder. That changes where the parent has signed a surety, which lenders commonly require, or where the separation is not genuinely maintained.
Price the structure before you build it
A subsidiary costs a second compliance calendar and, usually, Small Business Corporation status for both companies. Where there is real risk to ring-fence or a business to sell separately, that is money well spent. Where there is not, it is just cost.
