The fine print of buying a business: why VAT zero-rating is the quiet dealmaker in African M&A

For anyone who tracks the movement of capital across Africa, the most interesting moment in a deal is rarely the handshake. It is the hours spent arguing over what exactly is being sold — the company as a living organism, with all its scars and secrets, or just the parts that still work. In South Africa, that distinction carries a price tag that can shift the entire balance of a negotiation, and it is a lesson that resonates far beyond Johannesburg boardrooms.

The mechanics are straightforward on paper. When you buy shares, you inherit everything: the assets, the contracts, the debts, the lingering legal risks, the history you might rather not own. But when you buy the business itself, you get to pick. You can take the factory, the client list, the skilled staff, and leave behind the toxic lease or the lawsuit that has been festering for years. That cherry-picking power is why so many purchasers prefer an asset deal, especially in markets where due diligence can only reveal so much about what lurks in a company's past.

Yet the real sophistication in these transactions often lies in the tax treatment. Under South Africa's Value-Added Tax Act, a sale of a business as a going concern can qualify for VAT at the zero rate, rather than the standard rate. That is not a minor administrative detail. For a large acquisition, the difference can run into millions of rand, affecting how much cash the buyer needs upfront and how much the seller actually pockets after the state takes its share. Both sides know this, which is why the structure of the deal — and the wording of the contract — becomes a battlefield before the price is even finalised.

The conditions are strict and unforgiving. Both parties must be registered VAT vendors. The business must be capable of separate operation. The agreement must explicitly state, in writing and before or at the time of signing, that this is a going concern. The seller must hand over the assets necessary to run the enterprise, and nothing extraneous. And the parties must agree that the consideration includes VAT at the zero rate. Miss one step, and the South African Revenue Service can reclassify the entire sale as taxable at the standard rate, blowing up the financial model that made the deal viable in the first place.

A particularly thorny question arises when the business being sold has not yet crossed the compulsory VAT registration threshold of one million rand in taxable supplies over a year. Many small and medium enterprises in South Africa operate below that line, and a seller might assume the going-concern route is closed. But the law allows voluntary registration once taxable supplies exceed fifty thousand rand in the preceding twelve months — a threshold most operating businesses will meet. This opens the door for smaller transactions to enjoy the same zero-rating advantages, provided the paperwork is done in time and the parties are disciplined about the process.

For the international reader, this is a window into how wealth actually moves on the continent. Deals are not just about valuations and multiples; they are about legal architecture and tax strategy. The ability to structure an acquisition cleanly — to avoid a punitive VAT bill and to allocate risk intelligently — can determine whether a foreign investor sees South Africa as a viable entry point or a compliance minefield. It also shapes the behaviour of local buyers, who have learned that the difference between a good deal and a great one often lies in the clauses, not the headline number.

Looking ahead, as more African businesses mature and change hands — from family-owned firms to private equity portfolios — the sophistication of these structures will only grow. The going-concern provision is not just a technicality; it is a signal of how mature a market has become. Buyers who understand it can move faster and bid higher. Sellers who ignore it leave money on the table. In the end, the real price of a business is not what is announced in the press release, but what survives the taxman and the lawyers. That is the deal that actually matters.
