What is VAT?
Every time you buy something in South Africa, you pay VAT. It is right there on the receipt — 15% added to the price. But do you actually know what it is, where it goes, and why it matters? More importantly, if you run a business, do you understand that the VAT you collect from your customers is never really yours to begin with?
VAT is not your money
This is the most important thing I want you to take away from this article. VAT collected from your customers belongs to SARS. Full stop.
When a VAT-registered business adds 15% to an invoice, that 15% is collected on behalf of SARS. The business holds it temporarily, and then pays it over. Many business owners have landed themselves in serious trouble by treating that money as part of their cash flow. It is not. Spending VAT collected before paying it over to SARS is one of the fastest ways to find yourself facing penalties, interest, and a very uncomfortable conversation with the taxman.
So what exactly is VAT?
VAT stands for Value-Added Tax. It is an indirect tax on the consumption of goods and services in South Africa, governed by the Value-Added Tax Act 89 of 1991 and administered by SARS.
The way it works is straightforward in principle. VAT is charged at each stage of the production and distribution chain, but the final burden always falls on the end consumer. Businesses act as the collection agents in between. In terms of section 7 of the VAT Act, VAT is levied at the standard rate of 15% on the supply of goods or services by a registered vendor.
Think of it this way. The corner café, the wholesaler who supplied them, and the manufacturer who supplied the wholesaler – each one charges VAT and each one claims back the VAT they paid to their own suppliers. By the time the product reaches you, SARS has collected its share at every step along the way. You, as the final consumer, bear the full cost.
Output tax and input tax – the two sides of VAT
If you run a business and you are registered for VAT, you deal with two things every tax period.
Output tax is the VAT you charge your customers on sales. Input tax is the VAT you pay your suppliers on purchases. The difference between the two is what you pay over to SARS — or in some cases, what SARS refunds to you.
A simple example. Say your business invoices R100,000 in a month. You add 15% VAT, so you collect R15,000 in output tax. During that same month, you bought supplies and paid R6,000 in VAT to your suppliers. That R6,000 is your input tax. At the end of the period, you pay SARS the difference – R9,000. The VAT system ensures that tax is only paid on the value added at each stage, not on the full amount every time goods change hands.
Do you need to register for VAT?
Not every business needs to register. In terms of section 23 of the VAT Act, registration becomes compulsory once your taxable supplies exceed R3.2 million in any consecutive 12-month period. That threshold is based on turnover, not profit.
If your turnover is below R3.2 million, you can still register voluntarily – provided your taxable supplies have exceeded R50,000 in the past 12 months. There are good reasons to consider voluntary registration, which we cover in a separate article.
It is also worth noting that you must apply for registration within 21 business days of becoming liable. Missing that deadline opens the door to back-dated VAT liability, penalties, and interest. It is not something to leave until later.
What happens if you get it wrong?
VAT is unforgiving when mismanaged. I have seen it happen. A business invoices clients, collects VAT, and then uses that money to cover operating costs. When the VAT return comes due, the funds are gone. SARS does not accept cash flow problems as a reason for non-payment. Penalties and interest are applied automatically, and SARS has extensive powers under the Tax Administration Act to recover what is owed.
Getting VAT wrong is one of the fastest ways to get into trouble with SARS. And it is almost always avoidable with the right systems in place.
The bottom line
VAT is not complicated once you understand its basic logic. It is a consumption tax collected by businesses on behalf of SARS, with the final burden falling on the consumer. If you are in business, understanding your VAT obligations is not optional. It is a legal requirement from the moment you cross the registration threshold.
