VAT registration in South Africa, explained properly

When registration is compulsory

You must register as a VAT vendor when the value of your taxable supplies exceeds R2.3 million in any rolling 12-month period, or when you have a contractual commitment that will take you over R2.3 million in the coming 12 months. Before 1 April 2026 that threshold was R1 million, so a business that registered on the old number is not obliged to have done so today. Two things trip people up:

• It is rolling, not per financial year. Any consecutive 12 months count. A strong nine months can put you over before year-end does.
• The clock does not wait for you. Once you cross the threshold you must apply within 21 business days. Register late and SARS can hold you liable for VAT on sales made after you should have registered, VAT you never charged your customers and now pay out of your own margin.

Voluntary registration

A business with taxable supplies of at least R120 000 in the past 12 months may register voluntarily. Some categories can register below that where SARS is satisfied the business will reach it. Voluntary vendors take on exactly the same duties as compulsory ones, the choice is whether the benefits outweigh the admin, which we cover below.

What being a VAT vendor means practically

• You charge 15% on your sales. Every taxable sale carries output VAT at 15% (zero-rated and exempt supplies aside). That money is SARS's, not yours, treat it as collected on their behalf.
• You claim VAT back on purchases. Input VAT on business expenses from other vendors comes off what you owe, provided you hold valid tax invoices.
• Your invoices must comply. A valid tax invoice needs the words "tax invoice", your VAT number, the customer's VAT number on larger invoices, and the prescribed details. Sloppy invoices cost your customers their input claims, and sloppy supplier invoices cost you yours.
• You file VAT returns. Most vendors file a VAT201 every two months, with payment due with the return; some are put on monthly or other cycles depending on size and category. Nil returns are still returns.
• Your prices are VAT-inclusive to consumers. Advertised prices to the public must include VAT, so registering effectively raises your consumer prices or squeezes your margin by up to 15%.

Should you register voluntarily?

It tends to help when your customers are VAT-registered businesses (they claim your VAT back, so your price is not really higher to them), you buy significant VAT-bearing inputs (stock, equipment, fuel, rent from a vendor), or big clients and tenders treat a VAT number as a credibility filter.

It tends to hurt when you sell to the public, who cannot claim VAT back, registering makes you 15% more expensive or 15% less profitable overnight. It also adds real admin: return cycles, invoice discipline and record-keeping that SARS can audit. A service business with few inputs selling to consumers usually should not register before it must.

What SARS will ask you for

VAT registration is not a form you file and forget. SARS verifies most applications, and the ones that stall are the ones with gaps. Have all of this ready before you start.

• A registered representative already active on eFiling. Nothing happens until SARS recognises someone as authorised to act for the company. This is the single most common reason a registration goes nowhere.
• Proof you actually passed the threshold, or will. Invoices, signed contracts, bank statements or financial statements showing taxable supplies over R2.3 million in a rolling 12 months, or the written contract that commits you to it.
• For voluntary registration, proof of R120 000 in taxable supplies over the past 12 months. Without evidence, expect a refusal.
• A business bank account in the exact name of the registering entity. A personal account, or one in a trading name that does not match the registration, will fail verification.
• Proof of the business address, recent and in the entity’s name where possible.
• Identity documents for directors, members or the sole proprietor.
• A clear description of what you sell. SARS wants to understand the business, not a one-word answer.

Expect to be checked. SARS may request further documents or call the representative in for a validation appointment. Complete, consistent paperwork is the biggest factor in how fast this goes, and inconsistency between your bank account name, your CIPC name and your address is what triggers the delays.

How registration runs, step by step

1. Confirm you actually have to register. Watch the rolling 12 months, not your financial year.
2. Get the registered representative recognised on eFiling first, if that is not already done.
3. Assemble the supporting file: proof of turnover, bank account, address, identity documents.
4. Submit the VAT101 application through eFiling.
5. Respond to SARS verification promptly. Slow replies are what turn a two-week registration into a two-month one.
6. Once your VAT number is issued, start charging 15% and issuing proper tax invoices carrying that number, and diarise your filing cycle, usually every two months.

Registering late is expensive in a way people underestimate: you owe SARS the VAT on sales made from the date you should have registered, whether or not you charged it to your customers. That money comes out of your own pocket.

Common mistakes

• Watching the financial year instead of the rolling 12 months and registering months late, with historic VAT owed out of pocket.
• Charging VAT before the registration is approved. You may only charge VAT once you are registered; charging it without a VAT number is unlawful.
• Spending the VAT. The 15% collected is not revenue. Vendors who bank it as cash flow meet SARS debt, penalties and interest two months later.
• Claiming input VAT without valid tax invoices, or on items where claims are denied or limited, such as entertainment and most passenger vehicles.
• Missing return deadlines. Late VAT201s attract penalties and interest and turn your tax compliance status red, often discovered mid-tender.
