Can I issue a tax invoice if I am not VAT registered?

No. Only VAT-registered vendors may issue a document called a 'tax invoice' or charge VAT. If you are not registered, call it an 'invoice', show no VAT line, and do not add 15% to your prices.

When do I need a full tax invoice instead of an abridged one?

When the total including VAT is more than R5,000, a full tax invoice is required, including the buyer's name and address (and VAT number if they are registered). At R5,000 or under, an abridged tax invoice without buyer details is acceptable. Under R50, no tax invoice is required at all — a till slip is enough.

Do invoices in South Africa need an invoice number?

Yes — every tax invoice needs an individual serialised number. Sequential numbering (INV-0001, INV-0002…) is the accepted standard and makes reconciliation and SARS queries much easier.

Invoice requirements in South Africa: what SARS actually wants

Updated 22 July 2026 · 6 min read · General information, not tax advice

If you invoice customers in South Africa, there are really only two questions that matter: are you VAT registered, and is the invoice over R5,000? Those two answers decide everything about what must appear on the document. Here is the whole picture, in plain English.

First: are you a VAT vendor or not?

This is where most small businesses get it wrong, in both directions.

Not VAT registered? You issue a plain invoice. You may not call it a "tax invoice", you may not show a VAT number you don't have, and you may not add 15% VAT to your prices. Charging VAT without being registered is an offence — and it also makes you 15% more expensive for no reason.
VAT registered? You must issue a proper tax invoice for standard-rated supplies, and your customers need it to claim their input VAT. A non-compliant invoice can cost your customer their VAT claim — which is a fast way to lose a business client.

Registration becomes compulsory once your taxable turnover passes R1 million in any 12-month period. You can register voluntarily from R50,000. Under that, stay a plain invoicer — it's simpler.

The R5,000 rule: full vs abridged tax invoices

For VAT vendors, SARS accepts two levels of tax invoice depending on the total (including VAT):

Invoice total (incl. VAT)	What's required
Under R50	No tax invoice needed — keep the till slip or receipt as proof.
R50 – R5,000	Abridged tax invoice — your details, not the buyer's.
Over R5,000	Full tax invoice — including the buyer's name, address and VAT number (if registered).

What a full tax invoice must contain

The words "Tax Invoice", "VAT Invoice" or "Invoice" displayed clearly
Your (the seller's) name, address and VAT registration number
The buyer's name, address and VAT number if they're registered (required over R5,000)
An individual serialised invoice number and the date of issue
A description of the goods or services
The quantity or volume supplied
The value and the VAT — either the VAT amount shown separately, or a statement that VAT at 15% is included in the price

An abridged tax invoice (R5,000 and under) drops the buyer's details and the quantity — but still needs the words "Tax Invoice", your details and VAT number, a serial number, date, description, and the consideration with VAT.

What it looks like in practice

TAX INVOICE — INV-0043 Naledi Plumbing CC · 12 Main Rd, Salt River, Cape Town VAT No: 4123456789 · 22 July 2026 To: Bright Traders (Pty) Ltd, 4 Long St, CT · VAT 4987654321 Geyser replacement (labour) 1 R2,800.00 Kwikot 150L geyser 1 R4,650.00 Subtotal R7,450.00 VAT @ 15% R1,117.50 TOTAL R8,567.50

Total is over R5,000, so the buyer's details are on it. If this plumber weren't VAT registered, the same invoice would say just "INVOICE", show no VAT number and no VAT line, and the total would simply be the price.

Non-VAT invoice checklist (most small businesses)

The word "Invoice" (not "Tax Invoice")
Your business or trading name and contact details
Invoice number and date
Customer name
Description, quantity and price per line
Total — no VAT line
Your banking details and payment terms (e.g. "Payable within 7 days")

Banking details and payment terms aren't SARS requirements — they're getting-paid requirements. An invoice without banking details is a donation request.

Common questions

Can I issue a tax invoice if I'm not VAT registered?

No. Only VAT vendors may issue "tax invoices" or charge VAT. Use a plain invoice with no VAT line.

Do quotes need to meet these requirements?

No — a quote is an offer, not a tax document. But converting an accepted quote into a compliant invoice is where mistakes creep in. See quote vs invoice.

Must invoices be sequentially numbered?

Each tax invoice needs its own serialised number. Sequential (INV-0001, 0002…) is the standard and makes SARS queries painless.

How long must I keep invoices?

Five years, for SARS. Digital copies are fine — a PDF emailed to yourself and your customer covers it.
