How to create a VAT-compliant tax invoice in South Africa

A practical guide to SARS VAT 404 requirements, written for sole traders and small business owners, not accountants.

TAX INVOICE vs INVOICE: what's the difference?

In South Africa, the document title on your invoice is not cosmetic. It has a legal meaning under the Value-Added Tax Act, 1991.

TAX INVOICEThe correct title if you (the seller) are registered for VAT with SARS. This document allows your VAT-registered clients to claim back the VAT as an input tax credit.
INVOICEThe correct title if you are not VAT-registered. You are not charging VAT, and calling it a "Tax Invoice" would be incorrect and potentially fraudulent.

The rule is simple: if you have a VAT registration number from SARS, your document must say "TAX INVOICE". If you don't, it must say "INVOICE".

SARS requirements for a valid tax invoice

SARS publishes its VAT requirements in the VAT 404 guide (available on sars.gov.za). For a tax invoice to be valid and allow your client to claim input VAT, it must include:

✓

The words "TAX INVOICE": Must appear clearly on the document.

✓

Your VAT registration number: Your 10-digit SARS VAT number (e.g. 4123456789).

✓

The date of issue: When the invoice was created.

✓

An invoice number: A unique, sequential number to identify the document.

✓

Your business name and address: The seller's full details.

✓

The buyer's name and address: Required for invoices above R5 000 (see below).

✓

Description of goods or services: Clear enough for the buyer to identify what they're paying for.

✓

Quantity and price per unit: Both the unit price and total for each line item.

✓

The VAT amount: Must be shown separately, not included in the total without disclosure.

✓

The total amount: The full amount payable, including VAT.

Simplified vs full tax invoices:SARS allows a "simplified" tax invoice for supplies of R5 000 or less; you don't need the buyer's name and address. For any invoice above R5 000, a full tax invoice with buyer details is required for the buyer to claim input VAT.

When do you need a VAT number?

You are required to register for VAT if your taxable supplies exceed R1 million in any 12-month period. Below that threshold, VAT registration is voluntary, but some businesses choose to register earlier to be able to reclaim VAT paid on business expenses.

If you are not VAT-registered, you simply charge your price without adding VAT. Your invoice is titled "INVOICE", not "TAX INVOICE", and you do not include a VAT line. There is nothing wrong with this: most small SA businesses are not VAT-registered.

See our guide on when and how to register for VAT in South Africa if you're approaching the threshold or considering voluntary registration.

Handling a VAT-registered client

If your client is also VAT-registered, they will need your tax invoice to claim back the VAT they paid you as an input tax credit. For invoices above R5 000, your invoice should also include the client's VAT registration number. This isn't always required by SARS (it's required for the client's claim, not your obligation to file), but including it avoids disputes with the client's accountant.

VAT on individual line items

Not all goods and services are subject to VAT at 15%. South Africa has three VAT categories:

Standard rated (15%): most goods and services.
Zero-rated (0%): certain food items (basic foodstuffs like bread, maize, cooking oil), exported goods, and some financial services.
Exempt: residential rental, certain educational services, and public transport.

For most sole traders selling services, all your items will be standard-rated at 15%. If you sell a mix, mark each line item appropriately. Some invoicing tools (including SortedNexus) let you toggle VAT on or off per line item.
