A South African tax invoice must contain 15 specific fields as required by the South African Revenue Service (SARS). The exact requirements depend on the transaction value: invoices above R5,000 require all 15 fields (a “full tax invoice”), while invoices between R50 and R5,000 only need 8 fields (an “abridged tax invoice”).
Getting this right matters. SARS can disallow a VAT vendor’s input tax claim if the supporting invoice does not meet the requirements, which means your client could lose the right to claim back the VAT they paid you.
What is the difference between a full and abridged tax invoice?
SARS distinguishes between two types of VAT invoices based on transaction value:
| Invoice type | Applies when | Fields required |
|---|---|---|
| Full tax invoice | Transaction is R5,000 or more (incl. VAT) | 15 mandatory fields |
| Abridged tax invoice | Transaction is R50 to R4,999.99 (incl. VAT) | 8 mandatory fields |
| No tax invoice required | Transaction is under R50 | Receipt is sufficient |
What fields are required on a full tax invoice?
A full tax invoice (for transactions of R5,000 and above) must include all of the following:
- The words “Tax Invoice” prominently displayed on the document
- The supplier’s name (your registered business name)
- The supplier’s address (physical address)
- The supplier’s VAT registration number
- A unique, sequential invoice number (e.g. INV-2026-001)
- The date the invoice is issued
- The recipient’s name (your client’s registered business name)
- The recipient’s address
- The recipient’s VAT registration number (if they are a VAT vendor)
- A description of the goods or services supplied
- The quantity or volume of goods or services
- The value of the supply, excluding VAT (the subtotal before VAT)
- The rate of VAT charged (currently 15%)
- The VAT amount (shown separately in rands)
- The total amount, including VAT (the final payable amount)
What fields are required on an abridged tax invoice?
For transactions between R50 and R4,999.99, the abridged tax invoice only requires:
- The words “Tax Invoice” on the document
- Your name (or trading name) and VAT registration number
- A unique, sequential invoice number
- The date the invoice is issued
- A description of the goods or services
- The total amount, including VAT
- Either: the VAT amount separately, or a statement that the total includes VAT at 15%
Note: abridged tax invoices do not need to include the recipient’s details.
What if my business is not VAT registered?
If your business is not registered for VAT, you cannot charge VAT and must not issue a “tax invoice.” You issue a standard invoice instead. Standard invoices have no SARS-mandated format, but should still include your business details, the client’s details, a unique invoice number, a description of services, and the amount payable.
VAT registration becomes mandatory once your taxable turnover exceeds R1 million in a 12-month period. See our guide on whether to register for VAT in South Africa for more detail.
What happens if an invoice is non-compliant?
If a tax invoice does not contain all the required fields, SARS can:
- Disallow your client’s input tax claim, meaning they cannot reclaim the VAT they paid you. This damages your client relationship.
- Raise an assessment against you if your own output VAT returns are found to rely on non-compliant invoices.
- Apply penalties and interest in cases of repeated or deliberate non-compliance.
In practice, SARS rarely penalises isolated errors on otherwise compliant invoices, but the risk is real and easily avoided by using invoicing software that generates compliant invoices automatically.
Quick answer
What must appear on a South African tax invoice?
A full South African tax invoice (for transactions of R5,000 or more) must include 15 mandatory fields as required by SARS: the words “Tax Invoice,” the supplier’s name, address, and VAT registration number, a unique sequential invoice number, the invoice date, the recipient’s name and address, the recipient’s VAT number if applicable, a description of goods or services, the quantity, the value excluding VAT, the VAT rate (currently 15%), the VAT amount in rands, and the total amount including VAT. For transactions between R50 and R4,999.99, an abridged tax invoice with only 8 fields is acceptable, and you do not need to include the client’s details. Invoices under R50 only require a receipt. Non-compliant invoices can result in SARS disallowing your client’s input VAT claim.

Frequently asked questions
Does SARS require a specific invoice format or template?
SARS does not prescribe a specific format or template. What matters is that all required fields are present. You can use any invoicing software, Word template, or accounting system as long as the invoice contains the 15 mandatory fields for full tax invoices or 8 fields for abridged tax invoices.
Can I issue a tax invoice in a foreign currency?
Yes, but the VAT amount must be converted to South African rands at the exchange rate on the date of supply. SARS requires the rand equivalent to be shown on the invoice if you invoice in a foreign currency. You should specify both the foreign currency amount and the ZAR equivalent.
What is the difference between a tax invoice and a proforma invoice?
A tax invoice is a legal document that records a completed sale and creates an obligation to pay. A proforma invoice is an estimate or quote sent before the work is done. Proforma invoices are not official tax invoices and cannot be used by the recipient to claim input VAT. Always send a proper tax invoice once the work is complete.
Must a tax invoice be in English?
SARS does not specifically require invoices to be in English. However, all information must be legible and accurate. In practice, most South African businesses issue invoices in English, and this is the safest approach for cross-border transactions and audits.
