VAT Invoice Requirements in South Africa: Full and Abridged

A VAT vendor can only claim input VAT on an expense if the supporting document is a valid tax invoice under section 20 of the VAT Act 89 of 1991. If the invoice is missing a required field, SARS can disallow the input VAT claim during an audit or verification - regardless of whether the purchase was genuinely for business purposes (SARS: VAT Invoice Requirements, 2024).

Key Takeaways

Full tax invoice required for transactions above R5,000 (including VAT) - must include both supplier and recipient VAT numbers.

Abridged tax invoice used for R5,000 and below - recipient VAT number not required.

The document must say “Tax Invoice” - not just “Invoice” - to be valid for input VAT purposes.

Only invoices from registered VAT vendors generate a valid input VAT claim.

Two types of VAT invoice

Section 20 of the VAT Act 89 of 1991 distinguishes between full and abridged tax invoices based on the transaction value (legislation.gov.za).

Full tax invoice (transactions above R5,000 including VAT)

Required when the consideration for the supply (including VAT) exceeds R5,000. Must contain all of the following:

The words “Tax Invoice” prominently on the document.
Name, address, and VAT registration number of the supplier.
Name, address, and VAT registration number of the recipient (where the recipient is a VAT vendor).
A unique sequential invoice number.
The date of issue.
A description of the goods or services supplied.
The quantity or volume of goods or services.
The consideration (total amount charged) in rand.
The VAT amount charged, stated separately from the price.
The tax-inclusive price (or the tax-exclusive price and tax separately itemised).

Abridged tax invoice (transactions R5,000 or below including VAT)

May be used for smaller transactions. Required fields:

The words “Tax Invoice” on the document.
Name, address, and VAT registration number of the supplier.
A serial number and date of issue.
A description of the goods or services supplied.
The consideration including VAT.
Either the VAT amount or a statement that the consideration includes VAT at 15%.

The recipient’s VAT number is not required on an abridged invoice.

What is NOT a valid tax invoice

The following documents do not qualify as tax invoices for input VAT purposes (SARS: VAT):

A quote or pro forma invoice - these pre-date the supply and don’t record an actual transaction.
A statement - a summary of outstanding balances is not an invoice for an individual supply.
A document headed “Invoice” without the word “Tax” - technically non-compliant; SARS uses this as grounds to challenge a claim.
An invoice from a non-VAT vendor - they cannot charge VAT; there is no input VAT to claim.
An invoice for a zero-rated or exempt supply - no VAT was charged, so no input VAT arises.

Your VAT number on supplier invoices

For invoices above R5,000, your VAT registration number must appear on the invoice to support a valid input VAT claim. Ensure your suppliers have your VAT number and include it on high-value invoices. For invoices of R5,000 and below, your number is not required.

Electronic tax invoices

Electronic invoices - typically PDF files delivered by email - are acceptable provided they contain all required fields and can be retrieved and printed on request during a SARS audit (SARS: Record-keeping). Store all electronic invoices securely with backups. The five-year retention rule applies.

Credit notes and debit notes

When a supply is cancelled, reduced, or incorrectly invoiced, the VAT vendor must issue a credit note (to reduce an invoice) or debit note (to increase it). These documents must contain similar fields to a tax invoice and must be linked to the original invoice in your VAT records.

A worked example: why a claim gets disallowed

A consulting firm pays R11 500 (including VAT) for office furniture and claims the input VAT. On audit, SARS disallows it. Why? The supplier’s document was headed “Invoice”, not “Tax Invoice”, and - because the amount was over R5 000 - it left off the firm’s own VAT number. Both are mandatory fields for a full tax invoice.

The purchase was genuine and clearly for business use, but the document did not meet section 20, so the R1 500 of input VAT was lost until a corrected tax invoice was obtained from the supplier. The lesson: check high-value invoices the day they arrive, not when SARS asks for them.

Consequences of non-compliant invoices

Your input VAT claim may be disallowed during a SARS audit or VAT verification - even if the expense was a genuine business cost.
Clients receiving your non-compliant invoices may refuse to pay until a corrected invoice is issued.
Repeated non-compliance can attract SARS penalties under the Tax Administration Act.

Frequently Asked Questions

What is the difference between a full tax invoice and an abridged tax invoice?

A full invoice is required for transactions above R5,000 (including VAT) and must include both the supplier’s and recipient’s VAT registration numbers, a sequential number, date, description, quantity, amount, and VAT stated separately. An abridged invoice is used for R5,000 and below - it requires supplier details, description, amount, and a statement that VAT is included, but not the recipient’s VAT number.

Can I claim input VAT from a supplier who is not registered for VAT?

No. Input VAT can only be claimed on a valid tax invoice from a registered VAT vendor. If your supplier is not VAT-registered, no VAT has been charged and there is no input VAT to claim. Claiming input VAT on an unregistered supplier’s invoice is a misstatement that SARS will disallow.

Is a statement or quote a valid tax invoice for input VAT?

No. Statements summarise outstanding amounts across multiple transactions and do not qualify as tax invoices for individual supplies. Quotes are pre-sale and don’t record a completed supply. SARS requires a tax invoice for each supply - a specific document containing all required fields and the words “Tax Invoice.”

What should I do if a supplier sends me a non-compliant invoice?

Do not claim the input VAT on a defective document. Ask the supplier to reissue a corrected tax invoice with the missing fields - the correct heading, both VAT numbers (for amounts above R5,000), a serial number, and VAT shown properly. Only claim once you hold a compliant invoice. Claiming first and hoping to fix it later is exactly what SARS reverses on verification.

How long must I keep tax invoices?

Tax invoices must be kept for at least five years from the date you file the VAT return in which you claimed the input VAT. Electronic storage is acceptable, but ensure files are backed up and can be retrieved and printed on request during a SARS audit.
