VAT invoice requirements for South African small businesses

What SARS actually requires on an invoice, by transaction size — and what happens if a required field is missing.

This page is general information for South African VAT vendors, not tax advice. Requirements can change, and your specific situation may differ — confirm with SARS or a registered tax practitioner before relying on this for a compliance decision.

South Africa's three-tier invoice system

The VAT Act sets different documentation requirements depending on the VAT-inclusive value of a supply:

Above R5,000 — a full tax invoice is required, with every prescribed field present.
R50 to R5,000 — an abridged tax invoice is permitted, which may leave out some recipient details.
R50 or less — no formal tax invoice is required; a till slip or sales docket showing VAT is generally enough.

Full tax invoice: what must be included (supplies above R5,000)

For a supply over R5,000, a valid full tax invoice must generally include:

The words “Tax Invoice”, “VAT Invoice”, or “Invoice”
The supplier's name, address, and VAT registration number
The recipient's name, address, and VAT registration number
A serial number and the date of issue
An accurate description of the goods or services supplied
The quantity or volume of goods/services
The value of the supply, the VAT amount charged, and the VAT-inclusive total (shown either separately, or as a VAT-inclusive price with a statement that VAT is included and the rate charged)

Missing even one required field can invalidate the document for the recipient's input VAT deduction purposes — which is a common reason a customer's bookkeeper sends an invoice back for correction.

Abridged tax invoice: what can be left out (R50–R5,000)

For supplies between R50 and R5,000, an abridged tax invoice is permitted and may omit the recipient's name, address, and VAT registration number. It must still include:

The words “Tax Invoice”, “VAT Invoice”, or “Invoice”
The supplier's name, physical address, and VAT registration number
A serial number and date of issue
An accurate description of goods or services
The value of the supply and the amount of VAT charged (or a VAT-inclusive price with the rate stated)

The 21-day rule

A valid tax invoice must be issued within 21 days of the supply being made — in field service terms, generally 21 days from when the job was completed, not from when a quote was accepted. Generating the invoice directly from a completed work card or accepted quote, rather than reconstructing it later from memory, is the most reliable way to stay inside that window.

Where this fits in the job cycle

None of this changes how you quote or complete a job on-site — a work card capturing the scope, materials, and client sign-off remains a record of what was done, separate from the invoice itself. See our quote-to-invoice guide for how the full cycle fits together.

Frequently asked questions

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

A full tax invoice is required when the VAT-inclusive value of a supply exceeds R5,000, and it must include both the supplier’s and recipient’s full names, addresses, and VAT registration numbers. An abridged tax invoice can be used for supplies between R50 and R5,000, and may leave out the recipient’s name, address, and VAT number.

Do I need any invoice at all for a very small sale?

For supplies of R50 or less, SARS does not require a formal tax invoice — a till slip or sales docket showing the VAT charged is generally sufficient.

How long do I have to issue a tax invoice after doing the work?

The VAT Act requires a valid tax invoice to be issued within 21 days of the supply being made.

Does a job card or work card count as a tax invoice?

No. A work card or job card is a record of the work performed and signed off by the customer — it supports the invoice but doesn’t replace it. The tax invoice is a separate document that must independently meet SARS’s formatting requirements.
