What Is a Tax Invoice in South Africa?
A tax invoice is a document issued by a VAT-registered business (vendor) in South Africa when they make a taxable supply of goods or services. It is governed by the Value-Added Tax Act, No. 89 of 1991 and regulated by the South African Revenue Service (SARS).
The key purpose of a tax invoice is to allow the recipient (buyer) to claim back input VAT from SARS. Without a valid tax invoice, no input VAT deduction can be claimed.
Only VAT-registered vendors may issue tax invoices. If your annual taxable turnover is below R1 million, you are not required to register for VAT. Businesses that are not VAT-registered must never head their documents "Tax Invoice" — use "Invoice" instead.
What Must a Tax Invoice Include? (Full Tax Invoice)
A full tax invoice is required when the supply exceeds R5,000 (inclusive of VAT). It must contain all of the following:
- ✓ The words "Tax Invoice" displayed prominently
- ✓ Supplier's name and address
- ✓ Supplier's VAT registration number
- ✓ Invoice date (date of supply)
- ✓ Unique, sequential invoice number
- ✓ Recipient's name and address
- ✓ Description of the goods or services supplied
- ✓ Quantity and unit price of goods or services
- ✓ Subtotal excluding VAT
- ✓ VAT amount charged (15%)
- ✓ Total amount including VAT
Abridged Tax Invoice (Supplies Under R5,000)
For supplies of R50 to R5,000 inclusive of VAT, a simplified abridged tax invoice is permitted. It requires fewer fields:
- The words "Tax Invoice"
- Supplier's name, address, and VAT registration number
- Invoice date and number
- Description of the supply
- VAT amount OR a statement that the price includes VAT at 15%
- Total amount (VAT inclusive)
Note: The recipient's name and address are not required on an abridged tax invoice.
No tax invoice is required for supplies under R50 (inclusive of VAT), though you may still choose to issue one.
Tax Invoice vs Regular Invoice — What's the Difference?
| Feature | Tax Invoice | Regular Invoice |
|---|---|---|
| Who can issue it | VAT-registered vendors only | Any business |
| Heading | Must say "Tax Invoice" | "Invoice" or similar |
| VAT number required | Yes | No |
| VAT amount shown separately | Yes (for full tax invoice) | No requirement |
| Allows input VAT claim | Yes — buyer can claim back VAT | No |
| SARS audit trail | Required for VAT returns | Not directly used for VAT |
How to Create a SARS-Compliant Tax Invoice
Head it "Tax Invoice"
The words must appear prominently. "Invoice" alone is not sufficient — SARS can disallow input VAT claims if the document is not correctly headed.
Include your VAT registration number
Your VAT number issued by SARS must appear on every tax invoice. Format: VAT Reg No. 4XXXXXXXXX. Without this, the invoice is not a valid tax invoice.
Number invoices sequentially
Each invoice needs a unique, consecutive number (e.g. INV-001, INV-002). Gaps or duplicates in your invoice sequence can trigger SARS audit queries.
Add the recipient's details (full invoices)
For supplies over R5,000, include the buyer's name and address. This is mandatory — not optional — for a full tax invoice.
Describe the supply clearly
Be specific. "Labour" is less useful than "Waterproofing — 60m² flat roof, Lanxess membrane applied." Vague descriptions increase audit risk.
Show VAT separately
Display: Subtotal (excl. VAT) / VAT at 15% / Total (incl. VAT) as three separate lines. All three are required on a full tax invoice.
VAT on Invoices — Quick Rules for SA Tradespeople
- Standard rate: 15% on most goods and services (including labour)
- VAT threshold: You must register for VAT once taxable turnover exceeds R1 million/year. Voluntary registration is allowed from R50,000/year.
- Calculation: To add VAT: multiply by 1.15. To extract VAT from a VAT-inclusive price: multiply by 15/115 (= 0.130435).
- Zero-rated: Some supplies attract 0% VAT (certain food, exports). Tradespeople are almost always on standard 15%.
- Non-VAT registered: Do not charge VAT. Do not show VAT on your invoice. Do not head your invoice "Tax Invoice".
If you're not registered for VAT, simply issue a regular invoice showing your total price. Do not mention VAT, do not include a VAT line, and do not use the words "Tax Invoice". You can still use a professional invoice template — just head it "Invoice" and omit the VAT section entirely.
Common Tax Invoice Mistakes SA Tradies Make
- Calling it a "Tax Invoice" without a VAT number — invalid. SARS can penalise the issuer and disallow the buyer's input VAT claim.
- No sequential invoice number — every invoice must be numbered. Unnumbered invoices are a red flag in SARS audits.
- Missing recipient details on invoices over R5,000 — the buyer's name and address are mandatory on full tax invoices.
- VAT not shown separately — a line showing only the total is not compliant. Subtotal, VAT, and total must appear as separate lines.
- Using the wrong date — the date on the invoice must be the date of supply (when the service was rendered), not the date you got around to sending the invoice.
