How SARS VAT Invoicing Works

A practical guide to VAT invoicing in South Africa. Understand the SARS requirements, avoid common mistakes, and stay compliant.

What Is VAT?

Value Added Tax (VAT) is a consumption tax charged on most goods and services in South Africa at 15%. As a VAT vendor, you collect VAT from customers and pay it to SARS, minus the VAT you've paid on business purchases.

Understanding how SARS VAT invoicing works is essential for any South African business. Get it right, and VAT is straightforward. Get it wrong, and you face penalties, audits, and unhappy customers who can't claim their input VAT.

The VAT Process

1

VAT Registration

Register with SARS when turnover exceeds R1 million (mandatory) or R50,000 (voluntary). You'll receive a VAT registration number.

2

Charge VAT on Sales

Add 15% VAT to your taxable supplies. This is 'output VAT' that you collect on behalf of SARS.

3

Issue Tax Invoices

Provide SARS-compliant tax invoices to customers. These allow them to claim input VAT.

4

Claim Input VAT

Deduct VAT paid on business purchases from VAT collected. Keep tax invoices as proof.

5

Submit VAT Returns

File VAT201 returns (usually bi-monthly) via eFiling. Pay the difference between output and input VAT.

Tax Invoice Requirements

SARS requires specific information on tax invoices. Missing any of these can invalidate the invoice for VAT purposes:
