What is VAT and Why Does It Matter?
Value Added Tax (VAT) is an indirect tax collected by businesses on behalf of SARS (South African Revenue Service). As a business, you collect VAT from your customers on your sales, pay VAT on your purchases, and remit the difference to SARS. Simple in principle — but the details matter enormously.
The current VAT rate in South Africa is 15%, unchanged since April 2018. This applies to most goods and services. Some items are zero-rated (like basic foodstuffs) and some are exempt — understanding the difference is critical to avoiding costly errors.
When Must You Register for VAT?
VAT registration is compulsory when your taxable turnover exceeds — or is likely to exceed — R1 million in any consecutive 12-month period. This is called the compulsory registration threshold.
You must apply to SARS for VAT registration within 21 days of reaching this threshold. Failing to register on time results in penalties and interest on the VAT you should have collected.
📌 Voluntary VAT Registration
You can voluntarily register for VAT if your turnover exceeds R50,000 in a 12-month period. Many small businesses benefit from this because it allows them to claim back VAT on their business purchases — turning VAT from a cost into a cash flow advantage.
How to Calculate VAT Correctly
There are two calculations you'll do constantly as a VAT vendor:
Adding VAT to a price (charging your customers)
VAT Amount = Price (excl. VAT) × 15%
Example: R1,000 (excl.) → VAT = R150 → Total = R1,150
Extracting VAT from a VAT-inclusive price
When a price already includes VAT and you need to find the VAT portion:
VAT Portion = Price (incl. VAT) × 15/115
Example: R1,150 (incl.) → VAT = R1,150 × (15/115) = R150
Your VAT Return (Output Tax vs Input Tax)
Every VAT period, you calculate:
- Output tax — VAT collected on your sales
- Input tax — VAT you paid on business purchases
- If output > input: you pay SARS the difference
- If input > output: SARS owes you a refund
VAT Filing Periods and Deadlines
Most small businesses file VAT returns every two months (bi-monthly). SARS assigns your tax period based on when you registered. Larger businesses may file monthly.
The deadline is the 25th of the month following your tax period end (or the last business day before if the 25th falls on a weekend or public holiday). For eFiling submissions with electronic payment, SARS sometimes extends this slightly.
⚠️ Late Submission Penalties
Missing a VAT deadline results in a 10% penalty on the outstanding amount, plus interest at the prescribed rate. If you can't pay on time, still submit on time — the late submission penalty is separate and additional to the late payment interest.
5 Common VAT Mistakes South African Small Businesses Make
Not keeping valid tax invoices
To claim input tax, you need a valid tax invoice from the supplier — one that includes their VAT number, your details, description of goods/services, VAT amount, and total. Receipts without all these details may not qualify. SARS can disallow your input tax claim without proper documentation.
Claiming VAT on exempt purchases
Some purchases — like insurance, residential rent, and certain financial services — are VAT-exempt. You cannot claim input tax on these, even if you're a registered VAT vendor. Many business owners accidentally try to claim these back.
Mixing personal and business expenses
Personal expenses have no place in your VAT return. Claiming input tax on groceries, personal travel, or personal subscriptions is a red flag for SARS audits — and a disqualifiable expense.
Using cash basis when you should use invoice basis
SARS defaults most vendors to the invoice basis — VAT is accounted for when an invoice is issued, not when payment is received. This catches many businesses off guard when a client delays payment but the VAT is already due.
Poor record-keeping
SARS requires you to keep all VAT records for a minimum of 5 years. Paper receipts fade, get lost, and pile up. A SARS audit without supporting documents means disallowed input tax claims and potential penalties.
How the Right Software Makes VAT Compliance Simpler
Managing VAT manually — tracking invoices in spreadsheets, calculating output vs input tax by hand, hunting for paper receipts at month-end — is both time-consuming and error-prone.
Business management software purpose-built for South Africa handles much of this automatically. A good platform should:
- Calculate and apply 15% VAT on invoices automatically
- Track input tax on purchases separately
- Generate a VAT summary report at the end of each filing period
- Store digital copies of tax invoices with all required fields
- Send reminders before VAT deadlines
Task4U's SA Tax Module is built specifically for this. It handles VAT, PAYE, UIF and SDL calculations natively and generates SARS-ready reports — so at the end of each period, your VAT return takes minutes rather than days. The photo reconciliation feature lets your team snap receipts in the field, automatically extracting and categorising the VAT component, which keeps your input tax records accurate without manual data entry.
Key Takeaways
- Register for VAT once your turnover hits R1 million — and consider voluntary registration at R50,000
- The VAT rate is 15% — apply it consistently and extract it correctly
- Always keep valid tax invoices to support input tax claims
- Submit your VAT return by the 25th of the month following your tax period — even if you can't pay yet

- Use software that automates VAT calculations and stores your records digitally
