If you're running a small business in South Africa, VAT is one of those things that sounds more complicated than it actually is, right up until you get it wrong. Here's the version without the jargon.
What VAT actually is
Value-Added Tax is a tax on the sale of most goods and services, currently charged at a standard rate of 15%. As a VAT-registered business, you charge VAT on what you sell (output VAT) and you can claim back the VAT you paid on business expenses and purchases (input VAT). What you owe SARS each period is simply the difference: output VAT collected, minus input VAT you're entitled to claim back.
Who has to register
Registration isn't optional once you cross a certain size.
- Compulsory registration once your taxable turnover exceeds R2.3 million in any rolling 12-month period (raised from R1 million, effective 1 April 2026, the first increase since 2009).
- Voluntary registration is available once your turnover passes R120,000 (raised from R50,000) even if you're well under the compulsory threshold, some businesses register early so they can claim input VAT on setup costs.
Below the voluntary threshold, you generally can't register at all, VAT simply doesn't apply to your invoices yet.
Charging VAT correctly
Once registered, every taxable invoice you issue needs to show VAT clearly, usually as a separate line showing the VAT amount and your VAT registration number. Get this wrong (charging VAT before you're registered, or forgetting to charge it once you are) and it becomes your problem to fix retroactively, not your customer's.
The VAT201 return
The VAT201 is the return you submit to SARS, usually monthly or every two months depending on your category, declaring your output VAT, your input VAT, and the net amount due (or the refund owed to you, if input exceeded output that period). It's filed online through SARS, and it needs to reconcile against your actual books, not an estimate.
Where small businesses usually go wrong
- Claiming input VAT without a valid tax invoice. SARS wants the actual document, not just a bank statement showing you paid for something.
- Mixing VAT-inclusive and VAT-exclusive pricing across quotes, invoices and reports, which throws every downstream total off.
- Manually recalculating VAT in a spreadsheet every time a price or quantity changes, one dragged formula and the whole return is wrong.
- Missing the filing deadline because it snuck up between other month-end tasks.
How Retufu handles this
VAT is calculated automatically on every quote, invoice, bill and expense the moment it's captured, at whatever rate you've set, output and input VAT are tracked continuously rather than reconstructed at period-end, and your VAT report is ready whenever you need it, not just when someone remembers to build it.
