It's one of the most-asked questions by tradesmen growing a business: when do I have to register for VAT, and should I do it early? Here's the straight answer for South Africa.
Compulsory registration: the R1 million line
You must register for VAT once your taxable turnover exceeds R1 million in any consecutive 12-month period. "Turnover" means your total sales — not your profit. You also have to register if you sign a written contract that you know will push you over R1 million in the next 12 months.
Once you cross that line, registration isn't optional and SARS expects you to do it promptly. Miss it and you can be liable for the VAT you should have charged, plus penalties.
Watch your rolling 12 months, not your tax year. The R1m test looks at any consecutive 12-month window. A few big jobs in a row can take you over without you noticing.
Voluntary registration: from R50,000
You may register voluntarily once your taxable turnover has passed R50,000 in the previous 12 months. Some growing businesses do this on purpose. Why? Because once you're registered you can claim back the VAT on what you buy — materials, tools, fuel, that bakkie service.
The real question: should you register early?
This is where tradies get it wrong in both directions. It comes down to who your customers are:
- Mostly homeowners? They can't claim VAT back, so registering makes your price 15% higher to them overnight — you become more expensive than the unregistered guy down the road. Usually best to wait until you must.
- Mostly businesses, body corporates, contractors? They claim the VAT back, so your 15% costs them nothing — and you get to claim input VAT on all your materials. Registering early can genuinely pay.
Registered or not, BlitzBooks handles it — flip VAT on and every invoice shows 15% correctly.

- You charge 15% VAT on your work and issue proper tax invoices (see what must be on a tax invoice).
- You file VAT201 returns (usually every two months) and pay over the VAT you've collected, less the input VAT you've claimed.
- You need to keep clean records of every invoice in and out — this is where good software stops being optional.
