Frequently Asked Questions

Who needs a South Africa VAT number?
Any business that supplies taxable goods or services in South Africa and whose taxable turnover exceeds ZAR 1 million per year must register for VAT with SARS. Voluntary registration is also possible below that threshold. Verifying a supplier's VAT number before transacting is essential for reclaiming input VAT. Lookuptax makes this check instant — try it free.
Is VAT number validation mandatory for invoices in South Africa?
Yes. South African tax law requires that a valid VAT registration number appear on every tax invoice for transactions above ZAR 5,000. Including an invalid or unregistered VAT number invalidates the invoice and removes the buyer's right to claim input VAT. Automate this check with the Lookuptax API — sign up free.
What if a South Africa VAT number is invalid or inactive?
An invalid or deregistered VAT number means the supplier is not entitled to charge VAT, and the buyer cannot claim an input tax deduction. SARS penalties may apply to both parties. Lookuptax flags invalid and inactive numbers in real time so you can resolve issues before payment. Sign up free to start validating.
