Frequently Asked Questions​

What is the format of a South African VAT registration number?​

A South African VAT registration number is a 10-digit number always starting with 4 (e.g. 4480152117). The first digit 4 identifies it as a VAT registration. There is no alphabetic country prefix and no publicly documented checksum — format validation is limited to confirming 10 digits starting with 4. Verify VAT numbers on the SARS eFiling vendor search for authoritative confirmation. [1]

What is South Africa's VAT registration threshold and vendor categories?​

South Africa's VAT rate is 15% (increased from 14% on 1 April 2018). Registration thresholds: Compulsory — taxable supplies exceed ZAR 2,300,000 in any consecutive 12-month period (raised from ZAR 1,000,000 with effect from 1 April 2026); Voluntary — taxable supplies have exceeded ZAR 120,000 in the past 12 months (raised from ZAR 50,000 on the same date). Vendor categories: Categories A and B file two-monthly on alternating cycles; Category C files monthly, and applies where taxable supplies exceed ZAR 30 million in a 12-month period; Category D is six-monthly for qualifying farming enterprises; Category E is annual. [1]

The SARS vendor search shows an "Office" field — what does it indicate?​

The Office field indicates which SARS regional office administers the vendor's account. It does not affect VAT registration validity — a VAT number is valid nationally regardless of which regional office manages it. The office is useful for directing correspondence or audit inquiries to the correct SARS location but can be ignored for standard input tax verification. [1]

Can I claim input tax credits on invoices from a supplier whose VAT number I have not verified?​

Under the VAT Act (89 of 1991), input tax may only be deducted on a valid tax invoice from a registered vendor. An invalid or unverifiable VAT number means SARS may disallow the ITC during audit. The burden of proof falls on the claimant. SARS recommends verifying VAT numbers on the eFiling vendor search — keep a dated printout or screenshot as audit documentation. [1]

My supplier deregistered from VAT — what happens to invoices before and after deregistration?​

Before deregistration: invoices with a valid VAT number are valid tax invoices for ITC. After deregistration: the vendor cannot charge VAT or issue tax invoices; their VAT number is removed from the SARS vendor search. If discovered mid-relationship, verify the deregistration date and reverse any ITC claimed on post-deregistration invoices to avoid SARS disallowance. [1]

What are the mandatory fields on a South African tax invoice for input tax claims?​

A full tax invoice (for supplies over ZAR 5,000 including VAT) must contain: (1) "Tax Invoice"; (2) Supplier name, address, and VAT number; (3) Recipient name, address, and VAT number (B2B); (4) Unique sequential invoice number; (5) Issue date; (6) Description of goods/services; (7) Quantity/volume; (8) Unit price excluding VAT; (9) VAT amount; (10) Total including VAT. Abridged invoices (ZAR 50–5,000) only need items 1, 2, 4–6, 9, 10. [1]

Does South Africa have VAT rules for non-resident digital service providers?​

Yes. Non-resident suppliers of electronic services (streaming, SaaS, apps, digital content) must register for South African VAT if supplies to South African recipients exceed ZAR 2,300,000 in any consecutive 12-month period — raised from ZAR 1,000,000 with effect from 1 April 2026. The e-services regime itself has applied since 1 June 2014. Registered foreign e-service providers submit monthly VAT returns via SARS eFiling. Their VAT numbers are verifiable on the SARS vendor search like domestic vendors. [1]
