VAT registration is one of the most common compliance steps a growing SA business will face. The rules are clear in principle but tripped up by edge cases. This article covers when you must register, when you should consider voluntary registration, what the process looks like, and what changes about your business once you're a registered VAT vendor.
The thresholds
There are two thresholds in SA VAT law.
Mandatory registration: R2.3 million in a 12-month period. From 1 April 2026, registration is compulsory when taxable supplies exceed, or are expected under a written contractual obligation to exceed, R2.3 million in a consecutive 12-month period. You must apply for VAT registration within 21 business days of the turnover crossing (or being expected to cross) the threshold.
Voluntary registration: R120,000. From 1 April 2026, voluntary registration is generally available where taxable supplies exceed R120,000 in the preceding 12 months, subject to the statutory exceptions and alternative tests described by SARS. Some activities may qualify under separate rules even before the threshold is reached.
When voluntary registration makes sense
Voluntary registration is a useful tool but not always the right choice. The case for voluntary registration:
Your customers are mostly VAT-registered businesses. If your customers can claim back VAT on what they pay you, charging VAT doesn't increase the real cost to them. Meanwhile, you can claim back VAT on your own input costs. Net effect: registration is cost-neutral or positive.
You have significant input VAT to claim. If you're investing in equipment, stock, or services that have VAT charged on them, you can claim that VAT back once registered. For capital-intensive startups (e-commerce with stock, manufacturing, equipment-heavy services), this is real cash flow.
Your customers expect VAT compliance as a sign of credibility. Larger customers often filter for VAT-registered suppliers as a proxy for "real business". Registering can unlock these customers.
The case against voluntary registration:
Your customers are consumers (B2C). Consumers can't claim VAT back. If you're not registered, you don't charge VAT, so a registered competitor working to the same net price has to quote 15% more than you do. Voluntary registration directly increases your effective price to your end customer.
You don't have meaningful input VAT. Service businesses with low overheads (consultants, freelancers, online services) often have minimal VAT on inputs. The hassle of two-monthly returns isn't justified.
You're not ready for the admin overhead. VAT registration commits you to monthly or two-monthly returns, careful invoice management, and SARS scrutiny. If your accounting is informal, registration creates risk.
The general heuristic: if you're well below the R2.3 million compulsory threshold, mostly B2C, with modest input VAT, defer registration. If you're B2B, past the R120,000 voluntary threshold, with meaningful input VAT, voluntary registration is usually positive.
The application process
VAT registration is done with SARS, not CIPC. The process:
Step 1: Confirm eligibility. Have your turnover figures ready (last 12 months and forward projection). Confirm you're not in a category that's exempt from VAT under section 12 of the VAT Act (most financial services, educational services by approved providers, residential accommodation, and fare-paying passenger transport by road or rail). Note that medical and health services are not on the section 12 exempt list in South Africa; they are standard-rated.
Step 2: Get your bank account details ready. SARS requires confirmation of a business bank account in the registered name of the entity. The account must be active and able to receive refunds.
Step 3: Submit the VAT 101 application. This is done online via SARS eFiling (if you have an existing tax profile) or by attending a SARS branch by appointment. The form requires details about the business, expected turnover, supplies you make, and your bank account.
Step 4: SARS review. SARS reviews the application. For voluntary registrations and registrations close to the threshold, SARS may request additional supporting documentation: invoices showing turnover, bank statements, proof of business activity, lease agreements, and so on. SARS is increasingly cautious about voluntary registration applications because of historical fraud.
Step 5: Identity verification. SARS does not require a branch visit for a standard VAT registration. The application is made through eFiling, or through a virtual appointment booked on the SARS eBooking system. On submitting the application you may be required to complete a facial biometric authentication step. If that verification fails, SARS automatically creates a verification case and may request supporting documents. A branch appointment is needed only in narrower cases, for example where a compulsory registration has to be backdated more than six months from the date the threshold was exceeded, or where you cannot complete the biometric step. The applicant must be the registered representative, typically the public officer of a company, or the sole proprietor.
Step 6: Approval and VAT vendor number. Once approved, SARS issues a VAT vendor number (in the format 4XXXXXXXXX). You're now a registered VAT vendor and must charge VAT on supplies from the effective date of registration.
Realistic timeline: SARS states that where no risk is identified on the application, it issues the VAT reference number immediately. Where the application is selected for validation, SARS sends a Registration Application Review Notice and you have 21 business days to supply the supporting documents, after which the case must still be worked, so a flagged application takes substantially longer. Voluntary registrations and registrations with thin trading evidence are the ones most often flagged.
What changes after registration
Once registered as a VAT vendor, your business operations change in several ways:
You charge VAT on your supplies. The current VAT rate in SA is 15%. You charge this on top of your selling price (B2B context) or include it in your selling price (B2C context). Either way, the 15% belongs to SARS, not to you.
You can claim input VAT. When you buy goods or services from other VAT vendors and they charge you VAT, you can claim that VAT back from SARS. This is the major benefit.
You issue tax invoices, not just invoices. A tax invoice has prescribed information: your VAT number, the recipient's VAT number (if applicable), the description of goods/services, the VAT rate, the VAT amount, the total. Failure to issue valid tax invoices is a compliance issue and prevents your customers from claiming their input VAT.
You file VAT returns. Most SMEs file every two months, in Category A or Category B depending on which two-month cycle SARS allocates. Category A periods end on the last day of January, March, May, July, September and November; Category B periods end on the last day of February, April, June, August, October and December. Vendors whose taxable supplies exceed or are likely to exceed R30 million in any consecutive 12-month period file monthly (Category C). The return reports your output VAT (what you charged customers), your input VAT (what suppliers charged you), and the net difference owed to or from SARS. The first VAT return after registration is often the largest because you can claim accumulated input VAT on stock and assets held at registration date.
You keep VAT records. All tax invoices, both issued and received, must be kept for 5 years. You also keep ledgers showing your VAT calculations.
You pay VAT differences to SARS, on time. Late filing or late payment attracts penalties (10% on the unpaid VAT) and interest. Repeated late payment triggers SARS scrutiny.
VAT in the broader business context
A few things to understand about VAT registration that aren't always obvious:
VAT registration affects your pricing strategy. If you were charging R1,000 unregistered, you're now charging R1,150 to keep the same net price (R1,000 + R150 VAT). Your customers will notice. Plan the transition.
VAT can be claimed on stock and capital assets at registration. If you have stock worth R200,000 with VAT included (R200,000 ÷ 1.15 = R173,913 net + R26,087 VAT), you can claim that R26,087 in your first VAT return. Same for capital equipment. Document carefully.
Some supplies are zero-rated, not standard-rated. Exports, certain goods supplied to farmers under the agricultural zero-rating, brown bread, maize meal, milk, eggs, fresh fruit and vegetables, and a few other categories are zero-rated. You don't charge VAT on these but you can still claim input VAT. This is favourable.
Some supplies are exempt, not zero-rated. Financial services (in most cases), residential rental, education by approved providers, and certain other services are exempt. You don't charge VAT and you cannot claim input VAT on costs related to exempt supplies. This is unfavourable.
Imports attract VAT at the border. When you import goods, VAT is charged at the border based on the customs value. If you're a registered vendor, this is claimable as input VAT. If not, it's a sunk cost.
Mistakes that delay registration
Inadequate proof of business activity. SARS wants to see real trading. Three invoices, one bank deposit, and a brochure aren't enough. Provide a year of trading evidence where possible.
Inactive bank account. SARS confirms the bank account before approving. A new account with no transactions is suspicious.
Wrong industry classification. SARS requires an industry classification that matches your actual activity. Mismatches trigger rejections.
Incorrect public officer / representative. The application must be signed by the legally authorised representative. For companies, this is the Public Officer (typically the senior director). For sole proprietors, it must be the sole proprietor in person.
Voluntary registration when business activity is minimal. SARS is wary of voluntary registrations from businesses that haven't yet started trading, because of historical VAT refund fraud. If you're applying voluntarily, your application needs to demonstrate genuine ongoing trade.
Cost of registration
SARS does not charge a fee for VAT registration. Our service fee for handling the registration is R2,990, which includes preparing the application, gathering and verifying documents, submitting via eFiling and following up until the VAT number is issued.
If you're already registered for income tax with SARS and have an active tax profile, you can attempt the registration yourself. The complexity is usually around the SARS branch interaction and supporting documentation; that's where most applicants stumble.
VAT registration is one of those compliance steps that's straightforward in theory but trips up businesses on the practical execution. If you want it handled, it's a service we offer alongside CIPC registration or standalone. Either way, the goal is the same: get registered cleanly, stay compliant, claim what you're owed, and move on with running your business.
