Should I Register for VAT? The Economics, Not Just the Threshold (South Africa)

It depends on three things, and turnover is not really one of them. First, how much of what you spend carries VAT: you get that back once registered, so a retailer buying stock recovers far more than a consultancy whose costs are mostly salaries. Second, and usually decisive, who your customers are: if they are VAT-registered businesses they claim your VAT straight back and never feel it, but if they are private consumers your prices effectively rise 15% or your margin absorbs it. Third, the compliance cost of six VAT201 returns a year. The calculator on this page puts a rand figure on all three and tells you whether registering leaves you better or worse off.

15/115 of what you spend on VATable costs, not 15% of it. This trips up almost everyone. Because you are not registered, the prices you pay today already include VAT, so the VAT is inside the price rather than added on top. R115,000 of VATable costs returns R15,000, not R17,250. Getting this backwards overstates the case for registering by 15% every single time. Note too that not all costs carry VAT at all: salaries and wages, interest and bank charges on credit, petrol and diesel, municipal rates and residential rent carry none, so a business whose costs are mostly staff recovers very little.

Almost always, yes, and this is the single most decision-relevant fact about VAT registration. A VAT-registered business customer claims back every rand of VAT you charge them, so your price with 15% added costs them exactly what it costs them today. The 15% is invisible to them. That means you can pass the full amount on, keep your own revenue completely intact, and still reclaim the VAT on your own costs, which is pure gain. If instead you sell to private consumers or to small businesses that are not registered, they cannot reclaim anything, so you either raise your prices 15% and become less competitive against an unregistered rival, or you hold your price and take the hit on margin.

Either your customers pay about 15% more, or you absorb it and lose 15/115 of your revenue on those sales, roughly 13%, or some split of the two. On R900,000 of consumer sales, absorbing the whole amount costs about R117,400 a year in revenue you simply stop receiving. That is why a consumer-facing business with few VATable costs is usually better off staying unregistered until the law forces the issue. The calculator works out your break-even pass-through, the exact share of the VAT you could absorb while still being no worse off than staying unregistered.

From 1 April 2026, registration is compulsory once your taxable supplies exceed R2.3 million in any consecutive 12-month period, raised from the long-standing R1 million. You must apply within 21 business days of crossing it. Voluntary registration is open from R120,000 of taxable supplies in the preceding 12 months, raised from R50,000. Below R120,000 you can still qualify in specific cases, for example if you have already made more than R4,200 in a single month, or averaged more than R4,200 a month over the months you have traded, or hold written contracts, finance or funding that will take you past R120,000 within 12 months. The VAT rate itself remains 15%, the increases to 15.5% and 16% announced in 2025 were reversed.

You may, but check the exit bill first. When the threshold rose from R1 million to R2.3 million on 1 April 2026, a large number of vendors became free to cancel their registration by submitting a VAT123e to SARS. The catch is section 8(2): on the day you stop being a vendor, every enterprise asset you still hold is deemed to have been supplied back to you, valued under section 10(5) at the lower of what it cost you or its open market value, and you account for output VAT of 15/115 on that amount. On R230,000 of stock and equipment that is a R30,000 bill in your final tax period. Assets on which input tax was denied in the first place, motor cars and entertainment, are excluded. Switch this page's calculator to deregistration mode and it works out both the annual saving and how many months the exit VAT takes to earn back.

Only if you are a natural person. This is the most under-explained rule in South African VAT. On the default invoice basis you owe SARS the VAT as soon as you raise an invoice, whether or not you have been paid, so a slow-paying debtor book means you finance SARS as well as your customer. The payments basis removes that entirely, but SARS restricts it to sole proprietors and partnerships made up only of natural persons, with taxable supplies under R2.5 million on both a backward and forward-looking test, plus a short list of public authorities, municipalities and welfare organisations. The VAT 404 guide states it plainly: juristic persons, meaning companies and close corporations, and trust funds do not qualify. If you trade through a Pty Ltd, the invoice basis is your only option at any turnover. Note the trade-off is symmetric: on the payments basis you also only claim input VAT once you have actually paid your own suppliers.

Less than people assume, and sometimes it helps. The VAT cycle has real float built into it: with a two-month tax period and payment due by the 25th of the following month, a sale made at an average point in the period gives you roughly 55 days before the VAT has to reach SARS. If your customers pay faster than that, you are holding their VAT in your account in the meantime, which is a genuine if temporary benefit. The drag only starts when your debtor days run past that float. On R1 million of standard-rated sales, which carries R150,000 of output VAT, customers who take 90 days to pay leave roughly R14,000 of your cash permanently out funding SARS ahead of your own debtors.

Input tax is denied outright on several things even when they are genuine business expenses. Motor cars are the big one: you cannot claim the VAT on buying a car, no matter how business-critical, unless you are a motor dealer or a car rental business. Entertainment is the other, and it is broader than people expect, covering client lunches, year-end functions, venue hire, staff refreshments and free or subsidised staff meals. Also denied are club, sporting and social society subscriptions, and goods or services acquired by medical schemes for benefit cover. Leave all of these out when you estimate what share of your costs carries recoverable VAT.

Yes, essentially always, and this is the clearest case in the whole decision. Zero-rated supplies carry no output VAT, so you charge your customers nothing extra, but you still reclaim all the VAT on what you bought. That puts you in a permanent refund position where SARS pays you rather than the other way round. Zero-rated supplies include exports, basic foodstuffs such as brown bread, maize meal, rice, fresh fruit and vegetables, dried beans and eggs, and fuel levy goods such as petrol and diesel. Two practical notes: SARS must pay a valid refund within 21 business days or owe you interest, but refund returns are also the most likely to be selected for verification, so keep your tax invoices in order.

Most vendors are placed in Category A or Category B and file a VAT201 every two months, so six returns a year, differing only in which months the periods end. Category C is monthly and is compulsory once taxable supplies exceed R30 million in any 12 months, or where a vendor asks for it or SARS imposes it for repeated non-compliance. Category D is six-monthly and is mainly for farming operations with taxable supplies under R1.5 million. Category E is annual and applies to certain companies and trusts letting property or renting goods to connected persons. Payment is due by the 25th of the month following the period, or the last business day of that month if you file and pay through eFiling.

Sometimes, and this is the one thing the calculator on this page deliberately cannot price for you. Many larger companies and government departments will not deal with a supplier who cannot issue a valid tax invoice, because it costs them the input VAT on everything they buy from you. If a specific contract or customer relationship depends on it, that can justify registering even when the pure arithmetic says otherwise. Treat that as a commercial decision made with your eyes open about the annual cost, which the calculator does give you, rather than a vague belief that being registered makes a business look more credible.

The advantages: you reclaim the VAT on your purchases, which matters most when your costs are stock, materials or equipment rather than salaries; you can claim a one-off amount on equipment bought after registering; some larger clients and government departments will only deal with suppliers who can issue a valid tax invoice, since otherwise they lose the input VAT on everything they buy from you; and a zero-rated supplier ends up receiving refunds rather than paying. The disadvantages: six VAT201 returns a year plus the record keeping; an effective 15% price rise for any customer who cannot reclaim it, or the same amount off your margin if you absorb it; and on the invoice basis you owe SARS the VAT when you invoice rather than when you are paid. Which side wins is not a matter of opinion, it depends on your cost base and your customer mix, which is what the calculator on this page works out.

Registration is done on eFiling using a VAT101 application, and you need an income tax reference number for the business first. SARS asks for supporting documents including proof of business address, a bank confirmation letter or recent statements in the business's name, ID copies for the directors or members, the CIPC registration certificate for a company or close corporation, and proof of the taxable supplies you are relying on, meaning invoices, contracts or projections. Because of a rise in fraudulent applications SARS now validates registrations before issuing a VAT number, so watch your eFiling correspondence for a Registration Application Review Notice, which gives you 21 days to supply what it asks for. If registration is compulsory you must apply within 21 business days of crossing R2.3 million. Check the current requirements on the SARS website before applying, as the document list does change.

You apply in writing using form VAT123e to cancel all your enterprises, or VAT123T to cancel a separately registered branch or enterprise, stating the circumstances for the cancellation. You can qualify once your taxable supplies will be under R2.3 million in any consecutive 12 months. Two things matter more than the form. First, you must keep charging and declaring VAT, and keep claiming input tax, right up to the last day of the final tax period SARS specifies, not from the day you send the form. Second, the output tax on assets you still hold is declared in your final return, in field 1A. SARS does not publish a processing time, and it cannot finalise a cancellation until every outstanding VAT liability and obligation has been settled, so leaving is not instant and a clean compliance record makes it faster.

No. This is a free planning tool using simplified assumptions: one blended VATable share across all your costs, an estimated pass-through decision, and an average debtor-days figure rather than your actual ledgers. It does not model mixed taxable and exempt supplies needing apportionment, second-hand goods notional input tax, imports, or the once-off input claim on stock you already hold at registration. VAT is one of the more technical taxes and the penalties for getting registration timing wrong are real, so confirm your own position with SARS or a registered tax practitioner before acting.
