Heads up: South Africa’s VAT rate is increasing for the first time in 7 years. Effective 1 May 2025, the standard VAT will go from 15% to 15.5%. While a half-percent change might sound trivial, it affects every VAT transaction going forward – which means as a bookkeeper you need to be prepared. This quick guide cuts the fluff and tells you exactly what’s changing and what to do about it:
● What’s changing? From 1 May 2025, any sale of goods or services that was subject to 15% VAT will now carry 15.5% VAT. The government announced this in the 2025 Budget, aiming to boost revenue. Another similar hike (to a 16% VAT rate) is on
the horizon for April 2026, but for now our focus is on the 15.5% rate in 2025. This is the first VAT increase since 2018. so we haven’t dealt with a change like this in a while. It’s crucial to get it right.
● Who is affected? All VAT-registered businesses and their customers. If you do bookkeeping for a VAT-registered entity, this change 100% applies to you. It doesn’t matter if your client is a small corner shop or a large company – when they charge VAT on sales or pay VAT on expenses, it will be at 15.5% going forward. Consumers will pay a tad more on their purchases (the VAT portion of prices will be higher), and businesses not registered for VAT will also feel a slight squeeze on costs because they can’t claim this extra VAT back. As a bookkeeper, you’ll be the one implementing and monitoring this change in the accounts.
● When does it start? 1 May 2025 is the go-live date. The timing is strict – the new rate applies based on the invoice or payment date. In bookkeeping terms, that’s the time-of-supply rule: whichever comes first between issuing an invoice or receiving payment determines the VAT rate. So if an invoice is dated 30 April, it’s 15% VAT, even if the goods are delivered in May. If an invoice is dated 1 May or later (or payment comes in after 1 May without an invoice), 15.5% applies. Mark this date clearly on your calendar and in your accounting system.
Now that we’ve covered the basics, let’s look at what you should do to get your books and systems ready.
Why This Matters and Key To-Dos for Bookkeepers
Even a small rate change can lead to big headaches if not handled properly. As the “busy bookkeeper” in charge, you’ll want to avoid scenarios like clients undercharging VAT, misstating returns, or quarrelling with customers over a few cents. Here are the key implications and tasks:
1. Update Accounting Software and Templates
Go into your bookkeeping or ERP software before 1 May and update the VAT rate settings. Most systems will allow you to add a new 15.5% tax code (or update the existing standard VAT code with the new rate effective from a date). Do a test by creating an invoice dated in May to ensure it calculates VAT at 15.5% not 15%. Likewise, update any invoice templates
or POS systems your clients use. Don’t overlook things like Excel formulas: if your spreadsheet quotes or working papers have hardcoded 15% (or use 15/115 for VAT fraction), change those to 15.5/115.5 going forward. A quick test now prevents errors later. A great accounting system like Sage Business Cloud Accounting would automatically apply the VAT rate increase.
2. Check Pricing and Communicate
Advise your clients to review their pricing. They should decide whether to increase their prices to account for the 0.5% higher VAT. Most will simply pass it on to customers (keeping the pre-VAT price the same). For example, an item that was R100 + 15% VAT = R115 will likely become R100 + 15.5% = R115.50. It’s a tiny increase per item, but across many sales
it adds up. Make sure all displayed or advertised prices include VAT at the new rate. If re-stickering products by 1 May is impractical, your client can post a visible notice at the store entrance and checkout saying prices will be adjusted at the register to include the new 15.5% VAT. (This is a SARS-approved workaround until August 2025, but ideally prices on
shelves should be updated sooner than later.) Help draft a short communication to customers if needed – e.g. a signage or an email/newsletter note that “VAT is increasing, which will reflect in our pricing from May 1.” Clarity keeps customers informed and avoids confusion at checkout.or POS systems your clients use. Don’t overlook things like Excel formulas: if your spreadsheet quotes or working papers have hardcoded 15% (or use 15/115 for VAT fraction), change those to 15.5/115.5 going forward. A quick test now prevents errors later.
3. Review Contracts and Quotes
Scan any existing contracts, service agreements, or long-term quotes your client has issued. You’re looking for any clause about pricing being fixed inclusive of VAT. If an agreement doesn’t allow price changes for a VAT increase, flag it – the client might have to absorb the cost or renegotiate that contract. For any quotes given to customers that haven’t yet been invoiced or accepted, ensure the client knows those may need updating. It might even be wise to remind clients: if they want to secure business before the hike, closing deals (and invoicing) by 30 April means the customer only pays 15% VAT – a possible selling point in April. Post-1 May, the quote amounts may go up slightly due to VAT. This kind of proactive client service not only ensures no one is caught off guard, it shows you’re thinking ahead for their benefit.it adds up. Make sure all displayed or advertised prices include VAT at the new rate. If re-stickering products by 1 May is impractical, your client can post a visible notice at the store entrance and checkout saying prices will be adjusted at the register to include the new 15.5% VAT. (This is a SARS-approved workaround until August 2025, but ideally prices on shelves should be updated sooner than later.) Help draft a short communication to customers if needed – e.g. a signage or an email/newsletter note that “VAT is increasing, which will reflect in our pricing from May 1.” Clarity keeps customers informed and avoids confusion at checkout or POS systems your clients use. Don’t overlook things like Excel formulas: if your spreadsheet quotes or working papers have hardcoded 15% (or use 15/115 for VAT fraction), change those to 15.5/115.5 going forward. A quick test now prevents errors later.
4. Educate and Coordinate
Make sure everyone involved in the sales or billing process on your client’s side is aware of the new rate. As the bookkeeper, you might prepare a one-page cheat sheet for your client’s team: key points about 15.5% VAT from 1 May, what to do if a customer asks about it, and to always use the correct rate on invoices after that date. If your client’s business issues
manual invoices or uses multiple systems (like an invoicing app plus a separate stock system), check all points for consistency. One overlooked setting could mean some invoices still go out showing 15% – which is a problem. So double-check those with the team. It’s also wise to be on standby in early May for any questions or issues that pop up.
5. Monitor the Transition Closely
When May 1 arrives, pay extra attention to transactions around that date. For April 2025 month-end, you might have late invoices or credit notes. Remember: a credit note for a sale made in April must use 15% (the original rate) even if issued in May. And a May sale’s credit note should use 15.5%. Set up a mental (or software) check: if an invoice date is April 30 or earlier, it should carry 15% VAT; if it’s May 1 or later, 15.5%. Correct any mistakes promptly. If you find out in June that someone forgot to charge the extra 0.5% in May, the client might owe SARS that difference out of pocket. Better to catch it immediately. Encourage clients to settle any borderline cases properly – e.g. if a project spans April and May, consider issuing two invoices (one up to April 30 at 15%, and one from May 1 at 15.5%) to perfectly separate the tax treatment. It’s a cleaner approach that SARS actually anticipates in their guidelines.
6. Adjust VAT Returns and Records
When it’s time to do the VAT return for May (or the bi-monthly April–May period), ensure the figures incorporate the new rate. You don’t need to file anything extra – the normal VAT201 return will accommodate the 15.5% calculations. Just be careful if your reporting period straddles the change. It might be wise to keep a note of how much sales were at 15%
vs 15.5%, in case of queries. Also, update any internal checklists: for example, if you reconcile VAT by taking total sales*15/115, that formula changes for May sales to *15.5/115.5. SARS’s eFiling should automatically handle the new rate for declarations, but your own workpapers need updating to avoid under/over-stating anything.
7. Stay Informed
Make use of the resources provided by SARS and professional bodies. SARS has an FAQ document and a pocket guide detailing the nitty-gritty of the VAT change. If something unusual comes up (like a complicated lay-by sale or a mixed-rate invoice issue), those guides can be a lifesaver. Also keep an eye out for any updates – for instance, if Parliament delays or alters the plan (currently it’s expected to go through as announced). According to National Treasury, the hike will be effective May 1 even if the budget isn’t formally passed by that date, so we’re operating on that assumption. But any further official communication will be on SARS’s website. As a busy bookkeeper, you don’t have time for surprises, so a quick news scan or subscription to a tax news service around that time can keep you alerted.vs 15.5%, in case of queries. Also, update any internal checklists: for example, if you reconcile VAT by taking total sales*15/115, that formula changes for May sales to *15.5/115.5. SARS’s eFiling should automatically handle the new rate for declarations, but your own workpapers need updating to avoid under/over-stating anything.
Bottom Line
Your role as a bookkeeper is mission-critical in this VAT rate transition. Attention to detail and proactive steps now will save your clients money and hassle after May 1. To recap the essentials: update all systems to 15.5%, adjust prices or use notices, review contracts, educate the team, and double-check everything in early May. The change from 15% to 15.5% may be small in number, but it touches countless daily transactions – getting it wrong could result in compliance issues or lost revenue. The good news is, with proper preparation, it should be a smooth shift. Many of us successfully navigated the last increase in 2018, and we can do it again. Once the new rate is in place and your processes are adjusted, it’ll be back to business as usual – until the next 0.5% hike in 2026. By staying on top of this one, you’re not only helping your clients comply, but also demonstrating the value of a diligent bookkeeper. So take a moment now (yes, amidst all your other work!) to run through the checklist. Come 1 May 2025, you’ll be glad you did, and your clients will sail through the VAT change with confidence and accurate books. Remember: even a 0.5% change can cause confusion if left unaddressed. But with this guide and some focused effort, you’ve got this covered.
Happy bookkeeping, and here’s to a smooth VAT transition!
