VAT & Tax Implications in Cross-Border Credit
? 8 min read 11 questions answered
Extending credit to a customer in another country brings VAT and tax exposure that domestic deals don't have. This article answers the questions credit teams ask most often about zero-rating, withholding tax, local registration, and what changes when a foreign debtor defaults - based on our Credit Thursdays session below.

Zero-Rating & Export Sales
Q1: Why is VAT different when I extend credit to a customer in another country?
Cross-border deals shift three things at once: the VAT treatment of the sale itself (export sales can qualify for zero-rating), a separate withholding tax exposure on certain cross-border payments, and the VAT mechanics of a default, which don't work the same way once the debtor is offshore. Getting any one of these wrong turns a credit risk into an unplanned tax liability.
Q2: What is zero-rating, and how do I qualify for it on an export sale?
Goods physically exported from South Africa can be zero-rated for VAT (charged at 0% instead of the standard rate) - but this is a relief you have to earn with proof, not something you can assume applies automatically.
What to do:
- Confirm who is arranging and paying for transport - your business (direct export) or the customer (indirect export, which carries a stricter documentary burden).
- Build the shipping arrangement into the credit application, not as an afterthought.
- Confirm the exact documentation needed with finance before terms are approved - see Q3.
⚠ Note: If the required proof isn't obtained and kept, SARS can deny the zero-rating and raise output VAT at the standard rate - often with penalties and interest - well after the goods have shipped and the money's gone out the door.
Q3: What documentation do I need to support a zero-rated export sale?
SARS expects a complete file for every shipment you extend credit against, not documents chased down after the fact.
What to do - confirm this file exists for every shipment:
- Export invoice matching what actually shipped.
- Proof of physical export (customs clearance / bill of entry) plus transport documents.
- Bill of lading, airway bill, or road manifest showing the goods left South African borders.
- Proof of payment received from the foreign customer.
- Contract or order confirming the export terms, especially who arranged and paid for transport.
Q4: Does export zero-rating still apply if my "foreign" customer has a local registration in South Africa?
Not automatically. A customer can be foreign-owned but still registered as a VAT vendor here, or trading through a local branch or subsidiary. In that case, the sale is generally a domestic supply for VAT purposes, standard-rated, even though the parent company sits offshore. Ask whether the customer is VAT-registered in South Africa or trading through a local entity at onboarding - not just what country their head office is in.
Reciprocity & International VAT Rules
Q5: What is reciprocity, and why does it matter for costs incurred abroad?
Reciprocity is when a country will only refund VAT to a foreign business if that business's home country offers the same courtesy back. South Africa has no broad scheme of its own for refunding VAT to foreign businesses on services, so South African businesses often can't claim reciprocity abroad. In practice, VAT paid on costs incurred in another country - sending staff, attending a trade show, paying a local supplier - can become a straight, unrecoverable cost that needs to be priced into the deal.
ⓘ Tip: Reciprocity positions vary by country and change over time - always confirm the current position for the specific country with finance before pricing it into a deal.
Q6: What are the 6th, 8th and 13th VAT Directives?
These are European Union rules, not South African law - useful to recognise if you deal with EU customers or EU costs. The 6th Directive was the original EU law that harmonised VAT rules across member states (now largely historical). The 8th Directive governs VAT refund claims between EU member states only. The 13th Directive is the one that matters to a South African business - it governs how a business established outside the EU reclaims VAT paid in an EU country, and it's the one where reciprocity conditions (see Q5) can apply.
Withholding Tax
Q7: What is withholding tax, and when does it apply to a cross-border deal?
Withholding tax is deducted at source from certain payments made to a person or business outside South Africa, before the money reaches them. It's a completely separate tax to VAT and can apply regardless of your VAT position.
Common triggers:
- Cross-border interest paid to a foreign lender or on foreign-funded credit lines.
- Royalties for intellectual property, licences, or franchise rights across a border.
- Certain cross-border service fees paid to a foreign person or entity.
- Dividends to foreign shareholders in group financing structures.
Q8: Who is liable for withholding tax - us or the foreign customer?
In most structures, it's the South African party making the payment who carries the obligation to withhold the tax and pay it over - not the foreign recipient. If tax should have been withheld and wasn't, the South African payer can be held liable for the shortfall, plus penalties and interest, even though the money has already gone offshore.
⚠ Note: A Double Taxation Agreement (DTA) between South Africa and the customer's country can reduce or eliminate the rate - this needs a tax specialist's eyes on the specific DTA, not a guess.
Default, Write-Off & Best Practice
Q9: What happens to VAT if a foreign customer defaults or is written off?
It's not the same VAT event as a domestic write-off. On a domestic bad debt, VAT was charged and paid over on the original sale, so a bad debt relief mechanism lets you claim it back on the unpaid portion. On a cross-border default, the original export sale was likely zero-rated, meaning little or no VAT was ever paid over - so there may be little or nothing to claim back. The loss can be a straight credit loss on the full value, without the VAT cushion a domestic write-off provides. The exact mechanics depend on how the original sale was treated, so confirm with finance case by case.
Q10: What common mistakes trigger SARS queries on export credit?
Every mistake we see traces back to a paperwork or process gap - which means every one is preventable at credit application stage.
Watch out for:
- Missing or incomplete export proof backing a zero-rating claim.
- Treating an indirect export like a direct one (the documentary burden is higher when the customer arranges transport).
- No withholding tax review before a cross-border payment goes out.
- Mismatched invoice and shipping detail.
- Writing off cross-border debt using domestic bad debt logic.
- No paper trail on the credit terms and shipping arrangements actually agreed.
Q11: What should I confirm with finance before extending cross-border credit terms?
Run these six questions with finance before terms are approved - none of them require you to become a tax expert, just to know when to ask.
What to do:
- Who is arranging and paying for transport - us or the customer?
- What VAT treatment will apply, and what documentation will we need?
- Are any payments flowing the other way (to a foreign supplier, licensor, or lender) that could trigger withholding tax?
- Does a Double Taxation Agreement exist with this customer's country?
- If this customer defaults, what VAT (if any) would be recoverable?
- Is there a documented paper trail supporting the tax position we're relying on?
