Selling products online to customers in other countries is one of the most exciting opportunities available to UK small businesses today. But once your orders start crossing borders, so does your VAT complexity. Get it wrong and you risk fines, delayed shipments, and some very unhappy customers hit with unexpected import charges at their door. Get it right, and you can scale internationally without the compliance headaches.
Since Brexit, the rules have shifted considerably. The UK now sits outside both the EU VAT area and the EU's digital services frameworks, which means UK businesses selling to EU consumers — and vice versa — must navigate two entirely separate sets of rules. This guide cuts through the confusion and gives you a clear, practical picture of your obligations.
Understanding the Post-Brexit VAT Landscape
Before 1 January 2021, UK businesses selling goods to EU consumers benefited from distance selling thresholds — you only had to register for VAT in another EU country once your sales there exceeded a certain value. Those days are gone.
Under the current rules, the UK is treated as a third country by the EU. This has two major implications. First, goods you export from the UK to EU customers are zero-rated for UK VAT — you don't charge UK VAT on these sales. Second, your EU customers (or your business, depending on how you structure fulfilment) may owe import VAT and customs duties at the point the goods enter the EU. Who bears that cost — and how it's collected — depends on whether you sell on Delivered Duty Paid (DDP) or Delivered Duty Unpaid (DDU) terms.
Many UK sellers learned this the hard way in early 2021, when EU customers started refusing parcels because of unexpected customs bills. If you're shipping directly to EU consumers, it's worth considering DDP terms so that all taxes are paid upfront and the customer receives a clean, surprise-free delivery.
The EU's One Stop Shop (OSS) and Import One Stop Shop (IOSS)
To simplify VAT compliance for businesses selling into the EU, the European Union introduced two schemes in July 2021: the One Stop Shop (OSS) and the Import One Stop Shop (IOSS).
OSS is designed for businesses already established in an EU member state who sell goods or digital services to consumers across multiple EU countries. As a UK business, you generally cannot register for OSS directly — but if you hold stock in an EU fulfilment centre (for example, through Amazon FBA warehouses in Germany or France), you may be required to register for VAT in that country and could potentially use OSS from there.
IOSS is more directly relevant to many UK e-commerce sellers. It applies to the sale of goods imported from outside the EU — including the UK — with a value of £135 or less (€150 or less). If you register for IOSS through an EU member state (or via an intermediary, which is required for non-EU businesses), you collect VAT at the point of sale at the destination country's rate, declare it monthly through a single IOSS return, and the goods pass through EU customs without further VAT being collected. This creates a far smoother experience for your EU customers.
IOSS registration for a UK business requires appointing an EU-based intermediary — a tax representative who is jointly liable for VAT accuracy. Several UK accountancy firms and specialist VAT agents offer this service. It's an added cost, but for businesses with meaningful EU sales volumes, it typically pays for itself in reduced cart abandonment and customer complaints.
Selling Digital Services to EU and Global Consumers
If your e-commerce business sells digital products — software, e-books, online courses, music downloads, or subscription services — the rules differ again. For sales to EU consumers, VAT is due in the customer's country at their local rate, regardless of the value of the transaction. There is no minimum threshold.
UK businesses selling digital services to EU consumers must therefore either register for VAT in each EU country where they have customers, or register for the EU's non-Union OSS scheme. The non-Union OSS allows you to register in a single EU member state and file one quarterly return covering all EU sales — a far more practical option. Ireland is a popular choice for UK businesses given the shared language and close business ties.
For sales to consumers in other countries — the US, Canada, Australia, for instance — you'll need to check each jurisdiction's rules individually. Australia introduced its GST on digital services in 2017; the US has a patchwork of state-level sales tax rules. This is where working with a VAT-specialist accountant, or using a platform that can model your international tax exposure, becomes genuinely valuable.
Selling Through Marketplaces: How Amazon, Etsy, and eBay Change Things
One of the most significant shifts in recent years is the rise of the deemed supplier model. When you sell through major online marketplaces like Amazon, Etsy, or eBay, the platform itself is often treated as the supplier for VAT purposes on sales to consumers. This applies to goods sold to UK consumers by overseas sellers, and to many cross-border transactions within the EU.
In practice, this means the marketplace collects and remits VAT on your behalf for qualifying transactions — which significantly reduces your own compliance burden. However, it doesn't remove it entirely. You still need to understand which of your sales are covered by the marketplace's deemed supplier rules, which are not, and how this interacts with your own VAT registration status.
Keep meticulous records of all marketplace sales, the VAT collected by the platform, and the territories involved. Tools like BizHub365 can help here — its bank statement import and transaction categorisation features make it easier to reconcile marketplace payouts against VAT obligations, keeping your bookkeeping clean even when sales are coming in from multiple channels and currencies.
Practical Steps to Get Your Cross-Border VAT Right
Here's a straightforward checklist to help you manage cross-border VAT compliance as a UK e-commerce business:
- Know your goods vs. digital services split. The rules differ materially, and conflating the two is a common source of errors.
- Review your fulfilment model. Are you shipping from UK stock, or holding inventory in EU warehouses? The latter triggers EU VAT registration obligations.
- Assess your EU sales volume. If you're regularly selling goods under €150 to EU consumers, IOSS registration (via an intermediary) is worth investigating.
- Speak to a VAT specialist. For digital services, marketplace arrangements, or multi-country stock holdings, a specialist adviser will pay for themselves many times over.
- Use your accounting software wisely. Ensure your system can handle zero-rated export sales, flag cross-border transactions, and produce the reports your accountant needs at VAT return time. BizHub365's VAT module, with its direct HMRC MTD API integration, ensures your UK VAT returns accurately reflect your export sales without the need for bridging software.
- Check marketplace agreements. Confirm exactly which transactions your marketplace platform is handling VAT on, and document this clearly for your records.
Conclusion: Don't Let VAT Complexity Stall Your International Growth
Cross-border VAT is undeniably complex, but it shouldn't be a barrier to growing your e-commerce business internationally. The key is understanding which rules apply to your specific business model — the goods you sell, where your customers are, and how you fulfil orders — then putting the right systems and advisers in place to stay compliant.
UK businesses that take the time to understand post-Brexit VAT rules, consider IOSS or OSS registration where appropriate, and keep clean, well-organised records are well placed to compete in international markets. Those that ignore the obligations, or assume nothing has changed since before Brexit, risk penalties, customs delays, and damaged customer relationships.
Start with what you know: your current sales data, your fulfilment setup, and your existing VAT registration status. From there, build outwards. The international opportunity is real — and with the right approach to compliance, it's well within reach.
