International VAT Specialists for E-commerce Businesses
Selling internationally creates significant opportunities for ecommerce businesses, but it also introduces increasingly complex VAT obligations. Whether you sell through Amazon FBA, Shopify, Etsy, TikTok Shop or your own website, understanding where you need to register, charge and report VAT is essential for remaining compliant and protecting profitability.
MWA Accounting supports growing ecommerce businesses across the UK with international VAT compliance, planning and advisory services. We help businesses understand their global VAT obligations, implement efficient financial systems and make commercially informed decisions as they expand into new markets.
Our international VAT services are designed to reduce complexity while helping businesses remain compliant across multiple jurisdictions. We regularly support ecommerce businesses trading throughout the UK, Europe, North America, Australia and other international markets.
Clients work with a dedicated accountant supported by experienced tax professionals and partner oversight where required. Where country-specific expertise is needed, we also work alongside trusted international VAT specialists to ensure clients receive the most appropriate technical advice.
We work with leading cloud accounting software including Sage, Xero and QuickBooks together with specialist ecommerce integrations such as A2X, Link My Books and Dext Commerce, helping businesses build efficient financial systems that scale alongside international growth.

FAQs
Not always. Since July 2021, the EU’s One Stop Shop (OSS) scheme allows you to register in one EU country and report all your EU B2C sales there. However, this only applies to certain sales — for example, physical goods shipped from one EU country to another. If you’re holding stock in multiple EU countries (such as through Amazon Pan-EU FBA), you’ll need VAT registration in each country where stock is stored. At MWA Accounting, we assess your exact supply chain to determine where registrations are required and handle the process for you.
OSS (One Stop Shop): For EU-based or non-EU sellers making B2C sales of goods within the EU. It allows you to file one consolidated VAT return instead of registering in every country where you sell.
IOSS (Import One Stop Shop): For distance sales of imported goods valued under €150. It simplifies the declaration and payment of VAT at the point of sale, improving customer experience and avoiding surprise import charges.
Both systems reduce admin, but choosing the right one depends on your sales model. We help clients set up and manage both schemes.
Amazon may collect and remit VAT on your behalf in certain cases (for example, sales to EU consumers under €150), but this does not cover all scenarios. If you store goods in EU warehouses (via Amazon FBA), you are responsible for local VAT registrations and returns in each country. Many sellers assume Amazon takes care of all VAT, but that’s a common misconception. We work with Amazon sellers to stay compliant and avoid costly suspensions.
VAT obligations vary by country. In the UK, the domestic threshold is £90,000 (as of 2024), but for EU distance sales there is a €10,000 EU-wide threshold. Once your cross-border sales exceed this, you must charge VAT in the customer’s country (usually via OSS). For non-EU countries, thresholds differ again — in the US, for instance, each state can set its own sales tax rules. We monitor your sales volumes and advise when and where new registrations are required.
Since Brexit, UK import VAT applies on goods entering from the EU and beyond. Most e-commerce businesses benefit from Postponed VAT Accounting (PVA), which allows you to declare import VAT on your UK VAT return instead of paying it upfront at customs. This is a major cash-flow advantage, especially for high-volume sellers. We help businesses set up PVA correctly and ensure import VAT is claimed back efficiently.
Yes, in many cases. If you’re VAT registered in the UK and purchase stock from EU or non-EU suppliers, you may be able to reclaim VAT (or equivalent taxes) depending on the country’s rules. This requires correct invoicing and evidence. We help clients process claims, avoid double taxation, and recover VAT where eligible.
Non-compliance can lead to penalties, interest charges, and even account suspensions on marketplaces like Amazon and eBay. In some jurisdictions, fines can be backdated several years. Worse still, non-compliance can damage your reputation with platforms and customers. At MWA Accounting, we put compliance systems in place so your business can scale internationally without interruption.
Yes. Many businesses contact us after discovering they should have registered for VAT overseas earlier or have unknowingly breached marketplace or country-specific VAT rules. We can review your position, identify any compliance issues, work alongside overseas advisers where required and help bring your business back into compliance while minimising disruption and unnecessary penalties.

Why Ecommerce Businesses Choose MWA for International VAT
International VAT is about far more than registering for VAT overseas or submitting returns. As ecommerce businesses grow, they often encounter increasingly complex issues involving marketplace rules, overseas fulfilment, customs procedures and changing international tax legislation.
At MWA Accounting, we work with ambitious ecommerce businesses at every stage of their growth journey, from first-time exporters to established multi-million-pound online retailers selling across multiple countries. We understand the practical challenges of expanding internationally because we support businesses dealing with them every day.
Our team combines specialist international VAT knowledge with wider commercial and accounting expertise, helping clients build financial systems that support sustainable growth rather than simply meeting compliance obligations. We regularly advise businesses selling through Amazon FBA, Shopify, Etsy, TikTok Shop and their own ecommerce websites, providing practical guidance that is commercially focused and easy to understand.
Where international tax rules become particularly complex, we also work alongside trusted overseas VAT specialists to ensure clients receive the right advice in every jurisdiction. This gives businesses the confidence to expand into new markets knowing their VAT compliance is being managed proactively.
Whether you’re registering for VAT in your first overseas country, navigating OSS and IOSS requirements, managing multiple warehouse locations or reviewing your international VAT strategy, our goal is simple: to remove complexity, reduce risk and allow you to focus on growing your business.
